Patents by Inventor Edith LAHELLEC

Edith LAHELLEC has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12325466
    Abstract: A structural components node (9) a crash box connector (14) and a crash extender connector (13) each having a top plate extending in a substantially horizontal plane and allowing to secure directly together the crash extender (7) and the crash box (8). Advantageously, the structural components node (9) can further optionally include connections with a hanger (10) and a front transverse member (11). It is possible to reduce the amount of welding operations needed to assemble the structural components node (9) and to provide a robust structural components node (9) ensuring a high structural strength to the assembly and an efficient cooperation between the lower and middle load paths and between the left and right side of the vehicle in case of a front impact. A process of assembling such a structural components node (9) is also provided.

  • Patent number: 10618558
    Abstract: A structural component connected to a structural element is provided. The structural component includes an extension extending in a longitudinal direction between a front end and a rear end, the rear end facing the structural element. The structural component also includes a stop element protruding from a longitudinal wall of the extension. The stop element has a contact surface facing a region of the structural element. When the extension is subject to an impact creating forces in the longitudinal direction, the contact surface comes into contact with the region and transmits a part of the forces created by the impact to the region.
