Abstract
An air bag for use in connection with a gas generator is provided. The air bag is of a double-wall construction. The air bag is fitted to the housing of a gas generator and a gas jet opening for allowing the air bag to communicate with the housing is provided. A gas generated by the gas generator due to an impact is charged into the air bag. The air bag has a double-wall structure including a first air bag and a second air bag having a greater capacity than the first air bag disposed about and attached to the first air bag. The first air bag constitutes an air storage chamber which receives air from the atmosphere through an air intake path and stores the air. A gas storage chamber is formed between the first and second air bags which receives a combustion gas from the gas jet opening and temporarily stores the combustion gas. The air intake path is typically a hollow path between the atmosphere and the air storage chamber. The first air bag has an opening therein which establishes communication between the gas storage chamber and the air storage chamber.
