The device has a cross strut of an extrusion-molded profile, with outer and inner vertical walls (5,6) and two connecting horizontal walls (7,8). At least one horizontal wall is bowed towards the other horizontal wall by a set dimension (A1,2). The distance (DI) between the horizontal walls is smaller on the inner vertical wall than the distance (DA) on the outer vertical wall. The horizontal walls consist of inner sections (10) connected to the inner vertical wall, and outer sections (12) connected to the outer vertical wall.
