The invention discloses a blasting weakening structure of an automobile front passenger seat airbag. The weakening structure is rectangular, is arranged on a dashboard body and comprises a hinge sideweakening line, an airbag opening side weakening line and two oppositely arranged protection side weakening lines, wherein the hinge side weakening line and the airbag opening side weakening line areoppositely arranged, the strength of the hinge side weakening line is higher than that of the protection side weakening line, and the strength of the protection side weakening lines is higher than that of the airbag opening side weakening line. According to the weakening structure, the four weakening lines are provided with weakening holes, by adjusting the size, depth and arrangement of the weakening holes, the weakening structure can be broken from the four weakening lines and turned over along with the hinge after the airbag is exploded, fragments cannot be formed, and the safety performance is high.
本发明公开了一种汽车副驾驶安全气囊爆破弱化结构,弱化结构为矩形,设置于仪表板本体上,包括相对设置的铰链侧弱化线和气囊开启侧弱化线,以及两条相对设置的保护侧弱化线,铰链侧弱化线的强度高于保护侧弱化线,保护侧弱化线的强度高于气囊开启侧弱化线。四条弱化线上设置有弱化孔,通过调整弱化孔的大小、深度及其排布,使本发明弱化结构能在发生撞击安全气囊爆开后从四条弱化线处断裂,随铰链一起翻转,不会形成碎片,安全性能高。
