Title: Vehicle frame assembly having integral support surfaces

Abstract: A vehicular body and frame assembly includes a pair of side rails, wherein one or both of the side rails has an integral support surface formed therein to facilitate the mounting of various components on the vehicle frame assembly. Each of the side rails is formed from a closed channel structural member having a desired cross sectional shape. A portion of each side rail is further formed having a cross sectional shape that is substantially similar to, but rotationally offset from, the cross sectional shape of the remainder of the side rail. The transitions from the side rails to the rotationally offset portions and from the rotationally offset portions back to the side rails are preferably smooth and continuous. The rotationally offset portions may extend throughout any desired portion or portions of the side rails, and may further vary in the amount of rotational offset if desired. Thus, the rotationally offset portions of the side rails can be oriented in such a manner as to provide cradle-like support surfaces for a component to be mounted on the vehicle frame assembly, such as a portion of an engine or transmission.
