Abstract
A steering-wheel skeleton has a hub, spokes, and a rim made in one piece out of a single sheet-metal blank and provided with its final shape by separation and bending without machining. The hub is provided with a cone facing the vehicle. The spokes, which extend up and out, are provided with unthreaded bores, cutouts, or threaded bore for attaching an airbag module. A nut can, if necessary, be forced into one cutout. The hub can be reinforced by using two layers of the material.
