    Abstract: An inflatable structure includes a top end cap, a bottom end cap, a bladder attached to the top and bottom end caps and configured to hold pressurized air, a plurality of tethers disposed within the bladder, the inflatable structure moveable between a stowed profile and a final support profile, wherein the bladder is pressurized and expanded axially and the plurality of tethers are fully extended and restrict further movement of the top end cap and the bottom end cap away from one another and limit axial expansion of the bladder, a pulley assembly mounted within the bottom end cap, wherein in the stowed support profile, the plurality of tethers are wound onto the pulley assembly, the pulley assembly adapted to allow selective extension of the tethers allowing axial expansion of the bladder, wherein, the inflatable structure is adapted to provide multiple intermediary support profiles capable of supporting compressive loading.

    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.

    Abstract: A selectively rigidizable membrane for cargo management comprises a vacuum bladder, and a first architectural layer and a second architectural layer, each of the first and second architectural layers including a plurality of tiles interconnected by flexural elements, each of the tiles of the first and second architectural layers including at least one constraining element extending therefrom, wherein, when atmospheric pressure is present within the vacuum bladder, the first and second architectural layers are slidably moveable relative to one another and the membrane is flexible, and further wherein, when negative pressure is applied to the vacuum bladder, the first and second architectural layers are forced into engagement with one another, the constraining elements of the first and second architectural layers providing mechanical interference and preventing sliding movement of the first and second architectural layers relative to one another, causing the membrane to become substantially rigid.

    Abstract: Cargo systems are provided for vehicles that include, in one embodiment: a variable cargo surface disposed within a body of the vehicle behind one or more occupant seats, the variable cargo surface including: a low friction surface that facilitates movement of cargo within the cargo system, the low friction surface having a first coefficient of friction; a high friction surface that inhibits movement of cargo within the cargo system, the high friction surface having a second coefficient of friction that is greater than the first coefficient of friction; and a control device that selectively activates the low friction surface and the high friction surface based on conditions for the vehicle; wherein the low friction surface contacts the cargo within the cargo system when the low friction surface is activated; and the high friction surface contacts the cargo within the cargo system when the high friction surface is activated.
