如果头盔在佩戴者的头部上配合不良，则头盔的安全益处降低。目前，没有行业标准可用于客观评估特定的防护头盔如何适合特定的人。适当的贴合性通常被定义为头盔衬里与佩戴者的头部形状之间的小且均匀的距离，具有头部区域的广泛覆盖范围。本文提出了一种新的方法来调查和比较头盔的拟合精度的基础上三维人体测量，逆向工程技术和计算分析。头盔适配指数（HFI），提供了一个从0（非常差的适合）到100（完美的适合）的规模适合分数进行了比较，与主观的适合评估的调查骑自行车。本研究的结果表明，在比较三种市售自行车头盔时，定量（HFI）和定性（参与者的感受）数据是相关的。研究结果还表明，女性和亚洲人的契合度得分分别低于男性和白人。HFI可以提供关于适合的头盔效率的详细理解，并且可以在头盔设计和开发阶段期间使用。(C)2016年爱思唯尔有限公司和人体工程学协会。All rights reserved.
Helmet safety benefits are reduced if the headgear is poorly fitted on the wearer's head. At present, there are no industry standards available to assess objectively how a specific protective helmet fits a particular person. A proper fit is typically defined as a small and uniform distance between the helmet liner and the wearer's head shape, with a broad coverage of the head area. This paper presents a novel method to investigate and compare fitting accuracy of helmets based on 3D anthropometry, reverse engineering techniques and computational analysis. The Helmet Fit Index (HFI) that provides a fit score on a scale from 0 (excessively poor fit) to 100 (perfect fit) was compared with subjective fit assessments of surveyed cyclists. Results in this study showed that quantitative (HFI) and qualitative (participants' feelings) data were related when comparing three commercially available bicycle helmets. Findings also demonstrated that females and Asian people have lower fit scores than males and Caucasians, respectively. The HFI could provide detailed understanding of helmet efficiency regarding fit and could be used during helmet design and development phases. (C) 2016 Elsevier Ltd and The Ergonomics Society.
