Patent number: 11827275Abstract: A support device (1) of an engine support structure (2) of a motor vehicle includes at least a support part (4), comprising an upper face (10) and a lower face (12) defining between them a hollow volume (14), and at least one fixation device (8) intended to attach the support part to a vehicle body. The fixation device (8) comprises a fixation part (16) and a base part (18) extending at least partially inside the hollow volume (14) of the support part (4), at least a portion of the upper face (10) and at least a portion of the lower face (12) being applied against at least a portion of the base part (18) on either side of said base part (18. The fixation part (16) and the base part (18) are formed of at least two distinct parts attached together.Type: GrantFiled: September 12, 2019Date of Patent: November 28, 2023Assignee: ARCELORMITTALInventors: Jean-Louis Colmont, Thierry Derchu, Sébastien Albeaux, Guillaume De Taillac

Publication number: 20230347981Abstract: 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.Type: ApplicationFiled: April 20, 2020Publication date: November 2, 2023Inventors: Jean-Louis COLMONT, Thierry DERCHU, Edith LAHELLEC

Patent number: 11801800Abstract: An energy absorbing device is designed to increase the amount of absorbed energy and control the deformation of the device in case of an impact. The energy absorbing device consists in a hollow longitudinal member extending along a first longitudinal axis and a longitudinal guide extending along a second longitudinal axis, arranged within the longitudinal member and suitable for guiding the deformation of the longitudinal member in case of an impact. The length ratio between the longitudinal guide and the member is comprised between the values of 1/5 and 3/5.Type: GrantFiled: September 11, 2019Date of Patent: October 31, 2023Assignee: ARCELORMITTALInventors: Jean-Louis Colmont, Thierry Derchu, Sébastien Albeaux, Guillaume De Taillac

Patent number: 10618558Abstract: 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.Type: GrantFiled: October 11, 2016Date of Patent: April 14, 2020Assignee: ARCELORMITTALInventors: Cédric Bouton, Edith Lahellec, Jean-Louis Colmont, Thierry Derchu, Maxime Gabrel

Patent number: 8262151Abstract: An elongate mechanical device for vehicles, for absorbing impacts, which includes a profiled or tubular elongate part of polygonal cross section, and an end part mounted at one end of the elongate part, at an angle perpendicular to the axis of the elongate part, and intended for fastening to other elements. In the vicinity of its end, the elongate part includes cutouts, which create adjusted regions or faces, in the vicinity of edges of its cross section, and a rigid fastening is provided between the elongate part and the end part that maintains the adjusted regions in direct contact with the end part, the adjusted regions being dimensioned to withstand compressive loads and a tilting torque during impacts.Type: GrantFiled: April 24, 2008Date of Patent: September 11, 2012Assignee: ArcelorMittal Tubular Products VitryInventors: Wilder De Queiroz, Thierry Derchu, Raymond Deslande
