Abstract
An air bag apparatus in a tire air pressure sensing system for a vehicle capable of reliably protecting passengers of the vehicle from accidents regardless of the pattern of the accident which includes a collision sensing section, a pressure sensing section, a receiving section, an Electronic Control Unit, a warning section and an air bag actuating section. The collision sensing sections has first and second collision sensors, and pressure sensing section has pressure sensors and radio transmitters. The warning section has sound and visual warning units, and air bag actuating section has an inflatable air bag and an inflator. Here, the air bag is operated when the first collision sensors monitor the shock at least a first shock value, or the second collision sensors monitor the shock at least the second shock value while the pressure sensors monitor a pressure below a pressure value presented by a no-load state of an air pressure in the tire.
