1. An occupant determination apparatus comprising:

  • a load sensor that measures a weight of an occupant seated on a seat of a vehicle as a measurement weight; and

    a determinator determining the weight of the occupant as one status among a plurality of statuses which are set corresponding to the weight based on the measurement weight measured by the load sensor,wherein the determinator;

    determines the weight of the occupant as an instantaneous status among the plurality of statuses, based on the measurement weight measured for each unit time;

    invalidates a determination result of the instantaneous status when an acceleration acting on the vehicle exceeds a threshold acceleration set in advance; and

    continues to invalidate the determination result of the instantaneous status for each unit time during a predetermined time after the acceleration acting on the vehicle changes from exceeding the threshold acceleration set in advance to not exceeding the threshold acceleration set in advance.
