ENERGY ABSORBER FOR REAR BUMPER OF VEHICLE

摘要

PURPOSE: The energy absorber for a rear bumper is provided to reduce the weight of a vehicle body and to enhance the working efficiency of manufacturing the rear bumper by replacing an existing impact beam with a foam-resin formed portion to allow the formed portion to be mounted to a vehicle body frame. CONSTITUTION: An energy absorber of a rear bumper comprises an absorbing portion(110) and a mounting portion(130). The absorbing portion(110) is fabricated of foam resin in the form corresponding to a facia. The absorbing portion(110) is rounded at the upper edge thereof. The absorbing portion(110) is formed with a plurality of shock dispersing grooves at the lower side thereof. Each of upper and lower surfaces of the absorbing portion(110) has a downward directed oblique surface. The mounting portion(130) has a thickness portion extending integrally from the absorbing portion(110) to a back panel, using foam resin. The mounting portion(130) is shaped to conform to the shape of the back panel. Each of upper and lower surfaces of the mounting portion(130) forms a continuous surface with the front portion(110). The mounting portion(130) has a pair of mounting shaft(170,170'). Each of the mounting shafts(170,170') has a cross-sectional shape to conform to a hollow portion(210) of each of a pair of longitudinal bars(200) which are abutted against the back panel. The mounting shafts(170,170) are directed toward the longitudinal bars(200).
