Abstract (en)
[origin: WO2013164078A1] The chair has a seat (4), which is fixed to a base support unit (2), and a backrest (8), which has a lower backrest region (12) and an upper shoulder region (10) and which is fixed to a backrest support (6). The backrest support (6) is rotatably mounted on the base support unit (2) about an inclination axis (A1). The aim of the invention is to ensure an improved guiding and adaptation to the shape of the body in particular while the backrest (8) is inclined. This is achieved in that the shoulder region (10) is connected to the backrest support (6) in an inclinable manner about a shoulder axis (A3) and is hinged to the lower backrest region (12) in a lordosis region (20). The lower backrest region (12) is further guided on a chair element, in particular the seat (6), such that a change of the angular orientation of the shoulder region (10) relative to the lower backrest region (14) is allowed while the shoulder region (10) is inclined about the shoulder axis (A3). Complementary lateral regions (18) are expediently designed with an orientation which is likewise changed in a positively guided manner while the shoulder region (10) is inclined.
