  • Temperature detector for an air-conditioned vehicle seat
    Patent number: 6541737
    Abstract: A temperature detector for an air-conditioned vehicle seat with seat heating and/or seat ventilation is disclosed. To ensure accurate temperature measurement for regulation purposes close to the surface of the seat cushion while eliminating purely local temperature peaks, the temperature detector is provided with a flat, extended heat absorption surface, which is preferably formed by a thin, flexible layer of good thermal conductivity in which a temperature sensor in button or disc form is firmly embedded.
