Abstract:
1. A window lift system, comprising: a pulling device including one upwardly pulling end and one downwardly pulling end; only a single catch for a window pane, the catch being moved up and down by the pulling device and being connected to the pulling device only by the one upwardly pulling end and the one downwardly pulling end, the catch having (i) a first fastening point connected to the upwardly pulling end of the pulling device and (ii) a second fastening point connected to the downwardly pulling end of the pulling device, the second fastening point being horizontally off-set from the first fastening point in the window pane plane such that, by means of the upwardly pulling end and the downwardly pulling end, torque is transferred to the window pane pressing the window pane against a guide edge independently of a direction of movement of the window pane when the window pane is fitted; and a positioning arrangement positioning and fixing the catch in respect of at least three degrees of freedom such that the catch is kept in a position defined in respect of said degrees of freedom even when the window pane is not fitted, wherein the positioning arrangement does not prevent the pulling device from transferring the torque to the window pane when the window pane is lifted.
