Abstract

Seat dimensions that influence human comfort are not independent. To improve the combined effect of the multiple-seat-dimension design, the correlations of key seat dimensions were analyzed. First, a structural-equation model was used to explore and test the relationships and influence path between the seat dimensions. Then, multiple regression analysis was used to explore the quantitative relationships between the seat dimensions. The results showed that the seat pan inclination, backrest inclination, and seat height are interrelated to form the seat support angle, which determines the human torso–thigh–calf angles in a sitting position and affects the dimension requirements of the lumbar and neck support. The study further proposes a quantitative model relating the key seat dimensions. Research has shown that comfortable seat dimension design cannot rely solely on the design of a single independent seat dimension but requires a unified design of multiple-seat dimensions. This study provides the quantitative relationships between comfortable seat dimensions for key seat-dimension-correlated design, which will help predict the comfortable dimension and improve dimension design comfort.

舒适性座椅尺寸：相关性和设计方法

影响人体舒适度的座椅尺寸并不是独立的。为了提高多座椅维度设计的综合效果，我们对主要座椅维度的相关性进行了分析。首先，使用结构方程模型来探索和检验座椅各维度之间的关系和影响路径。然后，使用多元回归分析来探索座椅尺寸之间的定量关系。结果表明，座椅面板倾斜度、靠背倾斜度和座椅高度相互关联，形成座椅支撑角度，而座椅支撑角度决定了人体坐姿下的躯干-大腿-小腿角度，并影响腰部和颈部支撑的尺寸要求。该研究进一步提出了一个与关键座椅尺寸相关的定量模型。研究表明，舒适座椅的尺寸设计不能仅仅依靠单一独立座椅尺寸的设计，而是需要多个座椅尺寸的统一设计。本研究为关键座椅维度相关设计提供了舒适座椅维度之间的定量关系，这将有助于预测舒适维度，提高维度设计的舒适性。

期刊介绍： The purpose of Human Factors and Ergonomics in Manufacturing & Service Industries is to facilitate discovery, integration, and application of scientific knowledge about human aspects of manufacturing, and to provide a forum for worldwide dissemination of such knowledge for its application and benefit to manufacturing industries. The journal covers a broad spectrum of ergonomics and human factors issues with a focus on the design, operation and management of contemporary manufacturing systems, both in the shop floor and office environments, in the quest for manufacturing agility, i.e. enhancement and integration of human skills with hardware performance for improved market competitiveness, management of change, product and process quality, and human-system reliability. The inter- and cross-disciplinary nature of the journal allows for a wide scope of issues relevant to manufacturing system design and engineering, human resource management, social, organizational, safety, and health issues. Examples of specific subject areas of interest include: implementation of advanced manufacturing technology, human aspects of computer-aided design and engineering, work design, compensation and appraisal, selection training and education, labor-management relations, agile manufacturing and virtual companies, human factors in total quality management, prevention of work-related musculoskeletal disorders, ergonomics of workplace, equipment and tool design, ergonomics programs, guides and standards for industry, automation safety and robot systems, human skills development and knowledge enhancing technologies, reliability, and safety and worker health issues.
