The roller blind (100) detachably fastened to a winding axis (50) can be rolled up on to and unrolled from the winding axis with the aid of pull cords, in which case the pull cords (20, 120, 220) are constructed in the form of U-like routed pull cord pairs (21, 121, 221) passed through guide rings (30, 31, 130, 131, 230, 231) with concentric pull cord connecting sections (24, 124, 224) proceeding parallel to the longitudinal axis of the winding shaft (50) and located on top of each other, which are seized for the rolling up and the unrolling operation of the window shade by a pull cord entrainment means (60) secured concentrically to the circumference of the winding axis (50).
