ABSTRACT:
A seating system which can be adapted to the particular body size and required spatial orientation of a disabled person to hold him securely and in an orthopedically correct required position, and which can be fitted to any patient in a manner that minimizes the amount of custom craft work and cost. The seat includes a frame having three shells, including a lower seat back shell that can pivot and shift relative to the seat bottom shell and the upper back shell. A cushion system which includes a group of individual cushions can be rapidly installed on the shells to closely fit the individual. The shells can be independently adjusted to control the general contour of the thighs, back, hips and shoulders. Different cushions can be chosen to closely control the patient's orientation and to snugly but comfortably fit him into the adjusted frame. Close fitting of a patient's trunk and the region above the hips, for a wide variety of body types, is enabled by the use of a three-cushioned lower back arrangement, which includes a lower back cushion that supports only the back, and a pair of side cushions located at either side of the back cushion and projecting forward of it to lie on either side of the patient. The modular side cushions are chosen from a group of such cushions, which provide proper lateral positioning and closely fit the person.
