ABSTRACT:
An energy absorbing steering wheel for a motor vehicle includes a rim and a hub connected by a plurality of radial spokes, the combination of which forms a cage for influencing the path of expansion of an air bag, mounted in the steering wheel. The rim and spokes having integrated therein spring means which permit a change in orientation of the cage in response to pressure applied to the rim. Rupturable means are integrated into selected spokes which permit these spokes to break in response to a second pressure applied to the rim. This provides a steering wheel which will absorb energy applied to the rim and also change the path of expansion of an inflating air bag in response to the same applied energy.
