Abstract
A system for recognizing the occupancy of a seat, containing elements made of electrically conducting synthetic material, especially strips made of electrically conductive polyurethane. A seat equipped with the system. A method for recognizing seat occupancy whereby an alteration in resistance of the electrically conductive material occurring in a change of weight is detected.
Claims33
Surface heating with a carrier and a heating layer, which contains electrically conductive plastic, characterized in that the heating layer is formed by a flexible film and that the carrier is flexible.
Method for the production of a surface heating, wherein a heating layer with electrically conductive plastic is bound with a carrier, characterized in that the heating layer is formed by first applying an electrically conductive, in particular, foaming or foam-plastic material on the carrier and the curing the plastic material on the carrier.
Method for the production of a surface heating, wherein a heating layer with electrically conductive foam is bound with a carrier, characterized in that the heating layer is produced from an electrically conductive, in particular, foaming or foam-plastic material and is then affixed on the carrier.
Seat occupancy recognition, characterized in that elements made of electrically conductive plastic are contained.
Seat occupancy recognition method, characterized in that a resistance change is detected in an electrically conductive plastic material as a result of a weight loading of the material.
