ABSTRACT:
This invention provides for a fluid cushion (10) defined by a fluid tight closed housing (22) which is deformable by applied load of a user (12). The fluid cushion (10) includes an upper surface member (24), a lower surface member (26) and an intermediate membrane (64) which divides the interior of the housing (22) into a first fluid medium containing chamber (62) and a second fluid medium containing chamber (60). A tubular mechanism (42) defines through passages (46) which are positionally located for insertion therein of particular bones of the human body. The tubular mechanism (42) has tubular sidewall members (50) which are contoured to provide an apex (52) at a substantially central location between the upper surface member (24) and the lower surface member (26) and allows for maintenance of the fluid mediums (21 and 20) within spaces (48) between openings (32 and 34). In this manner, a resilient, flexible, and deformable fluid cushion (10) is provided for a user (12) to relieve particular discomforting applied loads to the ischia spine bones of the user (12).
