Previous studies indicate that seatbelts may require supplementary restraints to increase their effectiveness in far-side impacts. This study aimed to evaluate the effectiveness of a novel, far-side-specific airbag in restraining and preventing injuries in far-side impacts, and to evaluate the WorldSID's response to the presence of a far-side airbag. A series of tests with three Post-Mortem Human Subjects and the WorldSID was conducted in a vehicle-based sled environment equipped with a far-side airbag. Results of these tests were evaluated and compared to a previous test series conducted without the airbag. All of the PMHS retained the shoulder belt on the shoulder. The airbag significantly reduced PMHS injury severity and maximum lateral head excursion. While the WorldSID exhibited a similar decrease in lateral excursion, it was unable to represent PMHS thoracic deflection or injury probability, and it consistently slipped out of the shoulder belt. This indicates that the WorldSID is limited both in its ability to evaluate the effect of changes in the seatbelt system and in its ability to predict thoracic injury risk and assess airbag-related injury mitigation countermeasures.
先前的研究表明，安全带可能需要额外的约束装置来提高其在侧面碰撞中的有效性。本研究旨在评估新型侧面专用安全气囊在限制和防止侧面碰撞中受伤的有效性，并评估 WorldSID 对侧面安全气囊存在的反应。在配备侧面安全气囊的车辆 sled 环境中，对三个死后人体模型和 WorldSID 进行了一系列测试。对这些测试的结果进行了评估，并与没有安全气囊的先前测试系列进行了比较。所有 PMHS 都保持在肩部的肩带。安全气囊显著降低了 PMHS 伤害严重程度和最大侧向头部偏移。虽然 WorldSID 表现出相似的横向偏移减小，但它无法代表 PMHS 胸部偏转或伤害概率，并且它始终从肩带中滑出。这表明，WorldSID 既限制了其评估安全带系统变化效果的能力，也限制了其预测胸部受伤风险和评估安全气囊相关伤害缓解对策的能力。
