ABSTRACT:
A shock-absorbing bumper arrangement for a motor vehicle, comprising a cover made of an elastic material and a beam is constructed so as to eliminate the use of hydraulic damper struts by constructing the beam of fiberglass-reinforced plastic (at least in its transversely extending part) and fixing the beam to body frame elements in the manner of a 2-point loaded beam at two locations spaced relatively far apart outside of a middle longitudinal plane of the vehicle. The beam is constructed of a transverse part and approximately longitudinally directed support parts which secure the beam to body frame elements. In accordance with one embodiment, the transverse part and the supports of the beam are unitarily constructed as a single piece, while, in accordance with a second embodiment, the transverse part, which is formed of fiberglass-reinforced plastic, is formed as a part that is separate from the support parts, which support parts are formed of a light metal and plugged into hollow ends of the beam. Forwardly directed horn-like projections are provided on the transverse part, and obliquely directed horn-like projections are provided at a transition area between the transverse part and the support parts.
