摘 要:副驾驶安全气囊、驾驶侧安全气囊和安全带等被动安全装置可以降低正面碰撞中乘员头部及胸部的伤害,但对乘员的腿部保护效果有限,因此膝部安全气囊的需求与应用越来越多。基于此,研究小组分析了某乘用皮卡膝部安全气囊一些设计要点,包括膝部安全气囊与周边件,如地毯、仪表板的匹配要求,为保证膝部安全气囊能顺利展开,剖析了膝部安全气囊常见的撕裂线形式及相关参数常用的设计值,以及膝部安全气囊的布置要求等,同时阐述了膝部安全气囊静态展开试验时的试验标准、试验条件、试验合格的判断依据,为后续膝部安全气囊的设计开发提供参考。仿真结果表明,膝部安全气囊是汽车被动安全的重要组成部分,可在汽车发生碰撞时与副驾驶安全气囊、侧气帘等一起保护车内乘员免受伤害。

Abstract: Passive safety devices such as passenger airbags, driver side airbags, and seat belts can reduce head and chest injuries in frontal collisions, but their leg protection effect is limited. Therefore, there is an increasing demand and application for knee airbags. Based on this, the research team analyzed some key design points of the knee airbag of a passenger pickup truck, including the matching requirements of the knee airbag and peripheral parts, such as carpet and instrument panel. In order to ensure the smooth deployment of the knee airbag, it analyzed the common tear line forms of the knee airbag and the common design values of relevant parameters, as well as the layout requirements of the knee airbag. At the same time, the test standards, test conditions and the judgment basis of the test qualification during the static deployment test of the knee airbag are described, providing a reference for the design and development of the knee airbag in the future. The simulation results show that the knee airbag is an important part of the passive safety of the vehicle, which can protect the passengers in the vehicle from injury together with the passenger airbag and side airbag curtain in case of collision.
Keywords: knee airbag; tear line; deployment test; instrument panel
