In this way, the rear tether 25B is disposed obliquely from the vehicle front inner side to the vehicle rear outer side in a plan view, so that a part of the longitudinal side of the rear tether 25B is arranged along the boundary region. Even if it is searched, the length of the rear tether 25B can be shortened.

  As described above, when the rear tether 25B is disposed between the first vertical wall 33b1 and the second vertical wall 35a, the rear tether 25B is disposed along the upper portion of the boundary region. In addition, the movement of the rear tether 25B in the direction orthogonal to the longitudinal direction of the rear tether 25B is restricted by the first vertical wall 33b1 and the second vertical wall 35a, and the almost positioned state is maintained. As in the present embodiment, the first vertical wall 33b1 and the second vertical wall 35a are provided along the boundary region, so that the routing state of the rear tether 25B can be easily specified.

  The operation of the interior structure of the vehicle provided with the curtain airbag device 2 will be described in detail below.

  The curtain airbag device 2 is normally stored in a space between a member constituting an exterior such as a roof panel and various pillars and a member constituting an interior such as a roof trim 34 and various pillar trims.

  9 (a) and 9 (b) are diagrams for explaining how the rear tether 25B falls from above the trim using the cross section at the position IX-IX in FIG. FIG. 9A shows a state where the rear tether 25B is routed along the boundary region, and FIG. 9B shows a state where the rear tether 25B falls through the gap.

  In a normal state, in a state where the airbag 24 is folded and stored above the roof trim 34, as shown in FIG. 9A, a part of the longitudinal side of the rear tether 25B is the first vertical wall 33b1. And the second vertical wall 35a, and is placed on the boundary region where the rear edge 35b of the roof side trim 35 and the upper edge 33b2 of the rear rear pillar trim 33b overlap each other vertically. ing.

  When a side collision or rollover of the vehicle occurs, most of the airbag 24 and the tether 25 in the curtain airbag device 2 jump out instantly toward the vehicle interior.

  First, when a predetermined gas pressure is supplied from the inflator 21, as shown in FIG. 5, the airbag 24 is inflated, and the inflation of the airbag 24 presses the upper surface of the side edge 34 a of the roof trim 34. The Then, the side edge 34 a is deformed so as to warp toward the vehicle interior side by the pressing of the airbag 24, and is detached from the upper surface of the long side edge 35 c of the roof side trim 35. By deforming the side edge 34 a of the roof trim 34, a gap for the airbag 24 to bulge is secured between the long side edge 35 c of the roof side trim 35 and the side edge 34 a of the roof trim 34. The The airbag 24 bulges into the vehicle interior through this gap. In the present embodiment, the rear end side of the airbag 24 is formed not by a space between the rear rear pillar trim 33b and the rear rear pillar formed by a hard material but by a material more flexible than the rear rear pillar trim 33b. Since it is stored above the roof trim 34, when the airbag 24 is inflated, the side edge 34 a of the roof trim 34 is easily deformed greatly, and a sufficient clearance is secured for the airbag 24 to inflate smoothly. it can. Moreover, since the bent portion 24a is disposed on the inner side in the vehicle width direction with respect to the roof side trim 35, the bent portion 24a is prevented from interfering with the roof side trim 35 when the bent portion 24a expands. be able to.

  When the airbag 24 is inflated, the second fixing portion 25B2 fixed to the airbag 24 is pulled downward along with the inflation of the airbag 24. In response to this pulling force, the portion placed on the boundary region of the rear tether 25B presses the boundary region downward. As shown in FIG. 9B, the rear edge portion 35b of the roof side trim 35 and the upper edge portion 33b2 of the rear rear pillar trim 33b receive a pressing force from the rear tether 25B and are directed toward the vehicle interior side. That is, it deforms downward. Due to the deformation of the rear edge portion 35b of the roof side trim 35 and the upper edge portion 33b2 of the rear rear pillar trim 33b, there is a clearance in the longitudinal direction of the rear tether 25B so that the rear tether 25B can fall into the vehicle interior. Secured along. The rear tether 25B passes through this gap and falls into the vehicle interior, and as shown by a two-dot chain line in FIG. 6, the rear rear pillar trim 33b is slightly deformed to form the side window glass 5 and the rear rear pillar trim. A clearance enough to allow the rear tether 25B to pass through is secured between the rear rear pillar trim 33b and the rear rear pillar 43. In particular, in the present embodiment, the first vertical wall 33b1 restricts the rear tether 25B from moving inward in the vehicle width direction with the longitudinal direction being along the vehicle longitudinal direction. It is derived in a state of wrapping around the window glass 5 side.

  According to the above embodiment, the airbag 24 has the bent portion 24a in which the rear end is bent toward the front end in the state where the airbag 24 is stored above the roof trim 34. Is formed. That is, it is not necessary to secure a gap for inflating a part of the airbag 24 by deforming the rear rear pillar trim 33b made of hard synthetic resin, and the roof trim 34 made of a material more flexible than the rear pillar trim 33b is deformed. By doing so, a sufficient gap is secured and the airbag 24 is inflated. Therefore, the airbag 24 can be smoothly deployed. Further, the rear tether 25B has a part of the longitudinal side of the rear tether 25b and the rear edge 35b of the roof side trim 35 in a state where the airbag 24 is stored above the roof trim 34. It is routed along the area. When the airbag 24 is deployed, the rear tether 25B is pulled by the airbag 24 in the direction of pressing the boundary area simultaneously with the inflation of the airbag 24, and the rear edge of the rear pillar trim 33b and the roof side trim 35 are rearward. The boundary area with the edge 35b is deformed. By this deformation, a gap is secured between the rear rear pillar trim 33b and the roof side trim 35, and the rear tether 25B falls through the gap to the vehicle interior side. Therefore, even if the roof side trim 35 is provided, the rear tether 25B can be easily led out and the deployability of the airbag 24 can be improved.

  In the above embodiment, the first vertical wall 33b1 and the second vertical wall 35a are provided, and the rear tether 25B is routed along the boundary between the roof side trim 35 and the rear rear pillar trim 33b. However, the present invention is not limited to this.
