ABSTRACT:
An articulated window lifter, especially for motor vehicles, whose windowpane is to be not only lowered within predetermined boundaries but also has to be laterally displaced and pivoted for purposes of avoiding door frame parts and the like which lie in its way; a pinion supported on a base plate engages with a toothed sector which is pivotally supported on the base plate while linkage parts are pivotally connected with the toothed sector; two four-jointed transmissions with a common fixed pivot point on a base plate are thereby used in superposed relationship, whereby one of the four-jointed transmissions has a further pivot point on the base plate and includes two pivot arms pivotally supported in the two pivot points on the base plate and a rod connecting the two pivot arms with each other; the other four-jointed transmission includes a first pivot arm connected at a fixed angle, with a first one of the two pivot arms of the one four-jointed transmission; the first pivot arm of the other four-jointed transmission is thereby connected with a second pivot arm of the other four-jointed transmission by way of a connecting rod; the second pivot arm of the other four-jointed transmission is pivotally connected by way of a couple with the one pivot arm of the one four-jointed transmission; and the couple is also connected with the connecting rod of the one four-jointed transmission at a fixed angle whose apex lies along a toothed sector.
