Definitions

• the present invention relates to a hinge for an opening of a motor vehicle comprising a body structure on which are assembled body members, such as an opening, said body structure being obtained from a base and at least one side cockpit assembly together, the opening being mounted hinged to the body structure by means of said at least one hinge.
• articulation hinges having a fixed portion defining an axis of rotation about which a movable knuckle is pivotable to move an opening such as a closing cap of a motor compartment between a position of opening and a closed position.
• the articulation hinges of a closing cap of a motor compartment are often made from a material with little resistance to deformation which allows easy formatting and has the advantage of be less expensive.
• hinges do not ensure sufficient maintenance of the cover they connect to the body structure of the vehicle, during a shock of the vehicle with an obstacle, which causes demerit of the vehicle compared to certain standards regulations.
• the hinges do not oppose the lateral movement of the hood during a shock, which increases the risk of deformation of the surrounding body parts, such as a front side wing.
• lateral displacement the hood (along the transverse axis Y of the vehicle) also causes the deformation of the wing and therefore causes an additional cost of repair related to the replacement or repair of the wing.
• one possibility is to stiffen the movable part or moving hinge of the hinge.
• stiffening leads to a degradation of the head-to-pedestrian shock performance in that the deformation stroke of the moving knuckle between the hood and the engine elements is then very limited.
• a device for retaining an opening comprising a body structure on which are assembled body members, such as an opening, said body structure being obtained from a base and at least one side of the cabin assembled together, the opening being articulated on the body structure by means of at least one hinge and which comprises at least one piece forming a stop intended to oppose the lateral displacement of at least one of the body members during a shock, each piece forming a stop being made of a material of greater resistance to deformation than the material used for the manufacture of said body structure.

• the lug protruding from said movable portion of the hinge and extending in the pivot plane of the hinge is preferably , arranged rather close to the free end of the movable part, that is to say away from the connection moving part / fixed part.
• This tab is further arranged to extend facing a structural element of the body when the hinge is in the closed position and, in case of impact of the type repairability, this tab can abut against this structural element of the vehicle so as to avoid spillage of the Y-closing hood.
• the movable portion of the hinge has a shape called gooseneck, that is to say having two curved portions with inverse curvature.
• the first curve of the movable portion corresponds to a hooking portion pivotally mounted about an axis of the fixed portion of the hinge and the second curve corresponds to the end of the movable part on which the cover will be fixed, the tab extending radially projecting inside the second curve of the side opposite the hood, in the plane of pivoting of said movable portion relative to the fixed part.
• the invention also relates to a hinge assembly of an opening on a motor vehicle body, comprising a hinge according to the invention and a support for fixing the hinge, characterized in that the fixing support comprises a plate fixing means for fixing the fixed part of the hinge and has a wall extending perpendicularly to said fixing plate, the movable part of the hinge provided with the tab being arranged to extend along the perpendicular part of the support of fixing in the closed position of the hinge.
• the mounting bracket allows to fix the hinge on structural elements of the body and is a structural element.
• the mounting plate of the support makes it possible to fix the Z-shaped hinge (vertical axis of the vehicle) on the body of the vehicle while the wall perpendicular to the fixing plate of said support allows, by its external face, a Y-attachment on a structural element of the body.
• the projecting tab of the movable knuckle extends along the inner face of the wall of the fixing support, thus interposed between the tab and a structural element on which the support is fixed and, in the event of a frontal impact against a wall, the hood or opening which tends to be driven in translation in the Y direction of the vehicle is prevented by the tab which bears against the wall of the vehicle.
• support for fixing the hinge itself fixed on a structural element of the body.
• the tab can be integrated directly to the moving knuckle to reduce the number of parts but also to facilitate the assembly of the cover.
• a hinge according to the invention can be advantageously used only on the opposite side to the shock.
• the mass addition is therefore very small.
• the invention also relates to a motor vehicle comprising an opening such as a closing cap of the engine compartment hinged to the vehicle body by means of hinge sash hinges of which at least one is a hinge hinge according to the invention and a motor vehicle comprising an opening such as a closing cap of the engine compartment hinged to the vehicle body using at least one hinge assembly according to the invention.

• a zone D defined by the mixed line locates a possible implantation area on a vehicle 1, a hinge of an opening 2, which is advantageously intended to protect others surrounding body parts, such as a wing 3 before, during a collision between the vehicle and an obstacle.
• the opening 2 is a closing cap of a motor compartment located at the front of the vehicle, which is a bodywork part laterally extended by front wings right and left. Only the front right wing 3 is shown in Figure 1, knowing that by symmetry with respect to a median plane extending parallel to a longitudinal axis to the vehicle, a left front wing is present.
• the hinge assembly of the opening comprises a hinge hinge 4 and a fixing bracket 5 of said hinge 4, this assembly is generally arranged in the area D, that is to say say close to a rear area of the bonnet 2.
• the motor vehicle preferably comprises two hinges 4 arranged in the area D of the vehicle, each hinge having the main function of ensuring the opening and closing of the engine compartment by moving respectively up and down the hood 2.
• the hinge 4 comprises a hinge axis A around which is able to move in rotation the cover 2.
• the hinge 4 has a low impact resistance especially when they generate transverse forces relative to the vehicle.
• the hinge 4 is provided with a lug 6 forming a stop for lateral displacement of said engine hood.
• the hinge 4 comprises a fixed part which is subsequently called fixed knuckle, which is mounted integral with the body structure of the vehicle by means of a fastening support 5.
• the mounting bracket 5 has a fixing plate 5a for the establishment of the support on an element of the body structure which is an example is a front wing liner not shown and a fixing wall 5b extending perpendicularly to the fixing plate 5a and against the wing (not shown), the end of the wall 5b being bent at 90 ° to come to rest and attach to the wing. Once fixed, this support becomes a structural element of the body.
