  Next, in order to secure the walk-in space, luggage space, etc. in the vehicle by moving the seat 50 largely forward, as shown in FIG. 8, the seat back 51 of the seat 50 is moved forward and the walk-in is performed. The arm 27 is lowered to press down the front end side of the connecting link 32 of the seat position return memory mechanism 14, and the hook 37 on the rear end side is raised to be detached from the engagement recess 35 of the memory plate 31. As a result, the upper rail 10b is separated from the memory plate 31, and as shown in FIG. 9, the memory plate 31 is tilted backward by the spring structure 36, and the engagement protrusion 31a of the memory plate 31 stops the lower rail 10a. The memory plate 31 is disposed so as to be immovable with respect to the lower rail 10a by engaging with the hole 10e.

  When the walk-in arm 27 is lowered, the rear end side of the lock lever 22 of the slide lock mechanism 13 is simultaneously pressed through the fixing pin 41 of the connecting link 32. As a result, the lock piece 24 is lifted, and the meshing protrusion 24a is detached from the retaining hole 10e of the lower rail 10a to be in an unlocked state. Therefore, the upper rail 10b can move forward with respect to the lower rail 10a in a state where the upper rail 10b is separated from the memory plate 31.

  In this state, when the seat 50 is moved forward to move the upper rail 10b, the slide plate 43 is spanned between the connecting link 32 and at the same time as being separated from the memory plate 31, as shown in FIG. The pulling force of the tension spring 33 is moved rearward with respect to the rising frame 12. As a result, the engagement protrusion 43a provided on the front end side of the slide plate 43 engages with the engagement recess 24b of the rising lock piece 24 to hold the lock piece 24, and the slide lock mechanism 13 is unlocked. Maintained.

  In this state, when the seat is moved to the foremost position, as shown in FIG. 10, the lower end of the release plate 45 that protrudes below the upper rail 10b contacts the release member 47 provided on the lower rail 10a. The slide plate 43 is moved forward with respect to the rising frame 12. Therefore, the engagement protrusion 43a of the slide plate 43 is disengaged from the engagement recess 24b of the lock piece 24, and the tension force of the tension spring 33 between the slide plate 43 and the connecting link 32 increases.

  At this time, when the seat back 51 is in the forward-turned state, the walk-in arm 27 is lowered and the rear end side of the lock lever 22 is kept pressed, so that the lock piece 24 is maintained in the raised state. On the other hand, when the seat back 51 is raised from the forward-turned state, the engagement protrusion 43a of the slide plate 43 is disengaged from the engagement recess 24b of the lock piece 24 as shown in FIG. Is lowered, the engagement protrusion 24a engages with a stop hole 10e provided at the foremost position of the lower rail 10a, the slide lock mechanism 13 is locked, and the seat 50 is fixed at the foremost position. In any case, a walk-in space, a luggage space, and the like are secured in the vehicle.

  In order to return the seat from the foremost position to the original seat position, as shown in FIG. 12, with the seat back 51 in the forward-turned state, the slide lock mechanism 13 is unlocked and the seat is moved backward.

  At this time, when the release plate 45 is detached from the release member 47 of the lower rail 10a, the slide plate 43 is raised again by the tension force of the tension spring 33 between the slide plate 43 and the connecting link 32 as shown in FIG. 12 moves backwards. As a result, the engagement protrusion 43a on the front end side of the slide plate 43 can again be engaged with the engagement recess 24b of the rising lock piece 24 to hold the lock piece 24 in the raised position. Therefore, even if the seat back 51 is raised from the forward-turned state, the lock piece 24 does not descend and the seat can be moved rearward in the standing state.
