<p>The framing which is provided with a backrest, is especially for public vehicles. The object is to provide a framing, which can be used for both right and left hand placing, which admits a very quick exchange of backrest and which requires little space during transport and stock-keeping. This has been achieved by the fact that the framing (11) comprises a rectangular frame (12, 13, 14) for receiving at least one seat. In both the essentially parallel long sides (12) of the frame there are arranged double pairs of collar bearings (16) located just opposite each other and provided with rubber grommets (20), said collar bearings being arranged and designed for receiving horizontal supporting beams (18) from the backrest (17). The supporting beams are insertable from an optional long side of the frame and are arranged to extend across the frame and to be received in the respective collar bearing (16) in the opposite long side (12). A locking means (23) is attachable in each collar bearing (16) for axially fixing the supporting beams (19) of the backrest.</p> |
