An inflatable seatbelt system designed so that the thickness of the webbing, when maintained in a strap-like configuration, is minimized, and it is possible to eliminate the webbing folding process and to reduce the amount of base fabric used and yet possible to reliably inflate the webbing when an emergency situation occurs. A shoulder belt (2) is formed from a tubular webbing (17), a tube (16) inserted in the webbing (17), and a cover (15) covering the webbing (17). The tube (16) is made of an elastic material which can be formed relatively thin and which has heat resistance and relatively high strength, e.g., urethane rubber or silicone rubber. The cover (15) is made of a resin material, e.g., polyester. The webbing (17) is made of a knitted fabric formed into a tubular configuration by weft knitting. By the use of the knitted fabric, the webbing (17) is stretchable to a large extent in the lateral direction but does not practically stretch in the longitudinal direction. |
