    摘要: An occupant judging device for a vehicle seat includes a load sensor provided in the vehicle seat and a controller for calculating a detected load value based on an output load value from the load sensor and determining an occupant on the vehicle seat by comparing the detected load value and a predetermined threshold value. The controller judges by a decrease state of the detected load value detected after the seatbelt is fastened being maintained for a first predetermined time that a child restraint device is installed, when a state in which the seatbelt is fastened and the door is opened is detected. Further, the controller judges by a decrease state of the detected load value detected after the seatbelt is fastened being maintained for a second predetermined time that the child restraint device is installed, when a state in which the seatbelt is fastened and the door is closed is detected.

    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 first determination threshold. The controller sets the delaying time shorter when the detected load value exceeds the first determination threshold within a predetermined time after the detected load value exceeds a second determination threshold.
