Description

The invention relates to a vehicle window having the features of the preamble of claim 1. Such a vehicle windscreen is made from the printed text WO 2021/198262 A1 The vehicle windscreen is known and designed as a fixed roof element or as a cover element of a roof opening system, by means of which a roof opening can be selectively closed or opened. The windscreen comprises a windscreen assembly with a composite structure and includes a light guide layer, which forms the inner surface of the windscreen assembly. Strip-shaped light coupling elements are attached to this layer and are arranged at opposite edges of the windscreen assembly. The light coupling elements are part of a lighting device that includes light sources whose light can be coupled into the light guide layer of the windscreen assembly by means of the light coupling elements. The coupled light can then be emitted from the light guide layer towards the vehicle interior by means of corresponding output coupling elements. As already described, the coupling of light into the light guide layer occurs at opposite edges of the windscreen assembly. This requires a multitude of light sources, which are also arranged along the respective edges of the windscreen assembly. Furthermore, it is necessary to wire the light sources arranged on both sides, which involves both manufacturing effort and corresponding material and cost expenditure. The invention is based on the objective of creating a vehicle windscreen of the type mentioned in the introduction, which offers extended lighting possibilities compared to the prior art mentioned above. This problem is solved according to the invention by the vehicle window with the features of claim 1. According to the invention, a vehicle windshield is proposed comprising a windshield assembly and a lighting device with a light source. The windshield assembly has an outer surface facing the vehicle environment and an inner surface facing the vehicle interior, and a circumferential rim comprising two transverse legs and two longitudinal legs connecting the two transverse legs. A transverse web is arranged on the inner surface of the windshield assembly, i.e., on the large surface of the windshield assembly facing the vehicle interior. This web connects the two transverse legs and/or the two longitudinal legs and at least partially accommodates the lighting device. According to the invention, an additional functional element, in the form of a crossbar, is attached to the inside of the windshield assembly of the vehicle windshield. This element serves a lighting purpose, specifically for the direct illumination of certain areas of the vehicle interior and/or for the generation of light patterns or the like on the windshield, i.e., as ambient lighting of the windshield. The crossbar, which extends across the viewing area of the windshield, is designed in particular as a strip that rests against the inside of the windshield assembly. The crossbar also allows for the integration of design elements on the underside of the windshield. In principle, the glass pane assembly of the vehicle window according to the invention can have a laminated structure and be designed as so-called laminated safety glass (VSG). However, it is also conceivable that the glass pane assembly is designed as a single pane or tempered safety glass (ESG). When using a composite structure as a disk body arrangement, this preferably comprises an outer disk body and an inner disk body, which is connected to the outer disk body via at least one bonding layer. The inner disk body can then form a light guide layer into which, for example, light from the light source of the lighting device can be coupled. An additional, potentially costly, light guide layer is not required. When the lighting device is activated, the inner disk body, and the corresponding coupling of the coupled light, can provide a planar and/or patterned ambient light function. In order to integrate the lighting device into the crossbar of the vehicle windshield according to the invention in a convenient manner, the crossbar in a specific embodiment has a molded section that is formed or bonded to the inside of the windshield assembly. This molded section forms a base for the crossbar, enabling the mounting of the lighting device elements and, if necessary, the integration of other functionalities onto the crossbar. When the crossbar is formed onto the inside of the windshield assembly, the connection between the windshield assembly and the crossbar is established. The crossbar and the cross member are integrated into the molding process. The molded section of the cross member is then directly attached to the inside of the disc assembly in a mold, meaning it is connected to the disc assembly after a foaming or injection molding process. In the case of a prefabricated cross member, it can be fixed or held to the inside of the disc assembly using an adhesive, adhesive tape, or other fixing agen
