Abstract
A closed channel structural member, such as a side rail or a cross member, for use in such a vehicle body and frame assembly that includes an internal reinforcing structure to increase the strength and rigidity thereof. The side rail can be generally rectangular in cross sectional shape, including first and second side rail sections having generally C-shaped cross sectional shapes. The reinforcing structure can be generally hat-shaped or W-shaped in cross sectional shape, including a central reinforcing portion extending between a pair of base portions. The central reinforcing portion can either be laterally spaced apart from or directly abut a central web portion of one of the side rail sections. The base portions can be generally L-shaped in cross sectional shape, including legs that terminate adjacent to the ends of the other of the side rail sections to facilitate the assembly process. A pair of such reinforcing structures can be disposed within the side rail and abut one another in end-to-end fashion. Alternatively, tabs extending from each of the reinforcing structures can is partially overlap one another to provide additional strength and rigidity.
