| 1. An occupant determining device, comprising:
a load detecting sensor provided on a seat body; and
a controller calculating a detected load value based on an output value of the load detecting sensor and performing occupant
determination based on the detected load value,
wherein the controller sets a first determination threshold and a second determination threshold larger than the first determination
threshold,
wherein if the detected load value falls between the first and second determination thresholds and continues for a first time
duration, the controller switches an occupant determination state to an adult determination state, and
wherein if the detected load value exceeds the second determination threshold and continues for a second time duration which
is shorter than the first time duration, the controller switches the occupant determination state to the adult determination
state.
