Abstract

BACKGROUND: The dimensional seat design process should consider both the users’ tasks and their physical characteristics. OBJECTIVE: To use an approach for the design and evaluation of seat dimensions based on the anthropometric characteristics of the Iranian population and the requirements of tractor operators. METHODS: Some existing equations relating the seat dimensions to anthropometric characteristics were modified according to logical justifications and international standards. A new mathematical-statistical method was used to extract the equations estimating the constant seat dimensions based on the theoretical maximizing of the accommodation level. In addition, an Overall Seat Accommodation Score (OSAS) was developed to represent the mean of seat dimensions accommodation level and dimensional accommodation equality, simultaneously. RESULTS: The dimensional seat design can be affected under different conditions of adjustability, esthetic, and space limitations. However, it was shown that it is possible to improve the design of tractor seats without any significant increase in the final cost and complexity. CONCLUSION: A new approach was used for tractor seats for a sample of Iranian operators and can be used for the design and evaluation of tractor seats for other target populations.

基于伊朗人体测量特征的拖拉机座椅尺寸设计

背景：座椅的尺寸设计过程应同时考虑使用者的任务和他们的身体特征。目标：根据伊朗人口的人体测量特征和拖拉机驾驶员的要求，使用一种方法来设计和评估座椅尺寸。方法：根据逻辑依据和国际标准，对现有的一些与人体测量特征相关的座椅尺寸公式进行修改。我们采用了一种新的数学统计方法，根据理论上最大化的舒适度，提取出估算恒定座椅尺寸的方程。此外，还开发了座椅舒适度总分（OSAS），以同时表示座椅尺寸舒适度水平和尺寸舒适度平等的平均值。结果：在可调节、美观和空间限制等不同条件下，座椅的尺寸设计会受到影响。然而，研究表明，在不显著增加最终成本和复杂性的情况下，改进牵引座椅的设计是可能的。结论：针对伊朗操作员样本的拖拉机座椅采用了一种新方法，可用于设计和评估其他目标人群的拖拉机座椅。
