Abstract
A method for forming a bumper beam includes providing an elongated piece of sheet metal having opposing end portions and an intermediate portion, bending the end portions with respect to the intermediate portion until the end portions are substantially perpendicular to the intermediate portion, bending a central section of the intermediate portion to form a protruding bulge in the intermediate portion after the bending the end portions, and bending side sections of the intermediate portion to move ends of the end portions adjacent to one another and adjacent to the protruding bulge after the bending the central section to from the bumper beam. The end portions form front walls of the bumper beam, the protruding bulge forms inner side walls and a web portion of the bumper beam, and the side sections form outer side walls and rear walls of the bumper beam.
