摘要

The invention relates to a bellows seal for pivot joints, preferably on motor vehicles, with a bellows (3) which surrounds the joint and which is arranged in a sealed manner on the joint housing (1), on the one hand, and on the pivot (2) on the other. In order to provide a bellows seal which does not produce additional turning moments in the joint and the bellows (3) of which is not twisted when the joint housing (1) and the pivot (2) are rotated relative to one another, a packing ring (4) is inserted with intermaterial engagement into at least one opening in the bellows (3), this ring being connected rotatably via a surface structure of labyrinth-like design, to a mating ring (5) which is fixed on the joint housing (1) or on the pivot (2).
