【Example】

 A preferred embodiment of the present invention will be described below with reference to the accompanying drawings. 1 is a longitudinal sectional view of the one-box wagon, FIG. 2 is a perspective view of the seat, and FIG. 3 is a side view of the same. As shown in FIG. 1, seats 4 and 4 are provided on the floor 2 of the one-box wagon 1 via slide rails 3 ..., and the seat 4 is slightly separated from a door 5 on the side of the vehicle body. As shown in FIGS. 2 and 3, the seat 4 is composed of a seat cushion 7, a seat back 8, armrests 9, 9, and the like.

Supports 10, 10 are fixedly provided on the left and right sides of the seat cushion 7, and a motor M and a control unit 11 for controlling the motor M are arranged in the support 10 as shown in FIG. Set up. A limit switch 12 is provided on the upper surface of the support portion 10, and a lever 13 is provided at the rear portion of the support portion 10, so that the seat back 8 can be reclined by swinging the lever 13. The small-diameter toothed pulley 15 and the large-diameter toothed pulley 16 that rotate by the power of the motor M are connected by a toothed belt 17, and the rotation shaft 18 of the pulley 16 supported on the support portion 10 side. An eccentric gear 19 and a link 20 are fixedly installed in the. An eccentric gear 22 and a link 23 are fixedly mounted on a shaft 21 supported on the support portion 10 side, and an idle gear 25 is provided between the eccentric gear 22 and the eccentric gear 19. The ends of the links 20 and 23 are pivotally attached to the front part of the armrest 9, and the links 20 and 23 are covered with a cover 24. As shown in FIG. 2, the front upper surface of the armrest 9 is provided with two operation levers 26, 27, of which the lever 26 is for moving the armrest 9 to a use position (state A in FIG. 3). The lever 27 is provided to move the armrest 9 to the storage position (state B in FIG. 3). The operating lever 27 is connected via a cable 30 to a crank 29 pivotally attached to the rear portion of the armrest 9, and the rear surface 27a of the operating lever 27 contacts the limit switch 32 when the armrest 9 is in the use position A. The crank 29 is capable of abutting on a lock claw 34 pivotally mounted on the armrest 9, and the lock claw 34 abuts on a limit switch 35 at the use position A of the armrest 9 and engages with a pin 36 provided on the seat back 8. To do.

Next, the operation of the above-mentioned seat will be described. First, when the seat 4 is not used, that is, when the passenger is not sitting on the seat 4, the armrest 9 is in the storage position B. At the storage position B, the upper surface 9a of the armrest 9 is connected to the upper surface 7a of the seat cushion 7 in the same plane as shown in FIG. When the operating lever 26 is pulled from this state in the direction of FIG. 3, the motor M operates to rotate the pulley 15, and this rotation is transmitted to the pulley 16 via the toothed belt 17 and the rotating shaft 18 rotates. The rotation of the rotary shaft 18 causes the link 20 and the eccentric gear 19 to rotate in the clockwise direction in FIG. 3, and the rotation of the eccentric gear 19 is transmitted to the eccentric gear 22 via the idle gear 25 so that the eccentric gear 22 and the link 23 are separated. Rotate clockwise in Fig. 3. Therefore, the links 20 and 23 rotate clockwise, so that the armrest 9 begins to move obliquely upward, that is, in the direction D of FIG. Since the gears 19 and 22 are eccentric gears until the armrest 9 moves from the storage position B to the position E, only the rear end of the armrest 9 is lifted, and thereafter the armrest 9 is entirely moved. . After that, the rear end of the armrest 9 approaches the seat back 8, the lock claw 34 engages with the pin 36, and the lock claw 34 pushes the limit switch 35 to stop the motor M. This state is the use position A of the armrest 9. In this state, when the lever 13 is pulled, the seat back 8 reclines, but at the same time as the lever 13 is operated, the clutch provided in the toothed pulley 15 is disengaged, and the links 20 and 23 can freely rotate. The armrest 9 moves in parallel with the seat back 8, and the armrest 9 can be used even after reclining.

Next, the armrest 9 is moved from the use position A to the storage position B as follows. First, the operation lever 27 is pulled in the C direction in FIG. As a result, the cable 30 is pulled in the F direction in FIG. 3, the lock claw 34 rotates in the G direction, and the lock claw 34 is disengaged from the pin 36. At the same time, the operating lever 27 separates from the limit switch 32, the motor M operates, the links 20 and 23 rotate in the opposite direction (counterclockwise direction), and the armrest 9 moves in the H direction. When the armrest 9 reaches the storage position B, the lower surface of the front portion of the armrest 9 contacts the limit switch 12, the motor M stops, and the armrest 9 stops at the storage position B.

In the above, when the passenger is sitting on the seat 4, the armrest 9 is in the use position A, and when the passenger gets off the vehicle, the armrest 9 moves as described above when the operation lever 27 is pulled. It becomes the storage position B. In this state, as shown in FIG. 1, the upper surface 9a of the arm rest 9 and the upper surface 7a of the seat cushion 7 are flush with each other, so that the upper surface 9a of the arm rest 9 is an extended portion of the seat cushion 7, that is, substantially the seat cushion 7. The passengers can move their hips to the upper surface 9a of the armrest 9 and then get off. Therefore, even if there is a considerable distance from the side end 7b of the seat cushion 7 to the door 5, the passenger can easily get off the vehicle. Similarly, when riding the one-box wagon 1, it is easier to get on if the armrest 9 is in the storage position B, and after the ride, pull the operating lever 26 to move the armrest 9 to the use position A. 9 can be used conventionally.

Although the armrest 9 of this embodiment is moved by operating the operation levers 26 and 27, the present invention is not limited to this, and the movement of the armrest 9 is linked to the opening and closing of the door 5. It may be. For example, when the door 5 is opened, the armrest 9 is moved from the use position A to the storage position B in conjunction with this, and when the passenger gets in and then the door 5 is closed, the armrest 9 is linked to this and the armrest 9 is stored in the storage position B. May be moved to the use position A from. Further, even if the door 5 is closed and the armrest 9 is at the use position A, the armrest 9 may be moved to the storage position B by operating the operation lever 27 while the door 5 is closed. These settings are arbitrary. In this embodiment, a spring-loaded cushioning material is provided at the pivotal support portions of the links 20 and 23 so that excessive force is not applied to the fingers even if they are pinched.

Since the seat device of this embodiment is configured as described above, it has the following effects. First, when the passenger gets on and off, the armrest 9 is in the storage position B, and the upper surface 9a of the armrest 9 is flush with the upper surface 7a of the seat cushion 7. Therefore, the passenger uses the upper surface of the armrest 9 as a part of the seat cushion 7. This makes it easier to get on and off. Further, since the links 20 and 23 support the armrest 9 from below, it is possible to sufficiently support the armrest 9 even if a large load is applied to it. Particularly, in the case of the present embodiment, the rear end of the armrest 9 is also supported by the seat back 8, so that the supporting strength can be further increased. Further, since the armrest 9 moves following the reclining movement of the seatback 8, it is not necessary to remove the armrest 9 from the seatback 8 when reclining the seatback 8, and the armrest 9 can be used as it is after reclining. It's convenient.

FIG. 4 shows another embodiment. In this embodiment, a seat of the present invention is provided in a tandem two-seater passenger car. In the figure, 50 is a windshield, 51 and 51 are left and right doors, and 4 and 4 are the same seats as in the previous embodiment. These seats 4 and 4 are arranged in the front-rear direction of the vehicle body. Even in this passenger car, since the distance between the door 51 and the seat 4 is large, by providing the seat 4 of the present invention, the entry / exitability can be improved.
