The work chair has a seat squab and a backrest which both pivot on a seat carrier in the same direction interdependently. A load element is fitted to the seat carrier which is adjustable over its linear extension by means of a locking mechanism, whereby the load element pivots the seat squab and backrest into position of rest under spring loading. To achieve a relatively large and symmetric spring loading in the smallest space it is foreseen that the load element should consist of two parallel compression springs in between which a hydraulic locking mechanism is fitted whereby one end of the load element is connected by a pivot to the free pivoting part of a lever arm, which forms the backrest-carrying part. |
