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.
Claims19
A light weight energy absorbing and damping device having a predetermined configuration and an overall density of less than 1 which is a composite of a polyurethane foam element, and at least one polyurethane viscoelastic element, each said visco-elastic element being permanently bonded to said foam by the formation of urethane bonds at the interface between said foam element and each said visco-elastic element in a portion of the device through which energy is normally transmitted.
