Background technique

Rear spoiler assemblies for motor vehicles of the type mentioned at the outset are known from the prior art. In order to ensure optimum static friction between the wheels of the motor vehicle and the roadway beneath it, it is known to provide the motor vehicle with spoilers or air guide elements which press the motor vehicle against the driving wind. driveway. In particular, the rear spoiler is used to increase the compression force on the rear axle to prevent unintentional snapping of the rear end when cornering at relatively high speeds. For motor vehicles with a sloping or steep rear shape, the rear spoiler is often arranged at the upper end of the rear lid, in particular the rear window. The rear window or the rear cover is often also used here as an attachment element, on which the rear spoiler assembly can be arranged. A corresponding rear spoiler assembly is known, for example, from laid-open document EP 2 436 580 A2. Here, the rear spoiler is screwed onto the attachment and has side spoilers on both sides, which are likewise connected to the rear spoiler and to the attachment by means of screw connections.

Contents of the invention

The object of the present invention is to provide an improved rear spoiler assembly for a motor vehicle, which in particular simplifies assembly and reduces manufacturing costs, without compromising the stability of the rear spoiler assembly.

The objects of the invention are achieved with the rear spoiler assembly according to the invention. This has the advantage that the rear spoiler assembly can be assembled with fewer manual operations (Handgriff) or with fewer assembly steps and that the rear spoiler is secured by the advantageous engagement of the rear spoiler and side spoilers. Higher firmness or stability of the component on the motor vehicle. According to the invention, this is achieved in that the rear spoiler has a holding edge associated with its underside, and the side spoiler has a holding section (Halteabschnitt) for the holding edge, wherein the holding of the rear spoiler The edge can be tensioned between the holding section and the attachment element by means of a screwing device. The holding edge of the rear spoiler can thus be clamped between the holding section and the attachment element. The underside of the rear spoiler is that side of the rear spoiler which is associated with the attachment element during intended use and in particular lies thereon. The tension force acting on the holding edge of the rear spoiler is generated by means of the screwing device (by means of which the side spoiler can be fixed at the attachment element), so that the holding section of the side spoiler is screwed The screw device securely fixes the rear spoiler at the attachment element. Since the rear spoiler is advantageously clamped by the side spoiler on the attachment element, simple assembly is ensured, since fewer connection points which need to be screwed or glued are produced in order to form the rear spoiler assembly securely.

According to a preferred development of the invention, the rear spoiler has an upper shell and a lower shell. The upper shell and the lower shell of the rear spoiler form in particular the outer contour of the rear spoiler and optionally form a cavity or gap therebetween, in which reinforcing elements can also be arranged. Preferably, the lower shell at least roughly forms the underside of the rear spoiler, with which the rear spoiler is mounted on the attachment, while the upper shell at least roughly forms the rear spoiler during driving and travel of the motor vehicle. The part against the wind, the upper shell preferably at least substantially forms the air-guiding element. It is preferably provided here that the upper shell has a retaining edge associated with the underside of the rear spoiler. For this purpose, the upper shell is preferably structurally designed in such a way that it protrudes to the underside of the rear spoiler in the assembled state, whereby the upper shell together forms the underside of the rear spoiler at least in sections and is in particular connected to the holding The edge is constructed in one piece. In particular, the retaining edge is here the section of the upper shell which together forms the underside. This preferred development of the invention has the advantage that the upper shell of the rear spoiler is fixed via the side spoilers, so that the upper shell and the other elements of the rear spoiler, in particular the optional lower shell, are not required additional connections. This advantageously reduces the connection complexity within the rear spoiler, in particular between the upper shell and the lower shell. Optionally, however, additional connections, for example glued or screwed connections, are provided between the elements of the rear spoiler in order to further increase the stability of the rear spoiler. The clamping of the holding section forms here in particular a hybrid fastening, by means of which, in particular, the degree of reliability of the mentioned adhesive connection can be reduced.

According to a preferred development of the invention, the retaining edge has at least one projection associated with the retaining section and the retaining section has a recess configured correspondingly to the projection. If the protrusion is introduced into the recess during assembly, a form-fit connection is thus obtained between the side spoiler and the rear spoiler. A lateral movement of the rear spoiler relative to the side spoiler is thus ensured not only by the static friction obtainable by means of the screwing device but also by the positive fit of the projection inserted into the recess. Optionally, the retaining section and retaining edge have pairs of protrusions and recesses engaging into each other. Alternatively or additionally, the or the other protrusion is formed on the holding section and the or the other recess is formed on the holding edge.

Particularly preferably, the corresponding recess is groove-shaped in such a way that it extends along the holding section. In particular, the groove-shaped recess is formed with an open edge at at least one end, so that a protrusion engaging in the recess can be pushed laterally into the groove-shaped recess and does not have to be inserted only perpendicularly to the direction of extent. In this case, the protrusions are preferably formed in the form of webs, corresponding generally to the groove-shaped recesses, or preferably have a shape different from the webs, for example conical, alternatively spherical or convex protrusions. Particularly preferably, however, the protruding webs are configured in the form of webs, so that an advantageous orientation of the side spoiler relative to the rear spoiler is also achieved by the web-shaped protrusions engaging in the groove-shaped recesses.

According to a preferred development of the invention, the side spoiler is U-shaped in longitudinal section with two opposite legs, wherein a first of the legs serves to support the attachment element with a retaining section and the second of the legs forms the air-guiding element. Thus, one leg is used for fastening the rear spoiler assembly at the attachment and the other leg is used for guiding the air flow, whereby both legs can advantageously be optimally adapted to their respective purposes .

Particularly preferably, the first leg has an opening through which a fastening screw of the screw device can be guided, in particular with a screw shank. As a result, the side spoiler can be screwed directly onto the attachment element via the first leg. This also results in an advantageous introduction of force to the retaining edge of the rear spoiler via the retaining section formed on the first leg.

Preferably, a nut cooperating with the fastening screw is fastened at or in the opening. This in particular achieves the advantage that the screw head of the fastening screw rests against the attachment part at the side of the attachment part facing away from the spoiler, thereby facilitating assembly because the screw head rests on the back of the attachment part. Access is easier on the side than in a side spoiler, in particular U-shaped. In addition, this results in the further advantage that at least the upper shell and/or the side spoiler are at least substantially unrestricted during assembly on the surface of the attachment, in particular by threaded pins or clips protruding from the attachment. can be moved upward, which considerably simplifies its optimal positionability.

Furthermore, it is preferably provided that the side spoiler has an adhesive for fastening to the attachment at a distance from the screw device. An additional fixation of the side spoiler at the attachment element is ensured by gluing at a distance from the screw device. In particular, the adhesive serves to lift the side spoiler at the end spaced from the adhesive so far from the attachment when the screwing device is loosened that it can be loosened Clamping of the spoiler and removal of the rear spoiler from the attachment and side spoiler without the side spoiler being completely removed from the attachment. This results in a simple disassembly of the rear spoiler in order, for example, to maintain or replace the lighting device integrated in the rear spoiler.

Preferably, the rear spoiler assembly has an attachment part that is especially configured as the rear cover of the motor vehicle or a motor vehicle, wherein the retaining edge of the rear spoiler is held tightly on the side spoiler by screwing devices. between the retention section and the attachment element. This results in the advantages already mentioned.

Particularly preferably, the rear spoiler assembly has a further side spoiler which is designed in a mirror-reversed manner relative to the side spoiler described above. A further side spoiler is arranged on the second longitudinal side of the rear spoiler facing away from the first longitudinal side on which the side spoiler is arranged and connected to the rear spoiler and is there connected to the rear The spoiler and the attachment element are connected or connectable by further screwing means of the further side spoiler, as previously described. As a result, the rear spoiler is securely locked on both sides at the attachment element and at the same time a simple detachment of the rear spoiler is enabled, in particular without completely removing the side spoiler from the attachment element.

Detailed ways

FIG. 1 shows an advantageous motor vehicle 1 with a steep rear 2 in a simplified side view. The steep rear part 2 is formed primarily by the decklid 3 carrying the window pane 4 . Arranged at the upper end of the window pane 4 is a rear spoiler assembly 5 which additionally forms the roof line of the motor vehicle 1 . The rear spoiler assembly 5 has a rear spoiler 6 which extends over almost the entire width of the windshield 4 or the decklid 3 and which is supplemented on its longitudinal sides facing away from each other by side spoilers 7 . In FIG. 1 only one of the side spoilers 7 is recognizable due to the side view.

FIG. 2 shows a simplified perspective detail view of the rear spoiler assembly 5 . The side spoiler 7 is advantageously formed on the rear spoiler 6 so that no or only small edges or Interruption (Unterbrechung) occurs. In this case, according to the present exemplary embodiment, the side spoiler 7 extends over the entire length of the rear spoiler 6 , as shown in FIG. 2 .

FIG. 3 shows a schematic sectional illustration of the rear spoiler assembly 5 according to the section line A-A drawn in FIG. 2 .

The rear spoiler 6 has an upper shell 8 , which forms an air guide element 9 guiding the air flow on the upper side of the rear spoiler 6 . At its edge region facing the side spoiler 7 or at its longitudinal side facing the side spoiler 7, the upper shell 8 has a section 10 leading to an attachment element 11 of the motor vehicle, so that the rear spoiler 6 above The shell 8 is placed on the attachment element 11 , as shown in FIG. 3 . The upper shell 8 of the rear spoiler 6 thus leads as far as the underside of the rear spoiler 6 which rests on the attachment element 11 on which the rear spoiler rests. The attachment element 11 is, for example, a trim element of the exterior lining of the motor vehicle 1 or alternatively a window pane 4 .

The section 10 ends with a laterally protruding retaining edge 12 which rests on the attachment element 11 . The retaining edge 12 protrudes in the direction of the side spoiler 7 and has a projection 13 at its free end, which is designed in the form of a web and extends in particular horizontally when it is properly arranged on the motor vehicle 1 . At a distance from the projection 13 at the free end, the retaining edge 12 also has a recess 14 , which runs parallel to the web-shaped projection 13 in the form of a groove on the side facing away from the attachment element 11 .

The side spoiler 7 is designed as a U-shaped profile, such that it has a first leg 15 and a second leg 16 , which are connected to one another via a connecting section 17 . In particular, the connection section 17 and the two legs 15 , 16 are formed in one piece with one another. Alternatively, the two legs 15 , 16 are formed separately and connected to each other, for example by gluing and/or screwing. The legs 15 , 16 lie opposite one another, wherein they run parallel to one another or deviate from a parallel orientation. According to the present exemplary embodiment, the distance between the free ends of the legs 15 , 16 is smaller than the distance between the legs 15 , 16 at the connection section 17 . The legs 15 , 16 therefore run towards each other at their free ends, which results in a flow-technical advantage during operation.

The first leg 15 facing the attachment element 11 has an opening 18 in which a nut 19 is fastened. The fastening screw 20 is guided with its threaded shank 21 through the opening 22 of the attachment element 11 and screwed into the nut 19 such that the head of the fastening screw 20 is on the side of the attachment element 11 facing away from the spoiler 7 It rests against the attachment element 11. By providing this screwing device 23 (which in particular comprises a fixing bolt 20 and a nut 19 fixed at the side spoiler), the side spoiler can thus be fixed at the attachment element 11 and can be mounted on the side spoiler before screwing or gluing. In the framework of the assembly process, movement on the attachment element 11 is advantageously substantially free.

The side spoiler 7 also has a holding section 24 facing the rear spoiler 6, which is designed to cooperate with the holding edge 12 of the rear spoiler 6 in order to fix the rear spoiler 6 at the attachment element 11 or at the 1 motor vehicle.

For this purpose, the holding section 24 has a groove-shaped recess 25 corresponding to the web-shaped protrusion 13 and a web-shaped protrusion 26 cooperating with the groove-shaped recess 14 . During intended use, as shown in FIG. 3 , during assembly, the retaining section 24 is placed on the retaining edge 12 of the upper shell 8 of the rear spoiler 6 in such a way that the protrusion 26 penetrates into the recess 14 and protrudes 13 penetrates into the recess 25 , whereby a form-fit connection is obtained between the side spoiler 7 and the rear spoiler 6 . By tightening the fastening screws 20 , the retaining edge 12 is also clamped or tensioned between the side spoiler 7 , in particular its lower leg 15 , and the attachment element 11 . As a result, the rear spoiler 6 is securely fixed on the attachment element via the side spoiler 7 . Preferably, the rear spoiler 6 is positively connected to the motor vehicle 1 or to the attachment element 11 or to a further attachment element 11 of the motor vehicle 1 via a plug connection at a region remote from the side spoiler 7 and can in particular It is pivotally and displaceably connected thereto, so that if the side spoiler 7 is completely or only partially loosened from the attachment element 11 by unscrewing the screw device 23 , it can be easily and without further aids The rear spoiler 6 is completely removed from the motor vehicle by removing the retaining edge 12 under the retaining section 24 . If the grip obtained by the screwing device 23 is loosened, the rear spoiler 6 can simply be pulled out of the region of the holding section 24 with the holding edge 12 and then swiveled or removed from the motor vehicle 1, for example, so that The tail lights, for example integrated into the rear spoiler 6 , can be accessed and replaced in a simple manner. In particular, the rear spoiler 6 itself is held on the motor vehicle 1 without screwing or screwing only by the side spoiler 7 , which results in simple assembly and disassembly.

Optionally, the side spoiler 7 is fixed on the attachment element 11 by means of an additional adhesive 27 in a section of the leg 15 facing away from or remote from the holding section 24 . By gluing, for example, it is achieved that if the screwing device 23 is loosened, the side spoiler 7 is not completely released from the attachment element but remains there. Furthermore, the adhesive 27 helps to prevent flow noise and the intrusion of wind and/or dirt or moisture in the region between the side spoiler 7 and the attachment element 11 during operation. Optionally, the retaining edge 12 of the upper shell 8 is also designed in such a way that it extends so far below the leg 15 of the side spoiler 7 that it also extends beyond the area of the screw device 23 . For screwing, however, the retaining edge 12 in this case has an additional opening 28 through which the fastening screw 20 and optionally also the nut 19 can be guided. The elongated configuration of the retaining edge 12 is shown by dashed lines in FIG. 3 .

According to the present embodiment, the first leg 15 is generally spaced apart from the attachment element 11 , whereas according to another embodiment it is provided that the leg 15 rests at least partially on the attachment element 11 and only holds the sections 24 offset. It is configured such that the holding edge 12 of the upper shell 8 of the rear spoiler 6 can be arranged between the holding section 24 and the attachment element 11 and be tensioned or clamped when the fastening bolt 20 is tightened.
