Abstract
Disclosed is a sensor mat for determining a seat occupation situation of a vehicle seat. Said sensor mat comprises a plurality of sensor cells which can be allocated to a sitting area of the vehicle seat and are configured and interconnected in such a way that an output signal of the sensor mat varies in accordance with the seat occupation situation. At least one first sensor cell and a second sensor cell are interconnected to a pair of sensor cells such that the output signal of the sensor mat exceeds or lies below a predefined threshold value independently of the triggering state of the other sensor cells when the first and the second sensor cell are triggered simultaneously.

- 12. A sensor mat for determining a seat occupation situation for a vehicle seat, comprising a plurality of sensor cells to be associated to a seating area of a vehicle seat, wherein the sensor cells are configured and interconnected in such a way that an output signal of the sensor mat varies as a function of the seat occupation situation, wherein said plurality of sensor cells comprises at least a plurality of first sensor cells and a plurality of second sensor cells, said plurality of first sensor cells and said plurality of second sensor cells being operatively connected to form a sensor cell group in such a way that under normal operating conditions of the sensor mat an output signal of the sensor mat exceeds or drops below a predefined threshold value only if at least one sensor cell of the plurality of first sensor cells and at least one sensor cell of the plurality of second sensor cells are simultaneously triggered.
