More Information
Summary:Disclosed is a system for detecting seat occupancy in a vehicle, comprising a microwave transmitter and several reflectors which are provided with a small area and are disposed within a vehicle seat, especially within the backrest of the vehicle seat. A greater or smaller number of reflectors are enabled if a person occupying the seat leans forward, resulting in a jump in intensity each time an additional reflector is enabled. Said jumps in intensity can be used in an advantageous manner for detecting the exact position of the person on the seat. In particular, an airbag can be prevented from deploying and the risks associated therewith can be avoided when the person leans far forward. Alternatively, receivers can be disposed within the seat instead of reflectors.
