Abstract
A hybrid inflator for an automotive inflatable safety system is disclosed. In one embodiment, the inflator includes a stored gas housing and a gas generator housing. Propellant grains are contained within the gas generator and an appropriate pressurized medium is contained within the stored gas housing. Generally, the pressurized medium flows through the gas generator or an extension thereof when exiting the inflator to the air/safety bag to enhance the mixing of the pressurized medium with the propellant gases. Moreover, a rapid pressurization of a region proximate the main closure disk is used such that fluid pressure acts directly on the disk to open the same and initiate flow to the air/safety bag.
