Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
153 words
Device for recognising seat occupancy in vehicles, in which a light emitter (101) directed at the seat as
well as a detector (102) are provided, wherein the
detector (102) receives the reflections occurring on the
seat or on the the person located thereon, and evaluation takes place with a processor (202), characterised in that an arrangement (100) for detecting a linear or two-dimensional
image of the seat is provided, consisting of a) a plurality of light emitters (101) directed at the seat
in order to detect the contour of the seat in the form of
spots of light, and b) a photodetector array (102) onto which the spots of light
are imaged is disposed at a defined distance from the
seat, and the detected image is processed with the processor (202), so
that it is possible to distinguish between the seat being
occupied by a person, by an object or not being occupied.
