An elastic fluid filled impact absorber, that incorporates permeable barriers, to provide viscous damping. It can also include internal elastomeric solid or foam layers and an improved packaging design. In the figure, the elastic fluid (1), comprising a mixture of many small elastomeric capsules and a matrix liquid is enclosed in a package (2). The magnified view, which is shown on the right of the diagram depicts the structure of the package wall in more detail. Item (3) is part of the inner layer of the package wall and is a woven fabric which becomes permeable when a sufficiently high pressure difference exists across the layer. Item (4) is part of an elastic, impermeable outer membrane layer, which is strongly bonded to the inner layer at intervals in the manner of quilting. During violent impacts, liquid is driven through (3) and forms local liquid filled bubbles such as (5). |
