The dimensional seat design process should consider both the users' tasks and their physical characteristics.
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.
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.
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.
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.
多维座椅设计过程应同时考虑用户的任务和他们的身体特征。
根据伊朗人口的人体测量特征和拖拉机操作人员的要求，采用一种设计和评估座椅尺寸的方法。
根据逻辑推理和国际标准，对与座椅尺寸相关的一些现有方程进行了修改。采用新的数理统计方法，根据理论上最大限度地提高适应性水平，提取估计恒定位尺寸的方程。此外，开发了总体座椅适应性评分（OSAS），以同时表示座椅尺寸适应性水平和尺寸适应性平等的平均值。
在可调节性、美观和空间限制等不同条件下，座椅的尺寸设计可能会受到影响。然而，结果表明，在不显著增加最终成本和复杂性的情况下，改进拖拉机座椅的设计是可能的。
为伊朗操作人员样本使用了一种新的拖拉机座椅设计方法，也可用于为其他目标人群设计和评估拖拉机座椅。
