There is provided a seat cushion lock releasing means (not shown) for releasing.

Next, the slide / reclining control mechanism 32 provided on the right base member 21 and the right seat back frame 24 will be described.
A pressing protrusion 34 is fixed to the lower end portion (base end portion) of the right seat back frame 24.
A bracket 35 is fixed to the right side surface of the rear end portion of the right base member 21. As illustrated, the bracket 35 has a first rotation center hole 36, a second rotation center hole 37 positioned obliquely above the first rotation center hole 36, and an arc shape centered on the first rotation center hole 36. An arc hole 38 is formed.
A left end portion of a rotation support pin 39 extending in the left-right direction is fitted and fixed to the first rotation center hole 36 of the bracket 35, and the rotation support pin 39 has a lock holding position shown in FIGS. The walk-in interlocking rotation member 40 that can rotate between the unlocked positions shown in FIG. 7 is rotatably supported. The walk-in interlocking rotating member 40 is a member having a U-shaped cross section, a pressed portion 41 protruding from the upper end of the left plate portion, a connection hole 42 drilled in the lower portion of the right plate portion, and an upper portion of the right plate portion. And a rotation center hole 43 that is rotatably fitted to the rotation support pin 39.
As shown in FIGS. 6 to 9, the connection hole 42 is connected to a rotation connection pin 44 that protrudes at the rear end portion of the slide lever 45 extending in the front-rear direction and extends toward the left side so as to be rotatable around the rotation axis in the left-right direction. The rotation lever 46 that is (fitted) and supported so as to be rotatable about the rotation axis in the left-right direction with respect to the base member 21 is connected to the front end portion of the slide lever 45 so as to be rotatable about the rotation axis in the left-right direction doing. Further, the engagement pin 46 a provided on the rotation lever 46 is engaged with the lock release lever 47 supported so as to be rotatable around the rotation axis in the front-rear direction with respect to the base member 21, and protrudes from the lock release lever 47. A right-facing linkage pin 48 is engaged with an engagement groove 14 a formed in the lock claw 14.
On the rotation support pin 39, a pressed lever 50 (pressed member) positioned between the left side plate portion and the right side plate portion of the walk-in interlocking rotary member 40 is rotatably supported. The pressed lever 50 includes a first support hole 51, a second support hole 52 in which an intermediate portion of the rotation support pin 39 is rotatably fitted, and a rotation located between the first support hole 51 and the second support hole 52. A control groove 53 and a pressed protrusion 56 protruding from the upper end portion are provided. The rotation control groove 53 communicates with a rotation allowance groove 54 extending in an arc direction centering on a rotation support hole 72 of a cancel control lever 70 (described later) and a rear end of the rotation allowance groove 54, and with respect to the rotation allowance groove 54. An inclined arc-shaped rotation restriction groove 55 (not located on the arc centered on the rotation support hole 72) is integrally provided. The pressed lever 50 has an interference position where the pressed projection 56 is positioned on the rotation locus of the pressing projection 34 (the position shown in FIGS. 6 and 7) and a non-interference position where the pressed projection is retracted downward from the rotation locus of the pressing projection 34 (see FIG. 8 and the position of FIG. 9) can be rotated around the rotation support pin 39, and is urged to rotate toward the interference position by the urging force of the urging means (not shown). Further, a cancel operation lever (not shown) linked to the pressed lever 50 is rotatably provided on the right base member 21. When the cancel operation lever is positioned at the non-operation position, the pressed lever 50 is positioned at the interference position by the biasing force of the biasing means. When the cancel operation lever is rotated to the operation position, the pressed lever 50 is moved to the biasing means. Rotates to a non-interference position against the biasing force.

  A rotation support pin 58 is inserted into the first support hole 51 of the pressed lever 50 from the right side, and the vicinity of the left end of the rotation support pin 58 is movably fitted in the arc hole 38 of the bracket 35. A rotation support hole 60 formed in the walk-in operation lever 59 located between the bracket 35 and the pressed lever 50 is rotatably fitted to the rotation support pin 58. A pressed end 61 and a pressing end 62 project from the upper and lower ends of the walk-in operation lever 59, respectively. The walk-in operation lever 59 is located on the same plane (the same left-right direction position) as the left side plate portion of the walk-in interlocking rotation member 40, and the front surface of the pressing end portion 62 is engaged with the rear surface of the pressed portion 41. Yes. Therefore, when the lock claw 14 is located at the lock position, the lock claw urging means (from the lock claw 14, the linkage pin 48, the lock release lever 47, the rotation lever 46, and the slide lever 45) from the lock claw urging means shown in FIGS. The walk-in interlocking rotary member 40 receiving the counterclockwise rotational biasing force is located at the lock holding position and receives the clockwise rotational biasing force of FIGS. 59 is held in the walk-in non-actuated position shown in FIGS. 6, 8, and 9 by a stopper (not shown). On the other hand, when the walk-in operating lever 59 (pressed end portion 61) is rotated counterclockwise against the locking claw urging means, the walk-in operating lever 59 is shown in FIG. Since it rotates to the walk-in operating position (position hidden behind the pressed lever 50) and the pressing end 62 of the walk-in operating lever 59 presses the pressed part 41, the walk-in interlocking rotating member 40 is moved from the lock holding position. Rotates to unlock position. Then, since the slide lever 45, the rotation lever 46, and the lock release lever 47 operate as shown in FIG. 7, the lock claw 14 rotates to the unlock position.

A left end portion of a rotation support pin 64 extending in the left-right direction is fitted and fixed to the second rotation center hole 37 of the bracket 35. The pressed lever 50 is connected to the rotation support pin 64 via a spacer (not shown), for example. A cancel release lever 65 located on the right side of the shaft is rotatably supported. The cancel release lever 65 includes a pressed protrusion 66 protruding from the upper end, a pressing piece 67 protruding rightward from the front edge, and a rotation support hole 68 formed in the lower part. The cancel release lever 65 is urged to rotate clockwise in FIGS. 6 to 9 by rotation urging means (not shown).
Further, a cancel control lever 70 having an engagement pin insertion hole 71 and a rotation support hole 72 at both ends is located on the right side of the cancel release lever 65, and the rotation support hole 72 is prevented from being removed from the rotation support pin 64. It is fitted in a rotatable state. Further, an engagement pin 73 (engagement protrusion) is fitted into the engagement pin insertion hole 71 from the right side, and the left end portion of the engagement pin 73 is movably fitted in the rotation control groove 53.
The cancel control lever 70 is configured to allow the rotation of the pressed lever 50 around the rotation support pin 39 by fitting the engagement pin 73 into the rotation allowance groove 54 (position shown in FIGS. 6 and 7). By engaging the engaging pin 73 in the rotation restricting groove 55, the lever 50 can be rotated between a rotation restricting position (position in FIG. 8) for restricting the rotation of the pressed lever 50 around the rotation support pin 39. It is urged to rotate toward the rotation restricting position by the urging force of the omitted urging means. Further, as described above, the cancel release lever 65 is urged to rotate clockwise by the rotation urging means. Therefore, when no external force is applied to the cancel release lever 65, the pressing piece 67 is placed on the upper surface of the cancel control lever 70. The cancel release lever 65 abuts and rotates together with the cancel control lever 70. On the other hand, since the pressing piece 67 does not regulate the counterclockwise relative rotation of the cancel release lever 65 with respect to the cancel control lever 70, the cancel release lever 65 can be rotated counterclockwise with respect to the cancel control lever 70. .
The members 34 to 70 described above are components of the slide / reclining control mechanism 32. Further, the pressing protrusion 34, the walk-in interlocking rotation member 40, the slide lever 45, the rotation lever 46, the lock release lever 47, and the walk-in operation lever 59 are components of the “walk-in mechanism”. The pressed lever 50 and the cancel operation lever are components of the “walk-in cancel mechanism”, and the pressing protrusion 34, the pressed lever 50, the cancel release lever 65, the cancel control lever 70, and the engagement pin 73 are “ It is a component of the “cancel release mechanism”.

Next, the operation of the slide / reclining control mechanism 32 (the walk-in mechanism, the walk-in cancel mechanism, and the cancel release mechanism) when the seat back 25 and the seat cushion 30 are rotated will be described.
First, the case where the seat back 25 (seat back frame 24) is located in the upright position and the seat cushion 30 is located in the seatable position as shown in FIGS.
At this time, as shown in FIG. 6, the pressing protrusion 34 does not exert an external force on the walk-in operation lever 59 (the pressed end 61), so that the upper rail 13 is engaged by the lock pawl 14 engaging one of the lock holes 12 a. The sliding with respect to the lower rail 12 is regulated.

Next, the case where the slide / reclining control mechanism 32 (walk-in mechanism) performs a walk-in operation from the state of FIG. 6 will be described.
When the walk-in operating means provided on the seat back 25 is operated to release the reclining lock by the reclining lock means and the seat back 25 is rotated forward by the urging force of the rotation urging means, as shown in FIG. The pressing protrusion 34 presses the walk-in operation lever 59 (the pressed end 61) counterclockwise and rotates it to the walk-in operation position. Then, the pressing projection 34 comes into contact with the front surface of the pressed projection 56, so that the seat back 25 stops rotating at an intermediate inclined position (position in FIGS. 2 and 7) between the standing position and the all-inclined position. When the walk-in operation lever 59 rotates to the walk-in operation position, the lock pawl 14 rotates to the unlock position as described above, and the upper rail 13 (seat 20) can slide with respect to the lower rail 12 (the walk-in operation is performed). Done).
When the seat back 25 is returned from the intermediate inclined position to the standing position side after the upper rail 13 (seat 20) slides to a desired position, the pressing force from the pressing protrusion 34 to the walk-in operation lever 59 (pressed end 61) is increased. Therefore, the lock claw 14 is engaged with the lock hole 12a by the rotation urging force of the lock claw urging means to restrict the sliding of the upper rail 13 with respect to the lower rail 12, and the urging force of the lock claw urging means is further applied. As a result, the walk-in operation lever 59 returns to the walk-in non-operation position.

Next, the operation of rotating the seat back 25 to the fully-down position after the slide / reclining control mechanism 32 (walk-in cancel mechanism) performs the walk-in cancel operation from the state of FIG. 6 will be described.
The cancel operation lever located at the non-operation position is rotated to the operation position, and the pressed lever 50 is rotated to the non-interference position as shown in FIG. The coupling pin 73 is moved to the lower end portion of the rotation restricting groove 55 (the rear end portion of the rotation allowing groove 54).
When the pressed lever 50 is positioned at the non-interference position, the pressing protrusion 34 does not interfere with the pressed lever 50 and the walk-in operation lever 59. Therefore, when the seat cushion 30 is rotated to the retracted position and the walk-in operation means is operated to rotate the seat back 25 to the fully-down position, the walk-in operating lever 59 is positioned at the walk-in non-operating position. Will remain. Therefore, the engagement state of the lock claw 14 and the lock hole 12a is not released, and the slide restriction of the upper rail 13 with respect to the lower rail 12 is maintained (the walk-in operation is canceled by the walk-in cancel mechanism).
Further, when the pressed lever 50 rotates to the non-interference position, the engaging pin 73 relatively moves to the lower end portion of the rotation restricting groove 55 (the rear end portion of the rotation allowance groove 54). The received cancel control lever 70 rotates to the rotation restriction position, so that the engagement pin 73 is fitted to the upper part of the rotation restriction groove 55 (see FIG. 8). Then, since the rotation of the pressed lever 50 around the rotation support pin 39 is restricted by the engagement pin 73 and the rotation restricting groove 55, the pressed lever 50 is held at the non-interference position. Therefore, the occupant can place luggage on the upper surface (rear surface) of the seat back 25.
At this time, the pressing protrusion 34 interferes with the pressed protrusion 66 of the cancel release lever 65 to rotate the cancel release lever 65 counterclockwise relative to the cancel control lever 70 (see the solid line in FIG. 8). The rotational force of the cancel release lever 65 does not reach the cancel control lever 70. Further, when the pressing protrusion 34 moves to the rear of the cancel release lever 65, the cancel release lever 65 returns to the position where the press piece 67 contacts the cancel control lever 70 by the biasing force of the rotation biasing means (FIG. 8). Virtual line reference).

Finally, the case where the slide / reclining control mechanism 32 (cancel canceling mechanism) cancels the walk-in cancel state from the state of FIG. 8 will be described.
When the seat back 25 is rotated to the standing position while the seat cushion 30 is positioned at the retracted position, the pressing protrusion 34 moves to the cancel release lever 65 when the seat back 25 rotates to a position near the intermediate tilt position shown in FIG. Then, the cancel control lever 70 located at the rotation restricting position is rotated to the rotation allowance position via the, and the engagement pin 73 is moved to the lower end portion of the rotation restricting groove 55 (the rear end portion of the rotation allowance groove 54). Then, the pressed lever 50 is rotated counterclockwise by the rotation biasing force of the biasing means, so that the pressed lever 50 is rotated and returned to the interference position while the engagement pin 73 is relatively moved in front of the rotation allowing groove 54. (The cancel cancel mechanism cancels the walk-in cancel state). In addition, as the pressed lever 50 returns to the interference position, the cancel operation lever returns to the non-operation position.
When the seat cushion 25 is returned to the seatable position after the seat back 25 is rotated back to the standing position (or any position on the standing position side from the position near the intermediate tilt position) and reclining locked by the reclining lock means, the seat cushion lock is restored. The means automatically locks the seat cushion 30 and holds the seat cushion 30 in the seatable position. Since the pressed lever 50 has returned to the interference position as described above (because the cancel cancellation mechanism has canceled the cancel state of the walk-in), the seat back 25 is moved forward again (to the intermediate tilt position) after this. If it is defeated, walk-in operation by the walk-in mechanism becomes possible.

As described above, in the present embodiment, the cancel cancellation mechanism operates in conjunction with the rotation of the seat back 25 (since there is no need to rotate the seat cushion 30), the invalid state is set by the action of the walk-in cancellation mechanism. It is easy to return the activated walk-in mechanism to an operable state.
In addition, the press protrusion 34, the pressed lever 50, the cancel release lever 65, the cancel control lever 70, the engagement pin 73, and the cancel operation lever, which are all the components of the walk-in cancel mechanism and the cancel release mechanism, include the base member 21 and the seat. It is provided on the back 25 and is not provided on the seat cushion 30 side. Therefore, even if the attachment position of the seat cushion 30 to the base member 21 is somewhat inaccurate, the walk-in cancel mechanism and the cancel release mechanism can be reliably functioned. In addition, the configuration of the walk-in cancellation mechanism and the cancel cancellation mechanism is simplified as compared with the case where some components of the walk-in cancellation mechanism and the cancellation cancellation mechanism are provided on the seat cushion 30 side.
Further, by rotating the seat back 25 from the fully tilted position to the standing position, the walk-in by the cancel release mechanism (the press protrusion 34, the pressed lever 50, the cancel release lever 65, the cancel control lever 70, and the engagement pin 73) is performed. Therefore, the structure of the sheet 20 and the cancel release operation are simpler than the case where operation means for performing the cancel release operation is separately provided.

Next, a second embodiment of the present invention will be described mainly with reference to FIGS. The same members as those in the first embodiment are designated by the same reference numerals, and detailed description thereof is omitted.
The base member 21 and the seat back frame 24 on the right side of the present embodiment are provided with a slide / reclining control mechanism 74 described below.
A lock claw control mechanism 75 is provided on the right side surface of the right base member 21. The lock claw control mechanism 75 includes a bracket 76 fixed to the base member 21, a power transmission lever 77 that can rotate with respect to the bracket 76, and a torsion spring 81 that urges the power transmission lever 77 to rotate. Yes. The power transmission lever 77 is supported by a bracket 76 so as to be rotatable about its own axis and extends in the front-rear direction, and a pressed end 79 that extends upward while bending from the rear end of the power transmission lever 77. And a power transmission end 80 extending forward while bending from the front end of the power transmission lever 77. A torsion spring 81 provided between the bracket 76 and the power transmission lever 77 rotates the power transmission lever 77 with respect to the bracket 76 so that the linear rotation portion 78 rotates counterclockwise when viewed from the front (front). Energized. The power transmission end 80 is engaged with the lock claw 14 (not shown in FIGS. 10 to 17), and the lock claw 14 is in the locked position when no external force other than the torsion spring 81 is applied to the power transmission lever 77. When the power transmission lever 77 is rotated clockwise as viewed from the front (front) against the urging force of the torsion spring 81, the power transmission end 80 presses the lock claw 14 upward to lock the lock claw. 14 rotates to the unlocked position.

A bracket 83 is fixed to the right side surface of the rear end portion of the right base member 21. A support groove 84 is formed at the front end of the bracket 83, and a spring hooking piece 85 projects from the rear end of the bracket 83. Further, a rotation support hole 86 is formed in the rear portion of the bracket 83.
A left end portion of a rotation support pin 88 extending in the left-right direction is fitted and fixed to the rotation support hole 86 of the bracket 83, and a lock release lever 89 is rotatably supported by the rotation support pin 88. A rotation center hole 90 that is rotatably fitted to the rotation support pin 88 is formed in the front portion of the lock release lever 89, and a stopper 91 located immediately after the rotation center hole 90 is formed on the right side surface of the lock release lever 89. Is protruding. A pressing protrusion 92 extending toward the right side protrudes from the rear portion of the lock release lever 89, and a spring hook piece 93 protrudes from the front end portion of the lock release lever 89. Both ends of the tension spring S1 are engaged between the spring hook 93 of the lock release lever 89 and the spring hook 85 of the bracket 83. The lock release lever 89 can rotate between the lock holding position shown in FIGS. 12, 14, and 15 and the lock release position shown in FIG. 13, and is pulled when no external force is exerted on the lock release lever 89. It is located at the lock holding position by the biasing force of the spring S1. Further, the lower surface of the pressing protrusion 92 of the unlocking lever 89 is always in contact with the upper surface of the pressed end 79.
On the rotation support pin 88, a pressed lever 95 (a pressed member) positioned on the right side of the lock release lever 89 is rotatably supported. The pressed lever 95 includes a rotation center hole 97 that fits rotatably in a state of being secured to the rotation support pin 88, a pressed protrusion 98 that protrudes from the upper end portion, and a spring that protrudes to the right from the rear edge portion. And a hanging piece 99. With respect to the lock release lever 89, the pressed lever 95 has a rear end position where the rear surface of the pressed lever 95 abuts against the front surface of the stopper 91 and can no longer be rotated rearward, and the pressing protrusion 34 separated from the stopper 91 forward. It is possible to rotate around the rotation support pin 88 between the non-interference position (the position shown in FIGS. 14 and 15) retreating downward from the rotation trajectory. As shown in the figure, a coil-shaped portion of a torsion spring S2 (biasing means) is attached to the rotation support pin 88, and both ends of the torsion spring S2 are locked to a spring hook piece 99 and a spring hook piece 93, respectively. This torsion spring S2 urges the pressed lever 95 to rotate toward the rear end position (counterclockwise in FIGS. 12 to 14 and 16) with respect to the lock release lever 89. The rear end position when the pressed lever 95 abuts against the stopper 91 is pressed when the pressed lever 95 does not press the stopper 91 backward (when the lock release lever 89 is positioned at the lock holding position). When the protrusion 98 becomes an interference position (position in FIG. 12) located on the rotation locus of the pressing protrusion 34, and the unlocked lever 89 is positioned at the unlocking position by the pressed lever 95 pressing the stopper 91 backward. Then, it becomes a walk-in operation position (position in FIG. 13) that contacts the stopper 94 that is tilted backward from the interference position and fixed to the right side surface of the base member 21.

A rotation support shaft 100 penetrating the portion in the left-right direction is rotatably supported at the front portion of the right base member 21. A lower end portion of the interlocking lever 101 located on the right side of the base member 21 is fixed to the right end portion of the rotation support shaft 100, and a locking projection 102 is integrally projected on the right side surface of the upper end portion of the interlocking lever 101. It is. On the other hand, a lower end portion of a cancel release lever 103 that is positioned on the left side of the base member 21 and parallel to the interlocking lever 101 is fixed to the left end portion of the rotation support shaft 100. The cancel release lever 103 is longer than the interlocking lever 101, and its upper end always protrudes above the base member 21. Further, both ends of the turnover spring S3 are attached to the right side surfaces of the interlocking lever 101 and the base member 21, respectively. The turnover spring S3 exerts an urging force on the interlock lever 101 and the cancel release lever 103 when the interlock lever 101 and the cancel release lever 103 are located at a neutral position (not shown) orthogonal to the horizontal direction. When the interlock lever 101 and the cancel release lever 103 are located behind the neutral position, the interlock lever 101 and the cancel release lever 103 are urged to rotate toward the cancel release position shown in FIGS. When the lever 101 and the cancel release lever 103 are positioned in front of the neutral position, the interlocking lever 101 and the cancel release lever 103 are urged to rotate toward the walk-in cancel position shown in FIGS.
A linkage ring 104 made of a hard member such as synthetic resin is engaged with the locking projection 102 so as to be relatively movable in the front-rear direction, and both ends of the operation wire W are fixed to the linkage ring 104 and the pressed lever 95, respectively. It is. As shown in the drawing, the portions other than the front and rear end portions of the operation wire W are covered with a flexible covering tube 105, and the front and rear ends of the covering tube 105 are the support groove 84 of the bracket 83 and the right side surface of the base member 21. It is supported by the support groove of the support protrusion 106 protruding from the surface.

As shown in FIGS. 15 and 17, the rotary connecting shaft 23 is rotatably supported by a rotary cam member 108 that is positioned on the left side of the right base member 21 and has a cam groove 109.
A linkage member 111 is fixed to the left side surface of the seat back frame 24, and the linkage member 111 and the rotating cam member 108 are rotatably connected via a rotation connecting pin 112 extending in the left-right direction.
Furthermore, a substantially V-shaped V-shaped lever 114 is rotatably supported on the left side surface of the right-side base member 21 via a rotation support pin 113. A cam pin 115 protruding from the upper end of the V-shaped lever 114 is movably fitted in the cam groove 109.
Further, the rear end portion of the slide lever 117 extending in the front-rear direction is rotatably connected to the lower end portion of the V-shaped lever 114 via the rotation connection pin 116 extending in the left-right direction. A front end portion of the slide lever 117 is rotatably connected to a lower end portion of the cancel release lever 103 via a rotation connection pin 118 extending in the left-right direction.

  The pressing protrusion 34, the tension spring S1, the torsion spring S2, the turnover spring S3, the operation wire W, and the reference numerals 75 to 118 described above are components of the slide / reclining control mechanism 74. Further, the pressing protrusion 34, the lock claw control mechanism 75, the lock release lever 89, the pressed lever 95, the tension spring S1, and the torsion spring S2 are components of the “walk-in mechanism”. Further, the pressed lever 95, the rotation support shaft 100, the interlocking lever 101 (locking protrusion 102), the cancel release lever 103, and the operation wire W are components of the “walk-in cancel mechanism”, and the rotation cam member 108 is linked. The member 111, the rotation connection pin 112, the rotation support pin 113, the V-shaped lever 114 (cam pin 115), the rotation connection pin 116, the slide lever 117, the rotation connection pin 118, and the torsion spring S2 are constituent elements of the “cancel release mechanism”. It is.

Next, the operation of the slide / reclining control mechanism 74 (the walk-in mechanism, the walk-in cancel mechanism, and the cancel release mechanism) when the seat back 25 and the seat cushion 30 are rotated will be described.
First, as shown in FIG. 12, the case where the seat back 25 (seat back frame 24) is located in the upright position and the seat cushion 30 is located in the seatable position will be described.
At this time, as shown in FIG. 12, the pressing protrusion 34 does not exert an external force on the pressed lever 95 (pressed protrusion 98), so the pressed lever 95 is held at the interference position by the torsion spring S2. Further, since no external force is applied from the pressed lever 95 to the lock release lever 89, the lock release lever 89 is positioned at the lock holding position by the urging force of the tension spring S1. Further, since no force is applied to the pressed end 79 from the lock release lever 89, the lock pawl 14 is held in the locked position, and the sliding of the upper rail 13 with respect to the lower rail 12 is restricted.

Next, a case where the slide / reclining control mechanism 74 (walk-in mechanism) performs a walk-in operation from the state of FIG. 12 will be described.
When the seat back 25 is rotated forward by the urging force of the rotation urging means by operating the walk-in operation means provided on the seat back 25, the pressing projection 34 is moved to the pressed lever 95 (covered) as shown in FIG. Since the pressing protrusion 98) is pressed rearward to rotate to the walk-in operation position where the pressed lever 95 abuts against the stopper 94, the seat back 25 stops rotating at the intermediate inclined position (position in FIG. 13). When the pressed lever 95 further rotates to the walk-in operation position, the pressed lever 95 presses the stopper 91 rearward, so that the lock release lever 89 rotates to the lock release position. Therefore, as shown in FIG. 89 pressing protrusions 92 rotate the pressed end 79 downward. As a result, the power transmission lever 77 rotates in the clockwise direction when viewed from the front (front) against the urging force of the torsion spring 81, and the lock claw 14 pressed upward by the power transmission end 80 is in the unlock position. Since it rotates and escapes from the lock hole 12a, the upper rail 13 becomes slidable with respect to the lower rail 12 (walk-in operation is performed).
Note that when the pressed lever 95 rotates to the walk-in operation position, the operation wire W is pulled backward from the state of FIG. 12, and therefore the linkage ring 104 is also pulled backward. However, since the interlocking lever 101 and the cancel release lever 103 are positioned at the cancel release position in FIG. 12, the linkage ring 104 only moves backward (i.e., idles) with respect to the locking projection 102. The cancel release lever 103 remains in the cancel release position.
When the seat back 25 is returned from the intermediate inclined position to the standing position side after the upper rail 13 (seat 20) slides to a desired position, the pressing force from the pressing protrusion 34 to the pressed lever 95 (pressed protrusion 98) is released. Therefore, the unlocking lever 89 returns to the lock holding position by the urging force of the tension spring S1, and the pressed lever 95 pressed by the stopper 91 returns to the interference position. Further, when the lock release lever 89 is returned to the lock holding position, the lock claw control mechanism 75 returns to the state shown in FIG. 12, and the lock claw 14 is rotated to the lock position by the lock claw urging means, and the lock hole 12a is moved. Engage.

Next, after performing the walk-in cancel operation by the slide / reclining control mechanism 74 (walk-in cancel mechanism) from the state shown in FIG. 12, the operation of rotating the seat back 25 to the fully-down position, and the slide / reclining control mechanism 74 ( The operation in which the cancellation cancellation mechanism) cancels the walk-in cancellation state will be described.
In this case, first, the seat cushion 30 is rotated to the retracted position, and the cancel release lever 103 covered with the seat cushion 30 is exposed. Then, the cancel release lever 103 (and the interlocking lever 101) located at the cancel release position is rotated to the walk-in cancel position (see FIGS. 14 and 15). Then, as shown in FIG. 14, the linkage ring 104 and the operation wire W are pulled forward by the locking projection 102, so that the pressed lever 95 located at the interference position rotates to the non-interference position. When the pressed lever 95 rotates to the non-interference position, no rotational force is applied from the pressed lever 95 to the lock release lever 89, and the lock release lever 89 remains in the lock holding position. Holds the engagement relationship with the lock hole 12a while being in the lock position (the walk-in operation is canceled by the walk-in cancel mechanism).
When the pressed lever 95 is positioned at the non-interfering position, the pressing projection 34 does not interfere with the pressed lever 95, so that it is possible to operate the walk-in operating means thereafter to rotate the seat back 25 to the fully tilted position. (See FIGS. 16 and 17). Then, as shown in FIG. 17, the cam pin 115 is pushed rearward and upward by the front end face of the cam groove 109 of the rotating cam member 108, so that the V-shaped lever 114 rotates counterclockwise from the position of FIG. 15 slides backward from the position of FIG. 15, and the interlocking lever 101 and the cancel release lever 103 that have been located at the walk-in cancel position are rotated and returned to the cancel release position by the backward movement force of the slide lever 117 (see FIG. 17). ). Then, the locking projection 102 relatively moves backward (misses) to the rear end portion of the linkage ring 104 in the linkage ring 104, so that the forward pulling force that has been exerted from the locking projection 102 to the linkage ring 104 and the operation wire W. Is released. As a result, the pressed lever 95 located at the non-interference position is rotated to the interference position by the rotational biasing force of the torsion spring S2 (the cancel cancellation mechanism cancels the walk-in cancel state (not shown)).

Finally, a case where the sheet apparatus 10 is returned to the state shown in FIG. 12 from the state shown in FIGS. 16 and 17 will be described.
When the seat back 25, which has been located at the fully collapsed position with the seat cushion 30 positioned at the retracted position, is rotated backward (not shown), the pressed lever 95 (pressed protrusion 98) positioned at the interference position is pressed. The protrusion 34 abuts from the rear, and the seat back 25 rotates to the standing position side while rotating the pressed lever 95 to the non-interference position side. Further, when the pressing protrusion 34 gets over the pressed lever 95 (pressed protrusion 98) forward and the pressing force against the pressed lever 95 disappears from the pressing protrusion 34, the pressed lever 95 is interfered by the rotational biasing force of the torsion spring S2. Rotate back to position (returns to walk-in cancel state).
When the seat back 30 is returned to the seating position after the seat back 25 is rotated and returned to the standing position (or the standing position side from the position near the intermediate inclined position) and reclining locked by the reclining lock means, the seat cushion locking means is moved to the seatable position. The cushion 30 is automatically locked to hold the seat cushion 30 in the seatable position. As described above, since the pressed lever 95 has returned to the interference position at this time (because the cancel release mechanism has canceled the cancel state of the walk-in), the seat back 25 is again moved forward (intermediate tilt position). If you defeat it, you can walk-in with the walk-in mechanism.

As described above, this embodiment also includes all the components of the walk-in cancel mechanism and the cancel release mechanism, the pressed lever 95, the rotation support shaft 100, the interlocking lever 101 (locking protrusion 102), the cancel release lever 103, and the rotation. The cam member 108, the linkage member 111, the rotation support pin 113, the V-shaped lever 114 (cam pin 115), the rotation connection pin 116, the slide lever 117, the rotation connection pin 118, the torsion spring S2, and the operation wire W are connected to the base member 21. It is provided on the seat back 25 and is not provided on the seat cushion 30 side. Therefore, even if the attachment position of the seat cushion 30 to the base member 21 is somewhat inaccurate, the walk-in cancel mechanism and the cancel release mechanism can be reliably functioned. In addition, the configuration of the walk-in cancellation mechanism and the cancel cancellation mechanism is simplified as compared with the case where some components of the walk-in cancellation mechanism and the cancellation cancellation mechanism are provided on the seat cushion 30 side.
Further, by rotating the seat back 25 from the standing position to the fully tilted position, a cancel release mechanism (rotation support shaft 100, interlocking lever 101 (locking projection 102), cancel release lever 103, rotating cam member 108, linkage member 111, Since the walk-in cancel cancellation operation is performed by the rotation support pin 113, the V-shaped lever 114 (cam pin 115), the rotation connection pin 116, the slide lever 117, the rotation connection pin 118, and the torsion spring S2, the cancellation release operation is performed. The structure of the sheet 20 and the cancel releasing operation are simpler than the case where operation means for performing the above is separately provided.
