Abstract
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.
