Abstract
A protective device, such as a boxing helmet, rib or muscle protector, athletic mat, hockey helmet, motorcycle helmet and similar devices, is formed such that the major shock absorption is accomplished by a series of bowed, preferably plastic, members which flex when the device is subjected to an impact, so as to absorb the shock and dissipate its transmission to the user. Because of the nature of these bowed members, when the shock has been dissipated, the member returns to its original position so as to be able to absorb further shocks.
