    • An active bolster has a plastic-molded, expandable front wall and a plastic-molded back wall joined around a substantially sealed perimeter with the front wall to form an inflatable bladder. The back wall includes at least one active vent and at least one substantially circumferential pleated baffle. An inflator couples an inflation gas into the inflatable bladder in response to a crash event of the vehicle. The active vent comprises a window opening in the back wall and an integrally-molded flap juxtaposed to the window opening. The flap has an undeflected position corresponding to a first flow coefficient and a deflected position corresponding to a second, nonzero flow coefficient that is less than the first flow coefficient. The flap moves from the undeflected position to the deflected position when a pressure in the inflatable bladder resulting from a passenger impact is greater than a predetermined pressure.
    • 主动枕头具有塑料模制的可膨胀的前壁和与前壁围绕基本密封的周边连接的塑性模制后壁,以形成可充气的囊。 后壁包括至少一个活动通气口和至少一个基本上圆周的褶皱挡板。 充气机响应于车辆的碰撞事件将充气气体耦合到可膨胀的气囊中。 活动通风口包括在后壁中的窗口开口和与窗口开口并置的整体成型的翼片。 翼片具有对应于第一流动系数的偏转位置和对应于小于第一流动系数的第二非零流动系数的偏转位置。 当乘客冲击导致的可膨胀气囊中的压力大于预定压力时,挡板从未偏转位置移动到偏转位置。
