Abstract
Systems and methods are disclosed in which a seal is formed between an interior of an airbag inflator base and an exterior environment. A polymeric member of a membrane seal can form a solid state bond with an overmold of an electrical connector of an initiator of an airbag inflator. Furthermore, an adhesive film of the membrane seal can bond to the airbag inflator base at a position disposed at least partially around a recess through which the overmold couples an initiator to the airbag inflator base.
Claims21
A membrane seal for an airbag inflator, the membrane seal comprising:
- a substrate forming an aperture to correspond to one or more of a recess and an aperture of a base of an airbag inflator;
- and
- an adhesive configured to bond the membrane seal substrate to an exterior surface of the base such that the membrane seal is disposed around at least a portion of the aperture of the base of the airbag inflator, and wherein the aperture receives at least a portion of an initiator.
A sealed airbag inflator, comprising:
- a base;
- an initiator at least partially disposed within the base;
- an overmold coupling the base to the initiator;
- and
- a membrane seal comprising a substrate and an adhesive, the membrane seal coupled to the base via the adhesive, and the substrate coupled to the overmold such that the membrane seal forms a seal between the base and the overmold.
