    • An air bag cover for covering an air bag in a folded state, the air bag being adapted to expand in front of a seat occupant at a sudden deceleration of the vehicle speed. The air bag cover includes a first thin-wall portion which is first broken by the expanding pressure at the time of the inflation of the air bag and a second thin-wall portion which is broken after the breakage of the first thin-walled portion has advanced. The first thin-walled portion and the second thin-walled portion are connected to each other in such a manner as to be substantially perpendicular to each other. A connecting portion between the two thin-walled portions has an even smaller thickness than the thicknesses of the two thin-walled portions, thereby permitting the breakage of the first thin-walled portion to advance smoothly to the second thin-walled portion.
    • 一种用于在折叠状态下覆盖气囊的气囊盖,所述气囊适于在车速的突然减速时在座椅乘员的前方扩张。 气囊盖包括第一薄壁部分,该第一薄壁部分首先被气囊膨胀时的膨胀压力破坏,并且在第一薄壁部分破裂之后破裂的第二薄壁部分具有 高级。 第一薄壁部分和第二薄壁部分以彼此基本垂直的方式彼此连接。 两个薄壁部分之间的连接部分具有比两个薄壁部分的厚度更小的厚度,从而允许第一薄壁部分的断裂顺利地前进到第二薄壁部分。
