A gas generating apparatus for inflating an air bag which comprises a housing with an open joint portion connecting to the air bag and having a combustion chamber formed at the center inside the housing body wherein a high pressure gas is generated upon combustion of a gas generating agent. A partition is provided which defines a mixing chamber in a ring-like configuration by being concentrically disposed so as to be spaced apart from the opening of the housing body by a pre-selected interval whereby the high pressure gas forming a combustion chamber is introduced into the mixing chamber. A nozzle formed in a ring-like configuration is provided at the high pressure gas introducing portion so that the high pressure gas is ejected toward the opening of the mixing chamber and an air intake portion is formed along the nozzle on the housing body.

Gas generating apparatus for inflating air bag

A gas generating apparatus for inflating an air bag is provided which comprises a housing body with an air intake opening of large diameter formed at the center of the housing body. Along an axis, there is a mixing chamber disposed at the center of the housing body and connected to the air intake opening with the axis and also connected so as to open into the air bag. A combustion chamber is formed inside the housing body on the inner side of the outer periphery thereof and generates a high-pressure gas upon combustion. There is a multiplicity of nozzles around the circumference of a junction portion between the air intake opening and the chamber which ejects the high pressure gas from the chamber toward an opening of the mixing chamber at high speed.
