    REINFORCEMENT OF THE FRONT STRUCTURE OF A MOTOR VEHICLE FOR FRONTAL SHOCK WITH LOW OVERLAP.
    FR 3 058 110 - A1 tiV) Motor vehicle (1) comprising, at least on one side laterally to a longitudinal axis of said vehicle: a front wheel, a generally vertical profile, called the front foot (5), located at the rear of the front wheel; a transverse wall, called a wheel arch (7), adjacent to the front leg (5), and delimiting the passenger compartment of the vehicle (1); a reinforcement (9) fixed to the front foot (5) and to the wheel arch (7), and configured to interfere with the front wheel and limit an intrusion of said wheel into the passenger compartment in the event of a frontal collision on the part of the vehicle (1) located at the front wheel; characterized in that the or each of the reinforcements (9) comprises a generally flat central portion (9A) extending transversely along the front leg (5) and the wheel arch (7).
    REINFORCEMENT OF THE FRONT STRUCTURE OF A MOTOR VEHICLE FOR
    LOW OVERLAP FRONTAL SHOCK
    The invention relates to the field of motor vehicles, more particularly to the reinforcement of vehicles to counter a frontal impact.
    In a crash, the bumper plays an important role in protecting the driver and front passenger. New low impact front impact protocols are currently being implemented and relate to collisions on 25% of the front and side of the vehicle. This type of shock does not allow efficient operation of the entire bumper. In fact, these shocks cause the front wheel to rotate and pivot towards the passenger compartment, causing damage to the front apron and, consequently, to the person positioned at this level in the vehicle. This is why the installation of complementary structures, making it possible to avoid or limit the rotation of the front wheel, is useful for improving passenger safety.
    The patent document published US 2014/0091593 A1 discloses a gusset positioned inside the passenger compartment, behind the front foot and the front wheel arch, the purpose of which is to strengthen the connection between the front foot and the tire tracks. This gusset is made in one piece and is securely attached to the underlying structure, allowing the deck to maintain its integrity. Even if it limits the sinking of the wheel towards the interior of the passenger compartment, it does not prevent its pivoting.
    The patent document published FR 3 002 200 A1 discloses a sliding surface positioned anterior to the front foot and consolidated at the rear by a filling element. This filling element improves the sliding of the wheel outwards in the event of a frontal impact. However, the integration of these structures into the vehicle requires modification of the vehicle, making its manufacture more complex. In addition, it does not absorb the impact of the wheel against the wheel arch.
    Patent document published US 2015/0246692 A1 discloses a reinforcement for the front foot of a motor vehicle. It consists of a sheet metal part fixed to the front leg and to the front wheel arch. This reinforcement forms an edge in the middle which is directed towards the wheel in order to engage with the rim and to separate it following a frontal impact. This structure does not prevent a rotation of the wheel inward, which is actually necessary for it to be torn and that it can participate in the absorption of shock.
    The aim of the invention is to overcome at least one of the drawbacks of the above-mentioned state of the art. More particularly, the invention aims to prevent the front wheel from violating the integrity of the passenger compartment in the event of a front impact with low overlap.
    The invention relates to a motor vehicle comprising, on at least one side laterally to a longitudinal axis of said vehicle: a front wheel; a generally vertical profile, called the front leg, located at the rear of the front wheel; a transverse wall, called a wheel arch, adjacent to the front foot and delimiting the passenger compartment of the vehicle; a reinforcement fixed to the front foot and the wheel arch, and configured to interfere with the front wheel and limit an intrusion of said wheel into the passenger compartment in the event of a frontal collision on the part of the vehicle located at the front wheel; remarkable in that the or each of the reinforcements comprises a generally flat central portion extending transversely along the front foot and the wheel arch.
    According to an advantageous embodiment of the invention, the central portion of the or each of the reinforcements comprises an inner lateral end with a flange intended to engage with the front wheel during the frontal collision.
    Advantageously, the rim forms a generally vertical edge.
    This edge extends forward of the reinforcement.
    According to an advantageous embodiment of the invention, the central portion of the reinforcement or reinforcements comprises an exterior face that is generally flat and at a distance from the front leg and the wheel arch.
    Advantageously, the or each of the reinforcements comprises ribs generally extending longitudinally between, on the one hand, the external face and, on the other hand, the front foot and the undertray, said ribs bearing on said front foot and said wheel arch.
    The central portion can then have a thickness between 1 and 3mm, and, in a preferred embodiment, a thickness of 2mm. The network of ribs can have a diamond structure. The fixing of this reinforcement on the front passage of the wheel and on the front foot can be achieved by several known techniques, in particular by gluing.
    According to an advantageous embodiment of the invention, the ribs form a notch conforming to a vertical rebate for joining sheets to the front of the corresponding front leg.
    The reinforcement can be constructed from different materials, in particular from composite plastic, for example from BMC material (acronym for “Bulk Molding Compound”) or from SMC material (acronym for “Sheet Molding Compound”); but also in fiberglass. This type of reinforcement has a damping function which is achieved by compressing the composite box.
    Advantageously, the or each of the reinforcements comprises two lateral portions, on either side of the central portion, said lateral portions extending mainly longitudinally and bearing on the front foot and the wheel arch, respectively.
    According to an advantageous embodiment of the invention, the two lateral portions of the or each of the reinforcements are fixed to the front leg and to the wheel arch, respectively.
    This fixing can be carried out by welding. It can optionally be done by bonding the reinforcement to the front foot and to the front wheel arch of the vehicle.
    Advantageously, the or each of the reinforcements comprises a sheet metal element, preferably in one piece.
    According to an advantageous embodiment of the invention, the or each of the reinforcements comprises a pin projecting from the central portion towards the rear of the vehicle, said pin engaging in a corresponding orifice of a sheet metal element fixed to the front foot and at the wheel arch.
    The sheet metal element is advantageously fixed to the structure by known fixing methods, for example by welding. The reinforcement can be made of plastic. This configuration allows to have a damping function which is done thanks to the compression of the plastic.
    The measures of the invention are advantageous in that they allow a reinforcement of the front structure of a motor vehicle, thanks to an added part that is both light and easy to manufacture. This reinforcement can be easily integrated into vehicles intended for certain markets, such as the USA and China, presenting particular requirements for frontal impacts with low overlap, and this without modifying the design of the vehicle. This reinforcement provides better protection for vehicle passengers, as it helps cushion the impact of the wheel on the front wheel arch, and prevents it from rotating towards the passenger compartment.
    Other characteristics and advantages of the present invention will be better understood from the description and the drawings, among which:
    - Figure 1 is a partial view from below of the front of a motor vehicle showing the reinforcement according to the invention;
    - Figure 2 is a perspective view of a reinforcement between the wheel arch and the front leg of a motor vehicle according to a first embodiment of the invention;

    Figure 1 is a bottom view of a motor vehicle 1. In the front and side of the vehicle is a front wheel 3, at the rear of which is placed a profile structure corresponding to the lower portion of a front foot 5. At the rear of the wheel and at the front of the foot is positioned a slightly curved element towards the interior of the vehicle which corresponds to the wheel arch 7. It is at this wheel arch that finds a reinforcement 9 according to the invention.
    Figures 2 and 3 show the reinforcement 9 according to a first embodiment of the invention. This reinforcement comprises several portions: a lateral portion 9B fixed to the wheel arch 7, a central portion 9A extending transversely between the foot 5 and the front wheel arch 7, and a lateral portion 9C fixed to the front leg 5. The central portion 9A is generally flat. It can have a length between 70 and 150mm, more preferably between 90 and 130mm. The central portion of the reinforcement 9A has, in its inner lateral end positioned towards the wheel arch 7 of the vehicle, a flange 9D. This 9D rim has the particularity of having an edge-shaped structure which points towards the rear of the vehicle. The central portion 9A may have a longitudinal stiffening 11, preferably positioned in the middle and over the entire length of the outer face 9E. Finally, this reinforcement 9 may have fallen edges 9F, which are positioned at the ends of the lateral portions 9B and 9C of said reinforcement. These fallen edges 9F form tabs which will allow the fixing of the reinforcement 9 both on the foot 5 and on the front wheel arch 7 of the vehicle 1. The fixing of this reinforcement can be done by known methods, such as for example by welding. The reinforcement is, in this embodiment, preferably made of stamped sheet metal and more particularly of DP450 steel.
    Figures 4 to 7 show a reinforcement 109 according to a second embodiment of the invention. These figures show the numbering of the previous figures for identical or similar elements, the number being however incremented by 100. Reference is also made to the description of these elements in relation to the first embodiment. Specific numbers between 100 and 200 are used for the elements specific to this embodiment. This reinforcement 109 has a central portion 109A, two lateral portions 109 B and C, as well as a flange 109D and the dropped edges 109F as described above. This reinforcement also has the particularity of presenting a pin 113, which will be more fully described in relation to FIGS. 6 and 7, and which is directed towards the rear of the reinforcement 9 to be embedded in a sheet metal element 115.
    FIG. 5 shows more precisely this element made of sheet metal 115. It has a structure similar to the reinforcement 9 of FIGS. 2 and 3, with a central portion 115A, and two lateral portions 115B and C, respectively for fixing the element 115 at the wheel arch 107 and at the front foot 105 of the vehicle 101. This metallic element also has an orifice 117, which will make it possible to accommodate the pin 113 of the reinforcement 109. This orifice is preferably ovoid in shape, but must correspond to the shape of the pin 113 to allow a good arrangement between these two elements.
    The reinforcement 109 is positioned at the front of the structure. It is advantageously made of plastic (BMC: “Bulk Molding Compound”), or of dense polypropylene foam. It has a wall thickness preferably between 2 and 3mm, and, according to a preferred embodiment of the invention, its wall has a thickness of 2.5mm. On the inner face of the central portion of the reinforcement 109 is the pin 113, preferably ovoid in shape and corresponding to the shape of the orifice 117 of the sheet metal element 115 described in FIG. 6. This reinforcement 109 and the pin 113 are preferably made in one piece.
    Figures 8 to 10 show a reinforcement 209 according to a third embodiment of the invention. These figures show the numbering of Figures 2 and 3 for identical or similar elements, the number being however incremented by 200. Reference is also made to the description of these elements in relation to the first embodiment. Specific numbers between 200 and 300 are used for the elements specific to this embodiment. This reinforcement 209 has all the characteristics of the reinforcement 9 described in the first embodiment.
