US Patent 9157272 Cellular shade having at least two cellular columns

An expandable and contractable shade assembly includes at least a first column of cell structures aligned vertically one above another and a second column of cell structures also aligned vertically one above the other. The second column of cell structures can be positioned offset and nested with the first cell structures such that each second cell structure may be positioned in between two adjacent of the first cell structures. One or more lift cords may be encased or contained within the first cell structures. The first cell structures not only have lift cords but also provide the product with added integrity.
