Abstract
A vehicle bumper bar includes a swept B-shaped beam section and one-piece end pieces attached to opposing ends of the beam section for forming a compound angle along a front of the bumper bar. The end pieces are tubular and include circumferentially overlapping flanges that allow the shape of the end piece to be circumferentially adjusted to a best-fit condition on the ends of the beam section, and further include attachment tabs that longitudinally engage the ends of the beam section. The attachment tabs extend from the end piece longitudinally and circumferentially onto the beam section, in order to provide optimal impact and attachment strength of the end piece on the beam section. A method includes positioning the end piece on an end of the beam section, clamping the end piece onto the end including shaping the end piece circumferentially to a best-fit shape, and securing the end piece to the beam section by welding.
