This paper provides the results from an experimental study intended to assess airbag impact to the orbit. Twenty-seven airbags were deployed onto an instrumented Hybrid III headform. Seven different types of airbags were used that included tethered and nontethered, light to heavy nylon weaves, and different coating types. The airbags were deployed via a pneumatic deployment system. Seven individual force transducers, each having a 2.25 cm2 contact area, were placed on the right orbital region to evaluate the force patterns. The midpoint of the two ocular regions of the headform was positioned 12.5 cm above and 15.0 cm away from the center of the airbag, a position determined from previous airbag deployments to yield the highest leading edge velocity. The average maximum force per sensor ranged from 15.4 N to 63.6 N, and peak pressure ranged from 68 kPa to 282 kPa. The upper center of the orbit presented the highest values while the center of the orbit recorded the lowest values, a comparison that was proven to be statistically significant. For this configuration, the maximum force on the ocular region was found to be independent of the presence of a tether or the maximum internal airbag pressure.
本文提供了一项旨在评估安全气囊对眼眶影响的实验研究结果。将27个安全气囊部署到装有仪器的Hybrid III型头模上。使用了七种不同类型的安全气囊，包括有系绳和无系绳的、从轻到重的尼龙编织物以及不同的涂层类型。安全气囊通过气动展开系统展开。七个单独的力传感器，每个传感器的接触面积为2.25平方厘米，放置在右眼眶区域以评估力的模式。头模两个眼部区域的中点位于安全气囊中心上方12.5厘米处且距其15.0厘米远，该位置是根据先前的安全气囊展开情况确定的，以产生最高的前缘速度。每个传感器的平均最大力范围为15.4牛至63.6牛，峰值压力范围为68千帕至282千帕。眼眶上部中心呈现出最高值，而眼眶中心记录到最低值，经证明这种比较具有统计学意义。对于这种配置，发现眼部区域的最大力与是否有系绳或安全气囊的最大内部压力无关。
