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.
