The invention provides a reverse-weakened passenger air bag door. An instrument panel for a passenger compartment of an automotive vehicle comprises a molded plastic substrate and a skin covering thesubstrate. The substrate has inner and outer surfaces, and is adapted to be mounted in the passenger compartment adjacent a windshield. The inner surface is adapted to receive an air bag chute assembly for deploying an air bag. The inner surface is inscribed by a door groove defining a deployment door at least partially tearing open to expel the air bag. The outer surface is inscribed by a hinge groove following a chord path bisecting the outer surface of the deployment door and configured to bend in response to an edge of the deployment door impacting the windshield. The impact force againstthe windshield is reduced while stiffness of the door against the air bag remains high to facilitate tearing open of the door by the air bag.

    本公开提供了“背面弱化的乘客安全气囊门”。一种用于机动车辆的乘客舱的仪表板,包括模制塑料基板和覆盖所述基板的蒙皮。所述基板具有内表面和外表面,并且适于邻近挡风玻璃安装在所述乘客舱中。所述内表面适于接收用于展开安全气囊的安全气囊滑槽总成。所述内表面刻出门凹槽,所述门凹槽限定展开门,所述展开门至少部分地撕开以排出所述安全气囊。所述外表面刻出铰链凹槽,所述铰链凹槽沿循将所述展开门的所述外表面二等分的弦路径并且被配置为响应于所述展开门的边缘碰撞所述挡风玻璃而弯曲。减小了对所述挡风玻璃的碰撞力,同时所述门对所述安全气囊的刚度保持较高,以便由所述安全气囊撕开所述门。
