Abstract
Arrangement for detecting the occupancy of a seat for safety systems having a plurality of light emitters, which are imaged onto the seat via an optical unit and the luminous spots created there are imaged via a further optical unit onto a photodetector field. The contour is acquired with a microprocessor via the evaluation of the position of these luminous spots on the photodetector field, and thus the type of occupancy is determined. This information can be supported via passive IR detectors for the acquisition of the temperature differential.
