A flat seal of a metal support with elastomer coating has areas which are usually stressed particularly intensively by local excess pressures and relative movements. Function elements are provided in these areas which relieve the stress of the seal. The function elements can be foils of metal or plastic which are glued on one side or on both sides. Alternatively, a flat metal or plastic element can be inserted into a free-stamped recess of the metal support of the seal and clamped in or glued on there. In both cases, by hardness, structuring and/or thickness of the function element, it is brought about that the forces occurring on the seal do not exceed the permissible material limits. Thereby, an excessive wear of the flat seal is prevented in applications having a high stress.
