Abstract
A propellant grain retainer for an air bag inflator having a pressure vessel. A cantilevered finger is mounted in the pressure vessel and a propellant grain is mounted thereon. Upon assembly of the pressure vessel, the finger is deformed inwardly away from an adjacent wall of the pressure vessel to increase the air gap between the pressure vessel wall and the propellant grain to reduce heat transfer therebetween and increase the safety of the inflator.
