<p>An elongated body member (12) with a cavity (20) extending along at least a portion of a length of the body member, a beam member (14) positioned in the cavity in close fitting engagement, and an attachment device (16) for attaching the bumper system to a preselected structure (18). The body member cavity has a predetermined cavity cross-sectional shape and the beam member has a corresponding cross-sectional shape. The body member is constructed in one piece of a resilient, moldable material. The corresponding cross-sectional shapes of the body member cavity and the beam member are adapted to maximize torsional force transfer between the body member and the beam member. The beam member is configured to meet strength requirement with minimal mass. Each of the body member and the beam member may also include a void (34) that is filled with a foam material (35).</p> |
