Abstract
A balanced tilt mechanism for use in a covering for an architectural opening includes an actuator cord having a weighted tassel that cooperates with a tapered bobbin in a tiltable headrail in the covering. A constant tension spring counterbalances the weighted actuator cord so the headrail can be easily tilted between open and opposite closed positions.
