Title
(EN) FORWARD SLIDING RECLINING CHAIR
(FR) CHAISE INCLINABLE À COULISSEMENT VERS L'AVANT
Abstract
(EN)
An office chair (10A) includes a seat (16) and a backrest (17) that are pivotally connected together at a pivot axis (24) such that the back¬ rest (17) can pivot with respect to the seat (16) between an upright position and a reclining position. The seat (16) is mounted on a base (13) such that the seat (16) can move with respect to a base (13), and the seat (16) includes front (18) and rear portions (19) that can pivot with respect to one another. When the backrest (17) is pivoted from the upright position to the reclining position, both of the seat (16) and the pivot axis (24) move forward with respect to said base (13), and the seat front portion (18) flexes with respect to the seat rear portion (19) such that the angle between said upward faces of said seat front portion (18) and the seat rear portion (19) increases. The backrest (17) may also include an upper portion (21) and a lower portion (22) that can pivot with respect to one another. When the backrest (17) is moved to the recline position, the angle between the forward faces of the upper (21) and lower backrest portions (22) decreases.
(FR)
L'invention concerne une chaise de bureau comprenant une assise et un dossier raccordés à pivotement au niveau d'un axe de pivotement de telle sorte que le dossier puisse pivoter par rapport à l'assise entre une position redressée et une position inclinée. L'assise est installée sur une base de façon à pouvoir bouger par rapport à celle-ci et l'assise comporte des parties avant et arrière qui peuvent pivoter l'une par rapport à l'autre. Lorsque le dossier est pivoté de la position redressée à la position inclinée, l'assise ainsi que l'axe de pivotement se déplacent vers l'avant par rapport à ladite base, et la partie avant de l'assise fléchit par rapport à la partie arrière de l'assise de telle sorte que l'angle entre les faces supérieures de la partie avant de l'assise et la partie arrière de l'assise augmente. Le dossier peut également comporter une partie supérieure et une partie inférieure qui peuvent pivoter l'une par rapport à l'autre. Lorsque le dossier est mis en position inclinée, l'angle entre les faces avant des parties supérieure et inférieure du dossier diminue.
