Abstract

The aperture between a positionally stable vehicle passenger space end wall and a steering spindle shaft penetrating a bore in the wall is masked by a sealing sleeve which exhibits a bellows which compensates an offset of the shaft by modification of its form. Attached to the sealing sleeve is a second sleeve with which the first sleeve forms a sound-insulating closed air chamber.
