DETAILED DESCRIPTION

[0051] FIG. 1 shows a motor vehicle 1000 having a vehicle roof 100. In the present case, vehicle roof 100 is formed by a window module 10. Window module 10 is placed on top of a peripheral supporting receptacle 101 of a body frame 102 of a vehicle body 103, in particular foamed around and/or glued to and/or injection-molded to said body frame 102 as a structural unit, for example via its edge portion 106. In the present case, window module 10 can also be comprised by a roof module 11 which is configured to support semi-autonomous or autonomous driving using motor vehicle 1000. Window module 10 or roof module 11 covers a roof opening 105 from a vehicle environment, such that rain is prevented from entering, for example. Window module 10 is configured as a fixed transparent window module, which is also referred to as fixed transparent module, FTM for short. Window module 10 or roof module 11 at least partially forms a roof skin 12 of vehicle roof 100, which functions as an outer sealing surface.

[0052] Window module 10 comprises at least one at least partially transparent window 14, which forms a fixed panoramic roof in the present case. Window 14 has an outer surface facing a vehicle environment and an inner surface opposite the outer surface and facing a vehicle interior. In an exemplary manner, at least one environment sensor 16 is disposed on the outer surface in the present case, said environment sensor 16 being configured to send and/or receive electromagnetic signals in order to detect a vehicle environment. Environment sensor 16 is comprised in a sensor housing 18, which has a see-through portion 19 though which environment sensor 16 sees in order to detect the vehicle environment.

[0053] According to the invention, at least one plastic structure 20, which is at least configured as a burn protection for at least one vehicle occupant, is disposed on the inner surface of window 44. Plastic structure 20 has a lower thermal conductivity compared with the at least one window. Plastic structure 20 is glued to the inner surface of at least one window 14 (cf. FIGS. 5 and 6) and/or disposed on the inner surface, in particular connected to said inner surface, by foaming (cf. FIGS. 2 and 3) and/or overmolding.

[0054] Generally, plastic base body 22 can be dimensioned and/or formed in various ways. Preferably, plastic base body 22 is duct-shaped and/or rib-shaped, as can be seen in schematic view in FIG. 2, for example. The duct-shaped design, i.e., providing a cavity 24 within plastic base body 22 is schematically illustrated in FIG. 3. For example, plastic structure 20 can be formed honeycomb-like, as shown in FIG. 2, such that an ideal ergonomic protection against contact is provided.

[0055] Plastic base body 22 can preferably be glued to a frit 26 by means of a gluing agent, said frit 26 being formed on window 14. The gluing agent preferably forms an adhesive layer 28 between frit 26 and plastic base body 22, as can be seen in FIGS. 5 and 6. Preferably, a foam layer 30 and/or a textile layer 32 can also be applied to or on plastic base body 22 (cf. FIGS. 5 and 6), in particular glued to said plastic base body 22. Each additional layer is preferably laminated on plastic base body 22 via an adhesive layer, which can be applied in particular by means of a spray glue. Through this, in particular through an additional foam layer 30, plastic base body 22 can also function as impact protection. In terms of a color, structure, pattern and/or functional effect of the plastic base body, it is generally also possible to provide at least one film, which is preferably introduced into plastic base body 22 by an in-mold lamination process (not shown).

[0056] It can also be preferred if at least one light-emitting element and/or antenna element and/or a measuring sensor and/or a communication device is/are disposed in, in particular enclosed by, a foam and/or overmold between at least one window 14 and at least one plastic structure 20. Particularly preferably, plastic structure 20 comprises at least one light-emitting element and/or antenna element and/or a measuring sensor and/or a communication device of this kind (see FIG. 6). FIG. 6 shows a light-emitting element 34 in an exemplary manner. Light-emitting element 34 can be an LED circle, for example. Light-emitting element 34 can send electromagnetic radiation in the form of, in particular, visible light, into an environment through a glazing 36 provided on plastic structure 20, for example.

[0057] In an alternative or additional embodiment, it can also be preferred if plastic base body 22 is disposed on the inner surface of window 44 via an installation component 38. Illustrative examples of this kind are shown in FIGS. 7 to 17 and are described in more detail below. In an arrangement of this kind, plastic base body 22 is disposed at a distance to the inner surface of window 44 because of the interposition of the installation component in the installed state (see FIGS. 11, 16 and 17).

[0058] Installation component 38 is glued to (see for example adhesive layer 39 in FIG. 15) the inner surface of the at least one window 14 and/or screwed to and/or disposed on, in particular connected to, the inner surface by foaming and/or overmolding. Installation component 38 is configured to receive plastic base body 22 at least partially, in particular captively (see FIGS. 10, 11 and 15 to 17). Plastic base body 22 can also be connected to installation component 38 via a screwed connection 40, as can be seen in FIG. 16. Plastic base body 22 is preferably housed in installation component 38 such that it is pivotable around a pivot axis 42, preferably at least on one side, in order to facilitate its installation. For example, plastic base body 22, which is formed in particular grid-like according to FIGS. 7 to 17, can be connected to installation component 38 via a respective free end or installation end portion 44. For example, a hinged connection is possible, in which a socket is formed on installation component 38, and installation end portion 44 has a hinge portion complementary thereto. Preferably, several end portions of plastic base body 22 can be connected to the inner surface of window 44 via one installation component 38 each. Plastic base body 22 is in particular captively connected to the at least one installation component 38, preferably via a clip connection or a hinged connection and/or screwed connection 40.

[0059] Installation component 38 can also form an in particular sleeve-like bearing position 46 to which plastic base body 22 is connected (see FIG. 17). This allows a simple push-fit connection between plastic base body 22 and installation component 38. Furthermore, only bearing position 46 must be disposed on the inner surface of window 44. For example, bearing position 46 is over-molded by a plastic material, in particular polyurethane. Overmold 48 also connects bearing position 46 to the inner surface of window 44.
