Abstract
A convoluted boot for sealing an annular gap between two parts which are connected to one another in a rotationally fast way, which can be articulated relative to one another and which are axially displaceable relative to one another, especially of a constant velocity plunging joint, consisting of includes a low-strain polymer hard material having a first larger collar () to be secured to a first component, a second smaller collar () to be secured to a second component and a plurality of annular fold units which extend between the first collar and the second collar and which, in the form of the outer folds consisting of have two annular flanks (), and form a fold peak () between two fold valleys (). In a first group (A) of at least three annular folds with a connection to the first collarannular folds, the diameters of the fold peaks () and fold valleys () decrease in the direction from the first collar to the second collar. In a second group (B) of annular folds with a connection to the second collarof at least one fold, the diameters of the fold valleys and, optionally, of the fold peaks () are constant. The ratio of the diameter (D) of the fold peak () of the largest annular fold (A) of the first group (A) to the diameter (D) of the second collar () is greater than or equal to 2.5.
