  By the way, due to diversification of vehicle designs in recent years, the A pillar 104 on the front end side and the A pillar on the vehicle front side of the opening (side window) 101 as in the vehicle V shown in FIGS. A large triangular window 109 may be formed by the sub-pillar 105 on the rear side of 104, and it is considered that such a vehicle is provided with the curtain airbag device 110 as described above. FIG. 6 is a front view of the curtain airbag device (occupant protection device) constituting the interior structure of the vehicle as viewed from the vehicle interior side in the accommodated state of the curtain member, and FIG. 7 is the curtain airbag shown in FIG. It is the front view which looked at the bag apparatus from the vehicle interior side in the expansion | deployment state of a curtain member. In the figure, the arrow (F) indicates the front of the vehicle, and the arrow (R) indicates the rear of the vehicle.

  In the vehicle V shown in FIGS. 6 and 7, the triangular window 109 becomes so large that it extends to near the height position of the head of the occupant C of the seats S <b> 1 to S <b> 3, and thus the pillars 104 and 105 are long. It has become a rule.

  Here, the pillar is generally covered with a pillar trim from the vehicle interior side. In the pillars 104 and 105, the pillar trim 123 is provided on each pillar 104 and 105 as shown in FIG. Corresponding portions 123a and 123b are integrally formed.

  For this reason, in the structure shown in FIG. 8, the pillar trim 123 is increased in size, including the necessity to correspond to the elongated pillars 104 and 105 as the triangular window 109 increases. FIG. 8 is a perspective view of the area around the A pillar and the sub pillar shown in FIG. In the figure, the arrow (IN) indicates the inside of the vehicle, and the arrow (OUT) indicates the outside of the vehicle.

  Here, let us consider a case in which the above-described curtain airbag device is provided for such a configuration. In this case, as shown in FIG. 6 to FIG. 8, the tether 113 as the connecting portion is not caught by the pillar trim 123 formed integrally with the end of the curtain member 111 when the curtain member 111 is deployed. It is preferable to fix to the sub pillar 105 instead of the A pillar 104.

  Furthermore, in order to more reliably protect the head of the occupant C, generally, as shown in FIG. 7, the line of the tether 113 when the curtain member 111 is deployed is as close to the belt line as possible below. It is preferable to take the position. For this reason, it is ideal that one end portion of the tether 113 is attached in the vicinity of the lower end portion of the sub pillar 105 as shown in the figure.

  However, when the attachment position of the sub pillar 105 of the tether 113 is set in the vicinity of the lower end portion thereof, particularly when the lower end portion of the pillar trim 123 is fixed by a fixing member positioned below the pillar, the tether 113 is developed with the deployment of the curtain member 111. So that the portion 123b of the pillar trim 123 falls out of the sub pillar 105, and the upper end of the portion 123b falls into the vehicle interior side in the vehicle width direction with the lower end as a fulcrum. May occur.

  When such an inward fall phenomenon occurs, the portion 123a side that is not easily affected by the deployment of the curtain member 111, that is, the movement of the tether 113, is held in the fixed state by the A pillar 104. , 123b and a large load is applied to the pillar trim 123 to cause cracks and breakage.

  Further, when the curtain member 111 is inflated and deployed, the portion 123b of the pillar trim 123 is detached from the sub pillar 105, so that the end of the tether 113 on the curtain member 111 side is an opening portion between the sub pillar 105 and the portion 123b on the rear side of the vehicle. In this case, if the portion 123b is not sufficiently separated from the sub-pillar 105, the movement of the tether 113 is hindered, and the curtain member 111 cannot be appropriately tensioned. End up.

  The present invention provides an interior structure of a vehicle capable of reducing stress applied to a pillar trim while allowing tension to be applied in the vehicle front-rear direction at a relatively lower side of the curtain member when the curtain member is deployed. The purpose is to provide.

  Further, according to the present invention, when the curtain member is deployed, the pillar trim corresponding to the second pillar can be appropriately moved, and the pillar trim is sufficiently separated from the second pillar so that the connecting portion is shifted to a state of extending in the vehicle front-rear direction. An object of the present invention is to provide an interior structure of a vehicle that can perform the above.
