本文件总结了负责确定暴露于全身振动的坐着人员的姿势的人员（如科学家、安全工程师）的描述性量。目的是不同方法的结果可以很容易地与这些量相关联，并且它们允许从业者之间的通用术语。本文档的重点是提供一系列关于如何在实践中测量姿势的想法。确定的姿势也可以用作进一步研究的基础或不同方法的比较手段。虽然这里描述的一些方法可以应用于站立或躺卧位置，但是在这些情况下可能需要额外的考虑。 笔记？1？这项工作与关注静态姿势的国际标准（ISO？11226[4]）或放射学上可接近的地标，即。e.身体上的点（ISO？8727[3]）. 此外，本文档涉及动态姿势，其中身体角度或相关运动通过视觉或通过测量皮肤或衣服上的点来确定。 笔记？2？尽管如此，ISO？8727[3]和ISO？11226[4]提出了本文件中遵循的姿势确定的进一步扩展的原理，特别是用于身体角度的测量。 本文件未指定抽样策略或评估方法。

This document summarizes descriptive quantities for those responsible (e.g. scientists, safety engineers) for determination of postures for a seated person who is exposed to whole-body vibration. It is the intention that the results of different methods can be easily related to these quantities and that they allow for a common terminology between practitioners. The focus of this document is to offer a collection of ideas on how to measure postures in practice. The postures determined can also be used as a basis for further investigation or as a means of comparison for different methods. Although some of the approaches described here can be applied to standing or recumbent positions, additional considerations are likely to be required in these cases. NOTE？1？This work is closely related to International Standards which focus on static postures (ISO？11226^[4]) or on radiologically accessible landmarks, i.e. points on the body (ISO？8727^[3]). Additionally, this document deals with dynamic postures where body angles or associated movements are determined visually or by measuring points on the skin or clothing. NOTE？2？Nevertheless, ISO？8727^[3] and ISO？11226^[4] put forward principles for further extensions of posture determination which are followed in this document, in particular for measurements of body angles. This document does not specify sampling strategies or evaluation methods.
