Abstract

Bei einem Funktionsstuhl ist ein Sitzteil (20) über ein gummielastisches Material (38) umfassendes Gelenk (18) mit einem Kopfteil (16) des Fußgestelles (10) verbunden, so daß es bezüglich des Kopfteiles (16) entgegen Federkraft verkippbar ist. Ähnlich ist ein Lehnenteil (28) über ein Gelenk (26) mit einem Lehnenträger (24) verbunden, der ein Verkippen des Lehnenteiles (28) bezüglich des Lehnenträgers (24) um eine horizontale Achse und um eine zur Lehnenlängsrichtung parallele Achse gestattet.

Figure 00000001
In the case of a functional chair, a seat part (20) is connected to a head part (16) of the base frame (10) via a joint (18) comprising a rubber-elastic material (38), so that it can be tilted against spring force with respect to the head part (16). Similarly, a backrest part (28) is connected via a joint (26) to a backrest support (24), which allows the backrest part (28) to be tilted with respect to the backrest support (24) about a horizontal axis and about an axis parallel to the backrest longitudinal direction.
