The arrangement has a transversal support e.g. arch shaped plate transversal support, fixed on a seat structure (8) by a fixation of directional guide median rail (2) and presenting under the form of branches e.g. plate cross-pieces (15, 16). The cross piece has terminal ends supporting I-shaped linear profiles (33, 34) of lateral electrical supply by electrical insulators (27, 28,) and a mechanical direction and distance adjusting unit e.g. tapered shim set. |
