A control apparatus for an occupant protection device in a motor vehicle, including an apparatus for classifying an object and/or occupant on a motor vehicle seat is provided. The control apparatus includes a capacitive force sensor for recording a weight force acting on the motor vehicle seat, which is realized as a measurement capacitor which has at least one elastic, and therefore deformable, plate. The sensor signal is supplied to a control and evaluation circuit which allows the sensor signal to be classified, according to the weight or according to the weight distribution and therefore according to the position of the occupant and/or of the object on the motor vehicle seat, and controls the occupant protection device as a function of the classification. This provides a very robust control apparatus which is of straightforward design and permits very reliable classification and accordingly ensures reliable control of the occupant protection device.
