Abstract

A bumper system includes a bumper beam having a face and ends, and an energy absorber mounted on the face. The energy absorber has a foam piece engaging the face and an injection-molded end piece securely attached to each end of the foam piece and also engaging the face. By this arrangement, the energy absorber is a single unit that can be handled and attached to the bumper beam, and also can include different end pieces while still using the same foam piece. In one form, the energy absorber also includes a center injection-molded piece and, in another form, includes a long injection-molded piece having foam sections molded onto it.
