| Body pressure distribution is widely used in so many area that the design of the seat is also involved. It is currently used in car seat design, that experimental study by body pressure distribution about the human body in a vehicle to maintain a healthy posture approach was depth. In addition, the rich variety of forms means endless of seat design, however, research about the comfort on the human body needs especially hip is very few mentioned. The paper starting from the body pressure distribution experiments, and using a new method to achieve the needs of human hip's comfort by inflexible seat design. Body pressure distribution test on inflexible seat and the sofa as a starting point, the 30 subjects who did experiments related to body pressure distribution and the subjective questionnaire, by comparison, sofa is better meet the position of comfort needs in the process of exploring,the reasons for that, parts of the body force and the satisfaction of people's subjective comfort have a direct link, through the only contact method, which maintain the body only when the hip and the seat face contacting to measure the body contact pressure distribution of the hip, and assisted by the relevant questionnaire, found that under both seats, maintaining the same body posture to bring the only difference is the hip's pressure distribution, which shows the demand for comfort and body pressure distribution have direct relevance, the paper breakthrough by the body pressure distribution data to complete a inflexible seat design to meet the needs of human buttocks comfort.Test through the body pressure distribution on the human body and the inflexible seat surface contact pressure distribution, the test data recorded by Xsensor software, in the Microsoft Vision C++6.0 environment, Programmed a data processing computer to program the TXT file exported from Xsensor to convert it into a text format that Rhinoceros can be imported in. Analysis of the distribution points, processing point data generated by the surface Rhinoceros command will generate a valid data surface, the curved surface similar to human buttocks that can expand human buttocks and seat contact area. By using the design and implementation of inflexible seat surface to achieve the application of pressure distribution, the seat surface totally used body pressure distribution data surface, then the dispersion of the human body can be better and avoid excessive local pressure discomfort caused to the human body to meet the needs of human hip's comfort. |
