  • Patent number: 7028493
    Abstract: In a vehicle air conditioner, a front air conditioning unit and a seat air conditioning unit are automatically controlled by an air conditioner ECU. If a seat air conditioner switch is operated by a user during an automatic control, the setting (e.g. air volume of a seat blower) of the seat air conditioning switch is learned. Based on the learning, a seat blower characteristic diagram, which is stored in a ROM, is changed. Therefore, from this time onward, under the same environmental condition, the seat blower air volume is determined based on the changed seat blower characteristic diagram. Accordingly, a seat air conditioning is provided as desired.

  • Patent number: 6928829
    Abstract: In a seat air conditioning unit for a vehicle seat constructed with a seat cushion and a seat back, when a seat air conditioning operation is performed in a cooling operation of a passenger compartment, a cooling capacity of cool air blown from the seat back is set smaller than a cooling capacity of cool air blown from these at cushion while a passenger sits on the vehicle seat. Further, the cooling capacity of cool air blown from a lower portion of the seat back can be set smaller than the cooling capacity of an upper portion of the seat back. Accordingly, even when the cooling operation is continued for a long time while the seat air conditioning operation is performed, the waist portion of the passenger can be prevented from being excessively cooled.

  • Patent number: 6179706
    Abstract: A seat air conditioner for a vehicle has a seat having a pad and a blower unit for forcibly blowing conditioned air toward the seat. The pad has an introduction passage for introducing blown air toward a surface of the pad, plural distribution passages communicating with and radially extending from the introduction passage and plural communication passages causing communication among the distribution passages. Each of the distribution passages and the communication passages is formed as a groove in the surface of the pad. Therefore, even when a passenger is seated on the seat, air does not stagnate but flows into the distribution passages extending outside a portion of the seat which contacts with the passenger through the communication passages. As a result, air is smoothly blown out from the seat, and the passenger immediately feels sufficiently warm and comfortable.
