Abstract:
A flotation support system including a generally rectangular air frame, which is defined by a tubular air-filled member which surrounds an open region. A base sheet extends beneath the open region and is secured to the tubular member to define with such member a nesting receptacle for a fluid-containing envelope. The base sheet passes beneath the said frame and is secured to the tubular member toward the outer peripheral border thereof, to provide a receiving slot between the lower side of the tubular member and the adjacent portions of the sheet. The envelope has dimensions exceeding that of the open region, so that the peripheral portions of the envelope are received into the said slot. The peripheral portions of the envelope are elastically constrained by the slot, to thereby constitute a buffer volume for liquid displaced from the central portion of the envelope in consequence of an individual being emplaced upon such central portions, to thereby provide improved cushioning characteristics. The air frame also acts as a restraining bumper, which renders the assembly ideal for use in cribs or so forth.
