摘要： Apparatus and method are disclosed which pertain to inflatable structures useful as air beds and the like. Shape and load control are facilitated by a plurality of bladders that are located within an inflatable chamber of the structure and are joined to opposed imperforate walls thereof. The bladders are provided with vents which lend to the interior of the chamber, and upon inflation of the structure and resultant separation of the opposed walls of the chamber, the bladders are caused to extend from a flattened state, become filled with the fluid used for inflating the structure, and assume a roughly cylindrical convoluted configuration. Being made of a flexible, substantially non-extensible material, such a vinyl plastics, there is a limit to which the bladders can extend, and further vertical separation or lateral shifting of the attached opposed walls is thereby restrained. When the bladders are provided with vents, they "breathe" when a physical load is applied to the inflated structure or removed from it, hence, regulating resiliency by means of an "air spring" effect.

摘要： An air chamber including a control for manually selecting a desired pressure within the chamber. Means for sensing the air pressure within the chamber are provided as are pump means for adding air to the chamber and vent means for removing air from the chamber. Control circuitry adds or removes air from the chamber responsive to the sensed pressure to maintain the pressure within the chamber at the preset level. Structural means are provided within the chamber for supporting a portion of a load placed thereon and thus decreases air pressure within the chamber to avoid deflation.
