ABSTRACT:
The bumper system of the present invention is of a modular design wherein two substantially identical, laterally extending members are secured at their laterally innermost ends to define an integrated bumper device and wherein each module includes an energy absorbing hollow core element formed of a relatively rigid, though deflectable, high strength plastic material mounted in front of and upon a relatively stiff transverse support beam member which is, in turn, adapted to be secured to a vehicle frame through a suitable rearwardly extending bracket structure and which energy absorbing element and support beam are encapsulated in an elastomeric outer skin layer.
