  • the exemplary embodiment according to FIGS. 12 and 13 differs from that according to FIGS. 10 and 11 in that, in the embodiment according to FIGS. 12 and 13, the counterweight surface 13 is not on or above the glass roof 5, 5 a, that is to say generally not electrically conductive material 3 "of the existing motor vehicle body 3, but in a recess 71 provided in the glass roof 5, 5a at the location where the counterweight surface 71 is seated 5 'of the glass or glass roof 5, 5a are in the same level, ie in the same or almost the same plane, thus preferably flush with each other at their junction 115.
