Abstract

A bumper for vehicles, in particular automobiles, having a beam and dampers secured to the beam by means of retention devices in a manner so as to eliminate the use of auxiliary attachment devices, such as washers, cotter pins, etc., in order to prevent dislodgment of a bolt securing each retention device to the beam. In accordance with the preferred embodiments, each retention device and damper is provided with a bore. Within this bore a bolt is inserted that extends from an upper portion of the retention device, through the damper into a lower portion of the retention device. The bolt is retained in this bore either exclusively by bumper flanges overlying the opposite ends of the bore, or by the use of only one such flange and a blind bore having a check wall in the lower portion of the retention device.

Claims

1. A bumper for vehicles comprising, a beam and dampers which are secured to the beam by means of retention devices;

said beam having flanges and said retention devices having guide sections;

each retention device being secured at a vertical section of the beam and being connected to a respective damper by means of a bolt occupying a bore in the guide sections of the retention device, the guide sections having surfaces contacting inside surfaces of the flanges of the beam and the damper, the bolt having a height less than the distance between the flanges of the beam and being disposed solely between the flanges of the beam.

2. The bumper in accordance with claim 1, wherein the retention device has a hollow inner space, the insides of which being designed as a receiver for the damper.

3. The bumper in accordance with claim 2, wherein the guide sections and the receiver of the damper being formed by separate flanges of the retention device.

4. The bumper in accordance with claim 1 wherein the guide sections of the retention device and said damper being provided with a bore, said bolt being inserted into the bore so as to extend from an upper one of the guide sections through said damper into a lower one of the guide sections, and said bolt is retained in said bore at at least one end by an inner surface of one of the flanges of the beam.

5. The bumper in accordance with claim 4, wherein said bolt being retained in said bore at both ends by an inner surface of a respective flange of the beam.

6. The bumper in accordance with claim 4, wherein said bore being formed in a lower one of the guide sections of the retention device as a blind bore having a check wall for retaining said bolt with the bore, the inner surface of the beam retaining the bolt in the bore only at the upper end thereof.

7. The bumper in accordance with claim 1, wherein the vehicle is an automobile.

8. The bumper in accordance with claim 1, wherein the guide section is solid.
