<p>A cover for an airbag unit includes first and second separate door members each having a polyvinyl chloride outer shell, a urethane foam pad and a yieldable thin metal back plate with a side flange connecting each of the first and second door members to an airbag housing to define a soft-feel horn hub within a steering wheel having a styling line thereacross; the two members are adhered to a rigid urethane foam member to prevent separation therebetween. The rigid urethane foam member fills between the door members and the airbag unit such that deployment of the airbag unit will immediately impact thereon to cause the thin metal back plates to hinge outwardly with respect to the housing to open the two separate door members for airbag deployment. <IMAGE></p> |
