<Embodiment 1>
Below, Embodiment 1 of this invention is demonstrated using FIGS. In the present embodiment, the vehicle seat in the vehicle will be described as an example of the vehicle seat. The directions indicated by appropriate arrows in the drawings are directions that coincide with the front, rear, upper, and lower sides when viewed from the occupant seated on the vehicle seat. Each drawing mainly shows the internal structure of the seat body for easy understanding of the configuration of the embodiment. Therefore, for the seat body, it is illustrated mainly with an internal framework structure such as a frame forming a skeleton, and equipment such as a seat pad and an outer skin mounted on the outside of the frame is omitted or simplified, The description may also be omitted.

  First, the outline of the operation contents of the vehicle seat will be described with reference to FIGS. The vehicle seat is disposed as a rear seat of the vehicle as shown in FIG. A seat body 1 of a vehicle seat includes a seat back 2 as a backrest portion and a seat cushion 3 as a seating portion. The seat body 1 is connected to the seat cushion 3 by recliners 6 (reclining mechanisms) provided at lower portions of both sides in the width direction of the seat back 2. Accordingly, the seat back 2 is configured to be able to adjust the backrest angle with respect to the seat cushion 3 or to be moved forward to the upper side of the seat cushion 3. That is, the seat body 1 can set two positions: a standing state 1A in which the seat back 2 stands with respect to the seat cushion 3; it can. Each recliner 6 is normally held in a locked state in which the backrest angle of the seat back 2 is fixed. Each recliner 6 is configured to rotate the reclining lever (not shown) provided on the seat cushion 3 so that the above-mentioned locked state is released and the backrest angle of the seat back 2 can be adjusted and moved. Yes. Each recliner 6 is connected to the operating parts of the locking mechanism by rod parts (not shown) spanned between the left and right recliners 6, and switching between locking and unlocking is performed synchronously on the left and right. .

  Between the seat body 1 and a vehicle component such as the floor surface F, a slide mechanism 100 is provided that can adjust the seating position in the vehicle front-rear direction with respect to the floor surface F of the seat body 1. The slide mechanism 100 is provided as a pair of left and right between the seat cushion 3 and the floor surface F (vehicle constituent member). The slide mechanism 100 includes an upper rail 102, a lower rail 104, and a slide lock device 120 (slide lock mechanism). The lower rail 104 is formed in a shape extending in the vehicle front-rear direction and disposed on the floor surface F. The upper rails 102 are disposed on the lower surface of the seat cushion 3 on the seat body 1 side, and are fitted to the lower rails 104 so as to be slidable in the rail longitudinal direction. Accordingly, the upper rail 102 can move the seating position of the seat body 1 to an arbitrary position in the vehicle front-rear direction along with the sliding movement. The slide lock device 120 is configured such that the upper rail 102 in the slide mechanism 100 can restrict or release the sliding movement with respect to the lower rail 104. The slide lock device 120 is operated by operating a slide lever (not shown), and simultaneously releases the slide lock state of the upper rail 102 and switches it to a slidable state. The seat body 1 adjusts the seating position to an arbitrary position by sliding the upper rails 102 in the vehicle front-rear direction while the lever operation of the slide lever is performed. When the seat main body 1 stops the lever operation of the slide lever, the slide lock device 120 returns to the slide lock state again and can hold the seat main body 1 in the adjusted seating position.

  A cushion lock device 130 (connection / separation switching mechanism) that enables the seat body 1 to be connected to and separated from the floor surface F side is provided at the lower rear side of the slide mechanism 100. The cushion lock device 130 includes a support bracket 132 that protrudes downward on the rear side of the lower rail 104, and a hook 134 that can rotate on the support bracket 132. The floor surface F is configured with a striker S that engages with the hook 134. The cushion lock device 130 is locked by being pushed and moved in a direction in which the hook 134 and the striker S come into contact with each other by the movement of dropping the seat main body 1 onto the floor surface F, and from there. Therefore, the seat body 1 is held in a locked state so as not to be separated from the floor surface F by the engagement between the striker S and the hook 134. The hook 134 is engaged with the striker S (cushion locked state) can be released by pulling an operation lever L in the operation mechanism 5 described later to the rear side.

  A leg 140 (storage mechanism) that stores the seat main body 1 in a storage position provided on the floor surface F in a separated state of the cushion lock device 130 (connection / separation switching mechanism) is provided at the lower front side of the slide mechanism 100. . The floor surface F (vehicle constituent member) is formed in a stepped shape by a first floor surface F1 and a second floor surface F2 that is recessed downward from the first floor surface F1. In the seat body 1, the back of the seat cushion 3 is supported via a cushion lock device 130, and the front of the seat cushion 3 is supported via a leg 140. Thereby, the seated person seated on the seat body 1 is configured to place the leg on the second floor surface F2. The seating position of the seat body 1 is configured on the second floor surface F2 at the front lower portion with respect to the seat body 1. Here, the leg 140 is a member that spans the front of the lower rail 104 on the first floor surface F1 and the second floor surface F2. One end of the leg 140 is connected to the lower rail 104 so as to be relatively rotatable. Further, the other end of the leg 140 is connected to the second floor surface F2 so as to be rotatable.

  The operation mode of the recliner 6 using the reclining lever and the operation mode of the slide lock device 120 using the slide lever have been described above. The vehicle seat has an operation mode different from the operation mode using the reclining lever and the slide lever. Here, the vehicle seat includes an operation mechanism 5 that can operate the mechanisms of the slide lock device 120, the recliner 6, and the cushion lock device 130 in conjunction with each other. The operation mechanism 5 includes an operation lever L that is disposed below the recliner 6 and hangs downward from the seat cushion 3. An example of the second operation mode is as follows. First, as shown in FIGS. 1 to 3, the operation lever L of the operation mechanism 5 provided in the seat body 1 is operated to release the slide lock state of the slide lock device 120, and the seat body 1 is slid backward. Next, as shown in FIGS. 4 to 6, the operation mechanism 5 releases the locked state of the cushion lock device 130 in a state in which the seat back 2 is shifted to the forwardly tilted state 1 </ b> B that is tilted forward to the upper side of the seat cushion 3. The seat main body 1 in which the cushion lock device 130 is released from the locked state is set to a storage state 1C in which the leg 140 is rotated forward and stored in the second floor surface F2 (storage position). Details of each mechanism will be described below.

  The configuration of the slide mechanism 100 and the slide lock device 120 (slide lock mechanism) will be described with reference to FIG. As illustrated in FIG. 7, the slide mechanism 100 includes a lower rail 104 and an upper rail 102. The lower rail 104 is formed in a U-shaped enclosing cross-section, and is placed in a pair of left and right over the longitudinal direction with the U-shaped opening facing upward. In the lower rail 104, a plurality of through holes 104h penetrating in the plate thickness direction are formed at equal intervals along the longitudinal direction. The upper rail 102 has a flat plate-shaped side surface portion 102a that protrudes from the U-shaped opening of the lower rail 104 and hangs straight with the plate surfaces facing each other. As a result, the upper rail 102 is guided so as to be slidable in the longitudinal direction of the lower rail 104. Further, three through holes 102h penetrating in the plate thickness direction are arranged at equal intervals in the longitudinal direction on the surface portion of the side surface portion 102a near the center in the front-rear direction. Further, on the rear side of the lower rail 104, a hook plate 106 (engagement member) (position detection mechanism) protruding upward from the side surface is provided. The hook plate 106 is provided at a position where it engages with a detection pin 78 (engaged member) of the operation mechanism 5 described later when the hook plate 106 is located at the rearmost position 104z (specific slide position) in the allowable slide range of the seat body 1. It has been.

  A slide lock device 120 having a lock claw 122 that can be inserted into each through hole 102h is disposed at the center of the upper rail 102 where the through holes 102h are arranged and formed. The slide lock device 120 is a device that positions the sheet body 1 at an arbitrary position in the slide movement direction of the slide mechanism 100. Here, the lock claw 122 has three claw shapes that can be inserted into the through holes 102h, and is pivotally connected to the upper rail 102 by a support shaft (not shown). The lock claw 122 is normally biased in the direction in which the claw shape at the tip thereof is inserted into each through hole 102h by the biasing force of a spring member (not shown). Therefore, the lock claw 122 of the slide lock device 120 is brought into a position state where the through hole 102h formed in the upper rail 102 and the through hole 104h formed in the lower rail 104 coincide with each other. The urging force of (omitted) is applied and the through hole 102h and the through hole 104h are penetrated and inserted. Thus, the slide mechanism 100 is held in a slide lock state in which the slide movement of the upper rail 102 is restricted.

  The seat body 1 includes a slide lock cable 29 that transmits an operation force of the rotation operation of the operation mechanism 5 to the slide lock device 120. The slide lock state of the slide lock device 120 is released by a pulling operation of the slide lock cable 29 hooked on the cable hooking portion 122 w provided adjacent to the lock claw 122. The slide lock cable 29 has a double structure in which a linear inner member 29a is inserted into a tube of a tubular outer member 29b. One end of the slide lock cable 29 is hooked on the operation mechanism 5 side as described above. The other end of the slide lock cable 29 is hooked on the slide lock device 120 side. The slide lock cable 29 transmits the operating force of the operating mechanism 5 to the slide lock device 120 side by performing a pulling operation in which the inner member 29a is pulled out from the outer member 29b on one end side of the slide lock cable 29. Is activated. Note that one end of the slide lock cable 29 is held in the initial position state from the slide lock device 120 attached to the other end side of the slide lock cable 29 in the initial state before the operation mechanism 5 is rotated. By being subjected to the action of the holding force, the initial rotation position shown in FIG.

One end of the inner member 29 a is hooked to the cable hooking portion 63 of the slide plate 60. One end of the outer member 29b is hooked on the cushion frame 3f. The other end of the inner member 29 a is hooked to the cable hooking portion 122 w of the lock claw 122 of the slide lock device 120. The other end of the outer member 29b is hooked on the upper rail 102. Accordingly, the slide lock cable 29 is operated by a pulling operation in which the inner member 29a is pulled out from the outer member 29b at one end thereof, whereby the operation force of the operation mechanism 5 is transmitted to the lock claw 122 of the slide lock device 120, and the lock The claw 122 is rotated. The slide plate 60 hooked to one end of the inner member 29a is held in the initial position state from the slide lock device 120 hooked to the other end side of the inner member 29a in the initial state before the rotation operation. By being subjected to the action of the elastic force, it is elastically held in the initial rotational position state shown in FIG.

  The configuration of the cushion lock device 130 (connection / separation switching mechanism) will be described with reference to FIG. As shown in FIG. 7, the cushion lock device 130 includes a support bracket 132 that protrudes downward from the rear side surface of the lower rail 104, a hook 134 that can pivot on the support bracket 132, and elastic rotation of the hook 134. A spring member 136 for biasing is provided. The cushion lock device 130 operates in conjunction with the operation of the operation mechanism 5 so that the connection between the floor surface F (vehicle component) and the seat body 1 can be separated. The seat body 1 includes a cushion lock cable 9 that transmits an operation force of a rotation operation of the operation mechanism 5 to the cushion lock device 130. The cushion lock cable 9 has a double structure in which a linear inner member 9a is inserted into a tubular outer member 9b. One end of the cushion lock cable 9 is hooked on the operation mechanism 5 side as described above. The other end of the cushion lock cable 9 is hooked on the cushion lock device 130 side. The cushion lock cable 9 transmits the operation force of the operation mechanism 5 to the cushion lock device 130 side by performing a pulling operation in which the inner member 9a is pulled out from the outer member 9b on one end side thereof, and the cushion lock device 130 side Is activated. Note that one end of the cushion lock cable 9 is held in the initial position state from the side of the cushion lock device 130 hooked on the other end side of the cushion lock cable 9 in the initial state before the operation mechanism 5 is rotated. By being subjected to the action of the holding force, the initial rotation position shown in FIG.

  The cushion lock cable 9 has a double structure in which a linear inner member 9a is inserted into a tubular outer member 9b. One end of the inner member 9 a is hooked to the cable hooking portion 21 of the lock plate 20. One end of the outer member 9b is hooked on the cushion frame 3f. The other end of the inner member 9 a is hooked to the cable hooking portion 134 w of the hook 134 of the cushion lock device 130. The other end of the outer member 9b is hooked to the support bracket 132. Accordingly, the cushion lock cable 9 is subjected to a pulling operation in which the inner member 9a is pulled out from the outer member 9b at one end thereof, whereby the operation force of the operation mechanism 5 is transmitted to the cushion lock device 130, and the cushion lock device 130 is Operate. The lock plate 20 hooked to one end of the inner member 9a is held in the initial position state from the cushion lock device 130 hooked to the other end side of the inner member 9a in the initial state before the rotation operation. By being subjected to the action of the elastic force, it is elastically held in the initial rotational position state shown in FIG.

  The cushion lock device 130 includes a support bracket 132, a hook 134, and a spring member 136. The support bracket 132 protrudes downward from the rear side surface of the lower rail 104 and is fixed. The support bracket 132 serves as a base that rotatably supports the hook 134. A cable hook 132w for hooking the end of the outer member 9b of the cushion lock cable 9 is formed at the left end of the support bracket 132 in the figure. The cable hook 132w is formed by partially bending the plate shape of the support bracket 132. The hook 134 has a receiving portion 134 a that can receive the striker S, and is pivotally supported by a support shaft 131. On the upper side of the hook 134, a cable hook portion 134w for hooking the end portion of the inner member 9a of the cushion lock cable 9 is formed. The spring member 136 is bridged between the cable hook portion 134w and the support bracket 132. As a result, the hook 134 is normally urged to rotate in the direction in which the receiving portion 134 a receives and engages the striker S by the urging force of the spring member 136. That is, the hook 134 is elastically biased in the clockwise direction in the drawing by the spring member 136.

  In the cushion lock device 130, the end of the inner member 9a hooked on the cable hooking portion 134w is pulled by the operating force of the operating mechanism 5, and the cushion lock cable 9 is pulled in such a manner that it is pulled into the end of the outer member 9b. When operated, the hook 134 rotates counterclockwise in the figure. The hook 134 is in a state where the striker S can be detached from the receiving portion 134a from the hooked state (cushion lock state) with the striker S, and the hooked state with the striker S is released. Thus, the cushion lock device 130 can separate the connection between the floor surface F (vehicle component) and the seat body 1.

  The configuration of the leg 140 (storage mechanism) will be described with reference to FIG. The leg 140 (storage mechanism) is a member that spans the front of the lower rail 104 on the first floor surface F1 and the second floor surface F2, as shown in FIG. One end of the leg 140 is connected to the lower rail 104 so as to be relatively rotatable. Between one end of the leg 140 and the lower rail 104, a first connecting shaft 141 is pivotally supported. The first connecting shaft 141 is elastically biased by a spring member (not shown) toward the leg 140 in the counterclockwise direction (the direction in which the seat body 1 is lifted from the floor surface). This acts as an auxiliary for reducing the weight of lifting the seat body 1 in a state where the cushion lock device 130 is in the separated state. Further, the other end of the leg 140 is connected to the second floor surface F2 so as to be rotatable. The other end of the leg 140 and the second floor surface F2 are pivotally supported as a second connecting shaft 142. Further, the leg 140 is elastically biased to the second connecting shaft 142 by a spring member (not shown) in the clockwise direction in the drawing (the direction in which the seat body 1 is moved away from the second floor surface F2). This acts as an aid for reducing the weight of lifting the seat body 1 when the seat body 1 placed on the second floor surface F2 (storage position) is set to the upright state 1A.

  The configuration of the operation mechanism 5 will be described with reference to FIGS. As shown in FIG. 7, the operation mechanism 5 is assembled to a cushion frame 3 f that forms the skeleton of the seat cushion 3. The operation mechanism 5 is a mechanism that operates the slide lock device 120, the recliner 6, and the cushion lock device 130 in conjunction with each other by pulling the operation lever L backward. .

  As shown in FIG. 8, the recliner 6 is disposed between the plate surfaces between the back frame 2f and the cushion frame 3f forming the skeleton of the seat back 2, and these two are connected to each other. Yes. Here, a spiral ring 2 s is hung between the seat back 2 and the seat cushion 3. The spiral ring 2s is normally urged in the forward rotation direction. The recliner 6 is inserted with a switching shaft 6r for switching the operation state of the reclining lock described above so as to protrude outward from the cushion frame 3f. A release arm 6a is fitted and attached to the projecting end of the switching shaft 6r in the turning direction. The release arm 6a is inserted into the switching shaft 6r and is secured to the switching shaft 6r by mounting a fixing ring 6t from the outer side in the width direction. Thereby, the switching shaft 6r is rotated by the rotation operation of the release arm 6a, and the operating state of both the recliners 6 can be switched. Specifically, the release arm 6a is normally held in the initial position where the tip hangs down by the urging force of a spring member (not shown) assembled to the recliner 6. As shown in FIG. 11, the release arm 6 a is rotated in the clockwise direction in the figure by rotating the operation lever L, thereby rotating the switching shaft 6 r to rotate the reclining lock of each recliner 6. Release the state. Specifically, the rotation operation position of the release arm 6a where the reclining lock state of each recliner 6 is released is the operation position when the operation lever L is rotated to the rotation position shown in FIG.

  The recliner 6 is normally biased in the operating direction that is in the reclining lock state, and is automatically returned to the reclining lock state by stopping the rotation of the switching shaft 6r. Further, the recliner 6 has a lock zone that is returned to the reclining lock state by stopping the rotation of the switching shaft 6r, and a free zone that is not returned to the locked state even if the shaft rotation of the switching shaft 6r is stopped. The former lock zone is usually set in an angular region that is used as a backrest by a passenger seated on the seat body 1. That is, the lock zone includes a rotation position where the seat back 2 is in the standing state 1A (see FIG. 1) in which the seat back 2 stands up with respect to the seat cushion 3 and a rotation position where the seat back 2 is fully retracted. Is set in the area between. The latter free zone is set in an angular region where the passenger is not seated and used. That is, in the free zone, the rotation position where the seat back 2 is in the standing state 1A and the rotation position where the seat back 2 is in the forward tilted state 1B (see FIG. 5) where the seat back 2 is fully tilted forward. Is set in the area between. Therefore, the seat body 1 pivots the switching shaft 6r by a pivoting operation of pulling the operation lever L rearward, releases the reclining lock state of the recliner 6, and moves from the posture of the standing state 1A by urging the spiral spring 2s. When the seat back 2 is tilted forward to shift to the angle region of the free zone of the recliner 6, even if the operating lever L is returned to the original initial position, the posture is in the forward tilted state 1B. As described above, each recliner 6 is in the above-described free zone state when the reclining lock state is released and the seat back 2 is moved forward. Therefore, as shown in FIG. 13, the release arm 6a is returned to and held at the original initial position when the operation of the operation lever L is stopped.

  Further, a rotating bracket 30 that is rotatable with respect to the switching shaft 6r is pivotally supported at the tip of the switching shaft 6r protruding. The rotation bracket 30 is formed in a band plate shape, and a substantially central portion is pivotally supported by the switching shaft 6r so as to extend in the radial direction from the position of the switching shaft 6r. Has an end. One end portion is configured as an engaging portion 32. When the seat back 2 is tilted forward, the engaging portion 32 engages with an L-shaped plate-like spring hanging bracket 2b provided integrally with the back frame 2f. A pin connecting portion 34 is configured at the other end. The pin connecting portion 34 is provided with a connecting pin 38 rotatably attached to one end of a forward fall detection plate 40 (forward fall detection mechanism) formed in a band plate shape. The forward tilt detection plate 40 detects the forward tilt state 1B (see FIG. 1) of the seat back 2 when the engaging portion 32 of the rotating bracket 30 is engaged with the spring hooking bracket 2b, and detects the lock plate 20 described later. It is a member for transmitting. A first slide pin 42 protruding in the thickness direction is formed at the other end of the forward tilt detection plate 40 (upper and lower ends in the drawing in FIG. 11). Further, two engaging portions 36 protruding in a direction orthogonal to the longitudinal direction are formed between the engaging portion 32 of the rotating bracket 30 and the switching shaft 6r, and between the pin connecting portion 34 and the switching shaft 6r. ing. The rotation bracket 30 is regulated to a predetermined rotation angle by the locking portion 36 coming into contact with a stopper 6b fixed to the switching shaft 6r.

  As shown in FIG. 11, an engagement pin 6c is attached to the lower end of the release arm 6a. The engagement pin 6c is inserted and attached to the release arm 6a in the plate thickness direction, and a cylindrical roller 6e is inserted at the inserted end and fixed to a fixing ring (not shown) to prevent the engagement pin 6c from coming off. Has been. Thereby, the roller 6e inserted in the engagement pin 6c is attached to the engagement pin 6c so as to be idled. The roller 6e attached to the engagement pin 6c is provided as a functional component that receives an operation force when a later-described operation lever L is rotated.

  As shown in FIGS. 11 to 13, the cushion frame 3 f is assembled with functional parts for performing the rotation operation of the release arm 6 a described above. Specifically, first, a front-falling stopper 3s for restricting the forward-backward movement of the seat back 2 is formed at a connection portion between the cushion frame 3f and the back frame 2f. As shown in FIG. 12, when the seat back 2 is tilted forward, the front tilt stopper 3s is pressed against an L-shaped plate-like spring-hanging bracket 2b provided integrally with the back frame 2f. The movement of 2 is regulated. In addition, a cable hook portion 3fw for hooking an outer member 9b of a cushion lock cable 9 and an outer member 29b of a slide lock cable 29, which will be described later, is formed at the lower left end of the cushion frame 3f in the figure. ing. The cable hook portion 3fw is formed by partially bending the plate shape of the cushion frame 3f.

  As shown in FIGS. 8 to 13, a lever plate 10 made of an arm-like plate member is pivotally connected to a cushion frame 3 f by a support shaft 8. The support shaft 8 is integrally coupled to the cushion frame 3f, and is in a connected state in which the support shaft 8 is rotatably supported with respect to the lever plate 10. The lever plate 10 is fixed by integrally attaching the end of the arm-shaped operation lever L described above. Thereby, the lever plate 10 is rotated integrally with the operation lever L. As shown in FIG. 8, between the lever plate 10 and the cushion frame 3f, a first winding spring 8s that urges the lever plate 10 to rotate in the clockwise direction is hooked. One end of the first winding spring 8s is fitted and hooked on the head of the support shaft 8 integrated with the cushion frame 3f described above, and the other end is hooked on the lever plate 10 and attached. It has been. As a result, the lever plate 10 is urged to rotate in the clockwise direction in the figure with respect to the cushion frame 3f, and is held in a posture where the operation lever L is suspended by contacting the lever stopper 3fs.

  As shown in FIG. 11, the lever plate 10 is formed with an operation portion 11 that can push and operate the roller 6e mounted on the engagement pin 6c of the release arm 6a described above at the tip of the arm shape. Has been. The operation unit 11 presses the roller 6e to integrally move the release arm 6a when the operation lever L is rotated in the counterclockwise direction shown in the drawing. Accordingly, the operation lever L can release the reclining lock state of each recliner 6 by rotating the release arm 6a in the clockwise direction in the drawing. In addition, the lever plate 10 is formed with a first long hole 15 in which the first slide pin 42 of the forward tilt detection plate 40 described above can slide. The first elongated hole 15 is integrally formed with an arc hole portion 15 a formed in an arc shape centering on the support shaft 8 and a linear hole portion 15 b formed linearly. Therefore, the lever plate 10 can be rotated independently regardless of the rotation position of the lock plate 20 when the first slide pin 42 relatively slides within the arc hole 15a of the first long hole 15. It becomes. A lever pin 12 is formed on the front side of the lever plate 10 so as to protrude in the plate thickness direction.

  Here, as shown in FIG. 11, a lock plate 20 made of an arm-shaped plate member is also pivotally supported on the support shaft 8 that pivotally supports the lever plate 10 described above. Yes. The lock plate 20 is formed in a band plate shape, and a substantially central portion is pivotally supported by the support shaft 8 so as to be rotatable. On one end side of the lock plate 20, a second long hole 25 is formed in which the first slide pin 42 of the forward tilt detection plate 40 (forward tilt detection mechanism) described above can slide. The second long hole 25 is formed in the same shape as the straight hole portion 15 b of the first long hole 15. As a result, the lever plate 10 and the lock plate 20 are moved forward when the straight hole portion 15b of the first elongated hole 15 and the second elongated hole 25 are not aligned as shown in FIGS. As the first slide pin 42 slides, the lock plate 20 follows and rotates so that the straight hole portion 15b of the first elongated hole 15 and the second elongated hole 25 coincide with each other. The lock plate 20 is provided with a locking piece 22 that projects in the thickness direction. As shown in FIG. 12, when the lock plate 20 is rotated in the counterclockwise direction following the rotation of the lever plate 10, the lock plate 20 comes into contact with the edge of the lever plate 10 to be rotated a predetermined time. It is regulated by the moving angle. A cable hooking portion 21 for hooking the end portion of the inner member 9 a of the cushion lock cable 9 is formed on the other end side of the lock plate 20. The cable hook portion 21 is formed by partially bending the end portion of the lock plate 20. As shown in FIGS. 11 and 12, the lock plate 20 rotates in the rotation direction of the lever plate 10 following the lever plate 10 by the rotation operation of the operation lever L. The lock plate 20 pulls the end of the inner member 9a hooked to the lower end of the lock plate 20 and pulls the cushion member 9 from the end of the outer member 9b. Further, as shown in FIG. 13, in the lock plate 20, the first slide pin 42 slides and moves in a state where the straight hole portion 15 b of the first long hole 15 and the second long hole 25 coincide (overlapping state). Accordingly, it rotates around the support shaft 8 in synchronization with the lever plate 10 and returns to the initial position (similar to the position shown in FIG. 8).

  Here, as shown in FIGS. 8 to 11, on the support shaft 8 that pivotally supports the lever plate 10 described above, a slide plate 60 made of an arm-shaped plate member is also pivotally supported. Has been. The slide plate 60 is formed with a first arm 61 and a second arm 62 that extend in the radial direction from the support position of the support shaft 8 by a band plate-like plate member. A first rotating shaft 64 is provided on the distal end side of the first arm 61. A strip-shaped cancel link 70 is pivotally supported on the first rotation shaft 64 so as to be rotatable. The cancel link 70 is urged in the clockwise direction in the figure by the elastic urging of the second winding spring 66 interposed in the first rotating shaft 64 and is in a position where it comes into contact with the cancel stopper 68 provided on the first arm 61. Is retained. The front end of the cancel link 70 is provided with a flange 72 whose plate surface is bent. The flange 72 is set so as to be positioned on the rotation trajectory of the lever pin 12 in a state where the cancel link 70 is held at a position in contact with the cancel stopper 68. The cancel link 70 has a second rotation shaft 74 on the flange 72 side. A strip-like slide position detection plate 76 (position detection mechanism) is pivotally supported on the second rotation shaft 74 so as to be rotatable. At the tip of the slide position detection plate, there is a detection pin 78 (engaged member) protruding in the thickness direction. The detection pin 78 is slidably inserted in the slit 3h formed in the cushion frame 3f by cutting out in the vehicle front-rear direction. The second arm 62 is formed with a cable hooking portion 63 for hooking the end portion of the inner member 29a of the slide lock cable 29. The cable hook portion 63 is formed by partially bending the end portion of the slide plate 60.

  As a vehicle seat operation mode 1 described above, a mode in which the seat body 1 is in the standing state 1A and the operation lever L is rotated at an arbitrary slide position will be described with reference to FIGS. As shown in FIG. 1, the seat body 1 is in the standing state 1 </ b> A and is located at an arbitrary position in the slide movement range. This is a state when the occupant is seated on the seat body 1 and used. At this time, the operation mechanism 5 maintains the initial state as shown in FIG.

  As shown in FIG. 2, the operation lever L is pulled backward to perform the turning operation. Then, the suspended operation lever L rotates counterclockwise about the support shaft 8 as shown in FIG. At this time, there is a flange 72 of the cancel link 70 on the turning locus of the lever pin 12. Therefore, the slide plate 60 rotates counterclockwise around the support shaft 8 integrally with the operation lever L when the lever pin 12 pushes down the cancel link 70. Thereby, the inner member 29a hooked on the second arm 62 is pulled out from the outer member 29b. The slide lock cable 29 is pulled at one end side so that the inner member 29a is pulled out from the outer member 29b. The operating force of this pulling operation is transmitted to the lock claw 122 of the slide lock device 120 as shown in FIG. 7, and the lock claw 122 is rotated so that the claw is detached from the through hole 102h and the lower rail 104. As a result, the slide lock state by the lock claw 122 of the slide lock device 120 is released all at once, and the seat body 1 is switched to a state in which the seat body 1 can slide. Here, the rotation range of the operating lever L includes a first rotation range L1 and a second rotation range L2 adjacent to the first rotation range L1 from the initial position to the end of rotation. Are set continuously in the circumferential direction. The position rotated to the position where the slide lock state of the slide lock device 120 is released is the first rotation range L1. Further, the rotation range behind the first rotation range L1 is the second rotation range L2.

  As shown in FIG. 3, the seat body 1 is slid to the rearmost position 104z (specific slide position) by the slide mechanism 100 in a state where the operation lever L is operated. When the seat body 1 slides to the rearmost position 104z in the allowable slide range as shown in FIG. 10, the detection pin 78 (engaged member) of the slide position detection plate 76 (position detection mechanism) of the operation mechanism 5 and the lower rail A hooking plate 106 (engagement member) (position detection mechanism) provided on 104 is engaged. The detection pin 78 slides in the vehicle forward direction in the slit 3h. The cancel link 70 rotates in the counterclockwise direction shown in the figure against the urging force of the second winding spring 66 around the first rotation shaft 64. Then, the flange 72 retreats from the turning locus of the lever pin 12. As a result, the lever plate 10 changes from a state where the lever plate 10 rotates integrally with the slide plate 60 around the support shaft 8 to a state where the lever plate 10 can rotate independently. That is, the rotation operation of the operation lever L is performed by releasing the slide lock state of the slide lock device 120 in the first rotation range L1 and detecting the pin 78 (covered) of the slide position detection plate 76 (position detection mechanism). The shift to the second rotation range L2 is restricted until the position detection mechanism is detected by the engagement member) and the hook plate 106 (engagement member) (position detection mechanism).

  As shown in FIGS. 4 and 11, the operation mechanism 5 includes a detection pin 78 (an engaged member) of a slide position detection plate 76 (a position detection mechanism), and a hook plate 106 (an engagement member) (a position detection mechanism). When the rearmost position 104z is detected based on the relationship, the operation lever L can be further rotated to the second rotation range L2. At this time, the cancel link 70 rotates about the first rotation shaft 64 in the clockwise direction in the figure by the bias of the second winding spring 66, and rotates the slide plate 60 in the clockwise direction in the figure to the initial position. Return. Here, since the detection pin 78 of the slide position detection plate 76 has moved in the forward direction of the slit 3h, the cancel link 70 is held in a posture that does not return to a position where it comes into contact with the cancel stopper 68. In this state, the flange 72 is kept retracted from the pivot locus of the lever pin 12. As a result, the slide lock device 120 enters the slide lock state again. Further, when the operation lever L in a state that can be rotated independently is rotated to the second rotation range L2, the operation portion 11 of the lever plate 10 presses the roller 6e to integrally move the release arm 6a. Thereby, the operation lever L rotates the release arm 6a in the clockwise direction in the drawing to release the reclining lock state of each recliner 6.

  As shown in FIG. 5, in the seat body 1, the operation lever L is rotated to the second rotation range L <b> 2 (see FIG. 4), and the reclining lock state of the recliner 6 is simultaneously released to shift to the forward tilted state 1 </ b> B. . As shown in FIG. 12, as the seat back 2 tilts forward, the L-shaped spring-loaded bracket 2b engages with the engaging portion 32, and the rotating bracket 30 rotates counterclockwise in the figure. On the other hand, the connecting pin 38 moves upward. Since the forward fall detection plate 40 (forward fall detection mechanism) moves upward against the bias of the tension spring 44, the first slide pin 42 moves from the arc hole 15a of the first elongated hole 15 to the straight hole 15b. It slides and moves. The first slide pin 42 rotates the lock plate 20 in the counterclockwise direction shown in the drawing so that the straight hole portion 15b of the first long hole 15 and the second long hole 25 coincide with each other. Thereby, the lock plate 20 is rotated in the rotation direction of the lever plate 10 following the lever plate 10 by the rotation operation of the operation lever L. The lock plate 20 pulls the end of the inner member 9a hooked to the lower end of the lock plate 20 and pulls the cushion member 9 from the end of the outer member 9b. Thereby, the pulling operation of the cushion lock cable 9 is transmitted to the cushion lock 130, the striker S can be detached from the receiving portion 134a of the hook 134, and the hooked state with the striker S is released. Thus, the cushion lock device 130 can separate the connection between the floor surface F (vehicle component) and the seat body 1. That is, the rotation operation of the operation lever L is performed by the recliner 6 in the second rotation range L2 so that the seat body 1 is moved to the front tilt state 1B and the front tilt detection plate 40 (front tilt detection mechanism) is in the front tilt state 1B. Until the detection by is performed, the operation of the cushion lock device 130 (the connection / separation switching mechanism) in the separated state is restricted.

  As shown in FIGS. 6 and 13, the seat body 1 is stored in the second floor surface F <b> 2 by rotating the leg 140 in the separated state where the cushion lock state of the cushion lock device 130 is released to be in the storage state 1 </ b> C. . At this time, when the operation lever L is returned after the seat body 1 is separated from the first floor surface, the lever plate 10 and the lock plate 20 are aligned with the straight hole portion 15b of the first elongated hole 15 and the second elongated hole 25. As the first slide pin 42 slides and moves in a state (overlapping state), the first slide pin 42 rotates around the support shaft 8 synchronously and returns to the initial position (similar to the position shown in FIG. 8). As a result, the cushion lock device 130 enters the cushion lock state again. It should be noted that in the state where the engagement between the detection pin 78 (engaged member) of the slide position detection plate 76 (position detection mechanism) and the hook plate 106 (engagement member) (position detection mechanism) is maintained, the cancellation is performed. The state in which the flange 72 of the link 70 is retracted from the rotation locus of the lever pin 12 is maintained. Therefore, the operation lever L can return to the initial position.

  In the vehicle seat operation mode 1 described above, the mode in which the seat body 1 is in the standing state 1A and the operation lever L is rotated at an arbitrary slide position has been described. The vehicle seat operating mechanism 5 is in the stowed state regardless of whether the seat body 1 is in the upright state 1A or in the forwardly tilted state 1B, and the slide position of the seat body 1 is in any sliding position or the rearmost position 104z. Each mechanism is operated in conjunction so that it can be stored in 1C. Details of each operation mode will be described.

  As an operation mode 2, a mode in which the seat body 1 is in the forward tilted state 1B and the operation lever L is rotated at the rearmost position 104z (specific slide position) will be described with reference to FIGS. As shown in FIG. 14, the seat body 1 is in the forwardly tilted state 1 </ b> B and is located at the rearmost position 104 z (specific slide position). This is a state when the back surface of the seat back 2 is used for a table or the like, for example. At this time, in the operation mechanism 5, as shown in FIG. 14, the seat body 1 is located at the rearmost position 104z (specific slide position). Therefore, as shown in FIG. 15, the engagement between the detection pin 78 (engaged member) of the slide position detection plate 76 (position detection mechanism) and the hook plate 106 (engagement member) (position detection mechanism) is maintained. It is the state that was done. Therefore, the flange 72 of the cancel link 70 is kept in a state of being retracted from the turning locus of the lever pin 12. Therefore, the operation lever L is rotated independently from the initial position and does not rotate the slide plate 60. Therefore, the slide lock device 120 is maintained in the slide lock state. The operation lever L passes through the first rotation range L1 and moves to the second rotation range L2. The lever plate 10 and the lock plate 20 are synchronized with the sliding movement of the first slide pin 42 in a state in which the linear hole portion 15b of the first long hole 15 and the second long hole 25 are aligned (overlapping state). It rotates about the support shaft 8 in the counterclockwise direction shown in the figure. At this time, when the operation lever L is rotated to the second rotation range L2, the operation unit 11 presses the roller 6e and integrally moves the release arm 6a, but the sheet body 1 is already in the forward tilted state 1B. The release arm 6a is in an idle state. On the other hand, as the lock plate 20 rotates in synchronism with the lever plate 10, it pulls the end of the inner member 9a hooked on the lower end thereof and pulls it out from the end of the outer member 9b. Then, the cushion lock cable 9 is pulled. Thereby, the pulling operation of the cushion lock cable 9 is transmitted to the cushion lock 130, the striker S can be detached from the receiving portion 134a of the hook 134, and the hooked state with the striker S is released. Thus, the cushion lock device 130 can separate the connection between the floor surface F (vehicle component) and the seat body 1. Accordingly, as in FIG. 6, the seat main body 1 is stored in the second floor surface F <b> 2 by rotating the leg 140 in the separated state where the cushion lock state of the cushion lock device 130 is released to be in the storage state 1 </ b> C. .

  As an operation mode 3, a mode when the seat body 1 is in the standing state 1A and the operation lever L is rotated at the rearmost position 104z (specific slide position) will be described with reference to FIGS. As shown in FIG. 16, the seat body 1 is in the standing state 1A and is located at the rearmost position 104z. This is a state where the occupant is seated and used on the seat body 1 at the rearmost position 104z. At this time, the operation mechanism 5 maintains the state shown in FIG. At this time, in the operation mechanism 5, as shown in FIG. 16, the seat body 1 is located at the rearmost position 104z (specific slide position). Therefore, as shown in FIG. 17, the engagement between the detection pin 78 (engaged member) of the slide position detection plate 76 (position detection mechanism) and the hook plate 106 (engagement member) (position detection mechanism) is maintained. It is the state that was done. Therefore, the flange 72 of the cancel link 70 is kept in a state of being retracted from the turning locus of the lever pin 12. Therefore, the operation lever L is rotated independently from the initial position and does not rotate the slide plate 60. Therefore, the slide lock device 120 is maintained in the slide lock state. The operation lever L passes through the first rotation range L1 and moves to the second rotation range L2. When the operation lever L in a state that can be rotated independently is rotated to the second rotation range L2, the operation portion 11 of the lever plate 10 presses the roller 6e to integrally move the release arm 6a. Thereby, the operation lever L rotates the release arm 6a in the clockwise direction in the drawing to release the reclining lock state of each recliner 6. In the seat body 1, the operation lever L is rotated to the second rotation range L2 as in FIG. As the seat back 2 is tilted forward as shown in FIG. 17, the L-shaped spring-loaded bracket 2 b engages with the engaging portion 32 to rotate the rotating bracket 30 in the counterclockwise direction shown in the figure. On the other hand, the connecting pin 38 moves upward. Since the forward fall detection plate 40 (forward fall detection mechanism) moves upward against the bias of the tension spring 44, the first slide pin 42 moves from the arc hole 15a of the first elongated hole 15 to the straight hole 15b. It slides and moves. The first slide pin 42 rotates the lock plate 20 in the counterclockwise direction shown in the drawing so that the straight hole portion 15b of the first long hole 15 and the second long hole 25 coincide with each other. Thereby, the lock plate 20 is rotated in the rotation direction of the lever plate 10 following the lever plate 10 by the rotation operation of the operation lever L. The lock plate 20 pulls the end of the inner member 9a hooked to the lower end of the lock plate 20 and pulls the cushion member 9 from the end of the outer member 9b. Thereby, the pulling operation of the cushion lock cable 9 is transmitted to the cushion lock 130, the striker S can be detached from the receiving portion 134a of the hook 134, and the hooked state with the striker S is released. Thus, the cushion lock device 130 can separate the connection between the floor surface F (vehicle component) and the seat body 1. Accordingly, as in FIG. 6, the seat main body 1 is stored in the second floor surface F <b> 2 by rotating the leg 140 in the separated state where the cushion lock state of the cushion lock device 130 is released to be in the storage state 1 </ b> C. .

  As an operation mode 4, a mode in which the seat body 1 is in the forward tilted state 1B and the operation lever L is rotated at an arbitrary slide position will be described with reference to FIGS. As shown in FIG. 18, the seat body 1 is in the forwardly tilted state 1 </ b> B and is located at an arbitrary slide position. This is a state when the back surface of the seat back 2 is used for a table or the like, for example. As shown in FIG. 21, the operation lever L is pulled backward to perform the rotation operation. Then, the suspended operating lever L rotates in the first rotation range L1 counterclockwise around the support shaft 8. At this time, there is a flange 72 of the cancel link 70 on the turning locus of the lever pin 12. Therefore, the slide plate 60 rotates counterclockwise around the support shaft 8 integrally with the operation lever L when the lever pin 12 pushes down the cancel link 70. Thereby, the inner member 29a hooked on the second arm 62 is pulled out from the outer member 29b. The slide lock cable 29 is pulled at one end to pull the inner member 29a from the outer member 29b, and the operating force of this pulling operation is transmitted to the lock claw 122 of the slide lock device 120 to rotate the lock claw 122. Thus, the claw is detached from the through hole 102h and the lower rail 104. As a result, the slide lock state by the lock claw 122 of the slide lock device 120 is released all at once, and the seat body 1 is switched to a state in which the seat body 1 can slide.

  As shown in FIG. 19, the seat body 1 is slid to the rearmost position 104z (specific slide position) by the slide mechanism 100 in a state where the operation lever L is operated. When the seat body 1 slides to the rearmost position 104z in the allowable slide range as shown in FIG. 22, the detection pin 78 (engaged member) of the slide position detection plate 76 (position detection mechanism) of the operation mechanism 5 and the lower rail A hooking plate 106 (engagement member) (position detection mechanism) provided on 104 is engaged. The detection pin 78 slides in the vehicle forward direction in the slit 3h. The cancel link 70 rotates in the counterclockwise direction shown in the figure against the urging force of the second winding spring 66 around the first rotation shaft 64. Then, the flange 72 retreats from the turning locus of the lever pin 12.

  As shown in FIGS. 20 and 23, the operation lever L passes through the first rotation range L1 and shifts to the second rotation range L2. The lever plate 10 and the lock plate 20 are synchronized with the sliding movement of the first slide pin 42 in a state in which the linear hole portion 15b of the first long hole 15 and the second long hole 25 are aligned (overlapping state). It rotates about the support shaft 8 in the counterclockwise direction shown in the figure. At this time, when the operation lever L is rotated to the second rotation range L2, the operation unit 11 presses the roller 6e and integrally moves the release arm 6a, but the sheet body 1 is already in the forward tilted state 1B. The release arm 6a is in an idle state. On the other hand, as the lock plate 20 rotates in synchronism with the lever plate 10, it pulls the end of the inner member 9a hooked on the lower end thereof and pulls it out from the end of the outer member 9b. Then, the cushion lock cable 9 is pulled. Thereby, the pulling operation of the cushion lock cable 9 is transmitted to the cushion lock 130, the striker S can be detached from the receiving portion 134a of the hook 134, and the hooked state with the striker S is released. Thus, the cushion lock device 130 can separate the connection between the floor surface F (vehicle component) and the seat body 1. Accordingly, as in FIG. 6, the seat main body 1 is stored in the second floor surface F <b> 2 by rotating the leg 140 in the separated state where the cushion lock state of the cushion lock device 130 is released to be in the storage state 1 </ b> C. .

  As described above, according to the vehicle seat of the first embodiment, the position detection mechanism for detecting the predetermined rearmost position 104z (specific slide position) in the slide movement range of the seat body 1 is provided on the slide mechanism 100 side. And a detection pin 78 (engaged member) provided on the sheet body 1 side. The detection pin 78 is slid together with the sheet body 1 by the slide mechanism 100 to be hooked. The rear end position 104z is detected by engaging with the plate 106. That is, the detection pin 78 provided on the side of the seat body 1 that slides is configured to engage with the hook plate 106 provided on the slide mechanism 100 side. As a result, the occurrence of so-called position detection skip, in which the rearmost position 104z is not detected, is suppressed, and the reliability of detection of the rearmost position 104z can be further improved. Further, by providing the position detection mechanism on separate members of the slide mechanism 100 and the seat body 1, the degree of freedom in design can be increased since the degree of freedom in the arrangement of the position detection mechanism is increased.

  The slide lock device 120 (slide lock mechanism), the recliner 6 (reclining mechanism), the forward tilt detection plate 40 (forward tilt detection mechanism), the cushion lock device 130 (connection / separation switching mechanism), and the operation mechanism 5 And leg 140 (storage mechanism). Since the operation mechanism 5 is configured to operate each mechanism of the slide lock device 120, the recliner 6, and the cushion lock device 130 in conjunction with each other, each operation until the seat body 1 in the standing state 1A is stored on the second floor surface F2 is described. The operability can be improved by interlocking the operation of the mechanism. That is, the release of the slide lock device 120 allows the seat body 1 to be slid to the rearmost position 104z (specific slide position) by the slide mechanism 100, the hook plate 106 (engagement member), and the slide position detection plate 76. Based on the detection of the rearmost position 104z by the detection pin 78 (engaged member) of the (position detection mechanism), the recliner 6 causes the seat body 1 to fall forward, and the forward fall detection plate 40 (forward fall detection mechanism). ), The operation of bringing the cushion lock device 130 into the separated state based on the detection of the forwardly tilted state 1B of the seat back 2 is operated in conjunction with each other.

  In addition, since the rotation operation of the operation lever L and the direction in which the seat body 1 is slid to the rearmost position 104z are the same rear side, the direction of the load required for the operation is the same, so that the operation efficiency is improved. The improvement in operability can be further improved.

  Further, the operation of each mechanism until the seat body 1 in the standing state 1A is stored in the second floor surface F2 is restricted by the first rotation range L1 and the second rotation range L2 due to the rotation operation of the operation lever L. ing. Thereby, the reliability of interlocking of each mechanism in the operation mechanism 5 can be improved.

  Further, the detection pin 78 (engaged member) of the slide position detection plate 76 (position detection mechanism) of the position detection mechanism and the forward tilt detection plate 40 (forward tilt detection mechanism) are configured in the operation mechanism 5. Can be compact.

  Further, by configuring the storage position on the second floor surface F2 in the lower front part with respect to the seat body 1, a vehicle seat having a high storage capacity can be obtained.

<Embodiment 2>
Next, Embodiment 2 will be described with reference to FIGS. In the second embodiment, an operation mechanism 205 is configured instead of the operation mechanism 5 in the first embodiment. Therefore, portions of the second embodiment that are common to the first embodiment will be described with reference to FIGS.

  The configuration of the operation mechanism 205 will be described with reference to FIGS. In the operation mechanism 5 according to the first embodiment, the operation lever L is configured integrally with the lever plate 10. In the operation mechanism 5, the lever plate 10 and the slide plate 60 are configured separately. On the other hand, the operation mechanism 205 of the second embodiment is configured to be divided into a first lever plate 210 and a second lever plate 212. The operation mechanism 205 integrates the function of the slide plate into the first lever plate 210. In the operation mechanism 5, a slide position detection plate 76 is configured. Instead, in the operation mechanism 205, the slide position detection plate 276 is configured to engage with the first lever plate 210 and the second lever plate 212, and the cancel link 70 is not configured. Further, the first winding spring 8 s in the operation mechanism 5 is not configured, and the first lever plate 210 is held in the initial rotation position state by receiving the action of the holding force from the slide lock device 120. Yes. Similarly to the operation mechanism 5, the lock plate 20 is held in the initial rotational position by receiving the action of the holding force from the cushion lock device 130. Since other configurations are substantially the same as those in the first embodiment, the same configurations may be denoted by the same reference numerals, and illustration and description thereof may be omitted.

  A first lever plate 210 made of an arm-shaped plate member is pivotally connected to the cushion frame 3f by a support shaft 8 so as to be rotatable. The first lever plate 210 has a plate surface projecting radially forward from the support shaft 8, and an end portion of the operation lever L is integrally attached and fixed in a hanging manner from the plate surface. As a result, the first lever plate 210 is rotated integrally with the operation lever L. A strip-like slide arm 218 protrudes between the support position of the support shaft 8 of the first lever plate 210 and the operation lever L, and one end of the inner member 29a of the slide lock cable 29 is hooked on the tip. A cable hook 219 to be worn is provided. The plate surface of the first lever plate 210 is provided with a third long hole 216. The third elongated hole 216 is formed integrally with an arcuate arc hole 216a centered on the support shaft 8 and a linear rectilinear hole 216b. Therefore, when the second slide pin 277 of the slide position detection plate 276, which will be described later, slides and moves along the arc hole 216a of the third long hole 216, the first lever plate 210 has the lock plate 20 and the second lever plate 212. It can be rotated independently regardless of the rotation position. A second lever plate 212 made of an arm-like plate member is also pivotally supported on the support shaft 8 that pivotally supports the lever plate 10.

  The second lever plate 212 has a plate surface projecting from the support shaft 8 in the front-rear direction in the radial direction. The second lever plate 212 is provided with a fourth long hole 217 on the front plate surface from the support shaft 8. The fourth long hole 217 is formed in the same shape as the straight hole 216 b in the third long hole 216 of the first lever plate 210. The second lever plate 212 is provided with a first long hole 215 similar to the first long hole 15 of the lever plate 10 on the plate surface on the rear side from the support shaft 8. The first elongated hole 215 is formed integrally with an arcuate arc hole 215 a centering on the support shaft 8 and a straight hole 215 b having the same shape as the second elongated hole 25 of the lock plate 20. Therefore, when the first slide pin 42 of the forward tilt detection plate 40 (forward tilt detection mechanism) slides and moves along the arc hole 215a of the first long hole 215, the second lever plate 212 rotates the lock plate 20. It can be rotated independently regardless of the movement position. The second lever plate 212 is provided with an operation unit 211 similar to the operation unit 11 of the lever plate 10.

  The slide position detection plate 276 is a belt-like plate member. A detection pin 278 (engaged member) similar to the detection pin 78 of the slide position detection plate 76 is provided below the slide position detection plate 276. A second slide pin 277 is provided above the slide position detection plate 276. The second slide pin 277 is slidably inserted through the third long hole 216 and the fourth long hole 217.

  As the vehicle seat operation mode 5 of the second embodiment described above, FIGS. 6, 24 to 29 will be described. As shown in FIG. 1, the seat body 1 is in the standing state 1 </ b> A and is located at an arbitrary position in the slide movement range. This is a state when the occupant is seated on the seat body 1 and used. At this time, the operation mechanism 205 maintains the initial state as shown in FIGS.

  As shown in FIG. 2, the operation lever L is pulled backward to perform the turning operation. Then, the suspended operation lever L rotates counterclockwise about the support shaft 8 as shown in FIG. Since the second slide pin 277 of the slide position detection plate 276 slides within the arc hole 216a of the third long hole 216, the first lever plate 210 rotates independently. Then, along with the operation lever L, the slide arm 218 also rotates counterclockwise about the support shaft 8. For this reason, the slide lock cable 29 hooked on the slide arm 218 is subjected to a pulling operation in which one end of the inner member 29a is pulled out from the outer member 29b. As shown in FIG. 24, the operating force of the pulling operation is transmitted to the lock claw 122 of the slide lock device 120 to rotate the lock claw 122, and the claw is detached from the through hole 102 h and the lower rail 104. As a result, the slide lock state by the lock claw 122 of the slide lock device 120 is released all at once, and the seat body 1 is switched to a state in which the seat body 1 can slide. Here, the rotation range of the operating lever L includes a first rotation range L1 centered on the support shaft 8 and a second rotation range L2 between the initial position and the end of rotation. It is set adjacent to the radial direction. The position where the operation lever L integrated with the first lever plate 210 is rotated to the position where the slide lock state of the slide lock device 120 is released is the first rotation range L1 in the second embodiment. Further, on the radially inner side from the first rotation range L1, a rotation range in which a second lever plate 212 described later rotates about the support shaft 8 is a second rotation range L2.

  As shown in FIG. 3, the seat body 1 is slid to the rearmost position 104z (specific slide position) by the slide mechanism 100 in a state where the operation lever L is operated. When the seat body 1 slides to the rearmost position 104z in the allowable slide range as shown in FIG. 27, the detection pin 278 (engaged member) of the slide position detection plate 276 (position detection mechanism) of the operation mechanism 205 and the lower rail A hooking plate 106 (engagement member) (position detection mechanism) provided on 104 is engaged. The detection pin 278 slides in the slit 3h in the vehicle forward direction. Then, the second slide pin 277 of the slide position detection plate 276 moves downward. Then, the second slide pin 277 slides and moves from the arc hole 216a of the third long hole 216 toward the straight hole 216b. The second slide pin 277 rotates the second lever plate 212 following the second lever plate 212 so that the straight hole portion 216b of the third elongated hole 216 and the fourth elongated hole 217 coincide with each other. As a result, the second lever plate 212 rotates in the rotating direction of the first lever plate 210 following the first lever plate 210 integrated with the operating lever L by the rotating operation of the operating lever L. At this time, since the first slide pin 42 of the forward tilt detection plate 40 (forward tilt detection mechanism) slides in the arc hole 215a of the first long hole 215, the second lever plate 212 rotates the lock plate 20. Rotate independently without affecting movement. In addition, when the second lever plate 212 that rotates independently is rotated to the second rotation range L2, the operation portion 211 of the second lever plate 212 presses the roller 6e to integrally move the release arm 6a. . Thereby, the operation lever L rotates the release arm 6a in the clockwise direction in the drawing to release the reclining lock state of each recliner 6. In other words, the rotation operation of the operation lever L is performed by releasing the slide lock state of the slide lock device 120 in the first rotation range L1 and detecting the pin 278 (covered) of the slide position detection plate 276 (position detection mechanism). The rotation movement of the second lever plate 212 to the second rotation range L2 is restricted until the position detection mechanism is detected by the engagement member) and the hook plate 106 (engagement member) (position detection mechanism). The

  As shown in FIG. 5, in the seat main body 1, the second lever plate 212 is rotated to the second rotation range L <b> 2, and the reclining lock state of the recliner 6 is simultaneously released to shift to the forward tilt state 1 </ b> B. As shown in FIG. 28, as the seat back 2 is tilted forward, the L-shaped spring-hanging bracket 2b engages with the engaging portion 32 to rotate the rotating bracket 30 counterclockwise. On the other hand, the connecting pin 38 moves upward. Since the forward fall detection plate 40 (forward fall detection mechanism) moves upward, the first slide pin 42 slides from the arc hole 215a of the first long hole 215 toward the straight hole 215b. The first slide pin 42 rotates the lock plate 20 in the counterclockwise direction shown in the figure so that the straight hole portion 215b of the first long hole 215 and the second long hole 25 coincide with each other. Thereby, the lock plate 20 is rotated in the rotation direction of the second lever plate 212 following the second lever plate 212 by the rotation operation of the operation lever L. The lock plate 20 pulls the end of the inner member 9a hooked to the lower end of the lock plate 20 and pulls the cushion member 9 from the end of the outer member 9b. Thereby, the pulling operation of the cushion lock cable 9 is transmitted to the cushion lock 130, the striker S can be detached from the receiving portion 134a of the hook 134, and the hooked state with the striker S is released. Thus, the cushion lock device 130 can separate the connection between the floor surface F (vehicle component) and the seat body 1. That is, the turning operation of the operation lever L is performed by operating the seat body 1 to the forward-turned state 1B by the recliner 6 in the second turning range L2 of the second lever plate 212 and the forward-falling detection plate 40 (forward-falling detection mechanism ) Of the cushion lock device 130 (connection / separation switching mechanism) is regulated until the detection in the forward tilt state 1B is performed.

  As shown in FIGS. 6 and 29, the seat body 1 is stored in the second floor surface F2 by rotating the leg 140 in the separated state in which the cushion lock state of the cushion lock device 130 is released to be in the storage state 1C. . At this time, when the operation lever L is returned after the seat body 1 is separated from the first floor surface, the first lever plate 210 and the second lever plate 212 have the straight hole portion 216b and the fourth long hole 217 of the third long hole 216. As the second slide pin 277 slides and moves in a state in which the two coincide with each other (overlapping state), the second slide pin 277 rotates around the support shaft 8 synchronously and returns to the initial position (similar to the positions shown in FIGS. 24 and 25). . Further, the second lever plate 212 and the lock plate 20 are configured such that the first slide pin 42 slides and moves in a state where the straight hole portion 215b of the first long hole 215 and the second long hole 25 coincide (overlapping state). Accordingly, it rotates around the support shaft 8 synchronously and returns to the initial position (similar to the positions shown in FIGS. 24 and 25). As a result, the cushion lock device 130 enters the cushion lock state again. The slide lock device 120 is again in the slide lock state.

  The above-described operation mode of the vehicle seat has been described in the case where the seat body 1 is in the standing state 1A and the operation lever L is rotated at an arbitrary slide position. The vehicle seat operation mechanism 205 may be in any state of the seat body 1 in the standing state 1A and the forwardly tilted state 1B. Operate each mechanism so that it can be stored in Details of each operation mode will be described.

  As an operation mode 6, a mode in the case where the seat body 1 is in the forward tilted state 1B and the operation lever L is rotated at the rearmost position 104z (specific slide position) will be described with reference to FIGS. As shown in FIG. 14, the seat body 1 is in the forwardly tilted state 1 </ b> B and is located at the rearmost position 104 z (specific slide position). This is a state when the back surface of the seat back 2 is used for a table or the like, for example. At this time, in the operation mechanism 205, as shown in FIG. 14, the sheet main body 1 is located at the rearmost position 104z (specific slide position). Therefore, as shown in FIG. 30, the engagement between the detection pin 278 (engaged member) of the slide position detection plate 276 (position detection mechanism) and the hook plate 106 (engagement member) (position detection mechanism) is maintained. It is the state that was done. Therefore, the second slide pin 277 of the slide position detection plate 276 is located at a portion where the straight hole 216b of the first lever plate 210 and the fourth long hole 217 of the second lever plate 212 overlap. Further, the first slide pin 42 of the forward tilt detection plate 40 is located at a portion where the linear hole portion 215b of the first elongated hole 215 and the second elongated hole 25 overlap each other because the seat body 1 is in the forwardly tilted state 1B. . For this reason, the first lever plate 210, the second lever plate 212, and the lock plate 20 are rotated about the support shaft 8 in the counterclockwise direction shown in the figure. Thereby, the first lever range 210 in the second embodiment is obtained by rotating the operation lever L integrated with the first lever plate 210. Then, when the operation lever L is rotated to the first rotation range L1, the slide arm 218 is also rotated counterclockwise about the support shaft 8. For this reason, the slide lock cable 29 hooked on the slide arm 218 is subjected to a pulling operation in which one end of the inner member 29a is pulled out from the outer member 29b. As shown in FIG. 24, the operating force of the pulling operation is transmitted to the lock claw 122 of the slide lock device 120 to rotate the lock claw 122, and the claw is detached from the through hole 102 h and the lower rail 104. As a result, the slide lock state by the lock claw 122 of the slide lock device 120 is released all at once, and the seat body 1 is switched to a state in which the seat body 1 can slide. The second lever plate 212 and the lock plate 20 are synchronized with the sliding movement of the first slide pin 42 in a state where the straight hole portion 215a of the first long hole 215 and the second long hole 25 are aligned (overlapping state). Then, it rotates in the counterclockwise direction shown in the figure around the support shaft 8. Thereby, the 2nd lever plate 212 rotates to the 2nd rotation range L2. On the other hand, when the second lever plate 212 is rotated to the second rotation range L2, the operation unit 211 presses the roller 6e to integrally move the release arm 6a. However, since the seat body 1 is already in the forward-turned state 1B, the release arm 6a is in an idle state. On the other hand, as the lock plate 20 rotates in synchronism with the lever plate 10, it pulls the end of the inner member 9a hooked on the lower end thereof and pulls it out from the end of the outer member 9b. Then, the cushion lock cable 9 is pulled. Thereby, the pulling operation of the cushion lock cable 9 is transmitted to the cushion lock 130, the striker S can be detached from the receiving portion 134a of the hook 134, and the hooked state with the striker S is released. Thus, the cushion lock device 130 can separate the connection between the floor surface F (vehicle component) and the seat body 1. Accordingly, as in FIG. 6, the seat main body 1 is stored in the second floor surface F <b> 2 by rotating the leg 140 in the separated state where the cushion lock state of the cushion lock device 130 is released to be in the storage state 1 </ b> C. .

  As an operation mode 7, a mode in the case where the seat body 1 is in the standing state 1A and the operation lever L is rotated at the rearmost position 104z (specific slide position) will be described with reference to FIGS. As shown in FIG. 16, the seat body 1 is in the standing state 1A and is located at the rearmost position 104z. This is a state where the occupant is seated and used on the seat body 1 at the rearmost position 104z. At this time, the operation mechanism 205 maintains the state shown in FIG. At this time, in the operation mechanism 205, as shown in FIG. 16, the sheet main body 1 is located at the rearmost position 104z (specific slide position). Therefore, as shown in FIG. 31, the engagement between the detection pin 278 (engaged member) of the slide position detection plate 276 (position detection mechanism) and the hook plate 106 (engagement member) (position detection mechanism) is maintained. It is the state that was done. Therefore, the second slide pin 277 of the slide position detection plate 276 is located at a portion where the straight hole 216b of the first lever plate 210 and the fourth long hole 217 of the second lever plate 212 overlap. For this reason, the first lever plate 210, the second lever plate 212, and the lock plate 20 are rotated about the support shaft 8 in the counterclockwise direction shown in the figure. Thereby, the first lever range 210 in the second embodiment is obtained by rotating the operation lever L integrated with the first lever plate 210. Then, when the operation lever L is rotated to the first rotation range L1, the slide arm 218 is also rotated counterclockwise about the support shaft 8. For this reason, the slide lock cable 29 hooked on the slide arm 218 is subjected to a pulling operation in which one end of the inner member 29a is pulled out from the outer member 29b. As shown in FIG. 24, the operating force of the pulling operation is transmitted to the lock claw 122 of the slide lock device 120 to rotate the lock claw 122, and the claw is detached from the through hole 102 h and the lower rail 104. As a result, the slide lock state by the lock claw 122 of the slide lock device 120 is released all at once, and the seat body 1 is switched to a state in which the seat body 1 can slide. On the other hand, the second lever plate 212 rotates the lock plate 20 because the first slide pin 42 of the forward tilt detection plate 40 (forward tilt detection mechanism) slides in the arc hole portion 215a of the first long hole 215. Rotate independently without affecting In addition, when the second lever plate 212 that rotates independently is rotated to the second rotation range L2, the operation portion 211 of the second lever plate 212 presses the roller 6e to integrally move the release arm 6a. . Thereby, the operation lever L rotates the release arm 6a in the clockwise direction in the drawing to release the reclining lock state of each recliner 6. As shown in FIG. 16, in the seat main body 1, the second lever plate 212 is rotated to the second rotation range L <b> 2, and the reclining lock state of the recliner 6 is simultaneously released to shift to the forward tilted state 1 </ b> B. As the seat back 2 is tilted forward as shown in FIG. 31, the L-shaped spring-loaded bracket 2 b engages with the engaging portion 32 to rotate the rotating bracket 30 in the counterclockwise direction shown in the figure. On the other hand, the connecting pin 38 moves upward. Since the forward fall detection plate 40 (forward fall detection mechanism) moves upward, the first slide pin 42 slides from the arc hole 215a of the first long hole 215 toward the straight hole 215b. The first slide pin 42 rotates the lock plate 20 in the counterclockwise direction shown in the figure so that the straight hole portion 215b of the first long hole 215 and the second long hole 25 coincide with each other. Thereby, the lock plate 20 is rotated in the rotation direction of the second lever plate 212 following the second lever plate 212 by the rotation operation of the operation lever L. The lock plate 20 pulls the end of the inner member 9a hooked to the lower end of the lock plate 20 and pulls the cushion member 9 from the end of the outer member 9b. Thereby, the pulling operation of the cushion lock cable 9 is transmitted to the cushion lock 130, the striker S can be detached from the receiving portion 134a of the hook 134, and the hooked state with the striker S is released. Thus, the cushion lock device 130 can separate the connection between the floor surface F (vehicle component) and the seat body 1. Accordingly, as in FIG. 6, the seat main body 1 is stored in the second floor surface F <b> 2 by rotating the leg 140 in the separated state where the cushion lock state of the cushion lock device 130 is released to be in the storage state 1 </ b> C. .

  As an operation mode 8, a mode in which the seat body 1 is in the forward tilted state 1B and the operation lever L is rotated at an arbitrary slide position will be described with reference to FIGS. As shown in FIG. 18, the seat body 1 is in the forwardly tilted state 1 </ b> B and is located at an arbitrary slide position. This is a state when the back surface of the seat back 2 is used for a table or the like, for example. As shown in FIG. 32, the operation lever L is pulled backward to perform the turning operation. Then, the suspended operating lever L rotates in the first rotation range L1 counterclockwise around the support shaft 8. As shown in FIG. 19, the operation lever L is pulled backward to perform the rotation operation. Then, the suspended operation lever L rotates counterclockwise about the support shaft 8 as shown in FIG. Since the second slide pin 277 of the slide position detection plate 276 slides within the arc hole 216a of the third long hole 216, the first lever plate 210 rotates independently. Then, along with the operation lever L, the slide arm 218 also rotates counterclockwise about the support shaft 8. For this reason, the slide lock cable 29 hooked on the slide arm 218 is subjected to a pulling operation in which one end of the inner member 29a is pulled out from the outer member 29b. As shown in FIG. 24, the operating force of the pulling operation is transmitted to the lock claw 122 of the slide lock device 120 to rotate the lock claw 122, and the claw is detached from the through hole 102 h and the lower rail 104. As a result, the slide lock state by the lock claw 122 of the slide lock device 120 is released all at once, and the seat body 1 is switched to a state in which the seat body 1 can slide. As shown in FIG. 19, the seat body 1 is slid to the rearmost position 104z (specific slide position) by the slide mechanism 100 in a state where the operation lever L is operated. When the seat body 1 is slid to the rearmost position 104z in the allowable slide range as shown in FIG. 33, the detection pin 278 (engaged member) of the slide position detection plate 276 (position detection mechanism) of the operation mechanism 205 and the lower rail A hooking plate 106 (engagement member) (position detection mechanism) provided on 104 is engaged. The detection pin 278 slides in the slit 3h in the vehicle forward direction. Then, the second slide pin 277 of the slide position detection plate 276 moves downward. Then, the second slide pin 277 slides and moves from the arc hole 216a of the third long hole 216 toward the straight hole 216b. The second slide pin 277 rotates the second lever plate 212 following the second lever plate 212 so that the straight hole portion 216b of the third elongated hole 216 and the fourth elongated hole 217 coincide with each other. As a result, the second lever plate 212 rotates in the rotating direction of the first lever plate 210 following the first lever plate 210 integrated with the operating lever L by the rotating operation of the operating lever L. Further, the first slide pin 42 of the forward tilt detection plate 40 is located at a portion where the linear hole portion 215b of the first elongated hole 215 and the second elongated hole 25 overlap each other because the seat body 1 is in the forwardly tilted state 1B. . Therefore, in the second lever plate 212 and the lock plate 20, the first slide pin 42 slides and moves in a state where the straight hole portion 215a of the first long hole 215 and the second long hole 25 are aligned (overlapping state). Accordingly, it rotates in the counterclockwise direction as a unit around the support shaft 8 in synchronization. Thereby, the 2nd lever plate 212 rotates to the 2nd rotation range L2. On the other hand, when the second lever plate 212 is rotated to the second rotation range L2, the operation unit 211 presses the roller 6e to integrally move the release arm 6a. However, since the seat body 1 is already in the forward-turned state 1B, the release arm 6a is in an idle state. On the other hand, as the lock plate 20 rotates in synchronism with the lever plate 10, it pulls the end of the inner member 9a hooked on the lower end thereof and pulls it out from the end of the outer member 9b. Then, the cushion lock cable 9 is pulled. Thereby, the pulling operation of the cushion lock cable 9 is transmitted to the cushion lock 130, the striker S can be detached from the receiving portion 134a of the hook 134, and the hooked state with the striker S is released. Thus, the cushion lock device 130 can separate the connection between the floor surface F (vehicle component) and the seat body 1. As a result, as in FIG. 20, the seat body 1 is stored in the second floor surface F2 by rotating the leg 140 in the separated state in which the cushion lock state of the cushion lock device 130 is released to be in the storage state 1C. . At this time, as shown in FIG. 34, when the operation lever L is returned after the sheet body 1 is separated from the first floor surface, the first lever plate 210 and the second lever plate 212 are linear hole portions of the third long hole 216. As the second slide pin 277 slides and moves in a state where the 216b and the fourth elongated hole 217 coincide with each other (overlapping state), the second pin 277 rotates around the support shaft 8 in synchronization with the initial position (see FIGS. 24 and 25). Return to the same position as shown). Further, the second lever plate 212 and the lock plate 20 are configured such that the first slide pin 42 slides and moves in a state where the straight hole portion 215b of the first long hole 215 and the second long hole 25 coincide (overlapping state). Accordingly, it rotates around the support shaft 8 synchronously and returns to the initial position (similar to the positions shown in FIGS. 24 and 25). As a result, the cushion lock device 130 enters the cushion lock state again. The slide lock device 120 is again in the slide lock state.

  Thus, according to the vehicle seat of the second embodiment, the same operational effects as those of the first embodiment can be obtained.

  As mentioned above, although Embodiment 1 and 2 of this invention were demonstrated, the vehicle seat of this invention is not limited to Embodiment 1 and 2, It can implement with other various forms. For example, the vehicle is not limited to a vehicle, and can be applied to various vehicles such as railroads, ships, and airplanes. Also, various storage positions can be selected. For example, it may be a so-called tumble seat that lifts and stores the rear side of the seat in the forward-falling state, or may be applied to a so-called space-up seat in which the seat in the forward-falling state is flipped up and stored on the side wall of the passenger compartment.

  Various configurations can be applied to the configuration in which the rotation operation of the operation lever and the direction in which the seat body is slid to the specific slide position are the same. That is, in this embodiment, although the example of the back side was shown as the same direction, the front side may be sufficient. Moreover, in the aspect which has a slide mechanism in the left-right direction of a vehicle, the left-right direction may be sufficient.
