Resilient vehicle bumper indirectly secured to a rigid support
 A bumper formed by a rigid support of U-shaped cross section and a resilient guard covering it, with the guard having approximately horizontally aligned guide bars which rest against parallel legs of the rigid support and interact in a reinforcing manner with holding fixtures of the rigid support. For purposes of safe assembly and avoidance of overstressing the guard, additional horizontally-running cross bars are located at a vertical distance from the guide bars and include portions that protrude beyond the support. The protruding portions of the cross bars are connected to each other by means of a fastening link.
