Description

[0001] The present invention relates to a net wind deflector for a motor vehicle according to claim 1 and to a correspondingly equipped motor vehicle according to claim 7.

[0002] Net wind deflectors of this type are known per se, for example, from DE 195 18 696 A1, DE 10 2004 037 646 A1, and DE 10 2007 051 878 A1, and have proven themselves in practice. However, it has been shown that the nets used sometimes have a wavy appearance when the respective net wind deflectors are deployed, which is not always considered desirable.

[0003] It is an object of the present invention to overcome this disadvantage.

[0004] This object is achieved by a net wind deflector for a motor vehicle roof with a roof opening located in an outer roof skin and closable by means of an adjustable cover, which has a lower frame strut to which a first section of a net is attached, and an upper frame strut which can be extended relative to the lower frame strut and to which a second section of the net is attached, and which is characterized in that the first section has greater elasticity than the second section. Advantageously, the second section of the net attached to the upper frame strut is taut when the net wind deflector is extended in such a way that the formation of waves in the net is effectively prevented.

[0005] In principle, the first section and the second section can be made of different or identical materials. In particular, it is possible to form the first section from a first elastomer and the second section from a second elastomer that differs from the first elastomer. According to a preferred embodiment, the first section and the second section consist of the same material, in particular an elastomer, wherein the greater elasticity of the first section is created by a geometry that differs from that of the second section. Advantageously, the identical materials can create a particularly reliable connection between the first section and the second section.

[0006] The first and second sections can be connected in any suitable way, particularly by force or form. The two sections can be sewn, welded, or glued together. Furthermore, it is possible to form the net with its first and second sections as a single piece.

[0007] The first section can have a constant or varying elasticity along its length, viewed in the direction of the lower frame strut. This advantageously makes it possible to select a different elasticity for the first section in the center of the net wind deflector than in its respective outer areas, in order to avoid waviness of the net across its entire surface.

[0008] According to a preferred embodiment, the first section comprises a textile fabric that is attached to the second section. This advantageously creates an inexpensive, lightweight, and reliable design of the mesh wind deflector according to the invention. The textile fabric itself can be a woven or knitted fabric. In this case, the first section and second section are also attached in the manner previously disclosed.

[0009] According to a further preferred embodiment, the first section, formed as a net, has a different mesh size than the second section. This advantageously allows for the creation of a one-piece net.

[0010] The first section of the mesh wind deflector can preferably be designed to be permeable to air, as this creates a particularly simple structure of the mesh wind deflector which prevents the formation of wrinkles and at the same time has very good acoustic properties.

[0011] A particularly aesthetic net wind deflector is created when the first section has a lower area which is attached to the lower frame strut and an upper area which is substantially flush with the outer roof skin, since in such a case only the net-shaped component of the net wind deflector protrudes above the roof skin when deployed, while the first section remains invisibly below the roof skin.

[0012] In principle, the mesh wind deflector can be connected to the lower frame strut or upper frame strut in any suitable manner. A particularly advantageous, yet secure and reliable, connection is achieved if the second section has a piping at its end remote from the first section, which is received in a piping receptacle located in the upper frame section.

[0013] The above-mentioned object is also achieved by a motor vehicle having a mesh wind deflector of the type disclosed above. The aforementioned advantages apply adequately.

[0014] Below, a detailed, non-prejudicial, particularly limiting, description of an embodiment of the present invention is given with reference to the attached figures. Fig. 1 shows a section of a motor vehicle according to the invention in a perspective view looking from the vehicle interior to the outside, in which a partially sectioned net wind deflector according to the invention is located in the extended position. Fig. 2 represents the Fig. 1 partially shows the mesh wind deflector shown in perspective front view.

[0015] In Fig. 1 partially illustrates a motor vehicle 1 according to the invention. The motor vehicle 1 has a motor vehicle roof 10 comprising an outer roof skin 5, in which a roof opening 15 is located, which can be closed by a cover (not shown here). A sliding roof 20 having a front frame 25 is accommodated in the roof opening 15. As can be seen from the figure, the cover of the sliding roof 20 is open.

[0016] Furthermore, the sliding roof 20 has a net wind deflector 30 with a lower frame strut 35 and an upper frame strut 40, which is in the Fig. 1 is shown in the extended state. The lower frame strut 35 comprises recesses 45 into which corresponding locking hooks 50 engage in order to fasten the net wind deflector 30 in its lower region to the front frame 25. A first section 55 of a net 60 of the net wind deflector 30 is fastened to the lower frame strut 35. A second section 65 of the net 60 is fastened to the upper frame strut 40 by means of a known piping connection, wherein a piping 70 located on the second section 65 is received in a corresponding piping receptacle 75 of the second frame strut 70. The first section 55 has greater elasticity than the second section 65, thereby reliably preventing the net 60 from forming folds, bulges, or waves when extended.

[0017] In the exemplary embodiment shown here, the first section 55 comprises a textile fabric that is attached to the second section 65, for example, by a seam not shown here. In principle, the first section 55 and the second section 65 can have different mesh sizes. In particular, the first section 55 can be designed to be airtight.

[0018] The first section 55 has a lower region 80, which is attached to the lower frame strut 35, and an upper region 85, which is substantially flush with the outer roof skin 5. This means that, when the mesh wind deflector 30 is deployed, the first section 55 does not protrude from the motor vehicle 1 in an imaginary plane formed by the roof opening 15.

[0019] In Fig. 2 is the Fig.The net wind deflector 30 shown in Figure 1 is shown partially in a perspective front view. At its ends spaced from the net 60, known pivot bearing sections 90 are provided, which are operatively connected to corresponding receptacles (not shown here) and enable the same to be extended. This is also achieved, as is known, by preloaded springs 95 when the cover is opened.
