Description

Technical Field

[0001] The invention relates to a roof arrangement for a motor vehicle having the features of the preamble of claim 1 . Background Art

[0002] Such roof arrangements are known today, for example fixed roofs which are configured as panoramic sunroofs and are provided with a transparent glass or plastic panel through which ambient light can enter the interior of the respective motor vehicle. Vehicles with fixed transparent modules (FTM) are also known.

[0003] In order to reduce the heat input into such transparent roof elements due to solar radiation, known vehicles usually have a roller blind system with a movable sunshade, which can be used to at least temporarily cover the transparent roof element from the inside.

[0004] For example, the glass or plastic panel has a circumferential edge foaming, which is made in particular of a polyurethane material and can be used to seal adjacent outer skin parts. In addition, the known roof arrangement comprises a top lining with a lining element, which forms the inner visible surface of the roof arrangement visible from the interior of the vehicle. In order to give the interior of the roof arrangement an aesthetic appearance, the edge of the lining element is adjacent to the glass or plastic panel. Its fastening is achieved by means of clips that interlock with docking elements adhered to the glass or plastic panel. Special components are required for this, which is reflected in the cost of the roof arrangement. In the prior art, the clips are usually fastened to frame parts and / or guide rails and / or steel or plastic frame elements and / or profile strips of the roller blind system and / or the vehicle body.

[0005] For example, a roof arrangement comprising a roof panel with edge foaming is known from DE 101 55 170 B4.

[0006] Known roller blind systems are increasingly used less and less in modern vehicle construction. The use of electronically switchable glass, the transmittance of which can be adjusted by means of electrically activated control signals, and / or the use of glass with low solar transmittance, is making conventional roller blind systems increasingly obsolete. Furthermore, new technologies mean that several components that previously belonged to roller blind systems can now be dispensed with. This allows the vehicle interior design to be simplified and the usable interior space to be increased.

[0007] This has the disadvantage that there are no longer any frame parts and / or guide rails and / or steel or plastic frame elements and / or profile strips available for fixing the lining elements of the roof lining, for example for fastening fastening clips or the like. Summary of the invention

[0008] It is an object of the present invention to further develop the roof arrangement in such a way that the above-mentioned problems are at least partially solved, in particular the fastening of the lining element to the fixed roof element is simplified.

[0009] This object is achieved according to the invention by a roof arrangement having the features of claim 1 .

[0026] For example, the fixed roof element is glued to the roof substructure by means of glue beads. If there is a space between the edge foaming and the molding, the glue beads are preferably arranged in said space. On the inside of the roof arrangement, this area is aligned with the headlining and is therefore not visible from the vehicle interior.

[0027] Preferably, the invention relates to a motor vehicle having at least one roof arrangement according to the invention. The motor vehicle can be a passenger car and / or a truck and / or a commercial vehicle and / or an autonomously or at least partially autonomously driven vehicle and / or a transport vehicle.

[0028] Obviously, the above-mentioned embodiments and illustrative examples and the embodiments not yet explained below can not only be formed separately, but also can form any combination without departing from the scope of the present invention. In addition, the above-mentioned elements are still to be discussed below. The embodiments and examples are equivalent or at least similar to all designs of the present invention, without separate mention. BRIEF DESCRIPTION OF THE DRAWINGS
