Description

The invention relates to a motor vehicle having a sealing arrangement according to the preamble of claim 1.DE 10 2017 004 868 A1 discloses an elastic piping for a vehicle, in which a profile with at least two elastic end regions is provided, which rest against the body element at a predefined distance from one another. In this case, a plate-shaped region of a seal is supported against the body element.DE 10 2017 114 244 A1 discloses a one-piece weather strip which is attached to an edge section of an opening section of a frameless door of a vehicle.DE 102 51 022 B4 discloses a hollow chamber seal having an elongated sealing body made of a plastic or a rubber-like material, with at least one first hollow chamber. At least one reinforcement is arranged in the wall of one of the hollow chambers, wherein the material of the reinforcement does not or only does not wear appreciably over the useful life of the hollow chamber seal, and wherein the reinforcement is embedded in the material of the sealing body and is designed in the form of a helix with a longitudinal axis parallel to the longitudinal extension of the hollow chamber.DE 10 2015 007 449 A1, for example, discloses a sealing arrangement for a window which has an opening and a pane as known. The pane is to be displaced relative to the opening, wherein the sealing arrangement has an elastically deformable sealing module, which is arranged along an edge of the opening, and at least one adjusting module, which is assigned to the sealing module. The at least one actuating module is designed to arrange a sealing surface of the sealing module on a surface of the pane in a first operating position and to press the sealing surface of the sealing module away from the surface of the pane in a second operating position.Furthermore, DE 10 2016 112 344 A1 discloses a reinforcing device for a motor vehicle door having an inner reinforcing part and an outer reinforcing part spaced apart therefrom. At least one of the reinforcing parts is designed as a hollow chamber profile and at least one reinforcing part is provided with at least one bead which extends at least partially over the longitudinal extent of the reinforcing part.EP 0 612 638 B1 and DE 38 36 687 A1 also disclose respective sealing arrangements which represent the prior art as part of the subject matter of the invention.In the sealing arrangements or the reinforcing device known from the prior art, which is used for sealing an area between a superstructure and a door of a vehicle, it is to be considered disadvantageous that in an area in which the sealing arrangement abuts a transition from an area under the pane of the door to a pane of the door, tilting of the sealing arrangement, in particular of the edge guard, leads to lifting of the seal, whereby a reliable abutting and sealing of the sealing arrangement cannot be ensured in this area.It is the object of the present invention to provide a motor vehicle with such a sealing arrangement, by means of which a particularly advantageous sealing behavior can be realized and, in particular, water and / or acoustic input can be avoided.This object is achieved according to the invention by a motor vehicle having a sealing arrangement with the features of claim 1. Advantageous embodiments of the invention are the subject matter of the dependent claims and the description.One aspect of the invention relates to a motor vehicle having a sealing arrangement of a sealing element having a hollow chamber on a structure of the motor vehicle which is designed, for example, as a self-supporting body. The vehicle has a wing element which can be moved relative to the structure delimiting a passenger compartment and can be moved between a closed position and at least one open position. In other words, the wing element, which is designed, for example, as a door, can be pivoted relative to the body of the vehicle between a closed position and at least one open position. In the closed position, at least a partial region of the door opening is closed by the door. In the open position, the door releases the partial area, so that a person can exit from the interior of the vehicle or enter the interior via the released partial area. In this case, the movable leaf element is sealed from the structure in the closed position by means of the sealing element which is held on the structure and is formed separately from the door and separately from the leaf element and separately from the structure. This means that the wing element, in particular a sealing surface of the wing element, bears directly against the sealing element in the closed position. In contrast, in the open position, the wing element or the sealing surface of the wing element is spaced apart from the sealing element. The sealing element, which is also referred to as the first sealing element, is formed from an elastomer, in particular from a rubber.The sealing arrangement has a support element which is formed separately from the sealing element and separately from the structure and is arranged outside the hollow chamber. This means that the support element is arranged outside the hollow chamber and preferably outside the sealing element as a whole. At least in the closed position of the wing element, the sealing element is supported on the support element toward the passenger compartment of the vehicle. Preferably, also in the open position of the wing element, the sealing element is supported on the support element towards the passenger compartment of the vehicle.The support element is supported at least indirectly on the superstructure at least in the closed position towards the passenger compartment. This means that, in the closed position of the wing element, the supporting element bears against the first sealing element toward the passenger compartment by deformation.In addition, the sealing arrangement has a second sealing element which is formed separately from the sealing element, is held on the structure and is spaced apart from the sealing element. The second sealing element is formed separately from the structure of the vehicle. The second sealing element is preferably formed from an elastomer, in particular from a rubber. By means of the second sealing element, the wing element is sealed against the body of the vehicle in the closed position.It is provided that the support element is directly connected to the second sealing element, in particular is formed integrally with the second sealing element. This means that the support element and the second sealing element are formed by a one-piece body which can be produced, for example, by an injection molding process. In other words, the supporting element and the second sealing element are formed from the same or the same elastomer, in particular rubber. This has the advantage that the support element and the second sealing element can be mounted simultaneously. This results in an advantageous positioning of the support element relative to the first sealing element.According to the invention, it is provided that the first sealing element is part of a sealing unit, which has a base body connected to the first sealing element, by means of which base body the sealing element is held on the structure. In other words, the sealing unit, which is also referred to as edge protection, comprises the first sealing element and the base body. The base body has a plug-in receptacle reinforced by a metal, which can be plugged onto a flange of the structure, which flange is referred to as a plug-in flange and / or a body flange. In other words, the flange of the superstructure is inserted into the plug-in receptacle of the base body of the sealing unit, so that the base body or the sealing unit is fastened to or on the flange and thus to the superstructure of the vehicle. In order to be able to fasten the base body or the sealing unit stably to the structure and at the same time to ensure reliable sealing of the sealing element, the base body is formed from a first plastic, in particular rubber, and the first sealing element is formed partially from a second plastic, in particular rubber.Furthermore, it is provided that the support element is supported on the superstructure at least in the closed position towards the passenger compartment by means of the base body. In other words, the support element is supported on the structure via the base body in the closed position of the wing element. This means that the base body is arranged between the flange of the superstructure and the support element, so that the support element abuts the base body, which in turn is attached to the flange.One embodiment provides that the base body of the sealing unit has a greater hardness than at least a part of the sealing element. In other words, the base body has a greater hardness than that part of the first sealing element which, in the closed position of the wing element, bears directly against the wing element. The first sealing element thus has a sealing lip which, in the closed position of the wing element, bears directly against the wing element and which is formed from a soft plastic. This means that the plastic from which the base body of the sealing unit is formed is a first plastic, in particular rubber, and at least a part of the first sealing element is formed from a second plastic, in particular rubber, which is different from the first plastic. The second plastic is softer than the first plastic. That is, the second plastic has a lower hardness than the first plastic. Consequently, the sealing lip, which delimits the hollow chamber at least partially, in particular at least predominantly or completely, is formed from a second plastic, which permits a greater deformation than the first plastic.In an advantageous embodiment of the invention, it is provided that the supporting element is arranged in a longitudinal region of the sealing element and the longitudinal region, in the closed position of the wing element, bears directly against an inner side of a pane of the wing element facing the passenger compartment. The leaf element or the door has a body shell and a transparent pane, in particular a side pane. In the present case, the leaf element or the door is designed as a frameless door. This means that the pane or the window opening is bounded in the closed position of the door by the structure of the vehicle and by the door, in particular by the edge of the door. Furthermore, the pane is displaceable or movable relative to the body shell of the door in the vertical direction of the vehicle. Thus, the pane can be moved into and out of the window shaft relative to the body shell. This means that the supporting element, in the closed position of the door and when the pane is raised or closed, bears against the side of the pane facing the passenger compartment.In a particularly advantageous embodiment of the invention, it is provided that the supporting element is arranged at the height of a curb or above the curb of the leaf element designed as a side door in the vehicle vertical direction, wherein the supporting element is arranged at most 20 centimeters, in particular at most ten centimeters, above the curb in the vehicle vertical direction. This means that the supporting element is arranged in particular in a region in which the sealing arrangement abuts a transition from the flange edge to the pane of the wing element in the vehicle vertical direction. This prevents the sealing arrangement, in particular the first sealing element, from tilting in and thus lifting off of the sealing arrangement when the wing element is closed, as a result of which reliable contact and sealing of the sealing arrangement can be ensured in this region.Further features of the invention are evident from the claims, the figures and the description of the figures. The features and combinations of features mentioned above in the description and the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures can be used not only in the respectively specified combination but also in other combinations or alone.The invention will now be explained in more detail on the basis of a preferred exemplary embodiment and with reference to the drawings. The following are shown: FIG. 1 shows a side view of part of a vehicle with a sealing arrangement, and an enlarged detail; and FIG. 2 shows a part of the sealing arrangement of the vehicle, and a window pane; and FIG. 3 shows a perspective sectional illustration of the sealing arrangement; and FIG. 4 is a schematic and perspective sectional view of the sealing arrangement fastened to a flange of the body of the vehicle; and FIG. 5 shows a perspective sectional illustration of a further embodiment of the sealing arrangement.Identical or functionally identical elements are provided with the same reference numerals in the figures.FIG. 1 shows a side view of part of a passenger car with a sealing arrangement 1 and an enlarged detail thereof. The side view shows a part of the left side of the vehicle in the direction of travel, in particular the sealing arrangement 1, the wing element 6, the pane 7, the curb 12 and the rear pane 15. In addition, the enlarged detail shows the first sealing element 2 and the second sealing element 3, and a disk 7.FIG. 2 shows a part of the sealing arrangement 1 of the vehicle, as well as a pane 15 detached from the structure of the vehicle. This means that the sealing arrangement 1 with the second sealing element 3 and the pane 15 are shown in the unmounted state or alone. The glass 15 of the vehicle is also referred to as a rear glass 15 because it is disposed in a region behind a pillar of the body of the vehicle.FIG. 3 shows a sectional perspective view of a sealing arrangement 1 on a structure of a vehicle. The structure which delimits a passenger compartment of the vehicle is designed, for example, as a self-supporting body. The passenger compartment of the vehicle is also referred to as a passenger compartment or interior compartment. The vehicle has, in its completely produced state, at least one wing element 6 which can be moved relative to the superstructure and can be moved between a closed position and at least one open position. The wing element 6 of the vehicle is designed, for example, as a door, in particular as a side door, and in particular as a frameless side door. In the closed position of the leaf element 6, at least a partial region of the door opening is closed by the door 6. This partial area is released in the open position by the door 6. As a result, in the open position of the door 6, a person can exit from the interior of the vehicle or enter the interior via the exposed partial region of the door 6. The wing element / door 6 is sealed against the body of the vehicle in the closed position by means of the sealing arrangement 1 held on the body of the vehicle.The sealing arrangement 1 comprises a first sealing element 2 and a second sealing element 3. The first sealing element 2, which has a hollow chamber 10 and a sealing lip 8, is a component of a sealing unit 5, which has a base body 9 connected to the first sealing element 2, by means of which the sealing element 2 is held on the body of the vehicle. The sealing lip 8 delimits at least partially, in particular at least predominantly or completely, the hollow chamber 10. This means that the sealing lip 8, which in the closed position of the wing element 6 directly abuts the wing element 6, is formed from a soft plastic. The base body 9 has a plug-in receptacle 11 reinforced by a metal, which can be plugged onto a flange 13 of the superstructure. In other words, the flange 13 of the superstructure is inserted into the plug-in receptacle 11 of the base body 9 of the sealing unit 5, so that the base body 9 or the sealing unit 5 is fastened to or on the flange 13 and thus to the superstructure of the vehicle. The second seal member 3, which is formed separately from the first seal member 2 and spaced apart, is supported on the body of the vehicle. By means of the second sealing element 3, the wing element 6 is sealed against the body of the vehicle in the closed position.The sealing arrangement 1 has a support element 4 which is formed separately from the first sealing element 2 and separately from the structure and is arranged outside the hollow chamber 10. The support element 4 is directly connected or formed to the second sealing element 3 and is supported at least in the closed position, not shown in the figures, toward the passenger compartment by means of the base body 9 on the body of the vehicle. The supporting element 4 is arranged in a longitudinal region of the second sealing element 3, which, in the closed position of the wing element 6, bears directly against an inner side of the pane 7 of the wing element 6 facing the passenger compartment. The pane 7, which is bounded by the structure of the vehicle and by the wing element 6, in particular by the edge 12, in the closed position of the wing element 6, is preferably designed to be transparent to light. In order to be able to ensure reliable sealing of the sealing arrangement 1, the supporting element 4 is arranged at the height of the flange 12 or above the flange 12 of the wing element 6 designed as a side door in the vertical direction of the vehicle.FIG. 4 shows a schematic and perspective sectional illustration of the sealing arrangement 1 fastened to a flange 13 of the structure of the vehicle. The plug-in receptacle 11 of the base body 9 is plugged onto the flange 13 of the superstructure, as a result of which the sealing unit 5 is fastened to or on the flange 13 and thus to the superstructure of the vehicle. In the closed position of the wing element 6, the support element 4 is supported on the structure via the base body 9, wherein the first sealing element 2 is supported on the support element 4 towards the passenger compartment of the vehicle. In the closed position of the wing element 6, the sealing lip 8 of the first sealing element 2 is thereby deformed towards the passenger compartment of the vehicle. The deformed sealing lip 14 is shown in dashed lines in FIG. 4. The support element 4 partially limits the deformation of the sealing lip 14, whereby tilting of the first sealing element 2 can be prevented. In this case, the deformed sealing lip 14 of the first sealing element 2 bears against the pane 7 and against the flange 12 of the leaf element 6, as a result of which sealing of the passenger compartment with respect to the environment of the vehicle can be ensured at the transition from the flange 12 to the pane 7.FIG. 5 shows a perspective sectional illustration of a further embodiment of the sealing arrangement 1, in particular the part of the sealing arrangement 1 in which the sealing arrangement 1 bears at a transition from the flanged edge 12 to the pane 7 of the wing element 6 in the vehicle vertical direction. This means that, in particular, the first sealing element 2, in another embodiment, rests with its sealing lip 14 above the edge 12 against the pane 7 of the leaf element 6 and below the edge 12 against the door cladding directed towards the passenger compartment or against the inside of the window duct seal of the leaf element 6.List of reference characters1 Sealing arrangement 2 First sealing element 3 Second sealing element 4 Supporting element 5 Sealing unit 6 Wing element 7 Pane 8 Sealing lip 9 Base body 10 Hollow chamber 11 Plug-in receptacle 12 Flange 13 Flange 14 Deformed sealing lip 15 Rear pane
