Gas generating apparatus for inflating air bag
First Claim
1. A gas generating apparatus for inflating an air bag, comprising:
- a housing body (1) having opposite sides, one of which opens toward an air bag when a portion (6) of the body is connected to such air bag;
a combustion chamber (9) formed centrally within said housing body, wherein high-pressure gas is generated upon combustion of a gas generating agent contained within the body;
the housing body having a partition (12) which forms a mixing chamber (15) in ring-like configuration concentrically disposed so as to be spaced apart from a discharge (15a) opening of said housing body by a desired interval, said combustion chamber communicating with said mixing chamber whereby said high-pressure gas from said combustion chamber is introduced into said mixing chamber;
a nozzle (16) of ring-like configuration provided wherein said housing body for ejecting said high-pressure gas flowing from said combustion chamber toward an entrance opening of said mixing chamber formed by said partition; and
an air intake means (5) formed in said housing body in close proximity to said nozzle and opening from the side of the housing body opposite from such air bag, whereby said high pressure gas ejected by said nozzle causes air to be drawn through said air intake means into said mixing chamber and mixed therein with said high-pressure combustion gas for cooling thereof.

Abstract
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.
