An inflator for an air cushion including a pressure vessel comprising a hollow sleeve for storing a quantity of inert gas such as Argon. One end of the sleeve is closed by a first pyrotechnic actuator assembly while the other end of the sleeve may include a closed end or another pyrotechnic actuator assembly. The pressure vessel is secured within a diffuser which directs inflation gases into the air cushion. The pressure vessel in cooperation with the diffuser defines various regions which assist in reducing the gas turbulence and heat transfer between the gas and the diffuser.

An inflator for an air cushion or bag comprising: a hollow, cylindrical sleeve having first and second ends; first means for enclosing the first end of the sleeve; second means for enclosing the second end (28) of the sleeve, the sleeve, and first and second means comprising a pressure vessel for storing a quantity of pressurized inert gas used to inflate the air bag; the first means comprises an initiator housing assembly comprising a manifold adapted to be secured to the sleeve at the first end including a flat edge first orifice, a first frangible member comprising a first rupturable disk secured about the first orifice, wherein one side of the disk is exposed to the stored gas; the manifold further including first flow control means, positioned remote from the pressure vessel for regulating the flow of inflation gas as it exits the pressure vessel and a pyrotechnic first actuator means for breaking the first frangible member wherein the initiator housing assembly, includes an initiator housing secured to the manifold assembly remote from the gas in the pressure vessel, the initiator housing comprises a hollow, necked-down portion, the first actuator means is removably received in the housing and closely spaced to the disk so that upon activation of the pyrotechnic actuator means the disk is ruptured by a shock wave to initiate flow of the inflation gas through the first orifice and first flow control means.
