摘要

The method involves relative twisting between at least two side sections. The axis of twist is in the main perpendicular to the plane of the unrolled gas bag. The section of the bag opposite the fastening section is movable relative to it, as is the transition section. Use is made of eight tensioning points equally spaced from each other along the transition section.
