Rear structure for an electric vehicle having a rear rail which includes a rear portion, a front portion and a transition zone, such that in the event of a rear crash the rear portion and the transition zone are both able to deform to maximize the amount of energy absorption.

Rear structure for an electric vehicle

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.

Front structure for an electric vehicle

A method is for producing a three-dimensional vehicle door frame inner reinforcement element () including an inner center pillar part (), an inner front pillar part () and an inner side rail part () joining the inner center pillar part () and the inner front pillar part (). 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 ().

Methods for producing a three-dimensional vehicle door frame inner reinforcement element, for producing a vehicle door frame and for producing a vehicle reinforcement structure

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 () extending in a plane substantially perpendicular to the main direction. The reinforcing cross-section () includes at least four adjacent branches (), 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.

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.

Vehicle front body structure and method for manufacturing thereof

A bumper-reinforcing system () intended for a motor vehicle includes:

Bumper-reinforcing system for motor vehicle

The vehicle underbody structure () includes a floor panel () and an underbody reinforcement element (), the underbody reinforcement element () including at least a front transversal beam () and a rear transversal beam (), the transversal beams () extending parallel to each other and being attached to the floor panel (). The front transversal beam () and the rear transversal beam () are made of a press hardening steel having a tensile strength higher than or equal to 1300 MPa.
