TITLE: WIRE SUSPENSION ARM INVENTORS: Louis J. Aure Harold L. Beck Robert A. Wuebker ABSTRACT OF THE DISCLOSURE A suspension arm is formed from a single wire having a coined U-shaped portion, a pair of wire portions extending divergently from the legs of the U-shaped portion and a coined annulus on the end of each wire portion. The axis of at least one of the wire portions is oblique to the plane of the coined U-shaped portion. The axis of the coined annuli are colinear and the plane of each coined annuli is at an angle to the plane of the coined U-shaped portion. A method of fabricating the wire suspension arm using cold working begins with upsetting the ends of the wire and proceeds with bending the wire into a U-shape, bending the wire to form divergent portions, at least one wire portion being oblique to the plane of the U, and bending the ends to be parallel to each other. The ends are coined and the bight of the U is coined.
