  As shown in FIG. 7A, the support plate 94 is formed in a substantially rectangular plate shape, and is disposed on the sheet front side and the sheet upper side of the base plate 92 with the sheet vertical direction as the plate thickness direction. The support plate 94 is connected to the base plate 92 by a connection plate 100 described later. The support plate 94 is disposed below the seat of the slide plate 84 between the front ends of the side frames 16 in the SC frame 14 (see FIG. 1). Further, the position of the support plate 94 in the sheet width direction is set so that the sheet width direction center line of the support plate 94 and the sheet center line of the base plate 92 coincide.

  As shown in FIGS. 1 and 5, a support front plate 96 is provided at the front end portion of the support plate 94. The support front plate 96 is formed in a substantially long plate shape with the sheet width direction as the longitudinal direction, and is disposed with the sheet front-rear direction as the plate thickness direction. The upper end portion of the support front plate 96 is the support plate 94. It is joined to the front end of this by welding or the like. In the present embodiment, the support plate 94 and the support front plate 96 are configured as separate members, but the support plate 94 and the support front plate 96 may be configured as a single member. That is, the front end portion of the support plate 94 may be bent to the lower side of the seat to form the support front plate 96.

  Further, as shown in FIG. 7A, the support plate 94 is formed with a pair of left and right elongated holes 94A extending in the front-rear direction of the seat at portions on both ends in the seat width direction. The long hole 94A is disposed at a position corresponding to the weld nuts 88F and 88R (see FIG. 1) paired in the front-rear direction described above. The extending length of the long hole 94A is set to be longer than the distance between the pair of front and rear weld nuts 88F and 88R. Further, as shown in FIGS. 1 and 5, a resin collar 95 is integrally provided on the inner peripheral portion of the long hole 94A. The collar 95 is formed in a frame shape corresponding to the shape of the long hole, covers the inner peripheral surface of the long hole 94A, and slightly protrudes above the upper surface of the support plate 94 to the upper side of the sheet. Accordingly, a pair of left and right slide grooves 95 </ b> A extending in the front-rear direction of the seat is formed through the support plate 94 in the inner portion of the collar 95.

  In the pair of left and right slide grooves 95A, slide bolts 98 that are paired in the front-rear direction of the seat are inserted from the lower side of the seat. The slide bolt 98 is configured as a stepped bolt. That is, the slide bolt 98 includes a head 98A, a cylindrical bolt main body 98B extending from the head 98A to the upper side of the seat, and a screw portion 98C extending from the upper end of the bolt main body 98B to the upper side of the seat. It is configured to include. Then, the slide bolt 98 is inserted into the slide groove 95A from the lower side of the seat through the washer W, and the screw portions 98C of the slide bolt 98 are screwed into the weld nuts 88F and 88R, respectively. Further, when the slide bolt 98 is screwed into the weld nuts 88F and 88R, the upper end of the bolt main body 98B is set so as to slightly protrude from the collar 95 to the upper side of the seat. Accordingly, the bolt main body 98B is configured to slide in the front-rear direction of the seat inside the slide groove 95A. In other words, the first bracket 82 connected to the ottoman device 20 (the base bracket 26 thereof) is connected to the support plate 94 so as to be slidable in the front-rear direction of the seat by the slide bolt 98, and from the lower side of the seat by the support plate 94. It is supported.

  In the following description, in the slide mechanism 80, the position where the seat rear slide bolt 98 is disposed at the rear end portion of the slide groove 95A is referred to as an initial position, and the seat front slide bolt 98 is the front end of the slide groove 95A. The position arranged in the section is referred to as a slide position (position shown in FIG. 5). Further, in the retracted state of the ottoman device 20, the ottoman body 70 is disposed at the first retracted position at the initial position of the slide mechanism 80, and the ottoman body 70 is disposed at the second retracted position at the slide position of the slide mechanism 80. It has become. Furthermore, in the slide mechanism 80, the slide amount (distance from the initial position to the slide position) of the first bracket 82 is set to 70 mm as an example.

  As shown in FIGS. 5 and 7A, the connecting plate 100 is formed in a substantially long plate shape, and the sheet extends from the front end to the rear end of the support plate 94 on the lower side of the support plate 94. It extends in the front-rear direction. Specifically, the connecting plate 100 is disposed on both sides in the sheet width direction with respect to the slide groove 95A of the support plate 94, with the sheet width direction as the plate thickness direction. Further, the connecting plate 100 disposed on the outer side in the sheet width direction with respect to the slide groove 95 </ b> A is disposed on the lower side of the sheet at both ends in the sheet width direction of the support plate 94. The front end of the connection plate 100 is joined to the rear surface of the support front plate 96 by welding or the like, and the upper end of the connection plate 100 is joined to the lower surface of the support plate 94 by welding or the like.

  The rear end portion of the connecting plate 100 is a connecting portion 100A, and the connecting portion 100A protrudes from the support plate 94 to the rear side of the seat and is inclined to the lower side of the seat in the side view. Yes. As shown in FIG. 7B, a notch 100B opened to the lower side of the sheet and the rear side of the sheet is formed at the lower end of the connecting part 100A. The notch 100B is joined to the upper surface of the base plate 92 and the front surface of the base flange 92C by welding or the like. Accordingly, the rear end portion (connecting portion 100A) of the connecting plate 100 is supported by the base plate 92 from the lower side of the seat and the rear side of the seat.

(About the slide drive unit 110)
As shown in FIGS. 4 and 6, the slide drive unit 110 is configured to slide the first rod 52, the slide motor unit 116, and the first rod 52 with respect to the SC frame 14 in the front-rear direction of the seat. And a slide feed screw 122. That is, the slide drive unit 110 is configured as a so-called feed screw mechanism. Further, the first rod 52 described above is configured as a common component used in common in the slide drive unit 110 and the link drive unit 50.

  As described above, the first rod 52 is bridged between the pair of left and right base brackets 26 in the link mechanism portion 24. The first rod 52 is provided with a second connection bracket 112 for connecting a slide feed screw 122, which will be described later, to the first rod 52. The second connection bracket 112 is the first connection bracket 54 described above. Is arranged on the left side of the seat. The second connection bracket 112 is formed in a substantially U shape that is open to the upper side of the seat, and the distal end portion of the second connection bracket 112 is fixed to the first rod 52. Further, a slide nut 114 as a “slide support member” is provided in the second connection bracket 112. The sliding nut 114 is pivotally supported by the second connecting bracket 112 with the seat width direction as the axial direction. Further, a through hole penetrating in the front-rear direction of the seat is formed inside the sliding nut 114, and a female screw is formed on the inner peripheral portion of the through hole.

  The slide motor unit 116 is disposed behind the seat of the slide nut 114 and is fixed to the lower surface of the base plate 92 via the slide motor bracket 120. The slide motor unit 116 has a slide motor 118, and the slide motor 118 is connected to a slide feed screw 122 described later. Further, the above-described control unit 66 (see FIG. 3) is electrically connected to the slide motor 118, and the slide motor 118 is operated by the control of the control unit 66.

  The slide feed screw 122 is formed in a substantially round bar shape and extends in the front-rear direction of the seat. A rear end portion (one end portion) of the slide feed screw 122 is disposed in the slide motor unit 116, is rotatably supported by the slide motor unit 116, and is connected to the slide motor 118. Thereby, the slide feed screw 122 is configured to rotate forward or backward around its own axis by operating the slide motor 118. A male screw is formed on the outer periphery of the slide feed screw 122. The front end side (the other end side) of the slide feed screw 122 is screwed to the slide nut 114.

  As a result, the slide feed screw 122 is rotated forward or backward by the operation of the slide motor 118, so that the slide nut 114 (first rod 52) moves relative to the slide feed screw 122 in the longitudinal direction of the seat. It is supposed to be. Specifically, when the slide feed screw 122 rotates forward, the slide nut 114 (first rod 52) moves relative to the slide feed screw 122 relative to the seat front side. On the other hand, when the slide feed screw 122 rotates in the reverse direction, the slide nut 114 (first rod 52) moves relative to the slide feed screw 122 relative to the seat rear side. Thus, the first bracket 82 (that is, the ottoman device 20) is configured to slide in the seat front-rear direction with respect to the second bracket 90 (that is, the SC frame 14) by the operation of the slide mechanism 80.

  As shown in FIG. 3, the vehicle seat 10 is provided with an operation unit 68 for operating the ottoman device 20 and the slide mechanism 80, and the operation unit 68 is electrically connected to the control unit 66. It is connected. The operation unit 68 has, for example, a use button that is operated when the ottoman device 20 is used, and a storage button that is operated when the ottoman device 20 is stored. When the seat occupant operates the use button, the slide mechanism 80 is activated, and the link mechanism 22 of the ottoman device 20 is activated after the slide mechanism 80 is activated. Accordingly, the ottoman body 70 is arranged from the first storage position to the second storage position, and is arranged from the second storage position to the leg rest position. On the other hand, when the seated occupant operates the storage button, the link mechanism 22 of the ottoman device 20 is activated, and the slide mechanism 80 is activated after the link mechanism 22 is activated. Accordingly, the ottoman body 70 is arranged from the leg placement position to the second storage position, and is arranged from the second storage position to the first storage position.

  Next, the operation and effect of the present embodiment will be described.

  In the vehicle seat 10 configured as described above, the ottoman body 70 is disposed at the first retracted position before the operation of the link mechanism 22 and the slide mechanism 80 (see FIG. 2). That is, the link mechanism portion 24 of the link mechanism 22 is in a folded state, and the slide plate 84 of the slide mechanism 80 is disposed at the initial position. And when using the ottoman apparatus 20, a seated passenger operates a use button. Accordingly, the slide mechanism 80 is operated under the control of the control unit 66, and the link mechanism 22 is operated after the slide mechanism 80 is operated, so that the ottoman main body 70 is arranged from the first storage position to the leg placement position.

  Specifically, the slide motor 118 of the slide mechanism 80 is operated by the control of the control unit 66, and the slide feed screw 122 is rotated in the forward direction. At this time, the slide feed screw 122 rotates relative to the slide nut 114, and the slide nut 114 moves relative to the slide feed screw 122 relative to the seat front side. Since the slide nut 114 is connected to the base bracket 26 of the link mechanism portion 24 via the first rod 52, when the slide nut 114 moves relative to the slide feed screw 122 toward the seat front side, The base bracket 26 slides to the front side of the seat together with the first bracket 82 (slide plate 84) of the slide mechanism 80. As a result, the first bracket 82 (slide plate 84) slides from the initial position to the slide position, and the ottoman device 20 (ottoman body 70) slides in the direction of arrow A in FIG. Arranged in the second storage position.

  Further, after the slide mechanism 80 is actuated, the link motor 62 of the link mechanism 22 is actuated by the control of the controller 66, and the link feed screw 64 is rotated forward. At this time, the link feed screw 64 moves relative to the link nut 56 so as to extend from the link nut 56. One end of the link feed screw 64 is connected to the drive link 28 via the link motor unit 60 and the second rod 58. For this reason, when the link feed screw 64 moves relative to the link nut 56, the link motor unit 60 and the second rod 58 are displaced to the seat front side with respect to the first rod 52, and the drive link 28 is linked to the link pin. The link mechanism 24 is unfolded from the retracted state by rotating around the LP axis (in the direction of arrow C in FIG. 2). As a result, the link mechanism 22 is operated, and the ottoman body 70 is rotated in the direction of arrow B in FIG. 2 and is disposed from the second storage position to the leg placement position (see FIG. 3). Accordingly, in the vehicular seat 10, it is possible to set the leg placement position to the position on the front side of the seat as compared with the case where the slide mechanism 80 is omitted.

  On the other hand, when the ottoman device 20 is stored in a state where the ottoman main body 70 is disposed at the leg rest position, the seated occupant operates the storage button. Accordingly, the link mechanism 22 is operated by the control of the control unit 66, the slide mechanism 80 is operated after the link mechanism 22 is operated, and the ottoman body 70 is arranged from the leg placement position to the first retracted position.

  Specifically, the link motor 62 of the link mechanism 22 is operated by the control of the control unit 66, and the link feed screw 64 rotates in the reverse direction. At this time, the link feed screw 64 moves relative to the link nut 56 so as to retract toward the link nut 56 side. For this reason, the drive link 28 rotates about the axis of the link pin LP (arrow D direction side in FIG. 3), and the link mechanism portion 24 is folded. As a result, the link mechanism 22 is actuated, and the ottoman body 70 is rotated in the direction of arrow E in FIG. 3 to be placed from the leg placement position to the second retracted position (see FIG. 3).

  Further, after the operation of the link mechanism 22, the slide motor 118 of the slide mechanism 80 is operated by the control of the control unit 66, and the slide feed screw 122 rotates in the reverse direction. At this time, the slide feed screw 122 rotates relative to the slide nut 114, and the slide nut 114 moves relative to the slide feed screw 122 toward the rear side of the seat. As described above, since the slide nut 114 is connected to the base bracket 26 of the link mechanism 22 via the first rod 52, the slide nut 114 is behind the seat with respect to the slide feed screw 122. When the base bracket 26 is relatively moved, the base bracket 26 slides to the rear side of the seat together with the first bracket 82 (slide plate 84) of the slide mechanism 80. As a result, the first bracket 82 (slide plate 84) is slid from the slide position to the initial position, and the ottoman main body 70 slides in the direction of the arrow F in FIG. 2 to change from the second storage position to the first storage position. Placed in.

  Here, in the vehicle seat 10, the slide mechanism 80 is provided between the ottoman device 20 and the SC frame 14, and the ottoman device 20 is slidably connected to the SC frame 14 by the slide mechanism 80. For this reason, compared with the case where a slide mechanism is provided in the ottoman apparatus 20 (specifically, when provided between the ottoman main body 70 and the link mechanism 22), an increase in the size and weight of the ottoman apparatus 20 is suppressed. In addition, riding comfort performance can be ensured.

  That is, if the slide mechanism is provided in the ottoman device 20, for example, a plate for sliding the ottoman body 70 in the front-rear direction of the seat and a drive unit for sliding the plate are connected to the ottoman body 70 and the link. It is necessary to arrange between the mechanisms 22. For this reason, when viewed from the side, the size of the ottoman body 70 increases in the longitudinal direction and the thickness direction of the ottoman body 70. And if the ottoman body 70 becomes larger in the longitudinal direction of the ottoman body 70, the ottoman body 70 may interfere with the floor of the vehicle at the first storage position and the second storage position of the ottoman body 70. In addition, when the ottoman body 70 is large in the thickness direction of the ottoman body 70, the protruding amount of the ottoman body 70 toward the front side of the seat cushion with respect to the seat cushion may increase at the first storage position and the second storage position of the ottoman body 70. There is.

  If the slide mechanism is provided in the ottoman device 20, the weight of the ottoman device 20 increases by the weight of the slide mechanism. Furthermore, in this case, since it is necessary to arrange a drive unit for sliding the ottoman body 70 between the ottoman body 70 and the link mechanism 22, the structure of the ottoman device 20 becomes complicated.

  Further, if the slide mechanism is provided between the ottoman body 70 and the link mechanism 22, the ottoman body 70 itself slides. Transmitted directly to the department. For this reason, there exists a possibility that the riding comfort performance with respect to a seated passenger may deteriorate.

  In contrast, in the present embodiment, the slide mechanism 80 is provided between the ottoman device 20 and the SC frame 14. For this reason, compared with the case where a slide mechanism is provided between the ottoman main body 70 and the link mechanism 22, the enlargement and weight increase of the ottoman main body 70 can be suppressed. Further, since the ottoman main body 70 is connected to the link mechanism 22 without using the slide mechanism 80, it is possible to suppress the play of the slide mechanism 80 from being directly transmitted to the seated occupant. Thereby, the riding comfort performance for the seated occupant can be ensured. As described above, it is possible to suppress the increase in size and weight of the ottoman device 20 and to ensure riding comfort performance.

  Further, the pair of left and right link mechanism portions 24 (base brackets 26) in the ottoman device 20 are connected by the first bracket 82 of the slide mechanism 80. Further, the pair of left and right side frames 16 of the SC frame 14 are connected by the second bracket 90 of the slide mechanism 80. For this reason, the pair of left and right link mechanism portions 24 and the SC frame 14 can be reinforced by utilizing the slide mechanism 80.

  Further, in the slide mechanism 80, a pair of left and right slide grooves 95A are formed in the second bracket 90, and a slide bolt 98 connected to the first bracket 82 is slidably provided in the slide groove 95A. ing. Thereby, the 1st bracket 82 and the 2nd bracket 90 can be slidably connected by simple composition.

  Further, as described above, in the slide mechanism 80, the first bracket 82 is provided between the pair of left and right link mechanism portions 24, and the second bracket 90 is provided between the pair of left and right side frames 16. . Therefore, for example, an existing ottoman device having a link mechanism can be slidably connected to the SC frame 14 by the slide mechanism 80.

  Further, in the second bracket 90 of the slide mechanism 80, the support plate 94 is provided on the seat front side and the seat upper side with respect to the base plate 92, and the support plate 94 is coupled to the base plate 92 by the coupling plate 100. Therefore, the support plate 94 and the base plate 92 can be connected by the connection plate 100 while the support plate 94 is disposed close to the lower side of the slide plate 84. Thereby, it can suppress that the axial length of the bolt main body 98B of the slide bolt 98 becomes extremely long. As a result, when the slide bolt 98 slides in the front-rear direction of the seat in the slide groove 95A, the slide bolt 98 can be prevented from being twisted with respect to the inner peripheral surface of the slide groove 95A. Therefore, the first bracket 82 (slide plate 84) can be slid well with respect to the second bracket 90 (support plate 94).

  Further, a notch portion 100B that is open to the lower side of the sheet and the rear side of the sheet is formed at the lower end portion of the connecting portion 100A (rear end portion) of the connecting plate 100. The notch portion 100B is the upper surface of the base plate 92. And joined to the front surface of the base flange 92C. Thereby, the support strength of the second bracket 90 with respect to the first bracket 82 can be increased, and the support performance of the slide mechanism 80 with respect to the ottoman device 20 can be increased.

  That is, in a state where the ottoman main body 70 is disposed at the leg placement position, the link mechanism portion 24 is deployed to the front side of the seat, and the ottoman main body 70 supports the leg portion of the seated occupant from the lower side of the seat. That is, the ottoman device 20 is configured like a cantilever with the base bracket 26 as a fixed end and the ottoman body 70 as an action point, and a load below the seat acts on the ottoman body 70. For this reason, counterclockwise rotational moment acts on the fixed end (base bracket 26) of the ottoman device 20 when viewed from the left side of the seat.

  On the other hand, in the second bracket 90 of the slide mechanism 80, the support plate 94 is disposed on the seat front side and the seat upper side with respect to the base plate 92, and is coupled to the base plate 92 by the coupling plate 100. Further, a first bracket 82 (support plate 94) is connected to the support plate 94 via a slide bolt 98, and the support plate 94 supports the first bracket 82 (support plate 94) from the lower side of the seat. Yes. For this reason, a rotational moment acts on the connection plate 100 as described above. As described above, the cutout portion 100B (rear end portion) of the connecting plate 100 is joined to the upper surface of the base plate 92 and the front surface of the base flange 92C. For this reason, the base flange 92C acts to receive the rotation of the connecting plate 100 from the rear side of the seat. Thereby, compared with the case where the connection part 100A of the connection plate 100 is joined only by the upper surface of the base plate 92, the support strength with respect to the 1st bracket 82 of the 2nd bracket 90 can be made high. As a result, the support performance of the slide mechanism 80 with respect to the ottoman device 20 can be enhanced.

  The slide mechanism 80 includes a slide drive unit 110. When the slide drive unit 110 operates, the first bracket 82 slides between the initial position and the slide position in the front-rear direction of the seat. The slide drive unit 110 includes a slide feed screw 122 that rotates by the operation of the slide motor 118, and a slide nut 114 that moves in the axial direction of the slide feed screw 122 by the rotation of the slide feed screw 122. The slide nut 114 is connected to the first rod 52. That is, the slide drive unit 110 is configured as a so-called feed screw mechanism. Accordingly, the first bracket 82 (that is, the ottoman device 20) can be automatically slid in the front-rear direction of the seat with a simple configuration.

  Further, in the slide mechanism 80, two slide bolts 98 are disposed in the pair of left and right slide grooves 95A formed in the support plate 94, spaced apart in the front-rear direction of the seat. For this reason, relative rotation with respect to the support plate 94 of the 1st bracket 82 at the time of the slide of the 1st bracket 82 can be suppressed compared with the structure which arrange | positions one slide bolt 98 in the slide groove | channel 95A temporarily. Thereby, when the 1st bracket 82 (Ottoman device 20) slides with respect to the support plate 94 (SC frame 14), the curvature with respect to the internal peripheral surface of the slide groove | channel 95A of the slide bolt 98 is suppressed effectively. Can do. As a result, the slide bolt 98 can be smoothly slid in the slide groove 95A.

  In the slide mechanism 80, the first rod 52 is disposed between the slide bolt 98 disposed on the front side of the seat and the slide bolt 98 disposed on the rear side of the seat as viewed from the lower side of the seat. For this reason, the driving force for sliding the first rod 52 in the front-rear direction of the seat acts between the pair of front and rear slide bolts 98. Thereby, the relative rotation with respect to the support plate 94 of the 1st bracket 82 at the time of the slide of the 1st bracket 82 can be suppressed more effectively. Therefore, when the first bracket 82 (Ottoman device 20) slides relative to the support plate 94 (SC frame 14), it is possible to more effectively suppress the sag of the slide bolt 98 with respect to the inner peripheral surface of the slide groove 95A. Can do.

  Further, the first rod 52 is configured as a common component that is used in common in the slide drive unit 110 in the slide mechanism 80 and the link drive unit 50 in the link mechanism 22. For this reason, the slide drive part 110 and the link drive part 50 can be provided in the vehicle seat 10 while suppressing an increase in the number of parts. Moreover, since the 1st rod 52 is comprised as a shared component in the slide drive part 110 and the link drive part 50, it can suppress that the installation space of the slide drive part 110 and the link drive part 50 in the vehicle seat 10 becomes large. . Therefore, an efficient arrangement structure can be realized in the slide drive unit 110 and the link drive unit 50.

  In the present embodiment, the slide mechanism 80 includes the first bracket 82 and the second bracket 90, and the first bracket 82 is slidably connected to the second bracket 90. The configuration of 80 is not limited to this. For example, the slide mechanism 80 may be configured by a slider provided so as not to move relative to the base bracket 26 and a rail provided on the side frame 16. In this case, the rail extends in the longitudinal direction of the seat, and the slider is slidably connected to the rail.

  Further, in the present embodiment, the slide mechanism 80 includes the slide drive unit 110, and the Ottoman device 20 automatically slides in the front-rear direction of the seat when the slide drive unit 110 operates. Instead of this, in the slide mechanism 80, the slide drive unit 110 may be omitted, and the ottoman device 20 may be manually slid in the front-rear direction of the seat. In this case, for example, a lock mechanism that prevents the slide bolt 98 from moving in the longitudinal direction of the seat is provided on the support plate 94 of the second bracket 90. Further, a release lever that releases the locked state of the slide bolt 98 by the lock mechanism may be provided on the side of the seat body 12. Then, the seated occupant may operate the release lever to release the locked state with respect to the slide bolt 98 by the lock mechanism, and manually slide the ottoman device 20.

  Further, in the present embodiment, the link mechanism 22 and the slide mechanism 80 are operated by the control of the control unit 66, and the ottoman body 70 is disposed from the first storage position to the second storage position, and from the second storage position. It is arranged at the position where the legs are placed. Instead, the operation of the slide mechanism 80 may be controlled by the controller 66 so that the ottoman body 70 is disposed at an arbitrary position between the first storage position and the second storage position. In this case, for example, the use button in the operation unit 68 may be composed of two buttons, that is, a use button for operating the slide mechanism 80 and a use button for operating the link mechanism 22. Then, the ottoman body 70 may be arranged at an arbitrary position between the first storage position and the second storage position by operating a use button for operating the slide mechanism 80.

  Further, in the slide mechanism 80 of the present embodiment, the slide groove 95A is formed in the support plate 94 of the second bracket 90, and the first bracket 82 (slide plate) is formed by the slide bolt 98 disposed in the slide groove 95A. 84) is slidably connected to the support plate 94. Instead, a slide groove 95A is formed in the slide plate 84 of the first bracket 82, and the first bracket 82 (slide plate 84) can be slid to the support plate 94 by a slide bolt 98 disposed in the slide groove 95A. You may connect to. In this case, the weld nuts 88F and 88R are fixed to the lower surface of the support plate 94 of the second bracket 90.

  In the slide mechanism 80 according to the present embodiment, the slide bolt 98 is configured to slide in the slide groove 95A in the front-rear direction of the seat, but the configuration of the slide bolt 98 is not limited thereto.
