Abstract: A Venetian blind includes an elongated top housing, a horizontally disposed shaft journaled in the top housing, a plurality of horizontal slats suspended one above another, a pair of pull ropes wound around the shaft, a bottom rail disposed below the slats, two pairs of tilting cords, and a plurality of suspending strings. Each of the slats has two opposite longitudinal sides and is formed with two through holes. Each of the pull ropes passes through the housing and through a respective one of the through holes of the slats and is mounted to the bottom rail. Each of the pairs of tilting cords is disposed on a respective one of the opposite longitudinal sides of the slats and has an upper end mounted to the shaft and a lower end mounted to the bottom rail. The suspending strings are disposed below each of the slats and connect one of the pairs of tilting cords to the other one of the pairs of tilting cords. Each of the slats includes a slat body with a substantially S-shaped cross-section.
