Abstract

A vehicle bumper beam includes front, rear, top and bottom walls and parallel reinforcement walls that define upper and lower tubes. The front wall includes a vertical section, an angled section, and a bent section on the upper tube. The reinforcement wall supports the angled section below the bent section to provide predictable and desired energy absorption. The angled section preferably includes an angled portion defining a first vertical dimension in the first tube and the vertical section defining a second vertical dimension, with a ratio of the first and second being about 1:3. In one embodiment, the upper and lower tubes are spaced apart.
