FIELD: construction.
SUBSTANCE: roller blind comprises a row of links (2), every of which comprises a flat link (7), which defines two main surfaces (10, 11), two opposite longitudinal edges (8, 9) and two opposite transverse edges (12, 13), and also eccentric hinged parts (4-6), which are arranged near the longitudinal edges (8, 9). At the same time in each case two links (7) are hingedly connected with each other by means of hinged parts (4-6), at the same time the row of links (2) may be put in a folded condition, in which the links (2) are turned relative to each other, and an unfolded condition, in which links (2) form a flat surface substantially. On the longitudinal edges (8, 9) there are closing facilities (18) provided, by means of which flat links (7) are engaged to each other in the unfolded flat condition of the row of flat links (7).
EFFECT: invention makes it possible to provide for higher resistance of a roller blind to impact effects from outside.
