  By the way, in a vehicle in which three seats are arranged on the left and right, it is desired that a wider passage is formed between the left and right seats so that the user can easily go back and forth between the seats.

  Therefore, an object of the present invention is to create a wide passage extending in the front-rear direction in a seat unit in which three seats are arranged side by side on the left and right.

  The present invention for solving the above-described problems includes a first sheet provided on the vehicle body, a second sheet provided in the width direction of the vehicle body with respect to the first sheet, and a space between the first sheet and the second sheet. And a first slide rail mechanism that supports one of the first sheet and the second sheet so as to be slidable in the width direction. In this seat unit, the center seat has a seat cushion and a seat back. And, the center seat is supported by the first seat, a seated state in which the seat back is raised with respect to the seat cushion, and a first folded state in which the seat back is folded forward from the seated state and the seat back is overlapped with the seat cushion, It is configured to be movable between a first folded state and a second folded state in which the seat cushion and the seat back overlap with each other and folded to the first seat side. The first slide rail mechanism is provided such that the one of the first seat and the second seat is movable between the first position and a second position outside the width direction of the vehicle body from the first position. It has been.

  According to such a structure, the center sheet | seat can be made into the 2nd folding state, and the channel | path extended in the front-back direction between a 1st sheet | seat and a 2nd sheet | seat can be made. Then, when the center seat is in the second folded state, one of the first seat and the second seat is slid to the second position on the outer side in the width direction of the vehicle body, thereby extending between the left and right seats. A wide passage can be made.

  In the seat unit described above, the first slide rail mechanism supports the first seat, the center seat is in the second folded state, and the first seat is in the outermost side in the width direction of the vehicle body. The end of the slide rail mechanism on the second sheet side is preferably farther from the second sheet in the width direction than the end of the center sheet on the second sheet side.

  According to such a configuration, when the center seat is in the second folded state and the first seat is slid to the outermost side in the width direction of the vehicle body, the end portion on the second seat side of the first slide rail mechanism is Since the center sheet is farther from the second sheet in the width direction than the second sheet side end of the center sheet, the first slide rail mechanism does not protrude from the center sheet when the center sheet is looked down from above. Therefore, when the occupant passes through the passage between the first seat and the second seat, the first slide rail mechanism is less likely to get in the way.

  In the above-described seat unit, the first slide rail mechanism may support the second seat. In this case, in the state where the second seat is at the outermost side in the width direction, the end portion on the first seat side of the first slide rail mechanism is more than the end portion on the first seat side of the seat cushion of the second seat. It is desirable to be far from the first sheet in the width direction.

Therefore, when the occupant passes through the passage between the first seat and the second seat, the first slide rail mechanism is less likely to get in the way.

  The above-described seat unit may further include a second slide rail mechanism that supports the other of the first sheet and the second sheet so as to be slidable in the width direction.

  If both the first seat and the second seat are slidable in the width direction of the vehicle body, the center passage can be further widened.

  The above-described sheet unit further includes a biasing member that biases the one of the first sheet and the second sheet toward the first position in a state where the one of the first sheet and the second sheet is in the second position. It is desirable to provide.

  According to such a configuration, when the one of the first sheet and the second sheet is moved to the second position, the one sheet is biased toward the first position by the biasing member. It becomes easy to return the one sheet to the first position.

  The above-described seat unit may further include a third seat disposed in front of the first seat, and the first slide rail mechanism may support the first seat. In this case, when the center sheet is in the second folded state and the first sheet is at the outermost side in the width direction, the end portion on the second sheet side of the center sheet is the end on the inner side in the width direction of the third sheet. It is desirable to be located on the outer side in the width direction than the portion.

  According to such a configuration, a sufficiently wide passage can be formed between the center sheet and the second sheet.

  The sheet unit described above may further include a third sheet disposed in front of the first sheet and a fourth sheet disposed in front of the second sheet. In this case, when the center sheet is in the second folded state and the first sheet and the second sheet are at the outermost side in the width direction, the distance between the center sheet and the second sheet is the third sheet and the fourth sheet. It is desirable that it is larger than the interval.

  According to such a configuration, a sufficiently wide passage can be formed between the center sheet and the second sheet.

  The seat unit described above further includes a hinge mechanism that rotatably supports the center seat on the first seat, and a lock mechanism that holds the first seat in the first position. The sheet may be supported. In this case, it is desirable that the lock mechanism is disposed at a position that does not overlap with the hinge mechanism as viewed from above and below.

  According to such a configuration, the hinge mechanism and the lock mechanism are unlikely to interfere with each other.

  The above-described seat unit may further include a hinge mechanism that rotatably supports the center seat on the first seat, and the first slide rail mechanism may support the first seat. In this case, it is desirable that the urging member is disposed at a position that does not overlap with the hinge mechanism as viewed from above and below.

  According to such a configuration, interference between the biasing member and the hinge mechanism can be suppressed.

  In the seat unit described above, the first slide rail mechanism may support the first seat. In this case, it is desirable that the urging member is disposed at the outer end in the width direction in the first slide rail mechanism.

  According to such a structure, it can suppress that a biasing member interferes with a center mechanism, the hinge mechanism etc. which support a center sheet | seat.

  In the above-described seat unit, the center seat may be configured to be movable between the first folded state and the second folded state in which the seat cushion and the seat back overlap and rise to the first seat side.

As shown in FIG. 5, the lower rails 210 and 220 of the lateral slide rail mechanism 20 are fixed to the upper rails 115 and 125 of the front and rear slide rail mechanism 10. On the other hand, the upper rails 215 and 225 of the lateral slide rail mechanism 20 are fixed to the frame of the seat cushion S31. Further, the lower rails 110 and 120 of the front and rear slide rail mechanism 10 are fixed to the floor F of the vehicle body B by a pair of brackets 19 that are separated front and rear.
The front and rear slide rail mechanism 10 and the horizontal slide rail mechanism 20 allow the right rear seat S3 to slide and move back and forth and right and left.

  As shown in FIG. 6, the lock mechanism 30 includes a lock lever 31 provided on the upper rail 215, a torsion spring 32, and an engagement groove 210 </ b> A provided on the lower rail 210. The lock lever 31 includes a shaft portion 31A, an engagement portion 31B fixed to the shaft portion 31A, and an operation portion 31C. The shaft portion 31 </ b> A is rotatably supported by a bracket 33 fixed to the upper rail 215. For this reason, the engaging part 31B and the operation part 31C can rotate integrally with the shaft part 31A.

  The engaging portion 31B has a plate shape orthogonal to the axial direction of the shaft portion 31A and can be engaged with the engaging groove 210A. The torsion spring 32 constantly urges the lock lever 31 in the direction in which the engaging portion 31B engages with the engaging groove 210A.

  The cable 49 includes an inner cable 49A, a tubular outer cable 49B through which the inner cable 49A passes, and a columnar engagement portion 49C provided at one end of the inner cable 49A. The engaging portion 49 </ b> C is engaged with the operation portion 31 </ b> C of the lock lever 31. Further, an engagement portion (not shown) is also provided at the other end of the inner cable 49A, and this engagement portion is engaged with the operation lever 40, so that the inner cable 49A is moved by operating the operation lever 40. Is possible. Accordingly, when the operation lever 40 is operated to be pulled up, the lock lever 31 is rotated and the engaging portion 31B can be detached from the engaging groove 210A. Further, when the operation lever 40 is not pulled up, if the position of the engaging portion 31B is aligned with the engaging groove 210A, the engaging portion 31B engages with the engaging groove 210A to lock the position of the left rear seat S4. It is possible.

The engagement groove 210A is disposed at a position where the engagement portion 31B can be engaged when the right rear seat S3 is in the first position. That is, the lock mechanism 30 can hold the seat cushion S31 in the first position.
The front / rear slide rail mechanism 10 is also provided with a known locking mechanism (not shown) so that the seat cushion S31 can be held at a plurality of positions in the front / rear direction.

  As shown in FIG. 7, the slide rail mechanism 21 is provided with a spring 50 as an example of an urging member. The spring 50 is a compression coil spring. The spring 50 is disposed inside the slide rail mechanism 21. Specifically, as shown in FIG. 6, the lower rail 210 has a square cylindrical shape as a whole, and has a slit 210 </ b> C extending in the left-right direction on the upper surface. The spring 50 is disposed inside the cylindrical shape of the lower rail 210.

  As shown in FIG. 7, a support wall 230 that rises upward is formed at the right end of the lower rail 210. One end of the spring 50, here the right end, is in contact with and engaged with the support wall 230. The other end of the spring 50, here the left end, is in contact with and engaged with the right end of the upper rail 215. The spring 50 always urges the seat cushion S31 toward the left. That is, the spring 50 can bias the seat cushion S31 from the second position toward the first position, thereby assisting the movement of the seat cushion S31 from the second position to the first position.

  A damper 60 as an example of a speed reduction mechanism is disposed inside the left end portion of the lower rail 210. The damper 60 is fixed to the lower rail 210. The damper 60 includes a cylinder 61 and a piston rod 62 that is slidable to the left and right with respect to the cylinder 61. The cylinder 61 is filled with a liquid such as gas or oil, and the piston rod 62 can move with resistance against the cylinder 61 by the resistance of the fluid. The damper 60 is provided with a spring (not shown) inside, and this spring constantly urges the piston rod to push outward, in this case, to the right. The stroke amount of the piston rod 62 is smaller than the movable amount of the upper rail 215 in the left-right direction. That is, as shown in FIG. 8, when the upper rail 215 moves to the right by a predetermined amount or more, the piston rod 62 is separated from the upper rail 215. Therefore, the damper 60 slows the movement of the seat cushion S31 only when the seat cushion S31 approaches the first position from the second position, that is, when the seat cushion S31 is at a predetermined distance from the first position. It functions as a deceleration mechanism.

  The slide rail mechanism 22 is also provided with a spring 50 and a damper 60 in the same manner as the slide rail mechanism 21. That is, the spring 50 and the damper 60 are provided in each of the pair of lateral slide rail mechanisms 20.

The lock mechanism 30 is disposed at a position that does not overlap with the hinge mechanism 2 when viewed from above and below. For this reason, it is difficult for the hinge mechanism 2 and the lock mechanism 30 to interfere with each other.
The spring 50 is also disposed at a position that does not overlap with the hinge mechanism 2 when viewed from the top and bottom. For this reason, interference between the spring 50 and the hinge mechanism 2 can be suppressed.
Further, the spring 50 is disposed at the outer end of the lateral slide rail mechanism 20 in the width direction. For this reason, it can suppress that the spring 50 interferes with the center sheet | seat SC, the hinge mechanism 2, etc. FIG.

  The engagement groove 210A of the slide rail mechanism 21 described above is provided only at one location corresponding to the first position of the seat cushion S31. For this reason, the position of the seat cushion S31 is not held in the second position. Further, the slide rail mechanism 21 supports the seat cushion S31 so as to be movable only within the range from the first position to the second position, and the seat cushion S31 can be moved at any position between the first position and the second position. The position is not maintained.

  In the state where the center seat SC is in the second folded state and the right rear seat S3 is in the second position, that is, the outermost side in the width direction of the vehicle body B, the end of the lateral slide rail mechanism 20 on the left rear seat S4 side The portion 240 is farther from the second seat in the width direction than the end portion SC9 on the left rear seat S4 side of the center seat SC. That is, when the center seat SC is in the second folded state and the right rear seat S3 is in the second position, when the right rear seat S3 and the center seat SC are looked down from above, the lateral slide rail mechanism 20 Hidden in S3 and center sheet SC.

  In particular, as shown in FIG. 10A, in the present embodiment, the center seat SC is in the second folded state, and the right rear seat S3 is in the second position, that is, the outermost side in the width direction of the vehicle body B. In this state, the end 240 on the left rear seat S4 side of the lateral slide rail mechanism 20 is closer to the second seat in the width direction than the end S39 on the left rear seat S4 side of the seat cushion S31 of the right rear seat S3. Far away. That is, when the center seat SC is in the second folded state and the right rear seat S3 is in the second position, when the right rear seat S3 and the center seat SC are looked down from above, the lateral slide rail mechanism 20 Hidden in S3.

  Further, when the center seat SC is in the second folded state and the right rear seat S3 is at the outermost side in the width direction, the end SC9 on the left rear seat S4 side of the center seat SC is the width of the right front seat S1. It is located on the outer side in the width direction than the end portion S19 on the inner side in the direction. For this reason, it is possible to make a sufficiently wide passage PS between the center seat SC and the left rear seat S4.

  Further, when the center seat SC is in the second folded state and the right rear seat S3 and the left rear seat S4 are at the outermost side in the width direction, the distance between the center seat SC and the left rear seat S4, that is, the center seat The distance between the SC end SC9 and the left rear seat S4 is larger than the distance between the right front seat S1 and the left front seat S2. For this reason, it is possible to make a sufficiently wide passage PS between the center seat SC and the left rear seat S4.

  As shown in FIG. 5, the horizontal slide rail mechanism 20 is positioned below the center seat SC in the second folded state. For this reason, the interference between the lateral slide rail mechanism 20 and the center seat SC can be suppressed.

As described above, the left rear seat S4 is configured symmetrically with the right rear seat S3. FIG.
As shown in FIG. 4, the left rear seat S4 has a second slide rail mechanism (when the right rear seat S3 is supported by the first slide rail mechanism) or a first slide rail mechanism (the right rear seat S3 is the second slide rail mechanism). The horizontal slide rail mechanism 20 as an example is instructed to be movable left and right. Specifically, the horizontal slide rail mechanism 20 includes a rear slide rail mechanism 21 and a front slide rail mechanism 22, which allows the left rear seat S4 to be moved to a first position indicated by a solid line and two points. It is supported for sliding movement with a second position on the outer side in the width direction of the vehicle body B with respect to the first position indicated by the chain line.

  As shown in FIG. 10A, in the state where the left rear seat S4 is in the second position, that is, the outermost side in the width direction of the vehicle body B, the end 240 on the right rear seat S3 side of the lateral slide rail mechanism 20 is Further, it is farther from the right rear seat S3 in the width direction than the end portion S49 on the right rear seat S3 side of the seat cushion S41 of the left rear seat S4.

The operation and effect of the sheet unit SS configured as described above will be described.
When the right rear seat S3 and the left rear seat S4 are in the first position as shown in FIGS. 1 and 2 and the center seat SC is in the seated state, the right rear seat S3 and the left rear seat S4 are arranged without gaps, It is not possible to pass between the right rear seat S3 and the left rear seat S4. As shown in FIG. 6, in the lock mechanism 30, the engaging portion 31B is engaged with the engaging groove 210A of the lower rail 210, and the right rear seat S3 and the left rear seat S4 are held in the first position. .

  In this state, when going back and forth between the seats in the second row, first, as shown in FIG. 3, the seat back SC2 of the center seat SC is folded forward and overlapped with the seat cushion SC1, to be in the first folded state. Further, as shown in FIG. 4, the overlapping seat back SC2 and seat cushion SC1 are raised to the right rear seat S3 side to be in the second folded state.

  Then, when the operating levers 40 of the right rear seat S3 and the left rear seat S4 are raised, the lock lever 31 rotates and the engaging portion 31B is disengaged from the engaging groove 210A so that the right rear seat S3 and the left rear seat S4 are in the vehicle body. It becomes possible to slide to the outside in the width direction of B (that is, the left-right direction). Therefore, when the right rear seat S3 is pushed outward in the width direction of the vehicle body B with the operation lever 40 raised, the seat cushion S31 moves from the first position shown in FIG. 7 to the second position shown in FIG. The same applies to the left rear seat S4.

  In the second position, the spring 50 is in a contracted state. The piston rod 62 of the damper 60 extends from the cylinder 61, but the upper rails 215 and 225 move away from the piston rod 62 due to the large movement of the upper rails 215 and 225.

  As shown in FIG. 10A, when the center seat SC is in the second folded state and the right rear seat S3 and the left rear seat S4 are located at the second position, the space is wide between the right rear seat S3 and the left rear seat S4. A passage PS is formed. Accordingly, the occupant H can move through the passage PS, for example, from the front of the left rear seat S4 to the rear of the right rear seat S3. At this time, the end 240 on the left rear seat S4 side of the lateral slide rail mechanism 20 of the right rear seat S3 is the left rear seat in the width direction of the vehicle body B more than the end SC9 on the left rear seat S4 side of the center seat SC. Since it is far from S4, when looking down at the center seat SC from above, the lateral slide rail mechanism 20 does not protrude from the center seat SC. Therefore, when the occupant H passes through the passage PS between the right rear seat S3 and the left rear seat S4, the lateral slide rail mechanism 20 of the right rear seat S3 is less likely to get in the way.

  In particular, in the present embodiment, the end 240 on the left rear seat S4 side of the lateral slide rail mechanism 20 of the right rear seat S3 is more than the end S39 on the left rear seat S4 side of the seat cushion S31 of the right rear seat S3.

  In the present embodiment, since the spring 50 is disposed inside the lateral slide rail mechanism 20, the occupant H can be prevented from touching the spring 50.

  In the present embodiment, since the positions of the right rear seat S3 and the left rear seat S4 are not maintained in the second position, after the right rear seat S3 and the left rear seat S4 are moved to the second position, the first position Even if the operation of returning the right rear seat S3 and the left rear seat S4 is not performed, it is easy to return to the first position.

  Furthermore, in the present embodiment, the lateral slide rail mechanism 20 supports the right rear seat S3 and the left rear seat S4 so as to be movable only within the range from the first position to the second position. Since the positions of the right rear seat S3 and the left rear seat S4 are not maintained at any position in between, the halfway between the first position used during operation of the vehicle C and the second position temporarily moved It is possible to prevent the right rear seat S3 and the left rear seat S4 from being located at the correct positions.

  In addition, even when the seat unit SS of the present embodiment gains momentum in the movement of the seat cushion from the second position toward the first position by the spring 50, the speed of the seat cushion is reduced by the damper 60 when approaching the first position. Therefore, the speed when the right rear seat S3 and the left rear seat S4 reach the first position can be reduced to realize a quiet operation.

  Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and can be appropriately modified and implemented.

  In the embodiment, two slide rail mechanisms 21 and 22 whose operation is assisted by the biasing member are provided, but one may be used. In the embodiment, the horizontal slide rail mechanism 20 is provided on the front and rear slide rail mechanism 10. However, the front and rear slide rail mechanism 10 may be provided on the horizontal slide rail mechanism 20.

  Further, the lateral slide rail mechanism 20 may have the end on the passage PS side slightly protruding from the passage PS when the right rear seat S3 or the left rear seat S4 is in the second position.

  In the embodiment, both the right rear seat S3 and the left rear seat S4 are configured to be slidable left and right, but only one of the right rear seat S3 and the left rear seat S4 is slidable to the left and right. It may be configured.
