　また、シートバックが上下に移動可能な乗物用シートにおいて、バックパネルに対してシートバックを上下に移動可能とする移動機構は、バックパネルに簡単に組み付けられることが望まれる。また、シートバックが上下に移動可能な乗物用シートにおいては、シートバックが良好に上下動できることが望まれる。 Also, in a vehicle seat in which the seat back can move up and down, it is desirable that the moving mechanism that allows the seat back to move up and down with respect to the back panel is easily assembled to the back panel. Further, in a vehicle seat in which the seat back can move up and down, it is desired that the seat back can move up and down well.
　そこで、本発明は、シートバックとバックパネルとの間にデッドスペースができることを抑制することができるとともに、シートバックの前側のスペースを確保することができる乗物用シートの取付構造を提供することを目的とする。
　また、本発明は、シートバックをバックパネルに取り付けるときの作業性を向上させることを目的とする。
　また、本発明は、シートバックを安定して支持することを目的とする。
　また、本発明は、移動機構の組み付け剛性を向上させることを目的とする。
　また、本発明は、バックパネルに対する上部フレームの角度を調整可能とすることを目的とする。
　また、本発明は、大型化を抑制しつつ、乗物用シートの内部にダクトを配設することを目的とする。
　また、本発明は、ダクトに荷重がかかることを抑制することを目的とする。
　また、本発明は、隣接部材がアームレスト収納部を有する構成において、シートバックが移動するときのアームレストと隣接部材の干渉を抑制することを目的とする。
　また、本発明は、バックパネルと移動機構を簡単に組み付けることを目的とする。
　また、本発明は、シートバックを良好に上下動させることを目的とする。
　また、本発明は、シートバックフレームの構成を簡略化することを目的とする。 Therefore, the present invention provides a vehicle seat mounting structure that can suppress the formation of a dead space between a seat back and a back panel and can secure a space on the front side of the seat back. Objective.

　図６に示す状態から、着座者の操作などによってアクチュエータＡＣ（図２参照）を駆動させ、シートクッションフレームＦ１（シートクッションＳ１０）を前に向けて移動させると、図８（ａ）に示すように、シートクッションフレームＦ１に引っ張られて、シートバックフレームＦ２の下部フレーム２０の下端部が前に移動する。これにより、下部フレーム２０が軸Ａ２を中心に前に回動しながら下方に移動することで、上部フレーム１０を下に引き下げ、上部フレーム１０が移動機構Ｍによってバックパネル６０に対して下に移動する。この結果、図８（ｂ）に示すように、シートバックＳ２０は、シートクッションＳ１０に対して後方に倒れた状態となる。 Next, the reclining operation of the vehicle seat S (left seat SL) will be described.
When the actuator AC (see FIG. 2) is driven by a seated person's operation from the state shown in FIG. 6 and the seat cushion frame F1 (seat cushion S10) is moved forward, as shown in FIG. 8 (a). The lower end of the lower frame 20 of the seat back frame F2 is moved forward by being pulled by the seat cushion frame F1. As a result, the lower frame 20 moves downward while rotating forward about the axis A2, thereby lowering the upper frame 10, and the upper frame 10 is moved downward with respect to the back panel 60 by the moving mechanism M. To do. As a result, as shown in FIG. 8B, the seat back S20 falls to the rear with respect to the seat cushion S10.
　一方、図８（ｂ）に示す状態から、アクチュエータＡＣを駆動させ、シートクッションフレームＦ１を後ろに向けて移動させると、図８（ａ）に示すように、シートクッションフレームＦ１に押されて、シートバックフレームＦ２の下部フレーム２０の下端部が後ろに移動する。これにより、下部フレーム２０が軸Ａ２を中心に後ろに回動しながら上方に移動することで、上部フレーム１０を上に押し上げ、上部フレーム１０が移動機構Ｍによってバックパネル６０に対して上に移動する。この結果、図６に示すように、シートバックＳ２０は、シートクッションＳ１０に対して起きた状態となる。 On the other hand, when the actuator AC is driven from the state shown in FIG. 8B and the seat cushion frame F1 is moved rearward, as shown in FIG. 8A, the seat cushion frame F1 is pushed. The lower end portion of the lower frame 20 of the seat back frame F2 moves backward. As a result, the lower frame 20 moves upward while pivoting about the axis A 2, thereby pushing up the upper frame 10, and the upper frame 10 is moved upward with respect to the back panel 60 by the moving mechanism M. To do. As a result, as shown in FIG. 6, the seat back S20 is in a state of being raised with respect to the seat cushion S10.
　以上説明した本実施形態によれば、図６に示したように、移動機構Ｍがバックパネル６０の凹部６３内に入り込んだ状態で配置されているので、シートバックＳ２０をバックパネル６０に寄せて、シートバックＳ２０とバックパネル６０とを近接させた状態で配置することができる。これにより、シートバックＳ２０のシート対向面６１とバックパネル６０との間にデッドスペースができることを抑制することができるとともに、シートバックＳ２０の前側のスペースを確保することができる。 According to the present embodiment described above, as shown in FIG. 6, the moving mechanism M is arranged in a state where it enters the recess 63 of the back panel 60, so that the seat back S <b> 20 is brought close to the back panel 60.

　ダクト８０は、電気自動車やハイブリッド自動車などにおいてバックパネル６０の後ろに配置されたバッテリ６６を冷却するため、冷却用の空気を、車室内からバッテリ６６が収容されたケース６７内に供給する管状の部材である。ダクト８０の一方の開口部８０Ａは、左サイド部Ｓ４に配設され、左サイド部Ｓ４の前側の空間、すなわち、車室内に連通している。また、ダクト８０の他方の開口部８０Ｂは、ケース６７内に配設され、バッテリ６６が配置されたケース６７内の空間に連通している。なお、左サイド部Ｓ４を覆う表皮材は、開口部８０Ａから車室内の空気を取り入れ可能なように、通気性を有している。本実施形態において、ダクト８０は、車体に対して動かないように固定されている。 The duct 80 has a tubular shape for supplying cooling air from the vehicle interior to the case 67 in which the battery 66 is accommodated in order to cool the battery 66 disposed behind the back panel 60 in an electric vehicle, a hybrid vehicle, or the like. It is a member. One opening 80A of the duct 80 is disposed in the left side portion S4 and communicates with the space on the front side of the left side portion S4, that is, the vehicle interior. The other opening 80B of the duct 80 is disposed in the case 67 and communicates with a space in the case 67 in which the battery 66 is disposed. The skin material covering the left side portion S4 has air permeability so that air in the vehicle compartment can be taken in from the opening 80A. In the present embodiment, the duct 80 is fixed so as not to move with respect to the vehicle body.
　ダクト８０は、上下方向から見たとき、メインフレームＦ２１の左端部の後ろの位置から、上部延出部１１０と下部延出部２１０の間を通って、左サイド部Ｓ４内に入るように、左右方向外側の斜め前方に向けて延びるように配置されている。これにより、ダクト８０は、左右方向における中央部が、上下方向から見て、上部延出部１１０および下部延出部２１０と重なるように配置されている。また、下部延出部２１０の第４部分２１４は、上下方向から見て、ダクト８０の左右方向における中央部よりも前側に配置されている。 When viewed from the vertical direction, the duct 80 passes from the position behind the left end of the main frame F21 between the upper extension portion 110 and the lower extension portion 210 and enters the left side portion S4. It arrange | positions so that it may extend toward the diagonally forward of the left-right direction outer side. Thereby, the duct 80 is arranged so that the central part in the left-right direction overlaps with the upper extension part 110 and the lower extension part 210 when viewed from the vertical direction. Further, the fourth portion 214 of the lower extension portion 210 is disposed on the front side of the central portion in the left-right direction of the duct 80 when viewed from the up-down direction.
　図１３に示すように、ダクト８０は、前後方向から見たとき、下部フレーム２０の左端部の後ろの位置から、上部延出部１１０と下部延出部２１０の間を通って、左サイド部Ｓ４内に入るように、左右方向外側の斜め上方に向けて延びるように配置されている。ダクト８０は、シートバックフレームＦ２が初期位置から下方位置に移動するのに伴う上部延出部１１０の移動範囲を避けて配置されている。具体的に、ダクト８０は、シートバックフレームＦ２が図１３に示す初期位置にあるとき、上部延出部１１０との間に、シートバックフレームＦ２の初期位置から下方位置への移動に伴う上部延出部１１０の下方への移動距離よりも大きな間隔Ｄ５をあけた状態で、上部延出部１１０の下に配置されている As shown in FIG. 13, when viewed from the front-rear direction, the duct 80 passes from the position behind the left end portion of the lower frame 20 between the upper extension portion 110 and the lower extension portion 210 to the left side portion. It arrange | positions so that it may extend toward diagonally upward of the left-right direction outer side so that it may enter in S4. The duct 80 is disposed so as to avoid the range of movement of the upper extension 110 as the seat back frame F2 moves from the initial position to the lower position. Specifically, when the seat back frame F2 is in the initial position shown in FIG. 13, the duct 80 is between the upper extension portion 110 and the upper extension along with the movement of the seat back frame F2 from the initial position to the lower position. It arrange | positions under the upper extension part 110 in the state which opened the space | interval D5 larger than the moving distance to the downward direction of the protrusion part 110.

It is arranged on the lower extension part 210 in the approached state.
　次に、車両用シートＳのリクライニング動作について説明する。
　図１６（ａ）に示す状態から、着座者の操作などによってアクチュエータＡＣ（図１０参照）を駆動させ、シートクッションフレームＦ１（シートクッションＳ１０）を前に向けて移動させると、シートクッションフレームＦ１に引っ張られて、シートバックフレームＦ２の下部フレーム２０の下端部が前に移動する。これにより、下部フレーム２０が軸Ａ２を中心に前に回動しながら下方に移動することで、上部フレーム１０を下に引き下げ、上部フレーム１０がパネル側部材４０にガイドされながらバックパネル６０に対して下にスライド移動する。この結果、図１６（ｂ）に示すように、シートバックＳ２０は、シートクッションＳ１０に対して後方に倒れた状態となる。 Next, the reclining operation of the vehicle seat S will be described.
When the actuator AC (see FIG. 10) is driven by a seated person's operation from the state shown in FIG. 16A and the seat cushion frame F1 (seat cushion S10) is moved forward, the seat cushion frame F1 is moved to the seat cushion frame F1. By being pulled, the lower end portion of the lower frame 20 of the seat back frame F2 moves forward. As a result, the lower frame 20 moves downward while rotating forward about the axis A 2, thereby pulling down the upper frame 10 and moving the upper frame 10 against the back panel 60 while being guided by the panel side member 40. Slide down. As a result, as shown in FIG. 16B, the seat back S20 falls to the rear with respect to the seat cushion S10.
　このとき、上部延出部１１０は、シートバックフレームＦ２が図１３に示す初期位置から図１７に示す下方位置に移動するのに伴って、上部フレーム１０が下にスライド移動することで、ダクト８０に近づくように下にスライド移動し、下部延出部２１０は、シートバックフレームＦ２が初期位置から下方位置に移動するのに伴って、下部フレーム２０が軸Ａ２を中心に前に回動しながら下方に移動することで、ダクト８０から遠ざかるように前斜め下に向けて移動する。本実施形態では、ダクト８０が、シートバックフレームＦ２の初期位置から下方位置への移動に伴う上部延出部１１０の移動範囲を避けて配置されているので、図１７に示すように、シートバックフレームＦ２が初期位置から下方位置に移動するときの、上部延出部１１０（シートバックフレームＦ２）とダクト８０との干渉を抑制することができる。 At this time, the upper extension part 110 slides the upper frame 10 downward as the seat back frame F2 moves from the initial position shown in FIG. 13 to the lower position shown in FIG. As the seat back frame F2 moves from the initial position to the lower position, the lower extension portion 210 is rotated forward about the axis A2 as the seat back frame F2 moves from the initial position to the lower position. By moving downward, it moves forward and obliquely downward so as to move away from the duct 80. In the present embodiment, the duct 80 is disposed so as to avoid the range of movement of the upper extension portion 110 that accompanies the movement of the seat back frame F2 from the initial position to the lower position, so as shown in FIG. Interference between the upper extension 110 (the seat back frame F2) and the duct 80 when the frame F2 moves from the initial position to the lower position can be suppressed.
　図１６（ｂ）に示す状態から、アクチュエータＡＣを駆動させ、シートクッションフレームＦ１を後ろに向けて移動させると、シートクッションフレームＦ１に押されて、シートバックフレームＦ２の下部フレーム２０の下端部が後ろに移動する。これにより、下部フレーム２０が軸Ａ２を中心に後ろに回動しながら上方に移動することで、上部フレーム１０を上に押し上げ、上部フレーム１０がパネル側部材４０にガイドされながらバックパネル６０に対して上にスライド移動する。この結果、図１６（ａ）に示すように、シートバックＳ２０は、シートクッションＳ１０に対して起きた状態となる。 When the actuator AC is driven and the seat cushion frame F1 is moved backward from the state shown in FIG. 16B, the lower end portion of the lower frame 20 of the seat back frame F2 is pushed by the seat cushion frame F1. Move back. As a result, the lower frame 20 moves upward while pivoting back about the axis A 2, thereby pushing up the upper frame 10 and moving the upper frame 10 against the back panel 60 while being guided by the panel side member 40. And slide up. As a result, as shown in FIG. 16A, the seat back S20 is raised with respect to the seat cushion S10.
　以上説明した本実施形態によれば、図１５に示したように、ダクト８０が、上下方向から見て、上部延出部１１０および下部延出部２１０と重なるように配置されているので、例えば、ダクトが延出部の後ろを通って、延出部の左右方向外側まで延び、その後、延出部の左右方向外側を通るように配置される構成と比較して、前後方向や左右方向における車両用シートＳの大型化を抑制することができる。これにより、車両用シートＳの大型化を抑制しつつ、車両用シートＳ内にダクト８０を配設することができる。その結果、小型自動車などにおいても、車両用シートＳ内にダクト８０を配設する構成を適用することが可能となる。また、ダクト８０が、上下方向から見て、上部延出部１１０および下部延出部２１０と重なるように配置されていることで、ダクト８０の形状、さらに言えば、配管構造をある程度自由に設計することが可能となる。 According to this embodiment described above, as shown in FIG. 15, the duct 80 is disposed so as to overlap with the upper extension portion 110 and the lower extension portion 210 when viewed from the vertical direction. The duct extends behind the extension part to the outside in the left-right direction of the extension part, and then in the front-rear direction and the left-right direction as compared with the configuration arranged to pass the outside in the left-right direction of the extension part. The enlargement of the vehicle seat S can be suppressed. Thereby, the duct 80 can be disposed in the vehicle seat S while suppressing an increase in size of the vehicle seat S. As a result, it is possible to apply a configuration in which the duct 80 is disposed in the vehicle seat S even in a small automobile or the like. Further, the duct 80 is arranged so as to overlap with the upper extension portion 110 and the lower extension portion 210 when viewed from the vertical direction, so that the shape of the duct 80, that is, the piping structure can be designed to some extent freely. It becomes possible to do.
　また、本実施形態では、荷重受け部材Ｍ３（図１４参照）や下部延出部２１０の第４部分２１４が、ダクト８０よりも前側に配置されているので、着座者からの荷重を、荷重受け部材Ｍ３やシートバックフレームＦ２を構成する下部延出部２１０で受けることができる。さらに、本実施形態では、ダクト８０が、上部延出部１１０と下部延出部２１０の間に配置されているので、上下方向からの荷重を、シートバックフレームＦ２を構成する上部延出部１１０や下部延出部２１０で受けることができる。これらにより、中空のダクト８０に荷重がかかることを抑制することができる。 Further, in the present embodiment, the load receiving member M3 (see FIG. 14) and the fourth portion 214 of the lower extension portion 210 are disposed in front of the duct 80, so that the load from the seated person can be received. It can be received by the lower extension part 210 constituting the member M3 and the seat back frame F2. Furthermore, in this embodiment, since the duct 80 is disposed between the upper extension portion 110 and the lower extension portion 210, the upper extension portion 110 constituting the seat back frame F2 is subjected to a load from the vertical direction. Or the lower extension 210. By these, it can suppress that a load is applied to the hollow duct 80.
　また、本実施形態では、図１３に示したように、シートバックフレームＦ２が初期位置にあるとき、ダクト８０と下部延出部２１０との間隔Ｄ６が、ダクト８０と上部延出部１１０との間隔Ｄ５よりも小さくなっているので、上下方向における上部延出部１１０と下部延出部２１０の間隔を小さくすることができる。これにより、上下方向におけるシートバックフレームＦ２（シートバックＳ２０）のコンパクト化が可能となる。 Further, in the present embodiment, as shown in FIG. 13, when the seat back frame F <b> 2 is in the initial position, the interval D <b> 6 between the duct 80 and the lower extension portion 210 is set between the duct 80 and the upper extension portion 110. Since it is smaller than the interval D5, the interval between the upper extension portion 110 and the lower extension portion 210 in the vertical direction can be reduced. As a result, the seat back frame F2 (seat back S20) in the vertical direction can be made compact.
　また、本実施形態では、上部延出部１１０および下部延出部２１０が、上下方向において、支持部材３３０を避けた位置に設けられているので、シートバックが中折れするための可動部分に延出部を設ける構成と比較して、延出部Ｆ２２を簡易な構成で設けることができる。これにより、シートバックフレームＦ２の構成を全体として簡略化することができる。 Further, in the present embodiment, since the upper extension portion 110 and the lower extension portion 210 are provided at positions away from the support member 330 in the vertical direction, the extension portion extends to a movable portion for folding the seat back. Compared with the configuration in which the protruding portion is provided, the extending portion F22 can be provided in a simple configuration. Thereby, the structure of the seat back frame F2 can be simplified as a whole.
　また、本実施形態では、被ガイド部３１が、支持部材３３０に接合されているので、上部フレーム１０と下部フレーム２０を回動可能に支持する剛性の高い支持部材３３０と、被ガイド部３１とを一体的な構成とすることができる。これにより、被ガイド部３１の組み付け剛性を向上させることができ、シートバックフレームＦ２の剛性を全体として向上させることができる。 In this embodiment, since the guided portion 31 is joined to the support member 330, the highly rigid support member 330 that rotatably supports the upper frame 10 and the lower frame 20, the guided portion 31, and the like. Can be integrated. Thereby, the assembly | attachment rigidity of the to-be-guided part 31 can be improved, and the rigidity of the seat back frame F2 can be improved as a whole.

　次に、車両用シートＳのリクライニング動作と、車両用シートＳがリクライニング動作するときのアームレストＳ２４の動きについて説明する。なお、ここでは、代表例として左シートＳ２およびアームレストＳ２４の動きについて説明するが、右シートＳ３およびアームレストＳ２５，Ｓ３４，Ｓ３５も同様の動きをする。 Next, the reclining operation of the vehicle seat S and the movement of the armrest S24 when the vehicle seat S performs the reclining operation will be described. Here, the movement of the left seat S2 and the armrest S24 will be described as a representative example, but the right seat S3 and the armrests S25, S34, and S35 also perform the same movement.
　図２４（ａ）に示す状態から、着座者の操作などによってアクチュエータＡＣ（図２０参照）を駆動させ、シートクッションフレームＦ１（シートクッションＳ２１）を前に向けて移動させると、シートクッションフレームＦ１に引っ張られて、シートバックフレームＦ２の下部フレーム２０の下端部が前に移動する。これにより、下部フレーム２０が軸Ａ２を中心に前に回動しながら下方に移動することで、上部フレーム１０を下に引き下げ、上部フレーム１０が移動機構Ｍによってバックパネル６０に対して下に移動する。この結果、図２４（ｂ）に示すように、シートバックＳ２２は、シートクッションＳ２１に対して後方に倒れた状態となる。このとき、アームレストＳ２４は、シートバックＳ２２が図２４（ａ）に示す初期位置から図２４（ｂ）に示す下方位置に移動するのに伴って、下部フレーム２０が軸Ａ２を中心に前に回動しながら下方に移動することで、図２２、図２５（ａ）および図２５（ｂ）と順に示すように、前斜め下方に向けて移動する。 When the actuator AC (see FIG. 20) is driven by a seated person's operation from the state shown in FIG. 24A and the seat cushion frame F1 (seat cushion S21) is moved forward, the seat cushion frame F1 is moved to the seat cushion frame F1. By being pulled, the lower end portion of the lower frame 20 of the seat back frame F2 moves forward. As a result, the lower frame 20 moves downward while rotating forward about the axis A2, thereby lowering the upper frame 10, and the upper frame 10 is moved downward with respect to the back panel 60 by the moving mechanism M. To do. As a result, as shown in FIG. 24 (b), the seat back S22 falls to the rear with respect to the seat cushion S21. At this time, as the seat back S22 moves from the initial position shown in FIG. 24 (a) to the lower position shown in FIG. 24 (b), the armrest S24 rotates the lower frame 20 forward about the axis A2. By moving downward while moving, as shown in FIG. 22, FIG. 25 (a) and FIG.
　一方、図２４（ｂ）に示す状態から、アクチュエータＡＣを駆動させ、シートクッションフレームＦ１を後ろに向けて移動させると、シートクッションフレームＦ１に押されて、シートバックフレームＦ２の下部フレーム２０の下端部が後ろに移動する。これにより、下部フレーム２０が軸Ａ２を中心に後ろに回動しながら上方に移動することで、上部フレーム１０を上に押し上げ、上部フレーム１０が移動機構Ｍによってバックパネル６０に対して上に移動する。この結果、図２４（ａ）に示すように、シートバックＳ２２は、シートクッションＳ２１に対して起きた状態となる。このとき、アームレストＳ２４は、シートバックＳ２２が図２４（ｂ）に示す下方位置から図２４（ａ）に示す初期位置に移動するのに伴って、下部フレーム２０が軸Ａ２を中心に後ろに回動しながら上方に移動することで、図２５（ｂ）、図２５（ａ）および図２２と順に示すように、後ろ斜め上方に向けて移動する。 On the other hand, when the actuator AC is driven and the seat cushion frame F1 is moved backward from the state shown in FIG. 24B, the lower end of the lower frame 20 of the seat back frame F2 is pushed by the seat cushion frame F1. The part moves backward. As a result, the lower frame 20 moves upward while pivoting about the axis A 2, thereby pushing up the upper frame 10, and the upper frame 10 is moved upward with respect to the back panel 60 by the moving mechanism M. To do. As a result, as shown in FIG. 24A, the seat back S22 is raised with respect to the seat cushion S21. At this time, as the seat back S22 moves from the lower position shown in FIG. 24 (b) to the initial position shown in FIG. 24 (a), the armrest S24 rotates the lower frame 20 backward about the axis A2. By moving upward while moving, as shown in order of FIG. 25B, FIG. 25A, and FIG.
　以上説明した本実施形態によれば、図２２に示したように、収納状態のアームレストＳ２４の下端と収納部Ｈ１の下側対向面Ｇ１との間に空間ＳＰ１が設けられているので、図２５（ａ），（ｂ）に示すように、シートバックＳ２２の初期位置から下方位置への移動に伴って、アームレストＳ２４が前斜め下方に移動しても、アームレストＳ２４が下側対向面Ｇ１にぶつかることはない。これにより、シートバックＳ２２が下方位置に移動するときのアームレストＳ２４と、収納部Ｈ１が形成されたシートバックＳ１２の干渉を抑制することができる。 According to the present embodiment described above, as shown in FIG. 22, the space SP1 is provided between the lower end of the armrest S24 in the storage state and the lower facing surface G1 of the storage portion H1, so FIG. As shown in (a) and (b), as the seat back S22 moves from the initial position to the lower position, the armrest S24 hits the lower facing surface G1 even if the armrest S24 moves diagonally forward and downward. There is nothing. Thereby, interference of armrest S24 when seat back S22 moves to a lower position and seat back S12 in which storage part H1 was formed can be controlled.
　また、本実施形態では、シートバックＳ２２の初期位置から下方位置への移動に伴って、前斜め下方に移動するアームレストＳ２４の下端の移動軌跡に沿うように、下側対向面Ｇ１が前斜め下方に向けて傾斜しているので、アームレストＳ２４との干渉を抑制しつつ、空間ＳＰ１を小さくすることができる。これにより、アームレストＳ２４と下側対向面Ｇ１との間に空間ＳＰ１を有する車両用シートＳにおいて、見栄えを良くすることができる。 Further, in the present embodiment, the lower facing surface G1 is inclined obliquely forward and downward so as to follow the movement trajectory of the lower end of the armrest S24 that moves obliquely forward and downward as the seat back S22 moves from the initial position to the downward position. Therefore, the space SP1 can be reduced while suppressing interference with the armrest S24. Thereby, in the vehicle seat S having the space SP1 between the armrest S24 and the lower facing surface G1, the appearance can be improved.
　また、本実施形態では、図１８に示したように、上下に移動可能なシートバックＳ２２，Ｓ３２が、車体に対して動かないシートバックＳ１２の両側に隣接して設けられているが、収納部Ｈ２が収納部Ｈ１と同様の構成を有しているので、シートバックＳ３２が下方位置に移動するときのアームレストＳ３４と、収納部Ｈ２が形成されたシートバックＳ１２の干渉を抑制することができる。 Further, in the present embodiment, as shown in FIG. 18, seat backs S22 and S32 that are movable up and down are provided adjacent to both sides of the seat back S12 that does not move relative to the vehicle body. Since H2 has the same configuration as the storage portion H1, it is possible to suppress interference between the armrest S34 when the seatback S32 moves to the lower position and the seatback S12 in which the storage portion H2 is formed.
　また、本実施形態では、上下に移動可能なシートバックＳ２２の両側に、車体に対して動かないシートバックＳ１２と左サイド部Ｓ４が隣接して設けられているが、収納部Ｈ３が収納部Ｈ１と同様の構成を有しているので、シートバックＳ２２が下方位置に移動するときのアームレストＳ２５と、収納部Ｈ３が形成された左サイド部Ｓ４の干渉を抑制することができる。右サイド部Ｓ５側についても同様である。 In the present embodiment, the seat back S12 that does not move relative to the vehicle body and the left side portion S4 are provided adjacent to both sides of the seat back S22 that can move up and down, but the storage portion H3 is the storage portion H1. Therefore, the interference between the armrest S25 when the seat back S22 moves to the lower position and the left side portion S4 where the storage portion H3 is formed can be suppressed. The same applies to the right side portion S5 side.

Thereby, the moving mechanism 100 is attached to the seat back frame F2.
　ガイドバー１０１が固定された第１ブラケット１５０と、第２ブラケット１６０とが連結された状態において、ガイドバー１０１は、その上端部が第２ブラケット１６０の補強板固定部１６３の前側の面に当接している。これにより、ガイドバー１０１の上端部を後ろからブラケット１０３で支えることができるとともに、補強板固定部１６３がガイド筒１０２に引っ掛かることでガイドバー１０１がブラケット１０３ごとガイド筒１０２から抜け落ちてしまうことを抑制することができる。また、シートバックフレームＦ２に移動機構１００が取り付けられた状態において、補強板１０４の補強部１４２の前端は、シートフレームパネル６５０の背面に当接している。 In the state where the first bracket 150 to which the guide bar 101 is fixed and the second bracket 160 are connected, the upper end of the guide bar 101 abuts against the front surface of the reinforcing plate fixing portion 163 of the second bracket 160. It touches. As a result, the upper end of the guide bar 101 can be supported by the bracket 103 from behind, and the guide bar 101 can be detached from the guide cylinder 102 together with the bracket 103 by the reinforcement plate fixing portion 163 being caught by the guide cylinder 102. Can be suppressed. Further, in a state where the moving mechanism 100 is attached to the seat back frame F2, the front end of the reinforcing portion 142 of the reinforcing plate 104 is in contact with the back surface of the seat frame panel 650.
　図３３および図３４に示すように、バックパネル６０は、プレス加工して成形された板金からなり、車両用シートＳ（右シートＳＲおよび左シートＳＬ）の後ろに対向して配置されている（図１も参照）。本実施形態において、バックパネル６０は、車体に固定されており、車体の一部を構成している。バックパネル６０には、前後に貫通する開口６３Ｃが形成されており、開口６３Ｃには、シート取付ブラケット７０が当該開口６３Ｃに入り込んだ状態で配置されている。 As shown in FIGS. 33 and 34, the back panel 60 is made of a sheet metal formed by pressing, and is disposed to face the back of the vehicle seat S (the right seat SR and the left seat SL) ( (See also FIG. 1). In the present embodiment, the back panel 60 is fixed to the vehicle body and constitutes a part of the vehicle body. The back panel 60 has an opening 63 </ b> C penetrating in the front-rear direction, and the seat mounting bracket 70 is disposed in the opening 63 </ b> C so as to enter the opening 63 </ b> C.
　シート取付ブラケット７０は、プレス加工して成形された板金からなり、開口６３Ｃの周囲で図示しないボルトなどによって締結されることで、バックパネル６０に固定されている。バックパネル６０に取り付けられるシート取付ブラケット７０には、前側の面に、フック係合部７１が設けられている。 The sheet mounting bracket 70 is made of a sheet metal formed by pressing, and is fixed to the back panel 60 by being fastened by a bolt or the like (not shown) around the opening 63C. The seat mounting bracket 70 attached to the back panel 60 is provided with a hook engaging portion 71 on the front surface.
　フック係合部７１は、フック１７０が係合する部分であり、金属製の棒状の部材からなる。より詳細に、フック係合部７１は、金属製の棒状の部材を略Ｕ字形状に屈曲し、その両端が溶接などによってシート取付ブラケット７０の前側の面に固定されている。これにより、フック係合部７１は、シート取付ブラケット７０を介して、バックパネル６０に固定されている。フック係合部７１は、上側に配置された２つのフック１７０と、下側に配置された２つのフック１７０に対応して、上下に離れて２つ設けられている。 The hook engaging portion 71 is a portion with which the hook 170 is engaged, and is made of a metal rod-like member. More specifically, the hook engaging portion 71 is formed by bending a metal rod-like member into a substantially U shape, and both ends thereof are fixed to the front surface of the seat mounting bracket 70 by welding or the like. Thereby, the hook engaging portion 71 is fixed to the back panel 60 via the seat mounting bracket 70. Two hook engaging portions 71 are provided apart from each other in the vertical direction, corresponding to the two hooks 170 disposed on the upper side and the two hooks 170 disposed on the lower side.
　次に、左シートＳＬの車体への取り付けについて簡単に説明する。
　左シートＳＬを車体に取り付けるときには、まず、シートバックＳ２０をバックパネル６０に取り付ける。具体的には、図３３に示すように、シートバックＳ２０に設けられた移動機構１００の高さ位置と、バックパネル６０に設けられたシート取付ブラケット７０の高さ位置とを合わせつつ、上側の２つのフック１７０を上側のフック係合部７１に係合し、下側の２つのフック１７０を下側のフック係合部７１に係合する。これにより、シートバックＳ２０がバックパネル６０に取り付けられる。次に、図３５（ａ）に示すように、シートクッションＳ１０を車体のフロア（符号省略）に取り付ける。そして、ヘッドレストＳ３０をシートバックＳ２０に取り付けることで、左シートＳＬが車体に取り付けられる。 Next, the attachment of the left seat SL to the vehicle body will be briefly described.
When attaching the left seat SL to the vehicle body, first, the seat back S20 is attached to the back panel 60. Specifically, as shown in FIG. 33, the height position of the moving mechanism 100 provided in the seat back S20 and the height position of the seat mounting bracket 70 provided in the back panel 60 are matched, The two hooks 170 are engaged with the upper hook engaging portion 71, and the lower two hooks 170 are engaged with the lower hook engaging portion 71. Accordingly, the seat back S20 is attached to the back panel 60. Next, as shown in FIG. 35A, the seat cushion S10 is attached to the floor (reference number omitted) of the vehicle body. Then, the left seat SL is attached to the vehicle body by attaching the headrest S30 to the seat back S20.
　次に、左シートＳＬのリクライニング動作について説明する。
　図３５（ａ）に示す状態から、着座者の操作などによってアクチュエータＡＣ（図３０参照）を駆動させ、シートクッションフレームＦ１（シートクッションＳ１０）を前に向けて移動させると、図３５（ｂ）に示すように、シートクッションフレームＦ１に引っ張られて、シートバックフレームＦ２の下部フレーム２０の下端部が前に移動する。これにより、下部フレーム２０が軸Ａ２を中心に前に回動しながら下方に移動することで、上部フレーム１０を下に引き下げ、上部フレーム１０が移動機構１００によってバックパネル６０に対して下にスライド移動する。その結果、シートバックＳ２０は、シートクッションＳ１０に対して後方に倒れた状態（リクライニング状態）となる。 Next, the reclining operation of the left seat SL will be described.
When the actuator AC (see FIG. 30) is driven by a seated person's operation or the like from the state shown in FIG. 35 (a) and the seat cushion frame F1 (seat cushion S10) is moved forward, FIG. 35 (b) As shown in FIG. 2, the lower end portion of the lower frame 20 of the seat back frame F2 is moved forward by being pulled by the seat cushion frame F1. As a result, the lower frame 20 moves downward while rotating forward about the axis A <b> 2, thereby lowering the upper frame 10, and the upper frame 10 is slid downward with respect to the back panel 60 by the moving mechanism 100. Moving. As a result, the seat back S20 is in a state of being tilted backward (reclining state) with respect to the seat cushion S10.
　一方、リクライニング状態から、アクチュエータＡＣを駆動させ、シートクッションフレームＦ１を後ろに向けて移動させると、図３５（ａ）に示すように、シートクッションフレームＦ１に押されて、シートバックフレームＦ２の下部フレーム２０の下端部が後ろに移動する。これにより、下部フレーム２０が軸Ａ２を中心に後ろに回動しながら上方に移動することで、上部フレーム１０を上に押し上げ、上部フレーム１０が移動機構１００によってバックパネル６０に対して上にスライド移動する。この結果、シートバックＳ２０は、シートクッションＳ１０に対して起きた状態となる。 On the other hand, when the actuator AC is driven from the reclining state and the seat cushion frame F1 is moved rearward, as shown in FIG. 35 (a), it is pushed by the seat cushion frame F1, and the lower portion of the seat back frame F2 The lower end of the frame 20 moves backward. As a result, the lower frame 20 moves upward while rotating backward about the axis A 2, thereby pushing up the upper frame 10, and the upper frame 10 is slid upward with respect to the back panel 60 by the moving mechanism 100. Moving. As a result, the seat back S20 is raised with respect to the seat cushion S10.
　以上説明した本実施形態によれば、左シートＳＬの一部である移動機構１００に設けられたフック１７０を、バックパネル６０にシート取付ブラケット７０を介して設けられたフック係合部７１に係合することで、バックパネル６０と移動機構１００（左シートＳＬ）を簡単に組み付けることができる。 According to the present embodiment described above, the hook 170 provided on the moving mechanism 100 that is a part of the left seat SL is engaged with the hook engaging portion 71 provided on the back panel 60 via the seat mounting bracket 70. By combining, the back panel 60 and the moving mechanism 100 (left sheet SL) can be easily assembled.
　また、移動機構１００がブラケット１０３に固定される補強板１０４を備えるので、補強板１０４によってバックパネル６０に固定される板状のブラケット１０３の撓みを抑制することができる。これにより、移動機構１００の歪みが抑制され、ガイドバー１０１とガイド筒１０２とが良好に摺動可能となるので、シートバックＳ２０を良好に上下動させることができる。 Moreover, since the moving mechanism 100 includes the reinforcing plate 104 that is fixed to the bracket 103, the bending of the plate-like bracket 103 that is fixed to the back panel 60 by the reinforcing plate 104 can be suppressed. Thereby, distortion of the moving mechanism 100 is suppressed, and the guide bar 101 and the guide cylinder 102 can be slid satisfactorily, so that the seat back S20 can be moved up and down satisfactorily.
　また、１部品たる連結ブラケット６３０の左右のブラケット延出部６３２に、縦フレーム部１１の下端部が固定され、下部サイドフレーム２１の上端部が軸Ａ２を中心に回動可能に支持されているので、縦フレーム部の下端部と下部サイドフレームの上端部とを左右で独立して回動可能に連結する構成と比較して、シートバックフレームＦ２が歪みにくくなる。これにより、シートバックＳ２０を良好に中折れさせることができるので、シートバックＳ２０を良好に上下動させることができる。 Also, the lower end of the vertical frame portion 11 is fixed to the left and right bracket extending portions 632 of the connection bracket 630 as one component, and the upper end portion of the lower side frame 21 is supported so as to be rotatable about the axis A2. Therefore, the seat back frame F <b> 2 is less likely to be distorted compared to a configuration in which the lower end portion of the vertical frame portion and the upper end portion of the lower side frame are connected to be independently rotatable on the left and right. As a result, the seat back S20 can be folded well, and the seat back S20 can be moved up and down well.
　また、縦フレーム部１１が上下にまっすぐ延びるパイプからなるので、縦フレーム部が左右方向の内側や外側に凹むように屈曲する構成と比較して、シートバックフレームＦ２の構成を簡略化することができる。これにより、例えば、シートバックフレームＦ２を製造する際の、工数を減らしたり、コストを抑えたりすることができる。 Further, since the vertical frame portion 11 is made of a pipe that extends straight up and down, the configuration of the seat back frame F2 can be simplified as compared with a configuration in which the vertical frame portion is bent so as to be recessed inward or outward in the left-right direction. it can. Thereby, for example, the man-hour when manufacturing the seat back frame F2 can be reduced, or the cost can be suppressed.
　また、フック１７０が、左右に離れて２つ設けられ、また、上下に離れて２つ設けられているので、フックが１つだけ設けられるような構成と比較して、移動機構１００をバックパネル６０に対して安定した状態に取り付けることができる。これにより、シートバックＳ２０をより良好に上下動させることができる。特に、本実施形態では、４つのフック１７０が互いに離れて四角形の角の位置に配置されているので、移動機構１００をバックパネル６０に取り付けたときに、バックパネル６０に対する移動機構１００のがたつきを抑制することができる。これにより、移動機構１００をバックパネル６０に対してより安定した状態に取り付けることができるので、シートバックＳ２０をより一層良好に上下動させることができる。 Further, two hooks 170 are provided apart from each other on the left and right sides, and two hooks 170 are provided apart from each other up and down, so that the moving mechanism 100 is provided with the back panel as compared with a configuration in which only one hook is provided. 60 can be attached in a stable state. Thereby, seat back S20 can be moved up and down more favorably. In particular, in the present embodiment, the four hooks 170 are separated from each other and disposed at the corners of the square, so that when the moving mechanism 100 is attached to the back panel 60, the back of the moving mechanism 100 with respect to the back panel 60 Suppression can be suppressed. Thereby, since the moving mechanism 100 can be attached to the back panel 60 in a more stable state, the seat back S20 can be moved up and down even better.
　以上、実施形態について説明したが、本発明は前記実施形態に限定されるものではない。具体的な構成については、下記のように発明の趣旨を逸脱しない範囲で適宜変更が可能である。 As mentioned above, although embodiment was described, this invention is not limited to the said embodiment. About a concrete structure, it can change suitably in the range which does not deviate from the meaning of invention as follows.
　前記第１実施形態では、バックパネル６０は、凹部６３が、その上縁部６３ＡにシートバックＳ２０の上端ＳＴを合わせることで、フレーム側部材３０とパネル側部材４０とを係合可能な位置に位置合わせするように設けられていたが、これに限定されるものではない。例えば、図３６（ａ）に示すように、バックパネル６０は、シートバックＳ２０をバックパネル６０に取り付けるときに、シートバックＳ２０の上端ＳＴを合わせることで、フレーム側部材３０とパネル側部材４０とを係合可能な位置に位置合わせする目印６５を有する構成であってもよい。より具体的には、目印６５は、凹部６３の上に形成され、上下方向において、当該目印６５からパネル側部材４０の係合部４１の下端まで間隔Ｄ３が、シートバックＳ２０の上端ＳＴからフレーム側部材３０の被ガイド部３１の上端まで間隔Ｄ４よりも小さくなるように設けられている。 In the first embodiment, the back panel 60 has the recess 63 in a position where the frame side member 30 and the panel side member 40 can be engaged by aligning the upper end ST of the seat back S20 with the upper edge portion 63A. Although it was provided so that it may align, it is not limited to this. For example, as shown in FIG. 36A, when the seat back S20 is attached to the back panel 60, the back panel 60 is aligned with the upper end ST of the seat back S20, so that the frame side member 30 and the panel side member 40 It may be configured to have a mark 65 for aligning the position to the position where it can be engaged. More specifically, the mark 65 is formed on the recess 63, and in the vertical direction, a distance D3 from the mark 65 to the lower end of the engaging portion 41 of the panel side member 40 is a frame from the upper end ST of the seat back S20. The upper end of the guided portion 31 of the side member 30 is provided to be smaller than the interval D4.
　このような構成によれば、シートバックＳ２０の上端ＳＴの高さ位置を目印６５の位置に合わせることで、上下方向において、被ガイド部３１の上端を係合部４１の下端よりも下に配置することができる。これにより、図３６（ｂ）に示すように、凹部６３内のパネル側部材４０の下のスペースにフレーム側部材３０を収めて、フレーム側部材３０をパネル側部材４０の下から係合させるときに、フレーム側部材３０をパネル側部材４０に係合しやすくなるので、シートバックＳ２０をバックパネル６０に取り付けるときの作業性を向上させることができる。なお、図３６では、目印の一例として、シート対向面６１に対して凹む形状の目印６５を示しているが、これに限定されず、例えば、目印は、シート対向面に対して突出する形状であってもよい。また、目印は、シート対向面にラインなどを描くことで形成してもよいし、シート対向面にシールなどを貼り付けて形成してもよい。 According to such a configuration, by aligning the height position of the upper end ST of the seat back S20 with the position of the mark 65, the upper end of the guided portion 31 is disposed below the lower end of the engaging portion 41 in the vertical direction. can do. Thereby, as shown in FIG. 36B, when the frame side member 30 is stored in the space below the panel side member 40 in the recess 63 and the frame side member 30 is engaged from below the panel side member 40. Furthermore, since it becomes easy to engage the frame side member 30 with the panel side member 40, workability | operativity when attaching seat back S20 to the back panel 60 can be improved. In FIG. 36, as an example of the mark, the mark 65 having a shape recessed with respect to the sheet facing surface 61 is shown. However, the present invention is not limited to this.
