TECHNICAL FIELD
[0002] The present invention relates to methods, devices, and
systems for improved helmet systems with fit pods and/or improved
comfort liners to enhance athletic performance by reducing
acceleration, dispersing impact forces and/or improving helmet
comfort and/or fit. If desired, the various improved helmet comfort
liner components can include modular components as well as
semi-custom and/or customized components for plug and play assembly
and/or retrofitting a commercially available helmet and/or other
item of protective clothing.
BACKGROUND OF THE INVENTION
[0003] Helmets and other protective apparel typically incorporate
impact absorbing structures to desirably prevent and/or reduce the
effect of collisions between the wearer and other stationary and/or
moving objects. For example, an athletic helmet typically protects
a skull and various other anatomical regions of the wearer from
collisions with the ground, equipment, other players and/or other
stationary and/or moving objects, while body pads and/or other
protective clothing seeks to protect other anatomical regions.
Helmets are typically designed with the primary goal of preventing
traumatic skull fractures and other blunt trauma, while body pads
and ballistic armors are primarily designed to cushion blows to
other anatomical regions and/or prevent/resist body penetration by
high velocity objects such as bullets and/or shell fragments.
[0004] However, the proper functioning of a helmet, its impact
structures and/or comfort liners is often highly dependent upon the
proper sizing and "fit" of the headgear to the wearer's head. A
helmet that does not fit and/or is uncomfortable to wear is often
not worn, resulting in the absence of the helmet when it is needed
for protection. Current helmet manufacturers often provide
sub-optimal methods for sizing and/or fitting of a helmet because
current fitting/sizing methods are generally ineffective in
accommodating the unique shape and size of every wearer's head,
resulting in an inaccurate sizing and/or shaping of the helmet
and/or impact structures for the wearer. Inaccurate sizing or
shaping of the helmet supports can allow undesirable movement
between the wearer's head and the helmet structures, as well as
increased pressure of the helmet on regions of the wearer's head
(i.e., "hot spots"), and such helmets may not effectively protect
the wearer's head from trauma and the effects of intense physical
contact and may perform improperly to absorb and/or significantly
ameliorate impacts. For example, a helmet that is too large for a
wearer's head can allow the user's head to move within the helmet,
allowing the user's head to contact sides of the helmet in an
undesirable manner during impact. Another major consideration in
protective headgear is wearer comfort--if the helmet is
uncomfortable or painful to wear, this discomfort may distract the
user's attention (potentially leading to more severe impacts)
and/or may cause the user to remove or displace the helmet prior to
the moment of impact. In a similar manner, a helmet that is too
small for the wearer's head may be uncomfortable or painful for the
wearer to wear.
[0005] Furthermore, the use of outdated impact mitigation
technologies and/or comfort liners may, in certain instances,
greatly reduce the effectiveness of the helmet system and
potentially lead to increased incidence and/or severity of
injuries. Many conventional football helmets are manufactured with
inflatable comfort liners that may be sometimes combined with soft
foam comfort liners and/or other materials in an effort to help
attenuate impact forces incident to the helmet. These inflatable
liners can have a plurality of separate inflatable cells, with
these cells adjacently arranged into a general shape inside the
helmet, often with interconnect air passageways and the inflatable
cells often include a separate valve-controlled inflation tube that
may extend out the back or side of the helmet. To "fit" the helmet,
the wearer or an assistant (often referred to as the "sizer") may
increase or decrease the pressure of air or other fluid/gas within
the inflatable comfort liner to desirably increase and/or decrease
the size of the cells, while seeking to improve the wearer's fit,
comfort and protection. Unfortunately, inflatable liners and
related technology often function sub-optimally, in that the
inflatable cells are prone to leakage, damage and are highly
sensitive to environmental temperatures (i.e., they commonly
increase or decrease in size due to temperature fluctuations and/or
air pressure changes). Inflatable cells also require more frequent
of adjustment (or "spot checks") in comparison to foams and/or
other materials to maintain proper sizing in-between pressurization
and/or depressurization cycles. In addition, inflatable cells often
suffer from a lack of uniform inflation, where some portions of the
inflatable comfort liner may be over-inflated and other portions
under-inflated; and the distribution of inflatable cells may not be
uniform and/or may cause a tilting effect (i.e., inflatable jaw
pads or side pads) or a "lift effect" (with an inflatable crown
pad) on the helmet. Such negative characteristics of the inflatable
comfort liners can adversely affect the fit of the helmet and
reduce or eliminate any protection the helmet presumes to
provide.
[0006] In addition, research has been revealing that traumatic
brain injuries (TBI's) are not only caused by linear impacts, but
impacts resulting from oblique, tangential and/or rotational
acceleration because the brain is sensitive to rotational motion.
Rotational motion and/or acceleration may cause TBI's that results
from interrupting the speed of the body relative to the head, which
the unrestricted movement of the head occurs out of synchrony with
the movement of the neck, torso, and/or lower limbs of the body.
Injuries received by players, such as concussions, subdural
hemorrhage, hematomas and diffuse axonal injury, can be more easily
caused by rotational head motion. Unfortunately, current helmet
designs to not adequately protect the head from TBI's due to
oblique, tangential and/or rotational acceleration.
BRIEF SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION
[0050] The fit pod assemblies and the improved protective helmet
system will enhance and/or optimize a player's fit and/or impact
protection. The fit pod assemblies may be desirably available in
different thicknesses, different shapes and configurations,
different foam layers, so they may be easily adapted and/or
tailored to a specific wearer's sport, position and/or occupation.
The one or more modular fit pod assemblies are removably connected
to an interior surface of a helmet and may be positioned around
various locations of the wearer's head. Such plurality of fit pod
assemblies may include one or more of the following locations: a
frontal assembly (or front), a crown assembly, an occipital
assembly (or lower-back), a mid-back assembly, a parietal assembly
(or midline), and a temporal assembly (right and/or left sides),
and/or any combination(s) thereof. At least a portion of the fit
pod assemblies may be removably coupled to at least one inner
layer, impact mitigation layer, outer layer and/or any combination
thereof to facilitate energy absorption, reduce angular motion
and/or rotational motion of the wearer after impact, enhance fit
and comfort. Since the fit pod assemblies can be tailored to the
particular demands of each wearer, the fit pod assemblies may be
retrofitted to a commercially available helmet; and/or (2)
incorporated into a new, customized helmet system with
wearer-specific attributes.
[0051] Furthermore, the one or more fit pod assemblies have a
unique construction that further enhances flexibility of the fit
pod and/or fit pod assembly to conform to the natural shape or
contours of the wearer's head. The one or more fit pod and/or fit
pod assemblies comprise a plurality of channels or grooves disposed
on a top layer and have flexible and/or stretchable materials for
the top and bottom layers that allows the one or more fit pods and
fit pod assemblies to easily deform from a flattened configuration
to a curved configuration. The plurality of channels or grooves
have a channel width, and the channel width changes from a first
position to a second position. The first position being a neutral
uncoupled position, and the second position having at least one of
the plurality of channels with a decreased channel width after
being removably coupled to the helmet.
[0052] The various fit pod assemblies and/or protective helmet
components and designs provided herein are depicted with respect to
American football, but it should be understood that the various
devices, methods and/or components may be suitable for use in
protecting players in various other athletic sports, as well as
other occupations that require protection, such as law enforcement,
military, construction and/or informal training session uses. For
example, the embodiments of the present invention may be suitable
for use by individuals engaged in athletic activities such as
baseball, bowling, boxing, cricket, cycling, motorcycling, golf,
hockey, lacrosse, soccer, rowing, rugby, running, skating,
skateboarding, skiing, snowboarding, surfing, swimming, table
tennis, tennis, or volleyball, or during training sessions related
thereto.

[0055] FIG. 2 depicts an exploded view of an alternate embodiment
of an improved protective helmet system 200. In one exemplary
embodiment, the improved protective helmet system 200 may comprise
a helmet, a fit pod layer 202, and a comfort liner 210. The helmet

comfort liner 210 may comprise a first layer, a second layer, and a
foam layer, while in at least one alternative embodiment the
comfort liner may be formed from thermoformed foam (optionally
without one or both of the inner and outer layers). The foam layer
may include a plurality of segmented foam pads, each of the
plurality of segmented foam pads are separated by gap. The foam
layer is disposed between the first and second layer. The gap has a
thickness, the thickness allowing substantial flexibility and/or a
pivotal connection. Each of the plurality of fit pod assemblies may
include the fit pod and a connection mechanism. At least a portion
of the fit pod assemblies may be removably coupled to at least one
inner layer, impact mitigation layer, outer layer, comfort liner
and/or any combination thereof to facilitate energy absorption,

[0056] Helmet
[0057] The helmet having at least one outer layer, an inner layer
and an impact mitigation layer (not shown) disposed between the
inner and outer layer, a supplemental frontal fit pod, and/or any
combination thereof. The protective helmet may further comprise a
chinstrap (not shown), a faceguard (not shown) and/or a visor (not
shown).
[0058] FIGS. 3A-3B and 4A-4B depict isometric views of different
embodiments of an outer layer. The outer shell or outer layer
300,400 may be manufactured from a relatively rigid material or
rigid material, such as polyethylene, nylon, polycarbonate
materials, acrylonitrile Butadiene Styrene (ABS), polyester resin
with fiberglass, thermosetting plastics, and/or any other rigid
thermoplastic materials. Alternately, the outer shell 1060 may be
manufactured from a relatively deformable material, such as
polyurethane and/or high-density polyethylene, where such material
allows some flexibility and/or local deformation of the outer layer
502 and/or the impact mitigation layer 504 upon impact 508, but
provide enough rigidity to prevent the breakage or damage to the
helmet as shown in FIG. 5C-5D.
[0059] FIGS. 5A-5D depict cross-sectional views of one embodiment
of a protective helmet 500 showing the outer layer 502, the impact
mitigation layer 504 and the inner shell 506. The impact mitigation
layer 504 may comprise one or more impact mitigation structures.
The impact mitigation structures may comprise at least a portion of
filaments, at least a portion of laterally supported filament (LSF)
structures, at least a portion of auxetic structures, at least a
portion of undulated structures, and/or any combination thereof.
impact mitigation layers may comprise a portion of at least one of:
filaments, laterally supported filaments, auxetic structures,
impact foam or foam layer, TPU cones, inflatable bladders, shock
bonnets, and/or any combination thereof.
[0060] In one embodiment, the impact mitigating structures and/or
impact mitigation layers can comprise at least a portion of
filaments. The at least a portion of filaments may be thin,
longitudinally extending members having a 3:1 to 1,000:1 aspect
ratio (having its length being greater than its width or diameter).
The at least a portion of filaments may be shaped and configured to
deform non-linearly in response to an impact force. The non-linear
deformation behavior is expected to provide improved protection
against high-impact forces, and/or oblique forces. The non-linear
deformation behavior is described by at least a portion of the
filaments stress-strain profile. The non-linear stress-strain
profile illustrates that there can be an initial rapid increase in
force (region I) followed by a change in slope that may be flat,
decreasing or increasing slope (region II), followed by a third
region with a different slope (region III).
[0061] In another embodiment, the at least a portion of the
filaments may comprise filaments that buckle in response to an
incident force, where buckling may be characterized by a localized,
sudden failure of the filament structure subjected to high
compressive stress, where the actual compressive stress at the
point of failure is less than the ultimate compressive stress that
the material is capable of withstanding. Furthermore, the at least
a portion of the filaments may be configured to deform elastically,
allowing the at least a portion of the filaments to substantially
return to their initial configuration once the external force is
removed.
[0062] In another embodiment, the impact mitigating structures
and/or impact mitigation layers can comprise at least a portion of
a plurality of filaments that are interconnected by laterally
positioned walls or sheets or other supplemental filaments in a
polygonal configuration, otherwise known as laterally supported
filaments (LSF). The at least a portion of the LSF structures,
where the filaments are arranged in a hexagonal pattern
interconnected by laterally positioned walls or other supplemental
filaments. Alternatively, other polygonal structures known in the
art may be contemplated, such as triangular, square, pentagonal,
hexagonal, septagonal, octagonal, and/or any combination thereof. A
plurality of sheets or lateral walls can be secured between
adjacent pairs of filaments with each filament having a pair of
lateral walls attached thereto. In the disclosed embodiment, the
lateral walls can be oriented approximately 120 degrees apart about
the filament axis (preferably, it may be 90 to 135 degrees apart
about the filament axis), with each lateral wall extending
substantially along the longitudinal length of the filament. In
addition, each of the lateral walls may be oriented differently,
and have symmetric orientation or asymmetric orientation. The
shape, wall thickness or diameter, height, and configuration of the
lateral walls, supplemental filaments and/or filaments may vary to
"tune" or "tailor" the structures to a desired performance. For
example, one embodiment of a hexagonal structure may have a tapered
configuration. The hexagonal structure can have a top surface and a
bottom surface, with the bottom surface perimeter (and/or bottom
surface thickness/diameter of the individual elements) that may be
larger than the corresponding top surface perimeter (and/or
individual element thickness/diameter). In another example, the
hexagonal structure can have an upper ridge. The upper ridge can
also facilitate connection to another structure, such as an inner
surface of a helmet, an item of protective clothing, and/or a
mechanical connection (e.g., a grommet or plug having an enlarged
tip that is desirably slightly larger than the opening in the upper
ridge of the hexagonal element).
[0063] Furthermore, the polygonal or hexagonal structures may be
manufactured as individual structures or in a patterned array. The
individual structures can be manufactured using an extrusion,
investment casting or injection molding process. Each individual
polygonal or hexagonal structure may be affixed directly to a base
in a custom location or pattern that may be arranged in continuous
or segmented array. Also, they may have the same shape and
configuration with repeating symmetrical arrangement or
asymmetrical arrangement and/or different shape and configurations
with repeating symmetrical arrangement or asymmetrical
arrangement.
[0064] Conversely, the polygonal or hexagonal structures may be
manufactured directly into a patterned array that is affixed to at
least one base membrane. The base membrane may be manufactured with
a polymeric or foam material. The polymeric or foam material may be
flexible and/or elastic to allows it to be easily bent, twisted or
flexed to conform to complex surfaces. Alternatively, the polymeric
and/or foam material may be substantially rigid. The manufacturing
of each patterned array of polygonal or hexagonal structures may
include extrusion, investment casting or injection molding process.
The base membrane with the polygonal or hexagonal structures may be
affixed directly to at least a portion of the base or the entirety.
Affixing each pattered array of polygonal or hexagonal structures
may be arranged in continuous or segmented arrays. Also, the
polygonal or hexagonal structures may have the same shape and
configuration with repeating symmetrical arrangement or
asymmetrical arrangement and/or different shape and configurations
with repeating symmetrical arrangement or asymmetrical
arrangement.
[0065] In another embodiment, the impact mitigation structure may
comprise at least a portion of auxetic structures. The auxetic
structures may include a plurality of interconnected members
forming an array of reentrant shapes positioned on the flexible
head layer. Such auxetic structures may be coupled or affixed to
the protective enclosure base as a continuous layer or in segmented
arrays. The term "auxetic" generally refers to a material or
structure that has a negative Poisson ratio, when stretched,
auxetic materials or structures become thicker (as opposed to
thinner) in a direction perpendicular to the applied force. Such
auxetic structures can result in high energy absorption and/or
fracture resistance. In particular, when a force is applied to the
auxetic material or structure, the impact can cause it to expand
(or contract) in one direction, resulting in associated expansion
(or contraction) in a perpendicular direction. It should be
recognized that those skilled in the art could utilize auxetic
structures to include differently shaped segments or other
structural members and different shaped voids.
[0066] In another embodiment, the impact mitigation structures may
comprise undulated structures. The undulated structures may
comprise chevron pattern, herringbone pattern, and/or zig zag
pattern. Such undulated structures allow large elastic deformations
by releasing strain--a structural deformation, then returning to
its original configuration after the impact is removed.
[0067] The inner shell or inner layer 506 may be manufactured from
a relatively rigid or rigid material. The inner shell or inner
layer 506 being nested within the impact mitigation layer 504. The
inner shell 506 having an exterior surface and an interior surface,
the at least a portion of the exterior surface of the inner shell
506 may contact an exterior surface of the impact mitigation layer
504. The at least one inner shell 506 being a continuous shell
and/or a two-piece shell that conforms and surrounds the head of
the wearer. Accordingly, the at least one inner shell 506 may be a
rigid material. The at least one inner shell 506 may be more rigid
than the outer shell 502 and/or more rigid than the impact
mitigation layer 504. In some embodiments, the inner shell 506 is
five to 100 times stiffer or more rigid than the outer shell 502
and/or the impact mitigation layer 504. The rigid material may
comprise polycarbonate (PC). Alternatively, the inner shell 506
comprises a relatively rigid material or relatively stiff material.
The relatively rigid material may be stiff or rigid enough to
withstand breakage or cracking, but flexible enough to deform
slightly and distribute incident forces after an impact. The at
least one inner shell 506 may comprise a thermoplastic material.
Thermoplastic materials may comprise polyurethane, polycarbonate,
polypropylene, polyether block amide, and/or any combinations
thereof. Alternatively, the inner shell 506 may comprise a
deformable material, such as polyurethane and/or high-density
polyethylene, where such material allows some flexibility and/or
local deformation upon impact, but provide enough rigidity to
prevent the breakage or damage to the helmet.
[0068] FIGS. 6A-6B depicts various views of an alternate embodiment
of an inner shell or inner layer 600. The inner shell or inner
layer 600 substantially surrounds the head of the wearer and
conforms to the shape of the wearer's head. The inner shell may
comprise a first plurality of openings 602, a second plurality of
openings 606, and a plurality of retention posts 604. The first
plurality of openings 602 may be sized and configured to receive a
portion of the fit pod connection mechanism (not shown). Such size
and configuration will allow the portion of the fit pod connection
mechanism to be compressed, and pushed through the first plurality
of openings, and once through, the at least a portion of the
connection mechanism will expand and stay in place. The first
plurality of openings 602 may match or substantially match the
shape of the fit pod connection mechanism to prevent unintended
rotation, misalignment or improper orientation. Furthermore, the
connection mechanism may comprise an alignment feature, a plurality
of detents and/or a detent body that allows for intuitive placement
of the fit pod assembly in the correct direction to prevent
improper placement or orientation. Tactile feedback with a "snap"
may be desired. Accordingly, a second plurality of openings may be
sized and configured to secure other components of the helmet, such
as a portion of the outer layer and/or the impact mitigation layer.
The plurality of retention posts 604 extend perpendicularly from an
external surface of the inner layer 600. Alternatively, the
retention posts 605 may extend to an oblique angle, the oblique
angle ranging from 5-30 degrees. The retention posts 605 may be
cylindrically shaped and may comprise a threaded hole for screw
attachment to the impact mitigation layer and/or the outer
layer.
[0069] Fit Pod Assemblies
[0070] The protective helmet system may comprise a helmet and a
modular fit pod layer. The modular fit pod layer may comprise a
plurality of fit pod assemblies positioned in different regions
around the wearer's head. The plurality of fit pod assemblies may
be removably coupled to an inner layer or inner shell, and/or
removably coupled to a base layer. The base layer may comprise a
polymer, the polymer may comprise polycarbonate or a flexible
material. Each of the plurality fit pod assemblies comprise a fit
pod and a connection mechanism. The plurality of fit pod assemblies
may be provided in different thicknesses to accommodate different
needs of each wearer. Each of the plurality of fit pod assemblies
may be different thicknesses or the same thicknesses.
[0071] In various embodiments, a helmet or other item of protective
clothing or equipment or garment may incorporate one or more fit
pod layers and/or fit pod assemblies. The one or more pod
assemblies may include at least one fit pod (known as "pods" or
"modular pods") and/or a connecting mechanism. The one or more fit
pod assemblies can be modular and placed into any configuration
within the helmet. Each of the fit pod assemblies may include
easily removable connections to couple to the helmet or various
components thereof. Each of the plurality of fit pod assemblies may
be manufactured to accommodate and protect the desired region of
the wearer's head. Such plurality of fit pod assemblies may include
regions such as one or more of the following: a frontal assembly
(or front), a crown assembly, an occipital assembly (or
lower-back), a mid-back assembly (right and/or left sides), a
parietal assembly (or midline), and a temporal assembly (right
and/or left sides), jaw assembly and/or any combination(s)
thereof.
[0072] FIGS. 7A and 7B depict perspective and cross-sectional views
of one exemplary embodiment of a fit pod 700. The fit pod 700 may
be generally shaped as a regular or irregular polygon, the regular
polygon may comprise a triangle, square, rectangle, pentagon,
hexagon, septagon, octagon, and/or any combination thereof. The fit
pod 700 may comprise one or more channels 702 and one or more vent
openings (not shown). The fit pod 700 may comprise a top surface
716 and a bottom surface 718. The one or more channels 702 may be
disposed onto the top surface 716, the one or more channels 702 may
be spaced apart from each other in a symmetric or non-symmetric
pattern, and the one or more channels 702 may extend to the
perimeter of fit pod. The one or more channels 702 may extend from

channels may have a first and/or second end, which at least the
first or second end of each of the one or more channels 702 may
intersect at an intersection point 704. The one or more channels
may comprise a width, a depth, and a length. The channel depth
and/or width facilitates the flexibility of the fit pod 700. For
example, a larger depth can increase the flexibility whether folded
inward or outward. Also, a larger width allows increased deflection
when folded inwards. Therefore, when the fit pods are coupled to
the helmet, the fit pod 700 folds inward from a flat configuration
to a curved configuration, thereby decreasing or narrowing the
channel width. In one embodiment, the channel width may have a
first position, the first position being a non-coupled, neutral
position, and the second position, the second position being a
coupled position (e.g., coupled to the helmet), where the first
position channel width is greater than the second position channel
width.
[0073] The fit pod 700 may comprise at least one bottom layer 708,
at least one top layer 706, and/or at least one foam layer 710,
712. The fit pod 700 may further comprise an impact mitigation
structure (not shown), The at least one bottom layer 708 or least
one top layer 706 may comprise at least one foam material or at
least one foam layer, a plastic material, a resilient fabric that
may be a two-way or four-way stretch material and/or any elastic
material. The plastic material may comprise an acrylic, a
polypropylene, a polycarbonate, an acrylonitrile-butadiene-styrene,
a polyethylene, a polyethylene terephthalate, and/or any
combination thereof. In one embodiment, the top layer and/or bottom
layer may comprise a 2-way or 4 way stretch fabric and a polymer
film. The polymer films comprise a polyethylene film, polypropylene
film, a polyurethane film, a nylon film, a polyester film, a
polyvinyl chloride film and/or any combination thereof. The polymer
film may be coupled or laminated to the 2-way or 4-way stretch
fabric. The at least one top layer 706 and at least one bottom
layer 708 may be the same material, or they may be different
materials. The at least one bottom layer 708 may extend beyond the

least one foam layer 710, 712 may be disposed between the bottom
layer 708 and/or at least one top layer 706. The impact mitigation
structure may be coupled to the at least one foam layer 710,712
and/or the least one bottom layer 708. Such coupling may be
accomplished by using adhesives, molding, heat and/or ultrasonic
welding, sintering or any other method known in the art.
Alternatively, the impact mitigating structures may be
"free-floating" between the base or bottom layer 708 and the top
layer 706. Furthermore, impact mitigation structure may be the same
material as the at least one foam layer 710,712. Alternatively, the
impact mitigation structure may be a different material as the at
least one foam layer 710,712.

comfort foam (open cell low density foam), TPU foam and/or any
combination thereof. The at least one foam layer may have an
open-cell structure or closed-cell structure. The at least one foam
layer can be further tailored to obtain specific characteristics,
such as anti-static, breathable, conductive, hydrophilic,
high-tensile, high-tear, controlled elongation, and/or any
combination thereof. The foam layer 710, 712 and/or the impact
mitigation structure may have a thickness ranging from 7 mm to 25
mm.
[0076] The at least one bottom layer 110 and/or the at least one
top layer 100 can surround the complete perimeter of the impact
mitigating structure 130 and/or the at least one foam layer 120,
completely enclosing the impact mitigation structure.

portions.
[0079] In another embodiment, the modular fit pod 900 may include a
first surface 902, and a second surface 910, while in other
embodiments the modular pod 900 may comprise a thermo-foamed foam
layer (optionally without first 902 and/or second surfaces 910).

of a connection mechanism 806 (see FIG. 8C).
[0080] The one or more grooves or channels 906 may have a groove
width 922 and a groove height 924. By modifying the groove or
channel width 922 and groove or channel height 924, the flexibility
of the fit pod 900 changes. The larger the groove width 922 and
groove height, the fit pod 900 flexibility increases. The smaller
the groove width 922 and groove height, the fit pod 900 flexibility
decreases. The groove width 922 changes from the flattened
configuration at the neutral, uncoupled state, to a smaller groove
width 922 changing the fit pod 900 into a curved configuration. The
collective groove width 922 of each of the one or more grooves or
channels 906 determines the inward curvature or the flexible
distance once the second ends 916 of the grooves or channels 906
abut or mate providing a positive stop. Furthermore, the fit pods
900 can be provided in a series of overall sizes and/or thicknesses
920. The one or more fit pods 900 having a 1/4'' thickness
progressively up to a 1.25'' or greater thickness 920 (preferably,
0.25 inches or greater). Desirably, the different thickness 920 fit
pods can be provided with similar external dimensions (i.e., height
and/or width), with only the thickness 920 differing to any
substantial degree, allowing different thickness fit pods to be
"mixed and matched" for use with a single helmet, helmet liner or
other component, and/or other item of protective clothing or
equipment.
[0081] FIGS. 10A-10C depict various views of one embodiment of a
connection mechanism 1000. The connection mechanism 1000 having a
height 1006, a width 1004 and a depth 1010. The connection
mechanism 1000 comprises a base 1012, a plurality of longitudinally
extending members 1016, and a plurality of detents 1014. The
longitudinally extending members 1016 having a member thickness
1008 and a member width 1002, and each of the longitudinally
extending members 1016 extending longitudinally away from the base
1012 in the same plane of the base 1012. The longitudinally
extending members 1016 may be spaced apart from each other
symmetrically or asymmetrically. The longitudinally extending
members 1016 may be planar and/or flat. The plurality of detents
1014 extends perpendicularly or substantially perpendicularly away
from the base 1012, which "substantially" means that the detents
1014 may have a slight oblique angle from 1 degree to 10 degrees
from being perpendicular. The plurality of detents 1014 may be
positioned between the longitudinally extending members 1016.
Alternatively, the plurality of detents 1014 may be aligned with
the longitudinally extending members 1016. The plurality of detents
1014 may arranged into a shape and/or comprise a shape, the shape
may match or substantially match the fit pod connection openings.
The shape may comprise a circle, an oval, an ellipse, a polygon
and/or irregular polygon.
[0082] The plurality of detents 1014 having a first portion 1018
and a second portion 1020, the second portion having a protrusion,
where the protrusion is larger than the connection mechanism
opening 602 (see FIG. 6A-6C), and the protrusion having a bottom
surface that mates with an external surface of the inner shell or
inner layer 600. The plurality of detents 1014 will flex inward
when being inserted into the connection mechanism opening 602, and
once the plurality of detents 1014 are through, the plurality of
detents 1014 will return to its unstressed state by expanding, and
the expansion will secure the connection mechanism 1000 in place.
Therefore, to remove the connection mechanism 1000 from the inner
shell or layer 600, the plurality of detents 1014 can be pinched
together to release. Accordingly, the detents 1014 can facilitate
the desired alignment. The detents 1014 intuitively allows the user
to insert into the connection mechanism openings 602 (see FIGS.
6A-6C) into a proper orientation and placement, resulting in little
or no confusion for securing the pods to the inner shell or layer
600. Such design of the connection mechanism 1000 and/or the
detents 1014 also remove the ability of the fit pods to rotate.
[0083] In another embodiment, the connection mechanism 1000 may be
coupled to a fit pod 900 (see FIG. 9A-9H) to create a fit pod
assembly 800 (see FIG. 8A-8C). The connection mechanism 1000 may
have a first portion and a second portion. The first portion having
a top surface and a bottom surface. At least a portion of the
second portion being inserted into the connection mechanism opening

mechanism opening 602, and the top surface of the first portion
mates with the inner surface of the inner shell or layer 600. The
bottom surface of first portion mates or coupled to fit pod 900
bottom surface 910 (see FIG. 9A-9H). The connection mechanism 1000
may comprise a polymer material known in the art. More
specifically, the polymer material allows sufficient flexibility
and can withstand repeated cycles of engagement and disengagement
from the modular pod and/or the helmet inner layer. Alternatively,
other types of connection mechanisms may be utilized, which include
Velcro (hook and loop), adhesives, snaps, screws, press-fittings,
magnetic mechanisms, and/or any combination thereof. Furthermore,
the connection mechanism may comprise an alignment feature, the
alignment feature allows for intuitive placement of the fit pod
assembly in the correct direction to prevent improper placement or
orientation. Tactile feedback with a "snap" may be desired.
[0084] FIGS. 11A-11H depict various views of an alternate
embodiment of a fit pod assembly 1100. The fit pod assembly 1100

external dimensions (i.e., height and/or width), with only the
thickness 1112 differing to any substantial degree, allowing
different thickness fit pods to be "mixed and matched" for use with
a single helmet, helmet liner or other component, and/or other item

assembly 1700 comprises a fit pod 1702 and a connection mechanism
1704. The connection mechanism 1704 coupled to the fit pod 1702. In
one embodiment, the fit pod 1702 comprises a single foam layer. The
single foam layer may be molded or thermoformed into a desired
shape. The shape may be triangular or generally triangular, where
the corners become sharp angled corners to rounded corners. Other
shapes may be contemplated, such a as regular or irregular
polygons. The single foam layer may comprise a foam material. The
modular fit pod 1702 may further comprise a single impact
mitigation structure (not shown), optionally without a top or
bottom layer. The at least one foam layer or foam material can
include polymeric foams, quantum foam, polyethylene foam,
thermoplastic polyurethane foam (foam rubber), XPS foam,
polystyrene, phenolic, memory foam (traditional, open cell, or
gel), impact absorbing foam (e.g., VN600), latex rubber foam,
convoluted foam ("egg create foam"), Ariaprene, Evlon foam, impact
hardening foam, 4.0 Custula comfort foam (open cell low density
foam) and/or any combination thereof. The at least one foam layer
may have an open-cell structure or closed-cell structure. The at
least one foam layer can be further tailored to obtain specific
characteristics, such as anti-static, breathable, conductive,
hydrophilic, high-tensile, high-tear, controlled elongation, and/or
any combination thereof.
[0104] The fit pod 1702 may comprise a top surface 1706 and a
bottom surface 1708. The top surface 1706 having a plurality of
channels or grooves 1710 disposed within, the plurality of channels
1710 having a channel width and channel depth. The plurality of
channels 1710 are spaced apart from each other symmetrically or
asymmetrically. The spaced part plurality of channels 1710 may
segment the top surface 1706 into two or more segmented surfaces.
The plurality of channels 1710 may extend from the top surface 1706
towards a portion of the bottom surface 1708. The plurality of
channels 1710 may comprise at least one end that intersects at an
intersection point 1712. The connection mechanism 1704 is the
similar or same connection mechanism disclosed in FIGS. 14A-14H.
The connection mechanism 1704 being coupled to the bottom surface
1708 of the fit pod 1702. More specifically, the connection
mechanism 1704 having a top surface and a bottom surface. The
bottom surface of the connection mechanism 1704 being coupled to
the bottom surface 1708 of the fit pod 1702. The top surface of the
connection mechanism 1704 may have a detent body extending
perpendicularly or substantially perpendicular (being 1 to 15
degrees oblique from perpendicular) from the top surface.
Accordingly, the detents body can facilitate the desired alignment.
The detents body intuitively allows the user to insert into the
connection mechanism openings into a proper orientation and
placement, resulting in little or no confusion for securing the
pods to the inner shell or layer. Such design of the connection
mechanism 1704 and/or the detents body also remove the ability of
the fit pods to rotate. The detent body having a shape, the detent
body shape matching or substantially matching the connection
mechanism opening in the inner shell or layer to prevent
misalignment, misplacement or improper orientation. Alternatively,
the detent body being shaped and configured to be disposed within
the connection mechanism opening of the inner shell or layer to
prevent misalignment, misplacement or improper orientation. In
addition, the fit pods 1702 may further comprise a plurality of
vent openings (not shown). The vent openings may extend through the
bottom surface 1708 of the fit pod 1702. The vent openings may be
disposed within the plurality of channels 1710.
[0105] In one embodiment, fit pods 1702 can be provided in a series
of sizes and/or thicknesses. For example, a first pod having a
1/4'' thickness progressively up to a fourth pod with 1'' or 1.25''
or greater thickness (preferably, 0.25 inches or greater).
Desirably, the different thickness triangular pods can be provided
with similar external dimensions (i.e., height and/or width), with
only the thickness differing to any substantial degree, allowing
different thickness fit pods to be "mixed and matched" for use with
a single helmet liner or other component, and/or other item of
protective clothing.
[0106] In one exemplary embodiment, an improved helmet system may
comprise features to help protect against oblique, tangential
and/or rotational acceleration as shown in FIG. 18A-18E and FIG.
19. The improved helmet system may comprise a helmet, one or more
modular fit pod assemblies 1800 and/or fit pod layer(s). The one or
more fit pod assemblies 1800 and/or fit pod layer comprises a fit
pod, a connection mechanism, and an elastomeric support mechanism.
Alternatively, the improved helmet system may comprise a helmet,
one or more impact mitigation structures, and/or an elastomeric
support mechanism. The helmet may include an outer layer. The
helmet may further comprise an inner layer and/or an impact
mitigation layer disposed on an inner surface of the outer layer,
and/or between the outer layer or inner layer, and/or any
combination thereof. The fit pod layer may comprise one or more
modular fit pod assemblies. Each of the fit pod assemblies 1800,
1810, 1812, 1818 may also include a fit pod 1802, a connection
mechanism 1804, and an elastomeric support mechanism or structure
1806, 1820. The fit pod 1802 may further comprise a top surface
(not shown) and a bottom surface (not shown). The one or more fit
pods may comprise a single layer foam material and/or a
multi-layered foam material construction as disclosed herein.
[0107] The one or more fit pod assemblies 1800, 1810, 1812, 1818
may further comprise a low-friction layer 1808, the low friction
layer 1808 facilitates the sliding of the elastomeric support
structure 1806, 1820 with the connection mechanism 1804 relative to
the fit pod 1802. The low friction layer 1808 comprises PTFE,
polyimide, PEEK, PPS, Nylon, Acetal, Polyester, and/or any other
low-friction materials known in the art. The low friction layer
1808 may further comprise a lubricant to enhance the low-friction
properties. The low-friction layer 1808 may be coupled to the
bottom surface of the fit pod 1802. The low-friction layer 1808 may
match or substantially match the perimeter of the fit pod 1802. The
low friction layer 1808 may extend beyond the perimeter of the fit
pod 1802 to produce a flange or edge.
[0108] The elastomeric support mechanism allows the one or more fit
pod assemblies 1800, 1810, 1812, 1818 to be slidably movable from a
first position to a second position. The elastomeric support
mechanism 1806, 1820, links the fit pod 1802 to connection
mechanism. The elastomeric support mechanism 1806, 1820 may be
adjusted in stiffness to allow the fit pod 1802 to slide in shear
when desired during in impact to the helmet. The elastomeric
support structure stretches and/or articulates to allow the shear
sliding of the fit pod 1802 relative to the elastomeric support
mechanism 1806, 1820 during impact and then returns the fit pod
1802 back to the original neutral position after the impact. The
first position which the connection mechanism 1804 is positioned in
a neutral position, to a second position, which the connection
mechanism 1804 is posited laterally from the neutral position. The
elastomeric support mechanism may be removably coupled or
integrally coupled to the each one or more fit pods 1802. The
addition of an elastomeric support mechanism 1806, 1820 to one or
more fit pods and/or one or more impact mitigation layers is
advantageous over traditional helmets. Such elastomeric support
mechanism 1806, 1820 facilitates sliding or lateral movement of the
fit pod assembly relative to the head of the wearer rather than
outer shell of the helmet relative to the head or outer shell of
the helmet relative to an inner shell.
[0109] The elastomeric support mechanism 1806, 1820 may comprise an
comprises an elastomeric material with elastomeric properties. The
elastomeric material may be rubber materials or thermoplastic
elastomers. The elastomeric structure may comprise elastomeric
frame or structure 1806, a woven elastomeric fabric or cover (such
as a 2-way or 4-way stretch fabric), an fabric or cover 1820 with
elastomeric properties (e.g. a woven, knit graft), and/or one or
more springs (not shown). For example, in one embodiment, the
elastomeric mechanism 1806 may comprise a frame 1810, a base 1814,
and a plurality of struts 1812. The frame 1810 is shaped and
configured to match or substantially match the perimeter of each of
the one or more fit pods 1802. The substantially match may comprise
a perimeter that may be offset from 1-5 mm from the perimeter edge
of each of the one or more fit pods.
[0110] The one or more struts and/or the plurality of struts 1812
having a length, a first end and a second end. The first end of the
one or more struts is coupled to a portion of the frame 1810, and
the second end is coupled to a portion of the base 1814. The one or
more struts 1812 may have a variety of configurations, along the
length. The configurations may include a uniform straight strut,
curved strut, undulated strut, and/or any combinations thereof, The
configurations along the length may be modified, adjusted and/or
tuned to customize the allowable shear distance (or lateral
distance) that may be acceptable for the particular sport and/or
rotational motion. The one or more struts 1812 may further comprise
one or more elastomeric transitions that has different elastomeric
modulus, tensile stiffness, elastic properties, and/or flexibility
when under tension. For example, the one or more struts 1812 may
comprise a first portion, and a second portion. The first portion
and the second portion may be different elastomeric materials with
different properties, or they may comprise the same material with
same properties. The first portion may have a first transition with
stiffer elastomeric property than the second portion having a
second transition. The elastomeric mechanism or structure may
comprise different elastomeric materials, such as rubber, rubber
blends, thermoplastic elastomers, and/or any elastomeric material,
or material with elastomeric properties that contains elastic
recovery after deformation in compression or tension. The base 1814
may further comprise posts 1816. The posts 1816 extend
perpendicularly away from the base 1814. At least a portion of the
posts 1816 are sized and configured to fit within one or more
openings on the connection mechanism 1804. The elastomeric
structure 1806 may be coupled to the low friction layer 1808 and/or
it may be coupled onto the fit pod 1802 directly.
[0111] The connection mechanism 1804 may be coupled onto the
elastomeric mechanism 1806. The connection mechanism 1804 may have
a shape that matches or substantially matches the perimeter of the
fit pod 1802. Alternatively, the shape may comprise a polygon or an
irregular polygon. The connection mechanism 1806 comprises a first
portion 1826 and a second portion 1822. The first portion 1826 may
include a plurality of openings 1824, the plurality of openings
1824 sized and configured to receive at least a portion of the
posts 1816 to secure the connection mechanism 1826. The second
portion 1822 extends perpendicularly away from the first portion
1822, the second portion 1822 sized and configured to fit within
the connection mechanism openings within the inner layer or inner
shell (not shown).
[0112] In another embodiment, the elastomeric support mechanism
1806 may comprise a flexible, elastomeric cover 1820. The fit pod
1802 and/or a portion of the connection mechanism 1804 may be
disposed within the elastomeric cover 1820. The elastomeric cover
1820 may enclose the entirety of the fit pod 1802 and/or at least a
portion of the fit pod 1802. In an alternative embodiment, the
elastomeric support mechanism 1806 may comprise both an elastomeric
cover 1820 and an elastomeric structure 1806.
[0113] FIGS. 19A-19C illustrates cross-sectional views of one
embodiment of a protective helmet system 1900 with a fit pod
assembly 1918 with shear or sliding properties. The protective
helmet system 1900 may comprise a helmet 1902 with an inner surface
1906 and an outer surface 1906. The helmet may further comprise an
outer layer, the outer layer having an inner surface and an outer
surface. The protective helmet system may further comprise an
impact mitigation layer, the impact mitigation layer being coupled
to the inner surface of the outer layer 1. The protective helmet
system 1900 may further comprise an inner layer, the inner layer
having an external surface and an internal surface. The external
surface of the inner layer being coupled to the impact mitigation
layer. The impact mitigation layer being disposed between the outer
layer and the inner layer. Such a protective helmet system 1900
with a fit pod assembly 1918 with shear or sliding properties
allows for helmet fit adjustment for different wearer's and creates
a shear sliding capability between the head and the outer surface
of the helmet to mitigate some of the rotational, tangential forces
that may be present during an impact. A plurality of fit pod
assemblies 1918 may be disposed within the helmet 1900.
[0114] The fit pod assembly 1918 may comprise a fit pod, a low
friction layer 1910 and a connection mechanism 1908 and an
elastomeric support mechanism 1910. The connection mechanism 1908
will be used as a retention mechanism for the fit pod assembly 1918
to be attached or coupled firmly to an inner surface of the helmet.
The connection mechanism 1908 will have features that make it
removable from the inner surface of the helmet to be replaced by
another pod for enhanced or improved fit to the wearer--different
thicknesses, shapes may be used for "mix-and-match." The connection
mechanism 1908 may be a detent snap, screw, hook and loop, and/or
any other fastener known in the art.
[0115] The low friction layer 1912 may be coupled to the fit pod.
The low friction layer 1912 allows the connection mechanism 1908 to
slide freely on a surface of the fit pod with minimal friction. The
coefficient of friction between the low friction layer 1912 and the
connection mechanism 1908 may be adjusted to allow desired shear
sliding tailored for specific impact forces. The elastomeric
support mechanism 1910 links the fit pod to the connection
mechanism 1808. The elastomeric support mechanism 1910 may be
adjusted in stiffness to allow the fit pod assembly 1918 to slide
in shear when desired during an impact to the helmet (see FIG.
19B). The elastomeric support mechanism 1910 stretches and/or
articulates to allow the shear sliding during impact and then
returns the fit pod to the original, neutral location after impact.
(see FIG. 19C) The elastomeric support mechanism 1910 may comprise
an elastomeric polymer, a woven elastomeric fabric, a spring
mechanism, and/or any combination thereof. At least a portion of
the elastomeric support system 1910 is coupled to at least a
portion of the low friction layer 1912.
[0116] The fit pods may comprise a first foam layer 1914 and a
second foam layer 1916. The first 1914 and second foam layers 1916
may comprise different foam materials and/or the same foam
materials. The first foam layer 1914 and the second foam layer 1916
may have properties for both comfort and impact mitigation.
Alternatively, the fit pod may comprise at least one foam layer,
the at least one foam layer may be a single foam material, or
multi-layered construction. The at least one foam layer, the first
foam layer 1914 and/or the second foam layer 1916 may comprise foam
material that is designed to collapse, fold, deform and/or buckle
when pressure or impacts are applied. The at least one foam
material layer, the first foam layer 1914 and/or the second foam
layer 1916 thickness can be adjusted to optimize the fit for the
wearer.
[0117] FIGS. 20A and 20B depict exemplary embodiments of a
plurality of modular fit pods and/or fit pod assemblies 2004
coupled to an inner surface of a helmet 2002 in various desired
positions. The helmet 2002 comprises an outer layer. The helmet
2002 may further comprise an impact mitigation layer, the impact
mitigation layer coupled to an inner surface of the outer layer.
The helmet 2002 may further comprise an inner layer, the inner
layer having an external surface and an internal surface, the inner
layer external surface coupled to a portion of the impact
mitigation layer and/or the outer layer. In one exemplary
embodiment, the plurality of fit pods or fit pod assemblies 2004
may be removably coupled to the inner layer, liner and/or helmet
outer layer. The plurality of fit pods and/or fit pod assemblies
2004 may comprise different sizes, shapes and thickness and may be
used to retrofit current commercially available helmets and/or
liners leading to a more customized helmet and/or may be standard
sizes used for a standard helmet. Standard helmet sizes may include
small, medium, large and extra-large. Each of the standard sizes
may include a plurality of modular fit pods and/or fit pod
assemblies.
[0118] For example, the standard small helmet size may comprise at
least 7 modular fit pods and/or fit pod assemblies 2004, where 6
modular fit pods and/or fit pod assemblies are removably connected
and one modular pod is fixed as shown in FIGS. 20A and 20B. In
alternative embodiments, other numbers and/or arrangements of fit
pods and/or fit pod assemblies 2004 could be provided, including
the use of more and/or less fit pods or fit pod assemblies 2004
within a given helmet 2002 and/or helmet liner. Desirably, the
different sized helmet layers would be accommodated by differently
spaced, oriented and/or positioned modular fit pods and/or fit pod
assemblies 2004 of identical length and/or height. To accommodate
differently shaped heads, one of more of the modular fit pods
and/or fit pod assemblies 2004 in a given helmet inner shell can be
replaced with a modular fit pods and/or fit pod assemblies 2004 of
similar height/length but differing thickness. With four different
thicknesses of modular fit pods and/or fit pod assemblies 2004 to
choose from, the present system allows a single helmet shell to
provide over 4000 different pad combinations. Where an exemplary
helmet system included small, medium, large and extra-large helmet
shells with 6 replaceable modular fit pods and/or fit pod
assemblies 2004 each, this system could provide over 16,000
combinations to accommodate virtually any head size and/or shape.
In at least one alternative embodiment, a helmet system could
include a small shell with 5 or 6 replaceable modular fit pods
and/or fit pod assemblies, medium and/or large shells with 6
replaceable modular fit pods and/or fit pod assemblies each, and an
XL shell with 6 or 7 replaceable modular fit pods and/or fit pod
assemblies.
[0119] In various embodiments, each helmet 2002 and/or helmet liner
size (i.e., small, medium, large and extra-large) could include at
least one non-removable fit pod and/or fit pod assemblies 2004
(i.e., the frontal pod), which can comprise a pad having a 1/2''
thickness at a central location, tapering down to 1/4'' thickness
at the offset sides. Alternatively, the frontal fit pod and/or fit
pod assembly could be removeable and/or replaceable, if desired,
including the ability to change the thicknesses of the front pods
and/or front fit pod assembly in a manner similar to those
described with the other modular fit pods and/or fit pod assembly
herein. If desired, the frontal fit pod and/or frontal fit pod
assembly could include optionally replaceable thin and/or thick
versions, including versions to accommodate unusual fit
circumstances.
[0120] If desired, the front fit pod and/or front fit pod assembly
could utilize a snap-fit connection to the shell (which could be
similar to various other modular pod connections described herein),
or the front fit pod and/or the frontal fit pod assembly could be
attached to the shell by hook and loop type fasteners and/or held
in by a cloth pouch attached to the front bumper and/or the shell
using Velcro or some other fastening mechanism. Alternatively,
other types of connection mechanisms may be utilized, which include
Velcro (hook and loop), adhesives, snaps, screws, press-fittings,
magnetic mechanisms, and/or any combination thereof.
[0121] By providing 4 modular fit pods and/or fit pod assemblies
2004 of similar height and length, in 4 different thicknesses
(i.e., 1/4'', 1/2'', 3/4'' and 1'' thicknesses), along with four
different helmet liner sizes (i.e., small, medium, large and
extra-large), the present system significantly reduces the cost and
complexity of the system and its components (although the use of
various other numbers of pod sizes and/or shell sizes is
contemplated herein, including 2 sizes and/or 5 sizes of pods
and/or shells). The modular fit pods and/or fit pod assemblies 2004
themselves can be manufactured in bulk, with each thickness change
typically requiring little or no modification to the manufacturing
and/or processing equipment, which greatly reduces the
cost-per-unit for each modular pod. Moreover, an equipment manager
would only need to stockpile four different shell sizes, along with
some modular pads of the four differing thicknesses (i.e., a small
bag of each size), which could be altered and interchanged at will
to fit each player. In a similar manner, only a few liner sizes
need be stockpiled to accommodate a wide range of players, such as
S/M and L/XL liners for the S, M, L youth helmet and one liner for
the M, L, XL varsity helmet, if desired.
[0122] If desired, the modularity of the fit pods and/or fit pod
assemblies 2004 could provide "position-specific" features for a
player wishing to provide supplemental and/or particularized
protection with one or more enhanced principal impact zones and/or
impact types that can be particularized to a specific
player-position and/or the individual behavior of a specific player
(i.e., supplemental protection from one or more directions and/or
types of impacts that may be anticipated based on the player's
position and/or type of play). For example, a player may wish to
incorporate additional impact protection into a right side of the
player's helmet, such as where the player tends to "lead with their
right" in impact situations and/or where the location of the
player's position tends to lead to a greater magnitude of right
side impacts (i.e., the right-side guard position). If desired, the
speed, direction, and magnitude of impact and/or player force could
be collected during each player activity and analyzed to tailor
impact protective elements for the specific player position.
[0123] In order to increase the amount of protection on the right
side of the helmet, the player may simply replace one or more of
the modular fit pods and/or fit pod assemblies 2004 on the right
side of the helmet 2002 and/or helmet liner with thicker fit pods
and/or fit pod assemblies 2004, which could include replacement of
modular fit pods and/or fit pod assemblies 2004 of the left helmet
side with thinner fit pods (to balance the width reduction) and/or
fit pod assemblies. Alternatively, the player may choose an
"oversized" liner and/or helmet which may be slightly "too big" for
the player, and then the player can replace the modular pods in one
or more locations with thicker fit pods (to increase the impact
absorbing layer depth and also to "fit" the helmet more
appropriately) and/or fit pod assemblies.
[0124] The one or more modular fit pod assemblies may be desirably
positioned around various locations of the wearer's head, such as
covering much of the area between an inner shell of the helmet and
the user's head. Such plurality of fit pod assemblies may include
one or more of the following: a frontal assembly (or front), a
crown assembly, an occipital assembly (or lower-back), a mid-back
assembly, a parietal assembly (or midline), and a temporal assembly
(right and/or left sides), and/or any combination(s) thereof. At
least a portion of the fit pod assemblies may be removably coupled
to at least one inner layer, impact mitigation layer, outer layer
and/or any combination thereof to facilitate energy absorption,
reduce angular motion and/or rotational motion of the wearer after
impact, enhance fit and comfort.
[0125] The fit pod and/or fit pod assemblies may be manufactured in
different ways. In one embodiment, the fit pod may comprise a top
layer, a bottom layer, and at least one foam layer. The at least
one foam layer is disposed between the top layer and bottom layer.
Disposed being "free-floating" between the top and bottom layer
and/or coupled to the top and/or bottom layer. The at least one
foam layer may comprise a first foam layer and a second foam layer.
The at least one foam layer may be a single, continuous piece of
foam material. Alternatively, the at least one foam layer may be
two or more segmented pieces of foam material. The top layer and
the bottom layer may be the same materials or may be different
materials. The top layer may be coupled to the bottom layer. The
coupling may include adhesive, Velcro, ultrasonic or impulse
welding, stitching, heat sealing, heat or hot melt, vacuumed
formed, thermoformed, and/or any combination thereof.
[0126] Comfort Liner Assemblies
[0127] FIG. 21A-21C depicts one exemplary embodiment of an
improved, one-piece comfort liner 2100, which can be utilized in
conjunction with the various embodiments described herein. In this
embodiment, the comfort liner 2100 can wrap around the wearer's
head and fit within an inner layer and/or an interior surface of a
helmet which can desirably improve the comfort and fit of the
helmet system on the player or wearer. The comfort liner 2100 may
comprise a plurality of comfort liner pads 2104, at least one base
layer 2110, and a plurality of fit tabs 2102. The plurality of
comfort liner pads 2104 can be positioned and/or coupled onto the
at least one base layer 2110, where each of the plurality of
comfort pads 2104 are positioned adjacent to each other with a gap
distance 2112. The gap distance 2114 may be between 2 mm to 20 mm,
which the gap distance 2114 facilitates flexibility when conforming
to a player's or wearer's head. Each of the plurality of comfort
pads 2104 may be placed in specific regions within the helmet, such
as at least one frontal region (or front), an occipital region (or
lower-back), a mid-back region, a parietal region (or midline), and
a temporal region (right and/or left sides), and/or any
combination(s) thereof. The fit tabs 2102 may be integrated with
the at least one base layer 2110, and/or may be a separate piece
that is coupled to the at least one base layer 2110. The plurality
of comfort pads 2104 may further include temple pads 2106 (on left
and right sides). The fit tabs 2102 are connection mechanisms are
desirably placed around the perimeter of the comfort liner to help
with securement of the comfort liner to itself and/or the helmet.
The plurality of comfort pads 2104 may be coupled onto the at least
one base layer 2110 leaving an edge or flange 2114. The edge or
flange may have a width of 2 mm to 20 mm. alternatively, the
comfort liner 2100 may be separated into two or more pieces. For
example, the comfort liner 2100 may be separated into front portion
and a back portion and may be segmented along an axis 2108.
[0128] FIG. 21C depicts a cross-sectional view of one exemplary
embodiment of a comfort pad 2104 coupled onto the at least one base
layer 2110. The comfort pad may comprise at least one foam layer
2116 and a top layer 2118. The top layer 2118 and the at least one
foam layer 2116 may utilize different materials or the same
materials. The top layer 2118 may be an flexible material, an
elastic material, a plastic or fabric identification label layer,
an over-layer of soft leather, a felt or a similar polymer (i.e., a
skin contact layer), an adhesive layer, a foam material (i.e.,
Confor slow recovery CF 47 medium foam commercially available from
the Aero Technologies division of 3M Corporation, St. Paul, Minn.
USA--and/or other open-cell polyurethane foam such as 4.0 Custula
open cell foam), a layer of perforated and/or non-perforated impact
resistant polymer foam 1825 (i.e., Poron XRD urethane based
polymer--commercially available from Rogers Corporation of Rogers,
Conn., USA), an under-layer of adhesive, a flexible rubber sealant
layer or fabric backing (not shown) which may optionally be sealed
and/or unsealed, an optional elastic connector layer, an optional
plastic or fabric identification label layer and an optional cast
substrate connector layer, if desired. Furthermore, the comfort pad
2104 may further comprise an impact mitigation layer and/or
structure (not shown). In a similar manner, the remaining
components of the pods and/or liner assemblies could include
comfort or impact absorbing pads and/or other structures
incorporating a similar combination and/or arrangement of materials
and/or other materials, if desired. The comfort pad 2104 may have a
desired thickness 2120, the thickness can range from 5 mm to 20 mm.
FIGS. 22A-22B illustrate an alternate embodiment of a comfort
liner.
[0129] FIG. 23 depicts a front view of another alternate embodiment
of a comfort liner 2300. The comfort liner 2300 may comprise a
plurality of comfort liner pads 2304, at least one base layer 2306,
and a plurality of fit tabs 2302. The plurality of comfort liner
pads 2304 can be positioned and/or coupled onto the at least one
