Abstract
A vehicle structural frame having a plurality of tubular elements is formed from first and second generally C-shaped elongated members. Each member has a first flange and a second flange separated by a web. The flanges of the first and second members overlap each other to form two pairs of overlapped flanges. Each pair of overlapped flanges of both the first and second pair of overlapped flanges are joined by at least two longitudinal welds. The longitudinal welds join each pair of flanges to form each element of the plurality of tubular elements of a vehicle structural frame. Lengthening the flange overlap and providing two or more longitudinal welds increases frame bending stiffness allowing reduced member thickness and weight.
