Abstract
An airbag inflator includes a pressure vessel, an initiator positioned at one end of the pressure vessel, a manifold positioned at an opposite end of the pressure vessel, and a generant holder assembly secured in the pressure vessel adjacent the initiator. The generant holder assembly defines an annular space that is configured to secure a generant. A center of the generant holder assembly is open. The open center allows a pressure wave from the initiator to travel to the outlet burst disk.
Claims19
An airbag inflator comprising:
- a pressure vessel defining an outside diameter of the airbag inflator;
- an initiator positioned at one end of the pressure vessel;
- a manifold positioned at an opposite end of the pressure vessel;
- and
- a generant holder assembly secured in the pressure vessel adjacent the initiator and directly engaging an interior wall of the pressure vessel, the generant holder assembly defining an annular space with the interior wall of the pressure vessel that is configured to secure a generant, wherein a center of the generant holder assembly is open.

An airbag inflator comprising:
- a pressure vessel defining an outside diameter of the airbag inflator;
- an initiator positioned at one end of the pressure vessel;
- a manifold positioned at an opposite end of the pressure vessel;
- a generant holder secured in the pressure vessel adjacent the initiator, the generant holder including a tubular body and an annular ledge, the annular ledge having a larger diameter than the tubular body and being sized to be press fit into the pressure vessel, the generant holder defining an annular space between the tubular body and an interior wall of the pressure vessel, wherein a center of the generant holder is open to a downstream portion of the pressure vessel prior to and after initiation of the airbag inflator;
- a generant positioned in the annular space and engaging the annular ledge;
- and a generant cover secured in the pressure vessel over the tubular body of the generant holder, the generant cover being selectively positioned to engage and secure the generant in the annular space.
