    • A reclining angle adjustment device for a seat includes a shaft having a concentric portion and an eccentric portion and rotatable for adjusting the reclining angle of the seat, a tapered bushing having a tapered inner peripheral surface engaging the eccentric portion along the shaft, a gear train including an external gear and an internal gear meshing with the internal gear, the internal gear having more teeth than the external gear, a first arm having one of the external and internal gears which is rotatably fitted at its center over the concentric portion, and a second arm having the other gear which is rotatably fitted at its center over the tapered bushing. A resilient member normally presses the tapered bushing axially of the shaft in a direction to strengthen meshing engagement between the external and internal gears.
    • 一种用于座椅的倾斜角度调节装置包括具有同心部分和偏心部分并可转动以调节座椅倾斜角度的轴,具有沿着轴接合偏心部分的锥形内周面的锥形衬套,齿轮系 包括外齿轮和与所述内齿轮啮合的内齿轮,所述内齿轮具有比所述外齿轮更多的齿;第一臂,其具有可旋转地装配在所述同心部分上方的外齿轮和内齿轮中的一个, 第二臂具有可旋转地装配在其中心的锥形衬套上的另一个齿轮。 弹性构件通常沿着轴的轴向按压锥形衬套,以加强外齿轮与内齿轮之间的啮合。

    • A reclining angle adjustment device for a seat includes a shaft having a concentric portion and an eccentric portion and rotatable for adjusting the reclining angle of the seat, the eccentric portion comprising an axially movable tapered ring, a gear train including an external gear and an internal gear meshing with the internal gear, the internal gear having more teeth than the external gear, a first arm having one of the external and internal gears which is rotatably fitted at its center over the concentric portion, and a second arm having the other of the external and internal gears which is rotatably fitted at its center over the tapered ring. A resilient member engages the tapered ring for normally pressing the tapered ring axially along the shaft in a direction to strengthen meshing engagement between the external and internal gears.
    • 一种用于座椅的倾斜角调节装置包括具有同心部分和偏心部分的轴,并且可旋转以调节座椅的倾斜角度,偏心部分包括可轴向移动的锥形环,包括外齿轮和内部齿轮的齿轮系 齿轮与内齿轮啮合,内齿轮具有比外齿轮更多的齿;第一臂,其具有可旋转地装配在其同心部分上方的外齿轮和内齿轮中的一个;以及第二臂, 外部和内部齿轮,其可旋转地安装在其中心在锥形环上。 弹性构件接合锥形环,用于沿着轴沿轴向轴向正常地挤压锥形环,以加强外齿轮与内齿轮之间的啮合。
