Abstract
A stack of sheet elastomers, each having multiple holes therein, dissipates shock forces applied to it. The elastomeric sheets are formed with identical holes each of which have a periphery that is symmetrical around the centers of the holes that extend over a shock dissipation area of the device. The sheets are stacked so that one, or more continuous material passageways are formed through the stack that extend from one support surface to a parallel support surface. This allows for the elastomer material of these passageways to transmit sheer shock forces when a compressive force is applied normal to the support surfaces. Elastomeric, or other material of a composition different, preferably elastomeric, from the material of the stacked sheets, may be filled into holes of the sheets to adjust the characteristics of the device.
