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.
