Abstract
A head rail for a mini blind system is disclosed. The mini blind system includes a plurality of pivotable slats supported on flexible ladders that are connected to basket assemblies mounted in the head rail. The head rail includes a pair of sidewalls and a bottom wall. The bottom wall includes flat wall portions and a recessed channel which strengthens the head rail and allows for full pivotable movement of the uppermost mini blind slats. The head rail further includes cross-shaped apertures extending through the recessed channel and configured for locating and receiving the basket assemblies of the present invention. The head rail apertures, as well as the bottom openings on the basket assemblies, include unobstructed cut-out portions which facilitate pivoting of the slats to a position which is very close to a vertical position.
