Abstract
An inflator according to this invention has a structure that an interior part of a housing is charged with a pressurized gas and a gas generating agent capable of generating a gas when combusted, wherein the pressurized gas formed only of an inert gas; a quantity of heat to be generated when the gas generating agent is combusted is set within a range of 6000 to 10000 J/g; and a molar ratio between the pressurized gas and the combustion gas generated by the combustion of the gas generating agent is set within a range of 20 to 40.
Claims5
A hybrid inflator for injecting expanding gas formed of a pressurized gas and a combustible gas, the hybrid inflator comprising a housing made of metal including a chamber in which the pressurized gas is charged, a gas injection opening, a gas generating agent containing metal powder capable of generating the gas when combusted and a squib,
- wherein a first side of the chamber is closed with a first bursting plate facing the gas generating agent and the squib, and a second side of the chamber is closed with a second bursting plate facing the gas ejection opening;
- the pressurized gas consists of an inert gas;
- a quantity of heat to be generated when the gas generating agent is combusted is set within a range of 6000 to 10000 J/g;
- and
- a molar ratio between the pressurized gas and the combustion gas generated by the combustion of the gas generating agent is set within a range of 20 to 40.
