Occupant restraint module

Claim 2

An occupant restraint module comprising an inflator, a folded air bag, a support member having the inflator and the folded air bag mounted thereon and having a peripheral edge defined by a plurality of tabs spaced there along and projecting away from the air bag, a box-like cover assembly for covering the cushion and support member and including a base wall and side walls depending from the base wall and having an in-turned flange having a plurality of slots spaced therealong in matching alignment with the tabs of the support member, and said tabs projecting from the support member having a length sufficient to extend through and beyond the slots of the cover assembly flange whereby the cover assembly is mounted on the support member by installing the flange of the cover over the support member with each one of the plurality of slots receiving a complementary one of the tabs of the support member and the tabs being crimped to permanently retain the cover assembly on the support member.

Claim 3

An occupant restraint module comprising an inflator, a folded air bag inflatable by the inflator, a support member having the inflator and the folded air bag mounted thereon and having a peripheral edge including a return bent flange defining an inner leg and an outer leg spaced apart by a bight portion, said outer leg having a plurality of tabs spaced therealong and projecting away from the air bag, a box-like cover assembly for covering the cushion and support member and including a base wall engageable by the folded cushion to forcibly compress the folded cushion against the support member to reduce the normal thickness thereof and side walls depending from the base wall and having an in-turned flange engaging with the inner leg and having a plurality of slots spaced therealong in matching alignment with the tabs of the support member, whereby the cover assembly is mounted on the support member by applying a compressive force to the folded cushion to compress the cushion and enable movement of the cover toward the support member and installation of the flange of the cover over the support member with each one of the plurality of slots receiving a matching one of the tabs of the support member and so that the self expansion force of the cushion tending to return the cushion to normal thickness upon removal of the compressive force causes the cover to remain mounted on the support member, and said tabs projecting from the support member having a length sufficient to extend through and beyond the slots of the cover assembly flange to enable crimping of the tabs to permanently retain the cover assembly on the support member.

Claim 4

An occupant restraint module comprising an inflator, a folded air bag inflatable by the inflator, a support member having the inflator and the folded air bag mounted thereon and having a peripheral edge including a return bent flange defining an inner leg and an outer leg spaced apart by a bight portion, said outer leg having a plurality of tabs spaced therealong and projecting away from the air bag, a box-like cover assembly for covering the cushion and support member and including a base wall engageable by the folded cushion to forcibly compress the folded cushion against the support member to reduce the normal thickness thereof and side walls depending from the base wall and having an in-turned flange engaging with the inner leg and having a plurality of slots spaced therealong in matching alignment with the tabs of the support member, whereby the cover assembly is mounted on the support member by applying a compressive force to the folded cushion to compress the cushion and enable movement of the cover toward the support member and installation of the flange of the cover over the support member with each one of the plurality of slots receiving a matching one of the tabs of the support member and so that the self expansion force of the cushion tending to return the cushion to normal thickness upon removal of the compressive force causes the cover to remain mounted on the support member, and said tabs projecting from the support member having a length sufficient to extend through and beyond the slots of the cover assembly flange to enable crimping of the tabs to permanently retain the cover assembly on the support member.
