A toothed belt for a movable roof element of a vehicle which may have a toothed belt body made of plastic, a coupling element, and an interface of the toothed belt, which interface is formed by the coupling element, for coupling to the movable roof element, whereinthe coupling element and the toothed belt body are coupled to each other in a form fitting manner.

Shading device for a vehicle interior including a flexible shading structure displaceable between a compactly stored rest position and a deployed shading position and which is provided with a pull-out profile on an end region. The pull-out profile has a central portion and on opposite end sides of the central portion has telescopic shiftable guiding portions which are displaceable in vehicle-related guidances. A shield is disposed on the central portion and is mounted to be movable relative to the central portion between a rest condition and a functional condition, and a forced control device is provided for displacement of the shield in at least one direction between the rest condition and the functional condition to displace the shield in response to a shifting movement of at least one guiding portion.

A roof system for a vehicle includes a sunshade assembly, which comprises a flexible sunscreen having opposed longitudinal and transversal edges and a winding shaft carrying a winding roller configured for winding and unwinding the sunscreen. The roller is provided with an internal spring connected between the roller and the shaft and is preloaded to wind the sunscreen thereon. Two drive cables extend along and are capable of a movement parallel to the longitudinal edges of the sunscreen. The cables are connected to opposite ends of an operating beam for moving it to wind and unwind the sunscreen. A rotatable gearwheel is positioned at only one end of and concentrically fixed to the shaft and is drivably in engagement with one of the drive parts, such that a displacement of said one of the drive parts results in a rotation of the shaft in the same direction as the roller.

Disclosed is a device for operating a system for covering an opening, including a movable end moving between retracted and extended positions in which the system covers at least part of the opening. The device includes: a flexible push strip with first and second ends, connecting, close to the first end, to the movable end of the covering system; a motor driving the push strip, moving the first end between proximal and distal positions. The push strip transmits a push force to the movable end of the covering system. The device also includes two parallel guide rails on top of or facing one another, in which first and second ends of the push strip travel. The drive includes a drive and idler wheel around which the push strip winds, so the push strip is partly in the first guide rail and partly in the second guide rail.

The present invention relates to a window shading apparatus comprising a blind sheet module including a blind sheet which is unwound when pulled in a wound state so as to cover a window of a vehicle and a pair of guide rails, each having one side connected to one side of the blind sheet module, the guide rails respectively guiding movements of the pair of cord units. Each of the guide rails includes a location adjusting unit which is to be fixed after a connecting location with respect to the blind sheet module is adjusted. The window shading apparatus capable of adjusting the installation width according to the present invention can adjust the width corresponding to an installation space, in particular, the installation width, while maintaining the operating performance of the shading apparatus at the same level, thereby improving completeness thereof.

A roller blind for shading a transparent vehicle section having a roller blind web which can be wound up to form a roller blind reel and which is guided in a guide rail at each of its lateral edges on either side of a longitudinal center plane of the roller blind, and two driving means, each of which is guided in a guide track of one of the guide rails. Each driving means is formed by a toothed belt which has a substantially rectangular cross-section and a toothing on at least one side whose teeth run at least approximately parallel to the plane of the unwound roller blind web in the transverse direction of the respective guide rail, the roller blind web being pressed between the toothed belt underside having the toothing and a bottom of the guide track and being deflected in the guide track by the toothed belt.

A roller blind arrangement for a motor vehicle for shading a transparent vehicle section having a roller blind web which can be wound up to form a roller blind winding and is guided at its lateral edges in relation to a vertical longitudinal center plane of the roller blind in each case in a guide rail, as well as a drive device having a drive pinion which drives two driving means each of which is guided in a guide track of one of the guide rails. The driving means are each designed as a toothed belt which has an essentially rectangular cross section and comprises a toothing on at least one side, the teeth of said toothing extending at least approximately perpendicular to the plane of the unwound roller blind web between a lower side of the toothed belt and an upper side of the toothed belt.

A roller blind arrangement for shading a transparent vehicle section having a roller blind web, which can be wound to form a roller blind winding and is guided at its lateral edges in relation to a vertical longitudinal center plane of the roller blind in each case in one guide rail, as well as a drive device having a drive pinion which drives two driving means which are each guided in one of the guide rails. The driving means are in each case designed as a toothed belt. The toothed belt can have at least one flat surface for coupling to the roller blind web, and the driving means are joined within the guide rails to the roller blind web in each case solely via their respective flat surfaces and are detached from the roller blind web in a section arranged between the guide rails and the roller blind winding.
