Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] The invention claims the benefit of and priority to U.S.
Provisional Application No. 60/389074 filed Jun. 14, 2002 and
entitled Helmet Chinstrap.
BACKGROUND OF INVENTION
[0002] 1. Field of Use
[0003] The invention subject of this specification is an improved
chinstrap for use with protective headgear, including helmets used
in sports, industry or military applications. The invention
provides improved protection for the user's face, chin and jaw, as
well as improves comfort and performance of other portions of the
head protection device, hereinafter "helmet."
[0004] 2. Summary of Related Technology
[0005] Helmets are used in a variety of activities and styles. It
is often useful to secure the helmet on the user's head for obvious
convenience and to improve performance. Some methods of securing a
helmet have been a loosely worn strap under the user's chin. Other
methods have be a more tightly worn strap across the front of the
jaw. Other variations have utilized a strap that covers both the
front and bottom portion of the jaw, with the goal to hold the
helmet more tightly to the user's head, and maintain the helmet in
a more fixed position upon the user, thus enhancing the protective
aspects of the helmet and, hopefully the user's comfort. More
recently, the chinstraps have been adapted to provide additional
protection to the user, independent of simply holding the helmet on
the user's head.
SUMMARY OF INVENTION
[0006] Protective helmets are of course well known. Also, securing
the helmet to the user's head with a chinstrap is also well known.
However, changes in helmet styles and materials have resulted in a
variety of differing attachment configurations. Also, the
applications or activities in which helmets are worn has also
changed and expanded as result of new technology, occupational
activities and sports activities. Increasing emphasis on personal
safety and protection, in both work and sports activities has
accelerated the change in helmet design and use.
[0007] It is therefore a goal of the invention to provide a
chinstrap that improves user comfort.
[0008] It is a further goal of the invention to improve the
protection provided by the helmet.
[0009] It is yet another goal to provide improved protection to the
face, chin and jaw of each user.
[0010] It is still yet another goal to provide a chinstrap that can
be used in conjunction with other devices for face, jaw and head
protection, including improved protection against concussion or
similar injury.
[0011] It is still yet another goal of the invention to provide a
chinstrap that can be adjusted or adapted to a variety of helmet
designs and helmet--chinstrap attachment configurations.
[0012] It is also a goal of the invention to provide improved
strength in multiple components of the chinstrap and to provide
means that wear and weakness can be detected.
[0013] It is also a goal of the invention to allow adjustment by
each user to provide optimum fit for improved comfort and
protection.
[0014] It is another goal of the invention to provide protection
means that utilize replaceable components, thereby allowing energy
to be absorbed or dissipated in the destruction of the protective
device, which can then be easily replaced to provide continued
optimum protection.

[0033] The above general description and the following detailed
description are merely illustrative of the subject invention, and
additional modes, advantages, and particulars of this invention
will be readily suggested to those skilled in the art without
departing from the spirit and scope of the invention.
DETAILED DESCRIBTION OF INVENTION
[0034] The chin strap protection system subject of this invention
provides a flexible, adjustable attachment that securely fits a
helmet to the desired position upon the user's head, as well as
provides protection to the lower portion of the user's face,
particularly the chin, jaw and throat. The system may be adjusted
by each user to the individual's face and to multiple alterative
helmet attachment points for enhanced comfort or adaptation to
helmet use or other protective accessories.
[0035] One embodiment of the invention incorporates use of a fluid
gel bladder component such as described in U.S. Pat. No. 6,298,483.
This embodiment of this component is shown in FIG. 1, comprising a
plurality of fingers 273, 274, 276, 277, 278, and 279. The
invention provides improved fit and comfort by placement of a
flexible gel pad against the user's face. The gel pad 275 can
incorporate hydraulic properties that also provide additional
protection by dispersing energy created from a blow on the outer
portion of the chin protection system. The gel can also have the
additional benefit of providing the user relief from hot or cold
weather. The gel can be made of components that, when mixed current
to use, triggers a chemical reaction, which causes the gel
temperature to either increase or decrease. This temperature change
can provide temperature relief to the skin surface.
[0036] As part of this protection system of the present invention,
the fluid gel bladder or pad can be made to withstand one or
several impacts of a minimum force. However, upon a sufficiently
large impact, the bladder can rupture, providing additional
cushioning effect, and then be replaced with a new gel bladder.
[0037] This fluid gel bladder component can be used with or
incorporate an air filled bladder. It may be used in conjunction
with a separate fluid air bladder or be replaced by an air bladder.
The air bladder utilizes both the fluid and compressive properties
of a gas. This modification may be used to enhance fit and comfort;
as well as adjust the level of protection provided by the
invention. The air bladder can provide additional protection by
dispensing energy through the cushion of air. The air bladder may
be recharged by use of air valve. The individual user can also
adjust the level of air bladder firmness. The air bladder can be
filled with a static amount of air or it can be adjustable by the
user through a pumping device either using an athletic ball needle
and pump. These are use to inflate athletic balls and in some
football helmets model to adjust the helmet to the individual user.
The inflation device can also be of the nature used in athletic
shoes, which allow the user to regulate the amount of air in the
bladder by squeezing a small, built in pump. It may also be a small
hand squeezed pump that can be removeably inserted into the
bladder.
[0038] Not pictured is a cushion made of material such as
Sorbothane.TM. cushion. This material may also provide additional
or alternative protection by absorbing impact energy. Sorbothane
cushion is a proprietary product of Sorbothane Company.
[0039] FIG. 1A illustrates a side view of the fluid gel bladder 275
in conjunction with a foam compression pad 101 in FIG. 2. The foam
padding 101 provides protection by dispersing the energy of a blow
or impact. It is molded to conform to the shape of the hard cup,
also illustrated 200 in adjoining FIG. 3. The compression pad can
be constructed from any non-absorbent closed cell foam. The most
desirable of these foams is a micro cellular cross-linked
polyethylene with a relatively high EVA (ethylvinylacetate)
content. The EVA provides a fleshy feel. It is available in most
any color. It is closed celled and moldable. The compression pad
101 can be covered, in whole or in part, by moisture absorbing
material (not shown). This material can also contain anti-bacterial
agents. The moisture absorption can increase the user's comfort,
thereby facilitating the protective purpose of the chin guard cup
and the helmet.
[0040] The gel pad or bladder in FIG. 1 can be held in place with
an aggressive two-sided adhesive (not shown). The foam pad
illustrated in FIG. 2 has holes 102, 103 through it to allow or
airflow and serves as an exhaust outlet for the gel should the
bladder (275 of FIG. 1) rupture due to an extreme blow. This
provides additional protection, as energy is redirect out this
outlet. The opening also has the advantage allowing the distinctive
gel bladder color to be seen form the outside of the shell. The
foam padding provides enough protection to allow this chinstrap to
be fully functional with or without the gel pad in place. The foam
pad illustrated in FIG. 2 also comprises a foam lip 110 that
extends over the outer hard shell as discussed below. The gel
bladder can have both air and gel components.
[0041] FIG. 2A illustrates the interior of the foam pad 101,
including the foam lip 110. This foam pad may have a footprint 270
approximately matching the extended fingers 274-279 of the gel pad
illustrated in FIG. 1. The gel pad can thus be inserted or set into
the matching indentation. This is also illustrated in FIG. 8B. The
footprint can enhance ventilation for user comfort when not used in
conjunction with a fluid gel pad.
[0042] FIG. 7B illustrate the interior of the foam pad 101 within
the hard outer hard cup shell 200. Also shown is the relationship
of perforations which may be contained in both the hard cup 202 203
250 and the compression pad 103 104 150. It will be appreciated
that the perforations are contained in the compression pad 150 and
the hard cup 250 for attachment of flexible straps (not shown) for
attaching the system to the helmet. The hard cup may contain an
indentation 251 or other modification to facilitate use with the
flexible attaching straps.
[0043] Also illustrated in FIG. 7B is an optional flexible bumper
204A that can be used in conjunction with the hard cup. FIG. 7B
also more fully illustrates the relationship between the hard cup
lip 210 and the covering user protecting compression pad lip 110.
FIGS. 2 and 3 also provide illustration of the relationship.
[0044] FIG. 3 illustrates the hard outer hard cup shell 200 of the
chinstrap invention. This shell is made from a rigid material best
suited to disperse energy over a wide area. The edges 210 may be
rolled and smooth to insure comfort and provide protection from
abrasion. The outer hard cup shell may also contain reinforcing
ridges or surface contours (not shown). The rolled edges, ridges or
contours may also generate additional strength in the same was as
"I" beam configurations add strength to a steel beam. The
construction of the shell may be of a hard rigid material such as
hard plastic, polycarbonate, Titanium (Ti) or other lightweight
metal or metal alloy. Polycarbonate is injection molded. Ti is
compression molded. A Ti part could be electro statically coated in
any color or left uncoated.
[0045] The outer hard cup shell also may contain a co-molded shock
bumper 205 that further absorbs and reduces energy through the
addition of this shock absorbing material. This may be rubber,
Sorbothane or some material that has shock absorbing properties.
The attaching component of the bumper is shown 204 in FIG. 7A and
204A in FIG. 7B. FIG. 7C illustrates one embodiment for a hard cup
bumper 204. The bumper includes a series of "step like" flexible
sections 542A 542B 542C that can be inserted into an opening of the
hard cup. Each section has a narrow portion 561 562 and an
offsetting step portion 543A 543B.
[0046] FIGS. 3, 4 and 7A illustrate the outer hard cup shell 200
containing one or more holes or openings 202, 203 through which the
distinctive color of the gel bladder (not shown but item 275 in
FIG. 1 and FIG. 1A) can be seen. These holes also serve to provide
ventilation for improved user comfort. The holes may also provide
means for gel or other fluid to escape after rupture. Of course,
the escape of the gel through these holes to the exterior of the
outer hard cup shell will identify the need for replacement of the
protective gel pad.
[0047] The strap 300 illustrated in FIG. 4 holds the cup 200 firmly
in place on the user's chin. It may be desirable that any strap
material 300 be coated or otherwise be non-absorbent. The strap
consists of a woven fabric material that may allow limited or no
stretching, e.g., nylon or polyester. The strap is coated with a
flexible vinyl or urethane. The chinstrap subject of this invention
is also unique in that the woven fabric may be encased in a clear
vinyl or urethane. Such strapping is available from Bioplastic,
located in Ohio. This allows the user to note any excessive wear at
points of stress. The woven fabric may contain visible information
such as, but not limited to, a school, team or other organization
name. The strapping consists of a single strap on each side that
loops through a slot 250 on the chinstrap. Currently most chinstrap
manufacturers use a vinyl-coated strapping such as the strapping
manufactured by Plexon located in Peizer, S.C.
[0048] Also illustrated in FIGS. 3 and 4 is the bumper 205 that
spans across the center opening 203. It will be appreciated that
this opening 203 corresponds to the opening 103 of the compression
pad illustrated in FIG. 2. Considering FIGS. 1A, 2, 3 and 4
together, it will be further appreciated that a gel pad
(illustrated 275 in FIGS. 1 and 1A) incorporated into the combined
foam pad 101 and cup 200, may be visible from the exterior of the
cup through holes 203 and 103.) Of course, the openings 202 in the
cup 200 also align with openings 102 of the foam pad 101.
[0049] FIG. 8B illustrates the combined elements illustrated in
FIGS. 1, 2 and 3 from the side or prospective opposite of FIG. 4.
Shown are the gel pad 275, that may be sitting within the footprint
(270 of FIG. 2A) of the foam pad 101, the foam lip 110.
[0050] FIGS. 5A and 5B illustrate the two different points of
attachment currently available on a football helmets. They are the
high hookup as illustrated in FIG. 6A or the low hookup illustrated
in FIG. 6B. One end of the strap 300 fits to the rear most snap 601
on a helmet 650 and the other attaches to the high hook up post 603
or the low hook up post 602. FIGS. 5A and 5B each illustrate an
unoccupied male component post 602 and 603 respectively of the snap
assembly.
[0051] FIGS. 5A and 5B also illustrates a strap splitter 350
allowing the strap 300 to fit either a high or a low hookup that is
unique to this invention. The splitter also allows the user to
adjust the strapping to insure that the cup 200 can be adjusted in
such a manner that the angle of the cup is always as the most
desirable angle to the chin in order to provide the maximum comfort
and protection. No other chinstrap allows such precise adjustments.
No other chinstrap is designed to fit either a high or low hook up
equally well. Typically the splitter is adjusted up or away from
the cup for a high hook up and down toward the cup for a low hook
up. Other chinstraps may be forced to fit one or the other but the
user will sacrifice a proper or optimal fit that will result in
less comfort and safety.
[0052] FIGS. 6A through 6D further illustrate a general depiction
of a splitter component. The splitter 350 may be made of nylon,
plastic, rubber, acetal (Dupont Delvin.TM.) or Ti materials. The
splitter may incorporate two or more traverse elements 310 320
around which the flexible straps are placed (not shown). An angled
covering subcomponent 330 located at the narrowed end 353 of the
splitter may contain a logo or other element 305. The splitter also
contains a broader, curved subcomponent 351 containing a first
traverse element 310 with a corresponding annulus 315. The splitter
350 depicted in FIGS. 6A-through 6D illustrates a second traverse
element 320 offset L (322A and 322B) to the thickness 312 of the
first traverse element 310 to facilitate use with multiple straps.
To facilitate adjustment of the straps to obtain improve placement
of the chin guard, ridged "grippers" 307 are placed on opposite
sides of the broad segment of the splitter. A second annulus 325 is
provided after the offset traverse element 320. The straps
connecting to the hard cup pass uner the 330 and past the narrowed
end 353.
[0053] FIG. 5 also illustrates the cup reinforcing lip 210, the
bumper 205 spanning opening 203, and the openings 202.
[0054] FIGS. 9A, 9B and 9C illustrate snap attachments looped or
threaded onto each strap end. FIG. 9C show the construction and
design of the snaps 606 used in one embodiment of the invention.
The snap attachments 606 comprises two attachable components, one
601A attached to strap (not shown) and suitably sized to mate over
and with a counter part snap attachment 601B on the helmet 650.
These components are used to secure the chinstrap to the helmet.
The snap arrangement typically is a male 601 B-female 601A type
configuration or other configuration as known in the industry. They
may be made from metal or plastic or acetyl with or without a metal
ring inserted inside the circle area which mates with the snap
(male) post 601B shown on FIGS. 9A and 9B. FIG. 9A shows the snaps
secured to a football helmet 650 in the high hook up position. The
unused snap (male) post 601B for the low hookup alternative is also
shown. FIG. 9B shows the snaps secured to the helmet in the low
hook up position.
[0055] FIG. 7A shows another front perspective (similar to FIG. 4)
of the rigid cup. Illustrated is the bumper 205 crossing the center
opening 203, the slots or openings 250 for the strap (not shown)
and additional openings 202. FIG. 7B illustrates a cross sectional
view of the invention, including the rigid cup 200, the foam pad
101 and the gel pad 275. Also illustrated is the center hole 203 of
the rigid cup and bumper 205 aligned with the center hole 103 of
the foam pad. The relationship to the foam pad lip and the
reinforcing lip 210 of the cup 200 is also illustrated.
[0056] The bumper 205 illustrated in FIG. 7A may be shaped or
otherwise configured to containing information such as, but not
limited to, a school or team name or logo, the users name or
number, or similar information. It may also provide advertising or
promotional information.
[0057] FIG. 8 illustrates the embodiments and components of the
invention discussed in conjunction with FIGS. 1, 2, 2A, 2B, 3 and
4. The numbering sequence used for the identification of components
is continued from the other Figures and above text.
[0058] FIG. 9 illustrates an embodiment of the invention comprising
the helmet snaps 606, the connecting woven and coated strap 300,
the adjustable splitter 350, outer hard cup shell 200, flexible
bumper 205, center perforation 303 and additional holes 202.
[0059] While the narration and illustrations show the chin strap
subject of this invention used in conjunction with a football
helmet, it should be noted that many of the same claims can be made
for other helmets including hockey, lacrosse, military and
more.
[0060] Further modifications and alternative embodiments of this
