Abstract
An airbag formed to have a series of nodes therein, each node defined by pinching and jointing a portion of alternate opposing sides of a tubular structure so that each node lies generally in a plane at 90° (or near 90°) with respect to an adjacent node. The pinch points or joints are preferably short segments or small areas where the opposing sides are jointed by heat welding, sewing, ultrasonic welding, by adhesives, or by weaving.
