Abstract
A convoluted boot made of a resilient material has a first collar with a large diameter and a second collar with a smaller diameter. The collars are positioned on rotatable parts which are rotatable relative to one another in an articulatable and/or axially movable condition. Also, the boot has a guiding portion positioned between at least one first freely deformable and movable fold and at least one second freely deformable and movable fold. The guiding portion is angularly movably held on a guiding member connected to one of the rotatable parts. The guiding member, on its outside, is enveloped and defines a spherical face.

A boot device for rotatable parts which are rotatable relative to one another in an articulatable and/or axially movable direction, comprising:
- a one piece convoluted boot made of a resilient elastomeric material with a first collar with a large diameter and a second collar with a smaller diameter, said collars positioned on said rotatable parts such that said collars are axially fixably positioned on the rotatable parts;
- a guiding portion positioned between said collars;
- at least one first freely deformable and movable fold between said large diameter collar and said guiding portion;
- at least one second freely deformable and movable fold between said smaller diameter collar and said guiding portion;
- said guiding portion is adapted to be angularly movably held on a guiding member slidably connected to one of the rotatable parts, the guiding member having a face portion on its outside, being enveloped and defined by a geometrical sphere.

- a guiding portion positioned between said collars;
- at least two first freely deformable and movable folds between said large diameter collar and said guiding portion;
- at least two second freely deformable and movable folds between said smaller diameter collar and said guiding portion;
- said guiding portion is angularly movably held on a guiding member which is axially rigidly arranged on one of the rotatable parts, the guiding member having a face portion on its outside, being enveloped and defined by a geometrical sphere.
