<P>PROBLEM TO BE SOLVED: To provide a curtain air bag device configured in such a way that a curtain air bag capable of inflation and deployment is subjected not only to the inflating force of the curtain air bag body section but also to the biasing force caused by the inflation of a gas introduction section, with the consequence that a roof lining is pushed open toward the interior of a vehicle, resulting in the curtain air bag being inflated and deployed in the interior of the vehicle. <P>SOLUTION: The gas introduction section 1b is folded up on a side surface of that portion of a folded body of the curtain air bag body section 1A which is on the side of a roof side section 10. If a side of the vehicle is collided with or if the vehicle turns over, an inflator 3 is activated in such a way as to emit gas, the gas is supplied to the curtain air bag 1, and the curtain air bag 1 starts to inflate. In this case, the gas from the inflator 3 first flows into the gas introduction section 1b, thereby inflating the gas introduction section 1b. Due to the above, the inflating force of the folded body of the curtain air bag body section 1A and the inflating pressure of the gas introduction section 1b are superimposed on each other, and press the lower edge of a roof side garnish 11 inward toward the interior of the vehicle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
