目的：很少有研究关注侧面碰撞时顶部系绳的有效性。在这些研究中，收集了有限的拟人试验装置（ATD）数据和/或观察到很少的侧面碰撞场景。本研究的目的是进一步了解ATD响应和儿童约束系统（CRS）的运动学在各种侧面impact conditions.Methods：一系列的高速近侧和远侧雪橇测试进行了使用FMVSS 213侧面碰撞雪橇巴克和Q3 s ATD的顶部系绳的影响。在相对于纯横向的10°和30°冲击下进行测试。两个儿童约束装置CRS A和CRS B使用柔性下锚固定在长凳上。在存在和不存在顶部系绳的情况下执行每个测试场景。仪器记录Q3 s响应和CRS运动学，和相同的测试场景，有和没有顶部系绳attachment进行了compared.Results：对于远侧侧向（10°）和倾斜（30°）的影响，顶部系绳附件增加了8-38%的头部加速度和头部损伤标准（15）值由20- 140%。然而，顶部系绳可有效减少5- 25%的侧向头偏移。对于近侧碰撞，顶部系绳导致头部加速度和侧向碰撞方向上的1500增加不到10%。对于近侧斜撞击，顶部系绳使CRS A的载荷增加了17.3%，CRS B的载荷减少了19.5%。然而，从这两种碰撞条件下确定的伤害值低于目前的伤害评估参考值（IARV）。此外，顶部系绳证明有利于防止向前和横向CRS rotations.Conclusions：结果表明，顶部系绳对Q3 s响应的影响取决于影响类型，影响角度，和CRS。与无系绳情况相比，系绳附件增加了头部加速度和15 ° C值，但头部偏移和CRS旋转的减少通常会抵消系绳附件的增加。
Objective: Few studies have looked at the effectiveness of the top tether during side impacts. In these studies, limited anthropomorphic test device (ATD) data were collected and/or few side impact scenarios were observed. The goal of this study was to further understand the effects of the top tether on ATD responses and child restraint system (CRS) kinematics during various side impact conditions.Methods: A series of high-speed near-side and far-side sled tests were performed using the FMVSS213 side impact sled buck and Q3s ATD. Tests were performed at both 10° and 30° impacts with respect to the pure lateral direction. Two child restraints, CRS A and CRS B, were attached to the bench using flexible lower anchors. Each test scenario was performed with the presence and absence of a top tether. Instrumentation recorded Q3s responses and CRS kinematics, and the identical test scenarios with and without a top tether attachment were compared.Results: For the far-side lateral (10°) and oblique (30°) impacts, top tether attachment increased resultant head accelerations by 8–38% and head injury criterion (HIC15) values by 20–140%. However, the top tether was effective in reducing lateral head excursion by 5–25%. For near-side impacts, the top tether resulted in less than 10% increases in both resultant head acceleration and HIC15in the lateral impact direction. For near-side oblique impacts, the top tether increased HIC15by 17.3% for CRS A and decreased it by 19.5% for CRS B. However, the injury values determined from both impact conditions were below current injury assessment reference values (IARVs). Additionally, the top tether proved beneficial in preventing forward and lateral CRS rotations.Conclusions: The results show that the effects of the top tether on Q3s responses were dependent on impact type, impact angle, and CRS. Tether attachments that increased head accelerations and HIC15values were generally counterbalanced by a reduction in head excursion and CRS rotation compared to nontethered scenarios.
