[0038] The figures depict various embodiments of the described
methods and kit and are for purposes of illustration only. One
skilled in the art will readily recognize from the following
discussion that alternative embodiments of the methods and kits
illustrated herein may be employed without departing from the
principles of the methods and kits described herein.
DETAILED DESCRIPTION OF THE EMBODIMENT
[0039] The football helmet 1 disclosed herein is designed to better
protect the wearer from a head injury. More specifically, the
football helmet 1 is designed to reduce the risk of head and brain
injuries during the playing of the game. The embodiments taught can
be used for other helmets, including safety (construction)
helmets.
[0040] The typical football helmet 1 is made of a hard plastic.
More specifically, the football helmet is a hard shell 2 with thick
padding 3 on the inside and underneath the hard shell 2, a face
mask 4 made of one or more plastic-coated metal bars, and a
chinstrap 5 The plastic shell 2 is normally made out of
polycarbonate and can have a duro rating greater than about
100.
[0041] In one embodiment of the present disclosure, a plurality of
flexible energy divergent baffles (FEDBs) 6 are attached to the
outer surface 21 of the shell 2 of the helmet 1. The energy
divergent baffles 6 each comprise a base 7, a foot or support 9,
and an off center flat top 10 positioned and integral with said
foot or support 9. In one embodiment, a rectangular or square base
7 is positioned on top of an upturned pentagonal foot 9 which is
positioned on top of a flat topped pyramidal platform 8 positioned
on top and integral with the square base 7, with the off center
flat top 10 extending beyond one of the perimeter walls 11, 12, 13,
14 of the base. In another embodiment, the base 7 is not square or
rectangular, but any shape that gives the FEDB 6 enough balance.
Similarly, the flat top can be of any shape as long as it is
flat.
[0042] The height of the FEDB 6 can range from about a 1/4'' high
to about 1'' high. These ranges are not limited and the FEDB 6 can
be larger or smaller than indicated. To give some perspective, the
1'' high FED 6 has a base measuring about 1'' by about 1'' and the
flat top is about 7/8'' long and about 1/2'' wide. It should be
noted that the base of the FEDB 6 can range up to about 2'' or
more, if so desired, and the flat top can be proportionately larger
as well. These numbers may also vary. The FEDB 6 have a duro value
in one embodiment of no greater than about 35 to about 40. The duro
can be as lower or lower than about 30. In yet another embodiment,
the duro can be between about 40 to about 50. In one embodiment,
the FEDB 6 are made out of a flexible rubber such that they can
angularly bend when an item strikes them. In another embodiment,
the FEDB 6 is made out of plastic or silicone or any other material
that allows for the traits described therein. It should also be
noted that the material used should have memory.
[0043] In another embodiment, the FEDB can be in the general shape
of a "Z" 20. The base 29 of the "Z" 20 is attached to the outer
surface 21 of the shell 2 of the helmet 1. A thickened diagonal
section 22 supports a flat top 23. In yet another embodiment, the
FEDB can be in the shape of a staple 24. The staple shaped FEDB 24
has a base 25, a vertical support 26, and a flat top 27. For
clarity purposes, the proximal end of the of the vertical support
26 is positioned at one end of the base, and the distal end of the
vertical support 26 is attached to the flat top 27. The parts of
the FEDB are integrally attached, and in one embodiment are molded
in one piece.
[0044] Fundamentally, in another embodiment, the FEDB can be of any
shape, as long as the flat top is off center from a vertical
support 26.
[0045] The FEDB 6 is secured to the outside of the football shell
2. Any method can be used to secure the FEDB 6 to the outside of
the football shell 2, including the use of rubber cement, rubber
paint, and mixtures thereof, as well as other types of glues. There
may also be other means of attachment known in the art, including
small screws. In one embodiment, the FEDB 6 cover the entire outer
surface of the shell 2. When the FEDB are about one inch tall, it
takes about 70 FEDBs to cover the entire outer surface of the shell
2.
[0046] It should be noted that the FEDB 6 can be solid, or it can
be hollow. A hollow FEDB 6 will lighten the weight of the
helmet.
[0047] On the top of the off-center/offset flat top 10 of each of
the FEDB 6 is rigid flat wafer 16. In one embodiment, the wafer 16
is made out of carbonate, of which football helmets are usually
made In other embodiments, the wafer 16 is made out of aluminum, a
steel alloy, any metals or metal alloys stronger or lighter than
steel, and any plastics stronger and lighter than steel. The wafer
can also be made out of Kevlar. Depending on the material used, the
width of the wafer 16 can range from about 1/16'' to about 1/4''.
In one embodiment, the wafer has the same outer dimensions as the
perimeter of the flat top 10. In another embodiment, the wafer 16
extends beyond the perimeter of the flat top 10. The amount of
overlap of the wafer 16 on the flat top 10 may vary.
[0048] On top of the wafer 16 is attached a bumper 17. In one
embodiment, the wafer 16 is first attached to the bumper 17 before
being attached to the flat top 10 of the FEDB 6. In another
embodiment, the wafer is first attached to the to the flat top 10
before the bumper 17 is attached. In yet another embodiment,
everything is assembled before the FEDB 6 is attached to the
shell.
[0049] The bumper 17 has a duro hardness ranging from about 70 to
about 100 duro. The bumper 17 is in the shape of a semicircle or
more correctly, is in the shape of half of a hollow ball, and is
made out of either rubber or plastic. While the phrase "half a
hollow ball" is used, the shape is somewhat more or less than half
a hollow ball, such that there can be a ball that was cut on about
the 30% mark to about the 60% mark. The outside width of the bumper
can range in size from 1'' to about 2'' with some sizes smaller or
larger. In one embodiment, the outside width of the bumper is about
1.5 inches. In another embodiment, the outside width of the bumper
is two inches. Where the outside width of the of the bumper is at
least 1'' to about 2'', the width 28 of the rubber or plastic is
about 1/4''. The bumper 17 is attached to the wafer 16 by any
effective means known in the art, including rubber glue or any
other effective glue. In one embodiment, the bumper 17 is larger
than the wafer 16, and yet in another embodiment, the bumper 17 is
smaller than the wafer 16. Given that the bumper 17 is round, some
parts of the bumper may extend beyond the wafer 16. In another
embodiment, the shape and width of the base 36 is about equivalent
to the width and shape of the wafer 161t should also be noted that
the duro hardness of the bumper 17 may fall outside of the range
given, and may be softer or harder than indicated.
[0050] The bumpers 17, and the FEDBs 6 can be made out of rubber,
plastic, or other materials that have elasticity. The wafer 16 can
be made out of rubber, plastic, metal or other materials.
[0051] In yet another embodiment, the bumper 17 resides directly on
top of the FED 6, without the need of a wafer 16 interface.
[0052] In football, when a player is hit in the head, the impact
can be in excess of 150g forces. When the wearer of the present
helmet is hit in the head, instead of the energy being directly
transmitted to the player's head, thereby risking a concussion, the
bumpers 17 absorb and transfer the energy angularly away from the
point of impact. The FEDBs 6 further absorb and transfer the energy
angularly away from the point of impact. This lessens the risk of
concussion as the inertia energy is dispersed and distributed away
from the point of impact. Much of the energy is spent by the
movement of the bumper and the FEDB 6, while much of the impact
energy is distributed over the entire helmet.
[0053] Other embodiments can further lessen the effects of an
impact. In embodiment, the shell 2 of the football helmet 1 is made
of a material giving the shell a hardness rating less than about
100. In another embodiment, this shell 2 could be soft enough so as
to indent upon impact. In one embodiment, this soft shell 2 is made
of a soft plastic or a rubber having a duro at or under about 80
duros, and in one embodiment in about the 70 to about 80 duro
range. In yet another embodiment, the duro range of the shell 2 can
be in the about 30 to about 80 range, and in yet another embodiment
the shell 2 has a range of from about 30 to about 50. In yet n
another embodiment, only selected parts of the shell 2 have a
selected duro in the range of about 30-50, in order to reduce
impact-force transfer to the athlete's head. In another embodiment,
flex is engineered into the helmet's shell, facemask, and
attachment system.
[0054] In one of the embodiments, the largest section of helmet
padding is stiff polypropylene foam that nearly covers the entire
internal surface of the helmet. Its main role is to absorb impacts
and provide general protection. In another embodiment, the helmet
padding is a gel pad. In another embodiment, the helmet pad is is
water filled pad. This further allows for energy absorption from an
impact. In another embodiment EVA foam, a closed cell foam made
from ethylene Vinyl Acetate and blended co-polymers is used for the
inner pad.
[0055] In yet another embodiment, the seat of the chin strap, or
the part where the chin fits, has a gel cushion insert.
[0056] In yet another embodiment, there is a soft plastic outer
layer 30 covering the semi-circular bumpers 17. This soft plastic
outer layer 30, having a dur value of about 30 to about 50, will
provide additional protection both for the wearer of the helmet and
for any opposing player. In yet another embodiment, the soft
plastic outer covering has the same appearance as the shell 2, and
is unrippled on the outside surface 33 of the shell. There are a
number of ways known in the art to attach the outer covering. In
one embodiment, FIG. 12 shows one embodiment in which the plastic
cover 30, only partially covering the bumpers 17, have hooks 40
which attach to the helmet between the hard shell 2 and the thick
padding 3. In another embodiment, a hook and loop arrangement is
used. In other embodiments, other means of attachment, including
loops, can be used.
Testing
[0057] Several different impact sites on the helmet proposed by
this disclosure and compared to football helmets currently being
sold in the market place. The tests were performed by corner
Chesapeake Testing, a NTS company, which is itself is an accredited
independent helmet testing company. The actual tests performed
correspond to the standards and tests agreed upon by the NFLPA (The
NFL Players Association).
[0058] Three football helmets were tested, with two of the helmets
being those taught in the disclosure. One of the proposed helmets
tested has a bumper having a diameter of 1.5 inches, and the other
proposed helmets has a diameter of 2'' The other helmet is a
commonly sold helmet.
[0059] There are four terms used in the charts.
[0060] The Severity Index (SI) is a threshold value for a general
category of head injuries based on scientific research and
published data. SI is a method for measuring a helmet's ability to
reduce impact forces to the head, integrating acceleration over
time. SI provides an accurate way to assess head injury risk that
can be replicated across laboratories and under different impact
scenarios. The NOCSAE standards are performance based and are
design neutral so that manufacturers are not restricted in design
or engineering, allowing innovation in design.
[0061] Linear Acceleration is the acceleration of the head in the
direction of the impact. This is recorded in G's which is an
acceleration value related to free-fall acceleration.
[0062] Average Acceleration is the maximum linear acceleration
experienced at the center of gravity (center) of the head.
[0063] HIC 15 is a unit-less value that is closely related to SI,
capturing the most aggressive 15-milliseconds of the impact event.
The Acceleration vs. SI vs. HIC graph is shown in FIGS. 21A-21C.
The ambient conditioned impacts testing results are found in FIG.
22, the Hot Conditioned Impact results are found in FIG. 23. FIGS.
24, 25, and 26 show the Linear Acceleration test results, the HIC15
test results, and the Severity Index test results. The codes in the
Impact Site column correspond to the impact on the helmets shown in
FIGS. 13 through 20. The Baker helmets correspond to the helmets in
the disclosure and the tests are using the 1.5 and 2.0 inch bumpers
for the Baker helmets.
[0064] As the charts show, the Baker helmets cushion is a great
improvement over the standard football helmet. blows from those one
could expect in a football game. Such an improvement will greatly
reduce head injuries when playing football.
[0065] It should be noted that the embodiments described herein can
be used in combination with each other or with other embodiments.
Additionally, the safety features described herein may be used with
other helmets other than a football helmet. The safety features
could be used in construction helmets, for example.
[0066] While various embodiments of the present disclosure have
been described above, it should be understood that they have been
presented by way of example only, and not limitation. It will be
apparent to persons skilled in the relevant art that various
changes in form and detail can be made therein without departing
from the spirit and scope of the disclosure. Thus, the breadth and
scope of the present disclosure should not be limited by any of the
above-described exemplary embodiments, but should be defined only
in accordance with the following claims and their equivalents.
