The automotive seat is the significant man machine interface in automobiles. The covering fabric of the seat is one of the important factors in designing the comfortable seat. A target is to predict the hand feel of a given seat from the physical properties of covering fabrics. It is necessary to establish the subjective words of judgement for the hand feel of seat covering fabrics and relate them to the objective measurement of physical properties. In this paper, the factor analysis was used to investigate the subjective words of the hand feel for covering fabrics of automotive seats. The correlations between the hand feel and the physical properties of covering fabrics were examined by the correlation analysis.The 'hand feel' of each covering fabric used into surface layer of seven seats on the market was judged by the Scheffe's method of paired comparison. From the result of paired comparison, the mean scores of seven fabrics for each sensory adjective were computed using the Scheffe'-Haga method. The factor analysis was used to study eight adjectives defining the hand feel from the calculated mean preference scores. From the correlation between the physical properties of each covering fabric and each mean preference score of eight adjectives, the adjective 'high-class' has a positive correlation with the surface property, the thermal conductivity and the coefficient of dynamic friction, and has a negative correlation with the variation of coefficient of friction. It is found that the 'sporty', the 'high-class' and the 'smooth' feelings of seat fabrics are correlated to their surface friction and thermal character.
