INFLATOR WITH OPEN CENTER GENERANT HOLDER

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.
