PROBLEM TO BE SOLVED: To provide a chair of a type including a synchro mechanism and exerting further high comfort.SOLUTION: A shoulder region 10 is connected to a back-face support 6 in an inclinable manner about a shoulder axis A3 and is hinged to the lower back-face region 12 in a lumbar spine region 20 so as to favorably support a body and ensure adaptation to the shape of the body by inclination of a backrest 8. The lower back-face region 12 is further guided on a chair element, in particular a seat 4, such that a change of the angular orientation of the shoulder region 10 relative to the lower back-face region 14 is allowed while the shoulder region 10 is inclined about the shoulder axis A3. Complementary lateral regions are expediently designed with an orientation which is forcibly changed while the shoulder region 10 is inclined.SELECTED DRAWING: Figure 3 |
