Abstract
An impact shock absorber is mounted between the bumper and body of a motor car and permits the bumper to move relative to the car body when the bumper hits an obstacle. The shock absorber damps the impact energy during this relative movement. It consists essentially of a cylinder wherein a piston is glidingly mounted and held under a yielding force in a rest position. The piston is weakened at its connection to the inner end of the piston rod that the piston will break off the rod under a selected maximum impact force.
