Abstract
A synchronous chair mechanism is disclosed for simultaneously changing a seat and a backrest of a chair from a zero position in which the backrest is tilted to a minimum extent relative to the seat, into an end position in which the backrest is tilted to a maximum extent relative to the seat. The synchronous chair mechanism includes a base that is connectable to a substructure provided for setting up the chair. The synchronous chair mechanism also includes a backrest carrier on which the backrest is mountable, a seat support that is designed for holding a seat, and a spring element having a front end and a rear end.
