摘要： PROBLEM TO BE SOLVED: To provide a three-point fixed type seat belt air bag in which a seat belt having a first end portion attached at a floor and a second end portion wound into a retractor is passed through an insertion fixture, which is engaged with a buckle on the floor, and which has a knee portion and a body portion. SOLUTION: This seat belt airbag comprises a seat belt tube formed out of flexible woven fabric in a flat belt shape in a non-expanded condition. The expandable airbag member is accommodated in a woven fabric tube. The fiber tube is extended from a fixed end portion to the body portion of the seat belt through the insertion fixture. Part of the overall length of the airbag member is accommodated in reinforcement sleeves extended to the body portion. When the airbag is pressurized during operation of the airbag, the airbag member is expanded to such dimensions as to form a gas conduit in a range surrounded by the reinforcement sleeves, however, the reinforcement sleeves will not break off. On the other hand, the seat belt tube breaks off at the front portion than the opening end portion of the reinforcement sleeves of the airbag, and the airbag is expanded to the outer periphery of the airbag.
