An air bag inflator having a plurality of gas exit orifices of three different sizes arranged so as to provide thrust neutral operation maintains air bag performance at the same level over the temperature range of ambient to +85°C., directing all of the generated gases into the air bag at ambient temperature, but allowing a portion of the gases to be directed away from the air bag at +85°C.

An inflator for generating gas for inflating a vehicle occupant restrain, said inflator comprising, an elongated housing, said housing having a first plurality of orifices and a second plurality of orifices for directing gas generated by said inflator into the restraint and a third plurality of orifices for directing gas directed by said inflator away from the restraint, wherein said housing has a longitudinal axis, wherein said first plurality of orifices and said second plurality of orifices are distributed on opposite sides of said housing along a first portion along the length thereof with the orifices of each of said first plurality of orifices and of said second plurality of orifices being positioned in a plane individual thereto that passes through the longitudinal axis of said housing, and wherein said third plurality of orifices are uniformly distributed in at least one row around the periphery of a second portion of said housing adjacent an end thereof, means covering said first plurality of orifices, said second plurality of orifices, and said third plurality of orifices which ruptures at a first predetermined pressure to allow gas to flow into the restrain through said first plurality of orifices, which ruptures at a second predetermined pressure higher than said first predetermined pressure to allow gas to flow into the restraint through said second plurality of orifices, and which ruptures at a third predetermined pressure higher than said first and second predetermined pressures to allow gas to flow away from the restrain through said third plurality of orifices, with the orifices of the first, second and third plurality of orifices being so positioned with respect to said housing as to provide a thrust neutral configuration.
