Abstract
The bumper beam 11 of a vehicle has a hat profile and it is mounted in two tapered crash boxes 12, 13, which extend into the hat profile with their narrow ends. These narrow ends are fixed to the bottom of the hat profile so that the crash boxes will flatten out the hat profile when they are axially compressed. This arrangement is particularly advantageous for reducing the damages in low-velocity offset crashes that have an effect on only one of the crash boxes since it reduces the risk of damages on other parts than the crash box and the bumper beam.
