Abstract

Bei einem Arbeitsstuhl, beispielsweise Bürostuhl, bei dem die Sitzplatte und unabhänging davon der Rückenleh­ nenträger in der Neigung verstellbar ist, liegt die Schwenk­ achse zwischen dem Sitzträger und der Sitzplatte für die Neigungsverstellung der Sitzplatte in Nähe des vorderen Endes der Sitzplatte, und die Gasfeder für die Neigungsver­ stellung der Sitzplatte greift im hinteren Bereich der Sitz­ platte an dieser an. Vorteilhaft ist die Arretierung der Gas­ druckfeder für die Neigungsverstellung der Sitzplatte auf die Dauer ausschaltbar, so daß die Sitzplatte dann etwa um ihre Vorderkante frei pendeln kann. For a work chair, for example an office chair, at which the seat plate and regardless of the backrest tilt is adjustable, the swivel lies axis between the seat support and the seat plate for the Tilt adjustment of the seat near the front End of the seat plate, and the gas spring for the inclination ver position of the seat plate engages in the rear area of the seat plate on this. The locking of the gas is advantageous compression spring for the inclination adjustment of the seat plate the duration can be switched off, so that the seat plate then around their front edge can swing freely.
