Seat occupancy sensor

Seat occupancy sensor

A seat occupancy sensor has at least two pressure-activatable switch elements, which are assigned to two areas of a seat and are spaced a distance apart from one another and connected in a logic AND operation arrangement. An electric resistance element is connected in parallel to each switch element...

description A seat occupancy sensor has at least two pressure-activatable switch elements, which are assigned to two areas of a seat and are spaced a distance apart from one another and connected in a logic AND operation arrangement. An electric resistance element is connected in parallel to each switch element, its resistance value being between the resistance values when the switch element is activated and when the switch element is not activated. Each switch element can have a plurality of parallel connected sensor cells interconnected in a logic OR operation arrangement and distributed over a zone of the seat so that occupancy at any location within this zone is recognized as seat occupancy by one of the sensor's switch elements.
