A device for detecting seat occupancy in a motor vehicle, especially for inhibiting airbag release when a seat is unoccupied, is provided. A seat occupancy sensor has a front sensing region and a rear sensing region, which can be evaluated separately. In this way, it is possible to determine whether the front seat passenger is in a sitting position close to the front seat edge of the seat cushion, which reduces the protective effect of the airbag. This can possibly be indicated visually or audibly. As a further measure, the inhibiting of an airbag release can be provided in the case of an incorrect sitting position. The seat occupancy sensor can be a resistive membrane pressure sensor.

A device for detecting seat occupancy states in a motor vehicle, the device comprising: a seat occupancy sensor integrated in a seat cushion of the seat; an evaluation circuit coupled to the seat occupancy sensor; wherein said seat occupancy sensor is divided into a front sensing region and a rear sensing region, said front sensing region responding to seat occupancy in a front region of the seat cushion close to a front seat edge, and the rear sensing region responding to seat occupancy in a rear region of the seat cushion; wherein an occupancy state of both said front and rear regions is separately evaluated by said evaluation circuit; and whereby a response from only said front sensing region indicates an incorrect seat occupancy state for an airbag release.
