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配备比例不断增加。 SRS安全气囊系统的技术已经开发出来，可以说SRS安全气囊系统可以在车祸中保护乘员免受冲击。事实上，SRS 气囊已经减少了死亡和严重事故的数量。据报道，碰撞时，乘员在接触打开的SRS气囊时，脸部和头部出现了一些擦伤。我们推测是SRS气囊与乘员之间的摩擦力造成了擦伤。在本研究中，我们研究了 SRS 气囊材料在冲击载荷下的摩擦特性。为了检查 SRS 气囊材料在冲击载荷下的摩擦特性，我们构建了冲击测试装置。我们参考了气囊的典型压力-时间历史，开发了一种装置来测量织物在高速。当安全气囊中的压力增加时，冲击载荷增加。另外，随着车身与气囊之间的距离变短，给予车身的冲击载荷也变大。压痕比和压力比之间的关系给出了针对不同样品和不同实验条件的单一结果。
