It can be slid to the rearmost end movement position without causing interference with the 13 portions.

In addition, when the seat 2B in the second row of this embodiment is not in use, the seat back 9 is folded in half on the seat cushion 8, and the entire seat 2B is flipped forward in the state at the foremost end moving position. A so-called tumble operation is possible.
FIG. 7 is a diagram showing a main configuration for realizing the tumble operation of the second row of sheets 2B, and FIG. 8 shows the tumble operation of the sheet 2B sequentially in time series from (A) to (E). FIG.

  As shown in FIG. 7, in the seat 2 </ b> B, a plate-like slide base 24 is slidably supported on a seat rail 23 (lower rail) laid on the vehicle body floor 20, and a rotating hinge 25 is mounted on a front end portion of the slide base 24. The front end portion of the seat cushion 8 is connected to be able to turn back and forth. A seat back 9 is rotatably connected to the rear end portion of the seat cushion 8 via a reclining mechanism 26. Further, a tumble striker 27 made of a substantially U-shaped bar-like member protrudes from the rear end portion of the slide base 24, and a lock mechanism 28 provided at the lower end of the rear portion of the seat back 9 engages with the tumble striker 27. It is like that.

The reclining mechanism 26 is released by operating either a reclining release lever 33 provided at the side of the seat cushion 8 or a reclining release strap 34 provided at the rear end of the standing wall 11 below the armrest 12. It is like that.
In addition, when the reclining mechanism 26 is released, the seat back 9 rotates about the rotation shaft 26a of the reclining mechanism 26 and transitions to a two-stage forward tilted state. That is, the seat back 9 is in a half-tilt state in which it is tilted forward about half before the tumble operation is completed, and then in a full-tilt state in which the seat back 9 is tilted until it overlaps with the seat cushion 8. A semi-falling stopper 31 is provided at the rear end portion of the seat cushion 8, and when the reclining mechanism 26 is released, the stopper pin 32 on the seat back 9 side comes into contact with the half-falling stopper 31. The seat back 9 is maintained in a half-turned state. A slide lock mechanism 35 that locks the slide position of the slide base 24 is provided between the slide base 24 and the seat rail 23. When the seat 2B is not operated at all, the slide lock mechanism 35 maintains the slide base 24 in the locked state.

  As described above, the slide lock mechanism 35 is unlocked in response to the operation of the seat back 9 when the seat back 9 is in a half-tilt state by the release operation of the reclining mechanism 26. When the seat cushion 8 (slide base 24) is slid to the foremost end movement position after the slide lock mechanism 35 is released, the half-falling stopper 31 is then unlocked at the rear end of the seat cushion 8. When 36 is pulled, it is displaced away from the stopper pin 32. As a result, the seatback 9 is released from the rotation restriction by the half-falling stopper 31 and transitions to the full-falling state.

  The locking mechanism 28 that locks the rotation of the front side of the seat cushion 8 is engaged with the tumble striker 27 on the slide base 24 in the normal state, but the seat cushion 8 (slide base 24) is the most. When the seat back 9 moves to the front end movement position and transitions to the all-falling state, the engagement with the tumble striker 27 is released in response to the operation.

Here, a specific tumble operation of the seat 2B will be described with reference to FIGS.
First, when the seat 2B is in the normal posture (the posture in which the seat back 9 stands up rearward), either the reclining release lever 33 or the reclining release strap 34 is operated as shown in FIG. Then, the seat back 9 is tilted forward about the rotating shaft 26a of the reclining mechanism 26 and is in a semi-falling state. Thus, when the seat back 9 is in a half-turned state, the lock of the slide lock mechanism 35 is released.

Next, when the occupant m pushes the seat 2B forward from this state, the seat 2B slides and moves obliquely forward along the seat rail 23 as shown in FIG. 8B. When the seat 2B moves to the foremost end movement position in this manner, the seat back 9 can be shifted to the fully-falling state due to the lock release strap 36 being pulled.
From this state, as shown in FIG. 8C, when the unlocking strap 36 is pulled, the seat back 9 is fully tilted about the rotating shaft 26a of the reclining mechanism 26, and the locking mechanism 28 and the tumble striker 27 are The engagement is released.

  When the engagement of the lock mechanism 28 and the tumble striker 27 is released in this way, the entire seat 2B is rotated as shown in FIG. 8D by the force of a biasing spring (not shown) built in the rotation hinge 25. Slowly rotates (tumbles) around the hinge 25. Thereafter, the seat 2B is locked and fixed to the skeleton member of the vehicle body by the locking tool 37, as shown in FIG.

  In addition, the seat 2C in the third row in the passenger compartment shown in FIG. 1 is pivoted to the seat cushion 108 that supports the buttocks of the occupant m and the rear end portion of the seat cushion 108, like the seat 2B in the second row. A seat back 109 that is connected to support the waist and chest (back) of the occupant m, and a headrest 110 that is attached to the upper part of the seat back 109 and supports the head and neck of the occupant m. ing. The seats 2C in the third row are stored in recesses (not shown) provided on the vehicle body floor 20 at the rear of the vehicle interior, and project from the recesses onto the vehicle body floor 20 during use. In the seat 2C, the seat back 109 is folded in half on the upper surface side of the seat cushion 108 and is stored in the recess in this state, so that the back of the seat back 109 closes the opening of the recess.

The midway part of the webbing 17 whose side is wound up by the retractor 15 can be held along the guide surface 39 of the base part 38.
Therefore, when the interior structure of this embodiment is adopted, the intermediate portion of the webbing 17 is held at a certain position on the side of the vehicle body when the seat belt device 14 is not used without adding separate parts such as a D-ring. Therefore, the manufacturing cost of the vehicle can be reduced.

  In the case of the interior structure of this embodiment, the front end portion of the guide surface 39 that locks the webbing 17 is disposed at a position that substantially coincides with the upper end position of the side portion of the seat back 9 of the seat 2B that is in the last retracted position. Therefore, the webbing 17 on which the seated occupant m is locked to the guide surface 39 can be easily pulled out even when the seat 2B is in either of the front and rear positions.

  Note that the structure of the holding portion for holding the webbing 17 on the guide surface 39 may be a configuration other than the restriction wall 55. However, as in this embodiment, the restriction wall 55 protrudes from the pedestal portion 38. When the displacement is restricted to the webbing 17 by the restriction wall 55, the construction cost is extremely simple, so that the manufacturing cost of the vehicle can be further reduced.

  Further, in the interior structure of this embodiment, the restriction protrusion 56 that restricts the displacement of the upper side of the webbing 17 is integrally formed on the outer surface of the restriction wall 55 in the vehicle width direction. It is possible to more reliably prevent the webbing 17 from falling off the guide surface 39 due to lifting to the side or the like.

  In the case of the interior structure of this embodiment, the bent piece 45a on the upper side of the assist grip 42 is joined to the side position of the guide surface 39 in the front edge of the pedestal portion 38, and the bent piece 45a Since the upper edge protrudes upward and forward from the guide surface 39 to form the restriction wall 55, it is possible to prevent the webbing 17 from falling off from the guide surface 39 while sharing parts with the assist grip 42. it can. Therefore, this configuration can further reduce the manufacturing cost.

  In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary. For example, although the above embodiment is a vehicle having three rows of seats, it can be similarly applied to a vehicle having two rows of seats.
