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: Front structure for an electric vehicle including a lower dash panel, a seat cross-member and a tunnel nose, such that the tunnel nose is designed to absorb energy in its front portion while resisting intrusion in its rear portion, optimizing the energy absorption in the part during a front crash and protecting the battery pack from being breached by the downward pushing effect of the lower dash panel.

Abstract: A vehicle front body structure containing an upper longitudinal beam and a upper fender rail for supporting a fender of the vehicle, said upper fender rail extending in a longitudinal direction substantially parallel to the upper longitudinal beam and having a front end and a rear end spaced apart along the longitudinal direction.The resistance to plastic deformation of the upper fender rail increases from the front end of the upper fender rail to the rear end of the upper fender rail. The yield strength of the material of the rear section is greater than the yield strength of the material of the front section and/or the rear section has a greater wall thickness than the wall thickness of the front section.
