The stopper rod 95d is attached and assembled to the tip of the rod that is inserted into the bearing sleeve 95. Thereby, the backlash of the link mechanism 11 and an assembly error can be absorbed. In addition, since the seat leg 4 is set to return to the foremost position before the striker locks 5a and 5b hold the striker S, it is possible to absorb the overstroke associated with the returning operation of the entire seat and damage the link mechanism 11. Can be prevented.

  In the link mechanism 9 described above, the damper 14 is assembled to decelerate the reverse or return operation of the entire seat (see FIG. 3). When the reclining mechanism 6 is unlocked while the entire seat is moved backward, the deceleration damper 14 is biased so that the spiral spring 7 (see FIG. 1) pulls the seat cushion 1 toward the seat back 2. 7, the movement of the seat cushion 1 is decelerated, and it is assembled so as to decelerate moving the entire seat forward.

  As shown in FIGS. 7 and 8, the damper 14 is assembled on the same axis as the rotation support shaft 9a protruding from the cover frame 10b of the link mechanism. The damper 14 includes a cap body 14a formed integrally from a dome portion 140 and an overhanging flange portion 141 protruding to the side of the dome portion 140, and a bottom plate screwed to the dome portion 140 of the cap body 14a from the lower side. It is assembled from a body 14b and a disk body 14c sandwiched and held between the cap body 14a and the bottom plate body 14b.

  The cap body 14a and the bottom plate body 14b are formed of ordinary synthetic resin by providing concentric circular grooves 143 and 144 on the inner surface side. The disc body 14c includes a boss portion 145 into which the knurled shaft of the rotation support shaft 9a is fitted, a shelf plate portion 146 that protrudes from the middle abdominal side of the boss portion 145, and a cap plate 14a and a bottom plate that rise from the shelf plate portion 146. The circular groove 143,144 of the body 14b is provided with concentric fin portions 147, 148 that closely fit with each other, and is formed of a synthetic resin having slipperiness.

  The damper 14 is assembled with viscous oil (not shown) interposed between the circular grooves 143 and 144 of the bottom plate body 14b and the fin portions 147 and 148 of the disk body 14c. In the damper 14, the disk body 14c is a rotation side integrated with the rotation support shaft 9a, and the cap body 14a and the bottom plate body 14b are fixed sides, and the circular grooves 143 and 144 of the cap body 14a and the bottom plate body 14b and the fins of the disk body 14c. Since the parts 147 and 148 are brought into contact with each other through the oil, they are assembled so as to decelerate the rotational speed of the rotation support shaft 9a by the viscous resistance of the oil.

  The damper 14 is assembled so that the start of the rotary shaft 9a and the start of the damper 14 are shifted with time. For this reason, since the arc-shaped concave groove 149 centering on the rotation support shaft 9a is provided on the back surface side of the overhanging flange portion 141, the arc-shaped concave groove 149 is fitted with the stopper pin 10e rising from the cover frame 10b. The cap body 14a, the bottom plate body 14b, and the disk body 14c are combined so as to gradually rotate integrally.

  In addition to the above, a pull pocket 15 for handling is provided in the center in front of the bottom of the seat cushion 1 so as to open downward (see FIG. 1). The pull pocket 15 is provided to store the folded seat body in the recess R of the vehicle body floor F and to lift it from the recess R of the vehicle body floor F.

  A tension strap 16 for unlocking the reclining mechanism 6 is pulled out behind the seat back 2. The tension strap 16 is mainly provided as an element for unlocking the reclining mechanism 6 so as to return the seat back to the seating posture after returning the entire seat to the forward position. An operation lever 17 for unlocking the striker locks 8a and 8b from the striker S is provided behind the seat back 2.

  In the rear seat configured as described above, the operator may perform the following operation from the rear side of the seat when the entire seat is tilted backward from the seating posture and reversed and stored in the recess R of the vehicle body floor F. First, the headrest 3 is pushed down to the upper surface of the seat back 2 and stored in the seat back 2. Next, since the operation lever 17 is pulled, the striker locks 8a and 8b are unlocked from the striker S. At the same time, as shown in FIG. 9 a, the entire seat is moved slightly backward from the seat back 2, and the striker locks 8 a and 8 b are removed from the striker S.

  As the operator moves the entire seat back, the link mechanism 9 starts to move. First, as shown in FIG. 9b, the actuating rod 9c connected to the base bracket 5 (see FIG. 1) pushes the swivel plate 9b (see arrow A), and the swivel plate 9b rotates around the rotation support shaft 9a (see FIG. 9b). (See arrow B).

  As the swivel plate 9b rotates, the first bridging bar 9e connected near the front corner of the swivel plate 9b pushes the connection side of the first swing bar 9d by the support shaft 92b (arrow C). reference). When the first swing bar 9d is pushed by the first bridging bar 9e, the first swing bar 9d swings around the support shaft 92b (see arrow D), and the first swing bar 9d. As a result, the pulling wire 11a of the cable wire 11 is pulled, so that the reclining mechanism 6 is unlocked.

  At the same time, the second bridging bar 9g connected to the swivel plate 9b on the end side opposite to the operating rod 9c is pulled in the direction opposite to the movement of the operating rod 9c (see arrow E). Along with this, the second swing bar 9f moves with the support shaft 93 as a fulcrum, and the guide pin 94 moves along the elongated hole 10d in the direction opposite to the pushing direction of the turning plate 9b by the operating rod 9c (see arrow F). . Since the driven rod 9h is connected to the distal end side of the second swing bar 9f, the driven bar 9h pulls the seat leg 4 (see arrow G), and the seat leg 4 falls to the bottom side of the seat cushion 1. start.

  In the initial state, as shown in FIG. 9 c, the damper 14 is displaced between the stopper pin 10 e of the cover frame 10 b and the concave groove 149 of the overhanging flange 141, so that the deceleration action is not exhibited.

  As described above, when the reclining mechanism 6 is unlocked, the spiral spring 7 is biased in the contracting direction, and the seat cushion 1 is attracted to the seat back 2 by the spiral spring 7 as shown in FIG. Accordingly, as shown in FIG. 10b, the swivel plate 9b is pushed around by the operating rod 9c, so that the seat leg 4 is pushed down by the driven rod 9h. In the damper 14, since the seat cushion 1 is attracted by the spiral spring 7, the recessed groove 149 of the overhanging flange 141 is engaged with the stopper pin 10e of the cover frame 10b as shown in FIG. 10c.

  When the seat cushion 1 is further pulled by the spiral spring 7 as shown in FIG. 11a, the first bridging bar 9e pulls the first swing bar 9d as shown in FIG. 11b (see arrow H). Since the first swing bar 9d pulls the pulling wire 11a of the wire cable 11, the reclining mechanism 6 is locked. While the seat cushion 1 is being pulled, the damper 14 is operated as shown in FIG. 11c, so that the pulling of the seat cushion 1 by the spiral spring 7 is decelerated, so that the seat cushion 1 and the seat back 2 are stable. It is often folded into one.

  Thereafter, since the seat cushion 1 and the seat back 2 are folded and held together by the reclining mechanism 6, the operator places his / her hand on the pull pocket 15 as shown in FIG. What is necessary is just to accommodate in the recessed part R of this. Also at this time, as shown in FIG. 12 b, the damper 14 is operated, so that the entire folded sheet can be stably stored in the recess R of the vehicle body floor F.

  When the entire seat is returned to the seating posture, the operator may hold the pull pocket 15 and take the entire seat out of the storage recess R of the vehicle body floor F as shown in FIG. As the entire seat is taken out, the link mechanism 9 returns as shown in FIG. 13 b, so that the seat leg 4 starts to rise from the bottom side of the seat cushion 1. The damper 14 also returns together with the link mechanism 9 in the idle swing state.

  While the entire sheet is being taken out, the first swing bar 9d swings around the support shaft 90, and the pull wire 11a of the cable wire 11 is pulled by the first swing bar 9d. Is unlocked. However, even when the reclining mechanism 6 is unlocked, the seat cushion 1 and the seat back 2 are folded together by the spiral spring 7, so that the entire seat can be stably taken out from the storage recess R of the vehicle body floor F.

  After that, as shown in FIG. 14a, when the worker takes out the entire seat, the damper 14 starts to operate as shown in FIG. 14b, and the forward moving speed of the entire seat can be reduced. When the entire sheet is taken out and returned, the operating rod 9c pulls the swiveling plate 9b and the driven rod 9h moves so as to push the seat leg 4 contrary to when the entire sheet is stored. 4 can stand up to the bottom side of the seat cushion 1.

  Since the reclining mechanism 6 returns to the locked state, the whole seat is returned until the seat leg 4 is locked to the striker S with the striker locks 8a and 8b while the seat body is folded, and the seat cushion 1 is returned to the seat leg 4 Install on the floor surface of the vehicle body floor F with the lock. Finally, since the strap 16 is pulled, the reclining mechanism 6 may be unlocked and the seat back 2 may be operated to be in the sitting posture.

  By such operations, the entire seat can be stored in the recess R of the vehicle body floor F, so that the reclining mechanism 6 can be unlocked and locked, the entire seat is moved backward, the entire seat is returned and the one-motion is linked with a simple mechanism. Therefore, it is possible to easily perform the redesign work in the vehicle.
