In these drawings, an arrow FR appropriately shown indicates the vehicle front side, an arrow UP indicates the vehicle upper side, and an arrow RH indicates the vehicle right side.

(Configuration of vehicle rotation seat)
First, the configuration of the vehicle turning seat according to the embodiment of the present invention will be described. 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. 2). ) 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 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 rotating sheet 12 is fixed to the rotating table 32, and the rotating sheet 12 can be rotated along the horizontal direction by the rotation of the rotating 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. A stopper (not shown) is provided at the vehicle travel position Q and the vehicle entry / exit position R so that excessive rotation of the turntable 32 is prevented.

  The base member 28 is provided with, for example, a solenoid 36 that constitutes a part of the lock mechanism. In a state where the solenoid 36 is not energized, the plunger 40 constituting the solenoid 36 is pressed by a biasing force of a spring (not shown) in the case 42 and protrudes. 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. 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, when the rotating seat 12 is in the vehicle travel position Q, the solenoid 36 is set not to be energized, and the solenoid 36 is energized when rotating the rotating seat 12. Need to be set to

  For example, in the present embodiment, the solenoid 36 is electrically connected to the control device 38 (see FIG. 4). The control device 38 is electrically connected to a shift lever 48 as a shift member, and a signal indicating the position position of the shift lever 48 is input.

  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.

  The controller 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 activated 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.

(Operation and effect of vehicle rotating seat)
With reference to FIGS. 1-3, an effect | action is demonstrated 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. 3C).

  On the other hand, if it is determined in step 100 that the shift lever 48 is in the P range (see FIG. 3D), 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. 3B), the locked state of the rotary table 32 is maintained as shown in step 102 (see FIG. 3C). That is, whether or not to move the rotating seat 12 to the vehicle getting on / off position R depends on the occupant's will, so when the passenger gets on or off the vehicle 10, the rotating seat 12 is moved to the vehicle getting on / off position R. If it is determined that it is not necessary to arrange the operation switch 46, it is not necessary to operate the operation switch 46.

  If it is determined in step 104 that the operation switch 46 has been operated (see FIG. 3E), 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. 3F).

  In this state, as shown in FIG. 2, 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. 3A).

  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.

  Further, as shown in FIG. 3C, the rotating sheet 12 is prevented from rotating with the plunger 40 of the solenoid 36 engaged with the rotating table 32. It is like that. For this reason, for example, the rotating seat 12 is prevented from rotating during traveling of the vehicle.

  Further, as shown in FIG. 4, an operation switch 46 that can be operated by the occupant and a solenoid 36 are linked via the control device 38, and the operation switch 46 is operated as shown in FIG. Then, the operation switch 46 is activated, and the control device 38 (see FIG. 4) performs control so that the locked state of the rotary table 32 and the rotary seat 12 is released as shown in FIG. 3 (F). Has been.

  That is, the operation switch 46 is activated only after the occupant operates the operation switch 46, and the locked state of the rotating seat 12 is released. Therefore, the rotating seat 12 is prevented from rotating separately from the will of the occupant. be able to. Thus, the convenience can be improved by enabling the rotational movement of the rotational seat 12 based on the will of the occupant. Therefore, according to the present embodiment, it is possible to improve convenience while maintaining the passenger's boarding / exiting ability.

  Further, as shown in FIG. 4, a shift lever 48 is electrically connected to the control device 38. As shown in FIG. 3D, the shift lever 48 is moved to a parking range (hereinafter referred to as “P range”). The operation switch 46 is controlled to be operable as shown in FIG. 3 (E).

  For example, when only the parking brake (not shown) is used, the vehicle 10 shown in FIG. 2 may be movable if the parking brake is not effective. Therefore, the operation switch 46 can be operated only when the shift lever 48 of the vehicle 10 moves to the P range.

  Here, in the present embodiment, the control device 38 (see FIG. 4) controls the operation switch 46 to be operable when the vehicle 10 is parked. That is, when the vehicle 10 is parked, the operation switch 46 is operated by operating the operation switch 46. When the operation switch 46 is actuated, the lock state of the rotating sheet 12 is controlled to be released. That is, even if the operation switch 46 is operated while the vehicle 10 is traveling, the operation switch 46 is controlled so as not to operate. As a result, even if the operation switch 46 is operated by mistake while the vehicle 10 is traveling, the operation switch 46 does not operate, so that the locked state of the rotating seat 12 is not released. That is, the locked state of the rotating sheet 12 is maintained, and the rotating sheet 12 does not rotate.

  In the present embodiment, as shown in FIGS. 3A to 3F, the shift lever 48, the operation switch 46, and the solenoid 36 are respectively shown in FIG. 3 (see FIG. 3) when the vehicle 10 (see FIG. 2) can travel. It is in the state of A) to (C), and in the parking state, it is in the state of FIGS. 3 (D) to (F), respectively.

  Here, in the state of FIG. 3A in which the shift lever 48 is located in the drive range (D range), the rotating sheet 12 does not rotate, and therefore it is essential that the state of FIG. However, in the state of FIG. 3D in which the shift lever 48 is positioned in the P range, the state of FIGS. 3B and 3C in which the operation switch 46 is not operated is obtained. Also good.
