  Next, the operation of the sheet apparatus 10 according to the present embodiment will be described. In the initial stage, the seat 14 is in a state of facing forward, is in a state of being inclined so that the upper portion of the seat back 43 is positioned slightly rearward, and the seat cushion 46 is substantially horizontal. Be in a sitting position. The slide lock mechanism 20, the seat cushion lock mechanism 60, and the reclining lock mechanism are all in a locked state. Further, in this state, the base 40 and the slider 13 are positioned behind the center portion of the seat cushion 46.

  As shown in FIG. 1, when the occupant M pulls up the lower end side of the operation lever 94 from the tailgate TG side, as shown in FIG. 4, the slide lock switching wire 32, the cushion lock switching wire 78, and the seat back lock switching wire. 92 is pulled, and the locks by the slide lock mechanism 20, the seat cushion lock mechanism 60, and the reclining lock mechanism (not shown) are all released.

  Accordingly, the seat 14 can be moved in the front-rear direction, and the seat cushion 46 in the seating position is flipped up to the seat back 43 side by the urging force of the jump spring 56, and the seat back 43 is tilted forward. It will be. The raised seat cushion 46 comes into contact with the seat back 43 that is tilted forward and stops in a folded state. Specifically, the sheet 14 folded in this manner is contracted to a length substantially the same as that of the base 40. In this state, the lock portion 66 of the latch member 68 of the seat cushion lock mechanism 60 is located between the two lock recesses 61 and 62 of the gear member 63. The fitting is impossible.

Next, when the pulling force of the operating lever 94 is released, the three wires 32, 78, and 92 are loosened.
As described above, when the slide lock switching wire 32 is loosened, the operation lever 28 of the slide lock mechanism 20 is rotated counterclockwise by a spring (not shown) to return to the original position (position where the operation piece portion 29 is substantially horizontal). ) And the downward pressing of the swing arm 25 by the operating lever 28 is released. As a result, the swing arm 25 swings clockwise, and the lock member 21 is fitted into the slide lock hole 18. That is, the slide lock mechanism 20 is brought into the locked state, and the sliding of the seat 14 is restricted.

  When the cushion lock switching wire 78 is loosened as described above, the tip-up lever 72 of the seat cushion lock mechanism 60 is swung counterclockwise by the biasing force of the lever spring 76 and the latch member 68 is rotated clockwise. By doing so, the lock portion 66 moves backward. Here, the gear member 63 is configured such that the lock recess 62 can be fitted to the lock portion 66 of the latch member 68 when the seat cushion 46 is slightly rotated in conjunction with the rising motion of the seat back 43 as described above. Therefore, the lock portion 66 and the lock recess 62 moving rearward are fitted to each other. That is, the seat cushion lock mechanism 60 is brought into the locked state, and the rotation of the seat cushion 46 is restricted.

  The seat back 43 is moved upright by a reclining lock mechanism (not shown) so as not to be separated from the seat cushion 46 in which the lock portion 66 of the latch member 68 is fitted in the lock recess 62. A pivotable angle is set. In other words, the seat back 43 in the forward-turned state can be turned only by a predetermined amount by the reclining lock mechanism.

  Therefore, for example, as shown in FIG. 8, by moving the third row of seats 14 forward and releasing the pulling force of the operation lever 94 at a predetermined position, the longitudinal movement of the seats 14 is locked, The positions of the seat cushion 46 and the seat back 43 are locked. For this reason, it is easy to fix the seat 14 to a predetermined position.

  Further, when the seat 14 is moved back and forth as shown in FIG. 5 and the positions of the seat cushion 46 and the seat back 43 are locked, the slide lock release lever 100 provided on the front side surface 99 of the seat cushion 46 is shown in FIG. When pulled outward as shown in FIG. 6, the second slide lock switching wire 37 is pulled upward, and the lock by the slide lock mechanism 20 is released. As a result, only the forward / backward movement lock of the seat 14 is released, and the seat 14 is in a state in which only the forward / backward movement can be performed. Therefore, the seat 14 can be moved to a desired position while the seat cushion 46 and the seat back 43 are folded.

  Then, after the seat 14 is moved in this way, as shown in FIG. 5, when the tensile force applied to the slide lock release lever 100 is released, the slide lock release lever 100 is restored to the original state by the urging force of a spring (not shown). And the second slide lock switching wire 37 is loosened, the slide lock mechanism 20 is locked, and the forward / backward movement of the seat 14 is restricted. That is, it is possible to easily adjust the position of the seat 14 in the front-rear direction while the seat 14 is folded by simply operating the slide lock release lever 100 as appropriate.

  Further, as shown in FIG. 7, when the cushion lock release lever 103 is pulled outward, the second cushion lock switching wire 82 is pulled upward, and the lock by the seat cushion lock mechanism 60 is released. As a result, only the seat cushion 46 can be rotated, so that the seat cushion 46 can be manually positioned at the seating position or the jumping position. Then, for example, when the tension applied to the cushion lock release lever 103 is released with the seat cushion 46 positioned at the seating position, the cushion lock release lever 103 is attached with a spring (not shown) as shown in FIG. The second cushion lock switching wire 82 is loosened by the force and is loosened, the seat cushion lock mechanism 60 is locked, and the seat cushion 46 is fixed at the seating position.

According to the above, the following effects can be obtained in the present embodiment.
The operation lever 94 interlocks and releases the lock by the slide lock mechanism 20, the lock by the seat cushion lock mechanism 60, and the lock by the reclining lock mechanism, thereby enabling the seat 14 to move in the front-rear direction and the seating position. The seat cushion 46 in the position is flipped up to the seat back 43 side by the urging force of the jump spring 56, and the seat back 43 is tilted forward (see FIG. 4). Therefore, the space occupied by the seat device 10 itself can be further reduced, and as a result, a large cargo space can be secured (see FIG. 8).

Further, since the above-described unlocking can be performed with one operation lever 94, the unlocking by the slide lock mechanism and the seat cushion locking mechanism and the unlocking by the reclining lock mechanism are separately performed as in the prior art. It is not necessary to perform a complicated operation such as, and the operation can be facilitated.
Further, since the operation lever 94 is provided on the back side of the base 40, even if the seat cushion 46 and the seat back 43 are rotated, the mounting position of the operation lever 94 does not change, and good operability is obtained. It is done.

In addition, this invention is implemented in various forms, without being limited to the said embodiment.
For example, in the above-described embodiment, the three wires 32, 78, and 92 are connected to the operation lever 94 and are pulled at the same time. However, the operation lever 94 may be modified as follows.

  First, as shown in FIG. 9, a switching lever 97 that is rotatably supported by the support shaft 48 of the seat back 43 is provided. The switching lever 97 includes an input piece 95 that extends obliquely forward and upward from the support shaft 48 to be engageable with the operation bracket 87, and an operation piece that extends from the support shaft 48 toward the back surface of the seat back 43. 96. The slide lock switching wire 32 and the cushion lock switching wire 78 that are connected to the operation lever 94 in the above embodiment are connected to the lower part of the operating piece 96. The switching lever 97 is always held at a predetermined position by a spring (not shown). Further, only the seat back lock switching wire 92 is connected to the operation lever 94.

When the lower end side of the operation lever 94 is pulled up, the seat back lock switching wire 92 is pulled, so that the lock by the reclining mechanism (not shown) is released and the seat back 43 is tilted forward.
Further, when the seat back 43 is tilted from the rearward state as shown in FIG. 9 to the forward state as shown in FIG. 10, the input piece 95 is pushed forward by the operation bracket 87 of the seatback 43, and the switching is performed. The lever 97 rotates counterclockwise, and the operating piece 96 rises. As a result, the slide lock switching wire 32 and the cushion lock switching wire 78 are pulled rearward by the operating piece 96, and the locks by the slide lock mechanism 20 and the seat cushion lock mechanism 60 are released, respectively. When the seat back 43 is manually returned to the rear side, the pressing of the input piece 95 by the operating bracket 87 is released, and the switching lever 97 is returned to the original position by a spring (not shown) (FIG. 9). reference).

  Therefore, in the seat device configured as described above, when the lower end portion of the operation lever 94 is pulled up by the occupant, the lock by the reclining lock mechanism (not shown) is released, and the seat back 43 is tilted forward (see FIG. 10). Accordingly, the lock by the slide lock mechanism 20 and the seat cushion lock mechanism 60 is released, and the seat 14 can be moved in the front-rear direction, and the seat cushion 46 in the seating position is lifted up. It is flipped up to the seat back 43 side by the urging force of 56 (see FIG. 10).

  The raised seat cushion 46 comes into contact with the seat back 43 that is tilted forward and stops in a folded state. Specifically, the sheet 14 folded in this manner is contracted to a length substantially the same as that of the base 40. In this state, the lock portion 66 of the latch member 68 of the seat cushion lock mechanism 60 is located between the two lock recesses 61 and 62 of the gear member 63. The fitting is impossible. Thus, also by this modification, the same effect as the above-described embodiment can be obtained.

  In the embodiment, the lock by the lock mechanism such as the slide lock mechanism 20 is released via the wire such as the slide lock switching wire 32. However, the present invention is not limited to this, and for example, via the link mechanism. Then, the lock by the lock mechanism may be released.

  Furthermore, in the above-described embodiment, the seat cushion 46 is tipped up by the connecting link 53, the jump spring 56, etc., but the present invention is not limited to this, and the seat cushion 46 is tipped up using a damper such as an air damper. You may let them. In addition, when the air damper is used in this way, the seat cushion 46 can be tipped up slowly, so that a sense of quality can be enhanced.
