Abstract

An inflator of the present invention is a hybrid type inflator in which an inside of a housing is charged with a pressurized gas and a gas generating agent capable of generating a gas at time of combustion. In the inflator of the present invention, a quantity of heat generated by the gas generating agent at the time of the combustion is set within a range of 6,000 to 10,000 J/g, and a molar ratio of the pressurized gas and the combustion gas generated by the combustion of the gas generating agent is set within a range of 80 to 130.

Claims

1. An inflator that is a hybrid type inflator in which an inside of a housing is charged with a pressurized gas and a gas generating agent capable of generating a gas at time of combustion, wherein:

a quantity of heat generated by the gas generating agent at the time of the combustion is set within a range of 6,000 to 10,000 J/g; and

a molar ratio of the pressurized gas and the combustion gas generated by the combustion of the gas generating agent is set within a range of 80 to 130.
