<p>The support (1) has two bearing surfaces that are parallel with respect to each other, and separated from each other by a lateral surface defining a perimeter. The lateral surface comprises through-openings (2) distributed along a line (4) parallel to the bearing surfaces. A stiffening flange (3) is in contact with the lateral surface all along the perimeter of the lateral surface, on or in vicinity of the line of the through openings. The through-openings are regularly spaced and shifted by a half period relative to an adjacent line of the through openings.</p> |
