In recent years, the equip ratio of SRS air bag system in new cars is increasing. Technology of SRS air bag system has been developed and it can be said that SRS air bag system can protect crews from impact in the car accident. In fact, the number of death and serious accident has been decreased by SRS air bag. Bat it is reported that crews got some abrasion on their faces and heads when they touched the opened SRS air bag under collision.We presume that the frictional force between SRS air bag and crew causes the abrasion. In this study, we investigate frictional characteristic of SRS air bag materials under the impact load. To examine frictional characteristic of SRS air bag materials under the impact load, we constructed an impact test apparatus.We have referred to a typical pressure-time history of an airbag, and a device is developed to measure impact load when the fabric is inflating at high speed. When pressure in a airbag increases, impact load increases. Also, impact load given to a body becomes large as shortens spacing with the body and an airbag. Relation between indenting ratio and pressure ratio give a single for different sample and different experimental condition.

近年来，SRS安全气囊系统在新车中的装备比例越来越高。SRS安全气囊系统的技术已经得到了发展，可以说SRS安全气囊系统可以在汽车事故中保护乘员免受冲击。事实上，SRS安全气囊已经减少了死亡和严重事故的数量。但据报道，机组人员在碰撞中接触到打开的SRS安全气囊时，面部和头部都有擦伤。我们推测是SRS气囊和机组人员之间的摩擦力造成了磨损。在本研究中，我们研究了SRS安全气囊材料在冲击载荷下的摩擦特性。为研究SRS气囊材料在冲击载荷作用下的摩擦特性，搭建了冲击试验装置。我们参考了一个典型的安全气囊的压力-时间历史，并开发了一个装置来测量织物在高速充气时的冲击载荷。当安全气囊中的压力增加时，冲击载荷也会增加。此外，随着车身与安全气囊之间的间距缩短，车身承受的冲击载荷也会变大。给出了不同样品和不同实验条件下压痕比与压痕比的关系。
