  • Patent number: 5079790
    Abstract: A wheel chair cushion and the like is disclosed which includes a cushion formed of a deformable resilient material. The cushion includes a base having a front wall and a rear wall. A plurality of individual foam springs are carried by the base having support surfaces which lie in a plane that is inclined to the base surface of said base as extending from said front wall to said rear wall. A pressure relief cut-out is formed substantially in its entirety from a mid-line of said cushion rearwardly so as to be disposed underneath the buttocks of a person sitting on the cushion to relieve pressure in that area and provide increased compressibility of the foam springs in the pressure relief area to disperse pressure and provide a resilient depression in the cushion to enhance the patient retention capability of the cushion as used in a wheel chair.
