Abstract

La présente invention a trait à un siège de type fixe, dont le dossier ne s'incline pas, qui peut prendre une orientation normale et une orientation de repos (correspondant à une orientation inclinée normale). Un mécanisme de support de matériau de coussin qui supporte un matériau de coussin de siège (400) est prévu sur un cadre de coussin. Ledit mécanisme de support de matériau de coussin est doté d'un cadre coulissant (310) qui est pourvu de trous de guidage allongés (311 et 312) définis de manière à ce que le cadre coulissant puisse coulisser diagonalement vers le haut/vers l'arrière et vers le bas/vers l'avant avec le matériau de coussin de siège (400) supporté. Dans la mesure où le cadre coulissant coulisse diagonalement vers le bas/vers l'avant, bien que l'inclinaison du siège ne change pas, le matériau de coussin de siège (400) se déplace vers l'avant, ce qui permet à l'angle torse de la personne assise sur le siège d'augmenter, ce qui a pour résultat effectif l'obtention d'une posture similaire à celle qui résulte de l'inclinaison du dossier d'un siège classique.
