Abstract

A window blind including a shade suspended from a generally elongated head bar, the window blind including a set of first slats. Each of the first slats having a first slat aperture extending therethrough. A first tilt string defining a pair of first tilt string segments is suspended from the head bar. A set of first supporting strings extends between the first tilt string segments, each of the first supporting strings supporting a corresponding first slat. A first tilt mechanism is attached to the head bar and mechanically coupled to the first tilt string segments for selectively allowing relative vertical movement of the first tilt string segments in opposite direction relative to each other so as to pivot the first slats between open and closed configurations. A
second individually tiltable shade section includes a set of second slats positioned in an underlying relationship relative to the first slats. A second tilt string defines a pair of second tilt string segments suspended from the head bar. The second tilt string segments extend vertically from the head bar through the vertically aligned first slat apertures. A set of second supporting strings extends between the second tilt string segments, each of the second supporting string supporting a corresponding second slat. A second tilt mechanism is attached to the head bar and mechanically coupled to the second tilt string segments for selectively allowing relative vertical movement of the second tilt string segments in opposite direction relative to each other so as to pivot the second slats between open and closed configurations. A biasing loop is provided for biasing the second tilt string segments towards a predetermined second segment spaced relationship relative to each other in a biasing region located between a lowermost first slat and an uppermost second slat. The biasing loop ensures that the second tilt string segments slide freely within the vertically aligned first slat apertures.
