　しかしながら、上記特許文献２に示されたシート装置では、上述の如く兼用操作レバーの操作方向が、車体幅方向及び上下方向に設定されているため、兼用操作レバーの操作が複雑であり、操作性を向上させる点で改善の余地がある。また、兼用操作レバーを操作するためのスペースを、車体幅方向及び上下方向に確保する必要があるため、スペースの有効利用を図る点でも改善の余地がある。 However, in the seat device shown in Patent Document 2, since the operation direction of the dual operation lever is set in the vehicle body width direction and the vertical direction as described above, the operation of the dual operation lever is complicated and the operability is improved. There is room for improvement in terms of improving Further, since it is necessary to secure a space for operating the dual operation lever in the vehicle body width direction and the vertical direction, there is room for improvement in terms of effective use of the space.
　本発明は上記事実を考慮し、１つの操作部材によって複数の被調整機構を個別に調整し又は調整可能な状態にすることができると共に、操作性の向上とスペースの有効利用を図ることができる車両用シートを得ることを目的としている。 In consideration of the above facts, the present invention can individually adjust or adjust a plurality of mechanisms to be adjusted by one operating member, and can improve operability and effectively use a space. The purpose is to obtain a vehicle seat.
　本発明の第１の態様の車両用シートは、それぞれがシート本体に設けられ、操作力が伝達されることにより調整され又は調整可能な状態とされる複数の被調整機構と、前記シート本体に対して回転可能に取り付けられ、回転範囲の一側及び他側へ操作可能とされた操作部材と、前記操作部材に設けられ、自ら操作されることにより前記操作部材に対して第１位置から第２位置へと移動される切替部材と、前記操作部材に対して一体回転可能に設けられると共に、前記切替部材の移動に伴って前記操作部材の回転軸線方向に移動される移動クラッチ部材と、１又は２つの前記被調整機構と連結され、前記切替部材が前記第１位置及び前記第２位置の何れか一方に位置する状態では前記移動クラッチ部材と一体回転可能に係合することにより、前記操作部材の操作力を前記１又は２つの被調整機構に伝達可能とされる第１クラッチ部材と、前記１又は２つの被調整機構とは別の１又は２つの前記被調整機構と連結され、前記切替部材が前記第１位置及び前記第２位置の何れか他方に位置する状態では前記移動クラッチ部材と一体回転可能に係合することにより、前記操作部材の操作力を前記別の１又は２つの被調整機構に伝達可能とされる第２クラッチ部材と、を備えている。 The vehicle seat according to the first aspect of the present invention is provided with a plurality of adjustable mechanisms, each of which is provided on the seat main body and adjusted or adjustable by transmission of an operating force, and the seat main body. An operation member that is rotatably attached to the rotation range and that can be operated to one side and the other side of the rotation range, and is provided on the operation member, and is operated from the first position to the operation member by itself. A switching member that is moved to two positions, a moving clutch member that is provided so as to be integrally rotatable with respect to the operating member, and that is moved in the rotational axis direction of the operating member as the switching member is moved; Or, it is connected to the two mechanisms to be adjusted, and in a state where the switching member is located in either one of the first position and the second position, by engaging with the moving clutch member so as to be integrally rotatable, The first clutch member capable of transmitting the operation force of the operation member to the one or two adjusted mechanisms and the one or two adjusted mechanisms different from the one or two adjusted mechanisms are coupled. In the state where the switching member is located at either one of the first position and the second position, the operating force of the operating member is changed to the other one or And a second clutch member capable of transmitting to the two adjusted mechanisms.
　第１の態様では、操作部材がシート本体に回転可能に取り付けられており、当該操作部材には切替部材が設けられている。この切替部材が第１位置及び第２位置の何れか一方に位置する状態では、操作部材に対して一体回転可能に設けられた移動クラッチ部材と第１クラッチ部材とが一体回転可能に係合する。この状態で操作部材が回転範囲の一側及び他側へ操作されると、第１クラッチ部材に連結された１又は２つの被調整機構に操作力が伝達されることにより、当該１又は２つの被調整機構が調整され又は調整可能な状態（例えば、ロック解除状態）とされる。一方、切替部材が第１位置及び第２位置の何れか他方に位置する状態では、移動クラッチ部材と第２クラッチ部材とが一体回転可能に係合する。この状態で操作部材が一側及び他側へ操作されると、第２クラッチ部材に連結された別の１又は２つの被調整機構に操作力が伝達されることにより、当該別の１又は２つの被調整機構が調整され又は調整可能な状態とされる。このように、本発明によれば、１つの操作部材によって複数の被調整機構を調整し又は調整可能な状態にすることができる。しかも、操作部材の操作方向が回転範囲の一側及び他側とされており、単純であるため、操作性の向上及びスペースの有効利用を図ることができる。 In the first aspect, the operation member is rotatably attached to the seat body, and the operation member is provided with a switching member. In a state in which the switching member is located at either the first position or the second position, the moving clutch member and the first clutch member that are provided so as to be integrally rotatable with respect to the operation member are engaged so as to be integrally rotatable. . In this state, when the operating member is operated to one side and the other side of the rotation range, the operating force is transmitted to one or two adjusted mechanisms connected to the first clutch member, whereby the one or two The adjusted mechanism is adjusted or can be adjusted (for example, unlocked state). On the other hand, in a state where the switching member is located at the other of the first position and the second position, the moving clutch member and the second clutch member are engaged so as to be integrally rotatable. When the operating member is operated to one side and the other side in this state, the operating force is transmitted to another one or two adjusted mechanisms connected to the second clutch member, and thus the other one or two The two adjustable mechanisms are adjusted or can be adjusted. As described above, according to the present invention, it is possible to adjust or adjust a plurality of mechanisms to be adjusted by one operation member. In addition, since the operation direction of the operation member is one side and the other side of the rotation range and is simple, the operability can be improved and the space can be effectively used.
　さらに、第１の態様では、操作部材と一体回転可能に設けられた移動クラッチ部材が操作部材の回転軸線方向に移動されて第１クラッチ部材又は第２クラッチ部材と係合する。このため、例えば移動クラッチ部材が操作部材の回転半径方向（回転軸線と直交する方向）に移動されて第１クラッチ部材又は第２クラッチ部材と係合する構成と比較して、移動クラッチ部材と第１クラッチ部材との係合面、及び移動クラッチ部材と第２クラッチ部材との係合面を広く設定することができる。これにより、操作部材の操作力（トルク）を上記広い係合面に分散することができるので、上記各クラッチ部材の伝達許容トルクを向上させることができる。その結果、例えば上記各クラッチ部材を樹脂材料によって形成した場合でも、上記各クラッチ部材の伝達許容トルクを所望の値に設定することが可能になるので、上記各クラッチ部材の軽量化を図ることが可能になる。 Furthermore, in the first aspect, the moving clutch member provided so as to rotate integrally with the operation member is moved in the rotation axis direction of the operation member and engaged with the first clutch member or the second clutch member. For this reason, for example, the moving clutch member and the first clutch member are compared with the first clutch member or the second clutch member as compared with the configuration in which the moving clutch member is moved in the rotational radius direction (direction orthogonal to the rotation axis) of the operation member. The engagement surface with the first clutch member and the engagement surface between the moving clutch member and the second clutch member can be set widely. As a result, the operating force (torque) of the operating member can be distributed over the wide engagement surface, so that the transmission allowable torque of each clutch member can be improved. As a result, for example, even when each clutch member is formed of a resin material, the transmission allowable torque of each clutch member can be set to a desired value, so that the weight of each clutch member can be reduced. It becomes possible.
　本発明の第２の態様の車両用シートは、第１の態様において、前記第１クラッチ部材の前記移動クラッチ部材側には、前記第１クラッチ部材の回転方向に並んだ複数の歯によって構成された第１噛合部が形成され、前記第２クラッチ部材の前記移動クラッチ部材側には、前記第２クラッチ部材の回転方向に並んだ複数の歯によって構成された第２噛合部が形成され、前記移動クラッチ部材の前記第１クラッチ部材側には、前記移動クラッチ部材の回転方向に並んだ複数の歯によって構成され、前記第１噛合部と噛合い可能とされた一側噛合部が形成され、前記移動クラッチ部材の前記第２クラッチ部材側には、前記移動クラッチ部材の回転方向に並んだ複数の歯によって構成され、前記第２噛合部と噛合い可能とされた他側噛合部が形成されている。 According to a second aspect of the present invention, in the first aspect, the vehicle seat includes a plurality of teeth arranged in the rotational direction of the first clutch member on the moving clutch member side of the first clutch member. A first meshing portion is formed, and on the moving clutch member side of the second clutch member, a second meshing portion constituted by a plurality of teeth arranged in the rotation direction of the second clutch member is formed, On the first clutch member side of the moving clutch member, a one-side meshing portion is formed which is configured by a plurality of teeth arranged in the rotational direction of the moving clutch member, and can mesh with the first meshing portion, The second clutch member side of the moving clutch member is formed with a second meshing portion that is configured by a plurality of teeth arranged in the rotational direction of the movable clutch member and that can mesh with the second meshing portion. To have.
　第２の態様によれば、移動クラッチ部材が第１クラッチ部材と係合した状態では、移動クラッチ部材の一側噛合部が第１クラッチ部材の第１噛合部と噛み合う。同様に、移動クラッチ部材が第２クラッチ部材と係合した状態では、移動クラッチ部材の他側噛合部が第２クラッチ部材の第２噛合部と噛み合う。ここで、上記一側噛合部、他側噛合部、第１噛合部及び第２噛合部は、上記各クラッチ部材の回転方向に並んだ複数の歯によって構成されているため、一側噛合部と第１噛合部との噛合い状態において両者の間で伝達される操作部材の操作力、及び他側噛合部と第２噛合部との噛合い状態において両者の間で伝達される操作部材の操作力を、上記各噛合部における複数の歯に分散することができる。これにより、１歯当りの伝達トルクを低減することができる。このため、例えば上記各クラッチ部材を樹脂材料によって形成した場合でも、操作部材の操作力を上記各クラッチ部材を介して良好に伝達することができる。 According to the second aspect, when the moving clutch member is engaged with the first clutch member, the one-side meshing portion of the moving clutch member meshes with the first meshing portion of the first clutch member. Similarly, when the moving clutch member is engaged with the second clutch member, the other meshing portion of the moving clutch member meshes with the second meshing portion of the second clutch member. Here, since the one-side meshing portion, the other-side meshing portion, the first meshing portion, and the second meshing portion are configured by a plurality of teeth arranged in the rotation direction of each clutch member, The operating force of the operating member transmitted between both in the meshed state with the first meshing portion, and the operation of the operating member transmitted between both in the meshed state of the other meshing portion and the second meshing portion The force can be distributed to a plurality of teeth at each meshing portion. Thereby, the transmission torque per tooth can be reduced. For this reason, for example, even when each clutch member is formed of a resin material, the operation force of the operation member can be transmitted satisfactorily through each clutch member.
　本発明の第３の態様の車両用シートは、第２の態様において、前記各歯は、前記各クラッチ部材の回転半径方向から見て先端側が先細状に形成されている。 In the vehicle seat according to the third aspect of the present invention, in the second aspect, each tooth is formed such that its tip side is tapered as viewed from the rotational radius direction of each clutch member.
　第３の態様では、移動クラッチ部材の一側噛合部が第１クラッチ部材の第１噛合部と噛み合う際に、一側噛合部の複数の歯と第１噛合部の複数の歯とが移動クラッチ部材及び第１クラッチ部材の回転方向にずれている場合には、これらの歯における先細状の先端側が互いに摺接する。これにより、上記ずれが解消するように移動クラッチ部材及び第１クラッチ部材のうちの少なくとも一方を回転させることができる。同様に、移動クラッチ部材の他側噛合部が第２クラッチ部材の第２噛合部と噛み合う際に、他側噛合部の複数の歯と第２噛合部の複数の歯とが移動クラッチ部材及び第２クラッチ部材の回転方向にずれている場合には、これらの歯における先細状の先端側が互いに摺接する。これにより、上記ずれが解消するように移動クラッチ部材及び第２クラッチ部材のうちの少なくとも一方を回転させることができる。したがって、切替部材の操作に伴う移動クラッチ部材の移動、すなわちクラッチ切替動作を円滑なものにすることができる。なお、第３の態様に記載の先細状は、上述の如き効果が得られるものであればよく、当該先細状には、三角形状、テーパー状、半円状などが含まれる。 In the third aspect, when the one-side meshing portion of the moving clutch member meshes with the first meshing portion of the first clutch member, the plurality of teeth of the one-side meshing portion and the plurality of teeth of the first meshing portion are moved to the moving clutch. When the members and the first clutch member are displaced in the rotational direction, the tapered tip ends of these teeth are in sliding contact with each other. Thereby, at least one of the moving clutch member and the first clutch member can be rotated so as to eliminate the above-described deviation. Similarly, when the other meshing portion of the moving clutch member meshes with the second meshing portion of the second clutch member, the plurality of teeth of the other meshing portion and the plurality of teeth of the second meshing portion are connected to the moving clutch member and the first meshing portion. When the two clutch members are displaced in the rotation direction, the tapered tip ends of these teeth are in sliding contact with each other. Thereby, at least one of the moving clutch member and the second clutch member can be rotated so as to eliminate the above-described deviation. Therefore, the movement of the moving clutch member accompanying the operation of the switching member, that is, the clutch switching operation can be made smooth. In addition, the taper shape described in the third aspect is not particularly limited as long as the above-described effects can be obtained, and the taper shape includes a triangular shape, a tapered shape, a semicircular shape, and the like.
　本発明の第４の態様の車両用シートは、第２の態様又は第３の態様において、前記移動クラッチ部材は、前記切替部材が前記第１位置に位置する状態で前記一側噛合部が前記第１クラッチ部材の前記第１噛合部と噛合うと共に、前記一側噛合部及び前記第１噛合部は、前記第１クラッチ部材が前記移動クラッチ部材に対して特定の角度に位置する状態でしか噛合わないように形状が設定されている。 The vehicle seat according to a fourth aspect of the present invention is the vehicle seat according to the second aspect or the third aspect, wherein the moving clutch member is configured such that the one-side meshing portion is in the state where the switching member is located at the first position. The one side meshing portion and the first meshing portion are engaged with the first meshing portion of the first clutch member only when the first clutch member is positioned at a specific angle with respect to the moving clutch member. The shape is set so as not to mesh.
　第４の態様によれば、操作部材に設けられた切替部材が第１位置に位置する状態（例えば、操作部材の非操作状態）では、操作部材に対して一体回転可能とされた移動クラッチ部材の一側噛合部と、第１の被調節機構及び第２の被調節機構が連結された第１クラッチ部材の第１噛合部とが噛合う。このため、移動クラッチ部材に対する第１クラッチ部材の係合角度（一側噛合部と第１噛合部との噛合角度）は、第１の被調節機構及び第２の被調節機構の誤動作防止の観点から、これらの機構との関係で特定の角度に限定されることが好ましい。ここで、第４の態様では、移動クラッチ部材の一側噛合部及び第１クラッチ部材の第１噛合部は、第１クラッチ部材が移動クラッチ部材に対して特定の角度に位置する状態でしか噛合わないように形状が設定されている。これにより、移動クラッチ部材に対する第１クラッチ部材の噛合角度を特定の角度に限定することができるので、上記各機関の誤動作を防止することができる。また、移動クラッチ部材に対して第１クラッチ部材を組み付ける際に誤組付を防止することができる。 According to the fourth aspect, in the state where the switching member provided in the operation member is located at the first position (for example, the non-operation state of the operation member), the moving clutch member that is integrally rotatable with respect to the operation member 1 side meshing part and the 1st meshing part of the 1st clutch member to which the 1st to-be-adjusted mechanism and the 2nd to-be-adjusted mechanism were connected mesh | engage. For this reason, the engagement angle of the first clutch member with respect to the moving clutch member (the engagement angle between the one-side engagement portion and the first engagement portion) is set to prevent malfunction of the first adjusted mechanism and the second adjusted mechanism. Therefore, it is preferable that the angle is limited to a specific angle in relation to these mechanisms. Here, in the fourth aspect, the one-side engaging portion of the moving clutch member and the first engaging portion of the first clutch member are engaged only in a state where the first clutch member is positioned at a specific angle with respect to the moving clutch member. The shape is set so that it does not fit. Thereby, since the meshing angle of the first clutch member with respect to the moving clutch member can be limited to a specific angle, malfunction of each engine can be prevented. Further, erroneous assembly can be prevented when the first clutch member is assembled to the moving clutch member.
　本発明の第５の態様の車両用シートは、第１～第４の態様の何れか１つの態様において、前記操作部材が前記一側と前記他側との中間に設定された中立位置に復帰するように前記操作部材を付勢する専用の付勢部材を有している。 The vehicle seat according to a fifth aspect of the present invention is the vehicle seat according to any one of the first to fourth aspects, wherein the operation member is returned to a neutral position set between the one side and the other side. As described above, a dedicated urging member for urging the operation member is provided.
　第５の態様では、操作部材を回転範囲の一側と他側との中間に設定された中立位置へと付勢する専用の付勢部材を有している。これにより、一側又は他側へ操作された操作部材が中立位置に復帰する際には操作力を要しないようにすることができるので、操作部材の操作を容易なものにすることができる。 In the fifth aspect, there is a dedicated urging member that urges the operating member to a neutral position set in the middle between one side and the other side of the rotation range. Thereby, when the operation member operated to the one side or the other side returns to the neutral position, it is possible to prevent an operation force from being required, so that the operation member can be easily operated.
　本発明の第６の態様の車両用シートは、第５の態様において、前記シート本体に対して変位不能に設けられ、前記切替部材が前記第１位置と前記第２位置との間に位置する状態では、前記切替部材と係合することにより、前記中立位置からの前記操作部材の回転を規制する回転規制部を有している。 According to a sixth aspect of the present invention, in the fifth aspect, the vehicle seat is provided so as not to be displaceable with respect to the seat body, and the switching member is located between the first position and the second position. In the state, it has a rotation restricting portion that restricts rotation of the operation member from the neutral position by engaging with the switching member.
　第６の態様によれば、操作部材に取り付けられた切替部材が第１位置と第２位置との間に位置する状態では、シート本体に対して変位不能に設けられた移動規制部が切替部材と係合することにより、中立位置からの操作部材の回転が規制される。このため、切替部材が第１位置と第２位置との間に位置する状態、すなわち操作部材が移動クラッチ部材を介して第１クラッチ部材及び第２クラッチ部材の両方と連結される可能性がある状態で、操作部材が回転されることを防止できる。これにより、誤作動が生じることを回避できる。 According to the sixth aspect, in a state where the switching member attached to the operation member is located between the first position and the second position, the movement restricting portion provided so as not to be displaceable with respect to the seat body is the switching member. , The rotation of the operation member from the neutral position is restricted. For this reason, there is a possibility that the switching member is located between the first position and the second position, that is, the operation member is connected to both the first clutch member and the second clutch member via the moving clutch member. In this state, the operation member can be prevented from rotating. Thereby, it can avoid that malfunctioning arises.
　以上説明したように、本発明に係る車両用シートでは、１つの操作部材によって複数の被調整機構を個別に調整し又は調整可能な状態にすることができると共に、操作性の向上とスペースの有効利用を図ることができる。 As described above, in the vehicle seat according to the present invention, it is possible to individually adjust or adjust a plurality of adjusted mechanisms with one operating member, and to improve operability and effective space. Can be used.

　シートクッションフレーム１６の後端部とシートバックフレーム１８の下端部とは、角度調整機構としてのリクライニング機構２０（第１の被調整機構）を介して連結されている。このリクライニング機構２０は、従来周知のものであり、ロック解除レバー２２がロック解除方向（図１の矢印Ａ方向）に回転されることによりロックが解除され、シートクッションフレーム１６に対するシートバックフレーム１８の相対角度（リクライニング角度）を多段階に調整可能となる。 The rear end portion of the seat cushion frame 16 and the lower end portion of the seat back frame 18 are connected via a reclining mechanism 20 (first adjusted mechanism) as an angle adjusting mechanism. The reclining mechanism 20 is well known in the art, and is unlocked when the lock release lever 22 is rotated in the lock release direction (the direction of arrow A in FIG. 1), so that the seat back frame 18 moves relative to the seat cushion frame 16. The relative angle (reclining angle) can be adjusted in multiple stages.
　また、シートクッションフレーム１６とシートバックフレーム１８との間には、シートバックフレーム１８を前傾方向へ付勢するリターンスプリング２４が掛け渡されている。このため、リクライニング機構２０のロック解除状態でシートバックフレーム１８に負荷を掛けない場合には、シートバックフレーム１８がシートクッションフレーム１６に対して所定位置まで前傾するようになっている。一方、リクライニング機構２０のロック解除状態においてシートバックフレーム１８に所定値以上の後ろ向き荷重を作用させると、シートバックフレーム１８がシートクッションフレーム１６に対して後傾するようになっている。そして、任意の傾斜角でロック解除レバー２２の操作力を解除すると、リクライニング機構２０がロック状態に復帰し、シートバックフレーム１８が傾倒不能に拘束される。 Further, a return spring 24 is laid between the seat cushion frame 16 and the seat back frame 18 to urge the seat back frame 18 in the forward tilt direction. Therefore, when no load is applied to the seat back frame 18 in the unlocked state of the reclining mechanism 20, the seat back frame 18 tilts forward to a predetermined position with respect to the seat cushion frame 16. On the other hand, when a backward load of a predetermined value or more is applied to the seat back frame 18 in the unlocked state of the reclining mechanism 20, the seat back frame 18 tilts backward with respect to the seat cushion frame 16. When the operation force of the lock release lever 22 is released at an arbitrary inclination angle, the reclining mechanism 20 returns to the locked state, and the seat back frame 18 is restrained from being tilted.
　また、シートクッションフレーム１６は、高さ調整機構としてのリフタ機構２６（第３の被調整機構）を介してロアフレーム２８に連結されている。このリフタ機構２６は、従来周知のものであり、シートクッションフレーム１６とロアフレーム２８とに回転自在に連結された前側リンク３０と後側リンク３２（図１以外では図示省略）とを備えている。これらの前側リンク３０及び後側リンク３２は、シートクッションフレーム１６及びロアフレーム２８と共に４節リンクを構成している。 The seat cushion frame 16 is connected to the lower frame 28 via a lifter mechanism 26 (third adjusted mechanism) as a height adjusting mechanism. The lifter mechanism 26 is a well-known one and includes a front link 30 and a rear link 32 (not shown except for FIG. 1) that are rotatably connected to the seat cushion frame 16 and the lower frame 28. . The front link 30 and the rear link 32 form a four-bar link together with the seat cushion frame 16 and the lower frame 28.
　また、リフタ機構２６は、従来周知のポンプ式リフタ装置３４（図３、図５、図６参照）を備えている。このポンプ式リフタ装置３４は、シートクッションフレーム１６における車両幅方向外側の側面に取り付けられており、図５及び図６に示されるように、軸線方向がシート幅方向に沿った入力軸３６を備えている。この入力軸３６が回転されると、当該入力軸３６の回転力がシートクッションフレーム１６に取り付けられたピニオン３３及びリフタギヤ３５（図５及び図６参照）を介して後側リンク３２に伝達されるようになっている。これにより、後側リンク３２及び前側リンク３０が回動して、ロアフレーム２８に対するシートクッションフレーム１６の配置高さが調整されるようになっている。この場合、入力軸３６が図３及び図４の矢印Ｂ方向へ回転されると、シートクッションフレーム１６が上方へ変位し、入力軸３６が図３及び図４の矢印Ｃ方向へ回転されると、シートクッションフレーム１６が下方へ変位する。 The lifter mechanism 26 includes a conventionally known pump type lifter device 34 (see FIGS. 3, 5, and 6). The pump type lifter device 34 is attached to the outer side surface of the seat cushion frame 16 in the vehicle width direction, and as shown in FIGS. 5 and 6, includes an input shaft 36 whose axial direction is along the seat width direction. ing. When the input shaft 36 is rotated, the rotational force of the input shaft 36 is transmitted to the rear link 32 via the pinion 33 and the lifter gear 35 (see FIGS. 5 and 6) attached to the seat cushion frame 16. It is like that. Thereby, the rear link 32 and the front link 30 are rotated, and the arrangement height of the seat cushion frame 16 with respect to the lower frame 28 is adjusted. In this case, when the input shaft 36 is rotated in the direction of arrow B in FIGS. 3 and 4, the seat cushion frame 16 is displaced upward, and when the input shaft 36 is rotated in the direction of arrow C in FIGS. 3 and 4. The seat cushion frame 16 is displaced downward.
　図１及び図２に示されるように、ロアフレーム２８の下方には、前後位置調整機構としてのスライド機構３８（第２の被調整機構）の構成部材であるスライドレール４０が配置されている。このスライド機構３８は、従来周知のものであり、ロアフレーム２８の下端部に固定されたアッパレール４２が、車体フロアに固定されたロアレール４４によってシート前後方向にスライド可能に支持されている。このスライド機構３８には、ロアレール４４に対するアッパレール４２のスライドをロック（規制）する図示しないロック機構が設けられている。このロック機構は、ロアフレーム２８に軸支されたロック解除レバー４６がロック解除方向（図１の矢印Ｄ方向）に回転されることにより、上記ロックを解除するようになっている。これにより、ロアレール４４に対するアッパレール４２のスライド、すなわち車体フロアに対する本車両用シート１０の前後位置調整が可能な状態になる。 As shown in FIGS. 1 and 2, a slide rail 40, which is a constituent member of a slide mechanism 38 (second adjusted mechanism) as a front / rear position adjusting mechanism, is disposed below the lower frame 28. The slide mechanism 38 is well known in the art, and an upper rail 42 fixed to the lower end portion of the lower frame 28 is supported by a lower rail 44 fixed to the vehicle body floor so as to be slidable in the front-rear direction of the seat. The slide mechanism 38 is provided with a lock mechanism (not shown) that locks (regulates) the slide of the upper rail 42 with respect to the lower rail 44. The lock mechanism is configured to release the lock when the lock release lever 46 pivotally supported by the lower frame 28 is rotated in the lock release direction (the direction of arrow D in FIG. 1). As a result, the upper rail 42 slides with respect to the lower rail 44, that is, the front and rear position of the vehicle seat 10 with respect to the vehicle body floor can be adjusted.
　次に、シート調整装置１４について説明する。
　図３～図６に示されるように、シート調整装置１４は、噛合いクラッチ機構４８を備えている。この噛合いクラッチ機構４８は、前述したポンプ式リフタ装置３４のシート幅方向外側に配設されており、プレート５０を有している。プレート５０は、金属材料によって円板状に形成されており、ポンプ式リフタ装置３４の入力軸３６と同軸的に配置されている。このプレート５０の中央部におけるポンプ式リフタ装置３４側の面には、図示しない凹状の被嵌合部が形成されており、当該被嵌合部には、ポンプ式リフタ装置３４の入力軸３６に設けられた凸状の嵌合部５２が嵌合している。上記被嵌合部及び嵌合部５２は、シート幅方向から見て三又状に形成されており、これにより、入力軸３６に対するプレート５０の相対回転が規制されている。 Next, the sheet adjustment device 14 will be described.
As shown in FIGS. 3 to 6, the sheet adjusting device 14 includes a meshing clutch mechanism 48. The mesh clutch mechanism 48 is disposed on the outer side in the seat width direction of the pump type lifter device 34 described above, and has a plate 50. The plate 50 is formed in a disk shape from a metal material, and is arranged coaxially with the input shaft 36 of the pump lifter device 34. A concave fitting portion (not shown) is formed on the surface of the central portion of the plate 50 on the pump lifter device 34 side, and the fitting portion is connected to the input shaft 36 of the pump lifter device 34. The provided convex fitting part 52 is fitted. The fitting portion and the fitting portion 52 are formed in a three-pronged shape when viewed from the sheet width direction, and thereby the relative rotation of the plate 50 with respect to the input shaft 36 is restricted.
　プレート５０を介してポンプ式リフタ装置３４とは反対側には、噛合いクラッチ機構４８の構成部材である第２クラッチ部材５４（内側クラッチ部材）が配置されている。この第２クラッチ部材５４は、樹脂材料によって円板状に形成されており、ポンプ式リフタ装置３４の入力軸３６と同軸的に配置されている。この第２クラッチ部材５４の外周部におけるプレート５０側の面には、プレート５０側へ突出した複数（ここでは３つ）の凸部５６が設けられている。これらの凸部５６は、第２クラッチ部材５４の周方向において等間隔に並んで配置されており、プレート５０の外周部に形成された複数（ここでは３つ）の切欠部５９に嵌合している。これにより、プレート５０に対する第２クラッチ部材５４の相対回転が規制されており、第２クラッチ部材５４は、プレート５０を介して入力軸３６と一体回転可能に連結されている。また、第２クラッチ部材５４の外周部におけるプレート５０とは反対側の面には、第２噛合部５８（クラッチ歯）が形成されている。この第２噛合部５８は、第２クラッチ部材５４の周方向（回転方向）に等間隔に並んだ複数の歯６１（図７参照）によって構成されており、第２クラッチ部材５４の外周部の全周にわたって設けられている。 A second clutch member 54 (inner clutch member) that is a constituent member of the mesh clutch mechanism 48 is disposed on the opposite side of the pump lifter device 34 via the plate 50. The second clutch member 54 is formed in a disk shape from a resin material, and is disposed coaxially with the input shaft 36 of the pump lifter device 34. A plurality of (here, three) convex portions 56 projecting toward the plate 50 are provided on the surface of the second clutch member 54 on the plate 50 side at the outer peripheral portion. These convex portions 56 are arranged at equal intervals in the circumferential direction of the second clutch member 54, and fit into a plurality of (here, three) cutout portions 59 formed on the outer peripheral portion of the plate 50. ing. Accordingly, the relative rotation of the second clutch member 54 with respect to the plate 50 is restricted, and the second clutch member 54 is coupled to the input shaft 36 via the plate 50 so as to be integrally rotatable. A second meshing portion 58 (clutch teeth) is formed on the surface of the outer peripheral portion of the second clutch member 54 on the side opposite to the plate 50. The second meshing portion 58 is composed of a plurality of teeth 61 (see FIG. 7) arranged at equal intervals in the circumferential direction (rotating direction) of the second clutch member 54, and It is provided all around.
　第２クラッチ部材５４を介してプレート５０とは反対側には、噛合いクラッチ機構４８の構成部材であるケース６０が配置されている。このケース６０は、樹脂材料によってシート幅方向内側が開口した有底円筒状に形成されており、ポンプ式リフタ装置３４の入力軸３６と同軸的に配置されている。図５及び図６に示されるように、ケース６０の底壁６２の中央部には、第２クラッチ部材５４側へ突出した支持部６４が一体かつ同軸的に設けられている。この支持部６４は、シート幅方向内側が開口した有底円筒状に形成されており、底壁部分には円形の貫通孔が形成されている。この貫通孔には、円筒状のカラー６６が同軸的に挿入されている。 A case 60, which is a constituent member of the mesh clutch mechanism 48, is disposed on the opposite side of the plate 50 via the second clutch member 54. The case 60 is formed of a resin material in a bottomed cylindrical shape that is open on the inner side in the sheet width direction, and is disposed coaxially with the input shaft 36 of the pump lifter device 34. As shown in FIGS. 5 and 6, a support portion 64 protruding toward the second clutch member 54 is integrally and coaxially provided at the center portion of the bottom wall 62 of the case 60. The support portion 64 is formed in a bottomed cylindrical shape having an opening on the inner side in the sheet width direction, and a circular through hole is formed in the bottom wall portion. A cylindrical collar 66 is coaxially inserted into the through hole.

In addition, one end portion in the axial direction of the collar 66 is in contact with one end surface in the axial direction of the input shaft 36 (end portion on the outer side in the sheet width direction). Bolts 68 are inserted into the collar 66 from the outside in the sheet width direction, and the front end side of the bolts 68 is screwed into a female thread portion formed on the input shaft 36. As a result, the collar 66 is fastened and fixed to the input shaft 36, and the movement of the support portion 64 (that is, the case 60) with respect to the input shaft 36 to the outside in the seat width direction is restricted by the head of the bolt 68. Further, the center side of the second clutch member 54 and the center side of the plate 50 are sandwiched between the bottom wall of the support portion 64 and the input shaft 36. Thereby, the movement of the plate 50 and the second clutch member 54 in the axial direction with respect to the input shaft 36 is restricted, and the movement of the case 60 in the seat width direction with respect to the input shaft 36 is restricted. However, the length of the collar 66 is set so that the relative rotation of the case 60 with respect to the input shaft 36 is not restricted by the bolt 68, and the case 60 is rotatable relative to the input shaft 36.
　このケース６０の底壁６２におけるシート幅方向外側の面には、シート幅方向外側へ突出した複数（ここでは３つ）の筒状部７０が設けられている。これらの筒状部７０は、円筒状に形成され、ケース６０の周方向に等間隔に並んで配置されており、これらの筒状部７０の内側を介してケース６０の底壁６２の一側（シート幅方向内側）と他側（シート幅方向外側）とが連通している。これらの筒状部７０は、後述する移動クラッチ部材７２に設けられた複数の棒状部８０に対応している。また、ケース６０の底壁６２における上記複数の筒状部７０の間には、図示しない金属製のナットがインサート成形によって埋め込まれている。これらのナットは、後述する操作レバー１１８に対応している。 A plurality (three in this case) of cylindrical portions 70 projecting outward in the sheet width direction are provided on the outer surface of the bottom wall 62 of the case 60 in the sheet width direction. The cylindrical portions 70 are formed in a cylindrical shape and are arranged at equal intervals in the circumferential direction of the case 60. One side of the bottom wall 62 of the case 60 is disposed inside the cylindrical portions 70. The inside (sheet width direction inner side) and the other side (sheet width direction outer side) communicate. These cylindrical portions 70 correspond to a plurality of rod-like portions 80 provided on the moving clutch member 72 described later. A metal nut (not shown) is embedded between the plurality of cylindrical portions 70 in the bottom wall 62 of the case 60 by insert molding. These nuts correspond to an operation lever 118 described later.
　上述したケース６０の内側には、噛合いクラッチ機構４８の構成部材である移動クラッチ部材７２が収容されている。移動クラッチ部材７２は、樹脂材料によって軸線方向寸法が短い円筒状に形成されており、内側にケース６０の支持部６４が挿入されている。支持部６４の外周面及び移動クラッチ部材７２の内周面には、互いに係合する外周側スプライン部７４（図５参照）及び内周側スプライン部７６（図３及び図４参照）がそれぞれ形成されている。つまり、支持部６４の外周面に軸線方向に沿って形成された断面凹凸状の外周側スプライン部７４と、移動クラッチ部材７２の内周面に軸線方向に沿って形成された断面凹凸状の内周側スプライン部７６とが摺動可能に係合することにより、移動クラッチ部材７２がケース６０に対して一体回転可能でかつ軸線方向に移動自在に装着されている。 A moving clutch member 72 that is a constituent member of the meshing clutch mechanism 48 is accommodated inside the case 60 described above. The moving clutch member 72 is formed in a cylindrical shape having a short axial dimension by a resin material, and the support portion 64 of the case 60 is inserted inside. An outer peripheral side spline portion 74 (see FIG. 5) and an inner peripheral side spline portion 76 (see FIGS. 3 and 4) that engage with each other are formed on the outer peripheral surface of the support portion 64 and the inner peripheral surface of the moving clutch member 72, respectively.

That is, the outer peripheral side spline portion 74 having an uneven cross section formed along the axial direction on the outer peripheral surface of the support portion 64 and the inner surface having an uneven cross section formed along the axial direction on the inner peripheral surface of the moving clutch member 72. When the circumferential spline portion 76 is slidably engaged, the moving clutch member 72 is attached to the case 60 so as to be integrally rotatable and movable in the axial direction.
　この移動クラッチ部材７２には、シート幅方向内側へ開口した環状溝が形成されており、当該環状溝内には、噛合いクラッチ機構４８の構成部材である金属製の圧縮コイルスプリング７８が収容されている。この圧縮コイルスプリング７８は、移動クラッチ部材７２と同軸的に配置されており、軸線方向一端部が第２クラッチ部材５４に当接すると共に、軸線方向他端部が上記環状溝の底面に当接している。これにより、移動クラッチ部材７２は、シート幅方向外側へ向けて付勢されており、通常はシート幅方向外側の端面がケース６０の底壁６２に当接した状態に保持されている。 The moving clutch member 72 is formed with an annular groove that opens inward in the seat width direction, and a metal compression coil spring 78 that is a component of the mesh clutch mechanism 48 is accommodated in the annular groove. ing. The compression coil spring 78 is disposed coaxially with the moving clutch member 72, and has one axial end abutting against the second clutch member 54 and the other axial end abutting against the bottom surface of the annular groove. Yes. Accordingly, the moving clutch member 72 is urged toward the outer side in the sheet width direction, and is normally held in a state where the end surface on the outer side in the sheet width direction is in contact with the bottom wall 62 of the case 60.
　上述の移動クラッチ部材７２は、図７～図９に示されるように、軸線方向一端側（シート幅方向内側）が大径部７２Ａとされ、軸線方向他端側（シート幅方向外側）が小径部７２Ｂとされている。小径部７２Ｂのシート幅方向外側の端面には、シート幅方向外側へ向けて突出した複数（ここでは３つ）の棒状部８０が設けられている。これらの棒状部８０は、円柱状に形成されており、軸線方向がシート幅方向に沿う状態で移動クラッチ部材７２の周方向に等間隔に並んで配置されている。これらの棒状部８０は、前述したケース６０の底壁６２に設けられた複数の筒状部７０に挿入されており、先端側が筒状部７０よりもシート幅方向外側へ突出している。これらの棒状部８０は、後述する切替部材１３６に対応している。 As shown in FIGS. 7 to 9, the moving clutch member 72 has a large diameter portion 72A on one end side in the axial direction (inner side in the sheet width direction) and a small diameter on the other end side in the axial direction (outer side in the sheet width direction). Part 72B. A plurality (three in this case) of rod-shaped portions 80 projecting outward in the sheet width direction are provided on the end surface of the small diameter portion 72B on the outer side in the sheet width direction. These rod-shaped portions 80 are formed in a columnar shape, and are arranged at equal intervals in the circumferential direction of the moving clutch member 72 in a state where the axial direction is along the seat width direction. These rod-shaped portions 80 are inserted into the plurality of tubular portions 70 provided on the bottom wall 62 of the case 60 described above, and the leading end side protrudes outward in the sheet width direction from the tubular portion 70. These rod-shaped portions 80 correspond to a switching member 136 described later.
　また、移動クラッチ部材７２の大径部７２Ａにおけるシート幅方向内側の面には、移動クラッチ部材７２の全周にわたって他側噛合部８２（クラッチ歯）が形成されている。この他側噛合部８２は、移動クラッチ部材７２の周方向（回転方向）に等間隔に並んだ複数の歯８３によって構成されており、第２クラッチ部材５４の第２噛合部５８に対して噛合い可能とされている。第２噛合部５８と他側噛合部８２とが噛み合った状態では、第２クラッチ部材５４と移動クラッチ部材７２とが一体回転可能に連結される。但し、通常は圧縮コイルスプリング７８の付勢力によって移動クラッチ部材７２が第２クラッチ部材５４から離間する位置に保持されており、第２噛合部５８と他側噛合部８２との噛合いが解除されている。 Further, the other side meshing portion 82 (clutch teeth) is formed on the inner surface in the seat width direction of the large diameter portion 72A of the moving clutch member 72 over the entire circumference of the moving clutch member 72. The other-side meshing portion 82 includes a plurality of teeth 83 arranged at equal intervals in the circumferential direction (rotation direction) of the moving clutch member 72, and meshes with the second meshing portion 58 of the second clutch member 54. Is possible. In a state where the second meshing portion 58 and the other meshing portion 82 are meshed with each other, the second clutch member 54 and the moving clutch member 72 are coupled so as to be integrally rotatable. However, the moving clutch member 72 is normally held at a position away from the second clutch member 54 by the urging force of the compression coil spring 78, and the meshing between the second meshing portion 58 and the other meshing portion 82 is released. ing.
　また、移動クラッチ部材７２の大径部７２Ａにおけるシート幅方向外側の面には、移動クラッチ部材７２の全周にわたって一側噛合部８４（クラッチ歯）が形成されている。この一側噛合部８４は、移動クラッチ部材７２の周方向（回転方向）に等間隔に並んだ複数の歯８５によって構成されており、第１クラッチ部材８６（外側クラッチ部材）に対応している。 Further, a one-side meshing portion 84 (clutch teeth) is formed over the entire circumference of the moving clutch member 72 on the outer surface in the seat width direction of the large diameter portion 72A of the moving clutch member 72. The one-side meshing portion 84 is configured by a plurality of teeth 85 arranged at equal intervals in the circumferential direction (rotation direction) of the moving clutch member 72, and corresponds to the first clutch member 86 (outer clutch member). .
　第１クラッチ部材８６は、噛合いクラッチ機構４８の構成部材であり、リング状に形成された本体部８８を備えている。この本体部８８は、移動クラッチ部材７２と共にケース６０の内側に収容されている。本体部８８の外周部には、径方向外側に突出した一対の凸部が設けられており、これらの凸部がケース６０の周壁６３の内周面に形成された凹溝に嵌入している。これにより、本体部８８は、ケース６０に対して軸線方向移動不能で且つ所定範囲相対回転可能に連結されている。この本体部８８の内側には、移動クラッチ部材７２の小径部７２Ｂが回転自在に挿入されており、第１クラッチ部材８６は、移動クラッチ部材７２に対して相対回転自在とされている。この本体部８８の軸線方向一端面（シート幅方向内側の端面）には、本体部８８の全周にわたって第１噛合部９０（クラッチ歯）が形成されている。この第１噛合部９０は、本体部８８の周方向（回転方向）に等間隔に並んだ複数の歯９１によって構成されており、移動クラッチ部材７２の一側噛合部８４に対して噛合い可能とされている。この第１噛合部９０は、移動クラッチ部材７２が圧縮コイルスプリング７８の付勢力によってシート幅方向外側へ付勢されていることにより、通常は一側噛合部８４と噛み合っている。このように、この一側噛合部８４とクラッチ歯車９０とが噛み合った状態では、移動クラッチ部材７２と第１クラッチ部材８６とが一体回転可能に連結されるようになっている。 The first clutch member 86 is a constituent member of the meshing clutch mechanism 48 and includes a main body 88 formed in a ring shape. The main body 88 is housed inside the case 60 together with the moving clutch member 72. A pair of convex portions projecting radially outward are provided on the outer peripheral portion of the main body portion 88, and these convex portions are fitted into concave grooves formed on the inner peripheral surface of the peripheral wall 63 of the case 60. . Thus, the main body 88 is connected to the case 60 so as not to move in the axial direction and to be rotatable relative to a predetermined range. A small diameter portion 72 </ b> B of the moving clutch member 72 is rotatably inserted inside the main body portion 88, and the first clutch member 86 is rotatable relative to the moving clutch member 72. A first meshing portion 90 (clutch teeth) is formed on one end surface in the axial direction (end surface on the inner side in the sheet width direction) of the main body portion 88 over the entire circumference of the main body portion 88. The first meshing portion 90 is composed of a plurality of teeth 91 arranged at equal intervals in the circumferential direction (rotation direction) of the main body portion 88 and can mesh with the one-side meshing portion 84 of the moving clutch member 72. It is said that. The first meshing portion 90 normally meshes with the one-side meshing portion 84 when the moving clutch member 72 is urged outward in the seat width direction by the urging force of the compression coil spring 78. Thus, in a state where the one-side meshing portion 84 and the clutch gear 90 mesh with each other, the moving clutch member 72 and the first clutch member 86 are coupled so as to be integrally rotatable.
　但し、移動クラッチ部材７２が圧縮コイルスプリング７８の付勢力に抗してシート幅方向内側へ変位すると、第１クラッチ部材８６の第１噛合部９０と移動クラッチ部材７２の一側噛合部８４との噛合いが解除されると共に、移動クラッチ部材７２の他側噛合部８２と第２クラッチ部材５４の第２噛合部５８とが噛み合うようになっている。この状態では、前述したように、移動クラッチ部材７２と第２クラッチ部材５４とが一体回転可能に連結される。 However, when the moving clutch member 72 is displaced inward in the seat width direction against the urging force of the compression coil spring 78, the first meshing portion 90 of the first clutch member 86 and the one-side meshing portion 84 of the moving clutch member 72 are in contact with each other. While the meshing is released, the other meshing portion 82 of the moving clutch member 72 and the second meshing portion 58 of the second clutch member 54 are meshed with each other. In this state, as described above, the moving clutch member 72 and the second clutch member 54 are coupled so as to be integrally rotatable.
　さらに、上述の第１クラッチ部材８６には、図３及び図４に示されるように、本体部８８の半径方向外側へ突出した連結部９２が設けられている。この連結部９２は、ケース６０の周壁６３の一部に形成された切欠を介してケース６０の外側へ突出しており、シート後方斜め下方へ向けて延びている。この連結部９２は、リンク部材９４及びワイヤ９６に対応している。 Furthermore, as shown in FIGS. 3 and 4, the first clutch member 86 is provided with a connecting portion 92 that protrudes outward in the radial direction of the main body portion 88. The connecting portion 92 protrudes to the outside of the case 60 through a notch formed in a part of the peripheral wall 63 of the case 60 and extends obliquely downward to the rear of the seat. The connecting portion 92 corresponds to the link member 94 and the wire 96.
　ワイヤ９６は、一端部が前述したスライド機構３８のロック解除レバー４６に係止されており、他端部が上記連結部９２に係止されている。このため、連結部９２がシート後方側へ変位する方向（図３及び図４の矢印Ｃ方向）に第１クラッチ部材８６が回転すると、第１クラッチ部材８６の回転力がワイヤ９６を介してロック解除レバー４６に伝達され、ロック解除レバー４６がロック解除方向へ回転される。これにより、スライド機構３８のロックが解除される。 The wire 96 has one end engaged with the lock release lever 46 of the slide mechanism 38 and the other end engaged with the connecting portion 92. For this reason, when the first clutch member 86 rotates in the direction in which the connecting portion 92 is displaced rearward of the seat (the direction of arrow C in FIGS. 3 and 4), the rotational force of the first clutch member 86 is locked via the wire 96. The signal is transmitted to the release lever 46, and the lock release lever 46 is rotated in the lock release direction. Thereby, the lock | rock of the slide mechanism 38 is cancelled | released.
　一方、リンク部材９４は、板金材料によって長尺状に形成されている。このリンク部材９４の長手方向一端部は、図１及び図２に示されるように、前述したリクライニング機構２０のロック解除レバー２２の先端部に対して、シート幅方向に沿った連結軸９５を介して回転自在に連結されている。リンク部材９４の長手方向他端側には、シート幅方向外側へ開口したビード部９８が形成されている。このビード部９８は、リンク部材９４の長手方向に沿って延在している。このビード部９８は、連結部９２に設けられた凸部１００（図４参照）に対応している。 On the other hand, the link member 94 is formed in an elongated shape from a sheet metal material. As shown in FIGS. 1 and 2, one end of the link member 94 in the longitudinal direction is connected to the tip of the lock release lever 22 of the reclining mechanism 20 via a connecting shaft 95 along the seat width direction. And are rotatably connected. On the other end side in the longitudinal direction of the link member 94, a bead portion 98 that opens to the outside in the sheet width direction is formed. The bead portion 98 extends along the longitudinal direction of the link member 94. The bead portion 98 corresponds to the convex portion 100 (see FIG. 4) provided in the connecting portion 92.
　凸部１００は、連結部９２の先端部（下端部）からシート幅方向内側へ向けて突出しており、ビード部９８の内側に挿入されている。また、連結部９２の基端側からは、Ｌ字状の腕部１０２が延びており、当該腕部１０２がリンク部材９４のシート幅方向内側面に当接している。これにより、連結部９２がリンク部材９４に対してビード部９８に沿った範囲内で相対移動可能に連結されている。また、このリンク部材９４の長手方向他端部には、シート幅方向外側へ延びる当接片１０４が設けられており、当該当接片１０４が連結部９２に対してシート前方側から対向している。 The convex part 100 protrudes inward in the sheet width direction from the front end part (lower end part) of the connecting part 92 and is inserted inside the bead part 98. Further, an L-shaped arm portion 102 extends from the base end side of the connecting portion 92, and the arm portion 102 is in contact with the inner surface of the link member 94 in the sheet width direction. Thereby, the connection part 92 is connected with the link member 94 so that relative movement within the range along the bead part 98 is possible. Further, a contact piece 104 extending outward in the seat width direction is provided at the other longitudinal end of the link member 94, and the contact piece 104 faces the connecting portion 92 from the front side of the seat. Yes.
　このため、連結部９２がシート前方側へ変位する方向（図３及び図４の矢印Ｂ方向）へ第１クラッチ部材８６が回転すると、連結部９２が当接片１０４と当接することにより、リンク部材９４がシート前方側へ引っ張られる。これにより、第１クラッチ部材８６の回転力がリンク部材９４を介してロック解除レバー２２に伝達され、ロック解除レバー２２がロック解除方向へ回転される。これにより、リクライニング機構２０のロックが解除される。なおこの場合、連結部９２とロック解除レバー４６との間でワイヤ９６が撓むことにより、第１クラッチ部材８６の回転力がロック解除レバー４６には伝達されないようになっている。 Therefore, when the first clutch member 86 rotates in the direction in which the connecting portion 92 is displaced forward of the seat (the direction of arrow B in FIGS. 3 and 4), the connecting portion 92 contacts the contact piece 104, thereby The member 94 is pulled to the front side of the seat. Thereby, the rotational force of the 1st clutch member 86 is transmitted to the lock release lever 22 via the link member 94, and the lock release lever 22 rotates in a lock release direction. As a result, the reclining mechanism 20 is unlocked. In this case, the wire 96 is bent between the connecting portion 92 and the lock release lever 46 so that the rotational force of the first clutch member 86 is not transmitted to the lock release lever 46.
　一方、連結部９２がシート後方側へ変位する方向（図３及び図４の矢印Ｃ方向）へ第１クラッチ部材８６が回転した際には、前述したように、第１クラッチ部材８６の回転力がワイヤ９６を介してスライド機構３８のロック解除レバー２２に伝達される。この場合、凸部１００がビード部９８の後端側（上端側）へ移動することにより、連結部９２がリンク部材９４に対してシート後方側へ相対移動する。これにより、第１クラッチ部材８６の回転力がリンク部材９４を介してリクライニング機構２０のロック解除レバー２２に伝達されないようになっている。 On the other hand, when the first clutch member 86 rotates in the direction in which the connecting portion 92 is displaced rearward (the direction of arrow C in FIGS. 3 and 4), as described above, the rotational force of the first clutch member 86 is increased. Is transmitted to the lock release lever 22 of the slide mechanism 38 via the wire 96. In this case, when the convex portion 100 moves to the rear end side (upper end side) of the bead portion 98, the connecting portion 92 moves relative to the link member 94 to the rear side of the seat. Thereby, the rotational force of the first clutch member 86 is not transmitted to the lock release lever 22 of the reclining mechanism 20 via the link member 94.
　上述した噛合いクラッチ機構４８は、カバー１０６によって覆われている。カバー１０６は、樹脂材料によってシート幅方向内側が開口した略有底円筒状に形成されており、ポンプ式リフタ装置３４と同軸的に配置されている。このカバー１０６は、開口側の縁部に設けられたフランジ部１０８が図示しない複数のボルト及びナットによってシートクッションフレーム１６における車両幅方向外側の側面に締結固定されている。このカバー１０６の周壁１１０は、軸線方向中央部よりも底壁１１４側が円筒状に形成される一方、軸線方向中央部よりも開口側がシート幅方向内側へ向かうに従い拡径するように形成されている。また、カバー１０６の周壁１１０とフランジ部１０８との間には、複数の補強用リブ１１２が掛け渡されている。また、このカバー１０６の底壁１１４の中央部には、円形の貫通孔が同軸的に形成されており、当該貫通孔を介してケース６０の底壁６２がカバー１０６のシート幅方向外側へ露出している。カバー１０６の底壁１１４におけるシート幅方向外側の面には、前後一対の規制突起１１６が設けられている。これらの規制突起１１６は、底壁１１４の貫通孔を介して互いに反対側に配置されており、シート幅方向外側へ向けて突出している。これらの規制突起１１６は、後述する切替部材１３６に対応している。 The mesh clutch mechanism 48 described above is covered with a cover 106. The cover 106 is formed in a substantially bottomed cylindrical shape that is opened in the sheet width direction by a resin material, and is arranged coaxially with the pump type lifter device 34. In the cover 106, a flange portion 108 provided at the edge on the opening side is fastened and fixed to a side surface of the seat cushion frame 16 on the outer side in the vehicle width direction by a plurality of bolts and nuts (not shown). The peripheral wall 110 of the cover 106 is formed such that the bottom wall 114 side is formed in a cylindrical shape with respect to the central portion in the axial direction, and the opening side is formed to increase in diameter toward the inner side in the sheet width direction from the central portion in the axial direction. . A plurality of reinforcing ribs 112 are spanned between the peripheral wall 110 of the cover 106 and the flange portion 108. A circular through hole is coaxially formed at the center of the bottom wall 114 of the cover 106, and the bottom wall 62 of the case 60 is exposed to the outside in the sheet width direction of the cover 106 through the through hole. is doing. A pair of front and rear restricting protrusions 116 is provided on the outer surface of the bottom wall 114 of the cover 106 in the seat width direction. These restricting protrusions 116 are arranged on the opposite sides through the through holes of the bottom wall 114, and protrude toward the outside in the sheet width direction. These restricting protrusions 116 correspond to a switching member 136 described later.
　カバー１０６のシート幅方向外側には、操作部材としての操作レバー１１８が配置されている。この操作レバー１１８は、シート調整装置１４を構成しており、レバー本体１２０と、蓋部１２２と備えている。レバー本体１２０は、樹脂材料によって長尺状に形成されており、シート幅方向外方側が開口した軸線方向寸法が短い略有底円筒状の基部１２４と、基部１２４の外周部からシート前方側へ延出されたアーム部１２６とによって構成されている。アーム部１２６は、シート幅方向外方側が開口した断面略Ｕ字状に形成されている。一方、蓋部１２２は、樹脂材料によって長尺な板状に形成されてレバー本体１２０の開口側（シート幅方向外側）に装着されており、レバー本体１２０の開口部を閉塞している。 An operation lever 118 as an operation member is disposed outside the cover 106 in the sheet width direction. The operation lever 118 constitutes the sheet adjustment device 14 and includes a lever main body 120 and a lid portion 122. The lever body 120 is formed in a long shape by a resin material, and has a substantially bottomed cylindrical base portion 124 having an axial dimension that is open on the outer side in the seat width direction, and an outer peripheral portion of the base portion 124 toward the seat front side. The arm portion 126 extends. The arm portion 126 is formed in a substantially U-shaped cross section that is open on the outer side in the sheet width direction. On the other hand, the lid 122 is formed in a long plate shape with a resin material and is mounted on the opening side (outer side in the sheet width direction) of the lever main body 120 to close the opening of the lever main body 120.
　この操作レバー１１８は、基部１２４の底壁１２８を貫通した複数（ここでは３つ）の図示しないネジが、噛合いクラッチ機構４８のケース６０の底壁６２に埋め込まれた図示しないナットに螺合することにより、ケース６０に締結固定されている。また、ケース６０の底壁６２に設けられた複数の凸部が基部１２４の底壁１２８に形成された凹部に嵌合している。このため、操作レバー１１８は、ケース６０と一体で回転するようになっている。なお、この操作レバー１１８の回転軸線Ａ（図３及び図４参照）は、本実施形態では入力軸３６、プレート５０、第２クラッチ部材５４、圧縮コイルスプリング７８、移動クラッチ部材７２、第１クラッチ部材８６及びケース６０の軸線と一致している。 In this operation lever 118, a plurality (three here) screws (not shown) penetrating the bottom wall 128 of the base portion 124 are screwed into nuts (not shown) embedded in the bottom wall 62 of the case 60 of the mesh clutch mechanism 48. By doing so, the case 60 is fastened and fixed. In addition, a plurality of convex portions provided on the bottom wall 62 of the case 60 are fitted in concave portions formed on the bottom wall 128 of the base portion 124. For this reason, the operation lever 118 rotates together with the case 60. In this embodiment, the rotation axis A of the operation lever 118 (see FIGS. 3 and 4) is the input shaft 36, the plate 50, the second clutch member 54, the compression coil spring 78, the moving clutch member 72, and the first clutch. It coincides with the axis of the member 86 and the case 60.
　また、基部１２４の底壁１２８には、前述したケース６０の複数の筒状部７０を挿通させるための貫通孔が形成されており、各筒状部７０を貫通した複数の棒状部８０の先端側が操作レバー１１８内（基部１２４内）に突出している。さらに、基部１２４の底壁１２８には、前後一対の円弧孔１３０が形成されている。これらの円弧孔１３０は、操作レバー１１８の回転中心を中心とする円弧状に形成されている。これらの円弧孔１３０には、前述したカバー１０６の一対の規制突起１１６が挿通されており、各規制突起１１６の先端側が操作レバー１１８内（基部１２４内）に突出している。 Further, the bottom wall 128 of the base portion 124 is formed with through holes for inserting the plurality of cylindrical portions 70 of the case 60 described above, and the tips of the plurality of rod-shaped portions 80 penetrating the respective cylindrical portions 70. The side projects into the operation lever 118 (in the base 124). Further, a pair of front and rear arc holes 130 are formed in the bottom wall 128 of the base portion 124. These arc holes 130 are formed in an arc shape centered on the rotation center of the operation lever 118. The pair of restricting protrusions 116 of the cover 106 described above are inserted through these arc holes 130, and the distal end side of each restricting protrusion 116 protrudes into the operation lever 118 (inside the base portion 124).
　この操作レバー１１８と前述したカバー１０６との間には、付勢部材としての捩りコイルスプリング１３２が配置されている。この捩りコイルスプリング１３２は、図５及び図６に示されるように、基部１２４の底壁１２８に形成された環状溝内に収容されており、捩り方向一端部に形成された一端側係止部が基部１２４に係止されると共に、捩り方向他端部に形成された他端側係止部がカバー１０６の底壁１１４に設けられた係止部１３４に係止されている。これにより、操作レバー１１８は、通常は捩りコイルスプリング１３２の付勢力によって図１及び図２に示される中立位置に保持されており、アーム部１２６が中立位置よりも上側へ持ち上げられた際、及び中立位置よりも下側へ押し下げられた際には、捩りコイルスプリング１３２が弾性変形するようになっている。このため、アーム部１２６に持ち上げ力又は押し下げ力が作用しなくなると、操作レバー１１８が捩りコイルスプリング１３２の付勢力によって中立位置へと復帰する。 A torsion coil spring 132 as an urging member is disposed between the operation lever 118 and the cover 106 described above. As shown in FIGS. 5 and 6, the torsion coil spring 132 is accommodated in an annular groove formed in the bottom wall 128 of the base portion 124, and one end side locking portion formed at one end portion in the torsion direction. The other end side locking portion formed at the other end in the twisting direction is locked to the locking portion 134 provided on the bottom wall 114 of the cover 106. Thereby, the operation lever 118 is normally held at the neutral position shown in FIGS. 1 and 2 by the biasing force of the torsion coil spring 132, and when the arm portion 126 is lifted above the neutral position, and The torsion coil spring 132 is elastically deformed when pushed down from the neutral position. For this reason, when the lifting force or the pushing-down force no longer acts on the arm portion 126, the operation lever 118 returns to the neutral position by the urging force of the torsion coil spring 132.
　また、操作レバー１１８の内側には、切替部材１３６が収容されている。切替部材１３６は、樹脂材料によって長尺状に形成されており、操作レバー１１８の長手方向に沿って配置されている。この切替部材１３６は、レバー本体１２０及びカバー１０６に設けられた図示しない複数の支持部と係合しており、操作レバー１１８に対して長手方向にスライド可能に支持されている。この切替部材１３６は、長手方向一端側が棒状のロッド部１３８とされ、長手方向他端側が板状のプレート部１４０とされており、ロッド部１３８とプレート部１４０との間には、長尺矩形枠状のスプリング収容部１４２が設けられている。さらに、ロッド部１３８の先端部（シート前方側の端部：スプリング収容部１４２とは反対側の端部）には、円柱状の操作ボタン部１４６が設けられている。この操作ボタン部１４６は、アーム部１２６の先端部（シート前方側の端部）に形成された円形の開口に挿通されてアーム部１２６よりもシート前方側へ突出している。 Further, a switching member 136 is accommodated inside the operation lever 118. The switching member 136 is formed in a long shape with a resin material, and is disposed along the longitudinal direction of the operation lever 118. The switching member 136 is engaged with a plurality of support portions (not shown) provided on the lever main body 120 and the cover 106, and is supported so as to be slidable in the longitudinal direction with respect to the operation lever 118. The switching member 136 has a rod-shaped rod portion 138 at one end in the longitudinal direction and a plate-like plate portion 140 at the other end in the longitudinal direction. A long rectangular shape is provided between the rod portion 138 and the plate portion 140. A frame-shaped spring accommodating portion 142 is provided. Furthermore, a columnar operation button portion 146 is provided at the tip end portion of the rod portion 138 (the end portion on the front side of the seat: the end portion on the side opposite to the spring accommodating portion 142). The operation button portion 146 is inserted through a circular opening formed at the tip end portion (the end portion on the front side of the seat) of the arm portion 126 and protrudes from the arm portion 126 toward the front side of the seat.
　また、ロッド部１３８は、アーム部１２６に沿って延在しており、アーム部１２６の基端部付近にスプリング収容部１４２が配置されている。このスプリング収容部１４２内には、圧縮コイルスプリング１４８が設けられている。圧縮コイルスプリング１４８は、軸線方向が操作レバー１１８の長手方向に沿う状態で配置されている。この圧縮コイルスプリング１４８の軸線方向一端部は、スプリング収容部１４２内におけるロッド部１３８側の端部に設けられた円柱状の位置決め部１４９が内側に嵌合することにより、スプリング収容部１４２に係止されている。また、圧縮コイルスプリング１４８の軸線方向他端部は、アーム部１２６の底壁から延出されてスプリング収容部１４２内に挿入された突片１５１に押し当てられている。これにより、切替部材１３６は、操作レバー１１８の前端側へ向けて付勢されている。このため、切替部材１３６は、通常は図１、図２、図１１及び図１２に示される非操作位置（第１位置）に保持されており、操作ボタン部１４６が操作レバー１１８側へ押し込まれることにより、図１３に示される操作位置（第２位置）へと移動される構成になっている。なお、操作ボタン部１４６に作用する押し込み力が開放されると、切替部材１３６は圧縮コイルスプリング１４８の付勢力によって非操作位置へと復帰する。 Further, the rod portion 138 extends along the arm portion 126, and the spring accommodating portion 142 is disposed near the base end portion of the arm portion 126. A compression coil spring 148 is provided in the spring accommodating portion 142. The compression coil spring 148 is arranged in a state where the axial direction is along the longitudinal direction of the operation lever 118. One end of the compression coil spring 148 in the axial direction is engaged with the spring accommodating portion 142 by fitting a cylindrical positioning portion 149 provided at the end of the rod accommodating portion 138 in the spring accommodating portion 142 to the inside. It has been stopped. The other end in the axial direction of the compression coil spring 148 is pressed against a projecting piece 151 that extends from the bottom wall of the arm portion 126 and is inserted into the spring accommodating portion 142. Thereby, the switching member 136 is urged toward the front end side of the operation lever 118. Therefore, the switching member 136 is normally held at the non-operation position (first position) shown in FIGS. 1, 2, 11, and 12, and the operation button portion 146 is pushed into the operation lever 118 side. Thus, the operation position (second position) shown in FIG. 13 is moved. When the pushing force acting on the operation button unit 146 is released, the switching member 136 is returned to the non-operation position by the urging force of the compression coil spring 148.
　一方、切替部材１３６のプレート部１４０は、板厚方向がシート幅方向に沿う状態で基部１２４内に収容されている。図５及び図６に示されるように、プレート部１４０のシート幅方向内側の面には、複数の傾斜突起１５０が設けられている。これらの傾斜突起１５０は、前述した移動クラッチ部材７２の複数の棒状部８０における先端部と対向する位置に配置されている。これらの傾斜突起１５０は、複数の棒状部８０側（シート幅方向内側）の端部が平坦な平坦面１５０Ａとされると共に、シート後方側の側面が傾斜面１５０Ｂとされている。傾斜面１５０Ｂは、平坦面１５０Ａに連続しており、シート後方側へ向かうに従いシート幅方向外側へ向かうように傾斜している。 On the other hand, the plate portion 140 of the switching member 136 is housed in the base portion 124 in a state where the plate thickness direction is along the sheet width direction. As shown in FIGS. 5 and 6, a plurality of inclined protrusions 150 are provided on the inner surface of the plate portion 140 in the sheet width direction. These inclined projections 150 are arranged at positions facing the tip portions of the plurality of rod-like portions 80 of the moving clutch member 72 described above. The inclined protrusions 150 have flat end surfaces 150A at the ends of the plurality of rod-shaped portions 80 (inner side in the sheet width direction), and inclined side surfaces 150B. The inclined surface 150B is continuous with the flat surface 150A, and is inclined so as to go outward in the seat width direction toward the rear side of the seat.
　図５に示されるように、切替部材１３６が非操作位置に位置する状態では、上記複数の傾斜突起１５０が複数の棒状部８０に対してシート前方側にずれた位置に配置される。この状態では、移動クラッチ部材７２が圧縮コイルスプリング７８の付勢力によって第２クラッチ部材５４から離間する位置に保持されており、移動クラッチ部材７２の一側噛合部８４と第１クラッチ部材８６の第１噛合部９０とが噛み合っている。 As shown in FIG. 5, in a state where the switching member 136 is located at the non-operation position, the plurality of inclined protrusions 150 are arranged at positions shifted to the front side of the seat with respect to the plurality of rod-shaped portions 80. In this state, the moving clutch member 72 is held at a position away from the second clutch member 54 by the urging force of the compression coil spring 78, and the one-side meshing portion 84 of the moving clutch member 72 and the first clutch member 86 are in the first position. One meshing portion 90 is meshed.
　一方、図６に示されるように、切替部材１３６が操作位置へとスライドされると、複数の棒状部８０の先端が複数の傾斜突起１５０の傾斜面１５０Ｂによってシート幅方向内側へ押されて平坦面１５０Ａに乗り上げることにより、移動クラッチ部材７２が圧縮コイルスプリング７８の付勢力に抗してシート幅方向内側へ移動される。これにより、移動クラッチ部材７２の一側噛合部８４と第１クラッチ部材８６の第１噛合部９０との噛合いが解除される一方、移動クラッチ部材７２の他側噛合部８２と第２クラッチ部材５４の第２噛合部５８とが噛み合うようになっている。 On the other hand, as shown in FIG. 6, when the switching member 136 is slid to the operating position, the tips of the plurality of rod-shaped portions 80 are pushed inward in the sheet width direction by the inclined surfaces 150 </ b> B of the plurality of inclined protrusions 150. By riding on the surface 150 </ b> A, the moving clutch member 72 is moved inward in the seat width direction against the urging force of the compression coil spring 78. As a result, the meshing between the one meshing portion 84 of the moving clutch member 72 and the first meshing portion 90 of the first clutch member 86 is released, while the other meshing portion 82 of the moving clutch member 72 and the second clutch member. 54 meshes with the second meshing portion 58.
　また、上述のプレート部１４０の前端部及び後端部には、それぞれ上下一対の規制片１５２が設けられている。これらの規制片１５２は、シート幅方向内側へ突出しており、前述した前後一対の規制突起１１６に対応している。つまり、切替部材１３６が非操作位置と操作位置との間で移動される際には、規制突起１１６の上側及び下側を上下一対の規制片１５２が通過する。このため、切替部材１３６が非操作位置と操作位置との間に位置する状態では、上下一対の規制片１５２が規制突起１１６と係合する（当る）ことにより、中立位置からの操作レバー８６の回転が規制される構成になっている。また、操作レバー１１８が中立位置の上側又は下側へ操作された状態（操作途中の状態も含む）では、上下一対の規制片１５２のうちの一方が規制突起１１６と当たることにより、非操作位置から操作位置への切替部材１３６の移動、又は操作位置から非操作位置への切替部材１３６の移動が規制されるようになっている。 Further, a pair of upper and lower restricting pieces 152 are provided at the front end portion and the rear end portion of the plate portion 140 described above. These restricting pieces 152 protrude inward in the sheet width direction and correspond to the pair of front and rear restricting protrusions 116 described above. That is, when the switching member 136 is moved between the non-operating position and the operating position, the pair of upper and lower restricting pieces 152 pass above and below the restricting protrusion 116. For this reason, in a state where the switching member 136 is positioned between the non-operation position and the operation position, the pair of upper and lower restriction pieces 152 engages (impacts) with the restriction protrusions 116, so that the operation lever 86 from the neutral position is moved. Rotation is restricted. In a state where the operation lever 118 is operated to the upper side or the lower side of the neutral position (including a state in the middle of operation), one of the pair of upper and lower restricting pieces 152 abuts against the restricting protrusion 116, thereby The movement of the switching member 136 from the operation position to the operation position or the movement of the switching member 136 from the operation position to the non-operation position is restricted.
　＜実施形態の要部＞
　次に、本実施形態の要部について説明する。前述したように、本実施形態では、切替部材１３６が非操作位置と操作位置との間で移動されることに伴って、噛合いクラッチ機構４８の移動クラッチ部材７２がシート幅方向（操作レバー１１８の回転軸線Ａ方向）に移動される。切替部材１３６は、通常は非操作位置に位置しており、この状態では、図７に示されるように、移動クラッチ部材７２の一側噛合部８４が第１クラッチ部材８６の第１噛合部９０と噛合っている。なお、この図７には、移動クラッチ部材７２が、ケース６０及び操作レバー１１８（図７では図示省略）と共に中立位置に位置する状態が図示されている。この図７に示される状態から、切替部材１３６が操作位置へと移動されると、移動クラッチ部材７２がシート幅方向内側（第２クラッチ部材５４側）へ移動され、移動クラッチ部材７２の他側噛合部８２が第２クラッチ部材５４の第２噛合部５８と噛合う。 <Main part of the embodiment>
Next, the main part of this embodiment will be described. As described above, in the present embodiment, as the switching member 136 is moved between the non-operation position and the operation position, the moving clutch member 72 of the meshing clutch mechanism 48 is moved in the sheet width direction (operation lever 118).

Specifically, the plurality of teeth 61 are formed in a rectangular shape on the proximal end side and in a triangular shape on the distal end side when viewed from the rotational radius direction (direction orthogonal to the rotational axis) of the second clutch member 54. Further, the plurality of teeth 83 and the plurality of teeth 85 are formed in a rectangular shape on the base end side and in a triangular shape on the tip end side when viewed from the rotational radius direction of the moving clutch member 72. Further, the plurality of teeth 91 are formed in a rectangular shape on the base end side as viewed from the rotational radius direction of the first clutch member 86 and in a triangular shape on the tip end side. The teeth 61, 83, 85, 91 have sharp tips, and ridge lines extending in the rotational radius direction of the clutch members 58, 72, 86 are formed at the tips of the teeth 61, 83, 85, 91. ing.
　また、本実施形態では、移動クラッチ部材８６に設けられた他側噛合部８２の複数の歯８３と、一側噛合部８４の複数の歯８５とが、移動クラッチ部材８６の周方向（回転方向）において互い違いに配置されている。図７に示されるように、第１クラッチ部材８６と係合した移動クラッチ部材７２が中立位置に位置する状態（図７図示状態）では、移動クラッチ部材７２における複数の歯８３が、第２クラッチ部材５４における複数の歯６１の間の谷の部分と対向するように、操作レバー１１８が捩りコイルスプリング１３２によって付勢されている。 In the present embodiment, the plurality of teeth 83 of the other-side meshing portion 82 provided on the moving clutch member 86 and the plurality of teeth 85 of the one-side meshing portion 84 are arranged in the circumferential direction (rotational direction) of the moving clutch member 86. ) Are alternately arranged. As shown in FIG. 7, when the moving clutch member 72 engaged with the first clutch member 86 is in the neutral position (shown in FIG. 7), the plurality of teeth 83 in the moving clutch member 72 are the second clutch. The operation lever 118 is biased by the torsion coil spring 132 so as to face the valley portion between the plurality of teeth 61 in the member 54.
　さらに、本実施形態では、図８及び図９に示されるように、移動クラッチ部材７２の一側噛合部８４が備える複数の歯８５は、一つの歯８５Ａの歯幅Ｗ１が他の歯８５Ｂの歯幅Ｗ２よりも大きく設定されている。また、図８及び図１０に示されるように、第１クラッチ部材８６の第１噛合部９０が備える複数の歯９１は、隣り合う一対の歯９１Ａの歯幅Ｗ３が、他の歯９１Ｂの歯幅Ｗ４よりも小さく設定されている。これら一対の歯９１Ａの間の間隔Ｗ５は、上述した歯８５Ａの歯幅Ｗ１よりも僅かに広く設定されており、歯８５Ａは一対の歯９１Ａの間にのみ挿入可能とされている。これにより、本実施形態では、移動クラッチ部材７２と第１クラッチ部材８６とが特定の角度でしか係合しないように構成されている。この角度は、第１クラッチ部材８６の連結部９２に対してリンク部材９４及びワイヤ９６を設定通りに連結できる角度とされている。なお、上述した歯８５Ａは、他の歯８５Ｂよりも歯幅が広く強度が高いため、他の歯８５Ｂよりも移動クラッチ部材７２の回転半径方向に沿った長さ寸法が短く設定されている。 Furthermore, in this embodiment, as FIG.8 and FIG.9 shows, as for the several tooth | gear 85 with which the one side meshing part 84 of the moving clutch member 72 is equipped, the tooth | gear width W1 of one tooth | gear 85A is the other tooth | gear 85B.

The tooth 85A described above has a wider tooth width and higher strength than the other teeth 85B, and therefore the length dimension along the rotational radius direction of the moving clutch member 72 is set shorter than that of the other teeth 85B.
　＜実施形態の作用及び効果＞
　次に、本実施形態の作用及び効果について説明する。
　上記構成の車両用シート１０では、操作レバー１１８がシートクッションフレーム１６に回転可能に取り付けられている。この操作レバー１１８は、シート本体１２に着座した乗員がアーム部１２６を把持して上下に操作することができる。また、この操作レバー１１８には、アーム部１２６の先端から突出した操作ボタン部１４６を備える切替部材１３６が取り付けられており、アーム部１２６を把持した乗員が親指等で操作ボタン部１４６を押圧操作することにより、切替部材１３６が非操作位置から操作位置へと移動される。 <Operation and Effect of Embodiment>
Next, the operation and effect of this embodiment will be described.
In the vehicle seat 10 configured as described above, the operation lever 118 is rotatably attached to the seat cushion frame 16. The operation lever 118 can be operated up and down by an occupant seated on the seat body 12 by gripping the arm portion 126. Further, a switching member 136 having an operation button part 146 protruding from the tip of the arm part 126 is attached to the operation lever 118, and an occupant holding the arm part 126 presses the operation button part 146 with a thumb or the like. As a result, the switching member 136 is moved from the non-operation position to the operation position.
　ここで、切替部材１３６が非操作位置に位置する状態（非操作状態）では、移動クラッチ部材７２の一側噛合部８４と第１クラッチ部材８６の第１噛合部９０とが噛み合うことにより、移動クラッチ部材７２と第１クラッチ部材８６とが一体回転可能に連結されている。この非操作状態において、操作レバー１１８のアーム部１２６が、図１１に二点鎖線で示されるように中立位置の上側（一側）へ操作されると、その操作力がケース６０に伝達され、ケース６０、移動クラッチ部材７２及び第１クラッチ部材８６が図３及び図４の矢印Ｂ方向へ回転される。この回転力は、リンク部材９４を介してリクライニング機構２０のロック解除レバー２２に伝達され、ロック解除レバー２２がロック解除方向に回転される。これにより、リクライニング機構２０のロックが解除され、シートバックのリクライニング角度を調整可能な状態になる。 Here, in a state where the switching member 136 is located at the non-operating position (non-operating state), the one-side meshing portion 84 of the moving clutch member 72 and the first meshing portion 90 of the first clutch member 86 mesh with each other to move. The clutch member 72 and the first clutch member 86 are coupled so as to be rotatable together. In this non-operating state, when the arm portion 126 of the operating lever 118 is operated to the upper side (one side) of the neutral position as shown by a two-dot chain line in FIG. 11, the operating force is transmitted to the case 60, The case 60, the moving clutch member 72, and the first clutch member 86 are rotated in the direction of arrow B in FIGS. This rotational force is transmitted to the lock release lever 22 of the reclining mechanism 20 via the link member 94, and the lock release lever 22 is rotated in the lock release direction. As a result, the reclining mechanism 20 is unlocked and the reclining angle of the seat back can be adjusted.
　また、上記非操作状態において、操作レバー１１８のアーム部１２６が、図１２に二点鎖線で示されるように中立位置の下側（他側）へ操作されると、その操作力がケース６０に伝達され、ケース６０、移動クラッチ部材７２及び第１クラッチ部材８６が図３及び図４の矢印Ｃ方向へ回転される。この回転力は、ワイヤ９６を介してスライド機構３８のロック解除レバー４６に伝達され、ロック解除レバー４６がロック解除方向に回転される。これにより、スライド機構３８のロックが解除され、車両用シート１０の前後位置を調整可能な状態になる。 Further, in the non-operating state, when the arm portion 126 of the operating lever 118 is operated to the lower side (the other side) of the neutral position as shown by a two-dot chain line in FIG. As a result, the case 60, the moving clutch member 72, and the first clutch member 86 are rotated in the direction of arrow C in FIGS. This rotational force is transmitted to the unlock lever 46 of the slide mechanism 38 via the wire 96, and the unlock lever 46 is rotated in the unlock direction. Thereby, the lock | rock of the slide mechanism 38 is cancelled | released and it will be in the state which can adjust the front-back position of the vehicle seat 10. FIG.
　一方、乗員が操作ボタン部１４６を押圧操作することにより、切替部材１３６が操作位置へと移動された状態（操作状態）では、移動クラッチ部材７２の複数の棒状部８０が切替部材１３６の複数の傾斜突起１５０に押されることにより、移動クラッチ部材７２がシート幅方向内側へ移動する。これにより、移動クラッチ部材７２の一側噛合部８４と第１クラッチ部材８６の第１噛合部９０との噛合いが解除されると共に、移動クラッチ部材７２の他側噛合部８２と第２クラッチ部材５４の第２噛合部５８とが噛み合う。これにより、移動クラッチ部材７２と第２クラッチ部材５４とが一体回転可能に連結される。この操作状態において、操作レバー１１８のアーム部１２６が、図１３に二点鎖線で示されるように中立位置の上側（一側）へ操作されると、その操作力がケース６０、移動クラッチ部材７２、第２クラッチ部材５４及びプレート５０を介してポンプ式リフタ装置３４（リフタ機構２６）の入力軸３６に伝達される。これにより、入力軸３６が図３及び図４の矢印Ｂ方向へ回転されると共に、当該入力軸３６の回転力がピニオン３３及びリフタギヤ３５介して後側リンク３２に伝達され、シートクッションフレーム１６がロアフレーム２８に対して上方へ変位する（シート高さが高く調整される）。なお、図１３ではシートクッションフレーム１６がロアフレーム２８に対して変位した状態については図示を省略している。 On the other hand, in a state where the switching member 136 is moved to the operation position (operation state) by the occupant pressing the operation button unit 146, the plurality of rod-shaped portions 80 of the moving clutch member 72 are connected to the plurality of switching members 136. By being pushed by the inclined protrusion 150, the moving clutch member 72 moves inward in the sheet width direction. As a result, the meshing between the one meshing portion 84 of the moving clutch member 72 and the first meshing portion 90 of the first clutch member 86 is released, and the other meshing portion 82 of the moving clutch member 72 and the second clutch member. 54 second meshing portions 58 mesh with each other. Thereby, the movement clutch member 72 and the 2nd clutch member 54 are connected so that integral rotation is possible. In this operating state, when the arm portion 126 of the operating lever 118 is operated to the upper side (one side) of the neutral position as shown by a two-dot chain line in FIG. 13, the operating force is applied to the case 60 and the moving clutch member 72. Then, it is transmitted to the input shaft 36 of the pump type lifter device 34 (lifter mechanism 26) via the second clutch member 54 and the plate 50. As a result, the input shaft 36 is rotated in the direction of arrow B in FIGS. 3 and 4, and the rotational force of the input shaft 36 is transmitted to the rear link 32 via the pinion 33 and the lifter gear 35. It is displaced upward with respect to the lower frame 28 (the seat height is adjusted high). In FIG. 13, the state where the seat cushion frame 16 is displaced with respect to the lower frame 28 is not shown.
　また、上記操作状態において、操作レバー８６のアーム部１２６が、図１３に一点鎖線で示されるように中立位置の下側（他側）へ操作されると、その操作力がケース６０、移動クラッチ部材７２、第２クラッチ部材５４及びプレート５０を介してポンプ式リフタ装置３４の入力軸３６に伝達される。これにより、入力軸３６が図３及び図４の矢印Ｃ方向へ回転されると共に、当該入力軸３６の回転力がピニオン３３及びリフタギヤ３５を介して後側リンク３２に伝達され、シートクッションフレーム１６がロアフレーム２８に対して下方へ変位する（シート高さが低く調整される）。 Further, in the above operation state, when the arm portion 126 of the operation lever 86 is operated to the lower side (the other side) of the neutral position as shown by a one-dot chain line in FIG. It is transmitted to the input shaft 36 of the pump lifter device 34 via the member 72, the second clutch member 54 and the plate 50. As a result, the input shaft 36 is rotated in the direction of arrow C in FIGS. 3 and 4, and the rotational force of the input shaft 36 is transmitted to the rear link 32 via the pinion 33 and the lifter gear 35. Is displaced downward with respect to the lower frame 28 (the seat height is adjusted low).
　このように、本車両用シート１０では、上下２方向へ操作可能な１つの操作レバー１１８によって、リクライニング機構２０、スライド機構３８、及びリフタ機構２６を調整し又は調整可能な状態にすることができる。しかも、操作レバー１１８のアーム部１２６の操作方向が上側及び下側のみであり、単純であるため、操作性の向上及びスペースの有効利用を図ることができる。特に、車両用シートと車体側部（サイドドア等）との間のスペースを広く確保することが困難な小型車などにも適用可能な点で好適である。 As described above, in the vehicle seat 10, the reclining mechanism 20, the slide mechanism 38, and the lifter mechanism 26 can be adjusted or brought into an adjustable state by one operation lever 118 that can be operated in two directions. . In addition, since the operation direction of the arm portion 126 of the operation lever 118 is only the upper side and the lower side and is simple, the operability can be improved and the space can be effectively used. In particular, it is preferable in that it can be applied to a small vehicle or the like in which it is difficult to secure a wide space between the vehicle seat and the vehicle body side portion (side door or the like).
　しかも、本実施形態では、操作レバー１１８と一体回転可能に設けられた移動クラッチ部材７２が操作レバー１１８の回転軸線Ａ方向に移動されて第２クラッチ部材５４又は第１クラッチ部材８６と係合する。このため、例えば移動クラッチ部材７２が操作レバー１１８の回転半径方向（回転軸線Ａと直交する方向）に移動されて他のクラッチ部材と係合する構成と比較して、移動クラッチ部材７２と第１クラッチ部材８６との係合面、及び移動クラッチ部材７２と第２クラッチ部材５４との係合面を広く設定することができる。つまり、本実施形態のように、各クラッチ部材５４、７２、８６を円筒状（リング状）ないし円板状に形成することにより、各クラッチ部材５４、７２、８６における他のクラッチ部材との係合面を広く設定することができる。これにより、操作レバー１１８の操作力（トルク）を上記広い係合面に分散することができるので、上記各クラッチ部材５４、７２、８６の伝達許容トルクを向上させることができる。このため、本実施形態のように、各クラッチ部材５４、７２、８６が樹脂材料によって形成されている場合でも、各クラッチ部材５４、７２、８６の伝達許容トルクを所望の値に設定することが可能になるので、上記各クラッチ部材５４、７２、８６の軽量化を図ることができる。 In addition, in this embodiment, the moving clutch member 72 provided so as to rotate integrally with the operation lever 118 is moved in the direction of the rotation axis A of the operation lever 118 and engages with the second clutch member 54 or the first clutch member 86. . Therefore, for example, the moving clutch member 72 and the first moving clutch member 72 are moved in the rotational radius direction of the operation lever 118 (direction orthogonal to the rotational axis A) and engaged with the other clutch members. The engaging surface with the clutch member 86 and the engaging surface between the moving clutch member 72 and the second clutch member 54 can be set widely. That is, as in the present embodiment, each clutch member 54, 72, 86 is formed in a cylindrical shape (ring shape) or a disk shape, so that the clutch members 54, 72, 86 are engaged with other clutch members. A wide face can be set. As a result, the operating force (torque) of the operating lever 118 can be distributed over the wide engagement surface, so that the transmission allowable torque of the clutch members 54, 72, 86 can be improved. For this reason, even if each clutch member 54, 72, 86 is formed of a resin material as in this embodiment, the transmission allowable torque of each clutch member 54, 72, 86 can be set to a desired value. Since it becomes possible, weight reduction of each said clutch member 54,72,86 can be achieved.
　なお、背景技術の欄で説明した特許文献１に記載の発明では、操作レバーに設けられた切替ピンを、リクライニングプレートの係合溝又はリフタプレートの係合溝に係合させて操作力を伝達する構成になっている。このため、上記各係合溝と切替ピンとの係合面の面積が小さく、操作力が分散されないため、切替ピン、リクライニングプレート、及びリフタプレートを樹脂部品化することが困難である。この点は、背景技術の欄で説明した特許文献２に記載の発明においても同様に、兼用操作レバーの操作力を伝達するロックレバーやロック部材等が操作力を分散する構成になっていないため、これらの部材を樹脂部品化することが困難であると考えられる。 In the invention described in Patent Document 1 described in the background art section, the operating force is transmitted by engaging the switching pin provided on the operating lever with the engaging groove of the reclining plate or the engaging groove of the lifter plate. It is configured to do. For this reason, since the area of the engaging surface between each of the engaging grooves and the switching pin is small and the operating force is not dispersed, it is difficult to make the switching pin, the reclining plate, and the lifter plate into resin parts. Similarly, in the invention described in Patent Document 2 described in the background art section, similarly, the lock lever and the lock member that transmit the operation force of the dual operation lever are not configured to distribute the operation force. Therefore, it is considered difficult to convert these members into resin parts.
　また、本実施形態では、噛合いクラッチ機構４８を構成するケース６０や噛合いクラッチ機構４８を覆うカバー１０６が樹脂材料によって形成されており、殆どの部材が樹脂化されている。これにより、シート調整装置１４の軽量化を図ることができるので、結果として車両用シート１０の全体構成を軽量化することが可能になる。 In this embodiment, the case 60 constituting the meshing clutch mechanism 48 and the cover 106 covering the meshing clutch mechanism 48 are formed of a resin material, and most of the members are made of resin. As a result, the weight of the seat adjustment device 14 can be reduced, and as a result, the overall configuration of the vehicle seat 10 can be reduced.
　さらに、本実施形態では、第２クラッチ部材５４の第２噛合部５８、移動クラッチ部材７２の他側噛合部８２、一側噛合部８４、及び第１クラッチ部材８６の第１噛合部９０は、各クラッチ部材５４、７２、８６の回転方向に並んだ複数の歯６１、８３、８５、９１によって構成されている。このため、他側噛合部８２と第２噛合部５８との噛合い状態において両者の間で伝達される操作レバー１１８の操作力、及び一側噛合部８４と第１噛合部９０との噛合い状態において両者の間で伝達される操作レバー１１８の操作力を、複数の歯６１、８３、８５、９１に分散することができるので、１歯当りの伝達トルクを低減することができる。このため、各クラッチ部材５４、７２、８６が樹脂材料によって形成された構成であっても、操作レバー１１８の操作力を各クラッチ部材５４、７２、８６を介して良好に伝達することができる。 Furthermore, in the present embodiment, the second meshing portion 58 of the second clutch member 54, the other meshing portion 82 of the moving clutch member 72, the one meshing portion 84, and the first meshing portion 90 of the first clutch member 86 are: A plurality of teeth 61, 83, 85, 91 are arranged in the rotational direction of the clutch members 54, 72, 86. Therefore, the operating force of the operating lever 118 transmitted between the other side meshing portion 82 and the second meshing portion 58 in the meshed state, and the meshing between the one side meshing portion 84 and the first meshing portion 90. Since the operating force of the operating lever 118 transmitted between the two in the state can be distributed to the plurality of teeth 61, 83, 85, 91, the transmission torque per tooth can be reduced. For this reason, even if each clutch member 54,72,86 is the structure formed of the resin material, the operation force of the operation lever 118 can be transmitted favorably through each clutch member 54,72,86.
　また、本実施形態では、上記各歯６１、８３、８５、９１が、各クラッチ部材５４、７２、８６の回転半径方向から見て先端側が三角形状（先細状）に形成されている。このため、移動クラッチ部材７２の他側噛合部８２が第２クラッチ部材５４の第２噛合部５８と噛み合う際に、他側噛合部８２の複数の歯８３と第２噛合部５８の複数の歯６１とが移動クラッチ部材７２及び第２クラッチ部材５４の回転方向にずれている場合には、これらの歯６１、８３における先細状の先端側が互いに摺接する。これにより、上記ずれが解消するように移動クラッチ部材７２及び第２クラッチ部材５４のうちの少なくとも一方を回転させることができる。同様に、移動クラッチ部材７２の一側噛合部８４が第１クラッチ部材８６の第１噛合部９０と噛み合う際に、一側噛合部８４の複数の歯８５と第１噛合部９０の複数の歯９１とが移動クラッチ部材７２及び第１クラッチ部材８６の回転方向にずれている場合には、これらの歯における先細状の先端側が互いに摺接する。これにより、上記ずれが解消するように移動クラッチ部材７２及び第１クラッチ部材８６のうちの少なくとも一方を回転させることができる。したがって、切替部材１３６の操作に伴う移動クラッチ部材７２の移動、すなわちクラッチ切替動作を円滑なものにすることができる。 Further, in the present embodiment, the teeth 61, 83, 85, 91 are formed in a triangular shape (tapered shape) on the tip side when viewed from the rotational radius direction of the clutch members 54, 72, 86. Therefore, when the other meshing portion 82 of the moving clutch member 72 meshes with the second meshing portion 58 of the second clutch member 54, the plurality of teeth 83 of the other meshing portion 82 and the plurality of teeth of the second meshing portion 58 are engaged. 61 are displaced in the rotational direction of the moving clutch member 72 and the second clutch member 54, the tapered tip ends of these teeth 61 and 83 are in sliding contact with each other. Thereby, at least one of the moving clutch member 72 and the second clutch member 54 can be rotated so as to eliminate the above-described deviation. Similarly, when the one-side meshing portion 84 of the moving clutch member 72 meshes with the first meshing portion 90 of the first clutch member 86, the plurality of teeth 85 of the one-side meshing portion 84 and the plurality of teeth of the first meshing portion 90. 91 is displaced in the rotational direction of the moving clutch member 72 and the first clutch member 86, the tapered tip ends of these teeth are in sliding contact with each other. Thereby, at least one of the moving clutch member 72 and the first clutch member 86 can be rotated so as to eliminate the above-described deviation. Therefore, the movement of the moving clutch member 72 accompanying the operation of the switching member 136, that is, the clutch switching operation can be made smooth.
　また、本実施形態では、移動クラッチ部材７２の複数の歯８３は、一つの歯８３Ａの歯幅Ｗ１が他の歯８３Ｂの歯幅Ｗ２よりも大きく設定されており、第１クラッチ部材８６の複数の歯９１は、隣り合う一対の歯９１Ａの歯幅Ｗ３が上記幅広な歯８３Ａに対応して他の歯９１Ｂの歯幅Ｗ４よりも大きく設定されている。これにより、移動クラッチ部材７２と第１クラッチ部材８６とが特定の角度でしか係合しないように構成されており、当該特定の角度においては、リンク部材９４及びワイヤ９６を連結部９２に対して設定通りに連結できるようになっている。これにより、リンク部材９４を介して第１クラッチ部材８６と連結されたリクライニング機構２０、及びワイヤ９６を介して第１クラッチ部材８６と連結されたスライド機構３８が誤作動することを防止することができる。また、移動クラッチ部材７２に対して第１クラッチ部材８６を組み付ける際に誤組付を防止することができる。 Further, in the present embodiment, the plurality of teeth 83 of the moving clutch member 72 is configured such that the tooth width W1 of one tooth 83A is set larger than the tooth width W2 of the other tooth 83B. In the tooth 91, the tooth width W3 of a pair of adjacent teeth 91A is set larger than the tooth width W4 of the other tooth 91B corresponding to the wide tooth 83A. Accordingly, the moving clutch member 72 and the first clutch member 86 are configured to engage only at a specific angle. At the specific angle, the link member 94 and the wire 96 are connected to the connecting portion 92. It can be linked as set. This prevents the reclining mechanism 20 connected to the first clutch member 86 via the link member 94 and the slide mechanism 38 connected to the first clutch member 86 via the wire 96 from malfunctioning. it can. Further, erroneous assembly can be prevented when the first clutch member 86 is assembled to the moving clutch member 72.
　さらに、本実施形態では、操作レバー１１８を回転範囲の一側と他側との中間に設定された中立位置へと付勢する専用の捩りコイルスプリング１３２を有している。これにより、一側又は他側へ操作された操作レバー１１８が中立位置に復帰する際には操作力を要しないようにすることができるので、操作レバー１１８の操作を容易なものにすることができる。しかも、操作レバー１１８のアーム部１２６が中立位置の上側及び下側の何れの側へ操作される場合においても、同一の捩りコイルスプリング１３２が弾性変形される構成になっている。これにより、操作レバー１１８の操作フィーリングを良好なものにすることができる。 Furthermore, in the present embodiment, a dedicated torsion coil spring 132 that urges the operation lever 118 to a neutral position set between the one side and the other side of the rotation range is provided. Accordingly, when the operation lever 118 operated to one side or the other side returns to the neutral position, no operation force can be required, so that the operation lever 118 can be easily operated. it can. Moreover, the same torsion coil spring 132 is elastically deformed when the arm portion 126 of the operation lever 118 is operated to either the upper side or the lower side of the neutral position. Thereby, the operation feeling of the operation lever 118 can be made favorable.
　また、本実施形態では、操作レバー１１８に取り付けられた切替部材１３６が非操作位置と操作位置との間に位置する状態では、カバー１０６に設けられた規制突起１１６が切替部材１３６の規制片１５２と係合することにより、中立位置からの操作レバー１１８の回転が規制される。このため、切替部材１３６が非操作位置と操作位置との間に位置する状態、すなわち操作レバー１１８が第２クラッチ部材５４及び第１クラッチ部材８６の両方と連結される可能性がある状態で、操作レバー１１８が回転されることを防止できる。これにより、誤作動が生じること、すなわち２つの被調整機構が同時に調整等されることを回避できる。 In this embodiment, when the switching member 136 attached to the operation lever 118 is positioned between the non-operation position and the operation position, the restriction protrusion 116 provided on the cover 106 is the restriction piece 152 of the switching member 136. , The rotation of the operation lever 118 from the neutral position is restricted. For this reason, in a state where the switching member 136 is located between the non-operation position and the operation position, that is, in a state where the operation lever 118 may be coupled to both the second clutch member 54 and the first clutch member 86, It is possible to prevent the operation lever 118 from rotating. As a result, it is possible to avoid malfunctions, that is, the two adjusted mechanisms being adjusted simultaneously.
　しかも、操作レバー１１８が中立位置の上側又は下側へ操作された状態（操作途中の状態も含む）では、規制片１５２が規制突起１１６と当たることにより、非操作位置から操作位置への切替部材１３６の移動、又は操作位置から非操作位置への切替部材１３６の移動が規制される。このため、操作レバー１１８の操作中に切替部材１３６が移動されることにより、操作レバー１１８と第１クラッチ部材８６との連結状態、又は操作レバー１１８と第２クラッチ部材５４との連結状態が不用意に解除されることを防止できる。したがって、これによっても誤操作を防止することができる。 In addition, when the operation lever 118 is operated to the upper side or the lower side of the neutral position (including a state in the middle of operation), the switching member from the non-operation position to the operation position is caused by the restriction piece 152 coming into contact with the restriction protrusion 116. The movement of 136 or the movement of the switching member 136 from the operation position to the non-operation position is restricted. Therefore, when the switching member 136 is moved during the operation of the operation lever 118, the connection state between the operation lever 118 and the first clutch member 86 or the connection state between the operation lever 118 and the second clutch member 54 is not good. It can be prevented that it is released. Therefore, it is possible to prevent erroneous operation also by this.
　さらに、本実施形態では、操作レバー１１８がシート幅方向に沿った軸線回りに回転可能とされており、操作レバー１１８の操作方向が上側及び下側とされている。このため、車両が前、後、左又は右から衝突された場合でも、操作レバー１１８が自重等によって不用意に回転されることを防止又は効果的に抑制することができる。つまり、背景技術の欄で説明した兼用操作レバーのように、車両幅方向にも操作される構成の場合には、兼用操作レバーが車両の側面衝突時等に不用意に操作（回転）される可能性がある。この場合、例えば、リクライニング機構やスライド機構のロックが不用意に解除されてしまう虞があるが、本実施形態では、上述の如き構成によりこれを回避することができる。 Furthermore, in the present embodiment, the operation lever 118 is rotatable around an axis along the sheet width direction, and the operation direction of the operation lever 118 is the upper side and the lower side. For this reason, even when the vehicle collides from the front, rear, left, or right, it is possible to prevent or effectively suppress the operation lever 118 from being inadvertently rotated by its own weight or the like. In other words, in the case of a configuration that is also operated in the vehicle width direction, such as the dual operation lever described in the background section, the dual operation lever is inadvertently operated (rotated) in the event of a side collision of the vehicle. there is a possibility. In this case, for example, the reclining mechanism or the slide mechanism may be unlocked carelessly, but in the present embodiment, this can be avoided by the configuration as described above.
　また、本車両用シート１０では、リフタ機構２６を構成するポンプ式リフタ装置３４の入力軸３６と操作レバー１１８とが同軸的に配置されているため、操作レバー１１８の操作力を入力軸３６に伝達するための構成を簡素で小型なものにすることができる。したがって、これによってもシート調整装置１４の小型化を図ることができ、スペースの有効利用を図ることができる。 Further, in the vehicle seat 10, the input shaft 36 and the operation lever 118 of the pump type lifter device 34 constituting the lifter mechanism 26 are arranged coaxially, so that the operation force of the operation lever 118 is applied to the input shaft 36. The structure for transmission can be made simple and small. Therefore, the sheet adjusting device 14 can be reduced in size and the space can be effectively used.
　＜実施形態の補足説明＞

However, the present invention is not limited to this, and the input shaft 36 of the pump lifter device 34 and the operation lever 118 are operated. The lever 118 may be spaced apart and connected via a gear or the like.
　また、上記実施形態では、第１クラッチ部材８６（第１クラッチ部材）の回転力が、リンク部材９４を介してリクライニング機構２０（第１の被調整機構）に伝達されると共に、ワイヤ９６を介してスライド機構３８（第２の被調整機構）に伝達される構成にしたが、本発明はこれに限らず、リンク部材やワイヤ以外の部材を用いてもよい。 In the above embodiment, the rotational force of the first clutch member 86 (first clutch member) is transmitted to the reclining mechanism 20 (first adjusted mechanism) via the link member 94 and via the wire 96. However, the present invention is not limited to this, and a member other than a link member or a wire may be used.
　また、上記実施形態では、移動クラッチ部材８６に設けられた他側噛合部８２の複数の歯８３と、一側噛合部８４の複数の歯８５とが、移動クラッチ部材８６の周方向（回転方向）において互い違いに配置された構成にしたが、本発明はこれに限らず、歯８３と歯８５とが移動クラッチ部材８６の回転軸線方向に並んで配置された構成にしてもよい。 In the above embodiment, the plurality of teeth 83 of the other-side meshing portion 82 provided on the moving clutch member 86 and the plurality of teeth 85 of the one-side meshing portion 84 are arranged in the circumferential direction (rotation direction) of the moving clutch member 86. However, the present invention is not limited to this, and the tooth 83 and the tooth 85 may be arranged side by side in the direction of the rotation axis of the moving clutch member 86.
　また、上記実施形態では、一側噛合部８４の複数の歯８５のうちの一つの歯８５Ａの歯幅Ｗ１が他の歯８５Ｂの歯幅Ｗ２よりも大きく設定されると共に、第１噛合部９０の複数の歯９１のうち隣り合う一対の歯９１Ａの歯幅Ｗ３が他の歯９１Ｂの歯幅Ｗ４よりも小さく設定された構成にしたが、本発明はこれに限らず、一側噛合部及び第１噛合部は、第１クラッチ部材が移動クラッチ部材に対して特定の角度に位置する状態でしか噛合わないように形状が設定されたものであればよい。例えば、一側噛合部の複数の歯及び第１噛合部の複数の歯において、一部の歯の歯厚が他の歯の歯厚とは異なって設定された構成にしてもよい。つまり、前記一部の歯の形状と前記他の歯の形状が異なることにより、移動クラッチ部材と第１クラッチ部材との係合角度が特定の角度に限定されるものであればよい。また、本発明には、一側噛合部の複数の歯及び第１噛合部の複数の歯が全て同じ形状に設定された構成も含まれる。 In the above embodiment, the tooth width W1 of one tooth 85A among the plurality of teeth 85 of the one side meshing portion 84 is set larger than the tooth width W2 of the other teeth 85B, and the first meshing portion 90 is set. The tooth width W3 of the pair of adjacent teeth 91A among the plurality of teeth 91 is set to be smaller than the tooth width W4 of the other teeth 91B. However, the present invention is not limited to this, and the one-side meshing portion and The first meshing portion only needs to have a shape set so that the first clutch member meshes only when the first clutch member is positioned at a specific angle with respect to the moving clutch member. For example, in the plurality of teeth of the one side meshing portion and the plurality of teeth of the first meshing portion, the tooth thickness of some teeth may be set differently from the tooth thickness of other teeth. That is, it is only necessary that the engagement angle between the moving clutch member and the first clutch member is limited to a specific angle because the shape of the part of teeth and the shape of the other teeth are different. The present invention also includes a configuration in which the plurality of teeth of the one-side meshing portion and the plurality of teeth of the first meshing portion are all set to the same shape.
　また、上記実施形態では、操作レバー１１８のアーム部１２６が中立位置の上側及び下側の何れの側へ操作される場合においても、同一の捩りコイルスプリング１３２が弾性変形される構成にしたが、本発明はこれに限らず、操作レバーが一側に操作される場合には、一の付勢部材が操作レバーを中立位置へと付勢し、操作レバーが他側へ操作される場合には、他の付勢部材が操作レバーを中立位置へと付勢する構成にしてもよい。また、付勢部材は、圧縮コイルスプリングに限らず、他の種類の付勢部材（例えば、ゴム等）を用いることもできる。 In the above embodiment, the same torsion coil spring 132 is elastically deformed when the arm portion 126 of the operation lever 118 is operated to either the upper side or the lower side of the neutral position. The present invention is not limited to this. When the operating lever is operated to one side, one biasing member biases the operating lever to the neutral position, and when the operating lever is operated to the other side. The other biasing member may bias the operation lever to the neutral position. Further, the urging member is not limited to the compression coil spring, and other types of urging members (for example, rubber or the like) can be used.
　また、上記実施形態では、操作ボタン部１４６の非操作状態で操作レバー１１８が操作されると、リクライニング機構２０及びスライド機構３８のロック機構が解除され、操作ボタン部１４６の操作状態で操作レバー１１８が操作されると、リフタ機構２６が調整される構成にしたが、本発明はこれに限らず、操作ボタン部１４６の非操作状態で操作レバー１１８が操作されると、リフタ機構２６が調整され、操作ボタン部１４６の操作状態で操作レバー１１８が操作されると、リクライニング機構２０及びスライド機構３８のロックが解除される構成にしてもよい。 In the above embodiment, when the operation lever 118 is operated while the operation button unit 146 is not operated, the locking mechanism of the reclining mechanism 20 and the slide mechanism 38 is released, and the operation lever 118 is operated while the operation button unit 146 is operated. However, the present invention is not limited to this, and the lifter mechanism 26 is adjusted when the operation lever 118 is operated when the operation button unit 146 is not operated. When the operation lever 118 is operated in the operation state of the operation button unit 146, the reclining mechanism 20 and the slide mechanism 38 may be unlocked.
　また、上記実施形態では、第１の被調整機構がリクライニング機構２０とされ、第２の被調整機構がスライド機構３８とされ、第３の被調整機構がリフタ機構２６とされた場合について説明したが、本発明はこれに限らず、被調整機構には、上記以外の機構（ランバーサポート機構、チルト機構、オットマン機構、サイサポート機構など）も含まれる。 In the above embodiment, the case where the first adjusted mechanism is the reclining mechanism 20, the second adjusted mechanism is the slide mechanism 38, and the third adjusted mechanism is the lifter mechanism 26 has been described. However, the present invention is not limited to this, and the mechanisms to be adjusted include mechanisms other than those described above (such as a lumbar support mechanism, a tilt mechanism, an ottoman mechanism, and a rhino support mechanism).
　また、上記実施形態では、第１クラッチ部材８６に２つの被調整機構（リクライニング機構２０及びスライド機構３８）が連結された構成にしたが、本発明はこれに限らず、第１クラッチ部材に１つの被調整機構が連結された構成にしてもよい。すなわち、例えば、上記実施形態において、ワイヤ９６及びロック解除レバー４６を省略すれば、第１クラッチ部材８６には、１つの被調整機構（リクライニング機構２０）が連結された構成になる。その場合、１つの操作レバー１１８によって、２つの被調整機構（リクライニング機構２０及びリフタ機構２６）を個別に調整し又は調整可能な状態にすることができる。 Moreover, in the said embodiment, although it was set as the structure by which two to-be-adjusted mechanisms (the reclining mechanism 20 and the slide mechanism 38) were connected with the 1st clutch member 86, this invention is not limited to this, 1st clutch member is 1 A configuration in which two adjusted mechanisms are connected may be employed. That is, for example, in the above-described embodiment, if the wire 96 and the lock release lever 46 are omitted, the first clutch member 86 is connected to one adjusted mechanism (the reclining mechanism 20). In that case, the two adjusted mechanisms (the reclining mechanism 20 and the lifter mechanism 26) can be individually adjusted or made adjustable by one operating lever 118.
　また、例えば、上記実施形態において、リフタ機構２６の代わりにオットマン機構（第３の被調整機構）及びサイサポート機構（第４の被調整機構）が設けられている場合には、オットマン機構に設けられたロック機構と第２クラッチ部材５４とを連結部材（ケーブル、リンク等）を介して連結すると共に、サイサポート機構に設けられた図示しないロック機構と第２クラッチ部材５４とを別の連結部材（ケーブル、リンク等）を介して連結する。この場合、例えば、乗員による操作ボタン部１４６の操作状態において、操作レバー１１８のアーム部１２６が中立位置の上側へ操作されると、その操作力がオットマン機構のロック機構に伝達され、操作レバー１１８のアーム部１２６が中立位置の下側へ操作されると、その操作力がサイサポート機構のロック機構に伝達される構成になる。これにより、１つの操作レバー１１８によって４つの被調整機構（リクライニング機構２０、スライド機構３８、オットマン機構及びサイサポート機構）を個別に調整し又は調整可能な状態にすることができる。 Further, for example, in the above-described embodiment, when the ottoman mechanism (third adjusted mechanism) and the rhino support mechanism (fourth adjusted mechanism) are provided instead of the lifter mechanism 26, the ottoman mechanism is provided. The lock mechanism and the second clutch member 54 are connected via a connecting member (cable, link, etc.), and the lock mechanism (not shown) provided in the rhino support mechanism and the second clutch member 54 are connected to another connecting member. Connect via cables (links, etc.). In this case, for example, when the arm 126 of the operation lever 118 is operated to the upper side of the neutral position in the operation state of the operation button 146 by the occupant, the operation force is transmitted to the lock mechanism of the ottoman mechanism. When the arm portion 126 is operated to the lower side of the neutral position, the operation force is transmitted to the lock mechanism of the rhino support mechanism. As a result, the four adjusted mechanisms (the reclining mechanism 20, the slide mechanism 38, the ottoman mechanism, and the thy support mechanism) can be individually adjusted or made adjustable by one operating lever 118.
　また、上記実施形態では、切替部材１３６が非操作位置（第１位置）と操作位置（第２位置）との間で移動される構成にしたが、本発明はこれに限らず、切替部材が第１位置から第２位置を経由して第３位置、第４位置などへと移動される構成にしてもよい。 In the above embodiment, the switching member 136 is moved between the non-operation position (first position) and the operation position (second position). However, the present invention is not limited to this, and the switching member It may be configured to move from the first position to the third position, the fourth position, etc. via the second position.
　また、上記実施形態では、操作レバー１１８がシート本体１２に対してシート幅方向に沿った軸線回りに回転可能に取り付けられた構成にしたが、本発明はこれに限らず、操作レバーはシート本体に対して回転可能に取り付けられたものであればよく、操作レバーの操作方向は適宜変更することができる。 In the above embodiment, the operation lever 118 is attached to the sheet main body 12 so as to be rotatable about an axis along the sheet width direction. However, the present invention is not limited thereto, and the operation lever is not limited to the sheet main body. The operation direction of the operation lever can be changed as appropriate.
　その他、本発明は、その要旨を逸脱しない範囲で種々変更して実施できる。また、本発明の権利範囲が上記実施形態に限定されないことはいうまでもない。 In addition, the present invention can be implemented with various modifications without departing from the scope of the invention. Needless to say, the scope of rights of the present invention is not limited to the above embodiment.
