Abstract

PROBLEM TO BE SOLVED: To cause an air bag provided inside a seat back to deploy diagonally forward to ensure that the air bag enters between an occupant and the inner surface of the side of the vehicle body. SOLUTION: An air bag 6 formed by sewing two ground fabrics 36, 37 together at a sewing part 38 is secured to the holder 31 of an inflator 32 at its rear main parts 361 , 371 and is stored inside a module case 35 while being folded into the shape of bellows at its front folding parts 362 , 372 . The main part 371 of the left ground fabric 37 which is farther away from the center pillar and front door of the vehicle has extra parts between its (b) point and (c) point, and when the folding parts 362 , 372 of the air bag 6 are inflated, the folding parts 362 , 372 can be moved toward the inner surface of the side of the vehicle body because of the extra parts (b)-(c), so that the air bag 6 can be surely advanced between the center pillar or front door and an occupant by being deployed diagonally forward.

In order to achieve the above object, according to the first aspect of the present invention, an inflator generates an airbag which is stored in a folded state inside a seat back of a seat on which an occupant sits. In an occupant protection device that is inflated with gas and deployed between an occupant and an inner surface of a vehicle body side portion, the airbag is configured such that a rear base portion is fixed to a fixing member and a front fold portion is folded forward and backward. And
A surplus portion is provided on a side of the base portion far from the inner surface of the vehicle body side portion to allow the folding portion to move toward the inner surface of the vehicle body side portion.

Between from point to point b as excess portion b-c, are arranged along the excess portion b-c to the right side surface of the main body portion 31 1 of the holder 31. Therefore, when the airbag 6 is inflated, the surplus portions b to c of the base cloth 37 on the inner side in the left-right direction are b
By rotating the airbag 6 counterclockwise around the point, the airbag 6 can freely move to the right (outward in the left-right direction), and can be directed diagonally right without interfering with the occupant's right flank or right arm. And can be deployed smoothly.

As is apparent from FIG. 9, when the airbag 6 is deployed by breaking the sewn portion 25 of the seat back 2, first, as shown in FIG. As shown in (1), it is deployed forward, and finally reaches the fully deployed state shown in (c). As described above, by performing the vertical deployment in preference to the front-back deployment, the side surface of the occupant can be quickly covered over a wide range in the vertical direction, and the occupant can be reliably restrained. . In order to realize this, first, when the airbag 6 is folded, the airbag 6 is folded in the front-rear direction (FIGS. 5B and 6).
(See FIG. 7C), and then folding is performed in the vertical direction (see FIG. 7E). As a result, the airbag 6 is first deployed in the up-down direction, and then deployed in the front-rear direction, and can be deployed in the order described above.
