    Description

    BRIEF DESCRIPTION OF THE DRAWINGS

    [0028] FIG. 1 is a plan view of an exemplary attachment part;

    [0029] FIG. 2 is a side view of the attachment from FIG. 1;

    [0030] FIG. 3 is a side view of the attachment part from FIG. 1 installed in a vehicle; and

    [0031] FIG. 4 is an exemplary mating securing element.

    DETAILED DESCRIPTION OF THE DRAWINGS

    [0032] An exemplary attachment part 1 includes a main body 10. FIG. 1 shows a plan view of an inner side 12 of the attachment part 10. A visible side opposite the inner side 12 is directed into the image plane.

    [0033] Securing elements 20, 22 are arranged on the inner side 12 and serve to mechanically secure the attachment part to the vehicle. Two securing elements 20, 22 are shown as an example; more or fewer securing elements can also be provided.

    [0034] Furthermore, an electrical consumer 30 in the form of a surface heating system is arranged on the inner side 12 of the attachment part 10. The surface heating system has a conductor track structure 32, which is formed as a heating portion and can be heated by applying an electrical power. The conductor track structure is contacted via connection conductor tracks 40, 42. The connection conductor tracks run over the main body 10 and are continued as far as the securing element 20.

    [0035] FIG. 2 shows a side view of the attachment part 1 from FIG. 1. It can be seen that the securing elements 20, 22 each protrude from the inner side of the attachment part 1. The connection conductor tracks 40, 42 are led up on opposite sides of the securing element 20 and extend up into a securing portion of the securing element 20. In the end region, the connection conductor tracks 40, 42 can be widened to enable better contact.

    [0036] To assemble the attachment part 10 on the vehicle, it is secured to a further component 50, which can be part of the vehicle body, for example, see FIG. 3. For this purpose, the securing elements 20, 22 are guided through recesses in the component 50, wherein their securing portions engage with corresponding mating securing elements 60, 62 on the vehicle. In the present case, the securing elements 40, 42 and the mating securing elements 60, 62 are a clamping and latching connection.

    [0037] An exemplary mating securing element 60 is shown in FIG. 4. When the securing element 20 is pushed into the mating securing element 60, the spring structure of the mating securing element 60 ensures that the inner limbs 63, 64 come into contact with the securing element 20. This achieves a mechanical securing. The mating securing element 60 furthermore has detent lugs 68, which press into the inserted securing element 20 and make disassembly more difficult or prevent it.

    [0038] The mating securing element 60 is also formed as an electrical contact. For this purpose, it has a contact connection on each of the inner limbs 63, 64 (in FIG. 4, only one contact connection 66 can be seen on the inner limb 61), which provides an electrical connection to a power supply on the vehicle via cables 70, 72. These contact terminals correspond to the connection conductor tracks 40, 42 on the securing element 20, so that electrical contact is provided when the securing element 20 and mating securing element 60 engage with each other. Consequently, the mechanical securing of the attachment part also results in electrical contact with the surface heating system at the same time.

    [0039] FIG. 5 shows a plan view of a further exemplary attachment part 1A. In addition to the attachment part 1 described in FIG. 1, this attachment part has a capacitive sensor array 80 with a further conductor track structure, not shown in more detail, as well as sensor connection conductor tracks 90, 92, which are routed from the sensor array to the securing element 20 for electrical contacting of the sensor array with a vehicle-side power supply and/or a control unit. The sensor array 80 is configured, for example, to be able to set operating modes of the surface heating system or to be able to switch it on or off.

    [0040] The sensor array 80 can then be electrically contacted analogously to the described contacting of the surface heating system 30. For this purpose, additional electrical contacts would have to be provided on the mating securing element 60, which correspond to the sensor connection conductor tracks 90, 92 on the securing element 20 and provide, for example, an electrical contact to a control unit or the like.

    [0041] The conductor tracks 40, 42, the conductive track structure 32 of the surface heating system 30, the conductor track structure of the sensor array 80, and the sensor connection conductor tracks 90, 92 are preferably printed on the main body 10 using printing technology.
