Abstract
The present invention provides an inflator capable of prolonging the duration of inflation of an air bag. Since an inflator housingof an inflatorfor a curtain air bag is charged with a pressurized medium comprising a mixed gas of He and Ar (He:Ar=3:7 to 7:3), the sound velocity of the pressurized medium is smaller than that of a pressurized medium comprising He only, and the viscosity of the former is higher than that of the latter, so that the duration of the inflation of an air bag can be prolonged.
