An operating mechanism, particularly for the windows of motor vehicles, includes a flexible threaded cable which is mounted in a tubular portion formed by two housing parts which are interconnected. The cable is engaged by a driving gear which is driven from a pinion gear which is affixed to a shaft for rotation therewith. The shaft is driven through a spline gear, for example, by a manually operated crank handle or by a driving motor. The pinion gear also meshes with a gear formed on the exterior of a spring pulley. The spring pulley houses at its interior a coil spring which is tensioned or wound during the driving of the motor to move the window operating cable in an opening direction. During the driving of the cable in an opposite closing direction the spring therefore unwinds and aids in the driving operation. |
