Abstract: The reinforcement member includes a body made of a press hardened steel having a tensile strength greater or equal to 1200 MPa. The body is coated with a zinc-based coating or with an aluminum-based coating and extends along a main direction. The reinforcement member also includes at least one tab extending from the body along a transversal direction forming a non-zero angle with the main direction. The bend between the body and the tab defines an intrados and an extrados. The tab is made of a cold bent part of the body, and the elongation of the extrados is between 10% and 25%.

Abstract: A method is for producing a three-dimensional vehicle door frame inner reinforcement element (52) including 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 includes 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, and hot stamping the door frame inner reinforcement blank to shape the three-dimensional door frame inner reinforcement element (52).

Abstract: A design and a production method of a front floor reinforcement structure 1 for a vehicle 3 having a battery pack 5 in the tunnel 7 designed to improve the energy absorption of the vehicle during a side impact by involving the front floor panel 11 in the energy absorption during the side impact. The front floor reinforcement structure 1 includes a front floor cross member 13 having a non-deformable portion 14 located on the end of the front floor cross member 13 closest to the side sill 9 and a deformable portion 16 located on the end of the front floor cross member 13 closest to the tunnel 7. The resistance to plastic deformation of the non-deformable portion 14 is greater than the resistance to plastic deformation of the deformable portion 16, which is itself greater than the resistance to plastic deformation of the front floor panel 11.
