Further, as shown in FIG. 3, the cut-and-raised portion 17 is provided at a position different from the bolt 18 for attaching the airbag module 6 to the side frame 10. The cut-and-raised part 17 is provided in front of the sheet S with respect to the bolt 18 and is disposed at a distance in the front-rear direction of the sheet S.

The modification of the raising part of this invention is shown in FIGS.
The cut-and-raised portion 17 ′ in this example is provided substantially parallel to the front edge portion 12 ′ at a position close to the front edge portion 12 ′, and is erected from the side plate 11 ′ toward the inside of the sheet S. As shown in FIG. 9, the cut-and-raised portion 17 ′ is formed in a T shape in which the tip end portion 17 ′ b is longer than the base portion 17 ′ a in the extending direction of the front edge portion 12 ′. The corners of all end portions of the tip portion 17'b are rounded to facilitate insertion of the tip portion 17'b into the locking groove 67 '.

Moreover, the lower end surface of the part which is not continuing to root part 17'a of front-end | tip part 17'b becomes a slope inclined so that the center root part 17'a side may become low. Thus, the lower end surface of the portion that is not continuous with the root portion 17′a of the tip portion 17′b is an inclined surface that is inclined so that the root portion 17′a side is lowered, thereby the tip portion 17 ′. b can be easily inserted into the locking groove 67 '.
A mounting member 50 ′ shown in FIGS. 9 to 12 is attached to the side frame 10 ′ provided with the cut and raised portion 17 ′ of this example. The second extending portion 65 ′ of the attachment member 50 ′ is provided with a locking groove 67 ′ that engages with the cut and raised portion 17 ′.

The locking groove 67 ′ has an opening 67′a provided in the outer wall surface 65′o of the second extension portion 65 ′, and is perpendicular to the outer wall surface 64′o of the first extension portion 64 ′. The three extending portions 66 'are formed as grooves parallel to the outer wall surface 66'o. The locking groove 67 ′ extends between both ends in the extending direction of the mounting member 50 ′, that is, from the upper end to the lower end.
The third extending portion 66 ′ has an outer wall surface 66′o extending in the direction opposite to the end portion 66′e of the third extending portion 66 ′, and this extended portion corresponds to the locking groove 67 ′. A side wall 67'b on the opposite side of the extending portion 64 'is formed.

The side wall 67'b of the locking groove 67 'is cut out in a substantially rectangular shape near the center in the extending direction of the mounting member 50' to form an opening 67'c. The length of the opening 67′c in the extending direction of the attachment member 50 ′ is formed larger than the width in the extending direction of the root portion 17′a of the cut and raised portion 17 ′.
The side wall 67'b is divided into two by the opening 67'c, and the region extending from the third extending portion 66 'to the side wall 67'b has a U-shape.

On the side wall 67'd facing the side wall 67'b, a convex portion 67'e extending in the extending direction of the attachment member 50 'is formed along the length direction of the opening 67'a. The convex portion 67′e has a surface on the back side of the locking groove standing vertically from the side wall 67′d, but may be formed at an obtuse angle with respect to the side wall 67′d. As shown in FIG. 11, the convex portion 67′e is formed only at a location facing the side wall 67′b, and is not formed at a location facing the opening 67′c.
The attachment member 50 ′ is attached to the front edge portion 12 ′ when the lower end of the tip portion 17′b of the cut and raised portion 17 ′ is locked to the convex portion 67′e.

The attachment member 50 'is attached as follows. First, the trim plate 37 to which the end of the force cloth 32 is attached is locked to the locking portion 55 ′ of the mounting member 50 ′.
In this state, the groove 53 ′ is locked to the front edge portion 12 ′. The locking groove 67 ′ of the mounting member 50 ′ is abutted against the upper or lower end portion of the sheet S of the leading end portion 17 ′ b, and the mounting member 50 ′ is slid along the front edge portion 12 ′. Insert 'b into the locking groove 67'.
When only the tip portion 17'b advances in the locking groove 67 'and the root portion 17'a is outside the locking groove 67', the tip portion 17'b and the convex portion 67'e abut each other. In other words, the side surface of the distal end portion 17'b and the side walls 67'b, 67'd are in a substantially parallel state.

When the root portion 17'a is inserted into the locking groove 67 ', the curved outer surface of the root portion 17'a abuts against the convex portion 67'e.
There is a slight gap between the locking groove 67 'and the tip 17'b. Accordingly, as shown in FIG. 12, the end portion of the side wall 67'b is brought into contact with the curved inner surface of the root portion 17'a, and the tip of the convex portion 67'e is brought into contact with the curved outer side of the root portion 17'a. When the mounting member 50 ′ is brought into contact with the surface and inclined so that the first extending portion 64 ′ side is slightly separated from the side plate 11 ′, the root portion 17 ′ is formed with the locking groove 67 ′ and the tip portion 17 ′. b can be inserted.
Thus, by providing a gap between the locking groove 67 ′ and the tip portion 17′b, the tolerance between the locking groove 67 ′ and the tip portion 17′b can be absorbed.
In addition, it is not necessary to provide a gap between the locking groove 67 ′ and the tip portion 17′b. In the case where no gap is provided between the locking groove 67 ′ and the distal end portion 17′b, it is possible to prevent the cut and raised portion 17 ′ from rotating in the locking groove 67 ′.

In FIG. 12, the tip portion 17 ′ b inserted first reaches the opening 67 ′ c, the root portion 17 ′ a reaches between the side wall 67 ′ b and the convex portion 67 ′ e, and the other tip portion 17 In the state where ′ b remains outside the locking groove 67 ′, the vicinity of the locking groove 67 ′ of the cut and raised portion 17 ′ and the mounting member 50 ′ is extended in the extending direction of the mounting member 50 ′ at the opening 67 ′ a. It is sectional explanatory drawing at the time of cut | disconnecting on a perpendicular surface.
At this time, the side surface of the tip end portion 17'b and the side walls 67'b, 67'd are in an inclined state.

When the root portion 17'a passes between the convex portion 67'e and the side wall 67'b, it is accommodated in a range facing the opening 67'c as shown in FIGS. Here, since there is no convex portion 67′e and does not become an obstacle, the attachment member 50 ′ returns to the state in which the side surface of the tip portion 17′b and the side walls 67′b and 67′d are substantially parallel again. .
The tip portion 17'b engages with the convex portion 67'e and is stored in the locking groove 67 '. Accordingly, when the trim plate 37 locked to the locking portion 55 ′ receives a tensile force from the force cloth 32, the attachment member 50 ′ is moved to the end portion 12 ′ of the front edge portion 12 ′ of the side frame 10 ′. Rotation in the outer surface side of the front edge portion 12 ′, in other words, on the extended portion 54 ′ side, that is, in the direction of arrow E in FIG.

Further, the tip portion 17'b has a convex portion 67'e and a side wall unless the attachment member 50 'is inclined in the direction in which the first extension portion 64' side is separated from the side plate 11 'about the tip of the side wall 67'b. 67′b cannot pass through and cannot move in the vertical direction of the mounting member 50 ′. This direction is the direction opposite to the direction in which the attachment member 50 ′ tries to rotate when receiving the tensile force from the webbing 32, and is difficult to rotate while using the sheet S of the present embodiment. . Accordingly, during use of the sheet S, the leading end portion 17'b is difficult to move in the vertical direction of the mounting member 50 ', and the vertical position restriction of the mounting member 50' is achieved by the cut and raised portion 17 '. The
Furthermore, since the opening 67′c that accommodates the base portion 17′a of the cut and raised portion 17 ′ is provided at the center in the vertical direction of the mounting member 50 ′, the vertical position regulation of the mounting member 50 ′ is achieved.
Further, since the cut-and-raised portion 17 'is configured in a substantially T shape, the engagement length between the tip portion 17'b and the convex portion 67'e is increased while the cut-and-raised portion 17' is made compact. This makes it possible to improve the support rigidity by the cut and raised portion 17 '.
The locking groove 67 ′ is formed in the second extending portion 65 ′ that is formed to be the thickest among the surfaces where the mounting member 50 ′ contacts the side plate 11 ′. Support rigidity of the raising portion 17 ′ can be ensured.

In the present embodiment, the rotation of the attachment member 50 is suppressed by the cut-and-raised portion and the recess or the locking groove, but the present invention is not limited to this, and other examples of the rotation suppression member are as shown in FIGS. In addition, the erection member 26 may be used.
As shown in FIGS. 13 and 14, the attachment member 50 is disposed above the locking portion 16.
