Abstract: A bumper for a motor vehicle, with the bumper being equipped with an energy absorber provided along a rear surface thereof with at least one recess. The energy absorber is disposed forwardly of a girder subjected to bending, with the girder being attached to a vehicle. The recesses are arranged in such a manner that an impact force is transmitted to the body of the motor vehicle with as little moment as possible so as to prevent a tilting of the bumper and associated motor vehicle parts such as a fender of the vehicle. With a bumper girder subjected to bending being mounted forwardly of the energy absorber, at least portions of the recesses diagonally face the area of incidence of the impact force. If the impact is directly incident on the energy absorber, the recesses lie in an extension of a direction of the point of application of the impact forces.

Abstract: A web seam for sheet metal parts and a process for producing the same wherein the web seam is provided with a triple layer web projecting from a surface of the sheet metal parts, the layers are formed from a first flange of one sheet metal part and a second flange of the other sheet metal part. The first flange and a portion of the second flange immediately adjoining the other sheet metal part are separately connected by spot welds or by cementing in an intermediate step. The projecting edge of the second flange is then folded over in a U-shape and extends over the first flange. Additional weld spots or cement are applied to the web seam, which weld spots or cement simultaneously cover all three layers. A bight portion joining the first leg and a second leg of the U-shaped flange has a bending diameter which is larger than a single thickness of the sheet metal and, preferably, is twice the sheet metal thickness.
