Abstract

Improvements introduced in adjustable seat and back chairs, with a device for the tilt without backrest steps and with another device to raise and lower the seat of the chair by means of a gas cartridge actuated by a tilting lever, having the device of tilting of the backrest a leaf spring connected at one end to the backrest and which is subjected to the effect of a tension spring and can be immobilized by means of a clamping device, releasing the force of the tension spring when releasing the clamping and making the leaf spring that the backrest tilts forward, and the clamping device is constituted by an eccentric and a corresponding stop and the eccentric can be actuated by means of a hollow lever, characterized in that one end (14a) of the lever overlaps the shaft (8) of the eccentric and serves as a support for the rocker lever (15), and because this extre m or (14a) of the lever is connected to the axis (8) of the eccentric through a coupling that, when tilting the lever (14) in one direction, draws with it the axis (8) of the eccentric, while at the Tilting in the opposite direction releases this force lock joint.
