Abstract: The invention relates to a convoluted boot which serves to seal an annular gap between an outer joint part of a tripode joint and a shaft connected to the inner joint part of the tripode joint. The convoluted boot 1 comprises an elastic adapter ring 2 for being attached to the outer joint part and a boot portion 3 connected thereto and extending between the adapter ring 2 and a collar 5 for being fixed to the shaft. The adapter ring 2 comprises a cylindrical outer face 10 and an inner face 8 whose cross-section is adapted to the outer contour of the outer joint part and which is form-fittingly positioned on the outer joint part. At least in partial regions of the wall formed between the inner face 8 and the outer face 10, there is provided a plurality of holes 12 which start from an end face or radial face of the adapter ring and are arranged to form a honeycomb-like structure.

Abstract: An expanding bellows is disclosed for sealing an annular gap between two parts, which are connected to one another in a rotationally fixed manner and may be angled to one another, in a constant velocity joint. The expanding bellows has a first larger flange and a second smaller flange and an annular fold area, which extends between the first flange and the second flange, having annular folds implemented as outer folds, each having two annular flanks and a fold peak between two fold valleys. The expanding bellows further comprises a first area of at least two annular folds adjoining the first flange having diameters of the fold peaks and fold valleys decreasing in the direction toward the second flange and a second area having at least one annular fold adjoining the second flange having essentially uniform diameters of the fold valleys. As use of the expanding bellows is also disclosed.
