Abstract: A B-pillar for a vehicle is made by the press hardening method. The blank is made by placing two blank elements (20,21) with an overlap (23) and welding the elements together before the shaping process.

Abstract: A B-pillar is shaped from a sheet blank (20,21) into a hat profile with a central flange (12), two sides (13,14) and two side flanges (15,16), and it has, over a portion of its length, a reinforcing sheet (21) that make the B-pillar have double sheets. The reinforcing sheet (21) extends out over the side flanges (15,16) over at least ¼ of its length and narrows down at both its ends so that it does not extend out over the side flanges over part of its length.
