    • A vehicle air bag apparatus which includes an air bag module having an air bag, an inflator for filling the air bag with gas and an ignitor for driving the inflator. The vehicle air bag apparatus is supported inside of an opening formed in an instrument panel of a vehicle. The vehicle air bag apparatus also includes an air bag lid for closing the opening during non-operating status of the vehicle air bag apparatus, a hinge member for supporting the air bag lid openably and closeably in correspondence to the opening in the instrument panel, and a projection member formed integrally with the rear surface of the air bag lid. The projection member extends toward, and is fixed to, the air bag module. The projection member holds the air bag lid so as to close the opening and reinforces the air bag lid from the rear surface. The projection member includes portions of lower ridigity in which rigidity of a part furthest from the hinge member is the lowest. Upon expansion of the air bag, the portions of lower rigidity break so that the air bag lid no longer acts to close the opening in the instrument panel.
    • 一种车用气囊装置,包括具有气囊的气囊模块,用于用气体填充气囊的充气机和用于驱动充气机的点火器。 车辆安全气囊装置被支撑在形成在车辆的仪表板上的开口的内部。 车用气囊装置还包括用于在车辆气囊装置的非操作状态期间关闭开口的气囊盖,用于相对于仪表板的开口可开启地并且可靠地支撑气囊盖的铰链构件,以及 与气囊盖的后表面整体形成的突出部件。 突出构件向气囊模块延伸并固定在气囊模块上。 突起构件保持气囊盖以便关闭开口并且从后表面加强气囊盖。 突起构件包括下部倾斜部分,其中最远离铰链构件的部分的刚度最低。 在气囊膨胀时,刚性较低的部分断裂,使得气囊盖不再起作用以关闭仪表板中的开口。
