Zusammenfassung:	A mechanism for pretensioning a cable, or like tension element, of a tension-element drive selectively engages the motor drives of the cable for pretensioning. The mechanism uses a sleeve on which a portion of the cable is wound, with another portion of the cable wound in an opposed direction on a drive shaft on the motor. A clutch connects the sleeve to the motor output shaft. An initiator mechanism selectively stops rotation of the sleeve and the cable portion wound on the sleeve while allowing the motor torque to act on the other end of the cable wound on the drive shaft.
