摘要：
The present invention relates to an operating device for a seat, an armchair or a couch, where the angle between the base (3) and the back(4) can be modified, so that the user can move from a sitting position to a position of relaxation, merely through the action of his body. The invention provides a retractable supporting means for the small of the back comprised of a flap (10) pivoting around an axis (11) and of a support (32) with a roller (33), integral with the base, and capable of positioning the retractable supporting means for the small of the back by pivoting the flap as the displacement of hte user's body proceeds.
