Abstract: A rail assembly which is especially advantageous for use in constructing the frame and underbody of a motor vehicle comprises an upper channel member, a lower channel member and an intermediate member or web in the form of a corrugated sheet secured between the channel members and whose margins abuttingly engage the peripheral walls of the channels. Each furrow and ridge preferably comprises a planar panel portion. Each planar panel portion is interconnected by a web panel portion which is preferably angled at an acute angle with respect to the transverse axis perpendicular to the longitudinal axis of the rail. Preferably, each planar panel portion has a trapezoidal shape to maximize resistance to bending moments along the longitudinal axis of the rail. The rail design can also be incorporated into other structural elements in a vehicle, i.e. in a pillar arch or a vehicle body, to provide additional rigidity to the vehicle structure.

Abstract: A spring for use in a vehicle suspension comprises at least one leaf having longitudinal ends tapering outwardly from one end of the spring to the other to form a substantially trapezoidal shaped leaf spring. The leaf is resiliently biased by a spring constant to a normally semi-elliptical shape which deflects into a substantially linear orientation when the vehicle supported upon a ground surface by the suspension. The linear orientation of the usually semi-elliptical spring maximizes resistance to lateral distortion in the direction normal to the longitudinal axis of the spring. Preferably, the spring comprises a single leaf having tapered longitudinal edges and an eye at each longitudinal end adapted to receive a mounting pin therethrough.
