Helmet |
摘要 |
A helmet which includes a substantially rigid shell having a shell thickness defined by a substantially continuous exterior surface spaced apart from a substantially continuous interior surface. A one-piece first shock attenuating member is positioned adjacent to and in substantially in contact with portions of the interior surface of the shell. The first shock attenuating member has a first thickness and a first compression deflection. A plurality of discrete second shock attenuating members are positioned adjacent to portions of the first shock attenuating member and adjacent to and in substantially in contact with portions of the interior surface of the shell. Each second shock attenuating member has a second thickness and a second density, with the second thickness being greater than the first thickness and the second compression deflection being less than the first compression deflection.
