ABSTRACT:
A rollformed tubular vehicle bumper beam is mounted on a vehicle. The bumper beam is fabricated of ultra-high strength steel and has a plan view sweep value of more than 10. The bumper beam has a cross-sectional configuration comprising an upper wall, a lower wall, an outer wall, and an inner wall. Inner portions of the upper and lower walls are angled, respectively, downwardly and upwardly. This configuration permits fabrication of the bumper beam by rollforming without stretching the outer wall to a point where it would be damaged. The position of the bumper beam on the vehicle is adjustable vertically, transversely, and longitudinally with respect to the vehicle.
