Analysis of Typical Defects in SRS by Taking the Recall Cases as Examples

Abstract

With the development of highways and the improvement in vehicle performance, vehicle speed has become faster and faster, causing more and more frequent accidents. As an auxiliary configuration of vehicle body’s passive safety, SRS (supplemental inflatable restraint system) often serves as a key component providing protection for both the driver and passengers and thus receives increasing attention. By taking the latest recall case base in 2012 and 2013 as a blue print, this paper analyzes 111 SRS-caused recalls implemented by China, the US, the EU and Australia respectively, discusses main defect forms of SRS, and finally proposes the improvement suggestions on safety techniques in design and manufacturing.
