Gas generating apparatus for inflating air bag
First Claim
1. A gas generating apparatus for use in inflating an air bag, comprising:
- a housing body with a cylinder portion having an open end, a base member comprising a wide flange connected to said open end of said cylinder portion and a cylindrical joint portion which is larger in diameter than said cylinder portion and projects concentrically away therefrom;
a cover member in a cap-like form which is detachably screwed inside said cylindrical junction portion of said base member;
an air intake opening with a large diameter which is formed at the center of said cover member along an axis thereof;
a mixing chamber which is disposed at the center of said housing body, connected to said air intake opening in alignment with said axis, and for connected to the inside of an air. bag;
a combustion chamber which is formed inside said housing body on the inside of the outer periphery thereof and which generates a high-pressure gas upon combustion of a gas generating agent; and
a multiplicity of nozzles around the entire circumference of a junction portion between said air intake opening and said mixing chamber which eject said high-pressure gas from said combustion chamber toward an opening of said mixing chamber at high speed.

Abstract
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.
