Abstract: The reinforcement element for reinforcing the structure of a door of a vehicle extends along a main direction and comprises at least a main portion having a reinforcing cross-section (40) extending in a plane substantially perpendicular to the main direction. The reinforcing cross-section (40) includes at least four adjacent branches (42a, 42b, 42c, 42d, 42e, 42f, 42g ), each extending in different directions, two successive branches forming a non-zero angle, at least two of the non-zero angles being of opposite signs.

Abstract: Methods for producing a three-dimensional vehicle door frame inner reinforcement element, for producing a vehicle so door frame and for producing a vehicle reinforcement structure A method for producing a three-dimensional vehicle door frame inner reinforcement element (52) comprising an inner center pillar part (66), an inner front pillar part (68) and an inner side rail part (64) joining the inner center pillar part (66) and the inner front pillar part (68). The method comprises: providing an inner center pillar blank, an inner front pillar blank and an inner side rail blank, said inner blanks being substantially planar, assembling the inner center pillar blank and the inner front pillar blank to the inner side rail blank in order to form a substantially planar door frame inner reinforcement blank, hot stamping the door frame inner reinforcement blank to shape the three- dimensional door frame inner reinforcement element (52).
