Abstract
A bumper beam is formed from a tailor welded blank with thinner gage sheet metal laser welded to thicker gage sheet metal at opposing sides thereof. The tailor welded blank is then formed into a bumper beam having a uniform B-shaped cross-sectional configuration from one terminal end to the other. Each fore-and-aft extending wall of each cell of the B-shaped cross-sectional configuration is formed with first and second hinges at a bend line between substantially horizontal portions of the wall and an intermediate transitional portion such that the horizontal portions are at different vertically spaced positions. Upon receipt of an impact, the first hinges bend into the corresponding cell while the second hinges bend outwardly. The second hinges on the corresponding inner walls of the two cells contacting upon deep collapse to enhance energy absorption.
