| Abstract: |
The present invention relates to a light weight energy absorbing and damping device having a predetermined configuration, which is a composite of a foam element, and at least one visco-elastic element, each said visco-elastic element being permanently affixed by chemical bonding in a portion of the device through which energy is normally transmitted. The device may be configured to all or part of a shoe part or insole, a glove, a seat or seat pad, a helmet or helmet liner, a dash-board liner, head support pad or other energy absorbing or protection devices.
