An inflatable belt includes an envelope-shaped or elongated belt body, which is folded in a long band-shaped configuration, and a cover enclosing the belt body. The belt body is made of a single piece of rectangular base fabric. The rectangular base fabric is folded about a longitudinal return line. The folded halves are then sewn about an outer periphery of an inflatable area so as to have an envelope-shaped or elongated configuration. Thus, the inflatable belt has a uniform thickness and feels better to the vehicle occupant when the inflatable belt is in contact with the vehicle occupant. Also, the inflatable belt has a shorter stitching length, thereby reducing cost, improving productivity, and reducing or preventing gas leakage.
