A belt body is formed in an envelope-like or elongated configuration by superposing two long base fabrics on each other and sewing them along their peripheries by a sewing yarn. A gas inlet is formed at one end side of the belt body. The inside of the belt body is divided by sewing yarns into a first chamber and two second chambers which extend in the longitudinal direction. The sewing yarns are weaker than the sewing yarn used to sew the periphery, so that the second sewing yarns are broken when the gas pressure in the first chamber reaches a predetermined value. The second chambers extend along both sides of the first chamber. One of the second chambers has a vent hole formed therein. In another embodiment, the belt body is divided into three chambers. The first chamber extends from the gas inlet to the vicinity of the middle and the third chamber extends from the other end toward the middle. The second chamber is located between the first chamber and the third chamber. These inflatable belts enable the sufficiently quick inflation of the inflatable belt without increasing the gas generating pressure of a gas generator and without hastening the completion of gas generation.

Inflatable belt and inflatable belt device

An air bag device that includes an inflatable shoulder belt,having an end in which a gas generator,is arranged. A retainer,holds the gas generator,and the shoulder belt,integrally. The gas generator,is movable along a guide rail,One end of the shoulder belt,is connected to a webbing,while the other end is connected to the lap belt,A retractor,retracts the webbing,while a retractor,retracts the lap belt,The tongue,is fastened to the buckle

Air belt apparatus

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.
