Abstract
A gas generator for an air bag, which enables a gas generating agent to be completely burned within a desired period of time, and shows sufficient operating characteristics, is provided. In a housing of the gas generator for an air bag, having gas discharge ports, igniting means to be actuated when an impact sensor detects an impact, solid bodies of gas generating agent to be 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 such a gas generator, 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.
