<p>The element has a bar made of thermoplastic resin and a rib (9) made of aluminum, which are pivotably connected with each other in a hinge (7). An outer hook (5) of the rib is aligned to form another hinge with an outer hook (6) of the bar. The rib has two inner hooks of opposite curvature, where one inner hook is engaged in an inner hook of the bar. Another inner hook of the rib extends around an outer side of the inner hook of the bar. The inner hooks of the rib have a surface concentric to a pivot axis of the former hinge. The pivot axis runs along a corner of the bar and/or the rib.</p> |
