Abstract

Improved device for the inclination movement of the backrest of armchairs, in particular of office chairs; provided with a housing integral with the seat plate in which a fastener for the back-rest is mounted rotatably on a horizontal axis, characterized in that the fastener has a toothed segment meshing with a pinion fixedly mounted on an axis; that on said shaft a support body is fixedly mounted, on which two symmetrically opposed ratchets provided with external toothed flanks and rotating in a plane normal with respect to the shaft are mounted; that coaxially to the shaft is provided a non-rotating retaining ring provided with internal toothing against which the ratchets are pressed by their toothed flanks by the spring force, each ratchet blocking the rotation of the support body in that direction, in which the other ratchet leaves it free; the ratchets each have a bolt or the like for the shaft with assistance and, when a freely-mounted rotary wheel is rotated on the shaft, the ratchet which locks the support body in the respective direction of rotation is rotated by means of driving surfaces provided on the shaft. Steering wheel against the force of its spring, and that the supporting body carries a bolt or additional analog that rises with play between two other steering surfaces of the steering wheel.
