One end of a rod 55 is locked to a walk-in plate 57 that is a member that rotates together with the seat back 11 of the reclining mechanism 9, and the other end of the rod 55 is a rotating end above the transmission lever 53. It is locked to the part. Therefore, the transmission lever 53 rotates from the solid line position to the two-dot chain line position in FIG. Further, a groove 61 extending in the direction of the pin 51 is formed on the rotating end side below the transmission lever 53.
[0036]
In the present embodiment, the transmission lever 53 is attached to the transmission lever bracket 71 using a pin 51. The transmission lever bracket 71 has a guide hole (guide means) 77 that extends in the moving direction of the lateral seat track 5 and engages with two guide pins 73 and 75 provided on the upper rail 43 of the lateral seat track 5. The guide portion 71a is formed, and the bent portion 71b is bent from the guide portion 71a in the direction of the floor F and is attached to the transmission lever 53 using the pin 51.
[0037]
By means of the pins 73 and 75 and the guide hole 77, the transmission lever bracket 71 (transmission lever 53) can move only in the moving direction of the lateral seat track 5. Further, the movement range is restricted while the guide pins 73 and 75 are in contact with the end of the guide hole 77.
[0038]

As shown in FIG. 2, the lock open means 101 includes a shaft 103 rotatably provided between the upper rails 23 of the pair of front and rear seat tracks 3, a lock open plate 105 attached to the shaft 103, and a shaft 103. And a pin 107 which is provided on the pin plate 109 and extends in the moving direction of the lateral seat track 5 and can be engaged with and disengaged from the groove 61 of the transmission lever 53.
[0040]
The lock open plate 105 can be brought into contact with an upper bent portion 27b having an arcuate cross section that is bent in the direction of the floor F at the upper portion of the rear end of the lock lever 27.
[0041]
Next, the operation of the above configuration will be described.
The state shown in FIGS. 1 and 2 is a state in which the seat back 11 of the seat body 7 stands and can be seated.
[0042]
Here, when the seat back 11 is tilted forward, the walk-in plate 57 is also rotated, and the movement is transmitted to the transmission lever 53 via the rod 55, and the transmission lever 53 is rotated from the solid line position to the two-dot chain line position.
[0043]
Here, as shown in FIG. 2, when the seat body 7 is positioned on the outer side, the pin 107 of the lock opening means 101 is engaged with the groove 61 of the transmission lever 53, and the movement of the transmission lever 53 Is transmitted to the lock opening means 101 via the pin 107. However, when the seat body 7 is located on the inner side, the transmission lever 53 and the pin 107 of the lock opening means 101 are separated from each other, so that the movement of the transmission lever 53 is not transmitted to the lock opening means 101 (cancellation) )
[0044]
When the seat body 7 is positioned on the outer side, the lock open plate 105 presses the upper bent portion 27b of the lock lever 27 by the rotation of the transmission lever 53, and the lock lever 27 resists the biasing force of a spring (not shown). Thus, the upper rail 23 is movable with respect to the lower rail 21 when the lock hole 31 of the lock lever 27 is detached from the lock teeth 26 of the lower rail 21. Further, due to the urging force of the spring 25, the upper rail 23 (seat body 7) of the front and rear seat track 3 moves to the foremost position, and the walk-in operation is completed.
[0045]
On the other hand, when the seat body 7 is located on the inner side, the movement of the transmission lever 53 is not transmitted to the lock opening means 101 as described above, and therefore the walk-in operation is not performed.
[0046]
At this time, when the seat body 7 is moved toward the outer side, as shown in FIG. 1, the transmission lever 53 is in the position of the two-dot chain line, so that the pin 107 contacts the peripheral edge of the groove 61. When the seat body 7 is further moved to the outer side after the contact, the transmission lever bracket 71 escapes in the direction (inner side) away from the lock opening means 101 against the biasing force of the spring 79, and the seat body 7 is moved to the original position. It can move to the outer side position. When the seat back 11 is returned, the transmission lever 53 returns to the solid line position in FIG. 1, and the groove 61 of the transmission lever 53 is engaged with the pin 107 again by the spring 79.
[0047]
According to the above configuration, the following effects can be obtained.
(1) When the seat back 11 of the seat body 7 is tilted forward, the forward / backward slide lock mechanism is unlocked, the seat body 7 moves forward, and a passage for the passengers to get on and off the rear seat (third seat T) is secured. This makes it easy for passengers in the back seat to get on and off.
[0048]
(2) When the seat body 7 is located on the inner side of the vehicle, a passage for getting on and off the rear seat occupant is secured, so that the rear seat only when the seat body is located on the outer side of the vehicle. It is necessary to secure a passage for the seated person.
[0049]
The unlocking means UR is unnecessary when the seat body 7 that requires a walk-in is located on the outer side of the vehicle and is canceled when the seat body 7 that does not require a walk-in is located on the inner side of the vehicle. The walk-in return work can be eliminated and operability is improved.
[0050]
Further, when the seat body 7 is positioned on the outer side, the seat body 7 is walked in, so that the front seats F, F ′ to the third seat can be moved by moving the seat body 7 to the inner side as in the prior art. The problem that the passage between T is blocked is also eliminated.
[0051]
(3) By using the rod 55 to transmit the forward tilting motion of the seat back 11 to the transmission lever 53, the configuration is simple compared to the case of using a cable with a large variation in pulling allowance and a lot of routing loss. Assembling is also easy.
[0052]
(4) With a simple configuration of the pin 107 and the groove 61 of the transmission lever 53, transmission / transmission cancellation from the transmission lever 53 to the lock opening means 101 can be performed by the position of the seat body 7 (outer side, inner side). it can.
[0053]
The present invention is not limited to the above embodiment. For example, in the above embodiment, the transmission lever 53 is provided with the groove 61 and the lock open means 101 side is provided with the pin 107, but conversely, the transmission lever 53 is provided with a pin and the lock open means 101 side is provided with a groove. It may be provided.
