The rotation lock plate 43 is a holding member for supporting a lock pin (rotation lock member, see FIG. 15) 44 that locks with the first lock hole 27A and restricts the turning motion of the rotation mechanism. The lock pin 44 is supported by the two surfaces that are in the shape of (1) and are opposed to each other (see FIG. 17). The rotation lock plate 43 is arranged between a lock posture in which the lock pin 44 locks with the first lock hole 27A (see FIG. 15) and a release posture in which the lock pin 44 releases the lock with the first lock hole 27A (see FIG. 16). It can be displaced.

The lock posture and the release posture will be described. The rotation lock plate 43 is always urged to a lock posture by a biasing spring (not shown). When the rotation lock plate 43 is released from the lock posture against the biasing spring and rotated, the stopper is attached to the rotation base 30. The plate 38 is held in the releasing posture.

More specifically, the stopper plate 3
Reference numeral 8 is an arc shape formed concentrically with the inner ring 33, and a second lock hole 38A similar to the lock 27A hole is provided at one end side thereof. During the rotation operation, the lock pin 4 is attached to the outer edge 38B of the stopper plate 38.

When it is turned to the position (turning position), the lock pin 44 is locked with the second lock hole 38A to return to the locked posture, and the turning operation is restricted.
0 is retained.

Next, the slide mechanism will be described. The slide mechanism includes a pair of slide fixing rails 51, which are always arranged along the front and rear direction of the vehicle, on both left and right edges of the slide pedestal 41.
52 (hereinafter, 51 is an outer slide fixing rail, 52 is an inner slide fixing rail) is provided, and a reinforcing plate 53 having a U-shaped cross section is bridged to the front side. Then, both slide fixing rails 51, 52
A pair of slide movable rails 55 and 56 (hereinafter, 55 is an outer slide movable rail and 56 is an inner slide movable rail) are provided corresponding to the above. The front and rear ends of the slide movable rails 55, 56 are bridged by a front connecting plate 57 and a rear connecting plate 58 to form a frame shape as a whole, and the front connecting plate 57 has a tray-shaped footrest 13. Are attached to form the slide movable portion 60. The slide movable portion 60 is provided on the slide fixed rail 5
It is attached to the inside of 1, 52 via balls.

The slide mechanism is provided with a slide lock portion for restricting the slide operation. First, lock brackets (slide receiving members) are provided on the outer surfaces of both slide fixing rails 51 and 52 along the rail length direction.
61 are attached respectively, and the lock bracket 6
1, a plurality of lock holes 62 are provided at a predetermined pitch. On the other hand, lever mounting plates 63 are mounted on the upper surfaces of both slide movable rails 55 and 56, and lock levers 65 and 66 (slide lock members, hereinafter 65 are outer lock levers, and 66 are inner lock levers). ) Are pivotally supported in a posture in which the front and rear directions are opposite to each other.

The lock levers 65 and 66 are composed of a lever portion 67 and a release arm 68 (the release arm of the inner lock lever 66 is 68A and the release arm of the outer lock lever 65 is 68B). A lock claw 67A capable of sequentially engaging with the lock holes 62 is provided at the tip of the portion 67 (see FIGS. 14 and 16). The lock claw 67A disengages / engages with the lock hole 62 in association with the slide operation, and adjusts the slide position.

As described above, the entire slide mechanism is supported by the slide base 41, and the slide base 41 is supported by the outer ring 34 as described above. Therefore, the slide mechanism faces the front-rear direction of the vehicle before the turning operation, but turns with the operation of the rotating mechanism and faces the door opening 3 after the turning operation. Therefore, the passenger seat 10 slides in the front-rear direction of the vehicle to adjust the seat position (indoor sliding) before turning.
After the turning operation, it slides toward the door opening 3 (outdoor slide).

Prior to this turning operation, if the seat position is not at the reference position as described above, it is necessary to move the passenger seat 10 to the reference position by the slide mechanism (preliminary operation), and the positioning means at this time. Are provided across the slide mechanism and the rotation mechanism. First, the inner ring 33 is provided with a stopper member 37 having a contact surface 37A.
Through hole 4 provided on the slide pedestal 41
1B is inserted and it protrudes inside the outer slide movable rail 55 (see FIG. 1). On the other hand, at a position on the inner side of the outer slide movable rail 55 and near the rear end, the outer peripheral surface (contact surface) 72 of the stopper plate 37 contacts the contact surface 37A of the stopper member 37 at the reference position. ) 7
1 is attached (see FIG. 7).

FIG. 12 shows the positional relationship between the stopper member 37 and the meniscus 71 before the turning operation. The stopper member 37 is located in front of the meniscus 71 with respect to the vehicle.
Therefore, before the turning operation, the passenger seat 10 is allowed to slide only from the rear end position (dotted line in the drawing) to the reference position (solid line in the drawing). When the passenger seat 10 at the rear end position is positioned at the reference position, the lock mechanism is simply released and the passenger seat 10 is moved forward along the vehicle, and the stopper member 37 and the meniscus 71 are moved to the reference position. Abut. As a result, the passenger seat 10 is positioned at the reference position.

Now, the outer peripheral surface (contact surface) 72 of the meniscus 71
Has an arc shape concentric with the inner ring 33, and the inner peripheral surface (contact surface) 37A of the stopper member 37 is the contact surface 72.
Since it has an arc shape that matches the above, even if the outer ring 34 is swung at this reference position, both members 3
There is no interference between 7, 71 and the turning movement. The contact surface 72 of the meniscus 71 is set within a predetermined range capable of contacting the contact surface 37A of the stopper member 37 before and after the turning operation. Specifically, the positional relationship between the members 37 and 71 before the turning motion is such that the stopper member 37 and the front region 71A of the meniscus 71 are in contact with each other as shown in FIG. 13, the stopper member 37 and the rear region 71B of the meniscus 71 are in contact with each other. Therefore, after the turning operation, only the sliding operation (outdoor sliding operation) from the reference position to the front end is allowed. Therefore, when the members 3 are slid out of the room and then stored, the two members 3 are held at the reference position.
7, 71 are again in contact with each other.

Next, the operation system of each mechanism will be described. First, the operation system of the slide mechanism, that is, the lock lever 6
The release mechanism of Nos. 5 and 66 will be described. A handle mounting bracket 74 is mounted on the upper surface of the outer slide movable rail 55 on the distal end side, and an operation handle 73 is rotatably engaged therewith via a hinge.

Wires 75 and 76 are attached to the operation handle 73 above and below the hinge. Of these, the lower wire 76 is connected to the release arm 68A of the inner lock lever 66 (see FIG. 16), and the release arm 68A and the release arm 68B of the outer lock lever 65 are connected by another wire 77. (See FIG. 14). Therefore, when the operation handle 73 is rotated clockwise (P direction shown in FIG. 1), the inner lock lever 66 is pulled and rotated by the wire 76, and the outer lock lever 65 is pulled and rotated by the wire 77. Move. As a result, each lock claw 6
7A is disengaged from each lock hole 62.

Next, the operation system of the rotating mechanism, that is, the lock pin 44 releasing mechanism will be described. This lock pin 4
4 is mounted on the slide pedestal 41 side as described above, but its release system is mounted separately on the slide movable portion 60 side. Therefore, the lock can be released only when the passenger seat 10 is at the reference position.

First, the slide pedestal 41 side will be described. A bell link 81 having a substantially triangular shape is rotated via a hinge 84 at a position on the slide pedestal 41 outside the outer slide fixing rail 51 and near the rear end. Installed as possible. One edge portion side of the bell link 81 has an L-shaped connecting arm portion 43A protruding from the edge portion of the rotation lock plate 43 via a rod 83.
It is connected to the. A release pin 82 is provided upright on the other edge of the bell link 81. This release pin 8
By rotating the bell link 81 by pressing 2 in the direction of rotation about the hinge 84, the rotary lock plate 43 rotates via the rod 83 to disengage the lock pin 44 from the first lock hole 27A. It is supposed to do.

A mechanism for pressing the release pin 82 is provided on the slide movable portion 60 side. A release lever 86 is pivotally supported on the rear side mounting plate 89 mounted at the rear end of the outer movable rail 55. The wire connecting portion 86A is provided on one side of the outer edge of the release lever 86.
And a release portion 86B bent downward is also provided. The free end side of the wire 75 is connected to the wire connecting portion 86A, and the release lever 8 is operated by operating the operation handle 73 counterclockwise (in the Q direction shown in FIG. 1).
6 is adapted to rotate. When the handle is operated at the reference position, the release portion 86B comes into contact with the release pin 82 to rotate the bell link 81.

Next, the retainer mechanism for holding the slide mechanism in the locked state during the operation of the rotating mechanism will be described. As shown in FIG. 15, a connection lever 85 is provided inside the inner lock lever 66. This connection lever 85
Are formed of a plate material, and a pair of locking recesses 85 are provided on the outer circumference.
A, 85B and a flange portion 85C are provided. The connection lever 85 is pivotally supported by a square bar 90 (see FIG. 1) attached to the inner side surface of the inner slide movable rail 56, and holds the inner lock lever 66 in a locked state (in the posture shown in FIG. 16). Yes, the posture in which the outer edge of the release arm 68A of the inner lock lever 66 is locked in the locking recess 85A of the connection lever 85) and the inner lock lever 6
6 is openable to allow the opening operation (the attitude shown in FIG. 15, in which the outer edge of the release arm 68A is unlocked from the locking recess 85A).

The connecting lever 85 is always urged to an open position by an urging spring (not shown), but is kept in a holding position by the rotation lock plate 43 during the turning operation. This is because the rotation lock plate 43 and the stopper plate 38 are rotated during the turning operation as described above.
By the action of the lock pin 44, the lock pin 44 is held in the releasing posture (see FIG. 16). Then, when the rotation lock plate 43 is in the release posture, the contact piece 43B attached to the side surface of the rotation lock plate 43 contacts the flange portion 87 of the connection lever 85 and the connection lever 85.
Is held in a holding posture.

Next, the function and effect of the present embodiment configured as described above will be specifically described. When adjusting the seat position of the passenger seat 10 in the room, the operation handle 73 is rotated clockwise (P direction in FIG. 1). As a result, the outer /
Since the inner lock levers 65 and 66 are disengaged from the lock bracket 61, the passenger seat 10 can be slid along the vehicle front-rear direction. Therefore, when the seated person's feet are cramped at the reference position, the passengers' seats can be secured by shifting the position of the passenger seat 10 to the rear of the vehicle.

Next, a procedure for a person with a disability sitting on the passenger seat 10 to transfer to a wheelchair will be described.
First, a passenger first gets out of the vehicle, opens the passenger side door 4, and puts a wheelchair (not shown) on standby outside the door 4. When the seat position of the passenger seat 10 is at a position other than the reference position, the passenger seat 1
A preliminary operation is performed to align 0 with the reference position. To this end, the operation handle 73 is rotated clockwise in the same manner as in the case of adjusting the seat position described above, and the passenger seat 10 is moved forward toward the reference position. Then, when the passenger seat 10 reaches the reference position, the contact surface 72 of the meniscus 71 attached to the outer slide movable rail 55 and the contact surface 37A of the stopper member 37 attached to the inner ring 33 come into contact with each other. The passenger seat 10 is positioned at the reference position.

Then, following the preparatory movement, the turning mechanism makes a turning movement in the vehicle compartment. This time, the operation handle 73 is rotated counterclockwise (Q direction shown in FIG. 1) to rotate the release lever 86 via the wire 75. Then, the release portion 86B of the release lever 86 pushes the release pin 82 of the bell link 81, whereby the bell link 81 rotates. As a result, the rotation lock plate 43 is rotated via the rod 83, and the lock pin 44 of the rotation lock plate 43 and the lock hole 27A of the rotation holding plate 26 are unlocked. Then, when the passenger seat 10 as a whole is manually rotated toward the door opening 3 from this state, the cam groove 25A provided in the cam plate 25 and the cam pin 35 provided in the outer ring 34 act to allow the passenger seat 10 to be seated. Moves forward while turning.

The forward movement associated with the turning operation is performed with the pedestal 21 and the rotary pedestal in a state where the slide mechanism is restrained, that is, the slide fixed rails 51 and 52 and the slide movable rails 55 and 56 are locked. This is an operation performed along the fixed rails 22 and 23 with respect to 30, and is not included in the sliding operation in the present invention. This forward movement operation is performed as an interference avoiding operation for avoiding the front passenger seat 10 from interfering with the center pillar 5 during the turning operation. Therefore, when a sufficient space for allowing the turning motion is ensured in the vehicle compartment, it is not necessary to provide such a mechanism for avoiding interference.

Further, as described above, the sliding operation between the slide fixed rails 51 and 52 and the slide movable rails 55 and 56 is not performed during the turning operation. Since the lock pin 44 moves along the outer edge 38B of the stopper plate 38 during the rotation operation, the rotation lock plate 43 is held in the releasing posture. Then, in this release posture, the contact piece 43B of the rotation lock plate 43 abuts on the flange portion 85C of the connection lever 85 to hold the connection lever 85 in the holding posture. As a result, the locking recess 85A of the connection lever 85 and the release arm 68A of the inner lock lever 66 are locked to hold the slide mechanism in the locked state.

When the turning motion of a predetermined angle is performed,
The lock pin 44 is locked in the second lock hole 38A of the stopper plate 38, and the turning operation is completed. At this time, the passenger seat 10 is in a position facing the door opening 3 as shown in FIG. Then, the lock pin 44 is locked in the second lock hole 38A, whereby the rotation lock plate 43
The release posture of is released. As a result, the abutment piece 43B of the rotation lock plate 43 is connected to the flange portion 8 of the connection lever 85.
Since it is separated from 5C, the holding posture of the connection lever 85 is also released. Therefore, the locking recess 85A of the connection lever 85
The unlocking arm 68A of the inner lock lever 66 is released, and the lock holding of the slide mechanism is released.

Further, the meniscus 71 of the outer slide movable rail 55 is rotated while the abutting surface 72 is slidably contacting the sliding surface 37A of the stopper member 37 in accordance with the turning operation. As a result, the positional relationship between the stopper member 37 and the meniscus 71 is such that the stopper member 37 and the rear region 71B of the meniscus 71 abut and the front region 71A is opened, as shown in FIG. As a result, the passenger seat 10
Is allowed to slide forward, that is, to leave. Upon exiting the operation handle 73 again
Rotate counterclockwise to lock both lock levers 65, 66.
Is disengaged from the lock bracket 62, and the passenger seat 1
0 is passed through the door opening 3 to reach the exit position shown in FIG.

In this exit position, the seat cushion 12
Is projected outside the vehicle so that almost all the seated people are located outside the vehicle. If the wheelchair is arranged so as to be in parallel with the passenger seat 10, the transfer can be smoothly performed. The storing operation from the exit position to the reference position is the reverse of the above-described projecting operation, and thus the duplicated description will be omitted.

As described above, according to the present embodiment, when the passenger's feet are cramped when seated on the passenger seat 10, the passenger's feet are slid rearward so that a wide foot space is always secured. You can do it. Further, the slide mechanism is connected to a rotating mechanism for performing a turning operation, and the entire slide mechanism is turned in accordance with the turning operation to change the sliding direction. in this way,
Since a single sliding mechanism can perform sliding operations in two different directions, that is, an indoor sliding operation and an outdoor sliding operation, compared to the case where a dedicated sliding mechanism is provided for each sliding direction,
It is possible to reduce the number of parts forming the passenger seat 10.

Further, the positioning when moving the passenger seat 10 to the reference position prior to the turning operation in the projecting operation is performed by simply sliding the passenger seat 10 toward the reference position, the stopper member 37 and the meniscus. 71 abuts at the reference position to automatically position the passenger seat 10. Therefore, the operability is excellent as compared with the case where the positioning is performed with the marking or the like as a target. Then, the positioning means at the time of the storing operation, that is, the passenger seat 1 after the protruding operation
Positioning means for returning 0 from the exit position to the reference position is shared by the positioning means for adjusting the passenger seat 10 to the reference position prior to the above-mentioned projecting operation, that is, the stopper member 37 and the meniscus 71. The number of parts forming the seat 10 can be reduced.

A release mechanism for releasing the lock of the rotation mechanism is separately attached to the seat cushion 12 side, and is connected to the rotation lock plate 43 via the bell link 81 only when the passenger seat 10 is at the reference position. In conjunction with this, the lock pin 44 is unlocked from the first lock hole 27A. Therefore, even if the release operation is performed at a position other than the reference position, the lock pin 44 is not interlocked with and the lock is not released. Therefore, it is possible to avoid a malfunction such as a turning operation performed at a position other than the reference position, and it is possible to smoothly perform the exit / storing operation. Further, during the turning operation, the rotation lock plate 43 restricts the opening operation of the inner lock lever 66 via the connection lever 85. Therefore, it is possible to smoothly perform the projecting operation / storing operation without causing an erroneous operation such as the operation of the slide mechanism during the turning operation.
