ABSTRACT:
A unitized bumper assembly for direct attachment to support structure within a vehicle comprising an elongated resilient blow molded hollow shell with continuous walls made from thermoplastic material to predetermined width and height and forming an air-tight cell. The assembly has laterally spaced bracket means encapsulated in said inner face during blow molding which accommodates fastener means for connection of said shell to a vehicle whereby a load of predetermined magnitude to said shell between said brackets is dissipated by the inward deflection of said shell as a deflecting beam.
