Designing one seat for multi-sitters and multi-activities is challenging especially in a very restrained aircraft economy class cabin. In this paper, the effects of seat parameters and sitters' anthropometric dimensions on seat profile and optimal compressed seat pan surface were studied using a newly built multi-adjustable experimental seat. The 'optimal' seat pan contact surface was obtained by controlling the height of 52 cylinders so that the normal contact force was distributed to all cylinders as evenly as possible. With 13 other motorized adjustments controllable by a computer, individual seat profile in the symmetry plane such as seat height, seat pan length, seat pan angle, lumbar protrusion and headrest position were also studied. Data were collected from 36 men and women of varying body size testing 40 seat configurations. Parametric models were obtained for predicting seat profile and optimal compressed seat pan seat surface in function of seat pan and back rest angles for two sitting postures. It is expected that the proposed parametric models provide necessary reference values in seat development for a better fit of a target population of sitters with large varying body size.
为多位乘客和多种活动设计一个座位是具有挑战性的，特别是在空间有限的飞机经济舱内。本文使用新构建的多调节实验座椅，研究了座椅参数和乘客人体尺寸对座椅轮廓和最佳压缩座垫表面的影响。通过控制 52 个圆柱的高度，使正常接触力尽可能均匀地分布到所有圆柱上，从而获得“最佳”座垫接触表面。通过计算机控制另外 13 个可电动调节的功能，还研究了对称平面中的各个座椅轮廓，如座椅高度、座垫长度、座垫角度、腰椎突出和头枕位置。从 36 名男女乘客中收集了不同体型的测试数据，共测试了 40 种座椅配置。为了预测两种坐姿下座椅轮廓和最佳压缩座垫表面，建立了座垫和靠背角度的参数模型。预计所提出的参数模型为座椅开发提供了必要的参考值，以便更好地适应具有较大体型差异的目标乘客群体。
