A mechanism to center a patient on a patient support platform of a therapeutic bed is provided comprising a threaded rod that has left-hand threads on one end and right-hand threads on the other; first and second mounts threadably engaged with the left-hand and right-hand threads, respectively, of the threaded rod; and first and second patient support accessories mounted to the first and second mounts, respectively. The rod, when rotated, is operable to move the first and second patient support accessories in opposite directions, either toward or away from the patient. In one embodiment, a manually operable handle is connected to the threaded rod for effecting rotation of the threaded rod to produce symmetric movement of the first and second patient support accessories. In another embodiment, a motor-driven actuator is operably connected to the threaded rod for effecting rotation of the threaded rod to produce symmetric movement of the first and second patient support accessories. |
