Abstract
A motor vehicle includes a frame with energy-absorbing zones at outboard corners of the vehicle and a bumper beam mounted to the energy-absorbing zones to transfer force to at least one of the energy-absorbing zones during a collision. The bumper beam includes a center section extending generally laterally across the vehicle between the energy-absorbing zones, and left and right load transfer sections attached to outboard ends of the center section. Each load transfer section extends outboard and rearward such that the free end of each load transfer section is disposed outboard of the frame adjacent a rear end of its respective energy-absorbing zone. In a small-overlap collision, the load transfer section on the side of the impact bends rearward as the energy-absorbing zone deforms, and the free end of the load transfer section contacts the frame to transfer crash loads to the frame.
