| Research Abstract |
A sitting comfort of three automotive seats (a middle class car, a popular class car, and a mini-sized car), whose cushion angles were changed 0°, 8° or 15° and back angles, surface materials and pad shape were the same, was evaluated by only human tactile sensation while sitting on these seats. As the result of the sensory evaluation, three class seats whose cushion angles were 8° were evaluated the most "high-class" and those seats whose angles were 15° were evaluated the most "sporty". Further a pressure and a contact area distributions between the human body and the seat were measured by a tactile sensor system while sitting on seats whose cushion angles were 0, 8 or 15°. From the result of correlation analysis among the cushion angle, the pressure distribution and the sensory values of sitting comfort, it is found that the "sporty" and "hold" feeling increases as the cushion angle of the middle class car increases. The "support under the femoral region" feeling increases as the angle of the popular class car increases. And the "hold" feeling increases and the "comfortable" feeling decreases as the angle of the mini-sized car increases.
A sitting comfort of six automotive seats, whose covering fabric and cushion pad were changed, and shape and structure of seats were the same, was evaluated by only tactile sensation while sitting on these seats. The adjectives used for the sensory evaluation of seat comfort by the human tactile sensation were examined by the factor analysis. As the result of factor analysis, the sitting comfort of driver's seats was evaluated by two adjectives "soft" and "sliding". From the correlations among physical properties of fabrics and pad, the pressure distribution and sensory evaluations for seat, it is found that the "soft" feeling has a correlation with the contact area and pressure at buttocks and the physical property of pad, and that the "sliding" feeling has a correlation with the friction coefficient of covering fabric.
