DETAILED DESCRIPTION

[0021] In some examples described herein, in order to configure the component which forms the interface, and is used to attach a mounting for an object as compact as possible, the contour for attaching the mounting is formed by the outline of a depression in the component. In this case, the mating contour of the mounting to be attached is then to be designed as an integral molding. In another example, the contour of the component may be formed by the outline of an integral molding, and the mating contour of the mounting to be attached is formed by the outline of a depression.

[0022] In some examples, the contour for attaching the mounting may be configured to have an H-shaped outline. Such an embodiment enables very good retention of an attached mounting, both in the vehicle longitudinal direction and in the vehicle lateral direction.

[0023] Such an effect can be even further enhanced when an H leg of the contour is oriented parallel to a customary driving direction.

[0024] In a case in which a mounting is attached to the component, the material of the mounting may be configured to be softer than the material of the component in the regions of the contour of the component and of the mating contour of the mounting, in some examples.

[0025] Such a configuration may help to prevent the component which forms the mechanical interface for mounting from being damaged by the mounting. It is considerably easier to replace a damaged mounting than to replace the component attached to the switch module.

[0026] Furthermore, such a configuration helps to provide a stable, firm seat of a mounting that is attached to the component when the dimensions of the contour of the component and of the mating contour of the mounting to be attached are selected in such a way that the contour causes the mating contour to be widened or to be compressed.

[0027] In some examples, the component may include connecting points for attaching a steering column shroud. Such an embodiment can facilitate or stabilize the attachment of a steering column shroud.

[0028] Turning to FIG. 1, the drawing illustrates a motor vehicle K in a region of a cockpit thereof. A steering wheel 3 is arranged in front of an instrument panel 1 in this region. The steering wheel 3 is coupled to a steering column LS in terms of movement.

[0029] A switch module 4 for the steering column LS, which surrounds the steering column LS in this location, is configured behind the steering wheel 3, that is, between the instrument panel 1 and the steering wheel 3. Multiple levers 4a, 4b, and 4c extend from the switch module 4, which is equipped with an electronic system not shown in greater detail. The lever 4a is used for indicating a driving direction or for activating high beams, the lever 4b is used for actuating a cruise control system, and the lever 4c is used for actuating windshield wipers.

[0030] An instrument cluster 20 comprising round instruments, which is arranged beneath an instrument cowl 2 of the instrument panel 1, is also apparent behind the steering wheel 3.

[0031] Furthermore, a mechanical interface S is indicated with dotted lines. The interface S is designed as a separate component 5 attached to the switch module 4. The component 5, in turn, is used to attach a mounting 7 for an object O (see also FIG. 6).

[0032] Finally, an electronic steering column lock 8 is indicated with dotted lines in this figure, which is likewise attached to the switch module 4.

[0033] FIG. 2 shows the switch module 4, including the component 5, from above and in a slightly perspective view. It can be seen in the figure that the component 5 is attached to the switch module 4. The switch module 4 includes a through-opening 40, and the component 5 also includes a corresponding opening, for receiving the steering column LS (see also FIG. 1).

[0034] Attachment points 52 are used to attach the component 5 to the steering column lock (steering wheel lock), which is not shown in greater detail here. Furthermore, stud-like connecting points 50 are apparent, which are used to connect the component 5 to a steering column shroud. Finally, attachment points 51 for the aforementioned mounting 7 are apparent in this figure, which are used for the final screw assembly of the mounting 7 fixed by way of two contours 53.

[0035] Based on FIGS. 3 to 5, the component 5 serving as an interface shall now be described in greater detail in an individual representation.

[0036] In the assembly orientation shown in the figures, the component 5 may include a frame-like base body G, which provides a rectangular, in particular square, receiving opening 54 for a portion of a steering column shroud. Furthermore, three attachment points 55, arranged in a triangular shape, for attaching the component 5 to the switch module 4 are present at the frame-like base body G. The attachment points 55 are designed as through-holes. The attachment points 52, which are used to attach the component 5 to a steering column lock, are likewise designed as through-openings.

[0037] In this example, two integral moldings 56 including through-openings 56a are present at the upper side of the base body G. The through-openings 56a serve as centering holes and/or as attachment holes for the steering column shroud.

[0038] Two integral moldings A are integrally formed laterally at the base body G, which point from the base body G toward the back, that is, in a driving direction FR, and include the aforementioned pin-like or stud-like connecting points 50 for the steering column shroud.

[0039] Two downwardly extending, hook-like integral moldings 57 are present in the region of the base body G. A free end of the hook-like integral moldings 57 is located on the inside and is directed upwardly. Openings 57a are introduced at the base of the hook-like integral moldings 57.

[0040] The hook-like integral moldings 57 serve as retaining lugs for pre-clipping the aforementioned electronic steering column lock 8 before it is screwed together with the switch module 4. In this regard, the hook-like integral moldings 57 help to facilitate the assembly of the electronic steering column lock 8 indicated in FIG. 1.

[0041] The aforementioned contours 53 for attaching the mounting 7 (see FIG. 6) will now be described in detail. Each of the contours 53 is formed by the outline of a depression introduced from above into the base body G. The outline of the depression, that is, the contour 53, in particular has an H-shaped design and includes an H leg 53a and two H sides 53b. The H leg 53a is oriented parallel to the driving direction FR.

[0042] In FIG. 6, it can be seen that the mounting 7, which is to be attached to the component 5, includes two downwardly projecting mating contours 72 formed by the outlines of integral moldings. Each mating contour 72 is likewise designed to have an H-shaped outline, corresponding to the contour 53.

[0043] In some examples, the mounting 7 may be designed to be softer, at least in the region of the mating contours 72, than the component 5 in the region of the contours 53. For this purpose, it is conceivable to design the component 5 and/or the mounting 7 as a two-component part. In this way, it can be ensured that the contours 53 are not, or the component 5 is not, damaged when the mounting 7 is plugged into the contours 53 of the component 5.

[0044] The assembly of the mounting 7 is now carried out such that the mounting 7 is plugged with the mating contours 72 thereof from above into the contours 53.

[0045] In some examples, the outside dimensions of the mating contours 72 are preferably selected to be slightly larger than the dimensions of the contours 53. The mating contours 72 are thus slightly compressed when plugged into the contours 53. This helps to ensure that the mounting 7 is retained very firmly and securely in the component 5.

[0046] A final screw assembly of the mounting 7 can be carried out at the attachment points 51 by way of attachment means 6, which are preferably designed as screws. In the process, the mounting 7 rests with a downwardly directed bearing surface on a bearing surface F of the component 5. The bearing surface F of the component 5 is formed by rib-like protrusions in the region of the base body G.

[0047] The H-shaped configuration of the contours 53 or of the mating contours 72 results in a very secure fixation of the mounting 7, both in the vehicle longitudinal direction and in the vehicle lateral direction. Deviating from the exemplary embodiment, the contours 53 (and thus the corresponding mating contours 72) can also have a differently configured outline.

[0048] As can be seen from the figure, the mounting 7, in turn, may be used to mount an object O indicated with dotted lines. The object O can be a smart phone, an MP3 player, or the like, for example. For this purpose, the mounting 7 comprises upwardly directed holding arms 70, which are slightly preloaded to the inside. A vertically extending groove 71 in each of the holding arms 70 is used to insert the object O, wherein the holding arms 70 are moved apart from one another in a slightly spring-loaded manner, and rest with preload against the object O.

[0049] It should be understood by those skilled in the art that other configurations of the mounting 7 are possible. For example, the mounting 7 can be designed with a deposit area located at the top for depositing arbitrary objects, instead of the holding arms 70.

[0050] If the attachment of a mounting 7 should not be desired, the interface S or the component 5 can be covered by the portion of a steering column shroud or interior lining not shown in greater detail.
