  However, there is a desire to increase the space in the vehicle interior by bringing the seat cushion at the storage position closer to the wall surface. Further, since the cover is provided integrally with the seat cushion, there is a case where it becomes an obstacle when the seat cushion is brought close to the wall surface. Therefore, there has been a need for a retractable vehicle seat that can easily bring the seat cushion close to the wall surface.

  In order to solve the above problems, the present invention is a retractable seat for a vehicle having a configuration as described in each claim. According to one aspect, the present invention provides a seat cushion, a connecting member having a first end portion rotatably connected to a side portion of the seat cushion and a second end portion rotatably connected to a vehicle wall surface, The first cover is rotatably connected to the vehicle wall surface so that the connecting member can be covered from above when the seat cushion is moved downward from the storage position along the vehicle wall surface to a use position parallel to the vehicle floor surface.

  Accordingly, the angle of the seat cushion can be adjusted with respect to the vehicle wall surface at two locations of the first end portion and the second end portion of the connecting member. Therefore, the connecting member is rotated with respect to the vehicle wall surface around the second end to move the seat cushion from the use position toward the storage position, and the seat cushion is used as the connecting member around the first end of the connecting member. By rotating with respect to the seat cushion, the seat cushion can be suitably brought close to the wall surface. Moreover, since the first cover can rotate with respect to the vehicle wall surface when the seat cushion is brought close to the vehicle wall surface, the first cover is less likely to get in the way. Moreover, the first cover can be configured simply.

  As shown in FIG. 1, an operation lever 14 that is operated when the seat 1 is moved from the use state to the retracted state is provided on the lower surface of the rear portion of the seat cushion 2. By operating the operation lever 14, the reclining device 16 and the lock device 15 connected to the operation lever 14 by a cable are unlocked. The seat back 3 is urged by an urging member provided between the seat back 2 and overlaps the seat cushion 2.

  When the locking device 15 is released, the seat cushion 2 can move with respect to the vehicle floor 21 as shown in FIG. The seat cushion 2 moves toward the vehicle wall surface 22 by the first connecting member 4 urged by the urging member 12. The leg 8 is pulled by a cable connected to the vehicle wall surface 22, rotates against the urging member 8 c with respect to the seat cushion 2, and runs along the bottom surface of the seat cushion 2.

  As shown in FIGS. 2 and 3, the seat cushion 2 is guided by the connecting members 4 and 5 and moves from the use position to the storage position. The connecting members 4 and 5 rotate around the second connecting portions 4 b and 5 b to move the seat cushion 2 from the side of the connecting members 4 and 5 to above the connecting members 4 and 5. The first connecting portions 4a and 5a of the connecting members 4 and 5 are close to the vehicle wall surface 22 beyond the second connecting portions 4b and 5b. As a result, the seat cushion 2 comes close to the vehicle wall surface 22.

  As shown in FIGS. 2 and 3, when the seat cushion 2 is moved from the use position to the storage position, the connecting members 4 and 5 cooperate to rotate the seat cushion 2 clockwise with respect to the first connecting portions 4a and 5a. Rotate. Accordingly, the seat cushion 2 is substantially parallel to the vehicle wall surface 22 and can be brought closer to the vehicle wall surface 22.

  As shown in FIGS. 2 and 3, the first cover 6 is pushed by the second cover 7 and rotates upward by changing the seat 1 from the use state to the retracted state. The tip 6b of the first cover 6 moves from the upper end 7a of the second cover 7 to the upper surface 3a of the seat back 3, and is pushed by the upper surface 3a. Thus, the first cover 6 rotates upward against the biasing member 13 and is positioned between the seat back 3 and the vehicle wall surface 22.

  When changing the seat 1 from the retracted state to the used state, the seat cushion 2 is lowered toward the vehicle floor 21 as shown in FIG. As a result, the leg 8 stands up with respect to the seat cushion 2, and the locking device 15 is locked to the anchor 25. The first cover 6 rotates with respect to the vehicle wall surface 22 by the urging force of the urging member 12 to cover the connecting members 4 and 5 from above.

  As described above, the retractable seat 1 for a vehicle includes the seat cushion 2, the connecting members 4 and 5, and the first cover 6 as shown in FIG. The connecting members 4 and 5 have a first end portion rotatably connected to the side portion of the seat cushion 2 and a second end portion rotatably connected to the vehicle wall surface 22. The first cover 6 is configured to cover the connecting members 4, 5 from above when the seat cushion 2 is moved downward from a storage position along the vehicle wall surface 22 to a use position parallel to the vehicle floor surface 21. To be rotatably connected.

  Accordingly, the angle of the seat cushion 2 can be adjusted with respect to the vehicle wall surface 22 at two locations of the first end portion and the second end portion of the connecting members 4 and 5. Therefore, the connecting members 4 and 5 are rotated with respect to the vehicle wall surface 22 around the second end to move the seat cushion 2 from the use position toward the storage position, and the first ends of the connecting members 4 and 5 are moved. The seat cushion 2 can be suitably brought close to the vehicle wall surface 22 by rotating the seat cushion 2 with respect to the connecting members 4 and 5 at the center. Moreover, since the 1st cover 6 can rotate with respect to the vehicle wall surface 22 when making the seat cushion 2 adjoin to the vehicle wall surface 22, it is hard to become obstructive. Moreover, the first cover 6 can be configured simply.

  As shown in FIG. 2, the second cover 7 is integrally provided on the seat cushion 2. The second cover 7 rises to the side of the connecting members 4 and 5 when the seat cushion 2 is set to the use position, covers the side of the connecting members 4 and 5, and the front end portion 6 b of the first cover 6 contacts. The upper end 7a is provided. Therefore, the side of the connecting members 4 and 5 is covered with the second cover 7, and the upper part of the connecting members 4 and 5 is covered with the first cover 6. Since the 1st cover 6 and the 2nd cover 7 contact | abut, it can cover the connection members 4 and 5 with a small capacity | capacitance compared with the case where these overlap.

  As shown in FIG. 2, the seat back 3 is connected to the seat cushion 2 so that the angle can be adjusted. The seat back 3 is adjacent to the second cover 7 by overlapping the seat back 3 on the seat cushion 2 in the use position. The second cover 7 is set to the same height as the upper surface 3a of the adjacent seat back 3, and when the seat cushion 2 is moved from the use position to the storage position, the second cover 7 is moved from the upper end 7a of the second cover 7 to the seat back 3. The tip 6b of the first cover 6 is allowed to move to the upper surface 3a.

  Therefore, the seat cushion 2 can be smoothly moved from the use position to the storage position. Further, since the second cover 7 is set at the same height as the upper surface 3a of the seat back 3, the amount of the second cover 7 protruding from the seat back 3 is small. Therefore, as shown in FIG. 3, the second cover 7 is unlikely to get in the way when the seat cushion 2 and the seat back 3 are brought close to the vehicle wall surface 22.
