DETAILED DESCRIPTION OF THE INVENTION

[0054] An exemplary embodiment, illustrated in FIG. 1, of a motor vehicle 10 according to the invention comprises a body 12 that carries a rear bumper unit 16 on a rear region 14.

[0055] Further, arranged on the rear region is a first exemplary embodiment of a holding device, which is designated 20 as a whole, and which has a carrier unit 22 that is arranged below the bumper unit 16 such that it is hidden by it, wherein the carrier unit 22 comprises, as illustrated in FIG. 2, a transverse carrier 24 that is connected to the rear region 14 by lateral connection elements 26.

[0056] Further, held on the carrier unit 22, in particular in a central region of the transverse carrier 24, is a pivotal bearing unit, which is designated 30 as a whole and on which a pivot element 32 is mounted such that it is pivotal about a pivot axis 36 that extends transversely to a vehicle longitudinal center plane 34 of the body 12, which is at the same time also a longitudinal center plane 34 of the holding device 20 (FIGS. 2 to 4).

[0057] In a first exemplary embodiment, an attachment element carrier 40 extends from the pivot element 32 and comprises a connection arm 38 which extends from the pivot element 32 and to which is connected a receiving body, designated 42 as a whole, wherein the receiving body 42 forms an insertion receptacle 46 that extends therein along a center axis 44, wherein, as illustrated in FIG. 2, insertable in a receiving opening 48 of the insertion receptacle 46 that is opposed to the direction of forward travel is for example, as an attachment element 50, a coupling ball carrier 56 that carries at an end 54 a coupling ball 52 and is insertable in the receiving opening 48 by an opposite end region 58 to the end 54.

[0058] As illustrated in FIGS. 2 and 3, in a working position A the attachment element carrier 40 is arranged relative to the bumper unit 16 such that it lies below a lower edge 18 of the bumper unit 16, that is to say on a side thereof that faces a road surface 28, and thus the insertion receptacle 46 is freely accessible for insertion of the end region 58 of the coupling ball carrier 56, wherein the center axis 44 extends in the vehicle longitudinal center plane or the longitudinal center plane of the holding device 34.

[0059] Because the pivot element 32 is mounted such that it is pivotal about the pivot axis 36 running obliquely to the longitudinal center plane 34, it is possible, as illustrated in FIGS. 3 and 4, to pivot the attachment element carrier 40 from the working position A, in which the receiving body 42 is below the lower edge 18 of the bumper unit 16, under the lower edge 18 and through into a rest position R illustrated in FIG. 4, in which the attachment element carrier 40 and thus in particular also the receiving body 42 lie above the lower edge 18 of the bumper unit 16 such that they are hidden by the bumper unit 16 and are thus arranged outside a visible region of the bumper unit 16 and the body 12, wherein the center axis 44 extends transversely to the vehicle longitudinal center plane 34 or the longitudinal center plane 34 of the holding device 20, and in so doing runs in particular such that it is inclined relative to the direction of the road surface 28.

[0060] As illustrated in FIGS. 2 to 7, arranged on, and in particular integrally formed in one piece with, the connection arm 38 that extends from the pivot element 32 is a holding arm which is designated 60 as a whole and which, in the working position A (FIGS. 2, 3, 5 and 7), forms an upper transverse wall 62 of the insertion receptacle 46 and thus part of the receiving body 42.

[0061] For the purpose of forming the receiving body 42 as a whole, the holding arm 60 is supplemented by a supplementary body 70, which is U-shaped in cross section and has two side cheeks 72 and 74 and a base body 76 that is arranged opposite the holding arm 60, wherein the base 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.

[0062] The side cheeks 72 and 74 abut, laterally in relation to the holding arm 60, against its side faces 64 and 66 extending transversely to the transverse wall 62, and are connected to the holding arm 60 by screws 92 and 94 passing through it.

[0063] Thus, the holding arm 60 and the supplementary body 70 form the receiving body 42, which is firmly connected to the connection arm 38 by the holding arm 60, such that at one end the receiving body 42 is held in one piece on the connection arm 38 by the holding arm 60, and hence the supplementary body 70 achieves enough stability to impart the required stability to the receiving body 42 and also to connect it stably to the connection arm 38.

[0064] Preferably here, both the holding arm 60 and the supplementary body 70 extend over the entire length of the insertion receptacle 46 in the direction of its center axis 44, and are thus able to optimally take up forces acting on the receiving body 42 through the attachment element 50.

[0065] Moreover, in the region of the side cheeks 72, 74 the receiving body 42 is also provided with mutually opposite apertures 96 through which a securing bolt 98, which also reaches through the attachment element 50, is passable in order to fix the attachment element 50 in the receiving body 42.

[0066] In a second exemplary embodiment, illustrated in FIGS. 8 to 11, the elements that are identical to those in the first exemplary embodiment are provided with the same reference numerals, with the result that with regard to these reference may be made to the description of the first exemplary embodiment.

[0067] In the second exemplary embodiment too, the connection arm 38 is provided with a second embodiment of a holding arm 110, which is in particular integrally formed in one piece with the connection arm 38.

[0068] Unlike the first exemplary embodiment, however, the receiving body 112 takes the form of a discrete, self-contained body which embraces and receives the insertion receptacle 46 and which, in the region of the rear insertion opening 48 of the insertion receptacle 46, surrounds it with a reinforcing annular body 114.

[0069] For the purpose of connection to the receiving body 112, the holding arm 110 bears against its longitudinal side, in particular an upper side 122, by a holding portion 124 that takes the form of an upside-down U and is also provided with lateral embracing elements 126, 128, which in a manner adjoining the upper side 122 of the receiving body 112 also abut against the upper region of longitudinal sides 132, 134 of the receiving body 112, and thus embraces the receiving body 112 in the upper region thereof with positive engagement.

[0070] For the purpose of fixing the holding portion 124 to the receiving body 112, it is connected at the outer edge regions thereof by weld seams 142, 144, 146.
