A shock reducing helmet includes a helmet body made of an outer and inner shell, ear openings, and face shield or visor that connects flush to the helmet body.
The outer shell is formed from the strongest and lightest weight materials, such as polycarbonate, or other plastics, Kevlar, carbon fiber, or metal, to provide a high strength to weight ratio and minimize fracture.
The inner chamber includes shock absorbing structures made from materials such as a nickel-titanium shape-memory alloy, polycarbonate, other plastics, Kevlar, carbon fiber, or metal. Some variants have a viscous or gaseous layer around the springs to increase stability upon linear and rotational impact.
The face shield or visor is made of a clear polycarbonate that connects flush with the outer shell to eliminate visibility interference and rotational injuries caused by competitors pulling the metal bars commonly present in football helmets.
