ambient temperature in the region of 30 u00b0 c when the ambient temperature is in a range intermediate such extreme cold and extremely hot 85 u00b0 c the orifices 28 of the second plurality of orifices open as the pressure within the inflator 22 increases and ruptures the rupturable foil 32 to direct gas rearwardly into the air bag not shown if the ambient temperature becomes very high reaching and exceeding 85 u00b0 c the orifices 34 of the third plurality of orifices open as the pressure in the inflator 22 increases and ruptures the rupturable foil 36 to direct gas forwardly away from the air bag not shown and into the surrounding environment that is either into the compartment of the automotive vehicle or into a duct for transmission externally thereof the use of rupturable foil 36 of increased thickness allows the use of larger orifices 34 than the orifices 16 in the inflator assembly 10 of the prior art described hereinbefore the use of larger orifices 34 an occupant inflatable restraint system 38 constructed in accordance with the present invention is illustrated in fig5 and 6 in an inactive condition being mounted on the dashboard of an automotive vehicle the restraint system includes a rigid metal reaction.
