  • Wheelchair seat assembly with contoured seat pan and cushion and method
    Patent number: 5857749
    Abstract: A seat assembly (21) for a wheelchair including a relatively rigid seat base (12) of substantially uniform thickness with an upwardly facing contoured top surface (14) and a cushion assembly mounted on the seat base. The cushion assembly includes a relatively soft foam member (30) substantially covering the seat base (12) for localized deformation of the foam member and for communication of the influence of contours on the seat base (12) through the foam member (30) to the user. In the preferred form, a flexible pouch (40) having a viscous fluid-like material contained therein is positioned in a recess (38) in the foam member (30) in the area of the user's ischial tuberosities and coccyx, and a water-impervious, flexible elastomeric envelope (50) completely surrounds the foam member (30) and the fluid-containing pouch (40).
