Abstract
A bumper structure includes an elongated rollformed tubular vehicle bumper beam. The bumper beam is fabricated of ultra-high strength steel and has a plan view sweep value of more than 10. A relatively thick layer of energy absorbing foam material covered by a facia overlies the bumper beam. The foam material is thickest at the center portion and decreases in thickness towards the longitudinal ends of the bumper beam.
