Abstract

A device and a method for differentiating between a person sitting on the seat surface of a vehicle seat and an object such as, for example, a child seat. The device has a cushion provided with weight sensors which are distributed over the seat surface in a plane manner, first weight sensors being arranged in a central region and second weight sensors being arranged on the edge of the seat surface. At least one central weight sensor is differentiated from a plurality of second weight sensors on the edge of the seat surface in that it always emits a comparatively low sensor signal when subjected to the same weight load.
