ABSTRACT:
A roller shade assembly includes a drape bar extending adjacent a rotatably supported roller tube to suspend a portion of a flexible shade fabric windingly received by the roller tube. The drape bar includes a fabric-receiving portion that is shaped along at least a portion of its length to be non-linear so that the suspended portion of the shade fabric defines a curve across its width. The fabric-receiving portion of the drape bar may be continuously curved. Alternatively, the fabric-receiving portion may include substantially straight segments each longitudinally misaligned with adjacently located segments.
