Furthermore, the invention relates to a power window system, a motor vehicle door and a motor vehicle with such a fastening device.

In particular, in vehicles in which a window pane in a frameless door from a raised, closed position, in a lowered, open position can be transferred, it is necessary to precisely adjust the bias voltage with which the window pane in the closed state against the seals. For example, by changing the orientation of the guide rails of a window lift, tilting or pivoting of the window pane about the vehicle longitudinal axis can be effected in order to set with which bias the window pane rests against the seals in the closed state. Often, however, the space within a vehicle door or within the body is not sufficient to achieve a sufficiently large adjustment for adjusting the angle of the window by changing the position of the guide rails.

Out DE 28 43 633 C2 is a holder with guide jaws for a side window known within a body cavity of a

Motor vehicle is guided by means of at least one guide rail height adjustable and adjustable. At least on the side facing the viewing window, this holder has a curved surface on which a bearing shell forming an intermediate layer toward the viewing window rests. In addition, it is provided that a fastening shell connecting the bearing shell with the mounting element is arranged or designed so that the viewing window can be pivoted in the released state together with the bearing shell. The curved surface forms a spherical cap. The viewing window has a bore through which a clamping screw passes. By means of a special elastic spacer, the space between the lens and the clamping screw is completely filled, so that the positioning of the lens relative to the holder by the clamping screw and the spacer is fixed.

This holder has the disadvantage that a precise adjustment of the bias or the angular orientation of the lens is almost impossible. In particular, a precise adjustment of the bias in an already installed within the body of a motor vehicle window regulator including at least prefixed window is possibly in the lowered, open, position of the window a coarse adjustment possible, by repeatedly lowering, raising and readjusting in several iteration steps to the desired bias must be worked on. A precise setting in the raised, closed window position is not possible with this holder, because on the one hand, the window should be pressed defined against the seals, while on the other hand at the same time the clamping screw is fixed.

Out DE 199 43 619 A1 a device for a window pane of a frameless vehicle door is known. In this device, a driver in a vertical guide rail is vertically adjustable. A window pane is connected to the driver. To adjust the bias voltage with which the window pane rests against the sealing rubber of the door opening of the vehicle, this is pivotable in the transverse plane of the vehicle. For this purpose, the lower edge of the window pane with a vertical bolt passing through the adjusting bolt coupled, the coupling end is formed eccentrically to the axis of rotation of the adjusting bolt and adjusts the window pane during rotation of the adjusting bolt in the transverse direction. It is provided that the adjusting bolt is actuated by an opening in the door underside.

This adjustment device also has the disadvantage that an adjustment in the raised, d. H. closed window position is not possible. Rather, a setting of the bias can only be done in the lowered lower position, because the adjusting bolt and its lock nut can be reached with the necessary tools only in the lowered position. In particular, there is sufficient action space for the necessary to set wrench only in the lowered position. This has the consequence that the setting in several consecutive iteration steps, in which the window pane is raised and lowered, has to be done. This is until the correct preload is present in the closed position. In addition, in this adjustment no sufficient for all conceivable boundary conditions holding the disc, which is clamped only in a U-profile given.

The driver consists essentially of a base body and a receiving body, wherein the Main body is guided on the guide rail of the window and the window pane is clamped to the receiving body. The receiving body has two segments, each with a curved contact zone, which are associated with associated curved contact areas on the base body. To change the position of the receiving body to the base body, inter alia, a spindle is provided, which converts a rotary movement into a translational movement of the receiving body along the contact areas. In the mounting position of the driver, the spindle in the vehicle interior door is aligned substantially horizontally and arranged such that the position of the window can be adjusted only from the inside of the door. In particular, it is necessary that in order to adjust the disc position, either the door inner panel must be removed or a special access opening must be provided in the inner panel of the door to operate the spindle. This sometimes requires a significant, additional work or expense.

It is the object of the present invention to improve a fastening device, a power window system, a motor vehicle door and a motor vehicle of the type mentioned in that a reliable, precise and in particular quickly feasible adjustment of the bias and angular position of the window is possible.

In particular, it can alternatively or additionally be provided that the displacement device and the clamping mechanism are separate mechanical systems.

The abovementioned embodiments have the very particular advantage that an angular position and / or pretensioning set with the adjustment means also remains set when subsequently the window pane and / or the pane holder are finally determined.

In a particular embodiment, the angular orientation and / or the bias voltage is infinitely adjustable. This allows a particularly adapted adjustment of the bias and / or angular orientation of the window. It has been shown that in practice it is usually completely sufficient if the disk holder is mounted so as to be displaceable exclusively along a single guide track relative to the main body. Such an embodiment can be made mechanically robust and reliable and thus without any special effort. Such an embodiment can be achieved, for example, in that the curved surface is designed as a cylindrical section and / or the curved surface is designed as a cylindrical section whose cross-section is smaller than a semicircle.

Alternatively or additionally, at least one guide means may be present, which allows a displacement of the disc holder exclusively along a single guideway.

Alternatively to the aforementioned embodiments, it could be provided that the curved surface is formed as a section of a spherical surface, so that, for example, in addition to a pivoting about a vehicle longitudinal axis also a pivotability about a vehicle vertical axis is possible.

A power window system with a - motor-driven or manually operated - window lift, with which a window is selectively transferred to a raised, closed position or a lowered open position, and that is equipped with a fastening device according to the invention, has the particular advantage that the window can be mounted particularly precise and reliable at least in terms of bias. In particular, it is possible to carry out the fastening device according to the invention such that a setting of the bias in the raised, closed window position can be done. An elaborate setting in which the window pane has to be raised and lowered several times in an iteration process is thereby advantageously avoided.

In particular, it may be advantageously provided that the base body is slidably fixed to a guide rail of the window and / or that the window pane is pivotable by actuation of the adjusting means about an axis perpendicular to the guide rail and the window surface.
