An anchorage system to hold a rail (7, 7', 13, 18) to ribbed sheet metal floors (1) such as those in vehicles has a bridge (4; 4'; 14, 15; 19) securable across adjacent ribs (2). The bridge (4, 4') may be separate from the rail (7, 7') (which runs parallel to the ribs) and their mutual engagement may be by an undercut tongue (6, 10) and a complementary groove (8, 9), such as an elongated dovetail joint. Alternatively, rail (13, 18) and bridge (14, 15; 19) may be a single extrusion, the bridge being hollow but spanned by one or more strengthening webs (16, 28). |
