ABSTRACT:
The present invention relates to an alternating inflatable support for the human body. The invention includes a flexible pillow having a plurality of fluid impervious pockets therein which are substantially flat when deflated, but which support an adjacent section of the human body when inflated with a fluid under pressure. The pockets are interspersed and grouped into an operably coupled first set of pockets and an operably coupled second set of pockets. A pump is provided which includes at least one pumping chamber for receiving and expelling fluid under pressure. A solenoid is operably coupled to the pumping chambers for compressing and expanding the pumping chambers. A valve is operably coupled between the pump and the flexible pillow for alternately inflating and exhausting the fluid through the first set of pockets and the second set of pockets, thereby alternately supporting the interspersed sections of the body adjacent to the first set of the pockets and the second set of pockets.
