ABSTRACT:
An inflatable seatbelt system having a webbing (11) formed by laying two strap-like webbing base fabrics (11a) and (11b) one on top of the other, which have a predetermined width approximately equal to the width of a typical conventional seatbelt, and sewing the respective side edges of these webbing base fabrics to each other at both lateral ends of the webbing (11). The warp (14) is disposed parallel to the longitudinal direction of the webbing (11), and the weft (15) is disposed perpendicularly to the longitudinal direction of the webbing (11). The warp (14) is formed of threads which do not practically stretch when the webbing (11) inflates. The weft (15) is formed of rubber-like stretchable threads made of an elastic material, e.g., urethane. Accordingly, the webbing (11) inflates to a large extent in the lateral direction, but it does not practically inflate in the longitudinal direction.
