    摘要： A capacitance type sensor installed in a vehicle includes the first electrode, the second electrode, and the third electrode. The first electrode is arranged inside a seating portion of a seat or a backrest portion of the seat, or both. The second electrode is arranged adjacent to the first electrode inside at least one of the seating portion and the backrest portion of the seat, whatever the first electrode is arranged. The second electrode forms an electric field together with the first electrode between them in a wetness determination mode in which a wet condition of the seat is determined. The third electrode forms an electric field together with the first and the second electrode between them in an occupant determination mode in which an occupant in the seat is determined.

    摘要： A seat occupant identifying apparatus for automotive occupant restraint system is provided which works to identify whether a seat occupant is an adult passenger or a child passenger. When a total output value of a plurality of seat load sensors is greater than a given adult identifying threshold value, it is determined that the seat occupant is an adult. Afterwards, when the total output value decreases below the adult identifying threshold value due to, for example, a lateral G-force acting on the seat occupant during cornering of the vehicle, and an output of either of the right and left seat load sensors is lowered below a preselected cornering threshold value, while the other output is higher than it, the latest determination that the seat occupant is an adult is kept as it is. This provides for high accuracy seat occupant identification during cornering of the vehicle.

    摘要： A device for detecting a tensile force of a seat belt composed of an elastic plate having a strain gauge mounted thereon and a protecting plate overlapped on the elastic plate is installed in a seat belt. Under a normal situation, seat belt tensile force is applied only to the elastic plate which is deformable according to the tensile force. The elastic plate is broken when a high tensile force exceeding a predetermined level is applied thereto, while the protecting plate remains unbroken by such a high tensile force. The seat belt tensile force under the normal situation is precisely detected by the strain gauge mounted on the elastic plate, and the seat belt function to protect a passenger is maintained by the protecting plate when the high tensile force is generated by an accidental collision or the like.
