ABSTRACT:
A motor vehicle bumper has a crossmember fixed to the body and an impact-confronting collision part. Non-regenerable deformation members are arranged between the collision part and the crossmember, at least in the region of support points, and the impact-confronting collision part is secured to the crossmember via fastening bolts passing through the deformation members. During a deformation of the non-regenerable deformation members, the collision part is displaceable in the longitudinal direction of the vehicle in order to increase the deformation capacity, while preserving the indicator effect of the support points. The collision part is designed as a trim part encasing, at least in the region of the support points, a core consisting of elastically deformable foam. With the exception of the region of the support points, the bumper has a gap on the energy-absorber side. Each fastening bolt is surrounded by a spacer sleeve supported, at one end, on the head underside if the sleeve and, at the other end, on the crossmember fixed to the body.
