Patent abstract
A vehicle structural frame member incorporates an internal lightweight brace member spanning between the opposing flanges of the co-joined hat-shaped members forming the structural frame member. The internal brace is formed of thin material, such as steel, to help the frame member retain its geometric shape when placed under a load. The internal brace can be formed into a ladder-like configuration with longitudinally spaced members that span between the opposing flanges to keep the geometric shape from collapsing. A substantial improvement in load carrying capability before collapse is obtained with a small increment in additional weight in the structural frame member.
