Abstract
Energy absorbing webbings that are generally flat and that have a controllable elongation distance are provided. The webbings are comprised of elongation yarns, such as partially oriented yarns (POY), and ground yarns. In certain embodiments, because they are generally flat, the energy absorbing webbings are suitable for use in retractors. Also provided are processes of manufacturing generally flat, energy absorbing webbings. In certain embodiments, the webbings are subjected to heat using first and second set of rollers with various feed ratios.
