DEVICE FOR ADJUSTING THE INCLINATION OF THE BACK-REST RELATIVE TO THE SEATING PORTION IN CHAIRS IN GENERAL

摘要

A device for adjusting the inclination of the back-rest to the seating portion in chairs in general, comprising a first structural element (2) rigid with the seating portion and a second structural element (28) rigid with the back-rest and hinged to the first on a transverse axis (34), characterised in that with one of the two structural elements (2, 28) there is associated a first member (12) provided with an inclined surface (16) and rotating about an axis (14) which intersects said transverse hinging axis (34), with the other of the two structural elements (28, 2) there being associated a second member (32) maintained constantly in contact with said inclined surface (16) for any angular position of said first member (12).
