Abstract

A pneumatic shade includes a plurality of slats, a plurality of first fold members, and a plurality of second fold members. Each slat is elongated and includes and spans laterally between opposite longitudinal edges. Each of the first- and second-fold members are elongated and co-extend longitudinally with the slats. Each first fold member is attached to longitudinal edges of the respective adjacent slats. Each second fold member is attached to longitudinal edges of respective adjacent slats and are alternatingly orientated with respect to the first fold members such that each slat spans laterally between a respective first fold member and second fold member. Each of the first fold members and the second fold members are adapted to move between a folded state and an unfolded state upon application of pressurized air.
