Patent

CA 2338568

A chair has a seat (4) and a backrest (5) which are independently pivotable within limits at extremities. The seat is biassed upwardly at the front and the backrest is biassed forwardly. The seat and the backrest have a common pivot joint (8), under the centre of gravity of the occupant. There are no occupant-operated controls as the chair responds automatically to the posture of the occupant, providing full support at all relative positions of the seat and the backrest in a balanced manner for occupants of a wide range of weights.

Une chaise comprend un siège (4) et un dossier (5) lesquels pivotent indépendamment à l'intérieur de limites au niveau d'extrémités. Le siège est sollicité vers le haut, à l'avant, et le dossier est sollicité vers l'avant. Le siège et le dossier comprennent une articulation à pivot commune (8), sous le centre de gravité de l'utilisateur. Il n'existe aucune commande actionnée par l'utilisateur étant donné que la chaise réagit automatiquement à la posture de l'utilisateur, assurant un support total dans toutes les positions relatives du siège et du dossier de manière équilibrée pour les utilisateurs dans une large gamme de poids.
