Abstract:
A convertible inflatable furnishing which comprises an inflatable base including a base upper skin which forms a layer of the upper side of the base, a base lower skin which forms a layer of the lower side of the base, and a rim side which links the edge of the upper side of the base to the edge of the lower side of the base, an inflatable backrest, a fixing means to fix the backrest to the base upper skin, and an air passage between the base and the backrest allowing a flow of air between the inside of the base and the inside of the backrest when loads on the base and backrest change; said fixing means consists of a flexible closed-loop strip forming a single hole with the internal surface of the flexible closed-loop strip not substantially adhered to itself at any place to form a hinge, an upper edge of the flexible closed-loop strip permanently connected to a lower end of the backrest and a lower edge of the flexible closed-loop strip permanently connected to the base upper skin; said fixing means is sufficiently flexible to allow the backrest to recline increasingly with deflation of the backrest including when the backrest is under an increasing load, and allow the backrest to erect increasingly with inflation of the backrest including when the load on the backrest is reducing.
