Abstract
A motorizable tilt shade system includes a header system where the header system includes an integral header attachment connection. At least one cord spool is provided within the header system and is connected with at least one suspension cord. A shade is suspended from the at least one suspension cord and a tilt cord pulley is connected with the at least one cord spool. A tilt cord is connected with the tilt cord pulley and with the shade such that the tilt cord and tilt cord pulley cooperate to tilt the shade. A drive shaft receiver is connected with the tilt cord pulley such that movement of the drive shaft receiver moves the tilt cord pulley. A counterbalance assembly including a negative gradient spring is connected to the drive shaft thereby providing an approximately constant tension on the tilt cord pulley.
