坐姿对办公椅座面体压分布及特征指标的影响
Effect of sitting posture on the pressure distribution and characteristic indexes of office chair seat
摘要
Abstract
The impact of sitting posture on comfort is crucial.To study the influence of various sitting postures on seat pressure in office chairs and explore how different sitting postures support various groups of people,the most commonly used office chairs were identified through online research.Based on the survey results,three experimental office chairs were selected for this study.The seated body pressure data of 22 subjects with different body types were measured in the forward sitting,upright seating and backward sitting positions.The resulting 198 body pressure data were imported into Matlab software for analysis.Metrics such as mean pressure,maximum pressure,contact area,mean pressure gradient,maximum pressure gradient,pressure index,and percent area index(%PAI)were calculated and analyzed.The results showed that there were significant differences between the seat pressures in different sitting positions.The reclining sitting position had the best support effect on the human body and upright seating was the worst.The percentage of contact area with high pressure threshold on the seat surface was the largest in the obese body type under the forward sitting position.The percentage of contact area with high pressure threshold on the seat surface was the highest in the middle-sized population under the upright sitting position.Therefore,the support effect of the seat face was the worst for the obese people in the forward sitting and was the worst for the middle-sized people in upright seating.The same sitting position provided better support effect for females.For women,the percentage of high-pressure threshold contact area was the largest in the forward sitting position,whereas for men,it was the largest in the upright sitting position.This indicated that the seat provided the worst support for women in the forward sitting position and the worst support for men in the upright sitting position.The research results can be used to evaluate the support of office chair seats and offer a basis for different office groups to choose a healthy sitting posture.关键词
