Abstract
Abstract A method and steering wheel assembly having a steering wheel comprising a preselected material continuously molded onto at least a driver's side thereof to conceal the air bag when the air bag is mounted to the steering wheel. The preselected material covers at least a driver's side of a rim section, a center section and a spoke section which joins the rim and center sections. The invention provides an integral construction which permits a steering wheel manufacturer to provide a steering wheel having a continuous molded construction on at least a driver's side thereof. This also enables steering wheels to be manufactured in a variety of shapes and sizes.
