This invention is related to sports equipment; specifically, embodiments of the description are related to sports helmets.
There are many helmets used for safety while riding, such as: bicycle, motorsport, and equestrian helmets that incorporate deforming non-rebounding materials because such materials have superior energy absorption characteristics versus non-deforming rebound materials. These riding helmets all share something in common, which is that the integrity of the capacity of the helmet to absorb impact deteriorates dramatically after one impact and it is recommended by the manufacturer that the entire helmet be replaced after each impact. In other words, if you fall off your bike and hit your head, the ability of the helmet to protect the user has been compromised for further use by that single impact.
Currently, no hard-projectile sports helmets, such as: baseball, softball, or cricket helmets incorporate the deforming non-rebounding material used in riding helmets. This is because hard-projectile sports helmets are designed to be used through multiple impacts without replacing the helmet or delaying the game. All hard-projectile sport helmets are designed for durability, and while this provides cost and convenience advantages, it doesn't provide the maximum single strike energy absorption user protection and safety offered by the deforming non-rebounding material used in riding helmets.
The design described below allows users of helmets designed for sports where the emphasis is protecting the user from hard projectiles to have the safety of the deforming non-rebounding crumple material of riding helmets and the durability of traditional sporting helmets by merging a removable and replaceable shell of non-rebounding crumple material over a traditional helmet shell into a single unified helmet design. Currently, there are no helmets that have two detachable shells incorporated into its form, whereby one shell houses a deformable non-rebounding impact absorption material. The two-shell design comprises an inner traditional helmet with a hardened shell, and a second outer shell that houses deforming non-rebounding crumple material. The second shell (outermost shell) is designed to flex and rebound upon impact allowing force dispersion from the flexible outer shell itself into the sandwiched non-rebounding crumple material between the inner and outer shell. This two-shell design, with a hardened inner shell and a flexible outer shell, creates a crumple zone, which is composed of the non-rebounding deformation material between the two. Once the exterior shell has received a single impact; for example, by a pitched baseball; you can simply remove it from the inner shell and replace it restoring the full energy absorbing protective ability of the helmet.
A complete helmet assembly comprising an inner helmet assembly and an exterior shell assembly is disclosed which would be ideal for baseball, softball, and cricket helmets. The inner helmet assembly is similar to a standard helmet. The exterior shell assembly comprises two or more layers; one of said layers (preferably the more exterior layer) being hard and elastic and one or more of said layers (preferably a more internal layer) being a plastically deformable layer comprising a crumple zone that would need to be replaced after the exterior shell assembly receives impact. The user gets the energy absorbing advantages of both a reusable interior helmet and the advantages of single impact safety materials commonly used in bicycle and motorcycle helmets.
