ABSTRACT:
A chair comprises a seat support with a front seat support part and a rear seat support part which is connected thereto via a pivoting axis. An adjustable length energy storing device serves for adjustment relative to each other of the seat support parts. The energy storing device is pivotably supported on the seat support parts at a distance from the pivoting axis. This distance can be modified by means of an adjusting element by operation of a turning handle. The turning handle is connected to the adjusting element via a coupling element, with the axes of rotation of the adjusting element and turning handle not being in alignment. This ensures conveniently accessible modification of the adjusting force of the energy storing device.
