Abstract
An air bag device is provided which uses an eddy current position sensor. A coil of the sensor is disposed on a seat frame or the like, as a portion of a vehicle body, which is difficult to deform at the beginning of a collision. A metal body as a detected body of the sensor is disposed on a portion, facing the coil, of a rocker panel, which is a portion of the vehicle body, that is easily deformable at the beginning of a collision. The sensor may be disposed at other portions, e.g. inside a pillar or a door. An inductance of the coil influences a resonance condition of a resonance circuit. An output of the resonance circuit is rectified by a rectifier circuit. An ignition control circuit detects an output of the rectifier circuit and outputs an ignition command signal to a squib of an inflator, based upon at least one of an output value and a change rate of the output value of the rectifier circuit, thereby inflating an air bag.
