4 and 6, the link driving unit 50 includes the first rod 52, the link motor unit 60, and the second rod 58 for connecting the link motor unit 60 to the drive link 28. It is comprised including. Further, the link drive unit 50 has a link feed screw 64 for rotating the drive link 28 relative to the base bracket 26. That is, the link drive unit 50 is configured as a so-called feed screw mechanism.
　第１ロッド５２は、前述のように、左右一対のベースブラケット２６に架け渡されている。この第１ロッド５２の長手方向中央部には、後述するリンク用送りねじ６４を第１ロッド５２に連結させるための第１連結ブラケット５４が設けられている。第１連結ブラケット５４は、シート上側へ開放された略Ｕ字形状に形成されており、第１連結ブラケット５４の先端部が、シート前側へ突出されて、第１ロッド５２に固定されている。また、第１連結ブラケット５４内には、「リンク用支持部材」としてのリンク用ナット５６が設けられており、リンク用ナット５６は第１連結ブラケット５４にシート幅方向を軸方向として軸支されている。また、リンク用ナット５６の中央部には、貫通孔が形成されており、貫通孔はシート幅方向に対して直交する方向に貫通されている。そして、貫通孔の内周部に雌ネジが形成されている。 The first rod 52 is bridged between the pair of left and right base brackets 26 as described above. A first connecting bracket 54 for connecting a link feed screw 64 (described later) to the first rod 52 is provided at the center in the longitudinal direction of the first rod 52. The first connection bracket 54 is formed in a substantially U shape that is open to the upper side of the seat, and the front end portion of the first connection bracket 54 protrudes to the front side of the seat and is fixed to the first rod 52. Further, a link nut 56 as a “link support member” is provided in the first connection bracket 54, and the link nut 56 is pivotally supported by the first connection bracket 54 with the seat width direction as an axial direction. ing. Further, a through hole is formed in the central portion of the link nut 56, and the through hole is penetrated in a direction orthogonal to the sheet width direction. And the internal thread is formed in the inner peripheral part of a through-hole.
　第２ロッド５８は、中空丸棒状とされて、シート幅方向を軸方向として、左右一対の駆動リンク２８の間に配置されている。そして、第２ロッド５８の長手方向両端部が、左右一対の駆動リンク２８の長手方向中間部に固定されている。また、第２ロッド５８には、リンクモータユニット６０を軸支するためのリンク用モータブラケット５９が固定されている。 The second rod 58 has a hollow round bar shape and is disposed between the pair of left and right drive links 28 with the seat width direction as the axial direction. The both ends of the second rod 58 in the longitudinal direction are fixed to the middle portion in the longitudinal direction of the pair of left and right drive links 28. A link motor bracket 59 for supporting the link motor unit 60 is fixed to the second rod 58.
　リンクモータユニット６０は、リンク用モータブラケット５９にシート幅方向を軸方向として回転可能に支持されている。また、リンクモータユニット６０は、リンク用モータ６２を有しており、リンク用モータ６２は、後述するリンク用送りねじ６４に連結されている。また、リンク用モータ６２には、制御部６６（図３参照）が電気的に接続されており、制御部６６の制御によってリンク用モータ６２が作動する構成になっている。 The link motor unit 60 is supported by the link motor bracket 59 so as to be rotatable about the seat width direction as an axial direction. The link motor unit 60 includes a link motor 62, and the link motor 62 is connected to a link feed screw 64 described later. Further, a controller 66 (see FIG. 3) is electrically connected to the link motor 62, and the link motor 62 is operated under the control of the controller 66.
　リンク用送りねじ６４は、略丸棒状に形成されて、シート幅方向に対して直交する方向を軸方向として、リンク用ナット５６とリンクモータユニット６０との間に配設されている。このリンク用送りねじ６４の長手方向一端部は、リンクモータユニット６０内に配置されて、リンクモータユニット６０に回転可能に支持されると共に、リンク用モータ６２に連結されている。これにより、リンク用モータ６２が作動することで、リンク用送りねじ６４が自身の軸回りに正回転又は逆回転するように構成されている。また、リンク用送りねじ６４の外周部には、雄ネジが形成されている。そして、リンク用送りねじ６４の長手方向他端側において、リンク用送りねじ６４がリンク用ナット５６に螺合されている。 The link feed screw 64 is formed in a substantially round bar shape, and is disposed between the link nut 56 and the link motor unit 60 with the direction orthogonal to the sheet width direction as the axial direction. One end of the link feed screw 64 in the longitudinal direction is disposed in the link motor unit 60, is rotatably supported by the link motor unit 60, and is connected to the link motor 62. Accordingly, the link feed screw 64 is configured to rotate forward or backward around its own axis by operating the link motor 62. A male screw is formed on the outer periphery of the link feed screw 64. The link feed screw 64 is screwed into the link nut 56 at the other longitudinal end of the link feed screw 64.
　これにより、リンク用モータ６２の作動によってリンク用送りねじ６４が正回転又は逆回転すると、リンク用送りねじ６４が自身の軸方向においてリンク用ナット５６に対して相対移動するようになっている。ここで、リンク用ナット５６は、第１ロッド５２に相対移動不能に連結されている。このため、リンク用送りねじ６４がリンク用ナット５６に対して軸方向に相対移動すると、第２ロッド５８が第１ロッド５２に対して相対移動するようになっている。具体的には、リンク用送りねじ６４が正回転すると、リンク用送りねじ６４がリンク用ナット５６から伸長されるようにリンク用ナット５６に対して相対移動する。これにより、リンクモータユニット６０及び第２ロッド５８が第１ロッド５２に対してシート前側へ変位すると共に、駆動リンク２８がリンクピンＬＰの軸回り（図２の矢印Ｃ方向側）に回動されて、リンク機構部２４が展開するようになっている。一方、リンク用送りねじ６４が逆回転すると、リンク用送りねじ６４がリンク用ナット５６側へ後退するようにリンク用ナット５６に対して相対移動する。これにより、リンクモータユニット６０及び第２ロッド５８が第１ロッド５２に対してシート後側へ変位すると共に、駆動リンク２８がリンクピンＬＰの軸回り（図２の矢印Ｄ方向側）に回動されて、リンク機構部２４が折畳まれるようになっている。 Thus, when the link feed screw 64 is rotated forward or reverse by the operation of the link motor 62, the link feed screw 64 is moved relative to the link nut 56 in its own axial direction. Here, the link nut 56 is connected to the first rod 52 so as not to be relatively movable. Therefore, when the link feed screw 64 moves relative to the link nut 56 in the axial direction, the second rod 58 moves relative to the first rod 52. Specifically, when the link feed screw 64 is rotated forward, the link feed screw 64 is moved relative to the link nut 56 so as to be extended from the link nut 56. As a result, the link motor unit 60 and the second rod 58 are displaced toward the seat front side with respect to the first rod 52, and the drive link 28 is rotated around the axis of the link pin LP (in the direction of arrow C in FIG. 2). Thus, the link mechanism 24 is developed. On the other hand, when the link feed screw 64 rotates in the reverse direction, the link feed screw 64 moves relative to the link nut 56 so as to move backward toward the link nut 56. As a result, the link motor unit 60 and the second rod 58 are displaced toward the rear side of the seat with respect to the first rod 52, and the drive link 28 rotates about the axis of the link pin LP (in the direction of arrow D in FIG. 2). As a result, the link mechanism 24 is folded.

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.
　そして、以下の説明では、スライド機構８０において、シート後側のスライドボルト９８がスライド溝９５Ａの後端部に配置された位置を初期位置と称し、シート前側のスライドボルト９８がスライド溝９５Ａの前端部に配置された位置をスライド位置（図５に示される位置）と称する。また、図２に示されるように、オットマン装置２０の格納状態では、スライド機構８０の初期位置においてオットマン本体７０が２点鎖線で示す第１格納位置に配置され、スライド機構８０のスライド位置においてオットマン本体７０が１点鎖線で示す第２格納位置に配置されるようになっている。さらに、スライド機構８０では、第１ブラケット８２のスライド量（初期位置からスライド位置までの距離）が、一例として７０ｍｍに設定されている。 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, as shown in FIG. 2, when the ottoman device 20 is in the retracted state, the ottoman body 70 is disposed at the first retracted position indicated by a two-dot chain line at the initial position of the slide mechanism 80, and at the slide position of the slide mechanism 80. The main body 70 is arranged at a second storage position indicated by a one-dot chain line. 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.
　図５及び図７Ａに示されるように、連結プレート１００は、略長尺板状に形成されて、支持プレート９４のシート下側において、支持プレート９４の前端から後端に亘ってシート前後方向に延在されている。具体的には、連結プレート１００は、シート幅方向を板厚方向として、支持プレート９４のスライド溝９５Ａに対してシート幅方向両側に配置されている。また、スライド溝９５Ａに対してシート幅方向外側に配置された連結プレート１００は、支持プレート９４のシート幅方向両端部のシート下側に配置されている。そして、連結プレート１００の前端が支持フロントプレート９６の後面に溶接等によって接合されると共に、連結プレート１００の上端が支持プレート９４の下面に溶接等によって接合されている。 As shown in FIGS. 5 and 7A, the connecting plate 100 is formed in a substantially long plate shape, and extends in the front-rear direction of the seat from the front end to the rear end of the support plate 94 on the lower side of the support plate 94. Has been extended. 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.
　連結プレート１００の後端部は連結部１００Ａとされており、連結部１００Ａは、支持プレート９４からシート後側へ突出されると共に、側面視でシート後側へ向かうに従いシート下側へ傾斜されている。図７Ｂに示されるように、連結部１００Ａにおける下端部には、シート下側且つシート後側へ開放された切欠き部１００Ｂが形成されている。そして、切欠き部１００Ｂがベースプレート９２の上面及びベースフランジ９２Ｃの前面に溶接等によって結合されている。これにより、連結プレート１００の後端部（連結部１００Ａ）がベースプレート９２によってシート下側且つシート後側から支持される構成になっている。 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 seat and the rear side of the seat is formed at the lower end of the connecting portion 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.
（スライド駆動部１１０について）
　図４及び図６に示されるように、スライド駆動部１１０は、前述した第１ロッド５２と、スライドモータユニット１１６と、第１ロッド５２をＳＣフレーム１４に対してシート前後方向にスライドさせるためのスライド用送りねじ１２２と、を含んで構成されている。すなわち、スライド駆動部１１０が、所謂送りねじ機構として構成されている。さらに、前述した第１ロッド５２が、スライド駆動部１１０及びリンク駆動部５０において、共通に用いられる共用部品として構成されている。 (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.
　第１ロッド５２は、前述したように、リンク機構部２４における左右一対のベースブラケット２６に架け渡されている。この第１ロッド５２には、後述するスライド用送りねじ１２２を第１ロッド５２に連結させるための第２連結ブラケット１１２が設けられており、第２連結ブラケット１１２は、前述した第１連結ブラケット５４に対してシート左側に配置されている。第２連結ブラケット１１２は、シート上側へ開放された略Ｕ字形状に形成されており、第２連結ブラケット１１２の先端部が、第１ロッド５２に固定されている。また、第２連結ブラケット１１２内には、「スライド用支持部材」としてのスライド用ナット１１４が設けられている。スライド用ナット１１４は、第２連結ブラケット１１２にシート幅方向を軸方向として軸支されている。また、スライド用ナット１１４の内側には、シート前後方向に貫通された貫通孔が形成されており、貫通孔の内周部には、雌ネジが形成されている。 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.
　スライドモータユニット１１６は、スライド用ナット１１４のシート後側に配置されると共に、スライド用モータブラケット１２０を介してベースプレート９２の下面に固定されている。このスライドモータユニット１１６は、スライド用モータ１１８を有しており、スライド用モータ１１８は、後述するスライド用送りねじ１２２に連結されている。また、スライド用モータ１１８には、前述した制御部６６（図３参照）が電気的に接続されており、制御部６６の制御によってスライド用モータ１１８が作動する構成になっている。 The slide motor unit 116 is disposed on the rear side of 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.
　スライド用送りねじ１２２は、略丸棒状に形成されて、シート前後方向に延在されている。スライド用送りねじ１２２の後端部（一端部）は、スライドモータユニット１１６内に配置されて、スライドモータユニット１１６に回転可能に支持されると共に、スライド用モータ１１８に連結されている。これにより、スライド用モータ１１８が作動することで、スライド用送りねじ１２２が自身の軸回りに正回転又は逆回転するように構成されている。また、スライド用送りねじ１２２の外周部には、雄ネジが形成されている。そして、スライド用送りねじ１２２の前端側（他端側）の部分が、スライド用ナット１１４に螺合されている。 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.
　これにより、スライド用モータ１１８の作動によってスライド用送りねじ１２２が正回転又は逆回転することで、スライド用ナット１１４（第１ロッド５２）がスライド用送りねじ１２２に対してシート前後方向に相対移動するようになっている。具体的には、スライド用送りねじ１２２が正回転すると、スライド用ナット１１４（第１ロッド５２）がスライド用送りねじ１２２に対してシート前側へ相対移動するように構成されている。一方、スライド用送りねじ１２２が逆回転すると、スライド用ナット１１４（第１ロッド５２）がスライド用送りねじ１２２に対してシート後側へ相対移動するように構成されている。これにより、スライド機構８０の作動によって、第１ブラケット８２（すなわち、オットマン装置２０）が、第２ブラケット９０（すなわち、ＳＣフレーム１４）に対してシート前後方向にスライドするように構成されている。 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.
　また、図３に示されるように、車両用シート１０には、オットマン装置２０及びスライド機構８０を作動させるための操作部６８が設けられており、操作部６８は、制御部６６に電気的に接続されている。この操作部６８は、例えば、オットマン装置２０を使用するときに操作される使用ボタンと、オットマン装置２０を格納させるときに操作される格納ボタンと、を有している。そして、着座乗員が使用ボタンを操作すると、スライド機構８０が作動して、スライド機構８０の作動後にオットマン装置２０のリンク機構２２が作動するようになっている。これにより、オットマン本体７０が、図２の２点鎖線で示す第１格納位置から図２の１点鎖線で示す第２格納位置に配置され、第２格納位置から図３に示す脚載せ位置に配置されるようになっている。一方、着座乗員が格納ボタンを操作すると、オットマン装置２０のリンク機構２２が作動して、リンク機構２２の作動後にスライド機構８０が作動するようになっている。これにより、オットマン本体７０が脚載せ位置から第２格納位置に配置され、第２格納位置から第１格納位置に配置されるようになっている。 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. As a result, the ottoman body 70 is arranged from the first storage position indicated by the two-dot chain line in FIG. 2 to the second storage position indicated by the one-dot chain line in FIG. 2, and from the second storage position to the leg placement position shown in FIG. It is arranged. 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.
　次に本実施の形態の作用及び効果について説明する。 Next, the operation and effect of this embodiment will be described.
　上記のように構成された車両用シート１０では、図１に示すリンク機構２２及びスライド機構８０の作動前において、オットマン本体７０が図２の２点鎖線で示す第１格納位置に配置されている。すなわち、リンク機構２２のリンク機構部２４が折畳まれた状態にされており、スライド機構８０のスライドプレート８４が初期位置に配置されている。そして、オットマン装置２０を使用するときには、着座乗員が使用ボタンを操作する。これにより、制御部６６の制御によって、スライド機構８０が作動し、スライド機構８０の作動後にリンク機構２２を作動して、オットマン本体７０が第１格納位置から図３に示す脚載せ位置に配置される。 In the vehicle seat 10 configured as described above, the ottoman body 70 is disposed at the first storage position indicated by the two-dot chain line in FIG. 2 before the operation of the link mechanism 22 and the slide mechanism 80 illustrated in FIG. . 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. Thus, the slide mechanism 80 is operated by 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 mounting position shown in FIG. The
　具体的には、制御部６６の制御によって図５に示すスライド機構８０のスライド用モータ１１８が作動して、スライド用送りねじ１２２が正回転する。このとき、スライド用送りねじ１２２がスライド用ナット１１４に対して相対回転して、スライド用ナット１１４がスライド用送りねじ１２２に対してシート前側へ相対移動する。そして、スライド用ナット１１４は、第１ロッド５２を介してリンク機構部２４のベースブラケット２６に連結されているため、スライド用ナット１１４がスライド用送りねじ１２２に対してシート前側へ相対移動すると、ベースブラケット２６が、スライド機構８０の第１ブラケット８２（スライドプレート８４）と共に、シート前側へスライドする。これにより、第１ブラケット８２（スライドプレート８４）が初期位置からスライド位置にスライドすると共に、オットマン装置２０（オットマン本体７０）が、図２の矢印Ａ方向側へスライドして、図２の２点鎖線で示す第１格納位置から図２の１点鎖線で示す第２格納位置に配置される。 Specifically, the slide motor 118 of the slide mechanism 80 shown in FIG. 5 is operated by the control of the control unit 66, and the slide feed screw 122 is rotated forward. 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. It arrange | positions from the 1st storage position shown with a dashed line to the 2nd storage position shown with the dashed-dotted line of FIG.
　また、図５及び図６に示されるスライド機構８０の作動後には、制御部６６（図３参照）の制御によってリンク機構２２のリンク用モータ６２が作動して、リンク用送りねじ６４が正回転する。このとき、リンク用送りねじ６４は、リンク用ナット５６から伸長するように、リンク用ナット５６に対して相対移動する。そして、リンク用送りねじ６４の一端部は、リンクモータユニット６０及び第２ロッド５８を介して駆動リンク２８に連結されている。このため、リンク用送りねじ６４がリンク用ナット５６に対して相対移動すると、リンクモータユニット６０及び第２ロッド５８が第１ロッド５２に対してシート前側へ変位すると共に、駆動リンク２８がリンクピンＬＰの軸回り（図２の矢印Ｃ方向側）に回動して、リンク機構部２４が格納状態から展開される。これにより、リンク機構２２が作動して、オットマン本体７０が、図２の矢印Ｂ方向側へ回動して、図２の１点鎖線で示す第２格納位置から脚載せ位置に配置される（図３参照）。したがって、仮に、車両用シート１０において、スライド機構８０を省略した場合と比べて、脚載せ位置をシート前側の位置に設定することができる。 Further, after the slide mechanism 80 shown in FIGS. 5 and 6 is operated, the link motor 62 of the link mechanism 22 is operated under the control of the control unit 66 (see FIG. 3), and the link feed screw 64 is rotated forward. To do. 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 activated, and the ottoman body 70 rotates in the direction of arrow B in FIG. 2 and is placed from the second retracted position shown by the one-dot chain line in FIG. (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.
　一方、オットマン本体７０が脚載せ位置に配置された状態で、オットマン装置２０を格納するときには、着座乗員が格納ボタンを操作する。これにより、制御部６６（図３参照）の制御によって、リンク機構２２が作動し、リンク機構２２の作動後にスライド機構８０が作動して、オットマン本体７０が脚載せ位置から図２の２点鎖線で示す第１格納位置に配置される。 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 (see FIG. 3), the slide mechanism 80 is operated after the link mechanism 22 is operated, and the ottoman main body 70 is moved from the leg placement position to the two-dot chain line in FIG. It arrange | positions at the 1st storage position shown by.
　具体的には、制御部６６の制御によってリンク機構２２のリンク用モータ６２が作動して、リンク用送りねじ６４が逆回転する。このとき、リンク用送りねじ６４は、リンク用ナット５６側へ後退するように、リンク用ナット５６に対して相対移動する。このため、駆動リンク２８がリンクピンＬＰの軸回り（図３の矢印Ｄ方向側）に回動して、リンク機構部２４が折畳まれる。これにより、リンク機構２２が作動して、オットマン本体７０が、図３の矢印Ｅ方向側へ回動して、脚載せ位置から図２の１点鎖線で示す第２格納位置に配置される。 More 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 operates, and the ottoman main body 70 rotates in the direction of arrow E in FIG. 3 and is disposed at the second retracted position indicated by the one-dot chain line in FIG.
　また、リンク機構２２の作動後には、制御部６６（図３参照）の制御によってスライド機構８０のスライド用モータ１１８が作動して、スライド用送りねじ１２２が逆回転する。このとき、スライド用送りねじ１２２がスライド用ナット１１４に対して相対回転して、スライド用ナット１１４がスライド用送りねじ１２２に対してシート後側へ相対移動する。そして、上述のように、スライド用ナット１１４は、第１ロッド５２を介してリンク機構２２のベースブラケット２６に連結されているため、スライド用ナット１１４がスライド用送りねじ１２２に対してシート後側へ相対移動すると、ベースブラケット２６が、スライド機構８０の第１ブラケット８２（スライドプレート８４）と共に、シート後側へスライドする。これにより、第１ブラケット８２（スライドプレート８４）がスライド位置から初期位置にスライドされると共に、オットマン本体７０が、図２の矢印Ｆ方向側へスライドして、図２の１点鎖線で示す第２格納位置から図２の２点鎖線で示す第１格納位置に配置される。 Further, after the link mechanism 22 is operated, the slide motor 118 of the slide mechanism 80 is operated under the control of the control unit 66 (see FIG. 3), and the slide feed screw 122 is rotated 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 body 70 slides in the direction of the arrow F in FIG. It arrange | positions from the 2 storage position to the 1st storage position shown with the dashed-two dotted line of FIG.
　ここで、図１及び図５に示されるように、車両用シート１０では、スライド機構８０が、オットマン装置２０とＳＣフレーム１４との間に設けられており、オットマン装置２０がスライド機構８０によってＳＣフレーム１４にスライド可能に連結している。このため、仮に、スライド機構をオットマン装置２０に設ける場合（具体的には、オットマン本体７０とリンク機構２２との間にスライド機構を設ける場合）と比べて、オットマン装置２０の大型化及び重量増加を抑制し且つ乗り心地性能を確保することができる。 Here, as shown in FIGS. 1 and 5, 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 The frame 14 is slidably connected. Therefore, if the slide mechanism is provided in the ottoman device 20 (specifically, the slide mechanism is provided between the ottoman body 70 and the link mechanism 22), the ottoman device 20 is increased in size and weight. And ride comfort performance can be ensured.
　すなわち、仮に、スライド機構をオットマン装置２０に設ける場合には、例えば、オットマン本体７０をシート前後方向にスライドさせるためのプレートと、当該プレートをスライドさせるための駆動部と、をオットマン本体７０及びリンク機構２２の間に配置させる必要がある。このため、側面から見て、オットマン本体７０の長手方向及び厚み方向において、オットマン本体７０の体格が大きくなる。そして、オットマン本体７０の長手方向においてオットマン本体７０の体格が大きくなると、オットマン本体７０の第１格納位置（図２で示す２点鎖線）及び第２格納位置（図２で示す１点鎖線）において、オットマン本体７０が車両の床部に干渉する虞がある。また、オットマン本体７０の厚み方向においてオットマン本体７０の体格が大きくなると、オットマン本体７０の第１格納位置及び第２格納位置において、シートクッションに対するオットマン本体７０のシート前側への突出量が大きくなる虞がある。 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 when the ottoman body 70 becomes larger in the longitudinal direction of the ottoman body 70, at the first storage position (two-dot chain line shown in FIG. 2) and the second storage position (one-dot chain line shown in FIG. 2) of the ottoman body 70. The ottoman body 70 may interfere with the floor of the vehicle. 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.
　また、仮に、スライド機構をオットマン装置２０に設けると、スライド機構の重量分だけオットマン装置２０の重量が増加する。さらに、この場合には、オットマン本体７０とリンク機構２２との間に、オットマン本体７０をスライドさせるための駆動部を配置させる必要があるため、オットマン装置２０の構造が複雑になる。 Also, 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.
　また、仮に、スライド機構をオットマン本体７０とリンク機構２２との間に設ける場合には、オットマン本体７０自体がスライドするため、スライド機構の有するガタなどが、オットマン本体７０を介して着座乗員の脚部に直接的に伝達される。このため、着座乗員に対する乗り心地性能が悪化する虞がある。 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.
　これに対して、本実施の形態では、スライド機構８０が、オットマン装置２０とＳＣフレーム１４との間に設けられている。このため、仮にスライド機構をオットマン本体７０とリンク機構２２との間に設ける場合と比べて、オットマン本体７０の大型化及び重量増加を抑制することができる。また、オットマン本体７０がスライド機構８０を介さずにリンク機構２２に連結されるため、スライド機構８０の有するガタが、着座乗員に対して直接的に伝達されることを抑制できる。これにより、着座乗員に対する乗り心地性能を確保することができる。以上により、オットマン装置２０の大型化及び重量増加を抑制し且つ乗り心地性能を確保することができる。 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.
　また、オットマン装置２０における左右一対のリンク機構部２４（ベースブラケット２６）が、スライド機構８０の第１ブラケット８２によって連結されている。さらに、ＳＣフレーム１４の左右一対のサイドフレーム１６が、スライド機構８０の第２ブラケット９０によって連結されている。このため、スライド機構８０を活用して、左右一対のリンク機構部２４及びＳＣフレーム１４を補強することができる。 Further, the pair of left and right link mechanism portions 24 (base bracket 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.
　さらに、スライド機構８０では、左右一対のスライド溝９５Ａが、第２ブラケット９０に形成されており、スライド溝９５Ａ内には、第１ブラケット８２に連結されたスライドボルト９８が、スライド可能に設けられている。これにより、第１ブラケット８２と第２ブラケット９０とを簡易な構成でスライド可能に連結することができる。 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.
　また、上述のように、スライド機構８０では、左右一対のリンク機構部２４の間に第１ブラケット８２が設けられており、左右一対のサイドフレーム１６の間に第２ブラケット９０が設けられている。このため、例えば、リンク機構を有する既存のオットマン装置を、スライド機構８０によってＳＣフレーム１４にスライド可能に連結させることができる。 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.
　さらに、スライド機構８０の第２ブラケット９０では、支持プレート９４がベースプレート９２に対してシート前側で且つシート上側に設けられており、支持プレート９４がベースプレート９２に連結プレート１００によって連結されている。このため、スライドプレート８４のシート下側に支持プレート９４を近接して配置させつつ、支持プレート９４とベースプレート９２とを連結プレート１００によって連結することができる。これにより、スライドボルト９８のボルト本体９８Ｂの軸長が極端に長くなることを抑制することができる。その結果、スライドボルト９８がスライド溝９５Ａ内をシート前後方向にスライドするときの、スライド溝９５Ａの内周面に対するスライドボルト９８の抉りを抑制することができる。したがって、第１ブラケット８２（スライドプレート８４）を第２ブラケット９０（支持プレート９４）に対して良好にスライドさせることができる。 Furthermore, in the second bracket 90 of the slide mechanism 80, the support plate 94 is provided on the front side and the upper side of the seat with respect to the base plate 92, and the support plate 94 is connected to the base plate 92 by the connection 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).
　また、連結プレート１００の連結部１００Ａ（後端部）における下端部には、シート下側且つシート後側へ開放された切欠き部１００Ｂが形成されており、切欠き部１００Ｂがベースプレート９２の上面及びベースフランジ９２Ｃの前面に接合されている。これにより、第２ブラケット９０の第１ブラケット８２に対する支持強度を高くすることができると共に、オットマン装置２０に対するスライド機構８０の支持性能を高くすることができる。 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.
　すなわち、オットマン本体７０が脚載せ位置に配置された状態では、リンク機構部２４がシート前側へ展開され、オットマン本体７０が、着座乗員の脚部をシート下側から支持する。すなわち、オットマン装置２０が、ベースブラケット２６を固定端とし、オットマン本体７０を作用点とする片持ち梁のように構成されて、オットマン本体７０にシート下側への荷重が作用する。このため、オットマン装置２０の固定端（ベースブラケット２６）には、シート左側から見て、反時計回りの回転モーメントが作用する。 That is, in a state where the ottoman main body 70 is disposed at the leg mounting 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.
　一方、スライド機構８０の第２ブラケット９０では、支持プレート９４が、ベースプレート９２に対してシート前側及びシート上側に配置されて、連結プレート１００によってベースプレート９２に連結されている。さらに、支持プレート９４には、スライドボルト９８を介して第１ブラケット８２（支持プレート９４）が連結されており、支持プレート９４が第１ブラケット８２（支持プレート９４）をシート下側から支持している。このため、連結プレート１００に、上記と同様に回転モーメントが作用する。そして、上述のように、連結プレート１００の切欠き部１００Ｂ（後端部）がベースプレート９２の上面及びベースフランジ９２Ｃの前面に接合されている。このため、連結プレート１００の回転をベースフランジ９２Ｃがシート後側から受け止めるように作用する。これにより、仮に、連結プレート１００の連結部１００Ａをベースプレート９２の上面のみで接合する場合と比べて、第２ブラケット９０の第１ブラケット８２に対する支持強度を高くすることができる。その結果、オットマン装置２０に対するスライド機構８０の支持性能を高くすることができる。 On the other hand, in the second bracket 90 of the slide mechanism 80, the support plate 94 is disposed on the front side and the upper side of the seat with respect to the base plate 92, and is connected to the base plate 92 by the connecting 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.
　また、スライド機構８０はスライド駆動部１１０を有しており、スライド駆動部１１０が作動することで、第１ブラケット８２が初期位置とスライド位置との間をシート前後方向にスライドする。そして、スライド駆動部１１０は、スライド用モータ１１８の作動によって回転するスライド用送りねじ１２２と、スライド用送りねじ１２２の回転によってスライド用送りねじ１２２の軸方向に移動するスライド用ナット１１４と、含んで構成されており、スライド用ナット１１４が第１ロッド５２に連結されている。すなわち、スライド駆動部１１０は、所謂送りねじ機構として構成されている。これにより、簡易な構成で第１ブラケット８２（すなわち、オットマン装置２０）をシート前後方向に自動でスライドさせることができる。 Also, the slide mechanism 80 has a slide drive unit 110, and 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.
　さらに、スライド機構８０では、支持プレート９４に形成された左右一対のスライド溝９５Ａ内に、それぞれ２個のスライドボルト９８がシート前後方向に離間して配置されている。このため、仮にスライド溝９５Ａ内に１個のスライドボルト９８を配置する構成と比べて、第１ブラケット８２のスライド時における、第１ブラケット８２の支持プレート９４に対する相対回転を抑制することができる。これにより、第１ブラケット８２（オットマン装置２０）が、支持プレート９４（ＳＣフレーム１４）に対してスライドするときの、スライドボルト９８のスライド溝９５Ａの内周面に対する抉りを効果的に抑制することができる。その結果、スライド溝９５Ａ内において、スライドボルト９８をスムースにスライドさせることができる。 Furthermore, 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, respectively, spaced apart in the seat front-rear direction. 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.
　また、図１及び図６に示されるように、スライド機構８０では、シート下側から見て、第１ロッド５２が、シート前側に配置されたスライドボルト９８とシート後側に配置されたスライドボルト９８との間に配置されている。このため、第１ロッド５２をシート前後方向にスライドさせるための駆動力が、前後一対のスライドボルト９８の間において作用する。これにより、第１ブラケット８２のスライド時における、第１ブラケット８２の支持プレート９４に対する相対回転を一層効果的に抑制することができる。したがって、第１ブラケット８２（オットマン装置２０）が、支持プレート９４（ＳＣフレーム１４）に対してスライドするときの、スライドボルト９８のスライド溝９５Ａの内周面に対する抉りを一層効果的に抑制することができる。 As shown in FIGS. 1 and 6, in the slide mechanism 80, as viewed from the lower side of the seat, the first rod 52 has a slide bolt 98 disposed on the front side of the seat and a slide bolt disposed on the rear side of the seat. 98. 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.
　また、第１ロッド５２が、スライド機構８０におけるスライド駆動部１１０と、リンク機構２２におけるリンク駆動部５０と、において、共通に用いられる共用部品として構成されている。このため、部品点数の増加を抑制しつつ、スライド駆動部１１０及びリンク駆動部５０を車両用シート１０に設けることができる。また、第１ロッド５２がスライド駆動部１１０及びリンク駆動部５０における共用部品として構成されているため、車両用シート１０におけるスライド駆動部１１０及びリンク駆動部５０の設置スペースが大きくなることを抑制できる。したがって、スライド駆動部１１０及びリンク駆動部５０において、効率のよい配置構造を実現することができる。 Also, 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.
　なお、本実施の形態では、スライド機構８０が第１ブラケット８２及び第２ブラケット９０を有しており、第１ブラケット８２が第２ブラケット９０に対してスライド可能に連結されているが、スライド機構８０の構成は、これに限らない。例えば、スライド機構８０を、ベースブラケット２６に相対移動不能に設けられたスライダと、サイドフレーム１６に設けられたレールと、によって構成してもよい。この場合には、レールがシート前後方向に延在されると共に、スライダがレールにスライド可能に連結される構成になる。 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.
　また、本実施の形態では、スライド機構８０がスライド駆動部１１０を有しており、スライド駆動部１１０が作動することで、オットマン装置２０がシート前後方向に自動でスライドする構成になっている。これに代えて、スライド機構８０において、スライド駆動部１１０を省略して、オットマン装置２０をシート前後方向に手動でスライドする構成にしてもよい。この場合には、例えば、スライドボルト９８のシート前後方向の移動を阻止するロック機構を、第２ブラケット９０の支持プレート９４に設ける。また、ロック機構によるスライドボルト９８に対するロック状態を解除させる解除レバーを、シート本体１２の側方に設けてもよい。そして、着座乗員が解除レバーを操作して、ロック機構によるスライドボルト９８に対するロック状態を解除させて、オットマン装置２０を手動でスライドさせてもよい。 Further, in the present embodiment, the slide mechanism 80 has 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.
　また、本実施の形態では、制御部６６（図３参照）の制御によって、リンク機構２２及びスライド機構８０が作動して、オットマン本体７０が、第１格納位置（図２で示す２点鎖線）から第２格納位置（図２で示す１点鎖線）に配置され、第２格納位置から脚載せ位置（図３参照）に配置されるようになっている。これに代えて、オットマン本体７０を、第１格納位置と第２格納位置との間の任意の位置に配置させるように、スライド機構８０の作動を制御部６６によって制御してもよい。この場合には、例えば、操作部６８（図３参照）における使用ボタンを、スライド機構８０の作動用の使用ボタンと、リンク機構２２の作動用の使用ボタンとの２つのボタンで構成してもよい。そして、スライド機構８０の作動用の使用ボタンを操作することで、オットマン本体７０を、第１格納位置と第２格納位置との間の任意の位置に配置させるように構成してもよい。 In the present embodiment, the link mechanism 22 and the slide mechanism 80 are operated by the control of the control unit 66 (see FIG. 3), so that the ottoman body 70 is in the first storage position (two-dot chain line shown in FIG. 2). From the second storage position (see FIG. 3) to the second storage position (one-dot chain line shown in FIG. 2). 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 (see FIG. 3) may be composed of two buttons, a use button for operating the slide mechanism 80 and a use button for operating the link mechanism 22. Good. 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.
　また、本実施の形態のスライド機構８０では、第２ブラケット９０の支持プレート９４にスライド溝９５Ａが形成されており、スライド溝９５Ａ内に配置されたスライドボルト９８によって、第１ブラケット８２（スライドプレート８４）が、支持プレート９４にスライド可能に連結されている。これに代えて、第１ブラケット８２のスライドプレート８４にスライド溝９５Ａを形成し、スライド溝９５Ａ内に配置されたスライドボルト９８によって、第１ブラケット８２（スライドプレート８４）を支持プレート９４にスライド可能に連結してもよい。この場合には、第２ブラケット９０の支持プレート９４の下面にウェルドナット８８Ｆ、８８Ｒが固定される構成になる。 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.
　また、本実施の形態のスライド機構８０では、スライドボルト９８がスライド溝９５Ａ内をシート前後方向にスライドする構成になっているが、スライドボルト９８の構成はこれに限らない。例えば、スライドボルト９８に、ボルト本体９８Ｂが挿入される略円筒形状のローラを設けて、当該ローラが、スライド溝９５Ａ内において、ボルト本体９８Ｂの軸回りに回転する構成にしてもよい。これにより、スライド溝９５Ａ内において、スライドボルト９８をよりスムースにスライドさせることができる。 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. For example, the slide bolt 98 may be provided with a substantially cylindrical roller into which the bolt main body 98B is inserted, and the roller rotates around the axis of the bolt main body 98B in the slide groove 95A. Thereby, the slide bolt 98 can be slid more smoothly in the slide groove 95A.
