Abstract

A motor-vehicle bumper assembly has a transverse rigid and U-shaped rail having an inner wall closely juxtaposed in a normal motor-vehicle travel direction with a frame of a motor vehicle, an outer wall spaced farther from the frame than the inner wall, and a horizontal wall extending between the inner and outer walls. Two crush cans spaced transversely apart support the rail on the motor-vehicle frame. Each can has a first U-section element extending in the direction and having an inner end fixed to the frame and an outer end fixed to the inner rail wall and a second U-section element nested with and mostly vertically offset from the respective first element and having an inner end fixed to the frame and an outer end extending past the inner rail wall. An outer mounting plate is fixed to the second-element outer end and to the outer rail wall.
