Abstract
A vehicle bumper beam includes front, rear, top and bottom walls and a reinforcement wall that define upper and lower tubes. The front wall includes a vertical section, an angled section, and a bent section. 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. Also preferably, the front wall is at least about 3 mm and the remaining walls are less than about 2.0 mm thickness, or more preferably the exterior ones of the remaining walls are less than about 1.7 mm. In one embodiment, the upper and lower tubes are spaced apart.
