Abstract
Abstract A helmet includes a plurality of cushion pads specially constructed and arranged within a shell to provide head protection against impact forces as well as ready means for custom sizing of the one shell to fit various head sizes and configurations. Each pad comprises a cover containing an improved cushion filling of compound layers of discrete material while the rear of each pad is provided with manually separable fastening means for ready attachment to and removal from the shell interior. One or more of the pads may be varied in thickness by the selective insertion/removal of shims within the cover.
