<P>PROBLEM TO BE SOLVED: To provide a air bag device for protecting a pedestrian capable of shortening the time from the beginning of inflation to the completion of the inflation of the air bag as short as possible. <P>SOLUTION: The air bag device M1 for protecting the pedestrian has a control unit 17, the air bag 20, an inflator 22, a moving unit 30 of a cover material 27 for making the release out of the air bag 20 from an receiving area 25 smooth, and an extracting unit 34 for the air bag 20. The control unit 17 is constructed so as to be able to detect two stages of detection consisting of contact detection capable of predicting the contact of a vehicle V with the pedestrian and approaching detection detecting the approach of the pedestrian prior to the contact detection corresponding to input signals from a sensor. The moving unit 30 and the extracting unit 34 are operated by the control unit 17 having detected the approach of the pedestrian. The inflator 22 is operated by the control unit17 having detected the contact with the pedestrian. <P>COPYRIGHT: (C)2004,JPO |
