Abstract
A hospital bed has a base and a patient support mounted on the base, the patient support including a head panel that pivots between a horizontal position and an upwardly-inclined position to raise the patient to a sitting attitude. The head panel is connected to a ball nut mounted on a screw driven by a motor to raise and lower the head panel. The ball nut has a ratcheting latch that enables the head panel to be lifted manually and prevents the head panel from being driven positively downwardly in such a way as to injure some thing or person in its path.
