Specifically, it is formed to be rotatable in the vertical direction, and a part of the reverse regulation member 195 is moved to the regulation member abutting portion 153 by this rotation, thereby regulating the movement of the first reverse link member 150. It is regulated to be able to. The reverse travel regulation member 195 can be released by a separately provided regulation member wire (not shown).

  The to-be-slided member moving apparatus 100 produced as mentioned above operate | moves as follows. First, the vehicle seat in the sitting state is disposed in the state shown in FIG. 11A. In this state, the spring member 41 is in a state of being wound up by the electric motor 42 and storing energy.

  From this state, in order to secure a walk-in space on the rear side of the vehicle seat, the seat backrest is folded forward. The seat backrest and the advancing wire 201 are synchronized, and at the same time, the advancing wire 201 is also pulled. When the advancing wire 201 is pulled, the advancing slide member 61 slides rearward. Since the second advancing link member 63 is biased in the left rotation direction by the helical spring by this slide, the second advancing link member 63 moves rearward together with the advancing slide member 61 while maintaining the state as it is. Then, the forward grip release portion 63 b of the forward second link member 63 moves rearward and abuts on the forward belt grip release member 90. On the other hand, the first advancing link member 62 is pressed by the first link member abutting portion 63 a of the second advancing link member 63 and pivots in the left rotation direction. Along with this rotation, the gripping link abutment portion 81 is pressed, and the forward belt gripping link member 80 is pivoted (becomes in the state of FIG. 11B). By this rotation, the slide plate 74 slides toward the front side by the lower advancing gripping link member 84 fitted to the slide standing portion 74c of the slide plate 74 at the lower side. As a result, the advancing belt gripping member 70 grips the transmission belt 44 (the state shown in FIG. 8A to FIG. 8B). Furthermore, the protrusion 111 a of the central link plate 111 is pressed by the rotation of the forward link member 62. As a result, the central link member 110 is rotated to the right, and the power switching wire 49 is pulled by the pulley member 113 (from the state of FIG. 10A to FIG. 10B). As a result, the power switching link member 48 rotates, the gear member 42 a is separated from the spring member 41, and the spring member 41 is opened. Then, the transmission belt 44 is rotated by the force of the spring member 41. Since the forward movement side of the transmission belt 44 is gripped, with the movement of the transmission belt 44, the upper rail 25 and the vehicle seat attachment member 10 attached thereto move forward, and the vehicle seat is forward You can move to the rear to secure a walk-in space.

  The movement of the vehicle seat attachment member 10 releases the stored energy of the spring member 41 (see FIG. 4). As a result, the second electric motor switch 45 b is turned on by the stopper member 41 b of the spring member 41. On the other hand, as shown in FIG. 11A, the forward movement extension part 93 (see FIGS. 5 and 6) of the forward belt grip releasing member 90 is moved forward by the forward movement of the sliding member moving device 100 (see FIGS. 5 and 6). 3), and the forward release member 92 is pivoted in the left rotation direction. Along with this rotation, the slide plate 74 of the advancing belt gripping member 70 is pressed by the advancing extension 93 to move to the original position, that is, to the rear. By this movement, the gripping of the transfer belt 44 by the forward belt gripping member 70 is released. Further, in accordance with the rotation of the advancing belt grip release member 90, the advancing second link member 63 is rotated in the right rotation direction. As a result, the support of the first link member abutment portion 63a is released, and the first advancing link member 62 slides forward by the helical spring 302 and returns to the initial position. By this return, the support of the central link member 110 is released, and the central link member 110 returns to the original position. The power switching wire 49 is released, and the power switching link member 48 returns to its original position. As a result, the first electric motor switch 52a is turned on and the second electric motor switch 45b is also turned on, so that the spring member 41 is wound up again by the electric motor 42 and energy is stored. At the same time, the advancing slide member 61 returns to its original position.

  On the other hand, on the reverse belt gripping mechanism side, the reverse link member 190 abuts on the reverse actuating member 47 b (see FIG. 3), and the reverse link lower member 192 rotates. As a result, the second reverse link member 160 pivots in the left rotation direction, and abuts on the reverse one-shot link member 130. This state is the state of FIG. 12A.

  In this state, when the lever for backward movement (not shown) provided in the vicinity of the vehicle seat is operated and the wire 202 for reverse travel is pulled, the second link member 160 for reverse travel is a seesaw type link member 130 for reverse travel. And the reverse link member 190 is fixed, the second reverse link member 160 and the reverse link member 190 with the contact portion β of the reverse link member 190 and the reverse seesaw type link member 130 as an axis. However, the reverse-use seesaw type link member 130 is integrally rotated in the right rotation direction. Along with this rotation, the reverse slide member 140 slides forward. As a result, the first reverse link member 150 is pivoted in the left rotation direction, and the gripping link abutment portion 181 is pressed to pivot the reverse belt gripping link member 180, and the slide plate 174 is vertically installed at the lower side. The slide plate 174 is slid rearward by the lower reverse gripping link member 184 (see FIG. 7) fitted to the portion 174c. The reverse belt gripping member 170 grips the transmission belt 44 by the movement of the slide plate 174. The mechanism for gripping is the same as the advancing belt gripping member 70. In this state, the position of the first reverse link member 150 is restricted by the contact portion 195a of the reverse regulating member 195 coming out upward and contacting the first reverse link member 150. On the other hand, as shown in FIG. 12, the center link member 110 is rotated in the left rotation direction by the reverse first link member 150, and the power switching wire 49 is pulled by the pulley member 113. As a result, the power switching link member 48 rotates, the gear member 42 a is separated from the spring member 41, and the spring member 41 is opened. As a result, the transmission belt 44 is rotated by the force of the spring member 41, and the transmission belt 44 on the reverse side is gripped, so that the sliding member moving device 100 is moved backward.

  Thus, when the vehicle seat moves rearward and raises the backrest, the reverse movement regulating member 195 returns to its original position, returns to the state shown in FIG. 11A, and again the first electric motor switch 45a and the second electric motor. The motor switch 45b is turned on, and the spring member 41 is wound up. When it is desired to move the vehicle seat forward again, the vehicle seat can be moved repeatedly by performing the same operation.

  The present invention is not limited to the embodiment described above, and may be implemented in various modes within the technical scope of the present invention.

  In the embodiment described above, the transmission belt is rotated, but separate belts may be used for the right and left sides.

  Moreover, although it limited to the vehicle seat as a to-be-slided member, it does not limit to this, Other structural members, such as a slide door, may be sufficient. Moreover, it does not necessarily need to be for vehicles, and may be used for a sliding door etc. for construction.

  As shown in the above-mentioned embodiment, it is industrially applicable as a sliding member moving device for attaching a car seat.
