Preferred developments are disclosed in the dependent claims.Further advantages of the invention are evident from the dependent claims, the description and the figures. Features described in connection with the component arrangement naturally also apply in connection with the sliding roof system according to the invention, the vehicle according to the invention and vice versa, so that with regard to the disclosure reference is or can always be made to the individual aspects of the invention in a mutually alternating manner.According to a first aspect of the present invention, there is provided a component assembly for a sunroof system of a vehicle. The component arrangement has a sliding roof section and a molded headliner section, wherein the sliding roof section has a latching section and the molded headliner section has a counter-latching section for a latching connection to the latching section. The mold headliner portion has a plastic carrier for elastic deformation of the counter-latching portion during a latching process with the latching portion.In the scope of extensive experimental experiments, it has been found that, using the elastically deformable plastic carrier for the counter-latching section, the latter can be brought into latching connection with the latching section in a surprisingly simple and nevertheless stable and long-lived manner. Compared to conventional component arrangements for a sliding roof system, the counter-latching section according to the invention is relatively light due to the use of the plastic carrier. A low weight is advantageous in particular when using the proposed component arrangement in a mobile system such as a vehicle. Corresponding advantages can also be achieved with regard to an associated production method for producing the plastic carrier.The counter-latching section according to the invention can also be implemented in a particularly space-saving manner by means of the plastic carrier. This allows improved head clearance for the user of the vehicle to be achieved.The plastic carrier is to be understood at least partially as a component of the counter-latching section. The sliding roof section is understood to mean a functional section of a sliding roof of the vehicle, which is installed in the vehicle in a non-destructively movable manner in a state mounted in the vehicle. The molded headliner portion is understood to mean a functional portion of a molded headliner of the vehicle which, in a vehicle-mounted state, is mounted with respect to the vehicle and / or with respect to a stationary component of the vehicle-such as the body-stationary or substantially stationary. The fact that the mold headliner and / or the mold headliner section are mounted in the vehicle in a stationary or substantially stationary manner is to be understood to mean that the mold headliner and / or the mold headliner section cannot be moved in a non-destructive manner in the vehicle as such. Only small partial sections of the molded headliner and / or of the molded headliner section such as the counter-latching section can undergo a slight movement due to their elastic deformability. The latching connection can also be understood to mean a snap connection.The plastic carrier can be designed as an essential component of the counter-latching section. That is, the plastic carrier can be predominantly responsible for the function, the weight and / or the dimension of the counter-latching section. The plastic carrier consists mainly of macromolecules. The plastic carrier preferably consists mainly of thermosetting plastic, i.e. it predominantly comprises thermosetting plastics.Particularly preferably, the plastic carrier consists of a non-fiber-reinforced plastic in the region of the molded headliner portion or molded headliner that participates in the elastic deformation of the counter-latching portion, i.e., likewise experiences a change in shape during the elastic deformation of the counter-latching portion. This facilitates the elastic deformation of the counter-latching section, since the forces required for this are reduced in comparison with the use of a fiber-reinforced plastic.In contrast, the plastic carrier in the region of the molded headliner that does not participate in the elastic deformation of the counter-latching section, i.e., does not experience any deformation during the elastic deformation of the counter-latching section, is preferably made of a fiber-reinforced plastic, in particular a GRP or CFRP, or preferably contains such a plastic. This increases the strength and dimensional stability of this region compared to the use of a non-fiber-reinforced plastic.According to a further embodiment of the present invention, it is possible that in a component arrangement the plastic carrier is at least partially part of the counter-latching section and the plastic carrier is surrounded at least in sections by a casing section in the region of the counter-latching section, wherein the casing section has a different material composition than the plastic carrier. This makes it possible to provide the surface of the counter-latching section with desired optical and / or functional properties in a simple and flexible manner. This is possible in particular on account of the space-saving and weight-saving construction of the plastic carrier, as a result of which a further cladding layer or the cladding section is compatible with the stringent requirement with respect to compactness and weight reduction in a mobile system. The jacket section can be configured, for example, as a decoration which surrounds the plastic carrier at least in the region of the counter-latching section.Furthermore, it is possible that in a component arrangement according to the present invention, the counter-latching section has a counter-latching tip which is of beak-shaped configuration in cross section. The beak shape has proven to be surprisingly advantageous. The beak shape can be used to realize both an advantageous sliding surface on an upper side of the beak shape and a desired holding surface on an underside of the beak shape, in particular in the region of a beak tip. A beak shape is to be understood in the present case in particular as a shape which tapers relatively sharply on a front side and which has an upper side which is curved towards the tip and an underside which is curved towards the tip. The upper side is configured above the lower side in a state in which the component arrangement is installed in the vehicle.A further advantage of the present invention can be made possible by a component arrangement in which the latching section has a sliding surface and the counter-latching section has a counter-sliding surface for in particular linear or substantially linear sliding contact with the sliding surface during a latching process between the latching section and the counter-latching section. In comparison with a planar sliding contact in which two sliding surfaces rub against one another in a planar manner, the inventive design of the counter-sliding surface makes it possible to keep the frictional resistance relatively low during a sliding operation and at the same time to ensure a relatively high component stability. The counter-sliding surface may for example comprise a curved, a kinked and / or a corrugated surface for establishing the linear or substantially linear sliding contact with the sliding surface. For this purpose, the sliding surface preferably has a straight or substantially straight surface. For linear sliding contact, the counter-sliding surface is preferably curved, in particular curved in the direction of the desired sliding movement.In a component arrangement according to the present invention, the latching section can have a latching tip which is V-shaped in cross section. The latching tip is understood to mean an end region of the latching section which, in cross section, tapers in a V-shaped manner to a point or substantially to a point. The V-shape makes it possible to provide a desired sliding surface in a material-saving manner and thus in a weight-saving manner. The latching tip V-shaped in cross section can therefore have a first outer surface section as sliding surface for the counter-sliding surface and a second outer surface section as bearing surface and / or latching surface for the counter-latching section.In addition, it is possible in a component arrangement according to the invention for the latching section to have a recess with a bearing surface for bearing a counter-latching tip of the counter-latching section, and a stop which, in a state of the component arrangement installed in the vehicle, is configured above the recess in the direction of gravity, wherein the counter-latching section has a counter-stop for establishing a positioning contact between the stop and the counter-stop. By the cooperation of the stop and the counter-stop, the counter-latching section can be held stably on the latching section with simple means. The stop can also serve as positioning means for positioning the counter-latching section in the desired position on the latching section. For this purpose, the stop can be configured in an opening direction of the recess at the level of an opening of the recess and / or at a distance from the opening.It is particularly advantageous if the stop in a component arrangement according to the invention is designed projection-like. As a result, the stop can be provided in a material-saving and correspondingly weight-saving manner. A length of the stop in the projection direction is preferably at least twice as long as a height of the stop.According to a further aspect of the present invention, a sliding roof system for a vehicle is provided, wherein the sliding roof system has a component arrangement according to one of the preceding claims. Thus, the sliding roof system according to the invention brings with it the same advantages as have been described with reference to the component arrangement according to the invention. The sliding roof system is preferably designed in the form of an electrically operable sliding roof system.Furthermore, a vehicle having a sliding roof system as described above is proposed. The sliding roof system according to the invention thus also brings with it the advantages described above. The vehicle can be designed as a road vehicle, aircraft, watercraft, rail vehicle and / or as a robot vehicle. The vehicle is preferably designed as a road vehicle, in particular in the form of a passenger car.The invention relates to a vehicle with a panoramic roof or sliding roof system, in which the molded headliner has a circumferential reinforcing frame on its side facing away from the vehicle interior. This reinforces an opening edge region of the molded headliner surrounding the roof window in order to increase the component rigidity of the molded headliner opening edge region.In a component arrangement known from the prior art, the reinforcing frame is connected to the molded headliner by means of a material bond, for example by adhesion. The reinforcing frame has a number of attachment points which can be fastened to a roof system mounted on the body roof structure.According to the invention, the molded headliner is therefore not directly fastened to the sliding roof system of the vehicle, but rather with the circumferential reinforcing frame being interposed, which frame is connected to the molded headliner in a materially integral manner and reinforces the molded headliner opening edge region which surrounds the roof window. The reinforcing frame therefore also takes over the connection to the roof system in dual function in addition to an increase in the rigidity of the molded headliner. In addition, at least one connection point between the molded headliner reinforcement frame and the roof system mounted on the vehicle body roof structure is realized as a latching connection. The latching connection according to the invention has a latching element which is formed in the same material and integrally on the molded headliner reinforcement frame and a roof system latching contour which interacts therewith. The reinforcing frame latching element is designed to be elastically flexible. When joining the molded headliner to the roof system installed on the vehicle body side, the reinforcing frame latching element is brought into latching engagement with the roof system latching profile under elastic deformation.It is preferred if the reinforcing frame has a pronounced inherent rigidity. Against this background, the reinforcing frame can be an angular profile in cross section, namely with a base section lying substantially in a horizontal plane in the installed position of the headliner. This transition edge merges on the inside of the vehicle into an edge web which is raised upwards in the vertical direction. Both the base section and the edge web of the reinforcing frame are connected to the mold headliner opening edge region in a materially bonded manner (i.e. by adhesion).In a technical implementation, the latching element protrudes with a lateral offset outwards from the reinforcing frame edge web. In addition, the latching element is spaced apart from the reinforcing frame base section by a clear height in order to ensure a simple joining operation. In the joining process, the latching element formed on the reinforcing frame edge web is elastically adjusted inwardly or outwardly of the vehicle at the transition edge, acting as a bending edge, between the reinforcing frame base section and the reinforcing frame edge web.The latching element realized with the above geometry interacts with a roof system latching profile described below, which can be designed to be extremely reduced in installation space compared to the prior art: the roof system latching profile is thus designed as a U profile which has a latching recess open toward the inside of the vehicle. The latching recess is bounded by a profile leg at the bottom of the vehicle and a profile leg at the top of the vehicle, which are connected to one another via a profile base.The roof system latching profile can be, for example, a component-rigid extruded aluminum part.In the joining process, the molded headliner is moved in a joining direction toward the vehicle right as far as into a latching connection with the roof system latching profile. With regard to an easy-running joining process, the vehicle-lower profile limb of the U-shaped latching profile has a run-on slope. During the joining process, the reinforcing element latching element is brought into contact with the run-on slope formed on the lower profile limb of the vehicle. The reinforcing frame latching element, which is in sliding contact with the run-on slope, is displaced into a release position during the further course of the joining process, with the build-up of an elastic restoring force. After overcoming the run-on slope, the reinforcing frame latching element is displaced into the latching recess of the U-shaped roof system latching profile, reducing the elastic restoring force, as a result of which the reinforcing frame latching element engages behind the vehicle-lower profile limb of the U-shaped roof system latching profile.To further simplify the joining process, it is preferred if the molded headliner reinforcement frame has a height stop. During the joining process, the height stop comes into contact with a roof system mating contour when the mold headliner installation position is reached. In a design variant reduced in installation space, the height stop can be formed by a vehicle-upper, free stop edge of the reinforcing frame edge web. It is preferred if the vehicle-upper, free stop edge is in contact with the roof system mating contour with a support base that is as large as possible. In view of this, a transverse stop flange may be formed on the stop edge of the reinforcing frame. The stop flange can protrude beyond the reinforcing frame edge web by an overdimension towards the inside of the vehicle and / or towards the outside of the vehicle.With a view to reducing the installation space requirement, it is preferred if the roof system mating contour, which in the installed position of the headliner is in abutment with the abutment edge of the reinforcing frame edge web, is realized as follows: Thus, the profiled limb of the U-shaped roof system latching profile on the top of the vehicle can be extended towards the inside of the vehicle with a protrusion compared to the profiled limb on the bottom of the vehicle. The protrusion of the vehicle-upper profile limb can form the roof system mating contour which, in the installed position of the headliner, interacts with the height stop of the reinforcing frame.The stop flange formed on the reinforcing frame edge web preferably extends without interruption around the roof window opening in order to achieve a contact as large as possible between the stop flange and the upper profile limb of the roof system latching profile. In contrast, the latching element does not extend continuously around the roof recess in the circumferential direction. Rather, a plurality of latching elements are provided, which are formed on the reinforcing frame edge web at a circumferential distance from one another.It is preferred if, in the installed position of the headliner, a clearance-free clamping of the reinforcing frame latching element is provided in the U-shaped roof system latching profile. Against this background, an upper side of the vehicle and a lower side of the latching element are formed by an elastically compressible material. In the undeformed state, the latching element has, between its side on the top of the vehicle and its side on the bottom of the vehicle, a latching element height which is dimensioned to be greater than a latching profile height between the two profile legs on the top of the vehicle and on the bottom of the vehicle. The latching process therefore takes place while reducing the material thickness of the elastically compressible material and while building up a restoring force in the elastically compressible material, wherein a play-free latching is ensured.In one technical implementation, the reinforcing frame can be a plastic part. Further functional components can be integrated on the plastic reinforcing frame in a materially uniform and / or one-piece manner, for example a cable fastener, a head impact deformation element, a luminaire holder, a luminaire frame and / or an ambient lighting.In the production of a molded headliner, a substantially planar, multilayer molded headliner semi-finished product is first provided, namely consisting of a solid core layer and a decorative layer on the visible side (for example made of foam material). Subsequently, in a press molding step, a mold forming is performed. For this purpose, the molded headliner semi-finished product is placed together with the reinforcing frame in a hot press. After the forming of the mold lining carried out in the hot press, further process steps, for example a laminating step and / or a mold trimming, are carried out.An exemplary embodiment of the invention is described below with reference to the attached figures.The following are shown: FIG. 1 shows a component arrangement not included in the invention in a first functional state, FIG. 2 shows a component arrangement not included in the invention in a second functional state, FIG. 3 shows a component arrangement not included in the invention in a third functional state, FIG. 4 shows a component arrangement not included in the invention in a fourth functional state, and FIG. 5 shows a vehicle with a sliding roof system according to the invention. FIG. 6 is a top view of a vehicle with a sliding roof system; FIGS. 7 and 8 are sectional views along the sectional planes A-A and B-B from FIG. 6 or from FIG. 9 ; FIG. 9 shows a reinforcing frame in isolation; and FIGS. 10 and 11 are views of a clip connection between longitudinal and transverse struts of the reinforcing frame, respectively.Elements with the same function and mode of operation are provided with the same reference numerals in each of the figures.FIG. 1 shows a component arrangement 10 for a sliding roof system 11 of a vehicle 12 also shown in FIG. 5, the component arrangement 10 having a sliding roof section 13 and a molded headliner section 14, wherein the sliding roof section 13 has a latching section 15 and the molded headliner section 14 has a counter-latching section 16 for a latching connection to the latching section 15. The mold headliner portion 14 includes a plastic carrier 17 for elastically deforming the mating latch portion 16 during a latching operation with the latch portion 15.The plastic carrier 17 is a component of the counter-latching section 16 and is surrounded by a jacket section 18 in the region of the counter-latching section 16. The jacket section 18 has a different material composition than the plastic carrier 17. In the example illustrated in FIG. 1, the jacket section 18 is partially designed in the form of a decoration for the molded headliner of the vehicle 12.As can be seen in FIG. 1, the counter-latching section 16 has a counter-latching tip 19 which is of beak-shaped configuration in cross section. The latching portion 15 has a sliding surface 20 and the counter-latching portion 16 has a counter-sliding surface 21 for linear or substantially linear sliding contact with the sliding surface 20 during a latching operation between the latching portion 15 and the counter-latching portion 16.According to the illustrated embodiment, the counter-slide surface 21 is curved on an upper side of the beak shape. The underside of the beak shape is likewise of curved configuration.The latching section 15 has a latching tip 22 which is V-shaped in cross section. The illustrated latching section 15 further comprises a recess 23 with a bearing surface 24 for supporting a counter-latching tip 19 of the counter-latching section 16, and a stop 25 which, in a state of the component arrangement 10 installed in the vehicle 12, is configured above the recess 23 or higher than the recess 23 in the direction of gravity. The counter-latching portion 16 has a counter-stopper 26 for making positioning contact between the stopper 25 and the counter-stopper 26. The stop 25 shown is designed projection-like. The stop 25 is thus designed as a positioning means for positioning the counter-latching section 16 in the desired position on the latching section 15. As shown in FIG. 1, the stopper 25 is positioned slightly apart from the opening, that is, more right than the opening, in an opening direction of the recess 23, that is, in a right direction in FIG. 1.With reference to FIGS. 1 to 4, the function of the component arrangement 10, i.e. a latching process between the sliding roof section 13 or the latching section 15 and the molded headliner section 14 or the counter-latching section 16, will be described below. As shown in FIG. 1, the sliding roof section 13 is first moved in the direction of gravity and in the direction of the molded headliner section 14 arranged in a stationary manner in the vehicle 12 until the sliding surface 20 of the sliding roof section 13 contacts the counter-sliding surface 21 of the molded headliner section 14. The moment of contact between the sunroof portion 13 and the headliner portion 14 is illustrated in FIG. 2. Subsequently, the sliding roof portion 13 is moved further in the direction of gravity, i.e. downward in the figures. In this case, the sliding surface 20 is pressed against the counter-sliding surface 21, as a result of which the molded headliner section 14 which is elastically deformable by the plastic carrier 17 is pressed onto the side, that is to say to the right in the figures. This is illustrated in FIG. 3. As soon as the sliding roof section 3 has been moved downward far enough, as shown in FIG. 4, the beak-shaped counter-latching tip 19 of the counter-latching section 16 snaps into the recess 23 of the latching section 15 and produces the desired latching connection. The counter-latching section 16 is now held on the latching section 15 by means of counter-stop 26 and counter-latching tip 19 between bearing surface 24 and stop 25.FIG. 5 shows a vehicle 12 with a sliding roof system 11 which has a component arrangement 10 as shown in FIGS. 1 to 4.An exemplary embodiment of the invention is described below with reference to FIGS. 6 to 11 : Thus, FIG. 6 shows a motor vehicle in whose vehicle roof 1 a sliding roof system 11 (FIG. 7 or 8 ) with an adjustable sliding roof window 5 is installed. The sliding roof window 5 covers a sliding roof recess 7 in FIG. 7, which is bounded in FIG. 7 by a circumferential opening edge region 9 of a molded headliner section 14. In FIG. 7, the molded headliner section 14 is constructed in two layers by way of example, namely with a component-rigid core layer 27 and a decorative layer 28 on the visible side (for example a fabric covering and / or a foam layer). On the side facing away from the vehicle interior, the molded headliner section 14 is glued to a circumferential reinforcing frame 40. The reinforcing frame 40 is made entirely of plastic material. By means of the reinforcing frame 40, the opening edge region 9 of the molded headliner portion 14 delimiting the sunroof recess 7 is reinforced in order to increase the component rigidity of the molded headliner portion 14.The reinforcing frame 40 has an angle profile in cross section shown in FIG. 7, namely with a base section 29 which, in the installed position in the form of a headliner, lies substantially in a horizontal plane. Both the base section 29 and the edge web 31 of the reinforcing frame 40 are connected to the molded headliner section 14 in a materially integral manner.According to the invention, the molded headliner section 14 can be brought via its reinforcing frame 40 substantially without tools into a locking connection with the roof system 11 installed on the vehicle body side. For this purpose, the molded headliner reinforcement frame 40 has a plurality of latching elements 32, which are integrally formed on the reinforcement frame 40 in a manner spaced apart from one another in a circumferential manner. Each of the latching elements 32 interacts with a U-shaped roof system latching profile 33 which is open toward the inside of the vehicle.The essence of the invention consists in a simple assembly of the molded headliner section 14 on the vehicle body-side roof system 11 from a manufacturing standpoint and in a space-saving realization of the attachment points required for this purpose between the molded headliner reinforcement frame 40 and the roof system 11.The geometry of one of the reinforcing frame latching elements 32 and of the U-shaped roof system latching profile 33 interacting therewith is described below with reference to FIG. 7: consequently, the latching element 32 projects with a lateral offset v outwards from the reinforcing frame edge web 31. The latching element 32 is also spaced apart from the reinforcing frame base section 29 over a clear height in order to ensure a perfect latching engagement with sufficient clearance with the roof system latching profile 33.The U-shaped latching profile 33 of the roof system 3 has a latching recess 41 which is open towards the inside of the vehicle. This is bounded in the vehicle vertical direction z by a profile leg 34 at the bottom of the vehicle and a profile leg 35 at the top of the vehicle, which are connected to one another via a profile base 36. In addition, the profile leg 34 at the bottom of the vehicle is formed with a run-on slope 38 with which an easy joining process is ensured.As can be further seen from FIG. 7 or 8, the upper profile leg 35 of the U-shaped roof system latching profile 33 is extended toward the inside of the vehicle by a protrusion 37 compared to the lower profile leg 34. This forms a roof system mating contour against which a height stop 39 of the reinforcing frame can strike during the joining process.The height stop 39 of the reinforcing frame 40 is realized in FIG. 2 or 3 by a stop flange which is integrally formed on the free upper edge of the reinforcing frame edge web 23. The upper side of the stop flange 39 and of the reinforcing frame latching element 32 are flush with one another in FIG. 7. In FIG. 7 or 8, the stop flange 39 projects beyond the reinforcing frame edge web 23 both toward the inside of the vehicle and toward the outside of the vehicle by an excess s (FIG. 8 ).As can be further seen from FIG. 7 or 8, the core layer 27 of the molded headliner section 14 extends in the opening edge region 9 directly to the stop flange 39 and ends there. In contrast, the elastically compressible decorative layer 28 is extended and covers both the stop flange 39 and the latching element 32.In the undeformed state, the latching element 32 has a latching element height (measured between the latching element side on the top of the vehicle and the latching element side on the bottom of the vehicle), which is dimensioned to be greater than a latching profile height h (FIG. 7 ) between the two profile limbs 34, 35 of the U-shaped latching profile 33. In the assembled position shown in FIG. 7, this results in a clearance-free clamping of the latching element 32 in the U-shaped latching profile 33, specifically with a reduction in the material thickness of the elastically compressible decorative layer 28 and with a buildup of a restoring force.A joining process for mounting the molded headliner portion 14 on the roof system 11 will be described below: Consequently, the molded headliner portion 14 is guided upward in a joining direction F in the vehicle vertical direction z until the reinforcing frame latching element 32 comes into contact with the run-on slope 38 formed on the vehicle-lower profile limb 34. In the further course of the joining process, the reinforcing frame latching element 32 is displaced inward of the vehicle by means of the run-on slope 38 into a release position, with the build-up of an elastic restoring force. After the run-on slope 38 has been overcome, the reinforcing frame latching element 32 displaces into the latching recess 41 of the U-shaped roof system latching profile 33 with the elastic restoring force being dissipated.In FIG. 9, the reinforcing frame 40 is shown in isolation. Accordingly, the reinforcing frame is constructed in several parts from longitudinal struts 43 which are connected to one another by means of transverse struts 45.
