An internal tensioning structure (3) for use in an inflatable product fulfills the basic function of maintaining two adjacent inflatable surfaces (1, 2) in a desired geometric arrangement when the inflatable product is pressurized. The tensioning structure (3) is formed by connecting a pair of plastic strips sheets (31) via spaced-apart strands (32), such as strings or wires. When pulled taut, the strands (32) provide a high tensile strength between the two opposed plastic strips (31). At the same time, the plastic strips (31) facilitate a strong, long-lasting weld between the tensioning structure and the inflatable product. |
