ABSTRACT:
Device for actuating at least one helically threaded, incompressible drive cable, which is axially movable, having a drive pinion seated on a drive shaft, and a cable guideway for guiding the drive cable in the area of the drive pinion. For the purpose of noise reduction, boundary edges of the cable guideway contacting the drive cable are of a configuration such that they form an angle with the longitudinal axis of the drive cable which deviates from 90 degrees; whereby an acute approach angle enclosed between the boundary edges of the cable guideway and the sections of the turns of the helical thread facing them, is larger than an acute elevation angle which is enclosed between the helical turns and a vertical plane which extends perpendicular to the longitudinal axis of the drive cable.
