Abstract: A carrier for supporting a slat of a vertical blind. It includes a central section provided with a rotary slat suspender; a drive section provided with an actuating mechanism for rotation of the slat suspender and a connection section provided with a pull-bar, molded solid with the body of the connection section. The slat suspender is made up of two readily detachable parts coming apart when the part holding the slat is subjected to a pull force deemed excessive and dangerous. The drive section includes a combination worm-clutch and drive shaft allowing continued rotation of some of the slat suspenders, when the others have stopped, to permit them to reach the same stop position as the others.
