1. A device for recognizing a child'"'"'s seat which is strapped to a front passenger'"'"'s seat of a motor vehicle, comprising:
- a base station arranged in an interior of the motor vehicle, said base station emitting an electromagnetic measurement field;
an identification carrier fitted to the child'"'"'s seat, said identification carrier physically changing said electromagnetic measurement field in a characteristic manner;
wherein a change in the measurement field is recorded by the base station;
wherein, when a change in the measurement field occurs which is characteristic of an occupancy of said child'"'"'s seat equipped with said identification carrier, said base station emits a corresponding identification signal; and
wherein a base antenna is an integral component of a seat occupancy sensor which is constructed as a sensor mat which comprises a conductor track constructed so as to detect the occupancy of the child'"'"'s seat.

Abstract
A device for recognizing a child'"'"'s seat which is strapped to the front passenger'"'"'s seat of a motor vehicle is provided. Such a device is required in order to inhibit release of a front seat passenger'"'"'s side airbag when a child'"'"'s seat is strapped on the front passenger'"'"'s seat. An identification carrier, for example, an electrical tuned circuit or an intelligent data carrier, which attenuates an electromagnetic measurement field in a characteristic manner, is fitted to the child'"'"'s seat. The presence and, possibly, also the type of child'"'"'s seat used can be recorded.

15. A device for recognizing a child'"'"'s seat which is strapped to a front passenger'"'"'s seat of a motor vehicle, comprising:
-
a base station arranged in an interior of the motor vehicle, said base station emitting an electromagnetic measurement field; an identification carrier fitted to the child'"'"'s seat, said identification carrier physically changing said electromagnetic measurement field in a characteristic manner; wherein a change in the measurement field is recorded by the base station; wherein, when a change in the measurement field occurs which is characteristic of said identification carrier being moved into the measurement field, said base station emits a corresponding identification signal; and wherein a base antenna is an integral component of a seat occupancy sensor which is constructed as a sensor mat.
