摘要:
A sitting and reclining cushion is divided into a seat cushion and a back cushion, which are configured in an essentially identical manner. A sleeve consisting of a textile material with low elasticity contains a plurality of tubular pockets consisting of an identical material and joined longitudinally to said sleeve by means of seams. Each pocket is likewise connected to its neighbour or neighbours by means of seams. Each pocket contains a pouch, which consists of an elastic plastic and comprises a valve, and can be filled with compressed air. As a result, the pockets modify their shape, thus tensioning the sleeve and forming the actual sitting or reclining surface. The optimised shape of the cushion structure can be adapted to individual requirements for comfort by means of different air pressures in the pouches.

The pneumatic actuator of the invention is constructed from a plate (1) that is for example level and is secured in a reference system (9). On the one side of the plate (1), a first web (2) of a highly resistant and poorly extensible woven textile is secured such as by gluing alongside several strips (3). A second web (4), which is preferably made from the same material, is applied to the first web (2) and connected to the first web (2) along the strips (3). Between the strips (3), bladders (7) made of an elastic plastic material are inserted in the loose portions of the first and the second web (2, 4), said bladders being closed on both sides and comprising one valve (8) each. The bladders (7) can be pressurized with compressed gas through said valves (8). This causes the second web (4) to arch, the thus generated forces effecting onto the plate (1) a bending moment that causes the latter to laterally bend away.

A pneumatic actuator having a flexible plate, the flexible plate being made of a rigid flexible material. The pneumatic actuator further includes at least two elongate, flexible but poorly extensible pneumatic pressure ducts that are disposed side by side and are in parts connected to the flexible plate to which they are secured and on which they are arranged in such a manner that, when the pressure ducts are pressurized with compressed gas, tangential forces are generated parallel to the flexible plate causing said flexible plate to bend.
摘要:
A pneumatic cushion for use as a sitting, lying and reclining cushion. The cushion includes a casing made from limited-extensibility material. The casing includes a plurality of webs made from limited-extensibility material, the plurality of webs are adapted to divide a cross-section of the pneumatic cushion into a plurality of chambers and positively connect opposite sides of the casing to each other thereby limiting the cushion's maximum spread at web level. A plurality of gas-tight bladders capable of being pressurized with a pressure fluid are inserted in each of the plurality of chambers created by the plurality of webs and the casing.
摘要:
The inventive cushions (5) for sitting, leaning or lying upon are essentially constructed of a pneumatic structure and of a covering that surrounds the pneumatic structure. The pneumatic structure consists of an enclosure (2) and webs (3) resulting in the formation of chambers (4). The pneumatic structure is pressurized whereby tensioning the covering so that the ribbed surface of the pneumatic structure can no longer be clearly perceived. In other embodiments, the cushions (5) are equipped with means for individual adaptation. They can also be supplemented with reinforcing and stiffening structures. Cushions (5) can be deformed or moved relative to one another by means of pneumatic actuators.
摘要:
The invention comprises a structure having at least two separate air chambers (7) enclosed by flexible, flat material (8) and having flexible bars (9) in the interior thereof for stabilizing an external shape of the air chambers (7). The structure is characterized in that the air chambers (7) form a wall structure (4) in the inflated state. By means of such a wall structure (4)—preferably in conjunction with a corresponding ceiling structure (16)—lightweight berths (1), particularly for aircraft crew, flight passengers, or transported injured persons, can be set up quickly and simply.

The invention relates to a backseat with a base plate (1) and a corresponding back plate (11) on which one layer (2) ON of foam each or pneumatic cushions covering both plates (1, 11) are arranged. Following pneumatic cushions are placed on said layer (2) and are suitably secured thereto: For every passenger occupying a window seat, one edge cushion (13) each, resting towards outside and towards inside, and one lateral cushion (4, 14) each, resting towards inside, is provided, the latter being impinged upon with tensile forces by tension elements (9, 19) inserted in a tube (8) for the rapid evacuation of air. In the center of the backseat, a planar cushion (5, 15) is located and may also serve as a center shelf. The back plate (11) may be subdivided into two back plates (11a, b) which occupy approximately ⅓ and ⅔ of the width thereof. The pneumatic cushions can be impinged upon with pressure and can be evacuated individually by means of a control. Once the air is evacuated from the cushions, the back plate (11a, b) can be folded onto the base plate (1) entirely or partially.
摘要:
A pneumatic structure for sitting, lying and reclining cushions including a plurality of cells disposed together in rows and frictionally interconnected at a plurality of sides along a transversal web thereby forming a layer, the layer being charged with compressed gas through at least one valve and made from a membrane of flexible, gas-tight material. The structure displays a plurality of frictionally interconnected layers, the layers being interconnected such that a longitudinal web separating the layers is present. A casing made from flexible, elastic material is present and envelops the plurality of layers. The casing is frictionally connected partly or across a full length of a contact line to at least one cell.
