Abstract: The cushion according to the invention is made up of several layers of pneumatic elements (3) which each form a matrix (2). These pneumatic elements (3) each have a multiplicity of holes (5a) into which elastic spring elements, for example foam cylinders (1), are inserted. The pneumatic elements (3) are all substantially congruent, such that the holes (5a) of superposed pneumatic elements (3) are in each case located at the same places. An individual pneumatic element (3) is produced from two superposed sheets of an elastic plastic. The two sheets are welded sealingly to each other at the edges of the cushion and at the edges of the holes (5a). The holes (5a) are cut out after the welding. Each pneumatic element (3) has at least one connection for compressed gas. While supporting a patient, the pneumatic elements (3) are alternately supplied with compressed gas and then relaxed again.

Abstract: A pneumatic lordosis support (1) consists of a cushion (3), which is integrated into the backrest (2) of a seat. Laterally of a vertical center line (7), the cushion encompasses horizontal connections (8) between a front side and a rear side of the cushion (3). The cushion (3) is composed of an air-tight flexible membrane. In the region of the vertical center line (7), the connections (8) encompass breaks. Vertically offset to the connections (8), the cushion (3) encompasses further central horizontal connections (10), which extend substantially across the region of the breaks in the connection (8). In the region where connections (8) and central connections (10) are located close to one another, reduced radii of the membrane lead to the occurrence of less stress than in the remaining cushions (3) and allow the spine of a user to dip into the cushion (3) more softly.

Abstract: 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 ? and ? of the width thereof. The pneumatic cushions can be impinged upon with pressure and can be evacuated individually by means of a control.

In the region where connections (8) and central connections (10) are located close to one another, reduced radii of the membrane lead to the occurrence of less stress than in the remaining cushions (3) and allow the spine of a user to dip into the cushion (3) more softly.

Abstract: 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.

Abstract: A pneumatic cushion having an inner pneumatic structure constructed from a casing and webs or a plurality of tubes. The webs produce a plurality of chambers. The inner pneumatic structure may be pressurised at a pressure p1. At least one reinforcing and stiffening means is present on or in the pneumatic structure and disposed in such a manner that the pneumatic cushion's dimensional stability is increased.

Abstract: A case having a base module, the base module being physically and fluidically connected and joined by means of an appliance module, an extension module and a closing module. The base module, the appliance module and the extension module are at least partially pneumatic and dimensionally stable in a pressurized state.
