Abstract:
A bumper to absorb energy of motion during a motor vehicle collision, comprising a bumper beam and an energy absorber with a plunger having symmetric protuberances, so that the cross section of protuberances changes along their lengths, an outer tube, and a cutter that cuts off protuberances throughout movement of a collision, where cutting force is controlled by the cross-sectional area of protuberances and provides constant deceleration with minimum force applied to a passenger cabin.
