本発明の実施例の車両用シート装置1は、以上のように構成されるから、車両フロア5に設置された標準チルト姿勢のシート取付部材4の手動ハンドル61を持ち、かつロック解除レバー18を握るとロック解除レバー18に繋がる第1連結ワイヤー19が引っ張られて回転ロック部材16のフック部16bがベース部材2に一体に設けられた回転ロック受けプレート12の格納位置ロック孔12aから外れ、回転ロックが解除される。そこで、横向回転をさせることができる。 Since the vehicle seat device 1 of the embodiment of the present invention is configured as described above, it has a manual handle 61 of the seat mounting member 4 in the standard tilt posture installed on the vehicle floor 5 and has an unlock lever 18. When grasped, the first connecting wire 19 connected to the lock release lever 18 is pulled, and the hook portion 16b of the rotation lock member 16 is disengaged from the storage position lock hole 12a of the rotation lock receiving plate 12 integrally provided with the base member 2 and rotates. The lock is released. Therefore, the lateral rotation can be performed.

手動ハンドル61を持ち、シート取付部材4を横向方向に回転し、ロック解除レバー18から手を離すと、回転ロック部材16のフック部16bが牽引バネ17により牽引され、フック部16bの先端係合部16b1が回転ロック受けプレート12の外周面を摺擦し、横向回転途中位置ロック孔12bに対応すると自動的に嵌合して回転をロックする。また、この位置で、下降位置Y2にある内側作動規制ピン14aが内側作動規制プレート13aの後側途中衝突部13a2と衝突し、回転を停止させる。 When the manual handle 61 is held, the seat mounting member 4 is rotated in the lateral direction, and the lock release lever 18 is released, the hook portion 16b of the rotary lock member 16 is pulled by the traction spring 17, and the tip of the hook portion 16b is engaged. When the portion 16b1 rubs the outer peripheral surface of the rotation lock receiving plate 12 and corresponds to the lateral rotation intermediate position lock hole 12b, the portion 16b1 is automatically fitted to lock the rotation. Further, at this position, the inner operation restricting pin 14a at the descending position Y2 collides with the rear side intermediate collision portion 13a2 of the inner operation restricting plate 13a to stop the rotation.

再び、手動ハンドル61を持ち、ロック解除レバー18を握り、回転ロック部材16のフック部16bを横向回転途中位置ロック孔12bから外し、ロック解除レバー18とチルトロック部材39を繋いでいる第2連結ワイヤー47を引張ると、チルトロック部材39はチルトロック軸38を中心にロックバネ40に抗して解除方向へ回動し、ロックピン41を標準姿勢ロック溝42aから外れる。そこで、その状態で手動ハンドル61を持ってシート取付部材4を、図7に示すように、シート取付部材4の左側チルトガイドプレート29aの左前半ガイド孔30aと左後半ガイド孔31aは左チルトブラケット21aの左前半ガイドローラ22aと左後半ガイドローラ23aによって一点を中心とする半径回りに前後にスライドし、同じくシート取付部材4の右側チルトガイドプレート29bも同様に支承されて一点を中心とする半径回りに前後にスライドし、前上がりチルト姿勢に作動させる。前上がりチルト姿勢の作動終了時にロック解除レバー18を離せば、ロックピン41が前上がり姿勢ロック溝42bに対応しているので、そのロック溝42bに嵌合させ、前上がりチルト姿勢の作動状態にロックが掛かかる。このシート取付部材4が前上がりチルト姿勢に回動すると、前記内側作動規制ピン14aが上昇位置Y1に移動して後側途中衝突部13a2との衝突を解消する。そして、回転ロック部材16のフック部16bを横向回転途中位置ロック孔12bに再び嵌合して回転ロックをするとできる。しかし、ここでは、ロック解除レバー18を握った状態で横向きに僅かに回転して回転ロック部材16のフック部16bを横向回転途中位置ロック孔12bより横向き方向にずらしたところでロック解除レバー18を離し、ロックピン41を前上がり姿勢ロック溝42bに嵌合させて前上がりチルト姿勢の作動状態にロックを掛け、回転ロック部材16のフック部16bの先端係合部16b1を回転ロック受けプレート12の外周面を摺擦させる。そこで、シート取付部材4を車外繰出し横向回転をすることができる。 Again, hold the manual handle 61, grasp the lock release lever 18, remove the hook portion 16b of the rotation lock member 16 from the lateral rotation intermediate position lock hole 12b, and connect the lock release lever 18 and the tilt lock member 39 to the second connection. When the wire 47 is pulled, the tilt lock member 39 rotates around the tilt lock shaft 38 in the release direction against the lock spring 40, and the lock pin 41 is disengaged from the standard posture lock groove 42a. Therefore, in that state, the seat mounting member 4 is held by the manual handle 61, and as shown in FIG. 7, the left front half guide hole 30a and the left rear half guide hole 31a of the left tilt guide plate 29a of the seat mounting member 4 are left tilt brackets. The left front half guide roller 22a and the left rear half guide roller 23a of 21a slide back and forth around a radius centered on one point, and the right tilt guide plate 29b of the seat mounting member 4 is also supported in the same manner and has a radius centered on one point. Slide back and forth around to operate in a forward tilted posture. If the lock release lever 18 is released at the end of the operation of the forward upward tilt posture, the lock pin 41 corresponds to the forward upward tilt posture lock groove 42b. It locks. When the seat mounting member 4 rotates in the forward ascending tilt posture, the inner operation restricting pin 14a moves to the ascending position Y1 to eliminate the collision with the rear side intermediate collision portion 13a2. Then, the hook portion 16b of the rotation lock member 16 can be refitted into the lateral rotation intermediate position lock hole 12b to lock the rotation. Here, however, release the lock release lever 18 at shifted hook portion 16b of the rotation lock member 16 slightly rotates sideways while gripping the lock release lever 18 transversely direction from YokoMuko rotational middle position locking hole 12b , The lock pin 41 is fitted into the forward upward tilt posture lock groove 42b to lock the operating state of the forward upward tilt posture, and the tip engaging portion 16b1 of the hook portion 16b of the rotary lock member 16 is placed on the outer periphery of the rotary lock receiving plate 12. Rub the surface. Therefore, the seat mounting member 4 can be extended out of the vehicle and rotated sideways.

手動ハンドル61を持ってシート取付部材4を回転し、横向位置に達すると、回転部材3の上面に配備された回転規制長孔62の横向位置停止面63bがインナーベアリング7aの上面に立設した停止ピン64に衝突して停止し、横向回転が完了する。ここでも、ロック解除レバー18を離していると、回転ロック部材16のフック部16bは、自動的に横向位置ロック孔12cに嵌合して回転をロックする。それから、手動ハンドル61を持ち、ロック解除レバー18を握り、ロック解除レバー18と連繋するチルトロック部材39を、チルトロック軸38を中心にロックバネ40に抗して解除方向へ回動し、ロックピン41を前上がり姿勢ロック溝42bから外し、その状態で手動ハンドル61を持ってシート取付部材4を、図9に示すように、シート取付部材4の左側チルトガイドプレート29aと右側チルトガイドプレート29bの姿勢チルト手段10により一点を中心とする半径回りに前後にスライドし、前下がりチルト姿勢に作動させる。前下がりチルト姿勢へ作動の終了時にロック解除レバー18を離せば、ロックピン41が前下がり姿勢ロック溝42cに対応しているので、その前下がり姿勢ロック溝42cに嵌合させ、前下がりチルト姿勢の状態にロックが掛かかる。 When the seat mounting member 4 is rotated by holding the manual handle 61 and reaches the lateral position, the lateral position stop surface 63b of the rotation restricting elongated hole 62 provided on the upper surface of the rotating member 3 stands on the upper surface of the inner bearing 7a. It collides with the stop pin 64 and stops, and the lateral rotation is completed. Again, when the lock release lever 18 is released, the hook portion 16b of the rotation lock member 16 automatically fits into the lateral position lock hole 12c to lock the rotation. Then, holding the manual handle 61, grasping the lock release lever 18, the tilt lock member 39 connected to the lock release lever 18 is rotated around the tilt lock shaft 38 against the lock spring 40 in the release direction, and the lock pin is With the 41 removed from the forward rising posture lock groove 42b and the manual handle 61 in that state, the seat mounting member 4 is attached to the left tilt guide plate 29a and the right tilt guide plate 29b of the seat mounting member 4, as shown in FIG. The posture tilt means 10 slides back and forth around a radius centered on one point to operate the posture tilting forward. When the lock release lever 18 is released at the end of the operation to the forward lowering tilt posture, the lock pin 41 corresponds to the forward lowering posture lock groove 42c. The state of is locked.

シート取付部材4が前下がりチルト姿勢へ作動時に内側作動規制ピン14aは下降位置Y2へ移動し、その前下がりチルト姿勢で車内へ格納回転をすると、内側作動規制ピン14aが前側衝突部13a3と衝突して回動が抑止される。 When the seat mounting member 4 operates in the forward downward tilt posture, the inner operation regulation pin 14a moves to the lower position Y2, and when the seat mounting member 4 retracts and rotates in the vehicle in the forward downward tilt posture, the inner operation regulation pin 14a collides with the front collision portion 13a3. Then the rotation is suppressed.

次に、車内へ格納回転時は、先ず、シート取付部材4を前下がりチルト姿勢から前上がりチルト姿勢への作動は、手動ハンドル61を持ち、ロック解除レバー18を握り、回転ロック部材16のフック部16bを横向位置ロック孔12cから外し、チルトロック部材39を、チルトロック軸38を中心にロックバネ40に抗して解除方向へ回動し、ロックピン41を前下がり姿勢ロック溝42cから外し、その状態で手動ハンドル61を持ってシート取付部材4を、図9に示すように、シート取付部材4の左側チルトガイドプレート29aと右側チルトガイドプレート29bの姿勢チルト手段10により一点を中心とする半径回りに前後にスライドし、前上がりチルト姿勢に作動させる。前上がりチルト姿勢の作動終了時にロック解除レバー18を離せば、ロックピン41が前上がり姿勢ロック溝42bに対応しているので、その前上がり姿勢ロック溝42bに嵌合し、前上がりチルト姿勢の作動状態にロックが掛かかる。 Next, when the seat mounting member 4 is retracted and rotated in the vehicle, the operation of the seat mounting member 4 from the forward downward tilt posture to the forward upward tilt posture is performed by holding the manual handle 61, gripping the lock release lever 18, and hooking the rotation lock member 16. The portion 16b is removed from the lateral position lock hole 12c, the tilt lock member 39 is rotated around the tilt lock shaft 38 in the release direction against the lock spring 40, and the lock pin 41 is removed from the forward lowering posture lock groove 42c. In that state, hold the manual handle 61 and move the seat mounting member 4 around one point by the posture tilt means 10 of the left tilt guide plate 29a and the right tilt guide plate 29b of the seat mounting member 4, as shown in FIG. Slide back and forth around to operate in a forward tilted posture. If the lock release lever 18 is released at the end of the operation of the forward-up tilt posture, the lock pin 41 corresponds to the front-up posture lock groove 42b. The operating state is locked.

前記内側作動規制ピン14aは、シート取付部材4の前上がりチルト姿勢への作動により上昇位置Y1に移動して前側衝突部13a3の衝突が自動的に解消するから、手動ハンドル61を持ってロック解除レバー18を握り、シート取付部材4を前上がりチルト姿勢の状態で回転部材3と共に車内へ格納回転をすることができる。シート取付部材4が前上がりチルト姿勢の状態で回転格納位置に近づくと、下降位置Y2に移動した外側作動規制ピン14bが標準チルト復帰用衝突部13b1に衝突するので、シート取付部材4は回転を停止する。ここでもロック解除レバー18を離していると、回転ロック部材16のフック部16bは、自動的に横向回転途中位置ロック孔12bに嵌合して回転をロックする。そこで、シート取付部材4を前上がりチルト姿勢から標準チルト姿勢へチルト作動を行う。すると、外側作動規制ピン14bは、標準チルト復帰用衝突部13b1より上昇位置Y1に移動し、衝突を解消する。そこで、再び、ロック解除レバー18を握り、回転ロック部材16のフック部16bを横向回転途中位置ロック孔12bから外して回転ロックを解消し、手動ハンドル61を持ってシート取付部材4を回転格納位置に回転し、回転部材3の上面に配備された回転規制長孔62の格納位置停止面63aが回転ベアリング7の上面に立設した停止ピン64に衝突して停止する。そこで、ロック解除レバー18を操作していなければ、回転ロック部材16のフック部16bは自動的に格納位置ロック孔12aに嵌合してシート取付部材4の回転をロックし、回転格納位置に保持する。 The inner operation restricting pin 14a moves to the ascending position Y1 by the operation of the seat mounting member 4 in the forward ascending tilt posture, and the collision of the front collision portion 13a3 is automatically eliminated. Therefore, the lock is released by holding the manual handle 61. The lever 18 can be gripped, and the seat mounting member 4 can be retracted and rotated in the vehicle together with the rotating member 3 in a forward tilted posture. When the seat mounting member 4 approaches the rotation storage position in the forward rising tilt posture, the outer operation restricting pin 14b moved to the descending position Y2 collides with the standard tilt return collision portion 13b1, so that the seat mounting member 4 rotates. Stop. Again, when the lock release lever 18 is released, the hook portion 16b of the rotation lock member 16 automatically fits into the lateral rotation intermediate position lock hole 12b to lock the rotation. Therefore, the seat mounting member 4 is tilted from the forward tilted posture to the standard tilted posture. Then, the outer operation restricting pin 14b moves from the standard tilt return collision portion 13b1 to the ascending position Y1 to eliminate the collision. Therefore, the lock release lever 18 is grasped again, the hook portion 16b of the rotation lock member 16 is removed from the lateral rotation intermediate position lock hole 12b to release the rotation lock, and the seat mounting member 4 is rotated and stored by holding the manual handle 61. The storage position stop surface 63a of the rotation regulation elongated hole 62 provided on the upper surface of the rotating member 3 collides with the stop pin 64 erected on the upper surface of the rotary bearing 7 and stops. Therefore, if the lock release lever 18 is not operated, the hook portion 16b of the rotation lock member 16 automatically fits into the storage position lock hole 12a to lock the rotation of the seat mounting member 4 and hold it in the rotation storage position. do.

本発明の実施例では、利便性の向上(レバーの持ち替えがない。)を目的として回転ロック解除とチルトロック解除を同一レバーにて行う仕様となっているが別々の解除レバーを構成してもよいものである。 In the embodiment of the present invention, the rotation lock release and the tilt lock release are performed by the same lever for the purpose of improving convenience (the lever is not changed), but even if separate release levers are configured. It's a good one.

本発明の実施例の車両用シート装置1では、図18に示すように、姿勢チルト手段10は、左側チルトガイドプレート29aの左前半ガイド孔30aと左後半ガイド孔31a及び右側チルトガイドプレート29bの右前半ガイド孔30bと右後半ガイド孔31bが、チルト中心軸Pを中心とする半径R1の内径側円弧形軸受面32aと同じくチルト中心軸Pを中心とする半径R2の外径側円弧形軸受面32bにより夫々形成されるから、該左前半ガイド孔30aと左後半ガイド孔31aに嵌合する左前半ガイドローラ22aと左後半ガイドローラ23a及び該右前半ガイド孔30bと右後半ガイド孔31bに嵌合する嵌合する右前半ガイドローラ22bと右後半ガイドローラ23bは、夫々を支点にチルト作動し、それらの標準チルト姿勢の重心G1、前上がりチルト姿勢の重心G2及び前下がりチルト姿勢の重心G3と移動の範囲が僅かな移動範囲に納まっている。このことは、手動ハンドルを持って操作する操作力が少なくて済むことを実証するものである。こかれが、図19に示す従来の姿勢チルト手段(引用文献2)によると、チルト中心軸P1に対して標準チルト姿勢の重心位置g1、前上がりチルト姿勢の重心位置g2及び前下がりチルト姿勢の重心位置g3となり、チルト中心軸P1に対して大きく離れ、手動ハンドルによる操作力が大きく増大する欠点があった。 In the vehicle seat device 1 of the embodiment of the present invention, as shown in FIG. 18, the posture tilting means 10 is a left front half guide hole 30a, a left rear half guide hole 31a, and a right side tilt guide plate 29b of the left tilt guide plate 29a. The right front half guide hole 30b and the right second half guide hole 31b are arcuate on the inner diameter side of the radius R1 centered on the tilt center axis P. Since the shape bearing surface 32b is formed respectively, the left front half guide roller 22a and the left rear half guide roller 23a, and the right front half guide hole 30b and the right rear half guide hole that fit into the left front half guide hole 30a and the left rear half guide hole 31a are formed. The right front half guide roller 22b and the right rear half guide roller 23b that fit into 31b are tilted with their respective fulcrums as fulcrums, and their standard tilt posture center of gravity G1, forward ascending tilt posture center of gravity G2, and front falling tilt posture. The center of gravity G3 and the range of movement are within a small range of movement. This demonstrates that the operating force of holding and operating the manual handle is small. According to the conventional posture tilting means (Reference 2) shown in FIG. 19, the center of gravity position g1 of the standard tilt posture, the center of gravity position g2 of the forward rising tilt posture, and the forward falling tilt posture with respect to the tilt central axis P1. There is a drawback that the position of the center of gravity is g3, which is far away from the tilt center axis P1 and the operating force of the manual handle is greatly increased.

本発明の車両用シート装置は、ドア開口部よりも低い位置に足乗せ台を設定して良好な標準乗車姿勢を確保し、回転時は、シートを前上がりチルト姿勢に作動し、かつその状態にロックして車両に干渉することがなくシートが車両前向きから横向き及び車両横向きから前向きへ回転できる装置を提供できる。 In the vehicle seat device of the present invention, a footrest is set at a position lower than the door opening to ensure a good standard riding posture, and when rotating, the seat is operated in a forward tilting posture and in that state. It is possible to provide a device that can rotate the seat from the front side to the side of the vehicle and from the side to the front side of the vehicle without interfering with the vehicle by locking the door.

It brings the convenience of being able to do it.

本発明の車両用シート装置は、シートが車内格納位置では、標準チルト姿勢に作動しないと格納できないので、標準チルト姿勢への変換が強制され、安全な走行乗車姿勢が維持される。 In the vehicle seat device of the present invention, since the seat cannot be stored in the vehicle interior storage position unless it is operated in the standard tilt posture, the conversion to the standard tilt posture is forced and the safe traveling riding posture is maintained.

本発明の車両用シート装置は、シートを車両前向きから横向きへの回転では、解除レバーを操作すると格納位置ロックを解除すると同時にチルトロックも解除するから、容易な操作でロックを解除することができ、また、容易にシートを横向き方向に回転させることができ、僅かに回転させたところで解除レバーを開放すると、その状態でチルトロックがなされてチルト姿勢を維持し、回転ロック手段は次に到達するロック孔と自動的に係合して回転を停止する。 In the vehicle seat device of the present invention, when the seat is rotated from the front to the side of the vehicle, when the release lever is operated, the storage position lock is released and at the same time the tilt lock is released. Therefore, the lock can be released by an easy operation. In addition, the seat can be easily rotated in the lateral direction, and when the release lever is released when the seat is slightly rotated, the tilt lock is performed in that state to maintain the tilt posture, and the rotation lock means reaches the next. Automatically engages with the lock hole to stop rotation.

本発明の車両用シート装置の回転ロック手段は、シートの位置により作動し、回転規制手段はシートの姿勢により作動するので、次の姿勢の姿勢にチルト作動をしないと規制作動を持続するので、姿勢が強制され、誤作動が確実に改善される。 The rotation locking means of the vehicle seat device of the present invention operates according to the position of the seat, and the rotation regulating means operates according to the posture of the seat. Posture is forced and malfunctions are definitely improved.

本発明の車両用シート装置は、シートを車両横向きから前向きへの回転では、解除レバーを操作して回転ロック手段の横向位置ロックと標準チルト姿勢又は更に前下がりチルト姿勢の姿勢ロック手段を解除し、シートを前上がりチルト姿勢にチルト作動し、その前上がりチルト姿勢で回転規制手段の内側作動規制プレートの前側衝突部と衝突を解除して回転が可能となり、解除レバーを操作して前向き回転を行うことによってチルトロックが掛り、確実にシートを前上がりチルト姿勢にロックした状態で車内へ前向き回転が行え、解除レバーを開放して回転ロック手段を待機状態に保持し、姿勢ロック手段を前上がりチルト姿勢にロックとして前向き回転が行なえるものである。 In the vehicle seat device of the present invention, when the seat is rotated from the vehicle sideways to the forward direction, the release lever is operated to release the lateral position lock of the rotation locking means and the posture locking means of the standard tilt posture or the forward downward tilt posture. , The seat is tilted to the forward tilt posture, and in the forward tilt posture, the collision with the front collision part of the inner operation regulation plate of the rotation regulating means is released and the rotation becomes possible, and the release lever is operated to rotate forward. By doing so, the tilt lock is applied, the seat can be reliably rotated forward in the tilted posture, the release lever is released to hold the rotation locking means in the standby state, and the posture locking means is raised forward. It can be rotated forward as a lock in the tilted posture.

本発明の車両用シート装置は、シートを前上がりチルト姿勢の状態で車内へ前向き回転では、解除レバーを開放して回転ロック手段を回転ロック待機状態で回転するから、回転ロック手段が回転中途位置ロックが作動し、かつ回転規制手段の標準チルト復帰用衝突部に衝突して回転を停止する。そして解除レバーを操作して回転ロック手段の回転中途位置ロックを解除し、前上がりチルト姿勢の姿勢ロック手段を解除し、解除レバーを操作したままシートを前上がりチルト姿勢から標準チルト姿勢にチルト作動して回転規制手段の標準チルト復帰用衝突部を解除し、シートを標準チルト姿勢の状態で格納位置へ回転させて解除レバーを開放して回転ロック手段を回転ロック待機状態として前向き回転を格納位置まで行えば格納位置でシートの回転ロック手段は格納位置にロックし、チルトロック手段は標準チルト姿勢にロックする。 In the vehicle seat device of the present invention, when the seat is rotated forward in the vehicle in the forward tilted posture, the release lever is released and the rotation lock means is rotated in the rotation lock standby state. Therefore, the rotation lock means is in the intermediate rotation position. The lock is activated and the rotation is stopped by colliding with the standard tilt return collision portion of the rotation regulating means. Then, the release lever is operated to release the mid-rotation position lock of the rotation lock means, the attitude lock means of the forward upward tilt posture is released, and the seat is tilted from the forward upward tilt posture to the standard tilt posture while the release lever is operated. Then, the collision part for standard tilt return of the rotation regulating means is released, the seat is rotated to the storage position in the standard tilt posture, the release lever is released, the rotation lock means is set to the rotation lock standby state, and the forward rotation is stored. At the retracted position, the seat rotation locking means locks to the retracted position, and the tilt locking means locks to the standard tilt posture.

本発明の車両用シート装置における回転規制手段を構成する内側作動規制ピンと外側作動規制ピンは、回転部材の回転中心からの伸びる同一放射線において内外に離隔して配備され、シート取付部材のチルト姿勢により昇降させて夫々対応する内側作動規制プレートと外側作動規制プレートに設けた衝突部に夫々対応させて衝突停止させるものであるから、一方方向の回転にのみ対応させることができ、チルト姿勢を変換することにより夫々規制を解除することができる回転規制手段を付設することができる。 The inner operation regulation pin and the outer operation regulation pin constituting the rotation regulation means in the vehicle seat device of the present invention are separately arranged inside and outside in the same radiation extending from the rotation center of the rotating member, and are arranged by the tilt posture of the seat mounting member. Since the collision is stopped by corresponding to the collision portion provided on the inner operation regulation plate and the outer operation regulation plate which are raised and lowered respectively, it is possible to correspond only to the rotation in one direction and the tilt posture is changed. As a result, it is possible to attach rotation regulation means that can release the regulation respectively.
