ABSTRACT:
Disclosed is an infant-restraining protective seat having an inflatable seat belt, in which an infant seat belt (6) is maintained in the shape of a belt under ordinary conditions. When the a tongue (5) is engaged with a buckle device (4) in order to fasten the belt, gas flow holes (4a) and (5a) are brought into registration to form a single gas flow passageway. Under ordinary conditions, however, the gas flow holes (4a), (5a) are closed by caps (11), (12). Since a gas generator (9) does not operate under ordinary conditions, the protective seat (1) exhibits an infant-restraining function similar to that of the conventional protective seat for infants. At the time of an emergency, the gas generator 9 generates a high-pressure gas that breaks the caps (11), (12) and flows into the infant seat belt (6). As a result, the infant seat belt 6 inflates substantially instantaneously and in reliable fashion. Accordingly, a seated infant is restrained by the inflated seat belt 6 in a reliable manner.
