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.

A hybrid inflator for an automotive inflatable safety system comprising an air/safety bag, said inflator comprising: an inflator housing which contains a pressurized medium; a gas generator comprising a gas generator housing, a propellant contained within said gas generator housing, at least one gas generator inlet port which fluidly interconnects said gas generator housing and said inflator housing, and at least one gas generator outlet port which fluidly interconnects said gas generator housing and the air/safety bag; a propellant ignition assembly interconnected with said gas generator; and valve means, operatively associated with said at least one gas generator inlet port, for substantially inhibiting flow between said inflator housing and said gas generator housing through said at least one gas generator inlet port until a pressure within said inflator housing exceeds a pressure within said gas generator housing by a predetermined degree.
