The present invention relates to an arrangement in a chair (1), especially a recline chair having an adjustable chair back (2) and a neck support (3), and is especially characterized in that the arrangement comprises means (12, 15) which influence the shape of the chair back (2), especially in the area (6) proving support for the user's lower back, and then in dependence of the inclination of the chair back (2). Especially, the invention provides a pronounced support for the user's lower back when the chair back (2) is in an erected sitting position, whereas said means (12, 15) render a gradually decreasing support of the user's lower back when said chair back (2) is lowered rearwardly towards a lying position. The lumbar region support (6) co-operates with a system for regulating the neck support (3) and the return thereof to a normal position each time the chair back (2) arrives at an extreme upper or lower position.

Cette invention concerne un mécanisme d'une chaise (1), en particulier d'une chaise à dossier inclinable (2) et à appui-nuque (3), ayant en particulier pour fonction, grâce à un moyen (12, 15) de modifier la forme du dossier (2) principalement dans la région d'appui lombaire et selon son degré d'inclinaison. Plus précisément, l'invention offre un appui solide à la région lombaire de l'utilisateur lorsque le dossier (2) est en position relevée et, grâce au moyen (12, 15), elle réduit progressivement cet appui lombaire à mesure le dossier (2) est abaissé. L'appui lombaire (6) est interconnecté avec un mécanisme de réglage de l'appui-nuque (3) qui assure le rappel de celui-ci à sa position initiale au point mort bas ou haut du dossier (2).
