装置を提供することを目的とする。[0004] As a result, there arises a problem that it is difficult to store the airbag device in the storage section. Therefore, in order to cope with such a problem, the present invention folds a substantially square airbag so that the outer peripheral edges of the outer peripheral edges do not overlap in the outer peripheral edge direction. The purpose is to provide.

As a result, the folded thickness of the airbag does not increase due to the sewing or joining. According to the second aspect of the present invention, the opposed outer peripheral edge of the airbag, together with the two obliquely folded portions, has one outer periphery based on a fold line orthogonal to the deployment direction at a middle portion of the airbag in the deployment direction. It is folded as an orthogonal fold towards the edge.

畳み部Ｄ１、Ｄ２として折り畳む。Next, a method of folding the airbag B accommodating the inflator G will be described with reference to FIGS. First, the outer peripheral edges P2 and P3 located on both sides of the outer peripheral edge P1 of the airbag main body 10 are combined with both ends of the outer peripheral edge P4 opposed to the outer peripheral edge P1 on the center side of the upper wall 10a (the airbag main body 10). In the diagonal direction (to the center line Q side of FIG. 3), the two fold lines D1 and D2, which will be described later, are folded based on the fold lines H1 and H2.

心線Ｑに対し傾斜している。In this case, as shown in FIG. 4, the folding line H1 corresponds to a straight line inclined by a predetermined angle θ with respect to the intersection Q1 between the center line Q of the airbag body 10 and the opposing outer peripheral edge P4. On the other hand, the folding line H2 has
A boundary portion P13 between P1 and P3 (a portion near the lower side of the opening 11 in FIG. 4), and a boundary portion P14 between the outer peripheral edges P3 and P4.
And the folding line H2 is inclined with respect to the center line Q.

1 (diagonally folded portion D1) is folded toward the center line Q with reference to the folding line H1, and a portion below the folding line H2 of the airbag body 10 (diagonally folded portion D2). Is folded to the center line Q side with respect to the folding line H2, the respective folding widths of the two oblique folding portions D1 and D2 and the predetermined angle θ are selected so that the oblique folding portions D1 and D2 do not overlap each other. ing.

The folded state is as shown in FIG. In this case, since the two obliquely folded portions D1 and D2 do not overlap each other, the folded thickness of the airbag body 10 is reduced by the upper wall 10.

2 may be appropriately changed on the premise that the two do not overlap each other and that the stitches of the stitch L do not overlap in the stitch direction. Next, the airbag body 10 folded as described above is folded as an orthogonal folded portion D3 toward the lower wall 10b so as to be orthogonal to the center line Q with respect to the folding line R shown in FIG.

当該縫い目が重なる場合に比べて、薄くなる。In this case, as described above, the center line Q is set so that the two obliquely folded portions D1 and D2 do not overlap each other.
It is folded at an angle. For this reason, the portion included in the orthogonally folded portion D3 of the seam L only intersects with each portion included in the diagonally folded portions D1 and D2 of the seam L, and does not overlap in the seam direction. Therefore, the thickness of the airbag body 10 having the two obliquely folded portions D1, D2 and the orthogonally folded portion D3 is smaller than that in the case where the seams in the seam L direction overlap.

り畳む。Accordingly, the seams L included in the two obliquely folded portions D1, D2 and the two orthogonally folded portions D3, D4, D5 do not overlap with each other, and as a result, the folded thickness of the airbag body 10 is reduced by the seam. It can be thinned without being affected by. After repeating the folding in this way,
The airbag body 10 is folded as an obliquely folded portion D7 toward the upper wall 10a with reference to the folding line R3 shown in FIG.

8 corresponds to a straight line connecting a point on the upper side of the center line Q by a predetermined distance in FIG. 8 and a boundary P12 between the outer peripheral edges P1 and P2, and the folding line R3 is It is inclined with respect to. In this case, as described above, the two obliquely folded portions D1 and D2 are folded in a direction inclined with respect to the center line Q, that is, in a direction inclined with respect to the portions along the outer peripheral edges P2 and P3 of the seam L. . In addition, the orthogonal folds D3 to D5 also have the seam L as described above.
Are folded so that they do not overlap in the seam direction.

納部への収納が容易にできる。Therefore, as described above, even if the diagonally folded portion D7 is provided, the seam L does not overlap in the seam direction. For this reason, the final thickness of the folded airbag body 10 is substantially equal to the sum of the folded thicknesses of the unsealed portions of the upper wall 10a and the lower wall 10b. As a result, the folded thickness of the airbag body 10 is suppressed to a minimum, so that the airbag B can be easily stored in the storage section.

Is larger than the folding width of the obliquely folded portion D2, so that when the obliquely folded portion D7 based on the folding line R3 is folded, the thickness near the boundary between the outer peripheral edges P1 and P2 can be reduced. Further, in a state where the airbag B folded as described above is stored in the storage section, when the ignition control device ignites the inflator G in response to the detection of the acceleration sensor for the collision of the vehicle, the inflator G Gas is injected from the inflator body 30 into the airbag body 10 through the opening 11 to deploy the airbag body 10 in the deployment direction (forward of the backrest of the passenger seat). In this case, since the airbag body 10 is sequentially deployed in the direction opposite to the folding direction, the deployment of the airbag body 10 is performed smoothly.
