Abstract

Mechanism for varying the inclination of the backrests in different seats, characterized in that the mechanism, located at the confluence of the backrest and the seat, is constituted by a wheel provided with a toothed sector, rotating on a transverse axis, with whose teeth corresponds a ratchet, with an axis located slightly below that of the wheel, and in which also rotates an obtuse angle lever, which at its other end is articulated to a second angular lever, which below the angle, has its axis mounted on the cogwheel; the other end of this second lever leaning at a right angle, upwards with the end of which acts on a part that pushes the anatomical profile of the back of the chair, on the part of the user's lumbar region, whose pusher is part of a lever, which has its axis of rotation inside the upper part of the backrest.
