This invention provides an improvement for a roller blind, particularly for use as a blackout shade. The roller blind includes a spring-biased roller bar and a blind rolled on the roller bar and having along its lateral edges guide members guided in tracks in guide rails disposed at both sides of the window opening, and a bottom bar. The improvement is a brake device for retaining the bottom bar in an arbitrary position against the effect of the bias-force by a cord arrangement. The cord arrangement includes a cord which, at the bottom of one guide rail, is passed through the guide rail, the bottom bar, and the other guide rail to a fixture at the top thereof. A friction mechanism acting on two pins of the cord is mounted in the bottom bar over which the cord is passed in an S-shape. To ensure parallel guidance of the bottom bar in relation to the roller bar, the cord arrangement may include two cords mounted in mirror-image inversion.
