Claim 19:
20. An airbag inflator comprising:
a lower pressure vessel supporting an initiator assembly;
an upper pressure vessel engaging the lower pressure vessel, the upper pressure vessel including an exit orifice sealed with a rupturable membrane;
an inert gas or gas mixture contained in the lower and upper pressure vessels;
a first pressure zone containing a generant, the first pressure zone comprising outlet vent openings through which combustion and stored gases exit;
a second pressure zone radially outward of the first pressure zone and functioning at an operating pressure lower than an operating pressure of the first pressure zone, wherein combustion and stored gases from the first pressure zone flow through the outlet vent openings into the second pressure zone;
a flow diverter disposed in the second pressure zone and including inlet vent openings, wherein the flow diverter is configured to direct the combustion and stored gases through the exit orifice;
a manifold secured over the upper pressure vessel, the manifold including manifold vents through which the combustion and stored gases from the exit orifice pass; and
a booster can centrally mounted in the lower pressure vessel within the first pressure zone and secured to the initiator assembly, wherein the booster can comprises directional vents such that combustion and stored gases from the booster can are not uniformly distributed in the first pressure zone.
