Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The invention and other advantageous embodiments and developments thereof will be described and explained in more detail below on the basis of the examples shown in the drawings. The features set out in the description and the drawings can be implemented either individually or together in any combination in accordance with the invention. In the drawings:

BRIEF DESCRIPTION OF THE DRAWINGS

[0022] FIG. 1 is a schematic side view of a vehicle window,

[0023] FIG. 2 is a schematic side view of the vehicle window according to FIG. 1, and

[0024] FIG. 3 is a perspective view of an alternative embodiment of the vehicle window from FIG. 1.

DETAILED DESCRIPTION OF THE INVENTION

[0025] FIG. 1 shows a vehicle window 11. This vehicle window 11 comprises a glass body 12, which has an inside 14 and an outside 15. Said glass body 12 is delimited by an externally peripheral edge 16. The glass body 12 has a planar extent 18. This planar extent 18 is in a two-dimensional plane or is spherically curved. The glass body 12 further comprises a three-dimensionally deformed functional region 21. This three-dimensionally deformed functional region 21 is connected to the glass body 12 in one piece, or they consist of the same material. The glass in this case is a pressed glass, for example soda-lime glass, an aluminium silicate glass or a borosilicate glass. The three-dimensionally shaped functional region 21 is multiple times smaller than the planar extent 18 of the main body 12. In the embodiment example according to FIGS. 1 and 2, the three-dimensionally shaped functional region 21 bulges with respect to an inside 14 of the glass body. Alternatively, it can also be formed to bulge with respect to an outside 15 of the glass body 12. Advantageously, said three-dimensionally shaped functional region 21 is formed so as to adjoin the outer edge 16 by an edge portion 23. Said three-dimensionally shaped functional region 21 has a transition region 25 to the planar extent 18 of the main body 12. Said transition region is formed to be smooth. Preferably, the wall thickness of the glass body 12 is identical in the planar extent 18 of the glass body, in the transition region 25 and in the three-dimensionally shaped functional region 21.

[0026] The vehicle window 11 according to FIGS. 1 and 2 is specifically formed as a so-called triangular window, which is preferably installed so as to adjoin a C-pillar of a vehicle. It is a vehicle window 11 installed in a stationary manner in relation to the bodywork. A vehicle door can be provided opposite the three-dimensional functional region 21 or adjoining the edge portion 23, a frame preferably being provided on the vehicle door, which frame extends along the edge portion 23 of the functional region 31 and has an opening mechanism pointing towards the inside of the bodywork. As a result of the three-dimensionally shaped functional region 21, a recessed handle is thus formed, which makes it possible to actuate a locking mechanism arranged in a concealed manner in the side door.

[0027] FIG. 3 shows another alternative embodiment of a vehicle window 11. This vehicle window 11 can be a rear window or a tailgate, formed from the glass body 12 and the three-dimensionally shaped functional region 21. Said three-dimensionally shaped functional region 21 is formed as a spoiler. Advantageously, this three-dimensionally shaped functional region 21 can extend along two opposite edge portions 27, 28.

[0028] In addition, individual regions of the vehicle window 11, in particular regions that extend along the external peripheral edge 16 and/or also at least in part inside the three-dimensionally shaped functional region 21, preferably have a colouring. For example, regions of the vehicle window 11 can be provided with a black colouring.

[0029] In addition, at least one insert 31 can preferably be provided in the vehicle window 11, which insert is enclosed and retained by the glass body 12 at least in part. In the vehicle window 11 according to FIG. 3, the insert 31 can, for example, represent a component of a hinge for a tailgate.

[0030] The vehicle window 11 according to the above-described embodiments can comprise an overmoulding of a plastics material that extends at least in part along the peripheral edge 16 of the vehicle window 11. This overmoulding is formed as a seal for sealing an opening in a bodywork of a vehicle with respect to the vehicle window 11.

[0031] The embodiments of the vehicle windows 11 described above by way of example are preferably produced by a pressed-glass process. Said vehicle window 11 is thus produced from pressed glass by way of primary shaping. As a result, any designs for shaping the three-dimensionally shaped functional region 21 can be introduced into a planar extent 18 of the glass body 12. Said at least one functional region 21 can also be provided within a planar extent 18 of the glass body 12 at a distance from the peripheral edge 16. One or more three-dimensionally shaped functional regions 21 can be provided in the vehicle window 11.
