44 is slidably held. Then, the hinge bar 43 is provided with a hinge portion 45, and the slide sheet 41 is centered on the hinge portion 45.
It can be flipped up and folded, and slidable in the front-back direction of the vehicle body.

In the present embodiment having the above-described structure, the seat rail 32 slidably supporting the slide seat 41 is provided with the bracket 15 which is erected on the wheel house 6 and the front side F of the vehicle body 1 with respect to the bracket 15. Since it can be supported by the first to third angle members 33 to 35 provided at three places, the rear pillar 11 provided and the back pillar 12 provided on the rear side R side of the vehicle body 1 from the bracket 15, The fixing strength of the seat rail 32 can be increased as compared with the conventional case where the seat rail 32 is fixed only to the wheel house 6. Also,
The seat rail 32 has a front end portion, a midway portion, and a rear end portion fixed to the angle members 33 to 35, so that the supporting force of the slide seat 41 supported via the seat rail 32 is It can be kept constant at all movement positions on the seat rail 32. Therefore, the tensile strength of the seat belt provided on the slide seat 41 can be increased in all areas on the seat rail 32.

The bracket 15 to which the angle members 33 to 35 are fixed, the rear pillar 11, and
Since all of the back pillars 12 are provided on the outer panel 9 which is integrated with each other, the angle members 33 to 35 are formed.
It is possible to improve the relative positional accuracy in the. This improves the mounting accuracy of the seat rail 32,
The slidability of the slide sheet 41 can be improved.

On the other hand, the bracket 15 extending between the wheel house 6 and the window lower rail 14 and arranged between the rear pillar 11 and the back pillar 12 is, as shown in FIG. Since the extending surface 25 extends along the outer panel 9, the tension rigidity of the outer panel 9 at the lower portion of the window lower rail 14 can be increased.

The bracket 15 has a first member 21 extending along the outer panel 9 between the wheel house 6 and the window lower rail 14.
And a second portion provided on the lower forming portion 23 of the first member 21.
As shown in FIG. 2, the lower end of the bracket 15 to which the second angle member 34 is fixed is composed of a member 22. The second member 22 bridging into 26, 26 and the wheel house outer 8 form a closed cross-sectional shape. Therefore, the rigidity of the lower end portion of the bracket 15 can be increased, and the seat rail 32 can be improved.
The fixing force can be increased, and the durability when the slide sheet 41 is flipped up and folded can be increased.

Further, at the lower end portion of the bracket 15, the height dimension H of the upright surfaces 26, 26 of the first member 21 is increased, so that the cross-sectional shape of the first member 21 changes rapidly. Is configured. For this reason, the rigidity of the lower end portion of the bracket 15 can be further enhanced, whereby the seat rail 32 is
The fixing force and durability of can be further enhanced.

As described above, in the bracket 15, since the rigidity of only the lower end portion to which the second angle member 34 is fixed is increased, the lower end portion of the bracket 15 and the upper portion extending from the lower end portion. In (1) and (2), it is possible to make a large change in the rigidity force, and to reduce the transmission force of the external force applied to the lower end portion to the upper portion. Therefore, the influence on the outer panel 9 by the external force from the slide seat 41 applied via the seat rail 32, specifically, the outer panel 9
It is possible to minimize distortion and the like.

[0027]

As described above, according to the present invention,
Seat rails that slidably support the slide seat are provided at three positions of a bracket, a first pillar provided on the front side of the vehicle body with respect to the bracket, and a second pillar provided on the rear side of the vehicle body with respect to the bracket. Since the seat rail can be supported by the fixed portion that is set, it is possible to increase the fixing strength of the seat rail as compared with the conventional case in which the seat rail is fixed only to the wheel house. Further, since the front end portion, the middle portion, and the rear end portion of the seat rail are fixed, the supporting force of the slide seat supported via the seat rail is not changed by all movements on the seat rail. It can be kept constant in position. Therefore, the tensile strength of the seat belt provided on the slide seat can be increased in all areas on the seat rail. Further, since all of the bracket having the fixing portion set, the first pillar, and the second pillar are provided on an integral outer panel, relative positional accuracy between the fixing portions is high. Can be increased. As a result, the mounting accuracy of the seat rail is improved, so that the slidability of the slide seat can be improved.

Further, between the first and second pillars,
While forming a window lower rail that forms the lower edge of the window frame portion, the bracket is set to a length dimension that reaches the window lower rail and extends along the outer panel, and the upper end of the bracket is set to the window lower rail. With respect to the one fixed to, the tension rigidity of the outer panel at the lower part of the window lower rail can also be increased by the bracket extending between the window lower rail and the wheel house.

Further, the bracket is a first member having an extending surface extending in the vertical direction along the outer panel, and an upright surface standing inward in the vehicle interior from both ends of the extending surface in the vehicle longitudinal direction. If the second rail member is provided at the lower end of the first member and forms a closed cross-sectional shape together with the first member, and the fixing portion is formed with the second member, the fixing portion of the seat rail is Second set
Since the member forms a closed cross-sectional shape together with the first member, the rigidity and durability of the fixing portion are improved, and thus the fixing force of the seat rail can be increased.

Preferably, the height dimension in the upright direction on the upright surface upright from the extending surface is increased at the lower end portion provided with the second member, whereby the rigidity and durability of the fixed portion are increased. The seat rail is further enhanced, and accordingly, the fixing force of the seat rail can be further enhanced.

As described above, in the bracket,
Since the rigidity of only the lower end portion in which the fixing portion is set is increased, it is possible to make a great change in the rigidity force at the lower end portion of the bracket and the upper portion extending above the lower end portion, The transmission force of the external force applied to the lower end to the upper part can be reduced. Therefore, the influence on the outer panel by the external force from the slide seat applied via the seat rail, specifically,
It is possible to minimize distortion and the like of the outer panel.
