INNER CUSHIONS FOR HELMETS |
摘要 |
It is based on a composite foam sandwiched between two foils. The composite foams of the present invention avoid the "bounce back on head" effect by converting a large fraction of the incoming kinetic energy in plastic deformation of the material. Two covering foils, either made by a metal (i.e. aluminium) or a combination of a metal and a polymer (i.e. mylar), protect the cushion material against environment and other eventual damaging agents. |
