Claim Text:
1. A bumper reinforcement beam comprising: a beam having a length with a longitudinal curvature between ends of the beam, the beam comprising a single sheet of metal that is formed to include (i) a front wall that extends the length of the beam with a substantially constant height and (ii) top and bottom walls that extend rearward from respective top and bottom portions of the front wall along the length of the beam; wherein, at a center longitudinal section of the beam, the top and bottom walls extend rearward a greater distance than at the ends of the beam; wherein end longitudinal sections of the beam, on opposing sides of the center longitudinal section, each include a mounting portion configured to mount the beam to a vehicle frame; wherein, at the end longitudinal sections of the beam, rear portions of the top and bottom walls of the beam each include an edge of the sheet of metal that forms the beam; wherein, at the end longitudinal sections of the beam, the top and bottom walls each taper in depth, as defined by the edge of the sheet of metal, away from the center longitudinal section of the beam toward the ends of the beam; and wherein a first cross sectional shape of the beam taken at the end longitudinal section of the beam has a first bending moment and a second cross sectional shape taken at the center longitudinal section of the beam has a second bending moment that is greater than the first bending moment.
