<p>The rail has a stabilizing unit (SR) connected with an elongated profile body (PK2) e.g. aluminum extruded section, where the stabilizing unit stiffens the profile body against deflection and elongatedly runs in its longitudinal direction. The profile body has a chamber (K2), which is closed in a cross section, and the stabilizing unit lies at a part of chamber walls. The stabilizing unit is made of steel and plastic. The rail is bulged in an arc-shaped in an unloaded condition. An independent claim is also included for a method for manufacturing a roof rail.</p> |
