The invention relates to a chair, especially an office or work chair or similar, whereon a back-rest part ( 15 ) can be placed in an inclined position from an initial or rest position via a first axis of rotation ( 12 ). A seating part ( 14 ) performs a longitudinal displacement around a second axis of rotation ( 20 ) and an inclined displacement around a third axis of rotation ( 11 ) in a synchronous manner with respect to the inclined movement of the back-rest part ( 15 ). A return device ( 13 ) is provided for returning the back-rest part ( 15 ) and/or seating part ( 14 ) to the initial position or rest position. The office chair ( 1 ) comprises a carrier frame ( 5 ) which disposed centrically on the leg frame ( 2 ) and which supports in a stationary manner the first axis of rotation ( 12 ) on the centre of the leg frame, said axis of rotation remaining at a constant, predetermined distance above the seating part ( 14 ) in the rest position and in all inclined positions of the back-rest part ( 15 ). Said first axis of rotation ( 12 ) is connected in a secure manner to the back-rest part ( 15 ) by means of a pivoting lever ( 16 ). |
