The inflator 13 provided in the roof side rail 11 of the vehicle is ignited by the detection of the impact force applied to the vehicle body in the vehicle width direction, and gas is flowed into the airbag 15, so that the airbag 15 is provided on the side of the vehicle body. It expands and deploys inside the window 17. In addition, the lower airbag device 9 includes the door 7
The inflator 19 provided inside ignites upon detection of an impact force in the vehicle width direction and causes gas to flow into the airbag 21, whereby the airbag 21 inflates inside the door 7,
expand. As a result, the occupant 23 is configured such that the head portion 23a is supported by the airbag 15 and the chest portion 23b is supported by the airbag 21 so as to be protected.

あった。By the way, when the window glass 25 of the window portion 17 is closed and an impact force in the vehicle width direction is applied due to a side collision or the like, the window glass 25 is damaged and the window portion side of the airbag 15 is closed. Even when the window glass 25 is opened, the sharp edge portion of the collision partner vehicle or object may come into contact with the side surface of the airbag 15 on the window portion side. For this reason, even if the side surface of the airbag 15 on the window side of the airbag 15 comes into contact with the damaged window glass 25 or the sharp edge portion of the vehicle or the other vehicle with which the vehicle collides, a hole is not formed in the airbag 15. The wall thickness had to be thick as a whole.
