ABSTRACT:
Disclosed is an inflatable seat belt apparatus in which, under ordinary conditions, a bag-shaped belt, (2b) is maintained in a belt-shaped form. When a tongue (5) is engaged with a buckle device (4) in order to fasten the belt, a gas-flow hole (4a) and a gas-flow hole (5a) are registered with each other to form a single gas-flow passageway. Under normal conditions, however, the gas-flow holes (4a), (5a) are shut by caps (11), (12). At, this time a gas generator (9) does not operate and therefore the seat belt apparatus (1) performs a passenger restraining function similar to that of the conventional seat belt apparatus. In the event of an emergency, the gas generator (9) generates a gas which breaks the caps (11), (12) and flows into the bag-shaped belt (2b). As a result, the bag-shaped belt, (2b) expands substantially instantaneously and in a reliable manner. This makes it possible for the passenger to be reliably restrained by the bag-shaped belt (2b) inflated in this manner.
