Abstract:
1. A detection device for passengers, comprising: a passenger judgment unit which makes a judgment on a state of a passenger on a seat of a vehicle and includes a specified load judgment unit and a stability judgment unit; a plurality of load sensors disposed on supporting parts which support the seat of the vehicle; wherein if a judgment is made that a summation of output values of the plurality of load sensors falls into a specified load range of a child-seat judged by the specified load judgment unit, an output value of at least one of the plurality of load sensors is stored as a first initial value, and the summation of the output values of the plurality of load sensors is stored as a second initial value, and the first initial value and the second initial value are compared with a detected output value of the at least one of the plurality of load sensors and a summation of detected output values of the plurality of load sensors detected when a stable state is judged by the stability judgment unit, respectively, and if a first increment between the detected output value of the at least one of the plurality of load sensors at the stable state and the first initial value is equal to or more than a second increment between the summation of the detected output values of the plurality of load sensors at the stable state and the second initial value, the passenger judgment unit judges that the child-seat is attached to the seat of the vehicle.
