時間が遅くなることが考えられる。However, in this airbag device with integrated head and chest, the head airbag 104 inflates later than the chest airbag 102, so that the head airbag is inflated. When the bag 104 is unfolded, the shoulders and arms of the occupant 112 and the side of the passenger compartment, that is,
The gap between the door trim of the side door and the pillar garnish of the center pillar may be reduced. For this reason, when the airbag bag for head 104 is deployed, it may interfere with the shoulders and arms of the occupant 112 or the side of the passenger compartment side, and the deployment completion time may be delayed.

In an airbag device integrated with a thoracic head, the head airbag bag protecting the head is communicated with the head airbag bag through a circulation hole provided in a partition cloth, the head airbag bag faces downward. Into the bag body along the two fold lines, and the chest airbag bag body is folded into the bag body at a fold line connecting a front end of the partition cloth and a rear lower end of the chest airbag bag body. It is characterized in that it is folded, then further folded into a bag body at a predetermined folding line, and finally folded in a bellows shape and stored in a case.

The deployment of the head airbag bag can be completed in a short time as compared with an airbag bag obtained by simply folding the airbag bag for the bellows and rolling the head airbag bag. Furthermore, also in the chest airbag bag body, since the bag body is folded into the bag body, that is, so-called cactus fold, the bag body comes out from the inside of the bag body at the time of deployment. There is little interference with the occupant and the side inside the vehicle compartment, and the airbag bag for the chest deploys quickly.

As shown in (A), the portion 18A above the fold line L1 is folded downward along the fold line L1 substantially at the center in the vertical direction of the head airbag body 18 from the deployment position shown by the solid line. It is folded inside the body to the position shown by the broken line in FIG. 1 (B) and the upper part 18 folded inside the bag body.
A fold line L2 along the fold line L2 substantially at the center in the vertical direction of A
Since the upper part 18B is folded downward from the position shown by the solid line in FIG. 1B to the inside of the bag body to be the position shown by the broken line in FIG.
When the airbag 8 is deployed, the airbag comes out from the inside of the airbag, so that the airbag airbag 18 for the head hardly interferes with the occupant 16 or the upper portion 22A of the center pillar garnish 22, etc. The deployment of the head airbag 18 can be completed in a shorter time as compared with an airbag which is simply folded and rolled.

４も迅速に展開する。Further, in the chest airbag bag 24, since the bag is folded into the bag, that is, a so-called cactus fold, the bag comes out from the inside of the bag when the bag is deployed. Interference between the airbag bag body 24 and the occupant 16 or the side of the passenger compartment with little interference
4 also develops quickly.

Since the height of the airbag bag is set to 6C, the chest airbag bag 24 enters the gap between the shoulder 16C of the occupant 16 and the side of the passenger compartment within a short time after the start of the deployment of the airbag bag. Since the head airbag 18 is deployed above the chest airbag 24, the deployment of the head airbag 18 is obstructed by the shoulder 16C of the occupant 16 and the side of the passenger compartment. The head airbag bag 18 is easily deployed, and the deployment completion time of the head airbag bag 18 can be further reduced.
