摘要： An item of seating furniture, in particular an office chair, has a seat carrier for a horizontal seat member, and a backrest carrier for a vertical backrest. The backrest carrier is constructed in a substantially U-shaped manner with two vertically orientated U-shaped members and with a horizontal upper U-shaped member. Wherein, along at least one rotation axis which extends below the seat member, a first rotary joint and a second rotary joint are provided for the lateral tilting movability of the backrest with respect to the seat carrier. The first and second rotary joints are arranged spaced apart from each other along the rotation axis.

摘要： A seat, in particular an office chair, has a synchronous mechanism with a weight-adapting mechanism. An automatic adaptation of a spring force acting on the synchronous mechanism depends on the weight momentarily exerted on the seat. Therefore, the spring force is transmitted to the synchronous mechanism via a lever whereof the active arm length of the lever can be modified to adjust the spring force. The weight-adapting mechanism is configured such that the active arm length is automatically adapted to the weight momentarily exerted on the seat.

摘要： In the case of a backrest (1), in particular for an office chair, having a lordosis support (3) comprising supporting ribs (2) arranged in a manner such that they run parallel to one another, said supporting ribs are precurved in a flexurally elastic manner in their starting position. An adjusting element (9), which can be actuated via an adjusting member (6) and is intended for setting the lordosis curvature (18), is guided on the curvature side (12) of the lordosis support (3) in such a manner that the lordosis curvature (18) decreases during a tensile loading of the adjusting element (9).
