Abstract:
An internal tensioning structure for use in an inflatable product fulfills the basic function of maintaining two adjacent inflatable surfaces in a desired geometric arrangement when the inflatable product is pressurized. The tensioning structure is formed by connecting a pair of plastic strips sheets via spaced-apart strands, such as strings or wires. When pulled taut, the strands provide a high tensile strength between the two opposed plastic strips. At the same time, the plastic strips facilitate a strong, long-lasting weld between the tensioning structure and the inflatable product.

Abstract:
A multi-chamber inflatable mattress includes a main air chamber, upper and lower peripheral air chambers, and an upper air chamber. The main air chamber includes internal tensioning structures which cooperate with a bottom mattress panel and a lower intermediate panel to provide a generally box-shaped, mattress-sized inflatable structure upon pressurization. A second, upper intermediate panel cooperates with a top mattress panel to define an upper air chamber which defines the sleeping surface. The main air chamber receives pressurized fluid directly from a valve, while the lower and upper peripheral air chambers are in direct fluid communication with the main air chamber but not the valve. The upper air chamber is in direct fluid communication with the upper peripheral air chamber, but not the main chamber or valve.

An inflatable spa is disclosed having improved strength. A water cavity of the inflatable spa may receive massaging air bubbles and/or jetted water.
