Abstract (en)
[origin: WO2014121941A1] The invention relates to a mechanism (1) for an office chair in which the pivoting resistance of a backrest support (5) can be changed. In order to provide a mechanism (1) for an office chair in which a small adjustment movement is sufficient in order to realize a large adjustment range of the pivoting resistance of the backrest, it is proposed that an operating element (28) which is connected to the backrest support (5) provides a supporting and/or guiding path (25) for a functional element (22), which functional element (22) effects a change in the spring tension of a spring element (16) when the backrest support (5) is pivoted.
