Abstract
A collision detecting apparatus (1) comprises a pair of deformation sensor (2) and G sensor (3) having output signals to be supplied to a control circuit (19). When a door outer panel (18) is deformed by collision of a vehicle, the deformation sensor (2) is turned on. Meanwhile, the door, when received an impact force, will be subjected to a large G sufficient to turn on the G sensor (3). Thus, the control circuit (19) generates an actuation signal for exploding an air bag only when the sensors (2) and (3) generate ON signals. However, when the door outer panel (18) is manually pushed or swung for opening/closing operation, only one of these two sensors (2) and (3) is turned on. Hence, the control circuit (19) does not generate the actuation signal, thereby surely detecting the collision of the vehicle and preventing the air bag from being erroneously exploded.
