    • The mechanism comprises a movable member having three axes converging in a center of the mechanism, i.e. two main axes guided each by a crank, and a driven axis on which any point follows a substantially circular path centered in the above center. This is due to an appropriate geometry. A driven member may be linked to the movable part about the driven axis, and to a parallelism rod which is in turn linked to one of the cranks. The driven member remains then parallel to itself when the mechanism is actuated, that is, when the one crank is rotated with respect to a carrier member. The driven member may be a cylindrical side window of a car.
    • 该机构包括具有会聚在机构的中心的三个轴的可动构件,即每个由曲柄引导的两个主轴,以及从动轴,其中任何点都围绕以上述中心为中心的大致圆形路径。 这是由于适当的几何形状。 被驱动构件可以围绕从动轴线连接到可动部分,并且可以连接到平行杆,该平行杆又连接到曲柄中的一个。 当机构被致动时,即当一个曲柄相对于承载构件旋转时,被驱动构件保持与其自身平行。 从动构件可以是汽车的圆柱形侧窗。
