INFLATOR WITH ANNULAR CENTER GENERANT HOLDER

An airbag inflator (10) includes a pressure vessel (12), an initiator (14) positioned at one end of the pressure vessel, a manifold (16) positioned at an opposite end of the pressure vessel, and a generant holder assembly (22), secured in the pressure vessel adjacent the initiator. The generant holder assembly defines an annular space that is configured to secure a generant (36). 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.
