Abstract

Bed covers (20) which can be elevated above a bed (50) solely as a result of differential air pressure. A small blower unit (80) located under the bed (50) supplies air to an air-flow channel network (22) making up the central portion of the bed covers (20). The air-flow channel network (22) is made up of fabric layers which are joined along selective linear alignments (46 and 48) to produce air flow channels (40, 42, and 44). The upper (24) and middle (28) fabric layers are less permeable to air flow than the lower layer (32). The air flows from the blower (80) through a conduit (82) into the air-flow channel network (22), throughout the network (22), and thence through the bottom fabric layer (32). The uniform distribution of air through the bottom layer (32) creates a region of higher pressure under the bed covers (20), thus causing the formation of a cavity (60) between the bed covers (20) and the bed (50).
