Description

Technical Field

[0001] The present invention relates to a retaining device that can be mounted on the rear region of a motor vehicle body. The retaining device includes a pivot support unit that is fixedly mounted on the rear region of a motor vehicle, particularly a passenger car, by means of a carrier unit. On the pivot support unit, a pivot element carrying an additional element is pivotally supported about a pivot axis extending transversely, particularly obliquely, to the longitudinal median plane, and thereby pivotable from a working position to a rest position and from a rest position to a working position. The pivot element is provided with an additional element carrier having an insertion receiving portion by means of a connecting arm. The additional element can be inserted into the insertion receiving portion at its end region and can be fixed by form-locking. In the working position, the insertion receiving portion extends substantially parallel to the longitudinal median plane with its central axis. The additional element carrier includes a receiving body having the insertion receiving portion. Background Technology

[0002] Such retaining devices are known from the prior art. These retaining devices present the problem of creating a simple and effective connection between the connecting arm and the housing. Summary of the Invention

[0003] This task is thus achieved according to the invention in the case of a retaining device of the form described above, i.e., the connecting arm is provided with a retaining arm that is connected to the receiving body.

[0004] The advantages of this solution are evident from the following: it creates a simple and feasible approach to establish a stable and durable connection between the connecting arm and the housing.

[0005] In principle, the retaining arm can extend relative to the container in any direction.

[0006] One particularly advantageous solution stipulates that the arm is kept parallel to the central axis and extends along the containment.

[0007] This solution has the advantage that the connection between the retaining arm and the housing can be established in a simple manner, and that the force acting on the housing can be optimally transmitted to the connecting arm via the retaining arm through the same connection.

[0008] Specifically, this provision specifies that the wall area of ​​the recessed portion of the retaining arm forming the receiving body should be retained.

[0009] This means that the retaining arm is integrated into the container and is itself part of the container.

[0010] Here, the retaining arm can be integrated into different walls of the container.

[0011] One particularly advantageous solution specifies that the transverse wall of the arm forming the housing is maintained in the upper part of the working position.

[0012] In addition, in order to form the receptacle, it is specified that it includes a supplementary body, which is connected to the retaining arm and forms an additional sidewall of the insertion receptacle.

[0013] Here, the supplement can have any shape. It is particularly advantageous that the supplement is constructed in a U-shape in cross-section.

[0014] An advantageous solution in this situation is to have the supplementary body cover the wall area formed by the retaining arm on both sides with a side plate adjacent to the retaining arm.

[0015] Furthermore, it is advantageously stipulated that the side plate of the supplement is connected to the side of the retaining arm, thus enabling a stable connection between the retaining arm and the supplement.

[0016] Specifically, this provision specifies that the supplementary body is screwed to the retaining arm.

[0017] However, one alternative that could be considered is welding the supplementary body to the retaining arm.

[0018] Another alternative embodiment of the solution according to the invention specifies that the retaining arm rests against one side of the container.

[0019] This means that the container is a self-contained body and the arm rests only on one side of the container, especially on its outer side.

[0020] Here, the arm is preferably oriented such that it rests against at least one longitudinal side of the container.

[0021] A particularly stable connection between the retaining arm and the housing is thus achieved, namely, the retaining arm has a retaining section with an inverted U-shaped structure that rests against the housing.

[0022] In this case, for example, it is specified that the retaining section has a side enclosure that at least partially abuts against the longitudinal side of the accommodating body that is covered by the retaining section on the longitudinal side immediately adjacent to the longitudinal side covered by the retaining section.

[0023] Therefore, the container can be supported not only in the region covered by the retaining section, but also by abutting against the longitudinal side immediately adjacent to the covered longitudinal side, thereby achieving stability of the container relative to the retaining section in three directions.

[0024] One particularly advantageous solution specifies that the section is welded to the housing.

[0025] In order to enable optimal positioning of the container in a stationary position, it is preferably specified that the insertion opening extends transversely to the longitudinal intermediate plane with its central axis in the stationary position, wherein the central axis extends obliquely toward the roadway in particular.

[0054] According to the present invention, the motor vehicle 10 is in Figure 1 The embodiment shown includes a body 12 that carries a rear-side bumper unit 16 in a rear region 14.

[0055] Furthermore, in a first embodiment, a retaining device marked with an integral "20" is arranged in the rear area. This retaining device has a support unit 22 arranged below and covered by the bumper unit 16. The support unit, as shown in... Figure 2 As shown, it has a crossbeam 24, which is connected to the tail region 14 by means of a side connecting element 26.

[0056] Furthermore, a pivot support unit, marked integrally with the symbol 30, is maintained on the load-bearing unit 22, particularly in the intermediate region of the crossbeam 24. On this pivot support unit, the pivot element 32 is pivotally supported about a pivot shaft 36 extending transversely to the longitudinal intermediate plane 34 of the vehicle body 12 (which is also the longitudinal intermediate plane 34 of the retaining device 20). Figures 2 to 4 ).

[0057] In the first embodiment, an additional element carrier 40 extends from the pivot element 32, the additional element carrier including a connecting arm 38 extending from the pivot element 32, a receptacle marked 42 being connected to the connecting arm, the receptacle forming an insertion receiving portion 46 extending therein along the central axis 44, in its receiving opening 48 opposite to the forward travel direction (as in...). Figure 2 As shown in the figure, for example, the connecting ball carrier 56, which carries the connecting ball 52 at the end 54 as an additional element 50, can be inserted into the end region 58 which is opposite to the end 54.

[0058] As in Figure 1 and 3 As shown, the additional element carrier 40 is arranged in working position A relative to the bumper unit 16 such that it is below the lower edge 18 of the bumper unit 16, that is, on the side of the bumper unit facing the lane 28, and thus the insertion receiving portion 46 is freely accessible for insertion into the end region 58 of the connecting ball carrier 56, wherein the center axis 44 extends in the longitudinal center plane of the vehicle or the longitudinal center plane of the retaining device 34.

[0059] A pivotable support via pivot element 32 about a pivot axis 36 extending obliquely to longitudinal intermediate plane 34 has the following possibilities (such as in...). Figure 3 and 4 As shown in the diagram, the additional element carrier 40 pivots from the working position A below the lower edge 18 through the ground pivot. Figure 4 In the static position R shown, in the working position, the housing 42 is located below the lower edge 18 of the bumper unit 16. In this static position, the additional element carrier 40, and therefore the housing 42, is covered by the bumper unit 16 and located above the lower edge 18 of the bumper unit 16 and thus arranged outside the field of vision of the bumper unit 16 and the vehicle body 12. The centerline 44 extends transversely to the longitudinal center plane 34 of the vehicle or the longitudinal center plane 34 of the retaining device 20 and extends obliquely toward the lane 28.

[0060] As in Figures 2 to 7As shown, a retaining arm, specifically a one-piece molded retaining arm, is arranged on the connecting arm 38 originating from the pivot element 32, and is integrally marked with 60. In the working position A... Figure 2 The transverse wall 62 of the upper part of the insertion receiving portion 46 is formed in (4, 5 and 7) and thus forms part of the receiving body 42.

[0061] In order to form the entire housing 42, the retaining arm 60 is supplemented by a supplementary body 70 with a U-shaped cross-section, which has two side plates 72 and 74 and a bottom body 76 arranged opposite to the retaining arm 60, wherein the bottom body 76 forms a transverse wall 82 opposite to the transverse wall 62 at the lower part of the insertion housing 46 and the side plates 72 and 74 form side walls 84 and 86 of the insertion housing 46.

[0062] Side plates 72 and 74 abut against the sides 64 and 66 of the retaining arm that extend laterally to the transverse wall 62 on the side of the retaining arm 60 and are connected to the retaining arm by means of screws 92 and 94 passing through the retaining arm 60.

[0063] Therefore, the retaining arm 60 and the supplement 70 form a container 42, which is securely connected to the connecting arm 38 by the retaining arm 60. Thus, the container 42 is held in one piece on the connecting arm 38 by the retaining arm 60, and the supplement 70 thereby obtains sufficient stability, which as a whole gives the container 42 the necessary stability and connects it stably to the connecting arm 38.

[0064] Here, preferably not only is the arm 60 retained, but the supplementary body 70 extends over the entire extension of the container in the direction of its axis 44 and is therefore best able to withstand the force exerted on the container 42 by the additional element 50.

[0065] In addition, the housing 42 is provided with through holes 96 facing each other in the area of ​​the side plates 72, 74, through which the fixing bolts 98 of the additional element 50 can be inserted to fix the additional element 50 in the housing 42.

[0066] In the case of the second embodiment (in) Figures 8 to 11 (as shown in the figure), these same elements as in the first embodiment are provided with the same reference numerals, so that reference can be made to the description of the first embodiment.

[0067] In the second embodiment, the connecting arm 38 is also provided with a retaining arm 110 in a second embodiment, which is in particular molded as a single piece on the connecting arm 38.

[0068] Unlike the first embodiment, the accommodating body 112 is constructed as a self-contained, independent body that encloses the insertion accommodating portion 46 and surrounds the insertion opening 48 at the rear of the insertion accommodating portion 46 with a reinforced annular body 114.

[0069] In order to connect with the container 112, the retaining arm 110 is placed flat on the longitudinal side, especially the top side 122 of the container in the form of an inverted U-shaped retaining section 124. The retaining section is also provided with side surrounding portions 126, 128. The surrounding portions are immediately adjacent to the top side 122 of the container 112 and also abut against the upper region of the longitudinal sides 132, 134 of the container 112, and thus form a locking around the container 112 in the upper region of the container.

[0070] To secure the retaining section 124 to the housing 112, it is connected to the outer edge region of the housing by welds 142, 144, and 146.
