ABSTRACT:
A slatted window-blind construction in which the system for controlling the inclination of the slats comprises at least one group of rigid supporting elements each mounted to pivot about a swivelpin extending from the rectilinear edge associated with the groove of one of a group of thin elements to cooperate with an abutment extending from the free edge of the lower adjacent thin element, and a connecting means fastening the free ends of these supporting elements to one another to control simultaneously their pivoting and inclination and/or the mutual interconnection of the thin elements each time these latter are in an unfolded position.
