ABSTRACT:
An apparatus and method suitable for use in inflating a vehicle occupant restraint are provided. The apparatus stores a gas generating material in a first chamber and stores a supply of gas under pressure in a second chamber. When ignited, the gas generating material produces a hot gas which contains particulate material. To effect particulate removal, housed within the container and extending about the gas exit nozzle of the first chamber is a filter structure. The filter structure forms inner and outer mixing zones within the second chamber wherein portions of the stored gas mix with the appropriately generated and/or treated gas, forming inflation gas. The inflation gas in turn is passed through a diffuser and into the vehicle occupant restraint.
