Patent ID: 7441624

Claim:
A passenger restraint device of a motor vehicle, comprising: a plurality of predicting devices each being able to predict or detect a collision of the vehicle with an obstacle in front of the vehicle; a sensitivity adjusting device that is able to adjust a sensitivity of at least one of the predicting devices; reversible passenger restraining devices that are able to reversibly restrain a passenger in the vehicle; non-reversible passenger restraining devices that are able to non-reversibly restrain the passenger in the vehicle; and a control unit that, based on a signal from the one of the predicting devices that has been subjected to the sensitivity adjustment by the sensitivity adjusting device, controls operation of the reversible and non-reversible passenger restraining devices, in which when one of the predicting devices predicts or detects the collision of the vehicle with the obstacle, the sensitivity adjusting device adjusts the sensitivity of at least one of the predicting devices, in which when one of the predicting devices predicts or detects the collision of the vehicle with the obstacle, the sensitivity adjusting device adjusts the sensitivity of at least one of the predicting devices that is other than the predicting device that has predicted or detected the vehicle collision, wherein the sensitivity is adjusted by changing the range of the at least one of the predicting devices that is other than the predicting device that has predicted or detected the vehicle collision.
