Abstract

A retainer assembly (22) for supporting an air bag inflator (24), the retainer assembly comprising: a hollow body (40), through which the inflator (24) is inserted, having a first end (28) and a second end (32), the second end including a first member for securing a cooperating second end of the inflator (36), the first end cooperating with a corresponding first end of inflator to provide a friction fit between the two components which acts to reroute gas through the retainer vent notch (46). The retainer (22), along one side thereof includes a set of access openings (48a) and (48b) and along an opposite side thereof a set of mounting holes (50a) and (50b), a respective one of the access openings aligned to a corresponding mounting hole, a set of fasteners (52) mounted to the retainer (22) through corresponding mounting holes (50a) and (50b), the access openings (48a) and (48b) providing access to a portion of the fastener to permit the fastener (52) to be secured to the retainer (22) at the corresponding mounting holes (50a) and (50b).

Claims

1. A retainer assembly (22) for supporting an air bag inflator (24), the retainer assembly comprising:

a hollow body (40), through which the inflator (24) is inserted, having a first end (28) and a second end (32), the second end including first means for securing a cooperating second end of the inflator (36), the first end cooperating with a corresponding first end of the inflator to provide a seal which acts to reroute gas through a retainer vent notch (46);

the retainer (22), along one side thereof including a set of access openings (48a) and (48b) and along an opposite side thereof a set of mounting holes (50a) and (50b), a respective one of the access openings aligned to corresponding mounting holes, a set of fasteners (52) mounted to the retainer (22) through corresponding mounting holes (50a) and (50b), the access openings (48a) and (48b) providing access to a portion of the fastener to permit the fastener (52) to be secured to the retainer (22) at the corresponding mounting holes (50a) and (50b).

2. The device as defined in claim 1 wherein the opposite side of the hollow body (40), having the mounting holes, is flat.

3. The device as defined in claim 1 including an exit opening formed in the retainer as said vent notch (46), proximate the second end.

4. The device as defined in claim 3 wherein the exit opening or inflation gas notch is formed by removing a sector (46) of the retainer (22).

5. The device as defined in claim 4 wherein the exit opening (46) is aligned to an exit port (32) of the inflator.
