在这项研究中，调查了大约 7500 起造成人身伤害的追尾事故。统计数据取自“车辆安全 90”（VdS，1994），该数据库包含 1990 年德国（仅限旧州）发生的 15,000 起实际汽车事故，其中至少一名乘员受伤。从这些调查中，可以评估影响追尾碰撞中颈部受伤的几个因素。此外，还对一些选定的汽车座椅进行了志愿者的雪橇测试。测量并可视化乘员的头颈运动学。重复测试中尽可能选择相同的测试条件，以确保不同测试的公平比较。在 8 和 11 公里/小时的雪橇冲击速度下使用了九种不同的汽车座椅类型。雪橇平均减速度稳定在 2.5 g 水平。统计数据与测量结果的比较表明两种方法之间具有良好的相关性。因此，可以定义不同座椅在后端碰撞时颈部受伤风险的“排名”，并总结座椅结构中的最大问题。 (A) 有关会议的封面摘要，请参阅 IRRD E201282。
In this study approximately 7500 rear end impacts with personal injuries were investigated. The statistical data were taken from the "Vehicle Safety 90" (VdS, 1994), a database which contains 15,000 actual car to car accidents with at least one occupant injured in Germany (old states only) during 1990. From these investigations several factors which influence neck injuries in rear end collisions could be evaluated. In addition, sled tests with volunteers were performed for some selected car seats. The head-neck kinematics of the occupants was measured and visualized. Identical test conditions as far as possible have been chosen in repeated tests to ensure a fair comparison of the different tests. Nine different car seat types were used at sled impact velocities of 8 and 11 km/h. The mean sled decelerations were settled at a level of 2.5 g. The comparison of the statistics with the measurements showed a fair correlation between both approaches. So a "ranking" of the different seats regarding their risk of a neck injury during rear end impacts could be defined, and the biggest problems in seat construction could be summarized.
