Window regulator having a driving threaded shaft whose distance from the window is variable

摘要

A window regulator includes 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 up and down along the shaft, a driving member ( 26 ) fastened to a lower zone of the window ( 16 ), and a member 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 member includes at least a rigid connecting rod ( 36; 36 a) articulated on one side to the nut screw ( 24 ) and on the other side to the driving member ( 26 ), which is able to assume different tilts when the distance between the driving member ( 26 ) and the nut screw ( 24 ) changes.
