Abstract
A patient transfer chair is disclosed which can be manually operated preferably by using a lever and spring helping device to assist in the transfer of a patient to and from a bed to and a wheelchair, chair, or other seat design. In transferring a patient from a chair to a bed, the lever is used by an attendant to assist the patient back and onto a transfer bed device. A spring helping device can be optionally used to assist in the transfer. Accordingly, a substantial reduction in the costs to design, manufacture, and operate a transfer chair is achieved while maintaining the same degree of comfort, safety and ease of prior patient transfer system designs.
