Abstract
The chair has a sub frame (1) set on the floor, a mechanism (2) set on the sub frame, a seat (3) set on the mechanism (2) and a backrest (7) attached to the mechanism (2). The backrest (7) exhibits a backrest frame (5), which supports an elastically deformable backrest part (6) with a back panel (62). The back panel (62) has a back part (60), to which a head restraint (61) is attached. The backrest (7) is capable of pivoting about a first pivot shaft (D1) from an essentially upright, neutral position to a reclined position displaced towards the rear. The movements of the seat (3) and the backrest (7) are synchronized with one another. In the event of the elastic deformation of the back part (60) into a free space for the backrest frame (5), by the application of a force in the direction of the reclined position having an essentially concave tendency to the back of the user, means (53,67,D4;55,610,D5) are provided for an opposing raising of the shoulder area, as a transitional zone of the back part (60) for the head restraint (61), and of the head restraint (61).
