A steering wheel and air bag module assembly includes a steering wheel having a hub portion and a rim portion and a plurality of spoke portions connecting the hub portion to the rim portion. An air bag module is mounted to the hub portion and includes an air bag cover having a generally planar top surface. The top surface of the cover includes first, second, and third weakened portions defining a single Y-shaped tear pattern substantially covering the top surface of the cover. The air bag cover preferably has a generally planar top surface and generally vertical side portions extending generally downward from the top surface. The air bag cover includes a plurality of primary flap portions located substantially on the top surface and a plurality of secondary flap portions located substantially on the side portions. Advantageously, the primary and secondary flap portions and the Y-shaped tear pattern cooperatively provide an enlarged opening for air bag deployment. |
