A motor-vehicle window lift comprises a mounting structure, a drive system, a cable system having two cable segments running substantially parallel to each other, reversing rollers for the cable system and two window-pane actuators each affixed to a respective one of the cable segments, the actuators are displaceably guided along a respective guide of the mounting structure, wherein the actuators are rigidly connected to each other by a rigid coupling such that the actuators are non-movably fixed to the rigid coupling in a lift operating condition.

Automatic length-correcting device for flexible cable drives in

The invention concerns a tensioning device for the cable of a cable window lifter which is mounted in a drive bracket pulled up and down along a guide rail by means of a cable wound around an actuation drum. One cable end is solidly joined to the drive bracket whereas the other cable end is connected by a directional lock to the drive bracket. This directional lock compensates any cable elongation taking place within the cable actuation system by means of spring action. The tensioning device of the invention is characterized by providing further compensating means. This further compensation is needed in the event of excessive stresses exerted on the cable actuation system in the closed window position which results in a spurious cable elongation caused thereby. It also eliminates this compensation when this excess stress is no longer present. These further compensation means may consist of a spring additionally inserted between the free cable end and the directional lock; however they may also consist of a tippable and displaceable molded part inside the directional lock. The spring compensates the spurious cable elongation by relaxing before the actual compensation spring becomes effective. In the embodiments with the additionally inserted molded part, the compensation of the spurious elongation takes place by tipping the molded part which slips further by one step (cog) in the directional lock and only upon a real cable elongation.

An apparatus to adjust the length of the sheath of a bowden cable and capable of transmitting substantial forces. The bowden cable sheath terminates into a sleeve with a stepped outside diameter whereby it can be inserted into a structure fixed housing against the force of a compression spring. The housing contains a set of spacer panes which are spring-loaded and rest on the large diameter of the sleeve and which upon displacement of the sleeve out of the housing sequentially drop on the small sleeve diameter. The dropped panes extend the sheath each time by their thickness and between the sleeve collar and the housing inside wall form the support for the force exerted on the bowden cable. In a special embodiment, the apparatus is equipped with mechanical means accessible from the outside which when actuated will reset the already dropped spacer panes into their initial positions. Another embodiment offers the possibility to reset the spacer panes into their initial positions by shaping the sleeve so asymmetrically that these spacer panes can be returned to their initial positions by a 90.degree. rotation of the sleeve and by displacing this sleeve into the end fitting and rotating back the sleeve. This embodiment is characterized by being close on all sides and denies access to water, dirt, etc.
