ABSTRACT:
A gas generator for air bags is provided which includes a first outer shell and a second outer shell, each having a circular part and an outer wall formed along the outer periphery of the circular part. A gas generating device is installed in the hollow portion formed within the outer shells. Openings for communicating the hollow portion with an air bag are provided. A plurality of concentric wall members axially extending from the circular part of the first outer shell and a plurality of concentric wall members axially extending from the circular part of the second outer shell, located at positions corresponding to the outer wall members of the first outer shell define circumferential chambers within the gas generator. Gaps are formed between terminal end surfaces of opposing outer wall members whereby gases produced by the gas generating device on receiving impacts flow through the generator and are introduced into the air bag to protect a passenger from impacts.
