Description

[0001] The invention relates to an air guiding arrangement for a motor vehicle, comprising a carrier part arranged on a body part, on which an air guiding element is provided which can be driven by a pneumatic drive arrangement with at least one air chamber to be actuated, which is arranged on the carrier part in such a way that the air guiding element can be transferred from a retracted basic position to an extended maximum position, wherein at least one pneumatic supply line is provided which pneumatically connects the at least one air chamber to a pneumatic module of the pneumatic drive arrangement via at least one connecting element.

[0002] A generic air guiding device is known from German patent application DE 10 2011 112 514 A1. Here, so-called air hoses are provided as pneumatic supply lines for the air chambers. A disadvantage of this air guiding arrangement is that the supply lines, which are only installed during final assembly of the vehicle with the front section already installed, are susceptible to damage. It should be noted that it is generally known, for example, from German patent application DE 696 12 488 T2, to secure supply lines using fastening elements.

[0003] The object of the invention is therefore to avoid the above-mentioned disadvantage in the most cost-effective and simple way possible.

[0004] This object is achieved in that the at least one pneumatic supply line is fixed to the carrier part via fastening elements, wherein one or two supply lines are provided, wherein the one or two supply lines are each provided for fluid supply and / or fluid removal, wherein at least a first supply line has a connecting line for pneumatically connecting the first pneumatic supply line to the pneumatic module, wherein the connecting line is connected to the first supply line and a connecting element via a T-shaped connecting piece. This makes it possible to fix the supply lines in a desired manner on the carrier part even during pre-assembly. Damage caused by an undefined route of the supply lines can thus be avoided. In addition, the assembly effort during final assembly can be considerably reduced.The special connection of the connecting cable via a T-shaped connecting piece with the first supply cable and a connecting element, which can be made of plastic, for example, makes it easy to provide an integrated kink protection with strain relief, and thus to protect the first supply cable, which is particularly susceptible to damage.

[0005] In a particularly advantageous manner, the first and a second supply line are arranged at least in some areas in a common fastening element.

[0006] The air guide element is advantageously designed as a front spoiler lip.

[0007] In addition, it is possible that at least one power line is provided for supplying and / or controlling electrical components, such as sensors, which is fixed to the support part via fastening elements.

[0008] Both the fastening elements for the supply lines and the fastening elements for the energy lines can be designed as clip-in elements.

[0009] Advantageously, the support part has an edge element at least on one longitudinal side, wherein at least one first supply line is fixed in the region of the edge element.

[0010] The invention is explained in more detail with reference to a drawing, in which Fig. 1 a perspective view of a front area of ​​a motor vehicle, Fig. 2 a sectional view of an extended air guide element of an air guide arrangement, Fig. 3 a plan view of an opened support part of the air guiding arrangement from Fig. 2, and Fig. 4 a detailed view of the support part Fig. 3.

[0011] Fig. 1 shows a front section 2 of a motor vehicle 4. The front section 2 has, in a known manner, a front section 6, on which an air deflector arrangement 8 is provided to optimize driving behavior, particularly at high speeds. The air deflector arrangement 8 extends in the vehicle's transverse direction FQ and terminates with its free ends 10, 12 at longitudinal sections 14, 16 of the front section 6.

[0012] Fig. 2 shows a sectional view in the area of ​​the air guide arrangement 8 of the Fig. 1. A support member 18 of the air guide assembly 8 is provided on the front section 6. An air chamber 20 is arranged on this support member 18, which moves an air guide element 22 from a retracted basic position to an extended maximum position. Fig. 2 shows the maximum position. The number of air chambers (20) is optional.

[0013] In order for the air chamber 20, which is part of a pneumatic drive arrangement 24, to be filled with a fluid, it is connected via at least one pneumatic supply line 26 (see Fig. 3) fluidically connected to a pneumatic module of the pneumatic drive arrangement 24, not shown in detail.

[0014] 28 and 30 denote magnetic elements which ensure secure fixing to the carrier part 18 in a retracted basic position of the air guide element 22.

[0015] Fig. 3 shows a plan view of the opened support part 18. In the normal, assembled state, the support part 18 has a cover element (not shown in detail). Connecting elements 30 are provided in the support part 18, which are connected to a first supply line 26 for supplying fluid to the air chamber 20. Furthermore, a connecting element 32 is provided, which is connected to a second supply line 34 for discharging fluid from the air chamber 20. Furthermore, a power line 36 is shown, which supplies schematically illustrated electrical components 38. The support part 18 has two edge elements 40, 42, wherein the pneumatic supply lines 26, 34 and the power line 36 are fixed in the region of the first edge element 40 and are thus easily protected against damage during transport, after pre-assembly, or during operation.

[0016] Fig. 4 shows in detail how the pneumatic supply lines 26, 34 and the energy line 36 are fixed in the support part 18. Fig. 4 shows a detailed section of the support part 18 from Fig. 3. Fastening elements 44 and 46 designed as clip-in elements are provided for the pneumatic supply lines 26, 34. The clip-in element 44 has two adjacent clip-in openings 48, 50, into which the first supply line 26 and the second supply line 34 are clipped. The clip-in element 46 has only one clip-in opening 52, into which both the first supply line 26 and the second supply line 34 are clipped. The power line 36 is fixed in clip-in elements 54.

[0017] In order to additionally protect the first supply line 26 in particular against damage due to kinking or pulling, a connecting line 56 is provided which is fluidically connected to a connecting element 30 for fluid supply and to the first supply line 26 via a T-shaped connecting piece 58.
