Abstract

A vehicle bumper assembly including an elongated mounting beam adapted for being an integral part of the vehicle structure and an energy absorber for absorbing impact energy. The energy absorber is connected to the mounting beam and is supported thereby. The assembly is characterized by the mounting beam including two vertically spaced and interconnected hollow tubular portions. Each of the tubular portions has a closed crossed section and extends along the length of the mounting beam for providing structural rigidity and minimal deflection of the beam under impact loads. The mounting beam and tubular portions may be made from a single piece of sheet metal or the tubular portions can be stamped from separate pieces of sheet metal welded together to form the mounting beam.
