Abstract
A motor vehicle steering wheel and method, the steering wheel including a circular rim made from a hollow, seam-welded steel tube and a plurality of spokes made from solid steel rods. The seam-welded tube is indented in the center thereof perpendicular to the plane of the rim to form a plurality of integral troughs elongated in the circumferential direction of the rim and each flanked on opposite sides by a pair of integral resistance welding projections having inverted U-shape cross sections for structural rigidity. The spokes are arrayed across respective ones of the troughs in point contact with the corresponding ones of the resistance welding projections. The spokes are pressed against the resistance welding projections while electric current passes between the two to resistance weld the spokes to the hollow metal tube at the resistance welding projections.
