摘要： This invention concerns a chair with a seat panel, with a central column or several legs and with a backrest carrier. In order to provide a tilting movement, the front of the seat panel rests on a horizontal, crosswise running first pivot and, in order to provide a tilting movement, the rear of the seat panel is attached to the backrest carrier around a second pivot. The backrest carrier is attached to the central column or the legs around a third pivot. The springs are arranged so that they exert an upward force on the seat panel and a forward force on the backrest. An arrangement of springs is provided that has at least one gripped spring, comprising bent spring-steel rod or wire, attached to the central column or the chair legs with at least one first and one second leg of the spring. The spring is hinged to the seat panel and supports the seat panel with one or more spring sections, and, at the same time, forms the first pivot. Further, the spring rests on the seat panel and on the backrest carrier and is pre-stressed in such a way that it exerts an upward force on the seat panel and a forward force on the backrest via the backrest carrier.
