    • A break-away fastening system for securing an air bag deployment door in position closing a panel opening used for air bag deployment includes a fastener extending from the door toward a facing edge flange of the panel around the panel opening. The fastener includes a head at an end portion directed toward the edge flange and adapted to be inserted through an aperture provided therein as the door is moved into place covering the panel opening. After full insertion, fingers of the head snap outwardly away from each other on an opposite side of the edge flange to lock the head and thus secure the door firmly in place. The fastener has at least one frangible section of reduced cross-section between the door and the edge flange which section is fractured or broken upon deployment of the air bag against the door as it moves through the panel opening.
    • 用于将气囊展开门固定的位置的分离紧固系统用于关闭用于安全气囊展开的面板开口的紧固系统包括从门朝向面板开口周围的面向面向边缘凸缘延伸的紧固件。 紧固件包括在端部处的朝向边缘凸缘的头部,并且当门移动到覆盖面板开口的位置时,该头部适于插入穿过设置在其中的孔。 在完全插入之后,头部的指状物在边缘凸缘的相对侧上彼此相对地向外相互锁定,从而将门牢固地固定在适当的位置。 紧固件在门和边缘凸缘之间具有至少一个具有减小的横截面的易碎部分,该部分在通过面板开口移动时,将气囊抵靠门部署时,该部分断裂或断裂。
