Description

[0001] The invention relates to a holding device mountable on a rear area of ​​a motor vehicle body, comprising a pivot bearing unit that can be mounted fixedly to the rear area of ​​the motor vehicle, in particular a passenger vehicle, by means of a carrier unit, on which a pivot element carrying an attachment element is pivotably mounted about a pivot axis extending transversely, in particular obliquely, to a longitudinal median plane and is thereby pivotable from a working position to a rest position and vice versa, wherein the pivot element is provided by means of a connecting arm with an attachment element carrier having a plug-in receptacle, into which the attachment element can be inserted with an end area and positively fixed, wherein the plug-in receptacle extends with its central axis substantially parallel to the longitudinal median plane in the working position and wherein the attachment element carrier comprises a receiving body.which has a plug-in socket.

[0002] Such holding devices are known from the prior art. The problem with these is to create a simple and effective connection between the connecting arm and the receiving body.

[0003] This problem is solved according to the invention in a holding device of the type described above by providing the connecting arm with a holding arm which is connected to the receiving body.

[0004] The advantage of this solution is that it provides a simple way to create a stable and permanent connection between the connecting arm and the receiving body.

[0005] In principle, the holding arm could run in any direction relative to the receiving body.

[0006] One particularly advantageous solution provides that the holding arm extends parallel to the central axis along the receiving body.

[0007] This solution has the advantage that it allows a simple connection to be made between the holding arm and the receiving body, and moreover, this connection also allows the forces acting on the receiving body to be optimally transferred via the holding arm to the connecting arm.

[0008] In particular, it is provided that the retaining arm forms a wall area of ​​the receiving body that limits the insertion recess.

[0009] This means that the holding arm is integrated into the receiving body and is itself part of the receiving body.

[0010] The holding arm could be integrated into different walls of the receiving body.

[0011] One particularly advantageous solution provides that the holding arm forms an upper transverse wall of the receiving body in the working position.

[0012] Furthermore, the formation of the receiving body is provided for by including a supplementary body which is connected to the holding arm and which forms the further side walls of the insertion receptacle.

[0013] The supplementary body can have any shape. It is particularly advantageous if the supplementary body has a U-shaped cross-section.

[0014] In this case, the advantageous solution consists in the supplementary body having side cheeks adjoining the retaining arm that encompass the wall area formed by the latter on both sides.

[0015] Furthermore, it is advantageously provided that the side cheeks of the supplementary body are connected to the side surfaces of the support arm, thus allowing a stable connection between the support arm and the supplementary body.

[0016] In particular, it is provided that the supplementary body is screwed to the retaining arm.

[0017] Alternatively, it is also conceivable that the supplementary body is welded to the holding arm.

[0018] Another alternative embodiment of the solution according to the invention provides that the holding arm rests against one side of the receiving body.

[0019] This means that the receiving body is a self-contained body and that the holding arm only rests against one side of the receiving body, in particular an outer side of the same.

[0020] Preferably, the holding arm is aligned so that it rests against at least one longitudinal side of the receiving body.

[0021] A particularly stable connection between the holding arm and the receiving body can be achieved by the holding arm having an inverted U-shaped holding section that rests against the receiving body.

[0022] In this case, for example, it is provided that the holding section is provided with lateral surrounds which, at least in some areas, abut the longitudinal sides adjoining the longitudinal side of the receiving body covered by the holding section.

[0023] This means that the receiving body can be supported by the holding section not only in the area of ​​the longitudinal side covered by it, but also by contact with the longitudinal sides that adjoin the covered longitudinal side, so that the receiving body is stabilized relative to the holding section in three directions.

[0024] One particularly advantageous solution involves welding the holding section to the receiving body.

[0025] To enable optimal positioning of the receiving body in the rest position, it is preferably provided that the insertion opening extends with its central axis transversely to the longitudinal median plane in the rest position, the central axis being inclined in particular in the direction of a roadway.

[0029] A in Fig. 1 The illustrated embodiment of a motor vehicle 10 according to the invention comprises a body 12 which carries a rear bumper unit 16 on a rear area 14.

[0030] Furthermore, a first embodiment of a holding device designated as a whole by 20 is arranged at the rear, which has a support unit 22 arranged under and concealed by the bumper unit 16, which, as in Fig. 2 shown, has a cross member 24 which is connected to the rear area 14 by means of lateral connecting elements 26.

[0031] Furthermore, a pivot bearing unit designated as a whole by 30 is held on the support unit 22, in particular in a central area of ​​the cross member 24, on which a pivot element 32 is pivotably mounted about a pivot axis 36 extending transversely to a longitudinal median plane 34 of the body 12, which is also a longitudinal median plane 34 of the holding device 20 ( Fig. 2, Fig. 3 to Fig. 4).

[0032] In a first embodiment, an attachment element carrier 40 extends from the pivoting element 32, comprising a connecting arm 38 extending from the pivoting element 32, to which a receiving body designated as a whole by 42 is connected, forming an insertion recess 46 extending in the receiving body along a central axis 44, in the receiving opening 48 of which lies opposite to the forward direction of travel, as shown in the Fig. 2 shown, for example as an attachment element 50, a coupling ball carrier 56 carrying a coupling ball 52 at one end 54 with an end area 58 opposite the end 54 can be inserted.

[0033] As in Fig. 1 and Fig. As shown in Figure 3, the attachment element carrier 40 is arranged in a working position A relative to the bumper unit 16 such that it lies below a lower edge 18 of the bumper unit 16, i.e. on a side of the same facing a roadway 28, and thus the insertion receptacle 46 for inserting the end region 58 of the coupling ball carrier 56 is freely accessible, wherein the central axis 44 extends in the longitudinal center plane of the vehicle or the longitudinal center plane of the holding device 34.

[0034] Due to the pivotable mounting of the pivot element 32 about the pivot axis 36 which runs obliquely to the longitudinal center plane 34, it is possible, as in the Fig. 3 and Fig. As shown in section 4, the attachment element carrier 40 is moved from the working position A, in which the receiving body 42 is located below the lower edge 18 of the bumper unit 16, under the lower edge 18 into a position in the Fig. 4 to pivot to the rest position R shown, in which the attachment element carrier 40 and thus in particular also the receiving body 42 is concealed by the bumper unit 16 above the lower edge 18 of the bumper unit 16 and is thus arranged outside a field of vision of the bumper unit 16 and the body 12, wherein the central axis 44 extends transversely to the vehicle longitudinal median plane 34 or the longitudinal median plane 34 of the holding device 20 and is inclined in particular in the direction of the roadway 28.

[0035] As in Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. As shown in Figure 7, a retaining arm, designated as a whole by 60, is arranged on the connecting arm 38 extending from the pivoting element 32, in particular integrally formed, which in the working position A ( Fig. 2, Fig. 4, Fig. 5 and Fig. 7) forms an upper transverse wall 62 of the insertion receptacle 46 and thus a part of the receiving body 42.

[0036] To form the entire receiving body 42, the retaining arm 60 is supplemented by a supplementary body 70 with a U-shaped cross-section, which has two side cheeks 72 and 74 and a bottom body 76 arranged opposite the retaining arm 60, wherein the bottom body 76 forms the lower transverse wall 82 of the insertion receptacle 46 opposite the transverse wall 62 and the side cheeks 72 and 74 form the side walls 84 and 86 of the insertion receptacle 46.

[0037] The side cheeks 72 and 74 lie laterally against the retaining arm 60 on its side surfaces 64 and 66 which run transversely to the transverse wall 62 and are connected to the retaining arm 60 by means of screws 92 and 94 which pass through the retaining arm 60.

[0038] Thus, the retaining arm 60 and the supplementary body 70 form the receiving body 42, which is firmly connected to the connecting arm 38 by the retaining arm 60, so that on the one hand the receiving body 42 is held integrally to the connecting arm 38 by the retaining arm 60 and thereby the supplementary body 70 receives sufficient stability, which overall gives the receiving body 42 formed thereby the required stability and also connects it stably to the connecting arm 38.

[0039] Preferably, both the retaining arm 60 and the supplementary body 70 extend over the entire extent of the insertion receptacle 46 in the direction of its central axis 44 and are thus able to optimally absorb the forces acting on the receiving body 42 by the attachment element 50.

[0040] Furthermore, the receiving body 42 is provided in the area of ​​the side walls 72, 74 with opposing openings 96 through which a locking bolt 98, which also extends through the attachment element 50, can be inserted in order to fix the attachment element 50 in the receiving body 42.

[0041] In a second embodiment, shown in the Fig. 8, Fig. 9, Fig. 10 to Fig.11. The elements that are identical to those of the first embodiment are provided with the same reference numerals, so that reference can be made to the description of the first embodiment with regard to them.

[0042] In the second embodiment, the connecting arm 38 is also provided with a second embodiment of a retaining arm 110, which is in particular integrally formed on the connecting arm 38.

[0043] In contrast to the first embodiment, however, the receiving body 112 is designed as a self-contained, independent body that encloses the insertion receptacle 46 and surrounds the insertion receptacle 46 with a stiffening ring body 114 in the area of ​​the rear insertion opening 48.

[0044] For connection with the receiving body 112, the retaining arm 110 rests on its longitudinal side, in particular a top surface 122, with an inverted U-shaped retaining section 124, which is further provided with lateral surrounds 126, 128, which subsequently cause the top surface 122 of the receiving body 112 to rest against the upper area of ​​longitudinal sides 132, 134 of the receiving body 112 and thus form-fittingly encompass the receiving body 112 in its upper area.

[0045] The retaining section 124 is connected to the receiving body 112 at its outer edge areas by welds 142, 144, 146 for fixation.
