Abstract

Impact of Seat and Back Angle Settings on Seating Furniture Quality: An Experimental Study. The fundamental measure of the quality of seating furniture is seating comfort. Sitting comfort is described in the literature by the discomfort coefficient D, calculated from the pressure values and distribution measured between the human body and a sitting furniture "body support system". The work aims to experimentally verify the influence of selected anthropometric features on sitting comfort. The research was carried out on 12 people using a piezoelectric sensor mat and a model of adjustable sitting furniture. The study investigated how different seat and backrest inclination variants impact pressure distribution. The test results are the values of the contact pressures and discomfort coefficients D for nine combinations of the backrest and seat inclination related to the anthropometric characteristics of the tested group of people. The results indicate that anthropometric factors, such as body mass index (BMI) and user gender, significantly impact objective seating comfort. These findingswill help optimize the seating furniture dimensions at their design stage

座椅和靠背角度设置对座椅家具质量影响的实验研究

座椅和靠背角度设置对座椅家具质量影响的实验研究。座椅家具质量的根本衡量标准是座椅舒适性。坐着的舒适度在文献中用不适系数D来描述，不适系数D是根据人体与坐式家具“身体支撑系统”之间测量的压力值和分布来计算的。本研究旨在通过实验验证选定的人体测量特征对坐姿舒适度的影响。这项研究是在12个人身上进行的，他们使用压电传感器垫和可调节坐式家具模型。研究了不同的座椅和靠背倾角对压力分布的影响。测试结果是与测试人群的人体测量特征相关的靠背和座椅倾角的九种组合的接触压力和不适系数D的值。结果表明，人体测量因素，如身体质量指数(BMI)和用户性别，显著影响客观座椅舒适度。这些发现将有助于在设计阶段优化座椅家具的尺寸
