Title
(EN) ADJUSTABLE FURNITURE MEMBER
(FR) ÉLÉMENT DE MOBILIER RÉGLABLE
Abstract
(EN)
A furniture member may include a base assembly, a seat assembly, and one or more of: a legrest assembly, a tilt mechanism, a recline actuator, a height-adjustment mechanism, a seat-depth-adjustment mechanism, and rocker springs. The legrest assembly may include a legrest platform and articulating arm assemblies. Each articulating arm assembly may include first and second link-housings and first and second control links. The tilt mechanism may move the seat assembly relative to the base assembly between upright and rearward tilt positions. The recline actuator may move a seat bottom between forward and rearward positions to cause movement of a seatback relative to the seat bottom between reclined and non-reclined positions. The height-adjustment mechanism may move the seat assembly vertically. The seat-depth-adjustment mechanism may move a backrest support member relative to a seatback frame between retracted and extended positions. The rocker springs may be mounted to the seat assembly.

L'invention concerne un élément de mobilier qui peut comprendre un ensemble base, un ensemble siège et un ou plusieurs éléments parmi : un ensemble repose-jambes, un mécanisme d'inclinaison, un actionneur d'inclinaison, un mécanisme de réglage de hauteur, un mécanisme de réglage de profondeur de siège et des ressorts de basculement. Le repose-jambes peut comprendre une plate-forme de repose-jambes et des ensembles de bras d'articulation. Chaque ensemble de bras d'articulation peut comprendre des premier et deuxième boîtiers de liaison et des premier et deuxième liens de commande. Le mécanisme d'inclinaison peut déplacer l'ensemble siège par rapport à l'ensemble base entre des positions d'inclinaison verticale et arrière. L'actionneur d'inclinaison peut déplacer un fond de siège entre des positions avant et arrière pour provoquer le mouvement d'un dossier par rapport au fond de siège entre des positions inclinées et non inclinées. Le mécanisme de réglage de hauteur peut déplacer verticalement l'ensemble siège. Le mécanisme de réglage de profondeur de siège peut déplacer un élément support de dossier par rapport à un cadre de dossier entre des positions rétractée et étendue. Les ressorts de basculement peuvent être fixés à l'ensemble siège.
