The stays 15b are mounted so that the seat cushion 9 is horizontal when the seat turn plate 10 is mounted while the seat turn plate 10 is tilted with respect to the horizontal. The length is determined and provided. In the second embodiment, the rotation handle 13
In the same manner as in the first embodiment, the lower plate 11 and the upper plate 12 are rotatable or fixed, and in addition, the slide mechanism 14 is slidable between the guide rail 15 and the adjuster 16, Or, it is in a fixed state. That is, when the rotating handle 13 is positioned below by the urging force, the seat turn plate 10 is in a fixed state, and the guide rail 15 and the adjuster 1
6 is a state where the sheet is fixed so as to be a normal sheet position. On the other hand, in a state where the rotary handle 13 is turned upward against the urging force, the seat turn plate 10 becomes rotatable similarly to the first embodiment, and when the rotary handle 13 is further turned upward, the In the second embodiment, the space between the guide rail 15 and the adjuster 16 is slidable. Other configurations are the same as those of the first embodiment.

The operation of the second embodiment configured as described above will be described. The initial state is the same as in the first embodiment.
An example will be described in which the user is already in a vehicle and goes out of the vehicle body 1. First, the assistant turns the rotary handle 13 upward against the urging force. Then, the lower plate 11
And between the upper plates 12 can be rotated. Then, when the assistant rotates the seat 7 toward the passenger seat door 2, the upper plate 12 rotates and the seat 7 rotates toward the passenger seat door 2. Eventually, the rotation is stopped when it has rotated about 80 degrees. Then, in a state where the rotation is stopped and rotated toward the passenger seat door 2 side, the rotating shaft is provided at the passenger seat door 2 side at about 3 degrees and inclined backward about 5 degrees, so as shown in FIG. The front side of the seat cushion 9 is L1

The slide amount is 105 mm in this embodiment, but may be set as appropriate. For this reason, more seats 7 come out of the vehicle than in the first embodiment. Therefore, getting off can be performed more easily than in the first embodiment. Further, the angle of the slide mechanism 14, which has been attached with an inclination of about 5 degrees, becomes substantially 0 degree by rotating, so that the slide mechanism can be easily slid. After getting off the vehicle, the seat 7 is moved in the rear direction of the seat 7 to slide left and right 15,
15 and the left and right adjusters 16 and 16 are fixed, and the rotating sheet 6 is further fixed to the lower plate 11 and the upper plate 1.
The seat 7 is rotated in the opposite direction until the two are locked, and the seat 7 is positioned in the normal state. At the time of boarding, the seat 7 is rotated in advance in the same manner as described above, the seat is turned on, the seat 7 is rotated in the seated state, the normal state is returned again, and the lower plate 11 and the upper plate 12 are locked. use. In the second embodiment, the rotary handle 13 has a double action. However, the rotary handle 13 may be configured to be capable of rotating the seat turn plate 10 and sliding the slide mechanism 14 in a single action. Handles that enable the rotation of the plate 10 and the sliding of the slide mechanism 14 may be separately provided.

Next, a third embodiment will be described. The third embodiment is similar to the second embodiment in that the rotating seat 6
Can rotate and slide. In the second embodiment, the sliding movement and the rotating movement are performed independently of each other, whereas in the third embodiment, the sliding movement is restricted with the rotating movement. In this embodiment, the sliding motion is performed together with the rotating motion, and when the rotation is completed, the sliding motion is also completed. In the third embodiment, a roller guide and a sheet guide for regulating the movement are added to the second embodiment. That is, 18 is a roller guide. The roller guide 18 includes a guide body 19, left and right reinforcements 20, 20, a reinforcement 20 and a stay 21 for connecting the guide body 19, a left and right reinforcement 20, 20.
The front stay 22 connects the front stays 20 to each other.

The guide body 19 is formed of an L-shaped plate-like body provided along the lower surface of the seat cushion 9, and an L-shaped through hole 19a is formed along the plate-like body. Is established. The width of the elongated hole 19a is set to be equal to or slightly larger than the diameter of a roller described later, and a roller described later is inserted. The reinforcement 20 is made of an L-shaped steel material. As shown in FIGS. 9 and 10, a mounting stay 20 a is fixed to the front and rear of the L-shaped steel material at right angles to the longitudinal direction. , 16, mounting stay 2
0a, and the stay 20 fixes the reinforcement 20 and the guide body 19 together.
At this time, the guide body 19 includes the left and right reinforcements 20,
It is fixed at the approximate center between the two. Furthermore, the front portions of the left and right reinforcements 20 and 20 are connected by a front stay 22. As shown in FIG. 9, the front stay 22 is formed of a plate-like body having a mounting portion erected from the left and right ends in the longitudinal direction, and connects the front ends of the left and right reinforcements 20 by screwing.

The roller guide 18 thus constructed
Is added to a slide mechanism 14 including a guide rail 15 and an adjuster 16 as shown in FIG.
The space between the adjusters 16 is fixed to the left and right adjusters 16, 16, and is fixed to a lower portion of the seat cushion 9. Furthermore, the second
In the same manner as in the first embodiment, it is fixed to the upper plate 12 by the mounting frame 17. 23 is a sheet guide. As shown in FIG. 9, the sheet guide 23 is configured so that the main body 24 formed of a strong plate-like body bent in an L-shape makes the one side of the L-shape upward and horizontal.
Is fixed to the front inner surface of the lower plate 11 and a roller 25 is rotatably mounted on the upper horizontal surface of the main body 24. Roller guide 1 configured in this way
8 and the sheet roller 23 are assembled,
In a normal state, the roller 25 is located in front of the bent portion in the long hole 19a, and when the sheet 7 is rotated, the roller 25 is located behind the long hole 19a.

The rotary handle 13 is connected to the seat turn plate 10 and the slide mechanism 14, and in this embodiment, unlike the second embodiment, the rotary handle 13 is rotated against the urging force to perform a one-action operation. And the lower plate 11 and the upper plate 12 of the seat turn plate 10
It has a function of releasing the locked state in which the two cannot rotate, and releasing the restriction between the guide rail 15 and the adjuster 16 of the slide mechanism 14, which are restricted from moving. Other configurations are the same as those of the second embodiment. The seat turn plate 10 is installed with the rotating surface inclined to the passenger seat door 2 side and the rear side, and the seat cushion 9 is provided with stays having different lengths. By 15b, it is horizontally installed on the seat turn plate 10 in a normal state.

Next, the operation of the third embodiment will be described. As in the description of the operation of the second embodiment, the initial state is a state in which the driver is already in the vehicle and the seat position is the normal state.
First, the rotating handle 13 is turned upward against the urging force, so that the lower plate 11 and the upper plate 12 can be rotated and the slide mechanism 14 can be slid. Next, when the occupant rotates the seat 7 toward the passenger seat door 2, the upper plate 12 rotates and the seat 7 starts rotating toward the passenger seat door 2. At this time, since the roller 25 of the sheet guide 23 fixed to the lower plate 11 is inserted into the long hole 19a of the roller guide 18 fixed to the upper plate 12 side, it is positioned in front of the bent portion in the long hole 19a. The roller guide 18 is regulated by the roller 25 that has been rotated, and the roller 25 moves rearward in the elongated hole 19a with the rotation, and the roller 25 fixed to the lower plate 11, that is, the floor 5 side does not move. The seat 7 moves forward. Since the movement of the seat 7 also involves a rotational movement to be precise, the passenger seat door 2 is rotated while rotating toward the passenger seat door 2 side.
Move to draw a curve forward in the direction. FIG. 11 is a perspective view for explaining a state in which the movement has been completed. As shown in this figure, a footrest 26 may be provided at the lower front part of the seat cushion 9. In the case of the embodiment in which the footrest 26 is attached, it is often the case that an assistant who assists the person who is already sitting on the seat to get on and off the vehicle is necessary. In this case, the assistant can easily rotate the seat 7. The operation handle 27 is attached to the front portion of the passenger seat door 2 side of the footrest 26 as described above. Since the operation handle 27 is located immediately beside the rotation handle 13, the seat 7 can be rotationally moved with the operation handle 27 while operating the rotation handle 13. In this case, it is preferable that the direction of movement against the urging force of the rotary handle 13 be pulled horizontally toward the passenger seat door 2.

The rotation and movement of the seat 7 are shown in FIG.
This will be described based on FIG. The state shown in FIG. 12A is a state before the sheet 7 starts rotating. When the seat 7 is rotatable and slidable and moved by pulling the rotation handle 13 from the state of FIG. 12A, the state shown in FIG. 12B is obtained. That is, the sheet 7 rotates and slides. However, since the roller 25 moves within the bent front portion of the elongated hole 19a of the roller guide 18, the sliding amount with respect to the rotation angle is small. FIG. 12C shows a state in which the rotation is further advanced. FIG.
In the state (c), the seat 7 rotates and slides while the long hole 19 a of the roller guide 18 is guided by the roller 25, so that the occupant's foot does not come into contact with the periphery of the opening 4 of the passenger seat door 2. follow. The passenger's feet do not come into contact with the door trim 2a even when passing through the vicinity of the door trim 2a of the passenger seat door 2, and the bent portion of the elongated hole 19a passes through the roller 25 after passing through the vicinity of the door trim 2a.
Since it moves to the straight portion which is the rear part of 9a, the slide amount with respect to the rotation angle increases and moves. The state where the movement is completed is the state shown in FIG.
After the rotation, the rotation is stopped and the slide is terminated. In a state where the rotation is stopped and the seat 7 is rotated toward the passenger seat door 2, the seat 7 is provided with the rotation axis inclined at approximately 3 degrees toward the passenger seat door 2 and approximately 5 degrees rearward. Similarly to the state shown in FIG. 8, the front side of the seat cushion 9 is lowered by L1 and moves 105 mm toward the passenger seat door 2 and stops. Of course, in the third embodiment, as in the second embodiment, the inclination of the rotation surface of the seat turn plate 10 and the sliding amount by the sliding mechanism 14 may be set as appropriate.

[0023]

Therefore, according to the present invention, the vehicle is stopped with the thighs slightly lowered at the time of getting off, so that it is easy to move on to the next getting-off operation. In addition, since the seat moves to the outside of the vehicle by sliding, getting on and off is easy. Furthermore, the rotation of the slide mechanism that is set so that the front of the vehicle is raised can reduce or eliminate the inclination angle, and the seat can be easily slid. Further, since the rotation and the slide of the seat can be performed simultaneously, the slide can be performed only by the rotation operation, so that the operability is excellent. Further, the inclination angle of the slide mechanism decreases as the rotation is performed, so that the rotation can be smoothly performed.
