ABSTRACT:
An inflatable seat belt apparatus is formed of an inflatable portion which is usually maintained in a band shape and has an envelope shaped elastic inflatable member inflated and deployed in a rough spindle shape by introducing gas generated by a first gas generating device. The gas generating device operates in case of exceeding a predetermined threshold. A webbing includes the inflatable portion and extends over at least a range directly contacting with an occupant. A tongue is fixed to an end of the inflatable portion and includes a gas path extending from the gas generating device. A buckle is detachably engaged with the tongue. The envelope shaped inflatable member is inflated in a predetermined shape by introducing gas for a leak testing from a second gas generating device when the tongue is engaged with the buckle, and is inspected whether or not the gas leaks by a gas leak detecting device disposed in the gas path. A state of the damage is inspected.
