The upholstered furniture headrest lifting mechanism is provided an electric motor and consists of an top bracket (3) in the shape of the letter "C" having two tabs (5), each with an opening (6). At the ends of the top bracket (3) there are lower tabs (11) perpendicular to it and pointing downwards. The motor (4) is attached to the top bracket (3), which in its lower part is attached to a punched bracket (7), wherein at one end of the top bracket (3) a tie-rod (1) is attached together with its movable extension (25). The longer arm (22) of the extension (25) has a right-angle bent surface (23) to which support flat bar (29) is attached and the longer arm (22) of the extension (25) is connected to the tie-rod (1) using a friction or ratchet joint (21). The tie-rod (1) is fixed axially to top bracket (3), while to one lower tab (11) of the top bracket (3) a sliding slider (12) is fixed, which has fixing holes (13) and a pin (15), on which a plastic profiled slider (14) is fixed in pivotable and non-moving manner, placed in the guide (17). At the other end of the top bracket (3) an analogous movable extension (25) is fixed via a tie-rod (1) and a sliding slider (12) in a mirror-image surrounding guide (17).
