    • An apparatus for deploying an air bag through an automotive dash panel includes an air bag door integrally formed in the panel and defined by a door perimeter including a frangible edge of reduced cross section. A dispenser supports the air bag behind the door. A metal reaction plate is positioned between the air bag and the door. When the air bag inflates, it forces the reaction plate to bend around a horizontal hinge line. As the reaction plate pivots it concentrates inflation force along a lower portion of the frangible door edge. This helps to predictably separate the door from the dash panel by tearing along the lower door edge and allowing the tear to propagate up two side edges. In one embodiment, the tear also propagates across an upper edge to completely separate the door from the panel. At least one, and preferably two or three tethers limit how far the door can travel during air bag inflation. A stop member may be included to limit reaction plate bending. After deployment, the reaction plate remains in a position that prevents the door from returning to its original position. A retaining structure may be included to preclude at least a portion of the air bag door from tearing free of the vehicle panel. A hinge may be embedded in the panel in a position spanning a portion of the door perimeter. A hollow channel may be formed into the panel along the frangible marginal edge to create a substantial strength differential with the door perimeter to promote bending along the hinge and/or to help confine tearing to the frangible marginal edge during air bag deployment.
    • 一种用于通过汽车仪表板部署气囊的装置包括一体地形成在面板中并由包括具有减小横截面的易碎边缘的门周边限定的气囊门。 分配器支持门后面的气囊。 金属反应板位于气囊和门之间。 当气囊膨胀时,它迫使反作用板围绕水平铰链线弯曲。 当反作用板枢转时,其沿着易碎门边缘的下部集中充气力。 这有助于通过沿下门边缘撕裂可预测地将门与仪表板分开,并允许撕裂沿两侧边缘传播。 在一个实施例中,撕裂也通过上边缘传播,以使门与面板完全分开。 至少一个,优选两个或三个系绳限制了在气囊充气期间车门能行进多远。 可以包括止动构件以限制反作用板弯曲。 在部署之后,反应板保持在防止门返回其原始位置的位置。 可以包括保持结构以排除气囊门的至少一部分不会脱离车辆面板。 铰链可以嵌入在面板中跨过门周边的一部分的位置。 中空通道可以沿易碎边缘形成到面板中,以产生与门周边相当的强度差异,以促进沿着铰链的弯曲和/或有助于限制在气囊展开期间的易碎边缘的撕裂。

    • An apparatus for deploying an air bag through an automotive dash panel (12) includes an air bag door (16) integrally formed in the panel and defined by a door perimeter including a frangible edge (18) of reduced cross section. A dispenser (20) supports the air bag (24) behind the door. A metal reaction plate (28) is positioned between the air bag (24) and the door (16). When the air bag inflates, it forces the reaction plate (28) to bend around a horizontal hinge line (36). As the reaction, plate pivots it concentrates inflation force along a lower portion of the frangible door edge. This helps to predictably separate the door from the dash panel by tearing along the lower door edge and allowing the tear to propagate up two side edges. In one embodiment, the tear also propagates across an upper edge to completely separate the door from the panel. At least one, and preferably two or three tethers (50) limit how far the door can travel during air bag inflation. A stop member may be included to limit reaction plate bending. After deployment, the reaction plate remains in a position that prevents the door from returning to its original position. A retaining structure may be included to preclude at least a portion of the air bag door from tearing free of the vehicle panel. A hinge (44) may be embedded in the panel in a position spanning a portion of the door perimeter. A hollow channel may be formed into the panel along the frangible marginal edge to create a substantial strength differential with the door perimeter to promote bending along the hinge and/or to help confine tearing to the frangible marginal edge during air bag deployment.
    • 一种用于通过汽车仪表板(12)展开气囊的装置包括一体地形成在面板中并由门周边限定的安全气囊门,该门周边包括具有减小横截面的易碎边缘(18)。 分配器(20)支撑门后面的气囊(24)。 金属反应板(28)位于气囊(24)和门(16)之间。 当气囊膨胀时,迫使反作用板(28)围绕水平铰接线(36)弯曲。 作为反应,板枢转,集中了易碎门边缘下部的充气力。 这有助于通过沿下门边缘撕裂可预测地将门与仪表板分开,并允许撕裂沿两侧边缘传播。 在一个实施例中,撕裂也通过上边缘传播,以使门与面板完全分开。 至少一个,优选两个或三个系绳(50)限制了门在气袋充气期间可以行进的距离。 可以包括止动构件以限制反作用板弯曲。 在部署之后,反应板保持在防止门返回其原始位置的位置。 可以包括保持结构以排除气囊门的至少一部分不会脱离车辆面板。 铰链(44)可以嵌入板中跨过门周边的一部分的位置。 中空通道可以沿着易碎的边缘边缘形成到面板中,以产生与门周边相当的强度差异,以促进沿着铰链的弯曲和/或有助于在气囊展开期间将撕裂限制在易碎边缘。
