Abstract
Shock absorber for motor vehicles having an outside tube and at least one inside tube, the tube lying on the inside projecting out of the outside tube and the part of the inside tube lying within the outside tube having a larger outside diameter than the inside diameter of the outside tube interacting with it. The tube lying on the outside has two bores going through it perpendicular to its lengthwise axis, and at least one of the bores is placed in the area containing the inside tube, and the inside tube has, in the area of this bore in the outside tube, continuous lengthwise slots that overlap the borehole. Holes are present on the car body that overlap the crosswise bores and screws are provided that go through the holes on the car body and the crosswise bores. The shock absorber absorbs force through deformation of the outside tube by the inside tube as it is pushed by an impact on a free end of the inside tube which may carry a vehicle bumper, for example.
