1. A device for stabilizing movements of two parts, movable relative to one another, of a body region and/or a sports device, comprising:
a receptacle adapted to be fixed on a first part of a body region or a sports device, or both, the receptacle being filled with a filling medium,
at least one active body arrangement with an active body which is received displaceably in the receptacle and can interact with the filling medium,
a force transmission body which can be fixed on a second part of the same body region and/or the same sports device for transmitting an external force to the active body,
the active body comprising at least one passage opening, through which the filling medium can flow,
the active body arrangement comprising a sealing lip for sealing a gap between an inner side of the receptacle and a lateral region of an outer side of the active body arrangement, the sealing lip being arranged on an outer side of the active body, and
the active body arrangement having a region of the sealing lip, which region bears against the inner side of the receptacle and extends at an angle with respect to a lateral region of the outer side of the active body, the angle being variable, the active body arrangement is configured to compensate for size fluctuations of the gap between the inner side of the receptacle and the lateral region of the outer side of the active body arrangement and configured to seal the gap even in the case of size fluctuations of this type.
