An impact softening device or bumper for use on automotive vehicles consisting of resilient wheels rotatably mounted with adjustable braking means in horizontal position on vertical axles which are rigidly attached to extensions of the vehicle frame at the front and/or rear corners thereof. The resilient wheels are substantially in alignment with the front and rear wheels of the vehicle. The resilient surfaces of the horizontal wheels extend longitudinally and laterally several inches beyond the most protruding part of the vehicle body to give substantial protection when an obstacle is encountered.
