Woven inflatable devices and method of making the same

An inflatable kiteboard harness, comprising:

• a laminated sheet formed in a planar shape and configured to be inflated and folded to transform to a three-dimensional kiteboard harness shape, wherein the laminated sheet includes:
• multiple inflatable regions including an inflatable central lumbar region, an inflatable right lumbar region, and an inflatable left lumbar region, a pair of flaps being attached to lateral outside edges of at least the inflatable right lumbar region and inflatable left lumbar region, respectively;
• a first folding seam between the inflatable left lumbar region and the inflatable central lumbar region, and a second folding seam between the inflatable right lumbar region and the inflatable central lumbar region, each of the first and second folding seams having a seam-crossing passage positioned across the corresponding first or second folding seam that enables fluidic communication across the respective seam;
• and
• an air inlet positioned in the inflatable regions,
• wherein the air inlet is configured to receive air from an inflator to raise the air pressure inside the multiple inflatable regions, to transform the laminated sheet from the planar shape to the three-dimensional kiteboard harness shape in an inflated state, and
• wherein each of the multiple inflatable regions includes interior yarn stretching from interior front side to an interior back side of the laminated sheet, the yarn being configured, when the inflatable regions are inflated, to be stretched taut and define the three-dimensional kiteboard harness shape for each of the multiple inflatable regions in the inflated state shape.
