Covering for architectural features, and related systems, methods of operation, and manufacture

A covering for an architectural feature having a width and a height, the covering for adjusting the amount of light that passes there through and comprising:

• a flexible panel having a width, a top end and a bottom end defining a height of the panel, the panel comprising:
• a flexible first vertical support member having a height;
• a flexible second vertical support member having a height;
• and
• a plurality of horizontally-extending, flexible vanes extending between the flexible first vertical support member and the flexible second vertical support member, the plurality of flexible vanes being separately formed from and spaced along the height of the flexible first vertical support member and along the height of the flexible second vertical support member, each of the plurality of flexible vanes having a length and a width, the length of the plurality of flexible vanes corresponding to and substantially the same as the width of the panel, each of the plurality of flexible vanes operably coupled to both the flexible first vertical support member and the flexible second vertical support member, the plurality of flexible vanes moveable, by operation of at least one of the flexible first vertical support member and the flexible second vertical support member, between a first position that permits light to pass through the flexible panel and a second position that inhibits light from passing through the flexible panel;
• wherein each of the plurality of the flexible vanes has a different light transmissivity than at least one of the flexible first vertical support member and the flexible second vertical support member;
• wherein at least one of the plurality of flexible vanes forms a cellular vane wherein the cellular vane is formed from a single sheet of material that has two end portions that are connected by ultrasonic welding to form two layers that are separable to form and surround a cell space when the cellular vane moves to the first position;
• wherein an outer surface of a first layer of the two layers is adhesively bonded directly to the flexible first vertical support member and an outer surface of a second layer of the two layers is adhesively bonded directly to the flexible second vertical support member;
• and
• wherein longitudinal edges of the two end portions of the single sheet of material forming the cellular vane are aligned and are connected by ultrasonic welding to form a first fold line.
