Abstract:
A Bowden tube window regulator, adapted to receive a pair of Bowden tubes, and having a cable with a closed cable loop, which is to be guided over at least two guide pieces mounted along a displacement path of a window pane and is wound up on a cable drum coupled to a drive unit, wherein a cable section of the cable guided between the guide pieces is adapted to support an entrainment member associated with the window pane, the regulator comprising:a spring-loaded cable length compensating device, the device having a base member comprising a pair of cable sleeves, each of which being adapted to support a load from an end of a respective one of the pair of Bowden tubes;a locking element associated with both cable sleeves and coupled to the base member; andthe locking element being biased to move in a direction to compensate for cable slack when both cable sleeves are substantially unloaded by the Bowden tubes and adapted to move at least one of the cable sleeves and its respective Bowden tube into engagement;wherein each cable sleeve is displaceable from a set position relative to the locking element to a displaced position relative to the locking element to compensate for cable slack when the locking element is moved in said direction and is prevented from resetting from the displaced position to the set position by the locking element, andwherein the locking element is biased to move in a direction to cause at least one of the cable sleeves to move from the set position to the displaced position only when both cable sleeves are substantially unloaded by the Bowden tubes.
