<p>A door beam has a double hat profile between its mounting ends (12, 13). The height of the outer sidewalls (14, 15) of the double hat profile decreases from a central part (25) of the beam towards the mounting ends (12, 13). Thus the height ratio between the outer (14, 15) and the inner (18, 19) sidewalls is decreased towards the mounting ends.</p> |
