These are pivotally supported by a rotation shaft 185 so as to be rotatable relative to each other. Since the configuration is the same except that it is formed symmetrically with the forward belt gripping link member 80, the description thereof is omitted.

  The reverse link member 190 includes a substantially L-shaped attachment 191 fixed to the base plate 50, and a reverse link lower member 192 provided on the L attachment 191 so as to be rotatable. Yes. The reverse link member 190 has the same configuration except that the reverse link member 190 is formed symmetrically with respect to the forward belt grip release member 90, and thus the description thereof is omitted.

  As shown in FIG. 6, the reverse regulating member 195 rotates about the rotation shaft 195 b so that the contact portion 195 a can move between a position where the contact portion 195 a contacts the restriction member contact portion 153 and a non-contact position. It is made possible. Specifically, it is formed so as to be rotatable in the vertical direction, and by this rotation, a part of the reverse movement restricting member 195 moves to the restricting member contact portion 153, thereby restricting the movement of the reverse first link member 150. Be regulated so that you can. This reverse regulating member 195 can be released by a separately provided regulating member wire (not shown).

  As shown in FIG. 1, in the slide member moving device 100 manufactured as described above, the power applying unit 20 and the conversion unit 35 can be completely divided, and the conversion unit 35 is divided into the power applying unit 20. It is only necessary that the transmission belt 44 is disposed between the front plate 72 of the belt gripping member 70 and the belt gripping member 73 by moving so as to be inserted from the belt gripping member long hole. These units are fixed by fixing the conversion unit 35 to the upper rail 25 directly or via the sliding member mounting member 10 or the like.

  The slide member moving device 100 manufactured as described above operates as follows. First, the vehicle seat in the seating state is arranged in the state shown in FIG. 11A. In this state, the spring member 41 is wound up by the electric motor 42 and accumulates energy.

  In order to secure a walk-in space on the rear side of the vehicle seat from this state, the seat back is tilted forward. The seat back and the advancement wire 201 are synchronized, and at the same time, the advancement wire 201 is pulled. When the advance wire 201 is pulled, the advance slide member 61 slides backward. Since the second link member for advancing 63 is biased in the counterclockwise rotation direction by the helical spring, the second link member for advancing 63 moves rearward together with the advancing slide member 61 while maintaining the state as it is. Then, the forward grip release part 63b of the second forward link member 63 moves rearward and comes into contact with the forward belt grip release member 90. On the other hand, the first link member for advance 62 is pressed by the first link member abutting portion 63a of the second link member for advance 63 and rotates in the counterclockwise direction. With this rotation, the grip link abutting portion 81 is pressed, and the forward belt grip link member 80 is rotated (becomes the state shown in FIG. 11B). By this rotation, the slide plate 74 is slid forward by the lower advancement grip link member 84 fitted to the slide standing portion 74c of the slide plate 74 below. As a result, the forward belt gripping member 70 grips the transmission belt 44 (the state changes from FIG. 8A to FIG. 8B). Further, the projection 111 a of the central link plate 111 is pressed by the rotation of the first link member 62 for advancement. As a result, the central link member 110 rotates to the right, and the power switching wire 49 is pulled by the pulley member 113 (from the state shown in FIGS. 10A to 10B). Thereby, the power switching link member 48 rotates, the gear member 42a 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, the upper rail 25 and the vehicle seat catch member 10 attached to the upper rail 25 and the vehicle seat gripping member 10 are moved forward with the movement of the transmission belt 44, and the vehicle seat is moved forward. You can move to and secure a walk-in space behind.

  The energy stored in the spring member 41 (see FIG. 4) is released by the movement of the vehicle seat mounting member 10. As a result, the second electric motor switch 45b is turned on by the stopper member 41b of the spring member 41. On the other hand, as shown in FIG. 11A, the forward extension 93 (see FIGS. 5 and 6) of the forward belt grip release member 90 is moved forward by the forward movement member 47a ( 3), the forward release member 92 rotates in the counterclockwise direction. With this rotation, the slide plate 74 of the forward belt gripping member 70 is pressed by the forward extending portion 93 and moves to the original position, that is, rearward. By this movement, the grip of the transmission belt 44 by the forward belt gripping member 70 is released. Further, the advancement second link member 63 is rotated in the clockwise direction as the advancement belt grip releasing member 90 is rotated. As a result, the support of the first link member abutting portion 63a is released, and the first link member for advance 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 opened, and the power switching link member 48 returns to the 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 accumulated. At the same time, the forward slide member 61 returns to the original position.

  On the other hand, on the reverse belt gripping mechanism side, the reverse link member 190 contacts the reverse operation member 47b (see FIG. 3), and the reverse link lower member 192 rotates. As a result, the second reverse link member 160 is rotated in the counterclockwise direction and comes into contact with the reverse seesaw type link member 130. This state is the state of FIG. 12A.

  In this state, when a backward movement lever (not shown) provided in the vicinity of the vehicle seat is operated and the reverse wire 202 is pulled, the reverse second link member 160 is moved to the reverse seesaw type link member 130. Since the reverse link member 190 is fixed to the reverse link member 190, the reverse link member 190 and the reverse reverse seesaw-type link member 130 are used as the axes of the contact portions β of the reverse link member 190 and the reverse reverse link member 130. The reverse seesaw type link member 130 is integrally rotated and rotated in the clockwise direction. With this rotation, the reverse slide member 140 slides forward. As a result, the reverse first link member 150 rotates in the counterclockwise direction, presses the grip link abutting portion 181 to rotate the reverse belt grip link member 180, and slides the slide plate 174 upright. The slide plate 174 is slid rearward by the lower reverse grip link member 184 (see FIG. 7) fitted to the portion 174c. As the slide plate 174 moves, the reverse belt gripping member 170 grips the transmission belt 44. The gripping mechanism is the same as that of the forward belt gripping member 70. In this state, the position of the reverse first link member 150 is restricted when the contact portion 195 a of the reverse restriction member 195 comes out upward and comes into contact with the reverse first link member 150. On the other hand, as shown in FIG. 12, the first link member 150 for reverse rotation causes the central link member 110 to rotate in the counterclockwise direction, and the power switching wire 49 is pulled by the pulley member 113. Thereby, the power switching link member 48 rotates, the gear member 42a 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 reverse transmission belt 44 is gripped, so that the sliding member moving device 100 moves rearward.

  Thus, when the vehicle seat moves rearward and the backrest is raised, the reverse regulating member 195 returns to the 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 above-described embodiments, and can be implemented in various modes as long as they belong to the technical scope of the present invention.

  In the embodiment described above, the transmission belt rotates, but separate belts may be used for the right side and the left side.

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

  As shown in the above-described embodiment, the present invention can be industrially used as a sliding member moving device for attaching a vehicle seat.
