Abstract: The patient support apparatus includes a base frame and a patient support assembly. The patient support assembly is pivotably mounted the base frame and is moved by a first actuator to rotate between a horizontal position and an upright position. The patient support assembly includes an upper body portion, a lower body portion and a leg portion. The upper body portion, the lower body portion and the leg portion are pivotably interconnected with a linkage frame so that they can be moved in unison by a second actuator between a supine configuration and an upright, chair shaped configuration. Thus, the patient support apparatus is adjustable between a flat, bed shaped configuration and a seat shaped configuration and is also movable between a horizontal position and an upright position.
