Title
(EN) A SWING SUPPORT DEVICE FOR A CHAIR
(FR) DISPOSITIF DE SUPPORT OSCILLANT POUR UNE CHAISE
Abstract
(EN)
A swing support device for a chair.The swing support device comprises a frame part (310) provided with a longitudinal centre line (L3) and a first opening (330) extending in the direction of the longitudinal centre line of the frame part through the frame part. A muff (610), being at least partially resilient, is positioned in the first opening and provided with a second opening (660) extending in the direction of the longitudinal centre line of the frame part through the muff. An outer surface of the muff is provided with at least one recess (620, 630), receiving a stiff compression plate (640, 650). An actuator (500) extends into contact with the compression plate in order to either increase the stiffness of the muff or decrease the stiffness of the muff be regulating the compression force of the compression plate.

L'invention concerne un dispositif de support oscillant pour une chaise. Le dispositif de support oscillant comprend une partie de cadre (310) pourvue d'une ligne centrale longitudinale (L3) et une première ouverture (330) s'étendant dans la direction de la ligne centrale longitudinale de la partie de cadre à travers la partie de cadre. Un manchon (610), qui est au moins partiellement résilient, est positionné dans la première ouverture et pourvu d'une seconde ouverture (660) s'étendant dans la direction de la ligne centrale longitudinale de la partie de cadre à travers le manchon. Une surface extérieure du manchon est pourvue d'au moins un évidement (620, 630), recevant une plaque de compression rigide (640, 650). Un actionneur (500) s'étend en contact avec la plaque de compression afin d'augmenter la rigidité du manchon ou de diminuer la rigidité du manchon en régulant la force de compression de la plaque de compression.
