BACKGROUND
[0002] Helmets that provide a wearer with impact protection are
recommended when riding a motorcycle or bicycle as well as when
participating in certain recreational sports, such as, but not
limited to, rock climbing and skiing. Helmets that provide for
impact and/or ballistic protection tend to be one or more of
uncomfortable, hot, heavy and visually unappealing. Because of the
foregoing, many participants in the aforementioned activities do
not wear a helmet increasing their risk of head injury in an
accident.
[0003] While helmets are generally unpopular with wearers and those
who eschew helmets alike (even helmet wearers would not wear a
helmet but for the safety considerations), caps and hats of
differing styles are regularly worn by the general population. For
instance, baseball caps and beanies are extremely popular among
certain segments of the population. Both types of hats are
comprised primarily of fabric that is flexible and soft. Fabric
headgear offers essentially no impact or ballistic protection to a
wearer. Rather, one of the primary purposes of wearing these types
of headgear is style and/or fashion.

DETAILED DESCRIPTION
[0025] Broadly, at least one embodiment of the invention comprises
a close fitting shell which may be worn directly over the head. Due
to the design of the shell, a wearer may cover the shell with a
cap, beanie, bandanna or any other type of headgear. The shell may
be comprised of fabric that incorporates a plurality of separate
rigid or semi-rigid panels therein. The fabric portion of the shell
may comprise a plurality of distributed pockets sized and
configured to receive specific inserts or panels. In some
embodiments, the shell may implement a chin strap to aid in
securing the shell to a wearer's head. It is to be appreciated that
variations of the chin strap may be implemented with the shell.
[0026] Another embodiment of the present invention may comprise a
fabric or soft-sided headgear, such as a cap or beanie, which may
incorporate a plurality of separate rigid or semi-rigid panels
therein. Collectively, the panels may cover a significant portion
of a surface area of a wearer's head located within the piece of
headgear. Further, the design may permit the headgear to be worn
close to the head in a form fitting manner closer in appearance to
a prior art cap or beanie when contrasted with a rigid helmet.
[0027] Embodiments of the present invention may be implemented as
soft helmets that provide enhanced protection for a wearer when
compared to soft caps and hats. For purposes of this description, a
soft helmet refers to a protective headgear that may retain a
degree of flexibility such as is provided by the fabric, but may
also provide a measure of ballistic and impact protection for the
portions of the head located underneath the protective panels.
[0028] Embodiments of the soft helmet may be used in a variety of
situations depending on the nature of the panels used. The
individual panels may comprise any suitable material, and in
several embodiments are removable and interchangeable. In one
instance, such as motorcycling and especially by people who would
not otherwise wear a helmet, the soft helmet may incorporate panels
having a rigid outer layer and energy absorbing inner layer. The
soft helmet may also be used by skiers, rock climbers, snow
boarders, bicyclists or any other activity where protection of the
head from impact is important.
[0029] The soft inner layer may vary depending on the intended use.
For instance, variations of the panels may include an energy
absorbing layer that absorbs and dissipates energy of an impact
much in the same fashion as expanded polystyrene does in
motorcycle, skiing and bicycling helmets. In other variations of
the soft helmet, the panels may be made as thin and/or light as
possible while still providing a reasonable measure of protection.
Some panel configurations are contemplated wherein both the inner
and outer layers are made of a soft material, such as an elastomer,
but of differing hardness. Soft helmets having thin lightweight
panels and those with soft panels may be useful in medical
applications with children and/or adults who, for instance, have to
wear protection to protect their heads because of soft spots in the
skull either from surgery or a medical condition.
[0030] EMbodiments of the soft helmet are illustrated in the
figures. A description describing elements of the various
embodiments is provided with the description of the figures. As can
be appreciated, the description provided in relation to a
particular figure is not necessarily limited to the embodiment(s)
shown in the particular figure, but may be applicable to other
embodiments as well.

[0039] A First Embodiment of a Soft helmet for Wear Under a Hat
[0040] FIG. 1A is a detailed diagram of an embodiment 100 showing a
soft helmet implemented as a shell 102. Embodiment 100 is one
example of a shell used for protection while participating in
recreational sports.
[0041] The shell 102 may have an exterior layer 104, an interior
layer 106, a plurality of pockets 108, and a plurality of panels or
inserts 110.
[0042] The shell 102 may be made of any suitable fabric including,
but not limited to, lycra or spandex stretchable fabric, nylon,
cotton, or any other similar material. Generally, the exterior
layer 104 and the interior layer 106 are comprised of the same
material. For instance, the exterior layer 104 and interior layer
106 may be made out of a knit fabric, such as cotton. In one
instance, the exterior layer 104 may be made of a different
material from the interior layer 106. For example, the exterior
layer 104 may comprise a fire retardant material and the interior
layer 106 may comprise a breathable mesh material.
[0043] To protect the skull of a wearer using the shell 102, the
plurality of panels 110 may be configured to fit within the
plurality of pockets 108. Each pocket of the plurality of pockets
108 may have an open end. The open end of the pocket may be
configured to receive a panel. In some embodiments, a hook and loop
closure may be provided at the opening of each pocket to secure the
panels therein. It is to be appreciated that a variety of means to
secure the panels may be implemented. For example, snap fasteners
may be implemented to secure panels within the pockets. In one
instance, multiple types of closure means may be used. For example,
some pockets may implement a snap fastener and other pockets may
implement a hook and loop closure.
[0044] In a typical construction, a small number of larger pieces
of fabric may be joined to define the general shape of the outer
layer 104 of the shell 102 and smaller pieces of fabric may be sewn
to the joined larger pieces to make the pockets 108 configured to
receive the various panels 110. The open ends of the smaller pieces
may be folded over proximate their open ends to form an enclosure,
as shown in Figure I B. Accordingly, the ends of the panels 110 may
be placed in the folded over portion when placed in the pockets 108
thereby minimizing the chance that a panel will slide out of a
pocket at the open end. In other variations, hook and loop
closures, snaps, buttons or other means of sealing the open end may
be provided.
[0045] As can be appreciated, the actual means for attaching the
panels 110 to the interior layer 106 of the shell 102 can vary
dramatically between embodiments as can the design and
configuration of the panels 110.
[0046] In a preferred embodiment of the shell 102, the plurality of
pockets 108 may be segmented. By segmenting the pockets, a majority
of a wearer's skull may be covered by the pockets 108. Generally
the plurality of pockets 108 may be spaced equidistant from each
other.
[0047] In another instance, the plurality of pockets 108 may be
placed based on the intended use of the shell 102. For example, if
the shell 102 is used for rock climbing, more of the pockets may be
placed towards the crown of the shell. By placing more pockets
towards the crown, more protection may be afforded the top of the
skull of a user. This may be advantageous in rock climbing where
falling rocks are a concern.
[0048] Since the shell 102 may be implemented in a variety of
recreational activities, the panels 110 need to be adaptable for a
variety of uses. Generally, the panels 110 are comprised of two
different materials coupled together. In one embodiment, the panels
110 may include a hard or rigid top portion/layer and a soft or
compressible bottom portion/layer. The top portion may be comprised
of a rigid polymeric material, such as nylon. As can be appreciated
by one of ordinary skill in the art, the type and strength of the
rigid portion will greatly affect the puncture resistance of the
panel as well as the panel's ability to transfer impact or
ballistic loads over the area of the panel. The bottom portion or
layer may be comprised of a soft, resilient or compressible
material. The bottom portion may provide impact energy absorption.
Numerous materials may be used to form the bottom layer as would be
obvious to one of ordinary skill in the art given the benefit of
this disclosure.
[0049] In a preferred embodiment, one side of the panel may be made
of a rigid material and the other side may be made of an impact
absorbing material. It is to be appreciated that the two materials
may be coupled in a variety of manners, which depends on the
materials implemented. For example, overmolding may be implemented
to couple two materials together into one panel.
[0050] Of note, in an actual shell the panels 110 may not be
readily visible to an observer. The panels 110 are visible in the
figures for illustrative purposes only.
[0051] As can be appreciated, the shape of the panels 110 may be
largely dictated by where on the shell 102 the panel is to reside.
Further, depending on the intended use of the shell 102, the number
of pockets 108 may be altered to provide more or less panels. The
user may also alter the amount of protection by removing panels
and/or changing out different types of panels
[0052] Of note, because the panels are removable, variations of the
shell 102 are contemplated wherein the type of panel may be
switched out depending on the type of activity being undertaken
and/or the amount of head protection desired. For instance, if the
shell 102 is being worn casually, the panels 110 may be removed
completely with the user donning the shell 102 alone.
Alternatively, when the shell 102 is used for motorcycling, a rigid
panel with a relatively thick impact energy absorption layer may be
placed in the pockets 108 of the shell 102. In contrast, if the
shell 102 is to be worn while rock climbing, impact protection from
small rocks falling from overhead might be most important. As such,
panels with thicker or more puncture resistant rigid layers might
be specified rather than bottom layers comprised of foam or perhaps
a layer of leather.
[0053] Where no protection is needed, a user may remove all of the
panels 110 from the shell 102. For instance, when in transit to the
ski resort a user may remove all the panels 110. Once the user is
ready to ski or snowboard, the user may place the panels 110 back
into the pockets 108. The user may also remove all the panels after
they are done skiing. The shell 102 may provide a protective
headgear when needed and also provide a practical everyday cap to
wear when no protection is needed.
[0054] . Some embodiments may incorporate a strap (not shown in
FIG. 1A). The strap may act to secure the shell 102 to a wearer's
head. Typically, the chin strap may be thin enough to be tucked
under the shell 102 between the wearer's head and the interior
layer 106 of the shell 102 when not in use. The chin strap is
provided primarily for use when undertaking a recreational activity
wherein an impact could dislodge the shell 102 from the wearer. As
such, the chin strap may act to help hold the shell 102 in place
during an impact event. In one embodiment, the chin strap may
comprise a single point of attachment on the left side and the
right side of the shell 102. Typically, the chin strap is attached
at a location in front of the ears of the wearer when in use. It is
to be appreciated that a two point attachment may be implemented.
The choice of which strap to use will depend on the particulars of
the design and the type of protection the shell 102 is designed to
provide.
[0055] In the illustrated embodiments, the shell 102 comprises a
beanie of the head hugging form fitting type. This type of shell is
soft-sided meaning that there is very little if any at all rigid or
semi-rigid support members incorporated into the shell 102 itself
and that the shell 102, absent the panels 110, may generally
conform to the shape of a wearer's head, if not immediately upon
donning the shell 102, over time.
[0056] , Differences in the shell 102 compared to prior art
headgear are confined largely to the interior portions of the
headgear. The shell 102 may include an inside liner segmented into
pockets as described above. In other embodiments separate and
distinct pocket modules may be sewn or otherwise attached to the
interior surface of a single layer fabric shell or they may be
secured to a continuous liner. In another embodiment, the liner may
comprise a loop fabric substitute that extends over all or select
portions of the shell's interior surface. The corresponding rigid
panels can have hoop material secured to the outside surface of the
rigid portion such that the panels can be affixed to the liner at
wearer desired or predetermined locations. In yet another
embodiment, the rigid panels may not be removable from the shell.
Rather, they may be permanently attached to the shell by way of an
adhesive, closed pockets, sewing or mechanical fasteners, such as
rivets.
[0057] Referring to FIGS. 2A-2B, a detailed diagram of a panel 200
is shown. FIG. 2A is a top view of the panel 200 and FIG. 2B is a
side view of the panel 200. The panel 200 may be one embodiment of
a panel such as one of the plurality of panels 110 that may be
implemented in the shell 102 shown in FIG. 1 A. The panel 200 may
be used to provide protection for the head of a wearer.
[0058] FIG. 2A shows a top view of the panel 200. As shown, the
panel 200 may have a predominately rectangular shape. The size of
the panel 200 may be altered depending on a use of the panel 200.
It is also to be appreciated that the panel 200 may be sized based
on the size of a wearer's head. For instance, the shell 102 may be
custom fitted to an individual wearer based on the size of the
rectangular panel 200. In one example, the panel 200 may be two and
a half inches long by one and a quarter inch wide. It is to be
appreciated that varying sizes of the panel 200 may be implemented.
For instance, a smaller rectangular panel may be used around the
crown of a wearer's head and a larger rectangular shell may be used
around the back and sides of the wearer's head.
[0059] The panel 200 may include a slot 202. In a preferred
embodiment the panel 200 may have three slots. The slots 202 may
reduce weight and provide ventilation. The size and number of slots
202 may be altered based on an intended use of the shell. It is
noted that a variety of number of slots and slot sizes may be
implemented. The number of slots may coordinate with the size of
the slots. For instance, a small number of large slots or a large
number of small slots may be implemented.
[0060] FIG. 2B is a side view of the panel 200. Generally, the
panel 200 may comprise an outer or top portion 204 and an inner or
bottom portion 206. In one embodiment, the outer portion 204 and
the inner portion 206 may comprise different materials. For
example, the outer portion may be a rigid outer layer that is about
an eighth of an inch thick and the inner portion 206 may be an
elastomeric inner layer that is about three sixteenths of an inch
thick. It is to be appreciated that varying thicknesses of the
outer portion 204 and inner portion 206 are contemplated.
[0061] As shown in FIG. 2B, the panel 200 may be curved to match
the curvature of a head on which the shell 102 is to be worn. It is
to be appreciated that different curvatures may be used depending
on the needs of a wearer.
[0062] In fabrication, the outer portion 204 and inner portion 206
may be made and joined in any suitable manner. In one variation,
the rigid panel portion 204 may be injection molded. An overmolding
process may be used to join the elastomeric layer 206 to the rigid
layer 204. In other variations, the two pieces may be adhesively
joined or fused together. As can be appreciated, the sizes,
thicknesses, materials and configuration of the panel 200 may
vary.
[0063] The overmolding process involves the use of two separate
materials to form one cohesive end product. One type of overmolding
is insert overmolding. Insert overmolding involves an injection
molding process where one material, usually an elastomeric, is
molded "over" a secondary substrate material, usually a rigid
plastic. In one embodiment of the panel 200, the inner portion 206
may be molded over the outer portion 204.
[0064] The outer portion 204 may be comprised of a rigid polymeric
material, such as nylon, that may or may not be reinforced, such as
with Kevlar, carbon or glass fibers. In other variations, the rigid
portion 204 may comprise a continuous fiber composite material
wherein the fibers are made of one or a combination of spectra,
Kevlar, carbon or glass fibers or equivalents thereof in a suitable
matrix material, such as epoxy. In yet other variations, the rigid
portion 204 may comprise a metallic material, such as an aluminum
or magnesium alloy. As can be appreciated by one of ordinary skill
in the art, the type and strength of the rigid portion 204 will
greatly affect the puncture resistance of the panel as well as the
panel's ability to transfer impact or ballistic loads over the area
of the panel.
[0065] The inner portion 206 may be comprised of a soft, resilient
or compressible material. Generally, the inner portion 206 may be
configured to perform one or more functions including, but not
limited to, providing impact energy absorption, making the shell
102 more comfortable, and/or acting as an interface between the
hard and rigid portion of the panel and the head of the wearer. In
one embodiment, the inner portion 206 may comprise an energy
absorbing material, such as expanded polystyrene, that compresses
upon impact dissipating, at least partially, the energy of the
impact transferred to a wearer's head.
[0066] In other embodiments, the inner portion 206 may comprise
compressible and resilient open or closed cell foam that acts
primarily to provide the wearer comfort. Implementing foam may also
ensure a more uniform fit of the shell 102. A polymeric gel
material may also be used to facilitate greater comfort while also
providing some impact energy absorption and dissipation properties.
Numerous other materials may be used to form the inner portion 206
aside from those listed as would be obvious to one of ordinary
skill in the art given the benefit of this disclosure.
[0067] Referring to FIGS. 3A-3B, a detailed diagram of a panel 300
is shown. FIG. 3A is a top view of the panel 300 and FIG. 3B is a
side view of the panel 300. The panel 300 may be one embodiment of
a panel such as one of the plurality of panels 110 that may be
implemented in the shell 102 shown in FIG. 1A.
[0068] As shown, the panel 300 may have a predominately triangular
shape. The size of the triangular panel 300 may be altered
depending on a use of the panel 300. It is to be appreciated that
the panel 300 may be sized based on the size of a wearer's head.
The shell 102 may be custom fitted to an individual wearer based on
the size of the triangular panel 300. In one example, the panel 300
may be three and three fourths of an inch by three and one thirty
seconds of an inch. It is to be appreciated that varying sizes of
the panel 300 may be implemented. For instance, a smaller
triangular panel may be used around the crown of a wearer's head
and a larger triangular shell may be used around the back and sides
of the wearer's head.
[0069] The panel 300 may include a slot 302 similar to the panel
200. As shown, in a preferred embodiment the panel 300 may have
three slots. The slots 302 may reduce weight and provide
ventilation. The size and number of slots 302 may be altered based
on an intended use of the shell. It is noted that a variety of
number of slots and slot sizes may be implemented.
[0070] FIG. 3B is a side view of the panel 300. As shown in FIG.
3B, the panel 300 may be curved to match the curvature of a head on
which the shell is to be worn. It is appreciated that different
curvatures may be used depending on the needs of a wearer.
[0071] The manufacture of the panel 300 may be similar to the
manufacture of the panel 200. The panel 300 may comprise an outer
portion 304 and an inner portion 306. The outer portion 304 may be
a rigid material and the inner portion 306 may be a compressible or
energy absorbing material as previously described.
[0072] A Second Embodiment of a Soft Helmet Having Protective
Panels Attached Thereto
[0073] FIG. 4 is a diagram of an embodiment 400 showing a soft
helmet 402. The embodiment 400 is a second embodiment of a soft
helmet for use in recreational activities. As shown, the soft
helmet 402 may appear to be a normal beanie cap. The soft helmet
402 may also appear to be a baseball cap, as is shown in FIG.
5.
[0074] The beanie 402 generally comprises an outer layer 404 and an
inner layer 406. The outer layer 404 and inner layer 406 may be
comprised of different materials. For example, the outer layer 404
may be made of a fire resistant fabric while the inner layer 406 is
made of an elastic fabric. In one instance, the outer layer 404 and
inner layer 406 may be comprised of the same material, such as a
knit fabric. It is to be appreciated that several different types
of fabrics and combinations of fabrics may be implemented in the
embodiment 400 of the present invention.
[0075] The inner layer 406 of the beanie 402 may be segmented into
a plurality of pockets 408. FIG. 4 shows one example of the general
placement of the pockets 408 in the beanie 402. The actual
placement'of the pockets 408 may vary significantly depending on
the particular design of an embodiment and on which recreational
activity the beanie 402 is intended to be used for. Generally, the
pockets 408 are placed to cover a majority of the beanie 402 and a
wearer's head.
[0076] To provide protection, the beanie 402 may implement a
plurality of panels 410. The panels 410 may be similar in design
and shape to the panels described previously in reference to FIGS.
1-3B. The panels 410 may be configured to fit within the pockets
408. It is to be appreciated that a variety of means for securing
the panels 410 within the pockets 408 may be implemented. For
example, a hook and loop closure may be used. In another example,
snap fasteners may be used to secure the panels 410 in the pockets
408.
[0077] Each of the panels 410 may comprise an outer portion and an
inner portion. The outer portion may be a hard or rigid top
portion/layer and the inner portion may be a soft or compressible
bottom portion/layer.
[0078] The outer portion may be comprised of a rigid polymeric
material, such as nylon, that may or may not be reinforced, such as
with Kevlar, carbon or glass fibers. In other variations, the rigid
portion may comprise a continuous fiber composite material wherein
the fibers are made of one or a combination of spectra, Kevlar,
carbon or glass fibers or equivalents thereof in a suitable matrix
material, such as epoxy. In yet other variations, the rigid portion
may comprise a metallic material, such as an aluminum or magnesium
alloy. As can be appreciated by one of ordinary skill in the art,
the type and strength of the rigid portion may greatly affect the
puncture resistance of the panel as well as the ability of the
panel to transfer impact or ballistic loads over the area of the
panel.
[0079] The inner portion of the panels 410 may be comprised of a
soft, resilient or compressible material. The inner portion may be
configured to provide impact energy absorption, make the beanie 402
more comfortable, and act as an interface between the rigid portion
of the panel and the head of a wearer. The inner portion may
comprise an energy absorbing material, such as expanded
polystyrene, that compresses upon impact dissipating at least
partially the energy of the impact transferred to a wearer's head.
In other embodiments, the inner portion may comprise compressible
and resilient open or closed cell foam that acts primarily to
provide the wearer comfort as well as ensure a more uniform fit of
the beanie 402. A polymeric gel material may also be used to
facilitate greater comfort while also providing some impact energy
absorption and dissipation properties. Numerous other materials may
be used to form the inner portion aside from those listed as would
be obvious to one of ordinary skill in the art given the benefit of
this disclosure.
[0080] As can be appreciated, the shape of the panels 410 may
largely be dictated by where on the beanie 402 the panel is to
reside. As shown in FIG. 4,.one or more of the panels 410 may have
a rectangular shape and another one or more of the panels 410 may
have a triangular shape. It is to be appreciated that other shapes
for the panels may be implemented. For instance, a clover shaped
panel may be placed near the crown of the beanie 402. In another
instance, a circular shaped panel may be used near the crown of the
beanie 402. In one embodiment, the shell 402 may have six pockets
configured to receive triangular shaped panels and sixteen pockets
configured to receive rectangular panels.
[0081] The beanie 402 may also incorporate a chin strap 412.
Generally, the strap 412 may be a chin strap. The chin strap 412
may comprise an attachment section 414 and an elastic section 416.
In one embodiment, the attachment section 414 and elastic section
416 may comprise the same material. In another embodiment, the
attachment section 414 and the elastic section 416 may comprise
different materials. For example, the attachment section 414 may
comprise a nylon webbing and the elastic section 416 may comprise
spandex.
[0082] Typically, the chin strap 412 may be thin enough to be
tucked under the beanie 402 between the wearer's head and the
inside surface 406 of the beanie 402 when not in use. The chin
strap 412 is provided primarily for use when undertaking a
recreational activity wherein an impact could dislodge the headgear
from the wearer. The chin strap 412 may act to help hold the beanie
402 in place during an impact event.
[0083] The attachment section 414 of the chin strap 412, as
illustrated, may comprise two attachment points on each side of the
beanie 402. In this embodiment, the chin strap 412 may attach in
front of the ear and behind the ear on each side of the beanie 402.
This type of strap attachment may be more secure than a single
strap attachment, but may add more bulk underneath the cap when the
strap is stowed and not in use.
[0084] The chin strap 412 may also be implemented with single point
of attachment on each side of the beanie 402. In one instance, the
point of attachment may be located behind the ear. In another
instance, the point of attachment may be located in front of the or
on top of the ear. It is to be appreciated that the location of the
point of attachment may be altered depending on the use of the
beanie 402. The choice of which strap to use will depend on the
particulars of the design and the type of protection the cap is
designed to provide.
[0085] The elastic section 416 may expand and contract to securely
fit around the chin of a user. The elastic section 416 may be in
place of other means to adjust the length of a chin strap or in
addition to other means, such as buckles.
[0086] In one embodiment, the chin strap 412 may comprise two
separate sections. The chin strap 412 may have a left strap and a
right strap. The left strap and the right strap may be configured
to be connected. No specific type of latch mechanism to join the
left and right chin straps together is specified. It is to be
appreciated that any suitable latching system may be employed.
Because the strap in certain embodiment can be stowed in the
headgear when not in use, a relatively thin attachment mechanism is
desirable to both increase wearer comfort when the mechanism is
stowed as well as limit its effect on the visual aesthetics of the
headgear. In at least one embodiment, the chin strap attachment
mechanism may simply comprise corresponding sections of hook and
loop material as illustrated in FIG. 9C.
[0087] In one embodiment, the strap 412 may comprise a webbing
material that is attached to the beanie 402 approximately one inch
or so above the bottom rim thereof. As shown, the strap 412 may be
sewn in place, but the strap 412 may also be connected to the
beanie 402 by other suitable means. Such means may include rivets
or other mechanical fasteners. In another embodiment, the strap 412
may be secured to a corresponding rigid panel, which may be stored
in a pocket of the beanie 402.
[0088] One of the aforementioned key features of the strap 412 is
the ability to tuck the strap into the headgear. The strap 412 may
then not be visible or exposed when the strap 412 is not needed.
Connective means may be provided at the top of the beanie 402 to
secure the strap 412 in a stowed position. In one embodiment, the
strap 412 may comprise a hook and loop to secure the strap 412 in
place. In other embodiments, varying securing mechanisms are
contemplated as well.
[0089] FIG. 5 is a diagram of an embodiment 500 showing a soft
helmet 502. As shown, the soft helmet 502 may appear to look like a
baseball cap. The baseball cap 502 may have a similar internal
design as the beanie 402 previously disclosed. The baseball cap 502
may include a brim 504. Brims of the baseball cap variety are
typically reinforced with a cardboard or thin plastic sheet that
provides rigidity thereto.
[0090] The baseball cap 502 may be made of a fabric material that
is flexible and resilient. As can be appreciated, the construction
of the baseball cap 502, at least as it relates to its outward
appearance, is similar to corresponding prior art baseball caps
that do not include rigid reinforcement panels.
[0091] The baseball cap 502 may have a plurality of pockets 506
configured to receive a plurality of protective panels 508. The
protective panels 508 may be configured similar to the plurality of
panels 110 and plurality of panels 410 previously discussed. The
baseball cap 502 may provide similar protection as the beanie 402,
albeit with a different look.
[0092] FIGS. 6A and 6B show an embodiment 600 with one possible
configuration of a plurality of panels. For sake of illustration,
the plurality of panels are shown without a fabric headgear or
shell. FIG. 6A is a front view of the configuration of panels and
FIG. 6B is a side view of the configuration.
[0093] As illustrated in FIGS. 6A and 6B, a set of generally
arcuate triangular panels cover the top of the head and a series of
arcuate rectangular panels encircle the forehead, sides and back of
the head above the ears. The panels may be made with a rigid top
portion and an energy absorbing bottom portion. A total of 12
panels are utilized, although similar variations with a different
number of panels are contemplated.
[0094] FIGS. 7A-7C show an embodiment 700 with another possible
configuration of a plurality of panels. For sake of illustration,
the plurality of panels are shown without a fabric headgear or
shell. FIGS. 7A-7C show a front, side, and back view, respectively,
of the configuration of panels on a wearer's head.
[0095] As illustrated in FIGS. 7A-7C, a set of about 22 panels are
implemented including a large plurality of rectangular panels that
extend from the forehead over the top of the head to the nape of
the neck, several generally triangular portions to protect the side
of the head above the ears, and several generally rectangular
pieces below the triangular pieces on the back side of the
head.
[0096] It is to be appreciated and understood that a variety of
different configurations may be implemented in the present
invention. The number and placement of panels may depend on various
factors including, but not limited to, the amount of protection
needed, the recreational activity a wearer is participating in,
and/or the size of a wearer's head.
[0097] FIGS. 8A-8B illustrate an embodiment 800 of a soft helmet
802 with a chin strap 804. The chin strap 804 is shown deployed in
FIG. 8A. In FIG. 8B, the chin strap 804 is shown tucked inside the
soft helmet 802. The chin strap 804 may be attached to the interior
of the headgear 802 by a variety of means. For instance, the
headgear 802 and the chin strap 804 may implement a hook and loop
closure 806. In another instance, the headgear 802 and the chin
strap 804 may implement a fastener. It is to be appreciated that a
variety of means for securing the chin strap 804 to the soft helmet
802 may be implemented.
[0098] FIGS. 9A-9F illustrate an embodiment 900 with varying types
of chin straps that may be implemented with the present
invention.
[0099] FIG. 9A is a side view of a soft helmet with a quick release
chin strap. Further, as shown in FIG. 9A, in some embodiments the
chin strap may have two attachment points to the soft helmet. This
type of chin strap may be utilized for extreme recreational
activities, such as motorcycling and rock climbing.
[0100] FIG. 9B is a side view of a soft helmet with a quick release
chin strap that has one attachment point. This type of chin strap
may be utilized while participating in medium recreational
activities. For instance, a bike rider or rollerblader may be
inclined to us this type of chin strap.
[0101] FIG. 9C is a front view of a soft helmet with a hook and
loop chin strap. FIG. 9D is a front view of a soft helmet with a
chin strap that has a means for tightening the chin strap. As
shown, the chin strap is attached to the interior of the soft
helmet.
[0102] FIG. 9E is a front view of a soft helmet with a belt buckle
chin strap. FIG. 9F is a front view of a soft helmet with an
adjustable chin strap. It is to be appreciated that each of the
aforementioned chin straps may have one or two attachment
points.
[0103] Ultimately, it is appreciated that the design of the shell
102 and beanie 402 can vary dramatically in terms of construction
and construction materials. Further, although the styles of
headgear primarily discussed herein are caps and beanies, the soft
helmet can be of any suitable style. Further, the use of a liner to
form pockets or otherwise facilitate the attachment of the rigid
panels can vary wherein some designs dispense with a liner
altogether by providing a means to attach the panels directly to a
first or outer layer of the shell. The outer layer of the shell 102
and the beanie 402 as primarily discussed above comprises fabric,
but other embodiments can comprise flexible resilient sheet
material that is not a fabric, such as a durable paper product or
thin elastomeric polymeric sheet. Several means of attaching the
rigid panels are indicated above but the disclosure should not be
considered limited to just the proffered types of attachments.
Other means are contemplated as well including, but not limited to,
pockets on the exterior surface of the headgear and clips or snaps
on the inside of the shell to secure the panels.
Alternative Embodiments and Variations
[0104] The various embodiments and variations thereof, illustrated
in the accompanying Figures and/or described above, are merely
exemplary and are not meant to limit the scope of the invention. It
is to be appreciated that numerous other variations of the
invention have been contemplated, as would be obvious to one of
ordinary skill in the art, given the benefit of this disclosure.
All variations of the invention that read upon appended claims are
intended and contemplated to be within the scope of the
invention.
