ABSTRACT:
An apparatus (14) for inflating an inflatable vehicle occupant restraint (12) comprises means (22) defining an elongated combustion chamber (30) having opposed ends (24, 26). The combustion cheer (30) contains a mass (32) of gas generating material. An igniter (92) is positioned at one end of the combustion chamber (30) for igniting the mass (32) of gas generating material. The mass of gas generating material provides a substantially continuous burn path for the full length of the combustion chamber (30). The mass of gas generating material comprises at least one expansion area (124) between the combustion chamber opposed ends (24, 26), which expansion area is essentially free of gas generating material. The expansion area (124) has a free volume which is effective to attenuate pressure waves within the combustion chamber.
