Abstract

L'invention concerne un cadre intégré profilé pour maille pour une chaise de bureau comprenant un tissu maillé (1), un cadre intérieur (2) et un cadre extérieur (3), et doté aussi d'une bande latérale de compression de maille (4) correspondant à la surface supérieure du cadre intérieur (2). Plusieurs tiges en saillie (5) sont placées de façon équidistante sur la surface supérieure du cadre intérieur (2). Les parties périphériques du tissu maillé (1) sont placées sur le cadre intérieur (2) grâce aux perforations de la maille (6) correspondant aux tiges en saillie (5) du cadre intérieur (2). La bande latérale de compression de maille (4) est pressée sur le tissu maillé (1) grâce à des trous traversants (7) correspondant aux tiges en saillie (5) du cadre intérieur (2). D'autres parties du cadre intérieur (2) et de la bande latérale de compression de maille (4) sont placées dans le cadre extérieur (3), excepté leurs extrémités intérieures laissées hors du cadre extérieur (3), et leurs surfaces extérieures sont totalement en contact avec le cadre extérieur (3). Le tissu maillé de l'application, doté d'une élasticité uniforme et d'un bon facteur d'intensité de contrainte, est solide et fiable lors de l'utilisation.
