Claim:
A window covering comprising: a mounting device; a roller attached to the mounting device such that the roller is rotatable in a first direction and a second direction opposite the first direction; an actuation device attached to the roller, the actuation device configured to move the roller to rotate the roller in at least one of the first direction and the second direction; a front member comprised of window covering material, the front member having an upper portion and a lower portion, the upper portion of the front member attached to the mounting device, the front member moveable from a retracted position to an extended position; a second member comprised of window covering material, the second member having an upper portion, a bottom portion, a first side and a second side opposite the first side; the upper portion of the second member attached to the roller such that rotation of the roller in the first direction winds the second member about the roller to retract the second member and rotation of the roller in the second direction unwinds the second member from the roller to extend the second member, the bottom portion of the second member attached to the bottom portion of the front member; and a plurality of generally U-shaped members, each U-shaped member having a first end portion, a second end portion, and a middle portion between the first end portion and the second end portion, the first end portion of each U-shaped member engaging or positioned within the front member, the second end portion of each U-shaped member extending from the middle portion to the second member to engage the second side of the second member; each U-shaped member being positioned such that each U-shaped member is substantially parallel to other U-shaped members; and the second end portions of the U-shaped members being sized and configured to cause the front member to form substantially parallel folds when the second member is wound about the roller to retract the front member to the retracted position.
