Abstract

A piston ring for the piston of a vibration damper includes a jacket and supporting segments connected to the jacket with holding surfaces. The supporting segments are supported axially on an upper side and a lower side of the piston by the holding surfaces. The piston ring has a seal carrier in which at least one seal is embedded, wherein the seal is oriented toward the piston proceeding from the seal carrier.
