An adjustable chair frame with a back and seating surfaces that flex to conform to the shape, weight and movement of an occupant is disclosed. The chair form and proportions provide for a recumbent position that disperses the weight of the occupant more evenly, thereby reducing external and internal physiological point loading. The form also provides ergonomic articulation to minimize internal physiological stresses such as neck/back vertebral compression. Eccentric connections driven by a motor assembly allow positioning adjustment of the components of the chair. Additionally, an air pump assembly may be included to automatically adjust one or more air bladders provided on the interior of the chair frame.

A toting apparatus can include a bucket, a combination lid and seat cushion, and a harness for carrying the apparatus while the lid covers the top opening of the bucket and the cushion is in the inflated or deflated configuration. The cushion can be formed by a drop-stitch type bladder inflatable using a common hand-operated bicycle pump. The harness can include a belt that wraps around the bucket and a pair or diametrically spaced-apart straps that adjustably and snuggly attach to a central handle structure atop the lid. Various corresponding patches of hook-and-vane style fabric fasteners allow for releasable affixation of various components of the apparatus. Thus the harness can be made of durable flexible fabric.

A structure that includes strut tubes that receive and hold within them a granular material—soil, sand, gravel, regolith, or plastic pellets—to which compression is applied after loading. By this means the struts are stiffened to facilitate its use as a durable shelter. The structure is erected by inflating the strut tubes with a fluid which is then displaced with the granular material before compression is applied.

An adjustable seat system for use with a vehicle, with the system including a cushion associated with a passenger seat of the vehicle. The cushion includes a support structure and a bladder encapsulating the support structure, wherein the support structure is formed from a porous foam material. The system also includes an actuator in communication with the bladder, wherein the actuator is configured to selectively adjust the hardness of the cushion by inflating and deflating the bladder.

Device (10, 110, 210) including at least one flexible pouch (12, 21, 22) delimiting an interior volume, one air inlet opening (13) per flexible pouch to allow air to pass into an interior volume of the pouch, a closure for closing the air inlet in an airtight manner, the closure including two flexible strips (14, 16) located at the periphery of the air inlet opening, the strips being connected at their ends and adapted to be pressed against one another. A rigid movable part (24, 25, 26) is pivotally connected to one of the ends of the strips so that the movable part can be positioned around the strips in a closed position in which the two strips are kept clamped together so as to prevent air from escaping the device.

A seat assembly includes a cushioned component having a lattice matrix, wherein the lattice matrix includes a first portion defined by a first pattern of interconnected links which defines a first set of cells, and a second portion defined by a second pattern of interconnected links which defines a second set of cells. The first portion of the lattice matrix includes a density profile that is different than a density profile of the second portion of the lattice matrix. An air bladder is disposed within a core portion of the lattice matrix and includes a non-porous outer casing surrounding an interior cavity. The outer casing of the air bladder and the lattice matrix are integrated components comprised of a common material to define a monolithic structure created using an additive manufacturing process.

The present disclosure relates to an inflatable structure transformable between a deflated state and an inflated state, the inflatable structure comprising a drop stitch fabric having a first layer and a second layer tethered by drop stitches. At least one layer of the first and second layers comprises a ridge formed by a folded portion of the one layer, secured by a fixation line. The disclosure also relates to a manufacturing method of an inflatable structure in accordance with the foregoing, and an inflatable seat comprising such an inflatable structure.
