Definitions

• the present invention claims priority from French application 2213900 filed on December 20, 2022, the content of which (text, drawings and claims) is here incorporated by reference.
• the invention relates to a reinforcement bracket for a vehicle tunnel.
• the invention therefore aims to propose at least one solution which overcomes this drawback.
• the invention relates to a reinforcement bracket for a vehicle tunnel.
• said stirrup comprises at least two reinforcing elements and at least one connecting element of the at least two reinforcing elements, each reinforcing element comprising a main face having substantially a U shape and at least two lateral sides, the main face comprising a transverse part and two branches, the at least two lateral sides projecting from each branch, the at least one connecting element comprising a flat face and at least two lateral sides projecting from either side of said flat face, the at least one connecting element being configured to be positioned between the at least two reinforcing elements, the at least two sides of the connecting element bearing on the two main faces of the at least two elements reinforcement at the level of the transverse parts, the connecting element making it possible to maintain the at least two reinforcing elements substantially opposite each other.
• the invention makes it possible to preserve the structural integrity of the base in the event of a side impact of a vehicle with a post at an angle of 75° at 32 km/h, for example without an aluminum profile.
• the invention therefore aims to reinforce the tunnel by adding a stirrup according to the invention.
• the invention consists of reinforcing the interior of the tunnel in the part in connection with a front seat crosspiece and distributing the forces between heel board, seat crosspiece and leg A.
• a stirrup according to invention is added in the area while respecting a functional clearance of 25 mm between the silencer and the tunnel.
• This solution makes it possible to correct the opening problem between the tunnel and the floor, and also corrects the problem of unbuttoning of the welding points in this area.
• the invention provides better structural behavior of the base.
• the invention also allows a significant gain with regard to the manufacturing cost price and the mass given the elimination of the aluminum profile in the spar.
• the stirrup according to the invention is positioned between the front seat crossmembers and contributes to resistance to deformation in the event of a side impact. [0006]
• Each reinforcing element can have a height of 134 mm.
• Each reinforcing element can have a length of 164 mm.
• Each reinforcing element can have a thickness of 2 mm.
• Each reinforcing element can be made of DP980.
• Each connecting element can be made of DP 1180.
• the invention also relates to a vehicle tunnel comprising at least one stirrup according to the invention.
• the invention also relates to a motor vehicle comprising at least one tunnel according to the invention.
