ABSTRACT:
An improved energy absorption device of the type incorporating a core member having layered arcuate bands each formed of a corrugated configuration with apices. Each corrugated layer within the core member is stacked in contact with each other having the adjoining arcuate bands overlaying in abutting relationship and joined to each other. The core member is mounted to a support member. A deformable outer body enclosure surrounds the support member and the plurality of the corrugated arcuate bands so that when a force strikes the shock absorption bumper, the apices of the layered bands permanently deform by concurrent flattening of the arcuate bands in engagement with each other. The plurality of corrugated bands thereby concurrently resist and absorb the striking force.
