As shown in FIG. 1, a vehicle turning seat (hereinafter simply referred to as “turning seat”) 12 according to the present embodiment includes a seat cushion 14 on which an occupant sits. A seat back 16 that supports the upper body of a seated occupant is provided at the rear of the seat cushion 14, and a headrest 20 that supports the head of the seated occupant (see FIG. 4). ) Is provided.

  On the other hand, a pair of seat slides 24 extend along the vehicle front-rear direction on the vehicle body floor 22 of the vehicle 10, and a slide rail extends along the vehicle front-rear direction above the seat slide 24. 26 are provided. On the slide rail 26, a rectangular plate-shaped base member 28 as a pedestal is disposed along a substantially horizontal direction.

  The base member 28 is movable along the vehicle longitudinal direction via the slide rail 26. A fixed shaft 30 is fixed to the base member 28, and a disk-shaped rotary table 32 is supported on the fixed shaft 30 so as to be rotatable around the fixed shaft 30. The rotary sheet 12 is fixed to the rotary table 32, and the rotary sheet 12 can be rotated along the horizontal direction by the rotation of the rotary table 32.

  Specifically, as shown in FIG. 1, the rotating seat 12 includes a vehicle running position Q in which the front end portion 14A of the seat cushion 14 faces the front side in the vehicle front-rear direction, and a seat cushion as shown in FIG. The front end portion 14 </ b> A of the vehicle 14 can turn between the vehicle entry / exit position R facing the side door 34 side. In the vehicle travel position Q and the vehicle entry / exit position R, a stopper (not shown) is provided, and excessive rotation of the turntable 32 is restricted.

  Further, as shown in FIG. 5C, the base member 28 is provided with, for example, a solenoid 36. In a state where the solenoid 36 is not energized, the plunger 40 constituting the solenoid 36 is pressed and protrudes by a biasing force of a spring (not shown) in the case 42. In a state where the plunger 40 protrudes from the case 42, the plunger 40 is engaged with a hole 32 </ b> A formed in the rotary table 32. With the plunger 40 engaged with the hole portion 32 </ b> A, the rotary table 32 is locked, and the rotary table 32 and the rotary sheet 12 are not rotatable with respect to the base member 28.

  In this state, when the solenoid 36 is energized, the plunger 40 is pulled into the case 42 while compressing the spring, as shown in FIG. Thereby, the engagement state of the plunger 40 with the rotary table 32 is released. That is, the rotary table 32 is in a so-called unlocked state, and the rotary table 32 and the rotary sheet 12 are rotatable with respect to the base member 28.

  From the above, in the present embodiment, as shown in FIG. 1, when the rotating seat 12 is in the vehicle traveling position Q, the solenoid 36 is set not to be energized, and the rotating seat 12 is rotated. In addition, the solenoid 36 needs to be set to be energized.

  For example, in the present embodiment, the solenoid 36 is electrically connected to the control device 38 (see FIG. 6). The control device 38 is electrically connected to a shift lever 48, and a signal indicating the position position of the shift lever 48 is input thereto.

  As shown in FIG. 1, when the shift lever 48 is moved to a parking range (hereinafter referred to as “P range”), for example, the contact portion provided on the shift lever 48 is changed to the contact portion provided at the P range position. A predetermined signal is input to the control device 38 upon contact. Thus, the operation switch 46 is set to be operable.

  The operation switch 46 is disposed, for example, on the instrument panel 44, the rotating sheet 12, and the like, and is controlled by the control device 38. Here, as an example, the control device 38 is provided with a relay switch (not shown). A circuit connecting the contact point provided on the shift lever 48 and the solenoid 36 is opened and closed by the relay switch. When the shift lever 48 moves to the P range and the operation switch 46 is operated, the operation switch 46 is activated, the circuit is closed, and the solenoid 36 can be energized. That is, the plunger 40 is pulled into the case 42 and the rotating sheet 12 is in a rotatable state.

  Further, the control device 38 is provided with a timer (not shown). When the operation switch 46 is operated, the solenoid 36 is energized for a predetermined time by the timer, and the rotating sheet 12 is in a rotatable state. Has been. On the other hand, when the operation switch 46 is operated and a predetermined time elapses, the solenoid 36 is not energized. That is, the plunger 40 protrudes from the case 42 by the biasing force of the spring.

  For this reason, when the rotating sheet 12 is at a position other than the vehicle travel position Q, the tip of the plunger 40 is in contact with the back surface of the rotary table 32. The sliding resistance is configured to be small in advance.

  Further, when the operation switch 46 is actuated, here, as shown in FIG. 3 (E), the lamp disposed in the operation switch 46 is configured to emit light. On the other hand, when the predetermined time has elapsed, as shown in FIG. 3B, the lamp in the operation switch 46 stops emitting light. That is, the rotating sheet 12 is unlocked when the operation switch 46 is emitting light, and the rotating sheet 12 is locked when the operation switch 46 is not emitting light. Can be visually recognized.

  Incidentally, a shaft 50 is provided in a seat back frame (not shown) that forms the skeleton of the seat back 16 shown in FIG. The seat back 16 is rotatable about the shaft 50 in the vehicle front-rear direction in a state where the rotating seat 12 is disposed at the vehicle travel position Q.

  A gear 52 as an engaged member is fixed to the shaft 50, and a plurality of tooth portions 52A as engaged portions are formed on the gear 52 along the circumferential direction of the gear 52 (seat back). A plurality are formed along the angle θ). Further, one end of a mainspring spring 54 as an urging member is locked to the shaft 50, and the other end of the mainspring spring 54 is locked to the seat back 16 side. By the mainspring spring 54, the seat back 16 is urged forward in the vehicle front-rear direction.

  On the other hand, a rod-like reclining lever 56 as a reclining operation member is provided on the rear side in the vehicle front-rear direction of the seat cushion 14 on the outer side in the vehicle width direction of the seat cushion 14. The reclining lever 56 is disposed along the vehicle width direction in a state where the rotating seat 12 is disposed at the vehicle traveling position Q, and includes a shaft portion 58 provided on the center side of the reclining lever 56. The reclining lever 56 can swing around the shaft portion 58. An engagement portion 60 is provided on the rear side of the shaft portion 58 in the vehicle front-rear direction, and an operation portion 62 is provided on the front side of the shaft portion 58 in the vehicle front-rear direction.

  One end of a torsion spring (not shown) is hooked on the shaft 58, and the other end of the torsion spring is hooked on the operation part 62 or the engaging part 60. The urging force is set to act on 60. Specifically, the urging force acts downward in the vehicle vertical direction at the operation portion 62, and the urging force acts upward in the vehicle vertical direction at the engaging portion 60.

  The engaging portion 60 is provided with an engaging portion 60A that can be engaged (engageable) with a tooth portion 52A of the gear 52 provided on the seat back 16. When the meshing portion 60A is meshed with the tooth portion 52A of the gear 52, the seatback angle θ between the seatback 16 and the seat cushion 14 is set.

  As shown by a two-dot chain line in FIG. 2, when the operation unit 62 is lifted upward in the vehicle vertical direction, the reclining lever 56 swings about the shaft portion 58, and the engaging portion 60 moves downward in the vehicle vertical direction. Moving. That is, the engaging portion 60 moves in a direction away from the gear 52, and the state where the meshing portion 60A is meshed with the gear 52 is released.

  Thus, when the state in which the meshing portion 60A is meshed with the gear 52 is released, the seat back 16 is moved to the vehicle in a state where the rotating seat 12 is disposed at the vehicle travel position Q by the urging force of the mainspring spring 54. It is biased toward the front side in the front-rear direction. As a result, the seat back 16 stands at about 90 degrees (standing position S).

  Further, the operation portion 62 is provided with a bending portion 62A that bends downward in the vehicle vertical direction. When the rotating seat 12 rotates from the vehicle travel position Q shown in FIG. 1 to the vehicle entry / exit position R shown in FIG. 4, as shown in FIG. 3, there is a base on the movement trajectory at the apex 62A1 of the bending portion 62A. A convex portion 28 </ b> A is formed as an interference portion projecting from the member 28.

  That is, the convex portion 28A is set so as to interfere in the process of moving the apex portion 62A1 of the bending portion 62A. The convex portion 28A has a gentle substantially conical shape. When the top portion 62A1 of the curved portion 62A interferes with the convex portion 28A, the top portion 62A1 is guided along the surface of the convex portion 28A. Is set to Thereby, the top portion 62A1 of the curved portion 62A is lifted upward in the vehicle vertical direction so as to get over the top portion 28A1 of the convex portion 28A.

  For example, in the present embodiment, the convex portion 28A is provided at a position rotated about 3 to 7 ° from the position of the top portion 62A1 of the curved portion 62A at the vehicle traveling position Q of the rotating seat 12 to the vehicle getting on / off position R. Yes. The rotation angle varies depending on the dimension of the vehicle 10 in the vehicle width direction. Specifically, in the case of a vehicle having a long dimension in the vehicle width direction, the separation distance from the adjacent seat is increased, so that the top portion 62A1 of the curved portion 62A is convex as compared with a vehicle having a short dimension in the vehicle width direction. The turning angle of the turning sheet 12 until it interferes with the portion 28A may be increased.

(Operation and effect of vehicle rotating seat)
With reference to FIGS. 1, 4 and 5, the operation will be described based on the flowchart shown in FIG.

  In the present embodiment, for example, when an occupant seated on the rotating seat 12 on the driver's seat parks the vehicle 10, in step 100, it is determined whether the shift lever 48 is in the P range or otherwise. Made. In step 100, when the shift lever 48 is outside the P range, as shown in step 102, the lock state of the rotary table 32 is maintained. That is, the solenoid 36 is not energized, and the plunger 40 constituting the solenoid 36 is projected from the case 42 (see FIG. 5C).

  On the other hand, if it is determined in step 100 that the shift lever 48 is in the P range (see FIG. 5D), the process proceeds to step 104. In step 104, the operation switch 46 is in an operable state, and it is determined whether or not the operation switch 46 has been operated. In step 104, when the operation switch 46 is not operated (see FIG. 5B), the locked state of the rotary table 32 is maintained as shown in step 102 (see FIG. 5C).

  If it is determined in step 104 that the operation switch 46 has been operated (see FIG. 5E), the process proceeds to step 106 where the operation switch 46 is activated and the lock state of the rotary table 32 is released. That is, the solenoid 36 is energized, and the plunger 40 is pulled into the case 42 (see FIG. 5F). Thereby, the locked state of the rotary table 32 is released, and the rotating sheet 12 becomes rotatable.

  In this state, as shown in FIG. 4, when the side door 34 is opened and the turning seat 12 is turned, the turning seat 12 moves from the vehicle travel position Q shown in FIG. Rotate to position R. When the rotating seat 12 moves to the vehicle getting on / off position R, the occupant can easily leave the rotating seat 12.

  On the other hand, when the occupant gets on the vehicle, the user sits on the rotating seat 12 at the vehicle getting on / off position R, and in this state, the rotating seat 12 is rotated to the vehicle traveling position Q shown in FIG. When the occupant gets on, the solenoid 36 is not energized, and the plunger 40 constituting the solenoid 36 protrudes from the case 42. That is, the tip of the plunger 40 is in contact with the back surface of the turntable 32.

  For this reason, when the turning seat 12 is turned to the vehicle travel position Q, the plunger 40 is engaged with the hole 32A formed in the turning table 32, so that the turning table 32 is locked. Therefore, the rotating sheet 12 is not rotatable with respect to the base member 28. In this state, the vehicle 10 is ready to travel (see FIG. 5A).

  As described above, in the present embodiment, the rotation seat 12 is rotatable between the vehicle travel position Q shown in FIG. 1 and the vehicle entry / exit position R shown in FIG. That is, when the occupant gets on or off the vehicle 10, the occupant's getting on / off performance is improved by the rotation seat 12 being arranged at the vehicle getting on / off position R.

  Here, in the present embodiment, when the rotating seat 12 is rotated from the vehicle travel position Q to the vehicle entry / exit position R, as shown in FIG. 3, a convex shape is formed on the movement locus of the bending portion 62A of the reclining lever 56. The portion 28A is projected. Therefore, when the rotating seat 12 is rotated from the vehicle travel position Q to the vehicle entry / exit position R, the top portion 62A1 of the curved portion 62A interferes with the convex portion 28A, but as indicated by the two-dot chain line in FIG. When trying to get over the top portion 28A1 of the convex portion 28A, the top portion 62A1 of the curved portion 62A is set to be lifted upward in the vehicle vertical direction.

  As a result, the engaging portion 60 moves downward in the vehicle vertical direction around the shaft portion 58. As a result, the meshing part 60A provided in the engaging part 60 is separated from the tooth part 52A of the gear 52, and the state where the meshing part 60A is meshed with the tooth part 52A is released. When the state where the meshing portion 60A is meshed with the gear 52 is released, the rearward tilt position indicated by the solid line in FIG. The seat back 16 at T is urged toward the front side in the vehicle front-rear direction. As a result, the seat back 16 stands up (standing position S indicated by a two-dot chain line in FIG. 2).

  On the other hand, when the top portion 62A1 of the curved portion 62A gets over the top portion 28A1 of the convex portion 28A, the operation portion 62 is attached to the vehicle in the vertical direction downward as shown by the solid line in FIG. Be forced. At the same time, the engaging part 60 approaches the gear 52 side, the engaging part 60A is engaged with (engaged with) the tooth part 52A, and the seat back angle θ ′ is maintained.

  As described above, according to the present embodiment, the seat back 16 stands up at about 90 degrees when the rotating seat 12 rotates while maintaining good boarding / exiting properties. In this case, it is possible to prevent interference with a seat next to the seat (not shown). In the present embodiment, the seat back 16 is set to stand when the turning seat 12 is turned about 3 to 7 degrees from the vehicle travel position Q toward the vehicle entry / exit position R. In the case of a light vehicle, adjacent seats are closer to each other than a normal vehicle, so it is better to set the seat back 16 to stand up as soon as the rotating seat 12 rotates.

  As described above, in the present embodiment, when the rotating seat 12 rotates, the seat back 16 rises, so that the rotating seat 12 can be simultaneously rotated not only on the driver's seat but also on the passenger seat side. Therefore, it is possible to obtain good boarding / exiting performance not only on the driver's seat side but also on the passenger seat side.

  Further, in the present embodiment, the seat back 16 is raised using the urging force of the mainspring spring 54 acting on the seat back 16, and therefore, it is possible to cope with a lower cost than providing a mechanism for raising the seat back 16 separately. Can do. Further, the seat back 16 can be erected with a simple configuration.

  Further, in the present embodiment, when the rotating seat 12 is rotated from the vehicle travel position Q to the vehicle entry / exit position R, the convex portion 28A is provided on the movement locus of the curved portion 62A of the reclining lever 56, and the curved portion The portion 62A interferes with the convex portion 28A so that the operation portion 62 is lifted upward in the vehicle vertical direction. This is convenient because the seat back 16 stands up automatically when the turning seat 12 is turned.

(Other embodiments)
In this embodiment, as shown in FIGS. 2 and 3, when the rotating seat 12 is rotated from the vehicle travel position Q (see FIG. 1) to the vehicle entry / exit position R (see FIG. 4), the reclining lever 56 The curved portion 62A interferes with the convex portion 28A and is lifted upward in the vehicle vertical direction. However, it is only necessary that the operation portion 62 of the reclining lever 56 is lifted upward in the vehicle vertical direction and the seat back 16 can be raised, and the present invention is not limited to this, and the curved portion 62A and the convex portion 28A are not necessarily required. is not.

  For example, a solenoid (not shown) that interlocks with the operation switch 46 is disposed on the lower side in the vehicle vertical direction of the operation unit 62 in a state where the rotating seat 12 is disposed at the vehicle travel position Q, and the operation switch 46 is activated. Then, it sets so that the plunger of a solenoid may protrude from a case. When the rotating seat 12 is rotated from the vehicle travel position Q (see FIG. 1) to the vehicle entry / exit position R (see FIG. 4), the operation unit 62 gets over the plunger and is pushed upward in the vehicle vertical direction. Like that.

  In this case, the solenoid is set so that the plunger is pulled into the case when the operation switch 46 is actuated and a predetermined time elapses. Then, since the plunger of the solenoid does not protrude at the vehicle entry / exit position R, when the rotating seat 12 is rotated from the vehicle entry / exit position R to the vehicle travel position Q, the operation portion 62 of the reclining lever 56 is located upward in the vehicle vertical direction. Since it is not pushed up to the side, the engaging portion 60 is kept engaged with the gear 52.

  That is, in this case, when the rotating seat 12 rotates from the vehicle travel position Q to the vehicle entry / exit position R, the state where the engaging portion 60 of the reclining lever 56 is engaged with the gear 52 is released. On the other hand, when the rotating seat 12 rotates from the vehicle entry / exit position R to the vehicle travel position Q, the engagement portion 60 of the reclining lever 56 is maintained in the state engaged with the gear 52. Therefore, when the rotating seat 12 is rotated from the vehicle getting on / off position R to the vehicle traveling position Q, the seat back 16 is maintained in the standing state (standing position S).

  Thus, when the rotating seat 12 is rotated from the vehicle getting on / off position R to the vehicle traveling position Q, the seat back 16 may be maintained in the standing state. Such a configuration is not limited to this. For example, although not shown, when the rotating seat 12 is rotated from the vehicle travel position Q to the vehicle entry / exit position R (outward) in the operation unit 62 of the reclining lever 56, the vehicle entrance / exit position R is changed to the vehicle travel position Q. You may make it change the movement locus | trajectory in the operation part 62 of the reclining lever 56 by the time of rotating (return way).

  In this case, for example, the base member 28 is formed with a cam groove constituted by an outward path and a return path, and a convex portion 28A is provided only on the outward path side. The operation unit 62 is configured to rotate about an axis on the engagement unit 60 side, and a torsion spring is provided between the operation unit 62 and the engagement unit 60 side. When the rotating seat 12 is rotated from the vehicle travel position Q to the vehicle entry / exit position R, the operation unit 62 moves in the forward path, and when the rotation seat 12 is rotated from the vehicle entry / exit position R to the vehicle travel position Q, the operation unit 62 is operated. Moves on the return path.

  As described above, the operation unit 62 moves along the cam groove formed by the outward path and the backward path, so that the engaging part 60 is engaged with the gear 52 by interfering with the convex portion 28A in the outward path. Although the state is released, the convex portion 28A does not exist in the return path, so that the engagement portion 60 is kept engaged with the gear 52.

  In the present embodiment, the seat back angle θ can be adjusted by operating the reclining lever 56. However, the seat back angle θ may be adjusted by a driving device such as a motor (not shown). In this case, when the rotating seat 12 rotates from the vehicle travel position Q to the vehicle entry / exit position R, the motor is driven to erect the seat back 16.

  For example, although not shown, a motor is provided in the seat back 16, and a pinion is provided on the shaft portion of the motor. A gear meshing with the pinion is fixed to the shaft of the seat back frame. For example, an operating device is provided on a door trim, and the motor is driven by operating the operating device. When the motor is driven, the pinion rotates and seat backs around the shaft via the gear. Rotate.

  Further, the motor is electrically connected to the control device 38 (see FIG. 6), and how many times the seat back 16 is tilted backward from the standing position S (see FIG. 2) in the vehicle traveling position Q. To be remembered.
