The carrying arm (16) is elastically deformable, and by means of the guide (20) is guided out from a rest position in to an operating position by swiveling. The carrying arm (16) is preloaded by means of the guide (20) in its rest position. The carrying arm (24,fig.6) is curved and by means of the guide (25,fig.6), is movable from a stretched rest position in an essentially tension free operating position.
