ABSTRACT:
A bumper arrangement for an automotive vehicle is disclosed which includes a bending-resistant bumper support resting on parts affixed to the vehicle, an undulating leaf spring extending over the length of the bumper arranged in front of this bumper support, and a cover which can be locked to the bumper support and which serves to hide the leaf spring from view. The leaf spring is fashioned integrally with the bumper support, and is preferably made of a reinforced synthetic resin. The wavy windings of the leaf spring are aligned in the support zone extending transversely with respect to the automotive vehicle, in the longitudinal vehicle direction, and, in the laterally wrapped-around end zones of the support, approximately in the transverse vehicle direction. Energy absorbing elements and impact buffers are interposed between the undulations of the leaf spring and between the bearing support and the adjacent section of the leaf spring.
