<P>PROBLEM TO BE SOLVED: To provide a vehicle provided with an air bag device for back collision capable of preventing an interference of the air bag to the head of a crew seated on the rearmost seat at the time of expansion/development when the back collision occurs on the vehicle. <P>SOLUTION: A swirl part is provided by winding a lower air bag 21A provided corresponding to a rear window glass at a rear end of the vehicle to a swirl shape. This swirl part is stored in a bag storage case 23. When the inflator 22 is operated and an expansion gas is fed to the lower air bag 21A, the swirl part is expanded/developed while being unwound. At this time, since the swirl part is developed along an inner surface of the rear window glass 18 in the unwinding process, the lower air bag 21A is not interfered to the head of the crew seated on the rearmost seat and the expansion/development action of the lower air bag 21A is appropriately and rapidly carried out. <P>COPYRIGHT: (C)2004,JPO |
