- the various football leagues tried to implement new rules making it illegal for players to use their helmet as a weapon but the injuries still kept occurring.
- My solution is to make improvements to the equipment used so that, even if the new tackling rules were violated, the likelihood of serious injury is reduced by the addition of an exterior cushion.
- the cushioning effect of the exterior sport helmet pad does two things. First, it lessens the damage that can be done by a football helmet in much the same way a boxing glove lessens the impact of a punch as compared to a punch thrown with a bare fist. Second, when the wearer of an exterior sport helmet pad is tackled and strikes his head on the ground, the exterior sport helmet pad reduces the g-force on the head. Instead of the player's head smashing hard on the ground and stopping basically in half an inch, it now has another inch of stoppage by virtue of the thickness of the pad. Even if a player's head is violently smashed to the ground and, despite the exterior sport helmet pad, the player ended-up with a concussion, the severity of the concussion is dramatically reduced.
- this cushion is formed of a compressible natural or synthetic rubber, including but not limited to ETHAFOAM® polyethylene, NEOPRENE® polychloroprene, polyisoprene and like materials.
- the cushion can also be formed from styrene butadiene polymers, or combinations of the preceding materials. Closed cell foam has stable gas bubbles that compress and rapidly return to their normal size.
- ETHAFOAM® polyethylene is preferably a non-cross linked polyethylene closed cell foam used in the making of the exterior sport helmet pad.
- ETHAFOAM® products are available in a variety of strengths, making them suitable for protecting products ranging from just a few pounds up to hundreds of pounds of weight. This material is available in densities ranging from 2.0 pound density to 9 pound density. These foams are also available in anti-static and formulations.
- ETHAFOAM® military series (M-series) foams are prepared to meet the stringent military and blowing agent requirements, with less than 10 percent LEL. ETHAFOAM® M-series products also meet or exceed the requirements of CID A-A-59136 and PPP-C-1752.
- the exterior sport helmet pad dramatically reduces the ability of the football helmet to be a weapon against another player, it also reduces the impact on the head when the player is tackled and hits his head on the ground and; when two players end-up head to head in a tackling situation, there is two inches of cushioning by virtue of both helmets being covered with the one inch of ETHAFOAM®.
- NEOPRENE® polychloroprene is an all-purpose very tough synthetic rubber material that well maintains its strength and flexibility at a wide temperature range. It is available as high strength, medium and low strength material, or with inserted cloth such as fiberglass, or as a foamed material for shock absorption. These materials are manufactured in quantity in a range of thicknesses from which can be chosen the preferred thickness. Currently the preferred thicknesses are 0.5 inches (1 ⁇ 2 inches) and 0.75 inches (3 ⁇ 4 inches).
- High-strength NEOPRENE® polychloroprene is very tough, resists tearing and compresses to about 1500 psi; however, it is typically stiff which is valuable for flanges with a high bolt load, but not as useful for putting on and removing from a football helmet.
- NEOPRENE® polychloroprene is not quite as tough but still has high tensile strength and relatively low stretchability and is useful in this application.
- a preferred form is NEOPRENE® polychloroprene closed foam, which has great compressibility and firmness without being particularly stiff.
- closed foam products are suitable in this invention, including but not limited to “XPE” which is cross-linked polyethylene which has the property of not losing its compressibility over time.

If the person is wearing a seat-belt, the person also stops in about 18 inches. While this creates a tremendous g-force on the person's body, the person's body can usually withstand the force.
- If, however, a person is not wearing a seat-belt, the person keeps going forward at about 50 mph while the car is suddenly coming to a stop and the person hits the windshield or the dashboard of the car and the person stops in 2 to 3 inches, the person's body cannot stand that kind of g-force and the person will likely be killed.
- The number of concussions in football is on the increase as is the number of injuries incurred when players are struck by the hard plastic of a football helmet driven at them by another player. The various football leagues tried to implement new rules making it illegal for players to use their helmet as a weapon but injuries still kept occurring.

The exterior sport helmet pad is NEOPRENE® polychloroprene and non-cross linked polyethylene closed cell foam are light, tough and durable. The exterior sport helmet pad is used on a football helmet. The exterior sport helmet pad's holes are aligned with the holes on the helmet to provide ventilation to the user's head while the user is wearing the sports helmet and helmet pad. The exterior sport helmet pad is placed over the outer shell of the sports helmet.
- In yet another embodiment, an exterior football helmet pad has a formed base pad, the formed base pad being sized to fit a football helmet by internal contact pressure. The form base has a first plurality of holes, including a first pair of ear holes and the first holes providing ventilation to the formed base pad and the football helmet.

FIG. 2 illustrates a side perspective view of an exterior helmet pad made of NEOPRENE® polychloroprene. - The number of concussions in football is on the increase as is the number of injuries incurred when players are struck by the hard plastic of a football helmet driven at them by another player. The various football leagues tried to implement new rules making it illegal for players to use their helmet as a weapon but the injuries still kept occurring.
- The players today are bigger and faster than in previous years and with their greater weight and speed more injuries, including serious injuries, are occurring despite attempts to reduce injuries by making certain tackles against the rules.

FIG. 1 illustrates a side perspective view of an exteriorsport helmet pad 100. The exteriorsport helmet pad 100 includes a formedbase pad 110, to fitover asports helmet 120. The formedbase pad 110 has a first plurality ofholes 130 that are similar to a second plurality ofholes 140 on the underlying helmet. - The formed
base pad 110 accommodates asports helmet 120, including afootball helmet 122, a lacrosse helmet (not shown) or other protective helmet (not shown). The formedbase pad 110 is preferably coupled to thesports helmet 120 by internal contact pressure and can be removed as desired. The formedbase pad 110 may be made of non-cross linked polyethylene closed cell foam or ETHAFOAM®. The ETHAFOAM® unicellular plastic is extremely light while still being tough and durable. The ETHAFOAM® is sponge-like and cushions when pressure is applied to its surface, but unlike a sponge it will not absorb moisture. The formedbase pad 110 can be formed from a metal mold (not shown). Another example of a suitable synthetic rubber is NEOPRENE® polychloroprene, which is very resistant to the outdoor elements, has high tensile strength and flexibility. - The
sports helmet 120 provides some cushioning protection for a user's head but theouter shell 124 of thesports helmet 120 is made of a very hard plastic. As such, it can and is used as a weapon by football players who ram their helmet into the body of an opposing player. Thesports helmet 120 can be afootball helmet 122, a lacrosse helmet (not shown) or a protective helmet (not shown). - The first plurality of
holes 130 are disposed on the formedbase pad 110. Thefirst holes 130 provide ventilation to the formedbase pad 110 and thesports helmet 120. Thefirst holes 130 also include a first pair of ear holes 132 to allow a user to hear any nearby sounds or voices while wearing the exteriorsport helmet pad 100 and thesports helmet 120. The holes on the base pad preferably are near or overlie holes on the underlying sports helmet. -
More holes 140 are disposed on thesports helmet 120. The second set ofholes 140 provide ventilation to a user's head wearing thesports helmet 120. Thefirst holes 130 and the helmet holes 140 can be approximately the same size and shape. Thefirst holes 130 are but need not be aligned with the helmet holes 140 to provide ventilation to the user's head while the user is wearing thesports helmet 120 from the exterior of the exteriorsport helmet pad 100. The helmet holes 140 also include a second pair of helmet ear holes 142 that roughly align with the first pair of ear holes 132 in the base pad to enable a user to hear any nearby sounds or voices while wearing the exteriorsport helmet pad 100 and thesports helmet 120. - In use, the exterior
sport helmet pad 100 is placed over theouter shell 124 of the hard surface of afootball helmet 122 or a different protective helmet (not shown) used in sporting or recreational activities. The exteriorsport helmet pad 100 is coupled to thesports helmet 120 by internal contact pressure and can be removed as desired. There is a snug fit so that thepad 100 does not easily come loose upon jarring. -
FIG. 2 shows another version of thesport helmet pad 110 over thesame helmet 120. In this version, thesport helmet pad 110 is a NEOPRENE® polychloroprene mockup. This sport helmet pat more closely follows the contours of the underlying helmet. Although not shown, it can be easily equipped with the same holes shown inFIG. 1 to enable air circulation and better hearing via the sport helmet pad'sear hole 132. - To illustrate the improvements available with our helmet protector we test it in comparison to helmets alone. Before we sell any helmet protector, it is tested according to the protocols of the National Operating Committee on Standards for Athletic Equipment (NOCSAE). The most recent protocol for testing of helmets is the “Standard Test Method and Equipment Used in Evaluating the Performance Characteristics of Protective Headgear/Equipment” NOCSAE DOC (ND) 001-11m13. This discloses an apparatus to be used to obtain comparable data headgear drop testing. The apparatus consists of a frame and a helmet holder on a sliding vertical rail on one side of the frame. Basically a helmet (with the inventive protector) is affixed to the helmet holder. Initially helmet protectors made of NEOPRENE® polychloroprene with thicknesses of, for example, 0.25 inch, 0.5 inch, 0.75 inch and 1 inch are tested for impact reduction. Initially only NEOPRENE® polychloroprene strips are affixed individually in a “mohawk” location from the helmet front, crown and back of head. Head injury criteria (HIC) are calculated for each location and each thickness. HIC is calculated in a differential equation and preferably in less than 1000 units.
- The helmet holder is released to fall at least six feet. Various impact surfaces are provided for the helmet apparatus to fall onto, such as a 3″ calibration pad with specifications including molded polyurethane thermoplastic elastomer, a ½″ test MEP pad also of polyurethane or ⅛″ faceguard pad calibration also of polyurethane. Part of the system is a triaxial accelerometer that measures the impact vibrations in three orthogonal axes and is mounted inside the helmet holder that supports the helmet and protector. Data from the accelerometer are processed with standard Severity Index computation software. In addition, there is an electronic speed monitor to measure the last three inches of movement just above the collision. The test is run at standard room temperature. The tested parts (helmet and protector) are first conditioned to that temperature. Another test is run at 115° which is summer-field temperature in Arizona.
- This test is also called a linear impactor test because the test object falls in a straight line to impact. To assure accurate comparisons, the helmet, helmet holder and helmet protector are required to have an adjusted mass of 13.3 kg (±3%). Impact velocities are in the range of 6-12 meters per second. For other, non-football headgear, there are other standards to be applied.
- In the helmet impact test, usually the only result is pass or fail. For the helmet protector to pass, it must be able to withstand the impact at an acceptable severity index (SI). SI is a function of the acceleration at the last 1.5 inch of the six-foot drop taken to the power of 2.5 and multiplied by the short duration of the acceleration pulse. If the velocity at impact is too great, the test result is considered inconclusive and the test is re-run.
- With the inventive helmet protector, control tests of helmet impact without the inventive protector are also obtained to assess the improvement (decrease) in impact accelerometer data.
- While the invention has been described in conjunction with specific embodiments thereof, it is evident that many alterations, modifications, and variations will be apparent to those skilled in the art in light of the foregoing description. Accordingly, it is intended to embrace all such alterations, modifications, and variations in the appended claims.
