Abstract
A chair is provided which comprises a support, a seat arranged above the support, and a seat back tiltably connected to the support behind the seat. The seat back has an upper back supporting portion and a lower waist supporting portion. The chair further comprises a mechanism for deforming the waist supporting portion forward until the seat back tilts rearward to a predetermined intermediate tilt angle but for retarding or stopping such forward deformation when the seat back tilts rearward beyond this intermediate tilt angle. The seat may be made to move rearward as the seat back tilts rearward.
