Abstract
A gas generating system (10) includes a housing (12), a first end closure (22) secured to the housing (12) for hermetically sealing a first end portion of the housing, and a first bore seal (26) formed separately from the first end closure (22) and secured to the first end closure (22) for mounting a first gas generant combustion initiation mechanism (24) therein. The gas generator (10) may include single-stage and/or dual-stage capability.
Claims22
A gas generating system comprising:
- a housing;
- a first end closure secured to the housing for hermetically sealing a first end portion of the housing;
- and
- a first bore seal formed separately from the first end closure and secured to the first end closure for mounting a first gas generant combustion initiation mechanism therein,
- wherein the bore seal is insertable into an opening in the end closure after the end closure is secured to the housing,
- and wherein a portion of the end closure is slidably engaged with a portion of the housing to position the portion of the end closure within the housing prior to securement of the first end closure to the housing.
