    • A module cover mounting structure for an air bag device for a passenger, is formed of an opening formed in the instrument panel of an automobile for mounting the air bag device, a module cover for covering the opening such that its peripheral edge covers the edge of the opening inside of the cabin of the automobile, and a plurality of tear lines formed in the module cover and adapted to be torn by the push of said air bag, when the air bag is inflated. The central portion of the module cover is torn into a door shape to be opened into the cabin. The tear lines are composed of a lefthand tear line running along the side of said module cover at the lefthand side of the automobile and a righthand tear line running along the side at the righthand side of the automobile. The lefthand and righthand tear lines run up to the edge of the module cover at the back side of the automobile.
    • 用于乘客的气囊装置的模块盖安装结构由形成在用于安装气囊装置的汽车的仪表板中的开口形成,模块盖用于覆盖开口,使得其周边覆盖 汽车舱内的开口,以及形成在模块盖中的多个撕裂线,并且当气囊膨胀时,通过推动气囊而被撕裂。 模块盖的中央部分被撕成门形,打开进入机舱。 撕裂线由沿着汽车左侧的模块盖侧面延伸的左脚撕裂线和沿着汽车右侧一侧延伸的右侧撕裂线构成。 左手和右手的撕裂线在汽车背面延伸到模块盖的边缘。
