ABSTRACT:
A support system (A) including a cushion (B) for uniformly distributing the weight of an individual uniformly and further circulating air along the individual's body. The cushion (B) has porosity and air cells (4) which project upwardly from the base (2) and are in communication through the base (2) so that all exist at the same air pressure. The base (2) has apertures (14) between the cells (4). The system includes a distributor (20) beneath the cushion base (2) and a duct (30) which connects to one side of the distributor (20). The distributor (20) has a plurality of blunted pillars (24) which support the cushion (B) above the distributor base (22) and create a distribution and access chamber (F) beneath the cushion base (2). The duct (30) can have a vertical section (34,40) connected to a container (42) for collecting liquids. A blower (D) discharges conditioned air into the distribution chamber (20) through the duct (30). The air escapes through the cushion base apertures (14) between the cells (4) so as to ventilate the surface area of that portion of the individual's body which is against the cushion. A vacuum blower (D) can also be used to reverse the air flow to assist fluid removal from the distribution chamber (20) and to vent odors. Liquid discharged onto the cushion (B) passes through the apertures (14) to the container (42).
