Improvements in the means of articulation for backs of beds, essentially characterized by comprising a rod (1), displaceable in its axial sense, thanks to an electric motor that drives gears located in a cylinder and whose rod is hinged at its end, on the intermediate shaft (2), articulated between the two braces (3), articulated at their upper end, on the shaft (4), supported between the two fixed bars (5), of the fixed part of the bed frame and whose braces (3), act as a rocker of its lower axis (6), in which the bar (7), which crosses a rectangular box (8), without a bottom, from whose opening a rectangular plate protrudes vertically (9) is articulated (9), which has a hole (10), adjusted to the bar (7); to comprise a pin (14), which passes through the box, parallel to the rectangular plate (9), and at the ends protruding from the pin, are articulated two parallel braces (17), whose opposite ends are joined to the single crossbar ( 18), of the articulated backrest; by comprising another pin (15), inside the rectangular box (8), crossed above the bar (7), which passes through the box and in contact with the rectangular plate (9); by comprising a strut (19), traversed by the bar (7), at its exit from the box and whose opposite end is articulated on the fixed axis (20).
