Shock absorption bumper for an automotive vehicle

Claim 1

A bumper for a heavy goods vehicle comprising: a support member; a core member comprising a plurality of arcuate bands mounted to said support member, each of said plurality of arcuate bands having a corrugated configuration, said corrugated configuration forming troughs and ridges with symmetrical offset apices, said apices in each band defining axis of orientation parallel therebetween, said arcuate bands being stacked in direct contact with each other with the apices of said corrugated configuration of adjacent arcuate bands overlaying each other in abutting relationship so as to form spaces between adjacent bands; means joining said abutting apices to each other, said plurality of arcuate bands thereby formed into a tier, said tier being concurrently deformable under compressive loading by flattening of said corrugated configuration of said plurality of arcuate bands; means for mounting at least one of said plurality of arcuate bands to said support member; and a deformable outer body enclosure means entirely surrounding said support member and said tier, said outer body enclosure means being in contact with said support member and at least one of said plurality of arcuate bands so that when a force strikes said enclosure means, said arcuate bands permanently deform by concurrent mutual flattening of the apices, thereby resisting the striking force and absorbing said force.
