Abstract
A pretensioning mechanism for tension element drives includes a drive pinion including a pinion shaft and a pinion sleeve; a first tension element end anchor on the pinion shaft for securing one end of a tension element wound around the drive pinion in a first direction and a second tension element end anchor on the pinion sleeve for securing the end of another tension element wound around the drive pinion in a second, opposite direction; and a worm drive including a worm gear on one of the pinion sleeve and pinion shaft and a worm on the other of the pinion sleeve and pinion shaft for relatively counter-rotating said pinion shaft and pinion sleeve for simultaneously in a single action adjusting and fixing the pretension on the tension element.
