Abstract

An office chair includes a seat portion pivotable about one horizontal axis relative to a vertical stand and a back rest portion pivotable about another horizontal axis relative to the vertical stand of the chair, upon the application of the weight of the seated person onto the seat portion. The seat portion and the back rest portion are coupled to each other by a coupling lever and a holding element for holding the back rest portion so that when the seat portion is inclined forwardly the back rest portion is also inclined forwardly and when the seat portion is inclined rearwardly the back rest portion follows this motion of the seat portion.
