The inventive sitting and reclining cushion is divided into a seat cushion and a back cushion, which are configured in an essentially identical manner. A sleeve (4) consisting of a textile material with low elasticity contains a plurality of tubular pockets (5) consisting of an identical material and joined longitudinally to said sleeve by means of seams (6). Each pocket (5) is likewise connected to its neighbour or neighbours by means of seams (6). Each pocket (5) contains a pouch (7), which consists of an elastic plastic and comprises a valve (8), and can be filled with compressed air. As a result, the pockets (5) modify their shape, thus tensioning the sleeve (4) 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 (7).
La présente invention concerne un coussin d'assise et de dossier qui se compose d'un coussin d'assise et d'un coussin de dossier qui ont une structure fondamentale identique. Dans une enveloppe (4) faite d'une matière textile à dilatation faible se trouvent une pluralité de poches tubulaires (5) qui sont faites d'une matière identique et sont reliées à ladite enveloppe, le long de celle-ci, par des cordons (6). Chaque poche (5) est reliée à la/aux poche(s) voisine(s) également par des cordons (6). Chaque poche (5) contient une poche interne (7) en matière plastique extensible qui comprend un clapet (8) et peut être soumise à de l'air pressurisé, sous l'effet duquel les poches (5) se déforment et tendent l'enveloppe (4) qui prend ainsi la forme propre de la surface d'assise ou de dossier. La forme structurelle optimale des coussins peut être adaptée au confort personnel souhaité grâce à l'application de pressions différentes dans les poches internes (7).
