Abstract
A predetermined tension force is generated to an air belt even when an expandable portion is expanded in a narrow space. An air beltincludes a first normal belt, a second normal belt, and an expandable portiontherebetween. In order to regulate a thickness of the expandable portionin an expanding operation, portions of the expandable portionfacing each other are coupled by means of a coupling portionformed of a stitching thread. The expandable portionincludes a bag-shaped beltand a knit coverthat is not extended in a longitudinal direction. When an inflator is operated, the expandable portionis expanded and the air beltfits an occupant. At this moment, since the knit cover of the expandable portionis not extended in the longitudinal direction of the air belt, a length of the expandable portionis reduced along with an expansion of the expandable portionand the tension force is generated to the air belt
