ABSTRACT:
The chair includes a movable seat and back that are configured to enhance the patient's comfort by providing lumbar support when the chair is in the recumbent position and by minimizing patient sliding within a moving chair. Chair movement is controlled by a microprocessor-based control system that includes sensing mechanisms for precisely monitoring the chair position. The sensing mechanisms are employed in conjunction with a memory device to permit the user to define a particular position into which the chair will move any time the appropriate switch is closed by the user. The chair control system diagnoses malfunctioning chair components and generates and displays data indicating the particular malfunctioning component.
