Gas generator for air bag and air bag system
First Claim
1. A gas generator for an air bag, comprising:
- a housing having at least one gas discharge port;
igniting means that is actuated when an impact sensor detects an impact;
solid bodies of gas generating agent that are ignited by the igniting means and burned to generate a combustion gas; and
coolant-filter means for cooling the combustion gas and scavenging combustion residues, said igniting means, said gas generating agent and said filter means being accommodated in said housing, whereina ratio (A/At) of a total surface area A of said solid bodies of gas generating agent to a total opening area At of said at least one gas discharge port is limited to be larger than 300.

Abstract
A gas generator for an air bag which enables a gas generating agent to be completely burned in a desired period of time, and shows sufficient operating characteristics is provided.
In a gas generator for an air bag, wherein igniting means to be actuated when an impact sensor detects an impact, solid bodies of gas generating agent ignited by the igniting means and burned to generate a combustion gas, and filter means for cooling the combustion gas and scavenging combustion residues are accommodated in a housing having gas discharge ports. The ratio (A/At) of the total surface area A of the solid bodies of gas generating agent to the total opening area At of the gas discharge ports is controlled to be larger than 300.
