A safety bar for an automotive door has an open substantially trapezoidal, cross section that includes a central flange (6) that is embraced by two webs (7) to which two outwardly directed side-flanges (8) are connected, one at each side of the bar. Between a first section (1) and a mounting section (5) at one end of the bar, the bar has an intermediate section (2, 3) in which the vertical flange has generally a decreasing width and the webs have generally decreasing height. The central flange (6) extends through the mounting section which improves the energy absorbing capacity.
