Problems solved by technology

However, laminated woven or woven fibers having what is known as blackening material and which provide a high level of shading cannot be used as a windbreak because these materials do not allow sufficient air to pass through which can also cause buzzing when the associated motor vehicle is running buzzing noise

Embodiment Construction

[0020] figure 1 A motor vehicle 10 is shown with a roof 12 having a roof cutout 14 which can be selectively closed or at least partially exposed by means of a transparent cover element 16 .

[0021] In order to conceal the roof cut-out 14, the roof 12 comprises a roller blind arrangement 18 which figure 2 displayed separately. As a screening element, the roller blind device 18 comprises a roller blind web 20 which is formed from flexible, crimpable, knitted spacer fibers and which can be wound on and unwound from a winding device 22 .

[0022] The winding device 22 comprises guides or bearings 24 arranged on both sides of the roller blind web 20 , formed mirror-symmetrically, fixedly connected to the vehicle and having guide plates on their free end surfaces. The roller blind device 18 therefore does not have a separate winding shaft. However, when opening, that is to say exposing the roof cutout 14 , the roller blind web 20 is wound directly onto the guide or bearing 24 ....

Abstract

The invention proposes a roller blind arrangement for a motor vehicle, comprising a roller blind web (20) by means of which a transparent portion of the motor vehicle can be at least partially shaded, and comprising at least one winding device (22) for winding up the roller blind web (20). The roller blind web (20) is formed from a knitted spacer fabric which comprises a support layer (34) formed from a knitted fabric and a decorative layer (36) formed from a knitted fabric and connected to the support layer (34) via connecting threads which maintain a spacing.

Description

technical field [0001] The invention relates to a roller blind arrangement for a motor vehicle according to the preamble of claim 1 . Background technique [0002] Such roller blind arrangements are known in practice and are used, for example, for screening transparent parts of vehicle roofs or side windows of motor vehicles. It is also conceivable to use such a roller blind arrangement as a lid for a luggage compartment or the like. Such roller blind devices generally comprise a roller blind web made of flexible rollable material, and a winding device with which the roller blind web can be wound to form a winding body. The wrapping device is formed, for example, by a coil spring formed from strip-shaped spring steel and arranged on both side edges of the roller blind web. [0003] In the case of the currently known roller blind devices, the roller blind web itself comprises, for example, woven or woven fibers, which have a certain air permeability and at the same time hav...
