ABSTRACT:
The invention relates to a sealing collar for a cylinder-and-piston unit, wherein the sealing collar is essentially received in a groove that is inserted into the cylinder or the piston, respectively, and the sealing collar comprises two sealing lips, the first sealing lip thereof being acted upon dynamically and making catch at the piston or the cylinder, respectively, while the second sealing lip thereof is acted upon statically and rests on a bottom of the groove.It is the core of the invention that the sealing collar includes a circumferential extension that extends in parallel to the sealing lips, is arranged radially between the first sealing lip and the second sealing lip and projects from the sealing lips in an axial direction.
