(10) FIGS. 1 to 5a show a support device for a plurality of geometrically different polymeric, already painted motor vehicle bumpers 100, 200, etc. Said support device is needed in order to assemble additional components on the corresponding motor vehicle bumpers 100, 200, etc, in particular, of an electrical nature, such as, for example, parking sensors, spacers or else also headlamp cleaning nozzles and the like. The support device has a support frame 30 made from metal, a drive 40 arranged on the support frame 30, and five support groups 1, 2, 3, 4, 5 arranged on the support frame 30. Each support group 1, 2, 3, 4, 5 is provided as a support surface for a specific bumper geometry.

(11) As can be learned from the figures, each support group 1, 2, 3, 4, 5 has a total of three disc-shaped support elements 1, 1, 1 or 2, 2, 2 etc. spaced apart from one another, in each case upwardly pointing edge of which 10, 10, 10 or 20, 20, 20 etc. already in the unloaded state has a contour adapted to the geometry of the assigned bumper 100 or 200, etc. The support elements 1, 1, 1 or 2, 2, 2 etc. consist of a material which can be easily cut, for example, a plastic and in each case has a thickness s of 1 to 2 centimeters. By means of the drive 40 the support elements 1, 1, 1 or 2, 2, 2 etc. are now movable in such a manner that only the support elements 1, 1, 1 or 2, 2, 2 etc. of a single support group 1, 2, 3, 4, 5 project upwards such that only the upwardly pointing edges 10, 10, 10 or 20, 20, 20 etc. of these support elements 1, 1, 1 or 2, 2, 2 etc. form the support surface for the motor vehicle bumper 100 or 200 etc. assigned to them. This becomes particularly clear by means of a consideration of FIGS. 3, 3a, 5, 5a.

(12) It can also be seen in particular by means of FIG. 1a, that the contours of the edges 10, 20 etc. of adjacent support elements 1, 1, 1 or 2, 2, 2 etc. of different support groups 1, 2, 3, 4, 5 already differ from one another in the unloaded state due to their adaptation to different bumper geometries 100 or 200 etc. The support elements 1, 1, 1 or 2, 2, 2 etc. are designed in the embodiment to be rigid. FIG. 1a shows that the upwardly pointing edge 10, 10, 10 or 20, 20, 20 etc. of a support element 1, 1, 1 or 2, 2, 2 etc. in a side view has a hill-and-valley profile with a hill b and two valleys t.sub.1, t.sub.2. This hill-and-valley profile forms so to speak, an impression of the concrete motor vehicle bumper geometry at the corresponding support location (see FIGS. 3a and 5a). Depending on the complexity of the component 100, 200 etc. to be applied the profiles can also have both a plurality of hills as well as a plurality of valleys. The figures also show that between two support elements 1, 1 or 1, 1 of the same group 1 in each case a support element 2, 3, 4, 5 or 2,3, 4, 5 of all other support groups 2, 3, 4, 5 is arranged. It can be seen that all support elements 1, 1, 1, 2, 2, 2 etc. are arranged in a row alongside one another and also all are aligned parallel to one another. All support elements 1, 1, 1 etc. of the support group 1 etc. are also arranged in this embodiment offset by the constant distance L to the support elements 4, 4, 4 etc. of another support group 4 etc. (see FIG. 2). This applies analogously to all support groups 1, 2, 3, 4, 5. The vertical movement of the support elements 1, 1, 1 etc. is guided in a common guide device 50.

(13) The drive 40 now has transversely to the alignment of the disk-shaped support elements 1, 1, 1 etc. in the perpendicular y direction a carriage 60 displaceable in the horizontal direction x with three upwardly projecting carriers 61, 62, 63 spaced apart from one another in the direction of travel x, by means of which only the support elements 1, 1, 1 or 2, 2, 2 etc. of a single support group 1 or 2 or 3 or 4 or 5 can be lifted together in the vertical direction y. It can be seen by means of a comparative consideration of FIGS. 1, 2 and 4, that the center distance X of the individual carriers 61, 62, 63 in the direction of travel corresponds precisely to the center distance X between the individual support elements 1, 1, 1 or 2, 2, 2 etc. of each support group 1 or 2 etc. The center distance X between, for example, the two support elements 1, 1 of the support group 1 therefore corresponds to the center distance X between the adjacent support elements 2, 2 of the support group 2 and also the center distance X between the two carriers 61, 62, so that the carriage 60 with the upwardly projecting carriers 61, 62, 63 is suitable for a precision-fit entraining of all support elements 1, 1, 1 or 2, 2, 2 etc. of a support group 1 or 2 etc. It is also clear that the center distances X between the individual support elements 1, 1, 1 or 2, 2, 2 etc. of a support group 1 or 2 etc. are all the same size, therefore, for example, the center distance X between the two support elements 1, 1 is just as great as that between the support elements 1, 1. Correspondingly, the support elements 1, 1, 1 or 2, 2, 2 etc. and also the carriers 61, 62, 63 are uniformly spaced apart from one another along the travel path x. The drive 40 is equipped with a pneumatic motor (not depicted) driving the carriage 60, which can move the carriage 60 horizontally in the x direction and in the vertical direction y (indicated by the double arrow in FIG. 1).

(14) The operation of the support device according to the present invention is now as follows: If a first bumper 100 should be applied to the support device, via the position of the carriage 60 the carriers 61, 62, 63 are positioned precisely underneath those support elements 1, 1, 1, which together form the support group 1 and their upwardly pointing edge 10, 10, 10 in each case is adapted locally precisely to the geometry of said first bumper 100 (see FIG. 2, 2a or 3, 3a). By a vertical lifting of the carriage 60 in the y direction these, and only these support elements 1, 1, 1 are displaced upwards, so that only their upwardly pointing edges 10, 10, 10 together form the support surface for the first bumper 100. In this upwardly displaced position the support elements 1, 1, 1, are locked, for example, by the carriage, so that after this the first bumper 100 can be applied with accurate fit to the support group 1 and then can be processed.

(15) If a second bumper 200 with a geometry deviating from the first bumper 100 is then applied to the support device, at first the carriage 60 is now moved downwards again in the y direction into its travel position and then is moved in the direction of travel x in such a manner that the carriers 61, 62, 63 are positioned directly underneath the support elements 2, 2, 2 forming the support group 2, their upwardly pointing edges 20, 20, 20 are adapted to the local geometry of said second bumper 200. Subsequently, the carriage 60 is lifted again in the y direction, so that now only the support elements 2, 2, 2 are displaced upwards and only their upwardly pointing edges 20, 20, 20 together form the support surface for the second bumper 200. Then said second bumper 200 can also be applied precision-fit to the support device. Since a total of five support groups 1, 2 3, 4, 5 are provided, accordingly five different bumper geometries can be applied to the support device depicted in FIGS. 1 to 5a.

(16) FIGS. 6 and 7 show an alternative embodiment of the invention. In this embodiment the support frame 30 has an angle shape adapted to the curvature of a motor vehicle exterior attachment component 100* with three frame sections 31, 32, 33 angularly aligned with respect to one another. In the embodiment on the center frame section 32 in each case three support elements 1, 1, 1 etc. and on the two outer frame sections 31, 33 also in each case three support elements 1*, 1**, 1*** or 1, 1, 1 etc. of each support group 1 or 2 etc. are arranged (to facilitate an overview only the support elements of the support group 1 are all individually provided with reference numbers). In this connection, the two outer frame sections 31, 33 with the center frame section 32 in each case enclose the angle >0, e.g. =2060. It is clear that the support elements 1*, 1**, 1***, 1, 1, 1, 1, 1, 1 etc. are in each case aligned perpendicularly to the plane of their respective frame section 31, 32, 33, so that the support elements 1*, 1**, 1*** or 1, 1, 1 etc. on the outer frame sections 31, 33 are aligned at the angle to the support elements 1, 1, 1 etc. on the center frame section 32. The movement of the support elements 1*, 1**, 1***; 1, 1, 1; 1, 1, 1 etc. is guided in a common guide device 51. It can be seen that in the embodiment according to FIGS. 6, 7, for example, the group A of support elements 1*, 1**, 1*** of the support group 1, which are arranged on the same frame section 31, are arranged offset by a constant distance L.sub.2 to the group 3*, 3**, 3*** also arranged on said frame section 31 of support elements of the support group 3. This applies to the group B consisting of the support elements 1, 1, 1 as well as the group C consisting of support 1, 1, 1. It should be noted that the basic structure of the group B in this embodiment corresponds to the basic structure of the entire group 1 in the embodiment according to FIGS. 1 to 5a. In FIGS. 6 and 7, however, the groups A, B and C depicted by way of example together form the support group 1. Furthermore, all support elements arranged on the same frame section 31, 32, 33 are arranged in a row alongside one another and are also all aligned in parallel to one another.

(17) The operation of the support device shown in FIGS. 6, 7 is now analogous to the embodiment according to FIGS. 1-5 with the difference that here a separate carriage 60 is assigned to each frame section 31, 32, 33 and thus overall accordingly a total of three carriages 60 are provided for the selective lifting of the support elements 1*, 1**, 1*** etc. The carriages 60 can be driven by a common motor. Alternatively, however, a separate motor can also be provided for each carriage 60 (in each case not depicted). FIG. 6 shows a support device in the initial state and FIG. 7 shows the device with upwardly extended support elements 1*, 1**, 1*** as well as 1, 1, 1 and 1, 1, 1 and applied bumper 100*, wherein the mentioned support elementsas previously describedare in turn adapted to the local geometry of the bumper 100*. While the carriage 60 assigned to the center frame section 32 can in turn be moved horizontally in the x direction and is lifted or lowered in the vertical direction y, the carriages 60 assigned to the outer frame sections 31, 33 are moved offset correspondingly by the angle . This means that the movement of these carriages 60 occurs obliquely to the horizontal x along the depicted directions x* or x and the lifting or lowering of said carriages 60 occurs obliquely to the vertical y along the depicted directions y* or y.

(18) In the embodiments elucidated above a so-called internal assembly always occurs, that is, that the inside of the componenthere of the bumper and thus also its curvaturepoints upwards and is freely accessible. Alternatively, it is also possible to design the support device, so that the outside of the components points upwards and is freely accessible. In the case of a curved component, for example, the bumper 100, 200, 100* depicted in the figures, in this case the curvature would point downwards and in an embodiment analogous to FIGS. 6 and 7 the center frame section would here project upwards, while the two outer frame sections drop correspondingly outwards, in order to adapt to the curvature of the bumper 100, 200, 100* pointing downwards.
