Abstract

An air bag cushion retention clip that, when used in conjunction with a two-part canister, distributes the deployment forces over the length of the clip. Further, the retention clip reduces the possibility that the sharp edges on the canister will cut through the air bag cushion during deployment thereof.

Claims

1. A device for securing an air bag cushion to a module housing comprising:

a canister having a substantially planar first section and a second section, said first section having a top edge, a bottom edge, a first surface and a second surface and a plurality of first apertures formed therein, said second section having a top edge and a substantially planar section adjacent said top edge, and a plurality of second apertures therein;

a diffuser comprising an attachment means and a plurality of third apertures formed therein; and

an air bag retention clip having a substantially planar section and an inwardly curved base section, said air bag retention clip having a plurality of fourth apertures formed therein;

said air bag cushion comprising a body that terminates at a gas inlet opening for said air bag cushion and a plurality of fifth apertures formed in said air bag cushion adjacent said gas inlet opening;

wherein said retention clip is attached to said air bag cushion adjacent to said gas inlet opening and said canister first section bottom edge is inserted into said retention clip such that said curved base section engages with said bottom edge and said planar section of said air bag retention clip is adjacent to one surface of said canister first section, wherein said air bag cushion is passed outwardly of said curved base section and back over the other surface of said canister first section, and fastener means are inserted through one of each of said second apertures, said fifth apertures, said fourth apertures, said first apertures and said third apertures thereby securing said air bag cushion onto said retention clip.

2. The device of claim 1 wherein said air bag retention clip is stitched to said air bag cushion.

3. The device of claim 1 wherein said air bag retention clip is made from a polymeric material.
