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： The chair, particularly an office chair, has a backrest articulated to a seat support by way of a rest support. A seat surface is movable synchronously with the backrest. A front region of the seat surface is connected to the seat support via a sliding guide and a rear region is connected to the seat support via a seat link. A distance from an upper pivot point, which connects the seat link to the seat surface, to the backrest is shorter than the distance from a lower pivot point, which connects the seat link to the seat support, to the backrest. The movements of the backrest and of the seat surface are synchronized by a sliding guide provided between the seat link and the rest support.

摘要： A footrest is fastened via a telescopically extendable connecting element to an office chair, in particular to an office chair having a backrest that can be tilted into a rest position. This results in an especially comfortable and ergonomic seating position, and in particular a situation in which the office chair is pushed away from the footrest when the footrest is not needed.

摘要： A chair, in particular an office chair, has a backrest that is articulated on a seat carrier via a backrest carrier, and has a seat surface that can be moved synchronously with the backrest. The front region of the seat surface is connected to the seat carrier via a sliding guide. The rear region of the seat surface is connected to the seat carrier via a seat link. A top point of rotation connects the seat link to the seat surface. A bottom point of rotation connects the seat link to the seat carrier. The distance between the top point of rotation and the backrest is smaller than the distance between the bottom point of rotation and the backrest. A sliding guide for the seat surface is provided in the backrest carrier for synchronizing the movement of the backrest and the movement of the seat surface.

摘要： The invention relates to an item of seating furniture (2), in particular an office chair, with a substantially curved supporting shell (14) which has two raised, curved, flexible curved arms (24) and a rigid central piece (16) arranged between said curved arms. Furthermore, the item of seating furniture (2) comprises a covering (30) which is clamped in the manner of a secant between the curved arms (24) of the supporting shell (14), wherein, when the covering (30) is loaded, at least one curved arm (24) is at least partially increasingly raised and/or is at least partially curved in the direction of the central piece (16).

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).
