LIFTING SYSTEM FOR ADJUSTABLE HOSPITAL BED ABSTRACT OF THE DISCLOSURE Independently operable lifting mechanisms are provided at the head and foot ends of the fixed lower base frame of an adjustable hospital bed in order to facilitate independent height adjustment of the head and foot ends of the bed's movable upper frame. The two lifting mechanisms are actuated by respective ones of two drive screws which may be rotated individually or simultaneously and in either direction to position the upper frame at any desired height and at any selected tilt angle. In other words, by turning only one of the drive screws one end of the upper frame is elevated or lowered and the tilt angle will be changed. By rotating both of the drive screws at the same time the upper frame will be raised or lowered at a constant tilt angle. This flexibility enhances the medical treatment that a hospital patient may receive.
