In this paper, a thermophysical model of the dynamic interactions between an automobile driver and a heated seat is presented. The contacting body is considered to be made of three layerscore, skin, and clothing-while the seat consists of several layers of fabric materials. Experimentally measured load distributions are used to identify the distribution of local thermal resistance across the contact areas and to determine the spatial and temporal variation in the temperature of the seat and of the driver's skin and clothing. The model, which has the ability to predict the transient response of a driver in a highly nonuniform thermal environment, has been tested under simulated winter conditions. The good agreement between model predictions and experimental measurements suggests that such a model can be a useful predictive tool in the design of automobile heated seat systems. The experimentally measured local thermal sensations can be beneficial to the vehicular seat designers.
