Abstract
An adjusting mechanism for an adjustable chair includes a control mechanism, by means of which a control push rod of a spring mechanism is adjusted from a locking position to an unlocking position. In the unlocking position, the chair frame which comprises a seat carrier, a back rest carrier and a pedestal constituted by a pillar and a support part, can undergo a positional adjustment. The locking and unlocking positions are set with a single handle of an operating member which effects a displacement of two control bolts provided with meshing tooth systems, which makes the adjusting mechanism simpler and more advantageous to use.
