    • A bumper for vehicles, with a symmetrically backswept rail, is supported on a skeleton member of the vehicle body via shock absorbing arrangement. To simplify the construction by use of so called foam systems, and at the same time ensuring a high system efficiency, the shock absorbing arrangement is formed by an impact damper extending over the rail length and made of energy absorbing (EA) foam. Arranged in the midle of the bumper is a regenerable shock absorber which works on the positive displacement principle, passes through local clearances in an impact damper and in the rail and is supported on the skeleton member and on a trim shell engaging at a distance round the rail. An impact strip made of EA foam is inserted between the trim shell and the rail.
