US Patent 7322064 Inflatable bed

An inflatable bed includes bottom and top sheet layers, a surrounding sheet that interconnects the peripheral ends of the bottom and top sheet layers and that cooperates with the bottom and top sheet layers to form a bed body which defines an air chamber, a plurality of spaced-apart tension members disposed within the air chamber, and an inner partition sheet spaced apart from and surrounded by the surrounding sheet. Each tension member has two ends connected respectively to the bottom and top sheet layers. The inner partition sheet is connected to the bottom and top sheet layers so as to divide the air chamber into first and second air chambers. The first air chamber is defined between the surrounding sheet and the inner partition sheet.
