An invalid positioning device comprising a support structure, a lifting element which is angularly displaceable about a main horizontal axis relative to the support structure, and a power operated mechanism for pivoting the lifting element about the said main horizontal axis. The power operated mechanism is arranged such that the torque applied by the power operated mechanism decreases as the lifting element moves away from one extreme position and increases again as the lifting element approaches its other extreme position and such that the angular speed of the lifting element increases as it moves away from one extreme position and decreases as it approaches its other extreme position.
