    Patent number: 5437470
    Abstract: A lid structure for an air bag system capable of preventing passengers on a vehicle from injuring themselves by inflating an air bag when the vehicle crashes. The lid structure includes a main opening and a sub opening through which the air bag can inflate outside of an instrumental panel. A main lid is provided for closing the main opening and a sub lid is provided for closing the sub opening. The sub lid is formed from a weakened part of the instrumental panel and is easily broken by the inflating force of the air bag.
