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.
Claims13
In combination with an apparatus for detecting a child safety seat placed on a seat of a motor vehicle, an antenna configuration integrated in the seat of the motor vehicle, the antenna configuration comprising:
- a single loop-shaped transmitting antenna for transmitting an electromagnetic exciter field and two loop-shaped receiving antennas for receiving electromagnetic measurement fields.
An apparatus for detecting a child safety seat placed on a seat of a motor vehicle, comprising:
- an antenna configuration integrated in a seat of a motor vehicle, said antenna configuration having a single loop transmitting antenna for transmitting an electromagnetic exciter field and two loop-shaped receiving antennas for receiving electromagnetic measurement fields;
- a control device connected to said transmitting and receiving antennas for impressing the electromagnetic exciter field on said transmitting antenna, evaluating the measurement fields picked up by said receiving antennas, and generating a status signal as a function of the evaluated measurement fields.
