This paper aimed to identify the reach capabilities of 26 seated subjects considering the reach difficulty, orientation and other potential factors, and to find a method to model the minimum reach capability surfaces for fixed and adjustable seats. The reach capability radius was used as a measure of the reach capability and theoretically modeled. Based on the test data of seated reach, the distribution of the reach capability radius was analyzed. The strategy to select the minimum reach envelopes was constructed to accommodate a sufficient percentage of the target population for both fixed and adjustable seats. For adjustable seats, a method was developed to derive the reach capability data from the tested individual reach capability data by introducing seating position models to re-position the individual reach capability data. An application case was realized based on the cab packaging data of a mini-van, and the minimum reach envelopes of different difficulties were created and validated to accommodate 90% of the target population.
本文旨在考虑伸展难度、方向及其他潜在因素，确定26名坐姿受试者的伸展能力，并找到一种为固定座椅和可调节座椅建立最小伸展能力表面模型的方法。伸展能力半径被用作伸展能力的度量并进行了理论建模。基于坐姿伸展的测试数据，分析了伸展能力半径的分布。构建了选择最小伸展包络的策略，以适应固定座椅和可调节座椅目标人群的足够比例。对于可调节座椅，通过引入座位位置模型重新定位个体伸展能力数据，开发了一种从测试的个体伸展能力数据中导出伸展能力数据的方法。基于一辆小型货车的驾驶室包装数据实现了一个应用案例，创建并验证了不同难度的最小伸展包络，以适应90%的目标人群。
