Pneumatic shade

A pneumatic shade comprising:

• a plurality of first slats, each first slat being elongated and including and spanning laterally between opposite longitudinal edges;
• a plurality of first fold members being elongated and co-extending longitudinally with the plurality of first slats, wherein each first fold member is attached to longitudinal edges of respective adjacent first slats of the plurality of first slats;
• and
• a plurality of second fold members being elongated and co-extending longitudinally with the plurality of first slats, wherein each second fold member is attached to longitudinal edges of respective adjacent first slats of the plurality of first slats, and are alternatingly orientated with respect to the plurality of first fold members such that each first slat spans laterally between a respective first fold member and second fold member, wherein each of the plurality of first fold members and the plurality of second fold members are configured to move between a folded state and an unfolded state upon application of pressurized air, and wherein each one of the plurality of first fold members or the plurality of second fold members are inflatable;
• wherein each one of the plurality of first fold members or the plurality of second fold members that are inflatable each include outer and inner membranes defining an air chamber;
• wherein at least one of the outer and inner membranes are resiliently flexible and configured to exert a force arranged to bias the plurality of first fold members or the plurality of second fold members that are inflatable toward the folded state;
• wherein a cross-section of each inner membrane is substantially circular when the first and second fold members are in the folded state.
