Publication number: 20020003344Abstract: Load sensors detect a load from seat and a sitting object. A load sensor control unit determines whether the detected load is greater or smaller than the predetermined load. If the detected load is smaller, the air bag operation is restricted. If the detected load is greater, and if A-ELR switch that detects the state of seatbelt retractor indicates the ALR state, the air bag operation is restricted. In this manner, even when the fastening force for installing the child seat to the seatbelt is large, it is possible to avoid an unwanted deployment of the air bag from a wrongful determination that an adult is sitting. The occupant protection apparatus can determine when a child seat is installed and when an adult is sitting, and restrict the deployment of the air bag when the child seat is being installed.Type: ApplicationFiled: May 17, 2001Publication date: January 10, 2002Inventor: Yoshinori Maeda
