Abstract: A bumper for a motorcar having a shock absorbing member made of a foamed synthetic resin attached to a front surface of a backup beam connected to left and right stays of a car body. The resultant assembly of those members is covered at its front, upper and lower surfaces with a synthetic resin facing member which is nearly in the form of a channel in section.

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.
