Abstract

A soft mounting for insulating body transmitted waves comprises a soft support spring block made of elastic material. The support spring block is disposed between two beaker-type housing parts which serve to transfer load forces into the support spring block. The housing parts are arranged coaxially with respect to one another and are telescopically positioned within one another. Elastomer spring elements having cavities located therein concentrically surround the support spring block. The cavities serve to show the effect of a collapse of a spring restoration force by kinking.
