Abstract:
1. A gas generator comprising: a housing having a first end, a second end, an opening in said first end for fluid flow into said housing, and an inner peripheral wall defining a plenum, said first end fluidly communicating with a pressurized gas supply upon gas generator activation thereby supplying pressurized fluid flow through the housing; a gas supply seal for sealing the pressurized gas supply prior to gas generator activation; a retainer seal positioned within said opening to support said gas supply seal against a force exerted thereon by a pressurized gas; a notched support member fixed within said plenum and against said first seal thereby preventing pressurized fluid flow prior to gas generator activation; and an initiator fixed within said housing and fluidly communicating with said plenum upon gas generator activation, wherein upon gas generator activation, said initiator creates a force sufficient to fracture said notched support member thereby releasing pressurized gas into said first end.
