First Claim
1. A gas generator for an air bag including two gas generating units being connected in an axial direction, each of said gas generating units comprising:
- a cylindrical housing;
ignition means disposed in said cylindrical housing and operates upon receiving an operation signal;
a gas generating agent ignited by said ignition means to generate a combustion gas;
a pressurized gas sealed within said housing and heated by the combustion gas of said gas generating agent to generate a mixture gas together with said combustion gas; and
a diffuser having a gas exhaust outlet disposed at one end of said housing and from which said mixture gas in said housing is injected, said diffuser having a flat end wall portion, wherein said two gas generating units are joined by adjoining flat end wall portion of each of the gas generating units together and welding said diffuser of each of said gas generating units together.

Abstract
A gas generator for an air bag that can change deployment pattern of the air bag is provided. The gas generator includes two gas generating units connected in the axial direction, each of the gas generating units including a cylindrical housing, an igniter disposed in the cylindrical housing and operates upon receiving an operation signal, a gas generating agent ignited by the igniter to generate a combustion gas, a pressurized gas sealed within the housing and heated by the combustion gas of the gas generating agent to generate a mixture gas together with the combustion gas, and a gas exhaust outlet disposed at one side end of the housing and from which the mixture gas within the housing is injected. The two gas generating units are joined by welding one end of each of the housings of the gas generating units together.
