Abstract: A shock absorber for a motor vehicle, having a bumper, a bumper shield and a cross-member interconnecting two side rails of the vehicle, comprising only one layer comprising a single sheet having an undulating section defining undulating shapes each having a concavity, wherein the shock absorber is interposed between the cross-member and the bumper shield, the concavity having an axis which is substantially parallel to a direction of impact, and the shock absorber is to primarily absorb energy from an impact.

Abstract: A device allows precise positioning of a second body part relative to a first body part. The first part includes a first pair of reference surfaces, a second pair of reference surfaces not parallel to the surfaces of the first pair, and an abutting surface. The second part includes a first pair of bearing surfaces, a second pair of bearing surfaces, each pair of bearing surfaces being arranged to enable each of the surfaces to come into surface contact with a corresponding reference surface and slide along the bearing surface upon installation of the second part on the first part, and an abutting surface encountering the abutting surface of the first part when the second part is installed on the first part.
