Embodiment Construction

[0025] In the drawing, a vehicle roof 10 is shown, which is for a passenger car not shown in detail and has a roof opening 12 which can be closed or at least partially opened by means of a transparent cover part, so The transparent cover part is not shown in detail here and belongs to the roof opening system.

[0026] In order to screen the roof opening 12 , the vehicle roof 10 comprises a roller blind arrangement 14 comprising a roller blind 16 made of fabric which can be folded or rolled up.

[0027] On its free end side, the roller blind 16 has a tension bow 18 extending in the transverse direction of the vehicle. The roll blind 16 is secured at its edge facing away from the tension bow 18 to a roll shaft 20 extending in the transverse direction of the vehicle. The reel 20 comprises a reel tube which is rotatably mounted and which is pretensioned in the rolling direction of the roller blind 16 by means of a reel spring not shown in detail here, so that when the tension bow...

Abstract

The invention relates to a roller blind arrangement for a motor vehicle for shading a transparent vehicle section and comprising a roller blind fabric (16) which can be wound on a reel to Forming a roller blind winding, the roller blind arrangement is guided at its lateral edges with respect to the vertical longitudinal center plane of the roller blind in respective guide rails (22A, 22B), the roller blind arrangement also having a drive device having a drive gear (26) for driving two drive structures, each of which is guided in a guide rail (30) of a corresponding one of the guide rails (22A, 22B), the Each of said drive structures is designed as a toothed belt (28A, 28B) having a substantially rectangular cross-section and comprising teeth (32, 34) on at least one side. The roller blind (16) is pressed between the underside of the toothed belt (28A, 28B) and the bottom (42) of the guide rail (30) and moves along the guide rail (22A, 22B). ), the roll shade is deflected in at least an approximately U-shaped manner in the guide track (30) by the toothed belts (28A, 28B); or, the roll shade ( 16) is pressed between the upper side of the toothed belt (28A, 28B) and the top of the guide rail (30), and when viewed in the transverse direction of the guide rail (22A, 22B), the The roller shade is deflected in said guide track (30) by said toothed belts (28A, 28B) in an at least approximately inverted U-shaped manner. The spool (20) has respective ends at either side of the vertical longitudinal center plane of the shade, each end tapering towards a respective lateral edge of said shade fabric (16).

Description

technical field [0001] The invention relates to a roller blind arrangement for a motor vehicle for concealing a transparent vehicle section. Background technique [0002] Such a roller blind arrangement is known from document DE 10 2006 054 881 A1 and comprises a roller blind which can be unrolled from a winding device to hide the transparent roof opening of the relevant motor vehicle or which can be wound on a winding device to open the transparent roof opening. The roller blind is coupled at an edge extending in the transverse direction of the vehicle to a winding device, in particular designed as a reel. At the edges of the roll blind, which are arranged at both sides with respect to the vertical longitudinal center plane of the vehicle, the roll blind has guide strips which are each guided in a corresponding one of the guide rails in the longitudinal direction of the vehicle extend. In this way, the roller blind can be kept tensioned in the transverse direction of the...
