Design of Automotive Seat Surface Based on Ergonomics

Based on ergonomics theory, the paper analyzes the influencing factors of automobile driving comfort, from two sides, that are, physiological form of human sitting posture and body press distribution. On this basis, human physiological curve, the pressure curve and their function expressions are fitted through mathematical software. And combining the seat material properties, the seat curve in line with the human ecology is deduced, which provides new ideas for the seat design. Finally, this paper identifies H-point and draws the mating graph of seat surface curves and dummy.
