Claim One:
1. A system for classifying vehicle occupants, comprising: a detector installed in a vehicle seat and adapted to sense variation in current occurring when an occupant is seated in the seat; and a controller for determining whether the occupant is seated and which type of occupant is sitting, using a current value measured by the detector, and transmitting a result of determination to an airbag control unit, the controller operating, wherein the controller compares the measured current value (X) with a preset zero value, infant maximum value (Acrs), adult minimum value (Aadt), and threshold value (Athd) existing between the infant maximum value and the adult minimum value, and thus determines that no occupant is seated when X=zero value, that an infant is seated when zero value <X<Athd, and that an adult is seated when Athd≦X<Aadt, the controller changes determination thereof in such a way that, when Acrs≦X<Athd, an occupant is determined to be an adult when a current value, measured after this condition is met, is equal to or greater than the adult minimum value (Aadt), and the controller changes determination thereof in such a way that, when Athd≦X<Aadt, an occupant is determined to be an infant when a current value, measured after this condition is met, is equal to or less than the infant maximum value (Acrs).
