Abstract

A chair, such as a conference or office chair, includes a seat support; a backrest support; a storage member formed as a force storage element; and a transmission coupling the seat support with the backrest support which allows a pivoting of the backrest support and the seat support between an upright position and a backwardly pivoted position according to a predetermined sequence of movements. The force storage element is coupled with the seat support and the backrest support such that the predetermined sequence of movements is facilitated and the storage member provides a force restoring in the upright position and wherein the flexibly elastic storage member forms in conjunction at least with a first articulated rotation point of the transmission a kinematic chain.
