Abstract
A bore seal includes a polymeric interface portion adapted for coupling so an initiator activation signal transmission medium, and an initiator-receiving portion adapted for receiving an initiator therein. The bore seal generally houses a pyrotechnic initiator or igniter therein, for incorporation into a gas generating system or other system having a pyrotechnically actuatable element.
Claims8
A bore seal assembly comprising:
- a bore seal including an initiator-receiving portion adapted for receiving an initiator assembly therein and a polymeric interface portion adapted for coupling to an initiator activation signal transmission medium;
- an initiator assembly received in the initiator receiving portion, and;
- a retaining member separate from the bore seal and from the initiator assembly, the retaining member including at least a portion thereof inserted between the bore seal and the initiator assembly and providing an interference fit between the retaining member and the bore seal and between the retaining member and the initiator assembly, to secure the initiator assembly within the initiator receiving portion.
A bore seal assembly comprising:
- an initiator-receiving portion adapted for receiving an initiator therein;
- a polymeric interface portion adapted for coupling to an initiator activation signal transmission medium;
- and
- at least one resilient portion adapted to resiliently deflect responsive to movement of an initiator in a direction into the initiator-receiving portion, to admit the initiator into the initiator-receiving portion, the at least one resilient portion also being adapted to return to a substantially undeflected position after the initiator is received in the initiator-receiving portion;
- and a reinforcing member supporting the at least one resilient portion after the initiator assembly is received in the initiator receiving portion, to substantially prevent deflection of the at least one resilient portion after the initiator assembly is received in the initiator receiving portion.
