The present invention relates to a window-winding arrangement (1) as well as a motor vehicle door containing this window-winding arrangement. The window-winding arrangement contains a drive means (5) as well as a guide means for the drive and for guiding a pane (2) belonging to the window-winding arrangement. The drive means and guide means is designed in a manner such that the drive force for movement is applied onto the pane such that this (4.1; 4.2) independently of its movement direction is always pressed against a certain guide edge (6c) of the guide means. With this it is rendered possible on manufacture of the window-winding arrangement to envisage greater tolerances as well as to do away with the costintensive installation of additional guide rails in the door inner space. Furthermore one achieves a reduction in friction as well as a reduction in weight.
A window-winding arrangement (1), for a side pane (2) of a motor vehicle comprising a drive means (5) for applying a driving force to the pane to cause movement of the pane in two different directions, and a guide means for guiding the pane (2) during movement in either direction, the drive means configured to cause the pane to be pressed against the guide means during movement of the pane in either direction, and wherein the side pane is driven by a linear element associated with the drive means, the linear element having a first spring with a first spring force connected in series to the linear element, and a second spring with a second spring force connected in series to the linear element wherein the ratio between the spring forces is from about 1:1.5 to about 1:2.5, wherein the different spring forces are applied to two distinct locations on the pane to cause an edge of the pane to be biased toward the guide means;
A motor vehicle door containing a window-winding arrangement according to one of the preceding claims.
A motor vehicle comprising a pane and a window-winding arrangement associated with the pane, the window winding arrangement comprising a drive means (5) for applying a driving force to the pane to cause movement of the pane in two different directions, and a guide means for guiding the pane during movement in either direction, the drive means configured to cause the pane to be pressed against the guide means during movement of the pane in either direction, and wherein the pane is driven by a linear element associated with the drive means, the linear element having a first spring with a first spring force connected to the linear element, and a second spring with a second spring force connected in series to the linear element wherein the ratio between the spring forces is from about 1:1.5 to about 1:2.5 wherein the different spring forces are applied to two distinct locations on the pane to cause an edge of the pane to be biased toward the guide means;
A window-winding arrangement (1), for a side pane (2) of a motor vehicle comprising:
