  • support posts 3, 4 of the first pair of support posts and the support posts 6, 7 of the second pair of support posts are fixed relative to each other, and fixed relative to the body of the cowling 2, that is to say that they do not move, in particular they are not movable in translation or in pivoting.
  • the support posts 3, 4 of the first pair of support posts and the support posts 6, 7 of the second pair of support posts form between them an angle ( ⁇ ) of between 20° and 90°, for example of the order of 50°.
