Benefits of technology

[0008]A primary object of the present invention is to devise a production process for a motor vehicle roof cover with a glass pane in which the cover can be provided with electrical function elements as easily and reliably as possible. Furthermore, such a cover as will be created by means of the process of the invention.
[0010]In the approach in of the invention, it is advantageous that, because the electrical function elements are already integrated in a combination film before application to the cover pane, the actual production of the cover is greatly simplified, since only one film need be applied instead of several separate layers, and the risk of dirt inclusions and / or lamination faults in the application of the electrical function elements to the pane can be distinctly reduced. This greatly reduces production costs. Furthermore, combinations of different function elements on the cover can also be more easily implemented. By integration of the electrical function elements in the combination film, the difficulty of exact positioning of otherwise separate films in the application to the cover pane is eliminated. Moreover, floating in the film sandwich during the lamination process can be prevented. Thus, much more complex design versions overall can be implemented.
[0011]It is also advantageous that, because the shatter prevention film itself already forms a part of the function elements or acts as a carrier of them, additional films can be saved, by which a cover with reduced thickness and thus reduced installation space requirement can be achieved.

Problems solved by technology

Thus, much more complex design versions overall can be implemented.

Embodiment Construction

[0018]FIG. 1 shows a glass cover 11 of a motor vehicle roof into which electrical function elements have been integrated in the conventional manner. To do this, a carrier film 16 provided with electrical function elements is laminated onto the bottom of a glass pane 14 by means of a hot-melt adhesive film 12. A shatter prevention film 20 is then laminated onto the carrier film 16 with the function elements by means of another hot-melt adhesive film 18 and is designed to protect the film 16 with the function elements and the pane 14 from environmental effects and scratching, and in case of a fracture of the pane 14, it is designed to prevent the shards from falling into the vehicle interior. This structure, although it contains only a few layers, is already relatively complex to process, and moreover, entails the risk of dirt and air inclusions upon successive application of different layers. When the different layers are laminated, it needs to be ensured especially that optically un...

Abstract

A cover (11) with a glass pane (14) for a motor vehicle roof, in which, first, a combination film (10) with a shatter prevention film and electrical function elements (22, 24, 26, 28, 30) integrated into the combination film. The combination film is securely attached to a side of the pane, e.g., the side facing the vehicle interior. Furthermore, the electrical function elements are provided at various points and comprise different types of electrical function elements having different functions, e.g., an electroluminescent element and at least one of solar cells, an LCD, an SPD and an EC area.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is a divisional of commonly owned, co-pending U.S. patent application Ser. No. 10 / 880,096, filed Jun. 30, 2004.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention relates to a process for producing a cover with a glass pane and electrical function elements.[0004]2. Description of Related Art[0005]Covers provided with electrical function elements for an opening in a motor vehicle roof or solid glass covers are known in various embodiments. For example, published European Patent Application EP 1 234 721 A2 discloses an adjustable cover which is provided with flat illumination elements. The illumination elements are, for example, electroluminescent (EL) films. The required layers (electrodes, EL layer, protective films, etc.) are applied in succession. If, in a transparent region of a motor vehicle roof, the intention is to control the transparency of the cover by applying a voltage, electrochrome (...
