CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims the priority, under 35 U.S.C. §119, of German application DE 10 2007 028 163.5, filed Jun. 20, 2007; the prior application is herewith incorporated by reference in its entirety. 
     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to a rear lid for closing a rear compartment of a passenger vehicle. The rear lid, when fitted, being attached to the vehicle and being composed of an inner part and an outer part. The rear lid contains a spoiler device which can be displaced between an inoperative position and an operative position and interacts with an adjustment device. 
     European patent EP 0 250 716 B1 discloses a rear lid which contains a lid body of shell-type construction, with an inner shell which faces the rear compartment which is to be closed and with an outer shell which faces away from the rear compartment and completely covers or clads the inner shell. The lid body contains a cutout which is enclosed on all sides and in which a spoiler device is disposed. The latter is attached to the lid body in a manner such that it can be adjusted between an inoperative position and an operative position. Furthermore, an adjustment device is provided for adjusting the spoiler device which is attached to the inner shell and therefore to the lid body via an auxiliary frame. The production of a vehicle which has a rear compartment and a rear lid of this type can be carried out, for example, in such a manner that first of all the lid body, i.e. the inner shell and the outer shell which is fastened thereto are fastened to the vehicle body via hinges. The vehicle body together with the lid body attached thereto is subsequently painted. After the painting, the remaining components of the rear lid, i.e. in particular the spoiler device and the adjustment device and, if appropriate, a fan and a locking clamp, are attached to the lid body. 
     SUMMARY OF THE INVENTION 
     It is accordingly an object of the invention to provide a rear lid that overcomes the above-mentioned disadvantages of the prior art devices and methods of this general type, which is distinguished in particular by simplified producibility. 
     With the foregoing and other objects in view there is provided, in accordance with the invention, a rear lid for closing a rear compartment of a passenger vehicle, the rear lid, when fitted, being attached to the passenger vehicle. The rear lid contains an inner part being an assembly carrier forming a supporting structure of the rear lid; an adjustment device fastened to the assembly carrier; and an outer part having a panel device and a spoiler device. The spoiler is displaced by the adjustment device between an inoperative position and an operative position. 
     The invention is based on the general concept of equipping the rear lid with a self-supporting assembly carrier to which all of the remaining components of the rear lid are fitted. A preassemblable unit is thereby formed, which simplifies the production of the vehicle equipped with the rear lid. In particular, the unit which is preassembled in this manner can be fitted to the already painted vehicle body. In order to be able better to adapt the visual impression of the rear lid here to the painted vehicle body, the spoiler device extends over the entire width of the rear lid, as measured transversely with respect to the longitudinal direction of the vehicle. The spoiler device therefore covers the outer side of the assembly carrier over the entire width, and therefore painting of the assembly carrier is not required. The remaining region of the outer side of the assembly carrier is covered in this case by a panel device which likewise extends over the entire width of the rear lid. 
     This construction results in a further simplification of the assembly, since the spoiler device, when fitted, only has to be aligned in relation to the vehicle body in order to produce the desired gap sizes. In the case of the known rear lid which is described further above, the spoiler device has to be aligned in relation to the lid body. In addition, the lid body has to be aligned in relation to the vehicle body in order to obtain the desired gap sizes. 
     According to a particularly advantageous embodiment, the panel device can have a panel carrier which is fastened to the assembly carrier, and at least one panel body which is fastened to an outer side of the panel carrier, which outer side faces away from the assembly carrier. The use of different panel bodies therefore enables different variants of the panel device to be realized. The panel carrier remains identical, as a result of which the diversity of parts can be reduced and the costs for forming variants can be lowered. 
     In accordance with an added feature of the invention, at least one of the panel bodies is configured as a luminous band. 
     In accordance with an additional feature of the invention, the adjustment device is directly fastened to the assembly carrier. In addition, a fan is directly fastened to the assembly carrier. Furthermore, a locking clamp is directly fastened to the assembly carrier. Hinges are also directly fastened to the assembly carrier. 
     In accordance with another feature of the invention, the assembly carrier is a single-piece diecast part made from a metal alloy such as aluminum or magnesium alloy. 
     With the foregoing and other objects in view there is provided, in accordance with the invention, a method for producing a passenger vehicle with a tailgate. The methods includes the steps of preassembling an adjustment device on an assembly carrier resulting in a preassembled assembly carrier; fitting the preassembled assembly carrier to a painted vehicle body; and fitting a spoiler device to the preassembled assembly carrier fitted to the painted vehicle body. 
     In accordance with a concomitant mode of the invention, during the preassembling of the assembly carrier step, there is the step of fitting at least one of a panel device, a panel carrier, panel bodies, a fan, a locking clamp and hinges to the assembly carrier. 
     It goes without saying that the features mentioned above and those which have yet to be explained below can be used not only in the respectively stated combination but also in different combinations or on their own without departing from the scope of the present invention. 
     Other features which are considered as characteristic for the invention are set forth in the appended claims. 
     Although the invention is illustrated and described herein as embodied in a rear lid, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims. 
     The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings. The same reference numbers referring to identical or similar or functionally identical components throughout the drawing.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring now to the figures of the drawing in detail and first, particularly, to  FIGS. 1-3  thereof, there is shown a rear lid  1 , with the aid of which a non-illustrated rear compartment of a passenger vehicle, in particular a sports car, can be closed. The rear lid contains a spoiler device  2 , a panel device  3  and an assembly carrier  4  which can be seen in  FIG. 2 . The assembly carrier  4  forms, as it were, an inner side of the rear lid  1 , which inner side, when the rear lid  1  is fitted, faces the rear compartment which is to be closed. In contrast thereto, the spoiler device  2  and the panel device  3  form an outer side of the rear lid  1 , which outer side, when the rear lid is fitted, faces away from the rear compartment. As can be seen, the spoiler device  2  and the panel device  3  each extend over the entire width of the rear lid  1 , as measured transversely with respect to a longitudinal direction  5  of the vehicle, which direction is illustrated symbolically in  FIG. 1  by an arrow. 
     Furthermore, the panel device  3  is disposed on a rear side, i.e. to the rear with respect to the direction of travel of the vehicle, adjacent to the spoiler device  2  on the assembly carrier  4 . However, the panel device  3  may also be disposed in front of the spoiler device  2 . 
     In the fitted state, the assembly carrier  4  is attached to the vehicle in a manner such that it can be pivotably adjusted. For this purpose, non-illustrated hinges are attached to the assembly carrier  4 . The assembly carrier  4  has an outer side  6  which, in the fitted state, faces away from the rear compartment and, in  FIGS. 2 ,  10  and  11 , faces an observer. The assembly carrier  4  may be produced as a cast component. For example, it may here be a diecast part made from a light metal alloy, preferably from an aluminum or magnesium alloy. Similarly, the assembly carrier  4  may be configured as a plastic injection molded component or as a pressed component. Furthermore, it is possible to configure the assembly carrier  4  as a sheet-metal shaped part, preferably made from a light metal sheet. 
     The spoiler device  2  is disposed on the outer side  6  of the assembly carrier  4 , to be precise in such a manner that it can be adjusted between an inoperative position, shown in  FIGS. 1 ,  4  and  5 , and an operative position. In the inoperative position, the spoiler device  2  is integrated into the contour of the rear lid  1  and, when the rear lid  1  is closed, into the contour of the vehicle body. In the operative position, the spoiler device  2  is deployed. For example, the spoiler device  2  extends essentially horizontally in its operative position on the vehicle when the rear lid  1  is closed. The spoiler device  2  forms a spoiler in its operative position. In order to be able to adjust the spoiler device  2  between the inoperative position and the operative position, an adjustment device  7  (illustrated in  FIG. 14 ) which is likewise attached to the assembly carrier  4  is provided. The adjustment device  7  can have, for example, an adjustment drive  8  which is coupled via suitable connecting elements  9 , such as, for example, Bowden cables or flexible rotary shafts, to actuating elements  10  to which the spoiler device  2  is fixedly connected. 
     The spoiler device  2  has, in the customary manner, air inlet openings (not referred to specifically) in order to be able to introduce air through the spoiler device  2  and through the rear lid  1  into the rear compartment in which, for example, a driving unit of the passenger vehicle may be disposed. In this case, the assembly carrier  4  has at least one passage opening  11 . In the example shown, the assembly carrier  4  has at least three relatively large passage openings  11 . Furthermore, a fan  12  which makes the desired circulation of air possible is fastened here to the assembly carrier  4 . In this case, the fan  12  is fastened directly to the assembly carrier  4  and is disposed on an inner side of the assembly carrier  4 , which inner side faces the rear compartment. 
     Since both the spoiler device  2  and the panel device  3  extend over the entire width of the assembly carrier  4 , the latter is completely covered on its outer side  6  by the spoiler device  2  and by the panel device  3  at least in the inoperative position of the spoiler device  2 . Painting of the assembly carrier  4  in line with the color of the vehicle body is therefore not required. 
     The panel device  3  is configured in such a manner that it can be produced as simply as possible in a plurality of variants in order also to be able to realize different variants of the rear lid  1 . Accordingly,  FIG. 4  shows the variant, which is already shown in  FIGS. 1 to 3 , of the rear lid  1  and of the panel device  3  while  FIG. 5  shows a different embodiment of the rear lid  1  which is referred to below by  1 ′, and of the panel device  3 , which is referred to below by  3 ′. According to  FIGS. 3 to 9 , the panel device  3  or  3 ′ contains a panel carrier  13  which is fastened to the assembly carrier  4 , to be precise to the outer side  6  thereof. Furthermore, the panel device  3  or  3 ′ contains at least one panel body  14  or  15  and  16 . In the embodiment shown in  FIG. 4 , only one panel body  14  is provided. In contrast thereto, the embodiment reproduced in  FIG. 5  shows two panel bodies  15  and  16 . The particular panel body  14 ,  15 ,  16  is fastened to the panel carrier  13  on an outer side  17  which faces away from the assembly carrier  4 . 
       FIG. 7  shows the one panel body  14  which is used in order to realize the embodiment shown in  FIG. 4 . The single panel body  14  used in this case extends over the entire width of the rear lid  1  and, as a result, clads the entire panel carrier  13  and that section of the assembly carrier  4  which is assigned to the panel device  3 . 
     The variant shown in  FIG. 5  has precisely two panel bodies  15 ,  16 . It is clear that, in principle, three or more panel bodies may also be provided. The two panel bodies  15 ,  16  extend in each case over the entire width of the rear lid or tailgate  1  and, accordingly, are disposed adjacent to each other in the longitudinal direction  5  of the vehicle.  FIG. 8  shows the panel body  15  which, in the fitted state, is directly adjacent to the spoiler device  2  while  FIG. 9  shows the panel body  16  which is disposed at a distance from the spoiler device  2 . The panel body  16  may be, for example, a luminous band which, for example, is configured to be reflective. 
     In the same manner as the panel carrier  13 , the panel bodies  14 ,  15 ,  16  may be produced from plastic. The spoiler device  2  may also be produced from plastic. 
     In the same manner as  FIG. 2 ,  FIG. 10  shows the assembly carrier  4  in a preassembled state with the spoiler device  2  missing. In the assembly state, the assembly carrier  4  together with the components attached thereto forms a preassembled unit  18  which can be fitted in its entirety to the vehicle body. In order to produce the unit  18 , the assembly carrier  4  according to  FIG. 11  is equipped with the individual components which are reproduced by way of example in  FIGS. 12 to 14 . The assembly carrier  4  according to  FIG. 11  is therefore provided with the panel device  3  which is shown in  FIG. 12  and, for its part, can form a preassemblable unit. Furthermore, the fan  12  according to  FIG. 13  can also be fastened to the assembly carrier  4 . Furthermore, the adjustment device  7  shown in  FIG. 14  can be attached to the assembly carrier  4 . Moreover, a non-illustrated locking clamp can be attached to the assembly carrier  4  and can be used to lock the tailgate  1  to the vehicle body in the closed position. In addition, the hinges already mentioned further above can be attached to the assembly carrier  4  and are used to mount the tailgate  1  pivotably on the vehicle body. 
     When the tailgate  1  presented here is used, the vehicle to be equipped therewith can preferably be produced as follows. First of all, the unit  18  which generally contains the entire tailgate  1  without the spoiler device  2  is preassembled. The preassembled unit  18  is subsequently fitted on the vehicle which has already been painted previously or on the vehicle body which has been painted in advance. The spoiler device  2  is subsequently fitted to the assembly carrier  4  which is already fitted on the vehicle. 
     It is likewise possible to preassemble the spoiler device  2  on the unit  18  and then to fit the complete rear lid to the painted vehicle. 
     Painting of the tailgate  1  or of part of the tailgate  1  together with the vehicle body is not required. It is clear that those components of the tailgate which form the outer side of the tailgate  1 , i.e. the spoiler device  2  and the panel device  3  or at least one of the panel bodies  14  or  15 , can likewise be painted in the color of the vehicle.
