  The rotary bearing 8 is arranged on the left side of the swivel lower 7 in the width direction, that is, on the vehicle outer side. By arranging in this way, the rotary bearing is arranged outside the center of the seat body 3 in the width direction, and when the seat body 3 is rotated, the seat body 3 is rotated to push the seat body 3 outward. Can be made.

[Configuration of lifting function]
7-10 is a figure which shows the state which rotated the sheet | seat main body 3 toward the vehicle outward, and lowered | hung it out of the vehicle. 7 is a perspective view of the rotary slide sheet 1, FIG. 8 is a perspective view of the rotary slide mechanism 2, FIG. 9 is a side view of the rotary slide sheet 1, and FIG. 10 is a side view of the rotary slide mechanism 2.

  One end of the arm lower 11 is pivotally connected to the carriage 16, and the multi-end is pivotally connected to the upper end of the seat leg 10 (the portion that supports the backrest of the seat body 3).

  One end of the arm upper 12 is connected to the front end of the carriage 16 so that the end of the arm lower 11 is pivotable. The other end is the upper end of the seat leg 10 and the other end of the arm lower 11 is connected. It is pivotally connected to the front and lower side of the part.

  The guide plate 14 includes a left guide plate 14L and a right guide plate 14R disposed outside the left and right arm uppers 12, and the guide plate 14 is fixed to the swivel upper 9. When the seat body 3 is moved up and down, a roller 13 provided on the outer side surface of the arm upper 12 rolls on the upper surface of the guide plate 14 to guide the arm upper 12.

When the lifting motor 17 is driven while the seat body 3 is in the vehicle, the lifting screw 15 rotates to move the carriage 16 forward. When the carriage 16 moves forward, the arm lower 11 and the arm upper 12 rotate around one end connected to the carriage 16 to push the seat leg 10 forward. Since the arm lower 11 and the arm upper 12 rotate while moving forward, the seat leg 10 descends forward.
As a result, the seat body 3 supported by the seat leg 10 is pushed out of the vehicle and descends to a lower position, so that passengers can easily get on and off.

[Configuration of forward tilt suppression function]
FIG. 11 is a top view of the rotary slide mechanism 2. The guide plate 14 is formed so that the front end portion of the right guide plate 14R is located behind the front end portion of the left guide plate 14L. Further, as shown in the left side view and the right side view of the rotary slide mechanism in FIGS. 4 and 5, the surface of the guide plate 14 facing the forward tilt restraining member 18 is formed in parallel with the upper surface of the forward tilt restraining member 18. The grounding surface 21 is formed. The grounding surface 21L of the left guide plate 14L is formed in front of the grounding surface 21L of the right guide plate 14R.

The forward tilt inhibiting member 18 is fixed to the vehicle body floor together with the floor attachment 4. The forward tilt restraining member 18 is grounded below the grounding surface 21 of the guide plate 14.
The inside of the forward tilt inhibiting member 18 is a cavity, and an electronic device 22 such as an airbag switch is accommodated in the cavity.

[Action]
FIG. 12 is a view showing a state of the rotating slide seat 1 when a forward load is applied to the seat body 3 and the occupant seated on the seat body 3. As shown in FIG. 12, when a load is applied forward, the seat body 3 is inclined forward. Although this inclination can be suppressed by the rotary bearing 8 between the swivel lower 7 and the swivel upper 9, if the inclination is suppressed only by the rotary bearing 8, it is necessary to enlarge the rotary bearing 8, and the rotary slide seat There was a problem that the whole 1 was also enlarged.

Therefore, in the rotating slide sheet 1 according to the first embodiment, the forward tilt suppressing member 18 is provided below the front end portion of the guide plate 14.
FIG. 13 is a diagram illustrating a state of the rotary slide mechanism 2 of the rotary slide sheet 1 when a load is applied forward. As shown in FIG. 13, when the rotary slide mechanism 2 is tilted forward, the ground contact surface 21 of the guide plate 14 is brought into contact with the forward tilt restraining member 18 and the forward tilt of the rotary slide mechanism 2 can be suppressed.

  Therefore, the load that suppresses the forward tilt of the seat body 3 can be shared by the abutment between the guide plate 14 and the forward tilt restraining member 18 and the rotary bearing 8, so that the rotary bearing 8 can be downsized. Thus, it is possible to reduce the size of the rotating slide sheet 1.

Further, there is a possibility that the electronic device 22 disposed below the rotary slide sheet 1 may be damaged due to the forward tilt of the sheet body 3.
Therefore, in the rotating slide sheet 1 of Example 1, the forward tilt suppressing member 18 has a hollow portion, and the electronic device 22 is accommodated in the hollow portion.
Therefore, damage to the electronic device 22 can be prevented even if the seat body 3 is tilted forward.

In addition, the front end portion of the guide plate 14 is positioned in front of the front end portion of the swivel upper 9.
Since the center of gravity of the seat body 3 is the rear portion, the forward tilt of the seat body 3 can be efficiently suppressed by making the front end portion of the guide plate 14 as far forward as possible.

  Further, in order to rotate the seat body 3 to the outside of the vehicle, the rotary bearing 8 is disposed on the vehicle exterior side of the center of the seat body 3 in the width direction. Therefore, if the length of the left guide plate 14L and the length of the right guide plate 14R are the same, the distance between the rotation center of the rotary bearing 8 and the right guide plate 14R increases, and the right guide plate is rotated when the seat body 3 is rotated. The front end of 14R interferes with other parts.

Therefore, in the rotating slide seat 1 of Example 1, the front end of the right guide plate 14R inside the vehicle is formed to be behind the front end of the left guide plate 14L outside the vehicle.
Therefore, when the seat body 3 is rotated, interference between the right guide plate 14R and other parts can be prevented.

  Further, since the seat body 3 of the rotating slide sheet 1 slides in the front-rear direction, the forward tilt restraining member 18 needs to be formed corresponding to the slide amount of the guide plate 14 that moves integrally with the slide of the seat body 3. For this reason, the forward tilt inhibiting member 18 becomes large in the front-rear direction, and there is a possibility that the space under the foot cannot be secured.

Therefore, in the first embodiment, the ground contact surface 21L of the left guide plate 14L is formed in front of the ground contact surface 21L of the right guide plate 14R.
Therefore, when the seat body 3 is slid rearward, the forward tilt of the seat body 3 can be suppressed by the ground contact surface 21L of the left guide plate 14L and the forward tilt restraining member 18, and the seat body 3 slides forward. In this case, the forward tilt of the sheet body 3 can be suppressed by the ground contact surface 21R of the right guide plate 14R and the forward tilt restraining member 18.

  FIG. 14 is a view in which a footrest 23 is provided on the rotary slide seat 1, FIG. 14 (a) is a perspective view, and FIG. 14 (b) is a side view. Since the forward / backward direction of the forward leaning restraining member 18 can be reduced, the forward leaning restraining member 18 can be accommodated within the forward / backward width of the footrest 23 as shown in FIG. it can.

[effect]
The effects of the rotating slide sheet 1 of Example 1 are listed below.

  (1) The swivel lower 7 provided on the vehicle body side, the swivel upper 9 that supports the seat body 3, the seat body 3 can be rotated from the front of the vehicle to the outside of the vehicle with respect to the vehicle body, and the swivel upper 9 is swivel lower 7, a pivot bearing 8 that supports the seat body 7, an arm upper 12 that can raise and lower the seat body 3 in and out of the vehicle, and the arm upper 12 that moves the seat body 3 outside the vehicle. When the seat body 3 is in the vehicle front direction, and the guide plate 14 provided on the swivel upper 9 that supports the arm upper 12 via the roller 13 provided on the side surface of the arm upper 12 And a forward leaning restraining member 18 provided on the lower vehicle body side.

  Therefore, the load that suppresses the forward tilt of the seat body 3 can be shared by the abutment between the guide plate 14 and the forward tilt restraining member 18 and the rotary bearing 8, so that the rotary bearing 8 can be downsized. Thus, it is possible to reduce the size of the rotating slide sheet 1.

(2) The forward tilt inhibiting member 18 has a hollow portion between the vehicle body and the electronic device 22 is accommodated in the hollow portion.
Therefore, damage to the electronic device 22 can be prevented even if the seat body 3 is tilted forward.

(3) The front end of the guide plate 14 extends forward from the front end of the swivel upper 9.
Since the center of gravity of the seat body 3 is the rear portion, the forward tilt of the seat body 3 can be efficiently suppressed by making the front end portion of the guide plate 14 as far forward as possible.

(4) Two guide plates 14 are provided so as to be separated from the seat body 3 in the width direction, the rotation bearing 8 is disposed on the vehicle outer side than the center of the seat body 3 in the width direction, and the right guide on the inner side in the vehicle width direction. The front end of the plate 14R is formed to be behind the front end of the left guide plate 14L on the outer side in the vehicle width direction.
Therefore, when the seat body 3 is rotated, interference between the right guide plate 14R and other parts can be prevented.

(5) Two guide plates 14 are provided to be separated from the seat body 3 in the width direction, and a ground contact surface 21L facing the forward tilt restraining member 18 of the left guide plate 14L, and a forward tilt restraining member of the right guide plate 14R. The position of the ground contact surface 21R facing 18 is different in the front-rear direction.
Since the front-rear direction of the forward tilt inhibiting member 18 can be reduced, a space under the foot can be secured.
