Window regulator for motor vehicles

摘要

A window regulator comprises a threaded shaft (20) arranged at the concave side of the window (16) and extending in the direction of sliding of the same window, a nut screw (24) engaging the threaded shaft (20), which is movable according a to-and-fro movement along the shaft, a driving member (26) fastened to a lower zone of the window (16), and means for interconnecting the nut screw (24) and the driving member (26), adapted to ensure the interconnection of the driving member (26) and the nut screw (24) independently of their distance. The interconnection means comprise at least a rigid connecting rod (36; 36a) articulated on one side to the nut screw (24) and on the other side to the driving member (26), according to an arrangement such as to assume a variable configuration when the distance between the driving member (26) and the nut screw (24) changes.
