An inflatable seatbelt system having a webbing (11) formed in the shape of a bag from a woven fabric. The warp of the webbing (11) is disposed in the longitudinal direction of the seatbelt, and the weft is disposed in the lateral direction of the seatbelt. The weft is formed of spandex threads made of a material having a relatively low modulus of elasticity and stretchable in a rubber-like manner, e.g., urethane. The weft (15) on the reverse side of a portion of the webbing (11) corresponding to the boundary between a shoulder belt (2) and a lap belt (3) is cut over a predetermined area. A gas outlet portion (5e) of a tongue (5) is inserted into the shoulder belt (2) from an opening 11(c) formed by widening the cut area of the weft (15). The lap belt (3) of the webbing (11), which extends in the opposite direction to the direction of insertion of the gas outlet portion (5e), is passed through a webbing receiving hole (5b) provided in an operating portion (5c) of the tongue (5) by slightly contracting the lap belt 3 in the direction of the width thereof. A belt cap (16) is fitted onto the gas outlet portion (5e) of the tongue (5) with the webbing (11) interposed therebetween, thereby securing the tongue (5) to the webbing (11).
