Method of inflating air bag

An inflator comprising an inflator housing in which a pressurized medium for inflating an air bag is charged and an opening is formed at one end thereof, a diffuser portion which is fixed to the opening side of the inflator housing and is provided with a gas discharging hole for discharging the pressurized medium from the opening to the outside at actuation, a rupturable plate closing an outflow path for the pressurized medium between the opening of the inflator housing and the diffuser portion, an igniter provided at the diffuser portion to serve as a rupturing means for the rupturable plate, and a gas discharging port connected to the gas discharging port of the diffuser portion to serve as a discharging passage for the pressurized medium, wherein a sealing agent is disposed inside or outside of the inflator.

An inflator comprising an inflator housing, a gas generator which is accommodated in the inflator housing and is provided with a gas generating means, an igniting means chamber provided with an igniting means connected to the gas generator, and a pressurized medium including an inert gas charged in the inflator housing, wherein a sealing agent is disposed inside or outside of the inflator.

An inflator comprising, in a housing having a gas discharging hole, an igniting means including an igniter to be actuated by the impact and a transfer charge, and a gas generating means which is to be ignited/burnt by the igniting means to generate a combustion gas for inflating an air bag, wherein a sealing agent is disposed outside the inflator and in a state of contacting the gas discharging hole of the housing.

An inflator according to any one of claims 17 to 25, wherein the sealing agent has a boiling point higher than a temperature when the inflating gas is discharged.
