    • A bumper has a bumper frame and an inflatable bladder, which is mounted to the bumper frame to extend exteriorly of the bumper frame. Fluid flow ports extend from the inflatable bladder, in fluid communication with the interior of the inflatable bladder. Inlet valves and pressure relief valves are mounted in the flow ports for sealing air within the inflatable bladder. Two impact members are mounted to the bumper frame, extending outwardly from the bumper frame and interiorly within the inflatable bladder. The impact members are connected to respective ones of the pressure relief valves, such that inward movement of the impact members will open the pressure relief valves to allow fluid flow from within the inflatable bladder. Latch members are located adjacent to the pressure relief valves for securing the valves in open positions after impact. An activator stem is secured adjacent to an inward end of a stem of one of the pressure relief valves, and is moved inward of the bumper frame by contact with the stem of the pressure relief valve during an impact. A pressure relief valve is also provided which includes a plug member having a plurality of seal grooves for receiving elastomeric seal elements, the number of grooves which are used being selected to determine a maximum pressure for release of the plug member from within a flow port. The plug member is secured to the flow port by a tether member.
    • 保险杠具有保险杠框架和可膨胀的气囊,其被安装到保险杠框架以在保险杠框架的外部延伸。 流体流动端口从可充气囊膨胀,与可膨胀囊的内部流体连通。 入口阀和减压阀安装在流动端口中,用于密封可充气囊内的空气。 两个碰撞构件安装在保险杠框架上,从保险杠框架向外延伸,并在内部可膨胀的气囊内。 撞击构件连接到各个压力释放阀,使得冲击构件的向内运动将打开压力释放阀以允许流体从可充气气囊内流出。 闩锁构件位于靠近压力释放阀处,用于在冲击后将阀门固定在打开位置。 活塞杆靠近一个泄压阀的杆的内端固定,并且在冲击期间通过与减压阀的杆接触而在保险杠框架的内部移动。 还提供了一种压力释放阀,其包括具有用于接收弹性体密封元件的多个密封槽的塞子构件,所选择的凹槽的数量被选择以确定用于从流动端口内释放塞子构件的最大压力。 插塞构件通过系绳构件固定到流动端口。
