  The slide door 9 is driven to open and close by a drive mechanism. The drive mechanism includes a drive unit 15b including a drive motor, an endless cable 15c coupled to the drive unit 15b and the door support member 27, and a pair of front and rear guide pulleys 15d for guiding the cable 15c, 15e.

  The cable 15c is disposed along the rail body 15a, and is disposed so as to pass through the drive unit 15b and the guide pulleys 15d and 15e. The slide door 9 is driven forward by rotating the motor in the drive unit 15b forward, for example, and the slide door 9 is driven rearward by rotating the motor reversely, for example.

  Here, in this embodiment, as shown in FIGS. 6, 9, and 10, the front end portion of the rail portion 15 (guide pulley 15d) is located on the vehicle exterior side of the fixing portion 19a of the side trim 19 in front of the retractor 20b. It extends from the end to the inside of the car. And about the positional relationship with webbing 20a, the site | part by the side of the retractor 20b is arrange | positioned so that it may pass diagonally between the front-end part of the rail part 15, and the fixing | fixed part 19a toward the upper direction from the retractor 20b. Yes.

  For this reason, even in the automobile 1 provided with the entrance 8 and the rail portion 15 as in the present embodiment, while sufficiently securing the pull-in width L1 (see FIG. 10) of the slide door 9 in the rail portion 15, The retractor 20b can be arranged behind the entrance 8 in a compact manner. Further, since the webbing 20a obliquely passes between the front portion of the rail portion 15 and the fixed portion 19a, the gap in the front-rear direction between the portions 20a, 15 and 19a can be reduced. Therefore, the winding portion 25a of the tonneau cover 25 Can be arranged more forward.

  Further, the seat belt device 20 and the tonneau cover 25 can be arranged in a compact manner so that the entrance / exit 8 can be rearward without sacrificing the safety due to the installation of the seat belt device 20 or the storage of the luggage X due to the front arrangement of the tonneau cover 25. Can be expanded. Therefore, as described above, when the walk-in mechanism including the slide rail 16 and the reclining mechanism 17 is provided, it is possible to easily get on and off the third row seat 5 in particular.

  Further, in the relationship between the rail portion 15 and the seat belt device 20, the front end portion 15a1 of the rail body 15a is curved inward of the vehicle, so that the front end portion of the rail portion 15 is more forward than the portion of the webbing 20a on the retractor 20b side. And it extends to the inside of the car. Thereby, the front end part of the rail part 15 and the seatbelt apparatus 20 are arrange | positioned compactly, and the drawing-in width | variety L1 of the slide door 9 of the rail part 15 can be ensured large. And the part by the side of the retractor 20b of the webbing 20a turned in the vehicle width direction and the front-end part of the rail part 15 can be piled up in the vehicle width direction, and can be arrange | positioned compactly.

  Thus, the configuration for ensuring a large pull-in width of the rail portion 15 is, for example, in recent years, with the strength of the steel plate itself used for the outer panel 12 and the inner panel 26 used for the vehicle body panel being improved. It is preferable when the side wall of the vehicle body is formed thin in the vehicle width direction to ensure the width of the passenger compartment R1.

  In this case, since the line of the side trim 19 on the side wall of the vehicle body is shifted to the outside of the vehicle, when the above-described slide door 9 is provided, the position where the front end portion of the rail portion 15 enters the vehicle compartment R1 side relatively. However, in this embodiment, since the front end portion of the rail portion 15 is disposed so as to extend to the vehicle inner side than the webbing 20a, it is possible to easily secure the width of the passenger compartment R1. it can.

  Moreover, the structure which ensures the pull-in width | variety of the rail part 15 has the bulging part 12a which has thickness in the outer panel 12 of a vehicle body, aiming at the design improvement of a vehicle body outer surface like this embodiment. Is preferred.

  FIG. 11 is a comparison diagram for explaining the difference in the pull-in widths of the rail portions 15 and 115 when the bulging portion 12a is formed on the outer panel 12 and when it is not. In this embodiment, as shown in FIG. 11 (a), the sliding door 9 is placed more on the outside of the vehicle than in the case of FIG. 11 (b) so that it does not interfere with the projection 12a when the sliding door 9 is opened. Need to be displaced.

  And in order to displace the slide door 9 to the vehicle outer side in this way, the pull-in width L1 to the vehicle inner side of the rail portion 15 when the slide door 9 is closed is set to the rail portion 115 of FIG. It is necessary to ensure a larger value than the pull-in width L2. In this case, the front end 15a1 of the rail body 15a is necessarily positioned on the vehicle inner side than the front end 115a1 of the rail main body 115, and the guide pulley 15d is disposed on the vehicle inner side than the guide pulley 115d of 115.

  In the present embodiment, the front end portion 15 of the rail portion 15 is disposed so as to extend to the vehicle inner side than the webbing 20 a, thereby preventing interference between the slide door 9 and the outer panel 12, and the thickness of the outer panel 12 of the automobile 1. It is possible to give a certain design.

  As shown in FIGS. 2 and 3, in this embodiment, a wheel house 21 is provided below the second row seat 4 and near the lower side of the retractor 20 b. In this case, although the space for disposing the seat belt device 20 and the rail portion 15 is limited due to the presence of the wheel house 21, the front end portion of the rail portion 15 is located above the lower end of the retractor 20b and ahead of the webbing 20a. By disposing, the seat belt device 20 and the rail portion 15 having a large pull-in width L1 can be compactly disposed above the wheel house 21.

  Further, by arranging the seat belt device 20, the fixing portion 19 a of the tonneau cover 25, and the rail portion 15 in a compact manner in the front-rear direction, these can be concentrated further forward than the third row seat 5. For this reason, while ensuring the space which puts an elbow on the level | step-difference part 19b mentioned above in the vicinity of the 3rd row sheet | seat 5 of the side trim 19, the cup holder 19c mentioned above (refer FIG.2, FIG.3 etc.) in the front. The food and drink can be held at a position that can be easily reached by the passenger seated on the third row seat 5.

  Further, as shown in FIGS. 9 and 10, the front end portion of the rail portion 15 is disposed so as to overlap in the front-rear direction on the vehicle outer side of the tip side portion of the webbing 20 a. Thereby, the front end side part of the webbing 20a and the front end part can be arranged more compactly in the front-rear direction.

  Further, the driving portion 15b of the rail portion 15 is provided behind the webbing 20a, and the cable 15c is disposed so as to bypass the webbing 20a from the guide pulley 15d toward the rear side of the vehicle exterior. Thereby, the drive part 15b which opens and closes the sliding door 9 is provided, and the seat belt device 20 and the rail part 15 can be compactly arranged in the vehicle width direction while improving convenience when getting on and off.

  FIG. 12 is a perspective view of the second row seat 4 as seen from the vehicle exterior side. As shown in FIGS. 9 and 10, in the seat back 4 b of the second-row seat 4, the cover member 30 that closes the recess formed by the rear outside portion of the seat back 4 b and the armrest 4 d in the retracted position is provided. Installed.

  The cover member 30 is a substantially rectangular member having elasticity made of, for example, a rubber material, and is arranged so that its longitudinal direction is along the longitudinal direction of the armrest 4d at the retracted position. The length in the longitudinal direction is substantially the same as the length in the longitudinal direction of the armrest 4d.

  In addition, when the armrest 4d is in the retracted position when the armrest 4d is not in use, the cover member 30 abuts against the rear surface of the armrest 4d and presses the front end of the outside of the vehicle toward the outside and the rear. 10, the vehicle is displaced forward as indicated by a two-dot chain line in FIG. 12 and is substantially along the vehicle outer side surface of the seat back 4b.

  In the present embodiment, in order to ensure the comfort of the passenger compartment R1, as shown in FIG. 7, FIG. 9, and FIG. 10, the seat width of the second row seat 4 is extended to the position where the tip side portion of the webbing 20a is applied to the armrest 4d. Is widened to the outside of the car.

  With such a configuration, when the webbing 20a is pulled forward, it is passed between the seat back 4b and the side trim 19 and between the armrest 4d and the side trim 19. At this time, even if the armrest 4d is in the retracted position, it is ensured that the cover member 30 closes the recess, so that the webbing 20a enters the recess and is sandwiched between the seat back 4b and the armrest 4d. Can be prevented.

  In order to prevent such intrusion of the webbing 20a, for example, an armrest may be provided on the slide door 9 side. However, in such a case, it is necessary to ensure a large displacement width to the outside of the vehicle when the slide door 9 is opened, and it is necessary to set the pull-in width of the rail portion 15 when the slide door 9 is closed.

  By the way, as a member for guiding the webbing 20a when the webbing 20a is pulled out forward, for example, there is one disclosed in Japanese Patent Publication No. 9-512224. In this document, the armrest is provided with a guide portion for guiding the webbing along the longitudinal direction thereof, and when the armrest is moved to the use position, the webbing is simultaneously pulled out along the guide portion. Yes.

  However, in this conventional structure, when the occupant can get on and off the third row seat 5 at the entrance 8 as in the present embodiment, the webbing is pulled forward when the armrest is in the use position. Since this crosses the passage (entrance / exit) for getting on and off the third row seat, there is a problem that this webbing becomes an obstacle at the time of getting on and off.

  On the other hand, the cover member 30 of the present embodiment merely has a role of closing the concave portion, and does not actively move in the pulling-out direction of the webbing 20a. That is, when the walk-in mechanism as described above is provided, the webbing 20a can be guided by the cover member 30 so as not to obstruct getting on and off the third row seat 5.

  In addition, in embodiment shown in FIGS. 1-12, although the front-end part of the rail part 15 was arrange | positioned in the position which overlaps with the front end side site | part of the webbing 20a in the front-back direction, it is not necessarily limited to this. . For example, as shown in FIG. 13, when the position of the second-row seat 4 is set in front of the first embodiment shown in FIGS. 1 to 12, the tip side portion of the webbing 20 a is positioned forward, Like the rail portion 15 ′, the front end portion (guide pulley 15 d ′) may be disposed between the retractor 20 b side portion and the distal end side portion of the webbing 20 a in the front-rear direction.

  As a result, the front end portion 15a1 'of the rail body 15a' is further arranged on the vehicle interior side as shown in the figure without having to largely detour around the retractor 20b side portion and the tip side portion of the webbing 20a, and the guide pulley 15d ′ Can be disposed further on the vehicle inner side than the portion on the retractor 20b side and the tip side portion of the webbing 20a. Thereby, the pull-in width of the rail portion 15 'can be further ensured.

  Further, in this case, the seat belt device 20 and the rail portion 15 can be arranged in a compact manner by arranging the guide pulley 15d ′ so as to overlap the retractor 20b side portion and the tip side portion of the webbing 20a in the vehicle width direction. .

  Furthermore, when the webbing 20a is pulled out to the inside of the vehicle, the tip side portion is separated forward from the front end portion of the rail portion 15 ', so that interference between the two can be reliably prevented.
