  • Publication number: 20090066125
    Abstract: An energy absorption device including an elastic core. The elastic core includes an elastic material, a covering enclosing the elastic core, and at least one flow device. Air contained in the elastic core may escape through the flow device into the space outside the covering when the elastic core is compressed. Additionally, air flows through the flow device into the space enclosed by the covering when the elastic core expands. The covering is constructed of a flexible, expansion-resistant material. The flow device is designed in the form of at least one connecting point between the covering elements of the covering such that air can escape from the elastic core or can flow into the elastic core through the connecting point.
