Abstract
A hybrid inflator comprises an inflator housing which contains a pressurized medium and a gas generator housing. The gas generator housing is interconnected with the inflator housing. The gas generator housing comprises a first chamber which contains a propellant, a propellant ignition assembly, a second chamber which is fluidly interconnected with the first chamber and the inflator housing for combusting propellant gases generated by the ignited propellant with the pressurized medium, an outlet port which is arranged on the gas generator housing to provide the pressurized medium and propellant gasses from the second chamber to the air/safety bag, and a main closure disk which normally blocks the outlet port and is ruptured after ignition of the propellant. The first and second chambers and the main closure disk are arranged in that order on a common longitudinal axis of the inflator. The gas generator housing comprises at least one bleed port for substantially equally maintaining internal pressures of the inflator housing and the first chamber.
