Abstract
The bumper system of the present invention is of a modular design wherein two substantially identical, laterally extending members are secured at the laterally innermost ends to define an integrated bumper device and wherein each module is formed of three preformed and structurally self-supporting elements adapted to be nested together and adhesively secured to form an integrated module including an elastomeric outer shell open at its rear most face, an energy absorbing hollow core element formed of a relatively rigid, though deflectable, high strength plastic material adapted to nest within the outer shell in abutting relationship with the relatively stiff transverse support beam adapted to abut against the hollow core element and enclose the open rear face of the outer shell and which beam and hollow core element have coacting faces formed to resist relative impact-induced movement therebetween.
