Occupant determining device

摘要

An occupant determining device includes a load detecting sensor provided on a seat body and a controller. The controller calculates a detected load value based on an output value of the load detecting sensor and performs occupant determination based on the detected load value. The occupant determination state is switched to an adult determination state when a certain delaying time elapses after the detected load value exceeds a determination threshold. The controller sets plural determination thresholds, and the larger each determination threshold being exceeded by the detected load value is, the shorter the delaying time is set.
