Abstract
An impact damper as a connecting member between a bumper and a chassis of a motor vehicle for the purpose of damping the shock loading during a collision between this motor vehicle and an obstacle, predominantly through deformation work in a tube of the impact damper. The tube is connected to the chassis via a bracket and to the bumper via a bumper receptacle. The bumper receptacle, the bracket and the towing lug with the tube are connected to one another by a joining technique before they are connected to one another by a stamping operation. The advantage of the invention lies in low-cost production without compromises in terms of the functioning of the impact damper.
