A protrusion 32a is formed on the right side RH around the seventh pin 29 of the second link 32, and a release lever 38 is placed on the upper side of the protrusion 32a. An eighth pin 30 is erected on the left side LH around the seventh pin 29, and a ninth pin 33 is erected on the end of the left side LH. A protrusion 28 a protruding from the cam 28 is engaged with the upper side UP of the eighth pin 30.

The stopper plate 34 protrudes from the locking lock 36 of the lateral movement device P and does not move. The rod 38 a that pivotally supports the release lever 38 is rotatably supported by the support member 37 a of the laterally movable movable rail 37. The release lever 38 is provided with a tooth 39 that can be engaged and disengaged in a lock hole (not shown) formed in the laterally moving fixed rail 41. The second coil spring 40 biases the rod 38a in a direction in which the tooth 39 is always engaged with a lock hole (not shown) formed in the laterally movable fixed rail 41.

The operation of the embodiment of the present invention having the above configuration will be described next.

In the position where the movable stopper 13 of the right side second sheet D does not collide with the fixed stopper 12, the lateral movement device P is in the position shown in FIGS. That is, the fifth pin 23 is on the rightmost RH of both the first long hole 19a and the second long hole 25 of the cable end 19, and the eighth pin 30 is at the position of the uppermost UP of the fourth long hole 31. . The sixth pin 27 of the first link 21 is at the lowermost end of the third long hole 26, and the protrusion 32a of the second link 32 is also at a stationary position. The tooth 39 is engaged with a lock hole (not shown) formed in the laterally moving fixed rail 41. Therefore, the right side second sheet D is held in a state where it does not move at all in the left-right direction as shown in FIGS. 1 and 2. The sixth pin 27 is stationary while being locked to the cam 28.

When the well-known front and rear slide device for the right second seat D shown in FIGS. 1 and 2 is released and the right second seat D is moved backward to a predetermined position, the movable stopper 13 collides with the fixed stopper 12. When the occupant or the like further moves the right second seat D backward as indicated by the white arrow in FIG. 8, the movable stopper 13 moves to the front side FR of the rail mechanism 14 while the movable stopper 13 collides with the fixed stopper 12. As a result, as shown by the black arrow in FIG. 8, the one end 15a connected to the movable stopper 13 moves to the front FR, and the cable 15 moves to the lower LWR.

Thus, when the cable 15 of the lateral movement device P moves 15 millimeters, the cable end 19 connected to the cable 15 moves to the left side LH as shown in FIGS. The first link 21 rotates counterclockwise as indicated by an arrow in FIG. The sixth pin 27 of the first link 21 rotates the cam 28 counterclockwise as indicated by an arrow in FIG. 15, so that the projection 28 a of the cam 28 pushes down the eighth pin 30, and the second link 32 The 9 pin 33 is also pushed down. Thus, the roller 33a provided on the ninth pin 33 also moves. The protrusion 32a of the second link 32 lifts the release lever 38 and rotates the rod 38a. As shown in FIG. 16, when the tooth 39 is removed from a lock hole (not shown) formed in the laterally movable fixed rail 41, the laterally movable movable rail 37 of the laterally moving device P moves, and the left and right central sides of the automobile The right second sheet D can be moved to the right side. Eventually, the rotation of the second link 32 causes the roller 33a to hit the stopper plate 34 as shown in FIG. 17, and the rotation of the second link 32 is stopped. When the rotation of the second link 32 is stopped, the rotation of the first link 21 and the cam 28 is also stopped.

When the right side second seat D is further moved backward, the cable 15 of the lateral movement device P moves, for example, 25 to 115 millimeters, so that the right side second seat D is located at the center of the automobile, that is, for the right side second seat D, FIG. As shown by the arrow 18, the left side LH can be moved. Then, as shown in FIG. 19, the roller 33 a of the second link 32 that has stopped the rotation of the first link 21 and the cam 28 is detached from the stopper plate 34. Therefore, when the first link 21 further rotates, the cam 28 is also rotated, and the sixth pin 27 of the first link 21 is detached from the cam 28 as shown in FIGS. When the sixth pin 27 is detached from the cam 28, the cam 28 and the first link 21 are returned to the initial position shown in FIG. 9 by a spring (not shown). When the first link 21 returns to the initial position, the second link 32 also returns, so the force that lifted the release lever 38 is released, and the release lever 38 also returns to the original position. However, since the lock hole (not shown) with which the tooth 39 is engaged is not set in the lateral movement fixed rail 41 at that position, the lateral movement device P is held in an unlocked state. If the occupant or the like applies a force further in this direction to move the right side second seat D to the left side LH, the cable 15 is slackened, but the cable 15 is slackened, but the first coil spring 20 is always biased so as to remove slack. . The first coil spring 20 has a function of returning the cable 15 to the original tensioned state when the right second seat D is returned to the original position shown in FIG.

When an occupant or the like slides the right side second seat D to the position of the rearmost RR (referred to as rearmost), the cable 15 is pulled while moving to the rear side RR and the left side LH. Back, in other words, the right second seat D can move to the left side LH and the rear side RR. And since the lock hole (illustration omitted) with which the tooth 39 should mesh | engage in the rear also strike position is set, the front-rear slide is locked and the left-right slide is also locked.

The lateral movement device P is unlocked by the operating force of an occupant or the like that moves the right side second seat D to the rear side RR, and the right side second seat D can be moved to the left and right center side of the vehicle via the lateral movement device P. In addition, the lateral movement device P can be locked at the moving position. Therefore, it is possible to simply move the right side second seat D to the left and right center side of the automobile by the lateral movement device P only by moving the right side seat D to the rear side RR. When the right and left second seat D that has moved to the left and right center side is released from the forward / rearward movement lock and an operating force that moves the right second seat D to the front side FR is applied, the reverse movement of the above explanation results in FIG. It is possible to return to the initial position shown in FIG.

For example, the right side second sheet D and the left side second sheet E are moved closer to each other by the lateral movement device P as shown in FIG. In this case, the right side second seat D and the left side second seat E can be moved to the left and right center positions that do not collide with the wheel houses M and M so as to fill the site Ha 'where the second center sheet C was located. The movement amount for each of the right side second sheet D and the left side second sheet E is half of the lateral width of the site Ha 'where the second center sheet C was located.

Further, the position of the left side second sheet E shown in FIGS. 1 and 2 is left as it is, and as shown in FIG. 4, the right side second sheet D is moved to the entire site Ha ′ where the second center sheet C was located by the lateral movement device P. Move to the left side LH, which is the horizontal direction, so as to fill. In this case, between the right side second seat D and the wheel house M, which is the interior side of the vehicle body, a left and right width passage of all the left and right width dimensions of the ruins Ha 'where the second center seat C was located is formed. Therefore, the right side third seat F which is the rear RR seat of the right side second seat D and the left side second seat E which is the “rear seat” or the rear side RR luggage compartment of the right side second seat D and the left side second seat E which are “rear seats”. In addition, it has an effect that it is easy to enter and exit the left third sheet G. 4, the position of the right side second sheet D is kept at the position shown in FIGS. 1 and 2, and the left side second sheet E is filled with the site Ha ′ where the second center sheet C was located by the lateral movement device P. In this way, it moves to the right side RH, which is the horizontal direction. In this case, a left and right width passage of all the left and right width dimensions of the ruins Ha 'where the second center seat C was located is formed between the left side second seat E and the wheel house M which is the indoor side portion of the vehicle body.

Since the right side second sheet D can be moved to the position shown in FIG. 4, the right side third sheet F, which is a side flip sheet, can be made thicker by the left and right width dimension of the ruins Ha ′ where the second center sheet C was located. Therefore, it can be set as a comfortable seat. There is an effect that the right side second sheet D does not interfere with the right side third sheet F which is the side flip-up sheet. Further, a space for placing a baby carriage or the like can be secured on the floor Ha of the front side FR of the right side second seat D, and an occupant can be seated on the left side second seat E and the left side third seat G. 4, the position of the right side second sheet D is kept at the position shown in FIGS. 1 and 2, and the left side second sheet E is filled with the site Ha ′ where the second center sheet C was located by the lateral movement device P. Thus, it can move to the rear side RR after moving to the right side RH which is the horizontal direction. Accordingly, the left third sheet G, which is a laterally raised sheet, can be thickened by the left-right width dimension of the ruins Ha 'where the second center sheet C was present, and thus can be a comfortable seat. It has the same effect that the left side second sheet E does not interfere with the left side third sheet G that is the side flip-up sheet.

4. Even if the seat back 3 of the right second seat D is tilted to the rear RR as shown in FIG. 5 at the position of the right second seat D shown in FIG. Therefore, an occupant seated in the right second seat D has an effect of being able to sleep. Unlike the case shown in FIG. 5, the left side second seat E is flipped sideward even when the seat back 3 of the left side second seat E is tilted to the rear side RR at a position symmetrical to the right side second seat D shown in FIG. 4. It does not interfere with the left third sheet G. Therefore, an occupant seated on the left second seat E has the same effect of being able to sleep.

As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, A various deformation | transformation is possible.
