Abstract

La présente invention concerne un siège, de préférence un siège pour passager, notamment un siège pour passager de vol, comprenant une carcasse de siège (12) pouvant être dressée sur un sol et des composants de siège montés sur la carcasse de siège (12) pour former respectivement une place assise, tels qu'un dossier (1) et une partie d'assise (2) présentant une zone avant (3) et une zone arrière (4) au niveau du passage au dossier (1) qui peut passer d'une position droite à une position inclinée et inversement, l'inclinaison de la partie d'assise (2) s'ajustant conjointement. La zone avant (3) de la partie d'assise (2) conserve alors sensiblement la même hauteur par rapport au sol et la zone arrière (4) s'abaisse au fur et à mesure que le dossier (1) s'incline. L'objectif de la présente invention est de maintenir un abaissement important de la zone arrière de la partie de siège même lorsque le dossier est un peu redressé, la zone avant de la partie d'assise gardant sa place. A cette fin, le dossier (1) est constitué d'au moins une première partie de dossier (5) et d'une autre partie de dossier (6) qui sont au moins partiellement en contact l'une avec l'autre avec leurs surfaces adjacentes l'une à l'autre et qui peuvent être réglées l'une par rapport à l'autre lors du réglage de l'inclinaison du dossier (1) de façon que l'inclinaison de la partie d'assise (2) se règle automatiquement.
