Abstract
An arrangement for the prevention of bedsores on invalids confined to bed, in which the bed can be tilted toward either side for shifting the weight distribution of a patient to promote circulation of the blood and thereby prevent the development of bedsores. A reversible motor drives a ball nut through a worm screw so that motion of the ball nut in one direction raises one side of the bed frame, and motion in an opposite direction raises the opposite side of the bed frame.
