Description of Invention (丨) [Technical Field of Invention] The present invention relates to an inflatable safety system for automobiles, and more specifically, it relates to an airbag that can be inflated rapidly. In addition, a hybrid inflator that can be made more compact and lighter and an airbag device using the same are used. [Previous Technology] With the development of inflators for inflatable safety systems of automobiles and vehicles, a hybrid inflator using a pressurized gas and a solid gas generating agent has attracted attention. In addition to the hybrid inflator, its main design is to make the airbag act effectively, and it is necessary to inflate the prescribed amount at a prescribed time. For its structure, there have been various proposals. As a prior art, there is JP 8 -282427, EPO 844148, USP 5,351,988, USP 5,882,036, USP 5,851,027, USP 3,868,124, 113 to 3,758,131, etc. are known. In addition, the hybrid inflator is intended for an automobile vehicle, and in particular, the size of the inflator that affects the weight of the automobile vehicle becomes an important design issue. Therefore, this point also needs to be considered. However, in the conventional hybrid inflator using a pressurized gas and a solid gas generating agent, the above-mentioned design issues may not be sufficiently satisfied. For example, when the internal pressure is increased by the combustion heat of a solid gas generator, and when a pressurized gas is used to inflate an airbag, it is necessary to increase the wall thickness of the casing in order to improve the pressure resistance. Furthermore, when oxygen is contained in the pressurized gas, there is a lack of weight increase due to only the amount of oxygen. In addition, there is also a gas generator using perchlorate. As a pressurized gas, it is a hybrid inflator constructed without oxygen. It is available in many paper sizes in accordance with the Chinese National Standard (CNS) A4 (210 X 297).

Description of the Invention (L), the combustion of gas generating agents is deficient in the generation of harmful little things to passengers. In addition, the solid gas generating agents used previously are mainly guns such as R DX [Inspiration of the present invention] The object of the present invention is to provide a hybrid inflator that is more lightweight and miniaturized without reducing the function as an inflator, and an airbag device using the same. As a solution, the present invention provides a hybrid inflator provided with an airbag of an inflatable safety system of a vehicle, which has an inflator housing; a gas generator housed in the inflator; and an ignition connected to the gas generator. Device room, characterized in that the inflator shell is filled with inert A pressurized medium containing no oxygen is a gas generator having one or two or more gas generating chambers including a gas generating device, the amount of the pressurized medium (A mole) and the gas generated by the combustion of the gas generating device The molar ratio (A / B) of the amount (B mole) is 8/2 to 1/9. In this way, the amount of the pressurized medium filled in the hybrid inflator is adjusted with the amount of the gas generating agent. The molar ratio of the amount of gas produced by combustion can reduce the charge of the pressurized medium, and therefore, the volume of the shell [ie, the length and / or width (diameter) of the shell is reduced] will not increase. The filling pressure of the pressurized medium (= the internal pressure of the casing) can be maintained at the same pressure as before the volume reduction. OA / B is preferably 8/2 ~ 3/7. 尙, the hybrid inflator in the present invention The weight ratio of the pressurized medium (a) to the weight of the gas generating device (b) is in accordance with the Chinese National Standard (CNS) A4 specification (210 X 297 mm).
