ABSTRACT:
A convalescent chair for hospital and nursing home patients and the like including a chair structure forming a back rest, arm rests and shoulder and head support for patients. A seat support structure is pivotally connected to the forward portion of the chair structure and is elevated by a motorized jack from a substantially horizontal position to an inclined position to assist in raising a patient from the seated position to the standing position. A plurality of air sacs and a therapy pad are supported by the seat support structure and are supplied filtered and cooled air to provide sufficient air flow for inflation of the air sacs and for effective discharge of air from the upper portion of the air sacs. An air distribution conduit extending from a blower to an air supply manifold in assembly with the seat support structure forms a heat exchanger portion so that air being drawn through an internal chamber of the chair by an exhaust fan imparts cooling to air flowing through the air distribution conduit.
