    • A self-reinitializing padding device having at least two fluidly connected chambers which contain flowable material for use in applications where it is desirable to reinitialize the padding device for subsequent use in absorbing and/or distributing impact forces. One application for which the padding device is particularly well suited is as a foot padding device in footwear. In this application, the device provides improved absorption and distribution of impact forces generated when the footwear contacts a surface, as well as improved lateral support for the foot. In a preferred embodiment, a primary chamber is positioned under the area to be padded, and a plurality of secondary chambers, each fluidly connected to the primary chamber, are positioned around the padded area. The impact force of the user's foot deforms the primary chamber, thereby forcing some of the flowable material contained therein to flow into the secondary chambers. The rate of deformation of the primary chamber exceeds the flow rate into the secondary chambers, thereby providing a cushioning effect. When the portion of the footwear coinciding with the primary chamber loses contact with the ground, the force is removed from the primary chamber, thereby allowing the secondary chambers to contract and force some of the flowable materials contained therein back into the primary chamber to reinitialize the padding device.
    • 一种具有至少两个流体连通的室的自重新填充装置,其包含可用于需要重新初始化填充装置以用于吸收和/或分配冲击力的应用中的可流动材料。 衬垫装置特别适合的一种应用是鞋类中的脚垫装置。 在该应用中,该装置提供了当鞋类接触表面时产生的冲击力的改进的吸收和分布,以及改进的脚的侧向支撑。 在优选实施例中,主室位于待填充的区域下方,并且每个流体连接到主室的多个次室位于填充区域周围。 使用者的脚的冲击力使主室变形,从而迫使其中容纳的一些可流动材料流入次室。 主室的变形率超过进入二次室的流量,从而提供缓冲效果。 当与主室相重合的鞋类部分与地面相接触时,力从主室移除,从而允许二级室收缩并将其中容纳的一些可流动材料推入主室以重新初始化 填充设备
