侧面安全气囊展开的伤害风险已经使用静止的离位乘员测试协议进行了评估。然而，静止条件可能并不总是代表真实的世界环境。因此，本研究的目的是评估躯干侧气囊展开对近距离乘员的影响，比较静态测试协议与动态雪橇条件。胸部压缩和粘性指标量化雪橇测试，利用死后人体标本和计算模拟与三个边界条件：刚性壁，理想的安全气囊相互作用，近距离安全气囊部署。从胸带轮廓重建中量化PMHS指标。利用计算模型研究了ΔV对近距离乘员的参数影响。PMHS损伤表明近距离乘员可能遭受内脏创伤，而在刚性壁或理想气囊边界条件下的乘员中未观察到内脏创伤。峰值伤害指标也升高与近距离乘员相对于其他边界条件。计算模型表明，随着ΔV的增加，安全气囊对压缩度量的影响减小。当ΔV = 7.0 m/s时，气囊对粘性指标的影响最大，此时的响应幅度大于刚性碰撞和静止近距离相互作用所产生的指标的线性总和。这些结果表明，静止的近距离乘员可能并不代表侧气囊展开对胸腹区域有害的唯一情况。粘性度量的敏感性和内脏创伤的影响也进行了讨论。
Injury risk from side airbag deployment has been assessed using stationary out-of-position occupant test protocols. However, stationary conditions may not always represent real world environments. Therefore, the objective of the present study was to evaluate the effects of torso side airbag deployment on close-proximity occupants, comparing a stationary test protocol with dynamic sled conditions. Chest compression and viscous metrics were quantified from sled tests utilizing post-mortem human specimens and computational simulations with three boundary conditions: rigid wall, ideal airbag interaction, and close-proximity airbag deployment. PMHS metrics were quantified from chestband contour reconstructions. The parametric effect of ΔV on close-proximity occupant was examined with the computational model. PMHS injuries suggested close-proximity occupants may sustain visceral trauma, which was not observed in occupants subjected to rigid wall or ideal airbag boundary conditions. Peak injury metrics were also elevated with close-proximity occupant relative to other boundary conditions. The computational model indicated decreasing influence of airbag on compression metrics with increasing ΔV. Airbag influence on viscous metric was greatest with close-proximity occupant at ΔV = 7.0 m/s, at which the response magnitude was greater than linear summation of metrics resulting from rigid impact and stationary close-proximity interaction. These results suggest that stationary close-proximity occupants may not represent the only scenario of side airbag deployment harmful to the thoracoabdominal region. The sensitivity of the viscous metric and implications for visceral trauma are also discussed.
