ABSTRACT:
An improved strengthening or reinforcing member, and in particular an automotive vehicle door reinforcing beam, constructed from ultra high strength steel is disclosed. The door reinforcing beam has a substantially trapezoidal shaped cross-sectional geometry and optionally can include an additional reinforcement extending over a central portion of the beam. In an alternative embodiment, a rounded outboard flange portion can be substituted for a generally flat outboard flange portion. The door reinforcing beam exhibits a substantial improvement in load carrying capability for a given mass, as compared to door reinforcing beams having other cross-sectional geometries, such as hat-shaped cross-sectional geometries.
