Abstract
A venetian type blind has a bottomrail, a headrail positioned above the bottomrail, a pivot slat positioned between the headrail and the bottomrail and a tilt slat located immediately below the pivot slat. A set of upper ladders extends from the headrail to the pivot slat and carries a set of upper slats. A set of lower ladders extends from the bottomrail to the tilt slat with each lower ladder being connected to a pivot member on the pivot slat. The lower ladders carry a set of lower slats. At least one pivot cord connects the pivot slat to the tilt slat. This arrangement allows the lower slats to be separately tilted to a different position from the upper slats.
