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. |

1. Door beam for vehicles with attachment ends (12, 13) to the vehicle and a double hat profile between the attachment ends, comprising two outer side walls (14, 15) with lateral flanges (16, 17), two inner side walls (18, 19), two apexes (20, 21) defined between the outer and inner side wails and directed outwards from the vehicle, and an apex (22) defined between the inner side walls and directed inwards towards the vehicle, wherein the height of the outer side walls (14, 15) decreases from a central part (25) of the beam towards the attachment ends (12, 13) so that the ratio in height between the outer and the inner side wails decreases towards the attachment ends. |
