<p>The cover, a shallow, inverted U-shape, with turned-down side edges (18, 19) includes a slot (20) in its central bridging section (17), which runs between the edges (18, 19). The slot continues, cutting through one edge (18). On the other side (19) it transitions into a bending edge (23). This allows the two parts (25, 26) of the bridging section (17) to be swung about the bending edge . The bridging section is divided by two slots framing a cover section (21). The bridging sections (26, 27) of the cover section (21) can be swung about the bending edge. The intermediate section (24) covers the slot and is attached near it, at one or more fastening locations (22). The cover section carries the fastening locations. The intermediate section is located on the underside of the central bridging section. The intermediate section extends over the entire length of the slot and is curved at the side facing away from the bending edge. The fastening is a riveted- or resistance-welded connection. The bending edge is configured as a hinge. Spacing between two adjacent slots near the bending edges, is narrower than at the opposite side.</p> |
