<p>A retainer ring (10) having an air deflector (14), for use with an airbag mounting structure, includes a flange (16) in which an inflater opening (11) for receiving an inflater (40) is formed; and a wall (14), a base of which is connected to the flange (16), extending upward and outward from the inflater opening (11) at a predetermined angle to diffuse and deflect exploding gas upward. The wall (14), which realizes a simplified configuration for the retainer ring (10), may include convex portions projecting inwardly towards the inflater opening (11), being regularly spaced, and rib formations integrally formed on an inner side of the wall between the convex portions. The rib formations are evenly spaced, as a pair of rows covering the height of the inner side of the wall, and slope downward on either side of the convex portions. The airbag mounting structure clamps the inflater (40) and the airbag (20) between the retainer ring (10) and a baseplate (30), which is mounted to a support within an automobile. To determine a mounting position and orientation, a tabbed cut-out (12) is formed in the retainer ring, juxtaposed to a coupling hole (13) thereof, and is bent at a right angle to pass through an alignment notch (12) formed in a flange (41) of the inflater and a series of alignment holes (22,32) formed in the other components (20,30).</p> |
