a bed positioning mechanism is disclosed a bed positioning mechanism which comprises height adjustable elevators (1, 2, 3) which are mounted on structural frame (4) and connected to the patient surface frame (5). the first elevator (1) is arranged such that its axis intersects a longitudinal axis (6) of the frame (5) and said elevator (1) is connected to the frame (5) both in an oscillating manner about the longitudinal axis. (6) of the frame (5), as well as slidingly towards the longitudinal axis (6) of such frame. the second elevator (2) and the third elevator (2) are interconnected with an arm (10) oriented transversely to the longitudinal axis (6). such an arm is connected to the frame (5) in an oscillating manner, while it is connected at one end to the second elevator (2) both in an oscillating manner about an axis which is parallel to the longitudinal axis ( 6) of the patient's surface frame (5), as well as sliding transversely with respect to that frame (5). at the other end, said arm is connected to the third elevator (3), oscillating about an axis, which is parallel with the longitudinal axis (6) of the frame (5), wherein such first elevator (1) at its upper end it carries at least a first horizontal guide (7), on which a first slider (8) is slidably mounted, and said first slider (8) is connected to a fork (9) in an oscillating manner. while the fork (9) is connected to the patient's surface frame (5) in an oscillating manner, while the second elevator (2) carries at its upper end at least a second guide (12) in which at least at least one second slider (11) is slidably mounted which is connected with a pin (17) to one end of the arm (10), while the third elevator (3) is connected to the opposite end of the arm (10) with a pin (17).mecanismo de posicionamento de um leito é divulgado mecanismo de posicionamento de um leito, o qual compreende elevadores ajustáveis em altura (1, 2, 3) que são montados sobre armação estrutural (4) e conectados à armação de su
