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.

Abstract: In an occupant detection or classification system for a motor vehicle, a sensor mat (2) measures the pressure or pressure distribution on a seating surface. A control unit (4) receives the signals from the sensor mat (2) representing an occupancy of the vehicle seat. The temperature of the foam core (1) underlying the seating surface is measured at a location other than in the center of the foam core and, specifically, at the control unit (4).

Abstract: An antenna configuration in an apparatus for detecting a child safety seat placed on a seat in a motor vehicle. A single transmitting antenna formed as a loop surrounds two loop-shaped receiving antennas. The receiving antennas receive electromagnetic measurement fields originating from an electromagnetic exciter field transmitted by the transmitting antenna.
