An inflatable seat belt apparatus is formed of an inflatable portion which is usually maintained in a band shape and has an envelope part inflated and deployed in a spindle shape by introducing a gas generated by a gas generating device, the gas generating device acting in case of exceeding a predetermined threshold, a webbing having the inflatable portion extending over at least a range directly contacting with an occupant, a tongue fixed to an end of the inflatable portion and having a gas inlet from the gas generating device inside thereof and a buckle which detachably engages the tongue. The envelope part is made of a knitted fabric expanded in the weft direction in a range of contacting the chest of the occupant when the envelope part is inflated. The inflatable seat belt apparatus includes an inflation restricting device for restricting the expansion in the weft direction besides the range.

[ What is claimed is:] [10.]10. An inflatable occupant protection device comprising:an elongated webbing;an inflatable member;a fabric member connected to the elongated webbing to cover the inflatable member, wherein the fabric member expands in a direction transverse to a longitudinal direction of the elongated webbing upon inflation of the inflatable member, thereby pre-tensioning the elongated webbing; anda cover disposed over the fabric member, wherein the cover restricts the shape and volume of the inflatable member after the inflatable member is inflated and deployed;wherein the cover has a joining portion extending along the longitudinal direction of the elongated webbing, the joining portion having a first part and at least one second part, the first part being weaker in strength than the second part; andwherein the joining portion of the cover is not attached to the fabric member..Iaddend..Iadd.
