The risk of injury from torso side airbags in out-of-position (OOP) scenarios is assessed using stationary occupant conditions. Although stationary tests have been effective in frontal airbag assessments, their applicability to torso side airbags remains uncertain. Using the MADAYMO facet occupant model, thoracic OOP injury was evaluated using full-chest compression criteria (%C) and viscous criteria (VC) under stationary occupant conditions and occupant impact velocities of 6.0 m/s, 7.0 m/s, 8.0 m/s, and 9.0 m/s. During airbag deployment with a stationary occupant, peak %C = 21.8 % while peak VC = 0.86. At 6.0 m/s impact velocity, peak %C increased to 35.1 %; at 9.0 m/s impact velocity %C = 45.0 %. Similarly, peak VC increased from 1.19 at 6.0 m/s and to 1.96 at 9.0 m/s. These results demonstrated that thoracic injury metrics %C and VC increased in dynamic testing conditions. Therefore dynamic occupant tests may be required to effectively assess OOP thoracic injury risk.
使用静止的乘员条件评估在失位（OOP）情况下躯干侧面安全气囊造成伤害的风险。尽管静态测试在正面安全气囊评估中很有效，但其对躯干侧面安全气囊的适用性仍不确定。使用MADAYMO多面体乘员模型，在静止乘员条件以及6.0米/秒、7.0米/秒、8.0米/秒和9.0米/秒的乘员撞击速度下，使用全胸压缩标准（%C）和粘性标准（VC）评估胸部OOP损伤。在静止乘员的安全气囊展开过程中，峰值%C = 21.8%，而峰值VC = 0.86。在6.0米/秒的撞击速度下，峰值%C增加到35.1%；在9.0米/秒的撞击速度下，%C = 45.0%。同样，峰值VC从6.0米/秒时的1.19增加到9.0米/秒时的1.96。这些结果表明，在动态测试条件下，胸部损伤指标%C和VC会增加。因此，可能需要进行动态乘员测试以有效评估OOP胸部损伤风险。
