Abstract: A resilient bumper assembly for a vehicle having an elongate horizontal beam mounted transversely to an end of the vehicle. Exterior flexible sheet cladding mounted on the beam defines an elongate internal chamber between its inner surface and the outer surface of the beam. An elongate resilient impact absorber is mounted to the beam and housed within the internal chamber, with top, bottom, inner and outer surfaces. Vertically extending cavities within the impact absorber, each opening to at least one of the top and bottom surfaces of the impact absorber provide resilient collapsing and rebound of the impact absorber on impact. The absorber may include variations in the size and shape of cavities, thickness of walls between cavities, and variations in the characteristics of material of which it is molded in order to modify the resilient characteristics of the absorber to suit different design needs.
