Abstract (en)
[origin: US2015282620A1] An office chair mechanism includes a base support for placement on a chair column, a seat support on the base support being movable relative to the base support and a backrest coupled to the seat support. Pivoting the backrest moves the seat support relative to the base support. A track element is movably connected at a base support connecting point to the base support and at a seat support connecting point to the seat support to adjust pivoting resistance of the backrest. Pivoting the backrest alters position and/or location of the track element. A spring element acting on the track element and on the seat support or on the backrest and/or a backrest support is acted upon with a movement of the seat support relative to the base support. An adjustment device alters the position of a point of action of the spring element on the track element.
