Abstract
An air bag apparatus for a passenger seat has reduced deploying speed and reduces the impact of the air bag on an occupant moving forward at the time of a crash of a vehicle. A gas generator is disposed in a case of the air bag apparatus, extending in a fore-to-aft direction relative to the vehicle. The gas generator case contains a cylindrical inflator extending in the fore-to-aft direction. An air bag is disposed in the apparatus case, folded in a predetermined manner. An inner bag for controlling gas flow is disposed in the air bag, folded in a predetermined manner. An auxiliary inner bag is sewed to an outside surface of a bag of the inner bag. When the inner bag is inflated and deployed, the bag of the inner bag presses a portion of the air bag against the windshield, and the auxiliary inner bag presses another portion of the air bag against the instrument panel.
