Description Titre de l'invention : Support de joint de capot pour véhicule automobile Description Title of the invention: Hood seal support for a motor vehicle
[1] La présente invention revendique la priorité de la demande française 2204324 déposée le 6 mai 2022, dont le contenu (texte, dessins et revendications) est ici incorporé par référence. [1] The present invention claims the priority of French application 2204324 filed on May 6, 2022, the content of which (text, drawings and claims) is herein incorporated by reference.
[2] Le contexte technique de la présente invention est celui des capots avant de véhicule automobile, et notamment des pièces de tenue de tels capots avant lorsqu’ils sont fermés. Plus particulièrement, l’invention a trait à un support de joint de capot. [2] The technical context of the present invention is that of the front hoods of motor vehicles, and in particular the parts holding such front hoods when they are closed. More particularly, the invention relates to a hood seal support.
[3] Dans l’état de la technique, on connaît des joints de capot solidaires du capot via des agrafes fixant de tels joints de capot sur une doublure de capot. On connaît aussi des joints de capot fixés solidairement à des pièces supports fixe situées en regard du capot et contre lesquelles le capot, lorsqu’il est fermé, est mis en appui. [3] In the state of the art, hood joints are known that are secured to the hood via clips fixing such hood joints to a hood lining. We also know hood gaskets fixed integrally to fixed support parts located opposite the hood and against which the hood, when closed, is placed in support.
[4] De manière connue, un capot avant de véhicule automobile doit satisfaire un grand nombre de critères de sécurité, parmi lesquels on trouve le cas d’un choc avant contre un piéton, la tête dudit piéton venant alors percuter le capot avant. Afin de limiter les dégâts causés sur la tête du piéton lors d’un tel choc, il convient de réduire l’intensité du choc. En d’autres termes, un capot avant doit permettre d’absorber au moins une partie du choc de la tête contre ledit capot avant. [4] In known manner, a front hood of a motor vehicle must satisfy a large number of safety criteria, among which we find the case of a front impact against a pedestrian, the head of said pedestrian then hitting the front hood. In order to limit the damage caused to the pedestrian's head during such an impact, the intensity of the shock should be reduced. In other words, a front hood must make it possible to absorb at least part of the impact of the head against said front hood.
[5] On constate ainsi que les capots avant connus associés aux différentes intégrations du joint de capot ne permettent pas une atténuation efficace d’un choc entre la tête d’un piéton et ledit capot. [5] We thus see that the known front hoods associated with the different integrations of the hood seal do not allow effective attenuation of an impact between the head of a pedestrian and said hood.
[6] La présente invention a pour objet de proposer un nouveau support de joint de capot afin de répondre au moins en grande partie aux problèmes précédents et de conduire en outre à d’autres avantages. [6] The object of the present invention is to propose a new hood seal support in order to at least largely address the previous problems and also lead to other advantages.
[7] Un autre but de l’invention est de réduire l’intensité d’un impact d’un piéton sur le capot avant. [7] Another aim of the invention is to reduce the intensity of a pedestrian impact on the front hood.
[8] Selon un premier aspect de l’invention, on atteint au moins l’un des objectifs précités avec un support de joint de capot pour véhicule automobile, le support de joint de capot étant destiné à être fixé solidairement à un support d’aile du véhicule automobile, le support de joint de capot comportant (i) une plateforme destinée à recevoir le joint de capot, (ii) au moins un dispositif de fixation du support de joint de capot sur le support d’aile, le dispositif de fixation étant configuré pour maintenir à distance la plateforme du support d’aile, relativement à un axe vertical, de sorte qu’une distance non nulle sépare ladite plateforme dudit support d’aile, relativement à l’axe vertical, (iii) un système d’amorce de rupture configuré pour autoriser une casse de chaque au moins un dispositif de fixation, au niveau du système d’amorce de rupture, si une force de compression de la plateforme en direction du support d’aile est supérieure à une intensité nominale de rupture. [8] According to a first aspect of the invention, at least one of the aforementioned objectives is achieved with a hood seal support for a motor vehicle, the hood seal support being intended to be fixed integrally to a hood seal support. vehicle wing automobile, the hood seal support comprising (i) a platform intended to receive the hood seal, (ii) at least one device for fixing the hood seal support on the wing support, the fixing device being configured to keep the platform at a distance from the wing support, relative to a vertical axis, so that a non-zero distance separates said platform from said wing support, relative to the vertical axis, (iii) a primer system breakage configured to authorize breakage of each at least one fixing device, at the level of the breakage initiation system, if a compressive force of the platform in the direction of the wing support is greater than a nominal breakage intensity.
[9] Dans le contexte de la présente invention, l’axe longitudinal, l’axe latéral et l’axe vertical sont définis relativement au véhicule automobile sur lequel le support de joint de capot conforme au premier aspect de l’invention est destiné à être monté. Plus particulièrement, l’axe transversal s’entend comme une direction prise entre un côté latéral du véhicule automobile et un côté latéral opposé dudit véhicule automobile. En d’autres termes, l’axe transversal s’entend selon une direction qui s’étend depuis un côté passager du véhicule automobile vers un côté conducteur dudit véhicule automobile, ou réciproquement. Les adjectifs latéraux, intérieur et extérieur font référence à un tel axe transversal. En outre, l’axe longitudinal s’étend comme étant pris le long d’une direction qui s’étend d’avant en arrière ou d’arrière en avant du véhicule automobile. L’axe longitudinal est perpendiculaire à l’axe transversal. Les adjectifs frontaux, avant et arrière font référence à cet axe longitudinal. Enfin, l’axe vertical s’entend comme étant pris le long d’un axe qui s’étend depuis les roues du véhicule automobile et vers le toit dudit véhicule automobile, ou inversement, l’axe vertical étant simultanément perpendiculaire à l’axe transversal et à l’axe longitudinal. Les adjectifs dessus et dessous, ou inférieur et supérieur font référence à cet axe vertical. [9] In the context of the present invention, the longitudinal axis, the lateral axis and the vertical axis are defined relative to the motor vehicle on which the hood seal support according to the first aspect of the invention is intended to be mounted. More particularly, the transverse axis is understood as a direction taken between a lateral side of the motor vehicle and an opposite lateral side of said motor vehicle. In other words, the transverse axis is understood in a direction which extends from a passenger side of the motor vehicle towards a driver's side of said motor vehicle, or vice versa. The adjectives lateral, interior and exterior refer to such a transverse axis. Additionally, the longitudinal axis extends as taken along a direction that extends from front to rear or rear to front of the motor vehicle. The longitudinal axis is perpendicular to the transverse axis. The adjectives frontal, front and rear refer to this longitudinal axis. Finally, the vertical axis is understood as being taken along an axis which extends from the wheels of the motor vehicle and towards the roof of said motor vehicle, or vice versa, the vertical axis being simultaneously perpendicular to the axis transverse and to the longitudinal axis. The adjectives above and below, or inferior and superior refer to this vertical axis.
[10] Dans le contexte de la présente invention, le support de joint de capot forme ainsi une interface mécanique destinée à collaborer avec le capot d’une part et le support d’aile du véhicule automobile d’autre part. Le support de joint de capot est destiné à être placé en regard du capot. Le support de joint de capot permet ainsi de combler un espace vertical situé entre le capot dans sa configuration fermée et le support d’aile du véhicule automobile. [11] La plateforme du support de joint de capot forme une plateforme d’accueil pour le joint de capot. En d’autres termes, le joint de capot est destiné à être fixé solidairement à la plateforme. La plateforme forme ainsi une surface relativement plane et s’étendant majoritairement dans un plan formé par l’axe transversal et l’axe longitudinal. [10] In the context of the present invention, the hood joint support thus forms a mechanical interface intended to collaborate with the hood on the one hand and the fender support of the motor vehicle on the other hand. The hood seal support is intended to be placed next to the hood. The hood seal support thus makes it possible to fill a vertical space located between the hood in its closed configuration and the fender support of the motor vehicle. [11] The hood gasket support platform forms a docking platform for the hood gasket. In other words, the hood seal is intended to be securely attached to the platform. The platform thus forms a relatively flat surface extending mainly in a plane formed by the transverse axis and the longitudinal axis.
[12] Dans le contexte de la présente invention, chaque dispositif de fixation permet d’établir une liaison entre le support de joint de capot conforme au premier aspect de l’invention et le support d’aile du véhicule automobile avec lequel il est destiné à collaborer. De manière particulièrement avantageuse, le dispositif de fixation permet de ménager une réserve volumique entre la plateforme et le support d’aile, de sorte que ladite plateforme soit située à distance du support d’aile sur lequel le support de joint de capot est destiné à être fixé, relativement à l’axe vertical. [12] In the context of the present invention, each fixing device makes it possible to establish a connection between the hood seal support according to the first aspect of the invention and the wing support of the motor vehicle with which it is intended to collaborate. In a particularly advantageous manner, the fixing device makes it possible to provide a volume reserve between the platform and the wing support, so that said platform is located at a distance from the wing support on which the hood joint support is intended to be fixed, relative to the vertical axis.
[13] Dans le contexte de la présente invention, le système d’amorce de rupture permet de programmer le dispositif de fixation à rompre si un effort orienté selon l’axe vertical dépasse l’intensité nominale de rupture. D’une manière générale, le système d’amorce de rupture est configuré pour localiser et concentrer des contraintes mécaniques apparaissant et se propageant dans le support de joint de capot conforme au premier aspect de l’invention, de sorte que, au niveau du système d’amorce de rupture, lesdites contraintes mécaniques conduisent à une rupture du support de joint de capot. L’invention conforme à son premier aspect permet ainsi de prédéterminer le ou les endroits auxquels le support de joint de capot sera rompu en cas de choc dont une intensité est supérieure à l’intensité nominale de rupture. [13] In the context of the present invention, the break initiation system makes it possible to program the fastening device to break if a force oriented along the vertical axis exceeds the nominal break intensity. Generally speaking, the rupture initiation system is configured to locate and concentrate mechanical stresses appearing and propagating in the hood seal support according to the first aspect of the invention, so that, at the level of the system initiation of rupture, said mechanical stresses lead to rupture of the hood seal support. The invention in accordance with its first aspect thus makes it possible to predetermine the location(s) at which the hood seal support will be broken in the event of an impact whose intensity is greater than the nominal rupture intensity.
[14] Le système d’amorce de rupture peut être mis en œuvre à différents endroits du support de joint de capot conforme au premier aspect de l’invention, comme il sera décrit ultérieurement. A minima, le système d’amorce de rupture est situé sur chaque au moins un dispositif de fixation. [14] The break initiation system can be implemented at different locations of the hood seal support in accordance with the first aspect of the invention, as will be described later. At a minimum, the break initiation system is located on each at least one fixing device.
[15] Dans le contexte de la présente invention, la force de compression est prise comme une force orientée selon l’axe vertical ou, d’une manière générale, orientée majoritairement selon une direction perpendiculaire à la plateforme. L’intensité nominale de rupture est une valeur seuil au-delà de laquelle le système d’amorce de rupture est configuré pour rompre et permettre ainsi au moins une casse du dispositif de fixation. [15] In the context of the present invention, the compressive force is taken as a force oriented along the vertical axis or, in general, oriented mainly in a direction perpendicular to the platform. The nominal breaking current is a threshold value beyond which the initiation system breakage is configured to break and thus allow at least one breakage of the fixing device.
[16] Le support de joint de capot conforme au premier aspect de l’invention permet ainsi de résoudre le problème technique en prévoyant une rupture de l’au moins un dispositif de fixation. Consécutivement, du fait de la présence de la réserve volumique entre la plateforme et le support d’aile, la plateforme est alors libre de s’enfoncer en direction du support d’aile. Cette rupture programmée permet ainsi d’atténuer l’impact du choc de la tête d’un piéton contre le capot, réduisant ainsi les dommages infligés audit piéton dans ce cas. [16] The hood seal support conforming to the first aspect of the invention thus makes it possible to resolve the technical problem by providing for a breakage of the at least one fixing device. Consecutively, due to the presence of the volume reserve between the platform and the wing support, the platform is then free to sink towards the wing support. This programmed break thus makes it possible to attenuate the impact of the impact of a pedestrian's head against the hood, thus reducing the damage inflicted on said pedestrian in this case.
[17] Dans le contexte de l’invention, la casse s’entend à minima comme une déformation, élastique ou plastique, du système d’amorce de rupture ou comme une désolidarisation, partielle ou totale de la plateforme par rapport au support d’aile avec lequel le support de joint de capot est destiné à collaborer. Ainsi, la casse permet, une fois intervenue, d’autoriser un mouvement relatif de la plateforme par rapport au support d’aile, relativement à l’axe vertical. [17] In the context of the invention, breakage is understood at least as an elastic or plastic deformation of the rupture initiation system or as a partial or total separation of the platform from the support. wing with which the hood seal support is intended to collaborate. Thus, the breakage allows, once intervened, to authorize relative movement of the platform in relation to the wing support, relative to the vertical axis.
[18] Le support de joint de capot conforme au premier aspect de l’invention comprend avantageusement au moins un des perfectionnements ci-dessous, les caractéristiques techniques formant ces perfectionnements pouvant être prises seules ou en combinaison : [18] The hood seal support conforming to the first aspect of the invention advantageously comprises at least one of the improvements below, the technical characteristics forming these improvements being able to be taken alone or in combination:
[19] - l'intensité nominale de rupture au-delà de laquelle le système d’amorce de rupture est configuré pour casser est comprise entre 300 N et 600 N, mesurée relativement à l’axe vertical. En outre, éventuellement, le système d’amorce de rupture est configuré pour se déformer, au niveau dudit système d’amorce de rupture, si la force de compression de la plateforme en direction du support d’aile est supérieure à une force nominale de déformation. La déformation du système d’amorce de rupture est du type élastique ou plastique. La force nominale de déformation au-delà de laquelle le système d’amorce de rupture est configuré pour se déformer est comprise entre 50 N et 100 N, mesurée relativement à l’axe vertical ; [19] - the nominal breaking intensity beyond which the breaking initiator system is configured to break is between 300 N and 600 N, measured relative to the vertical axis. Furthermore, optionally, the rupture initiation system is configured to deform, at said rupture initiation system, if the compressive force of the platform in the direction of the wing support is greater than a nominal force of deformation. The deformation of the rupture initiation system is of the elastic or plastic type. The nominal deformation force beyond which the rupture initiation system is configured to deform is between 50 N and 100 N, measured relative to the vertical axis;
[20] - le support de joint de capot conforme au premier aspect de l’invention comporte avantageusement deux dispositifs de fixation. Les dispositifs de fixation sont préférentiellement alignés le long de l’axe longitudinal afin de permettre une fixation stable du support de joint sur le support d’aile ; [20] - the hood seal support according to the first aspect of the invention advantageously comprises two fixing devices. Fixing devices are preferably aligned along the longitudinal axis in order to allow stable attachment of the joint support to the wing support;
[21] - chaque au moins un dispositif de fixation prend la forme d’une pontée qui s’étend en saillie depuis la plateforme, chaque pontée comportant au moins une portée s’élançant depuis la plateforme et une face d’appui située au niveau d’une extrémité de l’au moins une portée distale de la plateforme. L’au moins une portée de chaque pontée prend la forme d’une paroi qui s’étend depuis une face inférieure de la plateforme, située en regard du support d’aile. De manière avantageuse, la paroi formant la portée comporte une première portion qui s’étend depuis la plateforme et une deuxième portion qui s’étend dans le prolongement de la première portion. La deuxième portion de la paroi formant la portée forme un angle non nul avec la première portion de ladite paroi, par exemple compris entre 20° et 60°. Cette configuration avantageuse permet de faciliter un écrasement de la pontée en cas de choc supérieur à l’intensité nominale de rupture. La première portion de la paroi formant la portée forme un angle compris entre 60° et 120° avec la face inférieure de la plateforme ; [21] - each at least one fixing device takes the form of a deck which extends projecting from the platform, each deck comprising at least one span extending from the platform and a support face located at the level of one end of the at least one distal reach of the platform. The at least one span of each deck takes the form of a wall which extends from a lower face of the platform, located opposite the wing support. Advantageously, the wall forming the span comprises a first portion which extends from the platform and a second portion which extends in the extension of the first portion. The second portion of the wall forming the span forms a non-zero angle with the first portion of said wall, for example between 20° and 60°. This advantageous configuration makes it easier to crush the deck in the event of an impact greater than the nominal breaking intensity. The first portion of the wall forming the span forms an angle of between 60° and 120° with the lower face of the platform;
[22] - chaque au moins une pontée comporte un évidement central délimité latéralement par l’au moins une portée, et verticalement par la face inférieure de la plateforme d’une part, et par la face d’appui de la pontée d’autre part. En d’autres termes, chaque pontée formant l’au moins un dispositif de fixation prend la forme d’une structure creuse formée par des parois ménageant l’évidement central entre elles afin d’autoriser un écrasement de la pontée en cas de choc sur la plateforme supérieur à l’intensité nominale de rupture ; [22] - each at least one deck has a central recess delimited laterally by the at least one span, and vertically by the lower face of the platform on the one hand, and by the support face of the deck on the other go. In other words, each deck forming the at least one fixing device takes the form of a hollow structure formed by walls providing the central recess between them in order to allow crushing of the deck in the event of an impact on the platform exceeds the nominal breaking intensity;
[23] - préférentiellement, chaque pontée comporte deux portées situées en regard l’une de l’autre et de part et d’autre de la face d’appui. Cette configuration permet d’améliorer la tenue de la plateforme à l’aplomb du support d’aile avec lequel le support de joint de capot est destiné à collaborer ; [23] - preferably, each deck has two spans located opposite each other and on either side of the support face. This configuration makes it possible to improve the holding of the platform directly above the wing support with which the hood joint support is intended to collaborate;
[24] - dans un plan comportant l’axe vertical, chaque pontée présente un profil transverse de forme générale en U ou en V ; [24] - in a plane including the vertical axis, each deck has a transverse profile of general U or V shape;
[25] - chaque au moins une portée de la pontée formant l’au moins un dispositif de fixation présente un amincissement local de matière formant le système d’amorce de rupture. L’amincissement local permet ainsi de localiser les contraintes mécaniques apparaissant et se propageant dans le support de joint de capot, notamment au travers de chaque au moins un dispositif de fixation ; [25] - each at least one span of the deck forming the at least one fixing device has a local thinning of material forming the rupture initiation system. Local thinning thus makes it possible to locate the constraints mechanical forces appearing and propagating in the hood seal support, in particular through each at least one fixing device;
[26] - chaque amincissement local de matière prend la forme d’un col dont un profil est choisi parmi un profil circulaire ou elliptique ou semi-circulaire ou semi-elliptique de l’au moins une portée ; [26] - each local thinning of material takes the form of a neck whose profile is chosen from a circular or elliptical or semi-circular or semi-elliptical profile of the at least one span;
[27] - chaque amincissement local de matière formant le système d’amorce de rupture présente, au niveau d’une partie de l’au moins une portée de moindre épaisseur, une épaisseur comprise entre 20% et 50% de l’épaisseur de la portée. En particulier, l’amincissement local de matière formant le système d’amorce de rupture présente, au niveau de la partie de l’au moins une portée de moindre épaisseur, une épaisseur comprise entre 0,5 mm et 1 mm ; [27] - each local thinning of material forming the rupture initiation system has, at a part of the at least one span of lesser thickness, a thickness of between 20% and 50% of the thickness of the scope. In particular, the local thinning of material forming the rupture initiation system has, at the level of the part of the at least one bearing of lesser thickness, a thickness of between 0.5 mm and 1 mm;
[28] - chaque pontée est issue de matière avec la plateforme. D’une manière générale, chaque au moins un dispositif de fixation est issu de matière avec la plateforme. On entend par « issu de matière » le fait que l’au moins un dispositif de fixation et la plateforme ne peuvent être séparés les uns des autres sans qu’il ne soit porté atteinte à tout ou partie de leur intégrité. Ainsi, dans le support de joint de capot selon l’invention, chaque au moins un dispositif de fixation et la plateforme forment un ensemble monobloc du fait qu’ils ne forment ensemble qu’une seule et même pièce continue, faite d’un seul tenant et obtenue au cours d’un même procédé de fabrication ; [28] - each deck comes from material with the platform. Generally speaking, each at least one fixing device comes from the material with the platform. By “made from material” we mean the fact that the at least one fixing device and the platform cannot be separated from each other without compromising all or part of their integrity. Thus, in the hood seal support according to the invention, each at least one fixing device and the platform form a one-piece assembly due to the fact that together they form only one and the same continuous part, made of a single piece. holding and obtained during the same manufacturing process;
[29] - le support de joint de capot comporte en outre au moins un dispositif de stabilisation du support de joint de capot sur le support d’aile, chaque dispositif de stabilisation comportant une patte qui s’étend en saillie depuis la plateforme en direction du support d’aile, la patte présentant, au niveau d’une extrémité libre distale de la plateforme, une face de contact destinée à être mise en appui du support d’aile. Ainsi, l’au moins un dispositif de stabilisation permet de renforcer la tenue et la stabilité du support de joint de capot sur le support d’aile du véhicule automobile avec lequel il est destiné à collaborer. Chaque au moins un dispositif de stabilisation propose ainsi une reprise d’efforts pour le support de joint de capot, permettant d’éviter que ledit support de joint de capot ne bascule ou ne glisse. En particulier, de manière particulièrement avantageuse, chaque au moins un dispositif de stabilisation est configuré pour stabiliser le support de joint de capot par rapport au support d’aile, relativement à une translation selon l’axe transversale et/ou une rotation du support de joint de capot autour de l’axe longitudinal. Cette configuration est particulièrement avantageuse car le support de joint de capot conforme au premier aspect de l’invention est destiné à être monté en porte-à-faux sur le support d’aile, une partie du support de joint de capot se trouvant au-dessus d’une dépression du support d’aile et nécessitant une reprise d’effort pour en stabiliser l’appui et éviter un basculement. En effet, lors de la fermeture du capot, il est nécessaire de garantir une bonne stabilité du support de joint de capot afin de garantir le bon positionnement du joint de capot relativement au capot : l’au moins un dispositif de stabilisation permet ainsi de maintenir la position initiale du support de joint de capot conforme au premier aspect de l’invention et permet, in fine, d’assurer une bonne étanchéité entre le capot fermé et le support de joint de capot ; [29] - the hood joint support further comprises at least one device for stabilizing the hood joint support on the wing support, each stabilizing device comprising a tab which extends projecting from the platform in the direction of the wing support, the tab having, at a distal free end of the platform, a contact face intended to be placed in support of the wing support. Thus, the at least one stabilization device makes it possible to reinforce the strength and stability of the hood seal support on the wing support of the motor vehicle with which it is intended to collaborate. Each at least one stabilization device thus offers a recovery of forces for the hood seal support, making it possible to prevent said hood seal support from tilting or sliding. In particular, in a particularly advantageous manner, each at least one stabilizing device is configured to stabilize the hood seal support relative to the wing support, relative to a translation along the transverse axis and/or a rotation of the hood seal support around the longitudinal axis. This configuration is particularly advantageous because the hood seal support according to the first aspect of the invention is intended to be mounted cantilevered on the wing support, a part of the hood seal support being located above above a depression in the wing support and requiring a recovery of force to stabilize the support and avoid tilting. Indeed, when closing the hood, it is necessary to guarantee good stability of the hood seal support in order to guarantee the correct positioning of the hood seal relative to the hood: the at least one stabilizing device thus makes it possible to maintain the initial position of the hood seal support conforms to the first aspect of the invention and allows, ultimately, to ensure a good seal between the closed hood and the hood seal support;
[30] - chaque au moins un dispositif de stabilisation est situé au niveau d’un bord périphérique de la plateforme. En particulier, chaque au moins un dispositif de stabilisation est situé au niveau du bord périphérique de la plateforme destiné à être situé du côté d’un compartiment moteur lorsque le support de joint de capot est monté sur le véhicule automobile ; [30] - each at least one stabilization device is located at a peripheral edge of the platform. In particular, each at least one stabilizing device is located at the peripheral edge of the platform intended to be located on the side of an engine compartment when the hood seal support is mounted on the motor vehicle;
[31] - chaque patte formant l’au moins un dispositif de stabilisation comporte un premier segment du côté de la plateforme et un deuxième segment situé dans le prolongement du premier segment, une épaisseur du deuxième segment, mesurée selon un axe transversal, étant inférieure à l’épaisseur du premier segment, une variation d’épaisseur entre le premier segment et le deuxième segment formant le système d’amorce de rupture. Cette configuration avantageuse permet de garantir une casse de chaque dispositif de stabilisation en cas de choc sur le capot supérieur à l’intensité nominale de rupture. D’une manière générale, relativement à l’axe vertical, une épaisseur de chaque patte est, au niveau d’une extrémité distale de la plateforme, inférieure à une épaisseur de chaque patte prise au niveau d’une partie proximale de ladite plateforme. La variation d’épaisseur de chaque patte formant l’au moins un dispositif de stabilisation peut être continue ou, préférentiellement, discontinue ; [31] - each tab forming the at least one stabilization device comprises a first segment on the side of the platform and a second segment located in the extension of the first segment, a thickness of the second segment, measured along a transverse axis, being less to the thickness of the first segment, a variation in thickness between the first segment and the second segment forming the rupture initiation system. This advantageous configuration makes it possible to guarantee breakage of each stabilizing device in the event of an impact on the cover greater than the nominal breakage intensity. Generally speaking, relative to the vertical axis, a thickness of each leg is, at a distal end of the platform, less than a thickness of each leg taken at a proximal part of said platform. The variation in thickness of each tab forming the at least one stabilization device can be continuous or, preferably, discontinuous;
[32] - une épaisseur du deuxième segment de chaque patte formant l’au moins un dispositif de stabilisation est comprise entre 20% et 50% de l’épaisseur du premier segment. En particulier, une épaisseur du deuxième segment de chaque patte formant l’au moins un dispositif de stabilisation est comprise entre 0,5 mm et 1 mm ; [32] - a thickness of the second segment of each tab forming the at least one stabilizing device is between 20% and 50% of the thickness of the first segment. In particular, a thickness of the second segment of each tab forming the at least one stabilizing device is between 0.5 mm and 1 mm;
[33] - la plateforme comporte des ouvertures de fixation du joint de capot destinées à collaborer avec des agrafes dudit joint de capot. Dans le contexte de l’invention, les agrafes prennent la forme de n’importe quel organe de fixation, détachable ou permanent, du joint de capot sur la plateforme du support de joint de capot. Les agrafes collaborent avec les ouvertures de fixation de sorte à réaliser une telle fixation du joint de capot sur le support de joint de capot. La fixation est réalisée par emboitement ou par encliquetage ou, d’une manière générale, par collaboration de formes complémentaires. Relativement à un axe transversal, chaque au moins un dispositif de fixation est situé d’un premier côté des ouvertures de fixation ménagées sur la plateforme et chaque au moins un dispositif de stabilisation est situé d’un deuxième côté desdites ouvertures de fixation. Cette configuration avantageuse permet de garantir une bonne stabilité du support de joint de capot lorsque le capot est mis en appui contre le joint de capot solidaire du support de joint de capot conforme au premier aspect de l’invention ; [33] - the platform includes openings for fixing the hood gasket intended to collaborate with clips of said hood gasket. In the context of the invention, the clips take the form of any fixing member, detachable or permanent, of the hood seal on the platform of the hood seal support. The clips work with the fixing openings so as to achieve such attachment of the hood seal to the hood seal support. Fixing is carried out by interlocking or snap-fastening or, generally speaking, by collaboration of complementary shapes. Relative to a transverse axis, each at least one fixing device is located on a first side of the fixing openings provided on the platform and each at least one stabilizing device is located on a second side of said fixing openings. This advantageous configuration makes it possible to guarantee good stability of the hood gasket support when the hood is placed against the hood gasket secured to the hood gasket support conforming to the first aspect of the invention;
[34] - le support de joint de capot conforme au premier aspect de l’invention est préférentiellement formé d’un matériau comportant du pastique, mais il pourrait aussi être obtenu dans un matériau métallique. Les dimensions de ses différentes parties, et notamment du système d’amorce de rupture seraient alors dimensionnées en fonction du matériau choisi et au regard de son module d’élasticité. Le support de joint de capot est préférentiellement obtenu par moulage. [34] - the hood seal support according to the first aspect of the invention is preferably formed of a material comprising plastic, but it could also be obtained in a metallic material. The dimensions of its different parts, and in particular of the rupture initiation system, would then be dimensioned according to the material chosen and with regard to its modulus of elasticity. The hood seal support is preferably obtained by molding.
[35] Selon un deuxième aspect de l’invention, il est proposé un arrangement pour véhicule automobile, l’arrangement comportant (i) un support d’aile comportant une zone de fixation d’une aile de carrosserie du véhicule automobile et une dépression destinée à être située du côté d’un compartiment moteur du véhicule automobile, (ii) un support de joint de capot conforme au premier aspect de l’invention ou selon l’un quelconque de ses perfectionnements, le support de joint de capot étant fixé solidairement au support d’aile, et (iii) un joint de capot fixé solidairement au support de joint de capot. [36] Dans le contexte de l’invention, la zone de fixation de l’aile de carrosserie est située latéralement à l’extérieur de la dépression du support d’aile, relativement à l’axe transversal. En d’autres termes, la dépression est destinée à être située du côté d’un compartiment moteur du véhicule automobile.

[36] In the context of the invention, the fixing zone of the body wing is located laterally outside the depression of the wing support, relative to the transverse axis. In other words, the depression is intended to be located on the side of an engine compartment of the motor vehicle.

On pourra notamment imaginer des variantes de l’invention ne comprenant qu’une sélection de caractéristiques décrites par la suite de manière isolées des autres caractéristiques décrites, si cette sélection de caractéristiques est suffisante pour conférer un avantage technique ou pour différencier l’invention par rapport à l’état de la technique antérieur.

[48] Sur les FIGURES, les éléments communs à plusieurs FIGURES conservent la même référence. [48] On the FIGURES, elements common to several FIGURES retain the same reference.
[49] Dans les FIGURES et paragraphes suivants, l’axe longitudinal X, l’axe latéral et l’axe vertical Z sont définis relativement au véhicule automobile 7 sur lequel le support de joint de capot 1 conforme au premier aspect de l’invention est destiné à être monté, tel que visible sur la FIGURE 3. [49] In the following FIGURES and paragraphs, the longitudinal axis is intended to be mounted, as seen in FIGURE 3.
[50] Plus particulièrement, l’axe transversal Y s’entend comme une direction prise entre un côté latéral du véhicule automobile 7 et un côté latéral opposé dudit véhicule automobile 7. En d’autres termes, l’axe transversal Y s’entend selon une direction qui s’étend depuis un côté passager du véhicule automobile 7 vers un côté conducteur dudit véhicule automobile 7, ou réciproquement. Les adjectifs latéraux, intérieur et extérieur font référence à un tel axe transversal Y. [50] More particularly, the transverse axis Y is understood as a direction taken between a lateral side of the motor vehicle 7 and an opposite lateral side of said motor vehicle 7. In other words, the transverse axis Y is understood in a direction which extends from a passenger side of the motor vehicle 7 towards a driver's side of said motor vehicle 7, or vice versa. The adjectives lateral, interior and exterior refer to such a transverse axis Y.
[51] En outre, l’axe longitudinal X s’étend comme étant pris le long d’une direction qui s’étend d’avant en arrière ou d’arrière en avant du véhicule automobile 7. L’axe longitudinal X est perpendiculaire à l’axe transversal Y. Les adjectifs frontaux, avant et arrière font référence à cet axe longitudinal X. [51] Furthermore, the longitudinal axis to the transverse axis Y. The adjectives frontal, front and rear refer to this longitudinal axis X.
[52] Enfin, l’axe vertical Z s’entend comme étant pris le long d’un axe qui s’étend depuis les roues du véhicule automobile 7 et vers le toit dudit véhicule automobile 7, ou inversement, l’axe vertical Z étant simultanément perpendiculaire à l’axe transversal Y et à l’axe longitudinal X. Les adjectifs dessus et dessous, ou inférieur et supérieur font référence à cet axe vertical Z. [52] Finally, the vertical axis Z is understood as being taken along an axis which extends from the wheels of the motor vehicle 7 and towards the roof of said motor vehicle 7, or vice versa, the vertical axis Z being simultaneously perpendicular to the transverse axis Y and to the longitudinal axis X. The adjectives above and below, or lower and higher refer to this vertical axis Z.
[53] En références aux FIGURES 1 et 2, un exemple de réalisation d’un support de joint de capot 1 conforme au premier aspect de l’invention comporte : [53] With reference to FIGURES 1 and 2, an exemplary embodiment of a hood seal support 1 conforming to the first aspect of the invention comprises:
[54] - une plateforme 11 destinée à recevoir le joint de capot 2 ; [55] - au moins un dispositif de fixation 12 du support de joint de capot 1 sur le support d’aile 4, le dispositif de fixation 12 étant configuré pour maintenir à distance la plateforme 11 du support d’aile 4, relativement à un axe vertical Z, de sorte qu’une distance non nulle sépare ladite plateforme 11 dudit support d’aile 4, relativement à l’axe vertical Z, [54] - a platform 11 intended to receive the cover seal 2; [55] - at least one fixing device 12 of the hood seal support 1 on the wing support 4, the fixing device 12 being configured to keep the platform 11 at a distance from the wing support 4, relative to a vertical axis Z, so that a non-zero distance separates said platform 11 from said wing support 4, relative to the vertical axis Z,
[56] - un système d’amorce de rupture 15 configuré pour autoriser une casse de chaque au moins un dispositif de fixation 12, au niveau du système d’amorce de rupture 15, si une force de compression de la plateforme 11 en direction du support d’aile 4 est supérieure à une intensité nominale de rupture. [56] - a break initiation system 15 configured to authorize breakage of each at least one fixing device 12, at the level of the break initiation system 15, if a compressive force from the platform 11 towards the wing support 4 is greater than a nominal breaking intensity.
[57] Le support de joint de capot 1 forme ainsi une interface mécanique destinée à collaborer avec le capot 6 d’une part et le support d’aile 4 du véhicule automobile 7 d’autre part. Le support de joint de capot 1 est destiné à être placé en regard du capot 6. Le support de joint de capot 1 permet ainsi de combler un espace vertical situé entre le capot 6 dans sa configuration fermée et le support d’aile 4 du véhicule automobile 7 tout en autorisant, grâce au système d’amorce de rupture 15, de limiter une intensité d’un choc entre un piéton renversé par le véhicule automobile 7 sur lequel le support de joint de capot 1 est monté et ledit capot 6. [57] The hood seal support 1 thus forms a mechanical interface intended to collaborate with the hood 6 on the one hand and the wing support 4 of the motor vehicle 7 on the other hand. The hood seal support 1 is intended to be placed opposite the hood 6. The hood seal support 1 thus makes it possible to fill a vertical space located between the hood 6 in its closed configuration and the wing support 4 of the vehicle automobile 7 while allowing, thanks to the rupture initiator system 15, to limit the intensity of a shock between a pedestrian knocked down by the motor vehicle 7 on which the hood seal support 1 is mounted and said hood 6.
[58] La plateforme 11 du support de joint de capot 1 forme une plateforme 11 d’accueil pour le joint de capot 2, de sorte à permettre au joint de capot 2 d’être fixé solidairement à ladite plateforme 11 . La plateforme 11 forme ainsi une surface relativement plane qui s’étend majoritairement dans un plan formé par l’axe transversal Y et l’axe longitudinal X. La plateforme 11 comporte : [58] The platform 11 of the hood seal support 1 forms a receiving platform 11 for the hood seal 2, so as to allow the hood seal 2 to be fixed integrally to said platform 11. The platform 11 thus forms a relatively flat surface which extends mainly in a plane formed by the transverse axis Y and the longitudinal axis X. The platform 11 comprises:
[59] - une face supérieure 112 destinée à faire face au capot 6 et sur laquelle le joint de capot 2 est destiné à être fixé solidairement ; [59] - an upper face 112 intended to face the cover 6 and on which the cover seal 2 is intended to be fixed integrally;
[60] - une face inférieure 111 destinée à faire face au support d’aile 4. [60] - a lower face 111 intended to face the wing support 4.
[61] Complémentairement, la plateforme 11 est traversée par des ouvertures de fixation 14 qui permettent de collaborer avec des agrafes du joint de capot 2 afin de fixer solidairement ledit joint de capot 2 sur la plateforme 11 du support de joint de capot 1 . [61] Additionally, the platform 11 is crossed by fixing openings 14 which make it possible to collaborate with clips of the hood joint 2 in order to securely fix said hood joint 2 on the platform 11 of the hood joint support 1.
[62] Dans l’exemple de réalisation illustré sur la FIGURE 1 , le support de joint de capot 1 comporte deux ouvertures de fixation 14. Dans le contexte de la présente invention, le support de joint de capot 1 comporte au moins une ouverture de fixation 14. [62] In the exemplary embodiment illustrated in FIGURE 1, the hood seal support 1 has two fixing openings 14. In the context of the present invention, the hood seal support 1 comprises at least one fixing opening 14.
[63] Dans le cas où le support de joint de capot 1 comporte au moins deux ouvertures de fixation 14, lesdites ouvertures de fixation 14 sont avantageusement toutes alignées le long d’un axe d’alignement L qui s’étend majoritairement parallèlement à l’axe longitudinal X. Ces ouvertures de fixation 14 sont préférentiellement centrées avec le joint de capot 2 destiné à être monté sur le support de joint de capot 1 , relativement à l’axe transversal Y. [63] In the case where the hood seal support 1 has at least two fixing openings 14, said fixing openings 14 are advantageously all aligned along an alignment axis L which extends mainly parallel to the longitudinal axis
[64] La plateforme 11 est délimitée latéralement et longitudinalement par des bords périphériques qui comportent sur tout ou partie des rabats. [64] The platform 11 is delimited laterally and longitudinally by peripheral edges which have flaps on all or part.
[65] Dans le contexte de la présente invention, chaque dispositif de fixation 12 permet d’établir une liaison entre le support de joint de capot 1 conforme au premier aspect de l’invention et le support d’aile 4 du véhicule automobile 7 avec lequel il est destiné à collaborer. De manière particulièrement avantageuse, chaque dispositif de fixation 12 permet de ménager une réserve volumique entre la plateforme 11 et le support d’aile 4, de sorte que ladite plateforme 11 soit située à distance du support d’aile 4 sur lequel le support de joint de capot 1 est destiné à être fixé, relativement à l’axe vertical Z. [65] In the context of the present invention, each fixing device 12 makes it possible to establish a connection between the hood seal support 1 according to the first aspect of the invention and the wing support 4 of the motor vehicle 7 with which he is destined to collaborate with. In a particularly advantageous manner, each fixing device 12 makes it possible to provide a volume reserve between the platform 11 and the wing support 4, so that said platform 11 is located at a distance from the wing support 4 on which the joint support cover 1 is intended to be fixed, relative to the vertical axis Z.
[66] Cette configuration particulièrement avantageuse rend ainsi possible, en cas de choc piéton sur le capot 6 du véhicule automobile 7, de permettre à la plateforme 11 de s’enfoncer en direction du support d’aile 4, consécutivement à la casse du système d’amorce de rupture 15. Ainsi, dans le contexte de la présente invention, il est tout à fait primordial de ménager sous la plateforme 11 un évidement sans obstacles afin de pouvoir autoriser, le cas échéant, un compactage du support de joint de capot 1 , relativement à l’axe vertical Z. [66] This particularly advantageous configuration thus makes it possible, in the event of a pedestrian impact on the hood 6 of the motor vehicle 7, to allow the platform 11 to sink towards the wing support 4, following the breakage of the system rupture initiation 15. Thus, in the context of the present invention, it is entirely essential to provide under the platform 11 a recess without obstacles in order to be able to authorize, if necessary, compaction of the hood joint support 1, relative to the vertical axis Z.
[67] Comme visible sur les FIGURES 1 et 2, chaque dispositif de fixation 12 prend la forme d’une pontée 121 qui s’étend en saillie depuis la face inférieure 111 de la plateforme 11 et en direction du support d’aile 4. Chaque pontée 121 formant les dispositifs de fixation 12 comporte au moins une portée 120 s’élançant depuis la plateforme 11 et une face d’appui 124 située au niveau d’une extrémité de l’au moins une portée 120 distale de la plateforme 11. Dans l’exemple de réalisation illustré sur les FIGURES 1 et 2, chaque pontée 121 comporte exactement deux pontées 121 qui se font face, relativement à l’axe longitudinal X ou à l’axe transversal Y. [67] As visible in FIGURES 1 and 2, each fixing device 12 takes the form of a deck 121 which extends projecting from the lower face 111 of the platform 11 and towards the wing support 4. Each deck 121 forming the fixing devices 12 comprises at least one span 120 projecting from the platform 11 and a support face 124 located at one end of the at least one span 120 distal to the platform 11. In the exemplary embodiment illustrated in FIGURES 1 and 2, each deck 121 has exactly two bridges 121 which face each other, relative to the longitudinal axis X or the transverse axis Y.
[68] De manière avantageuse, une première pontée 121 présente un plan de symétrie qui s’étend le long de l’axe longitudinal X et de l’axe vertical Z, et une deuxième pontée 121 présente un plan de symétrie qui s’étend le long de l’axe transversal Y et de l’axe vertical Z. [68] Advantageously, a first deck 121 has a plane of symmetry which extends along the longitudinal axis X and the vertical axis Z, and a second deck 121 has a plane of symmetry which extends along the transverse Y axis and the vertical Z axis.
[69] Chaque portée 120 prend ainsi la forme d’une paroi qui s’étend depuis la face inférieure 111 de la plateforme 11. De manière avantageuse, la paroi formant la portée 120 comporte une première portion 123 qui s’étend depuis la plateforme 11 et une deuxième portion 122 qui s’étend dans le prolongement de la première portion 123. La deuxième portion 122 de la paroi forme la portée 120 forme un angle non nul avec la première portion 123 de ladite paroi, par exemple compris entre 20° et 60°. Cette configuration avantageuse permet de faciliter un écrasement de la pontée 121 en cas de choc supérieur à l’intensité nominale de rupture. La première portion 123 de la paroi formant la portée 120 forme un angle compris entre 60° et 120° avec la face inférieure 111 de la plateforme 11 . [69] Each span 120 thus takes the form of a wall which extends from the lower face 111 of the platform 11. Advantageously, the wall forming the span 120 comprises a first portion 123 which extends from the platform 11 and a second portion 122 which extends in the extension of the first portion 123. The second portion 122 of the wall forms the span 120 forms a non-zero angle with the first portion 123 of said wall, for example between 20° and 60°. This advantageous configuration makes it easier to crush the deck 121 in the event of an impact greater than the nominal rupture intensity. The first portion 123 of the wall forming the span 120 forms an angle of between 60° and 120° with the lower face 111 of the platform 11.
[70] Les parois formant les portées 120 de chaque pontée 121 sont d’épaisseur constante, en dehors d’une zone formant le système d’amorce de rupture 15 et qui sera détaillé ultérieurement. [70] The walls forming the spans 120 of each deck 121 are of constant thickness, apart from a zone forming the rupture initiation system 15 and which will be detailed later.
[71] Afin de faciliter leur rupture et/ou leur écrasement et/ou leur déformation, chaque pontée 121 comporte un évidement central délimité latéralement par les portées 120, et verticalement par la face inférieure 111 de la plateforme 11 d’une part, et par la face d’appui 124 de la pontée 121 d’autre part. [71] In order to facilitate their rupture and/or their crushing and/or their deformation, each deck 121 comprises a central recess delimited laterally by the supports 120, and vertically by the lower face 111 of the platform 11 on the one hand, and by the support face 124 of the deck 121 on the other hand.
[72] D’une manière générale, dans un plan comportant l’axe vertical Z, chaque pontée 121 présente un profil transverse de forme générale en U ou en V. [72] Generally speaking, in a plane comprising the vertical axis Z, each deck 121 has a transverse profile of general U or V shape.
[73] Dans l’exemple de réalisation illustré sur les FIGURES 1 et 2, les deux pontées 121 présentent une même hauteur, prise selon l’axe vertical Z, de sorte que la face d’appui 124 de chaque pontée 121 est située à une même distance, mesurée selon l’axe vertical Z, de la face inférieure 111 de la plateforme 11 . [73] In the exemplary embodiment illustrated in FIGURES 1 and 2, the two decks 121 have the same height, taken along the vertical axis Z, so that the support face 124 of each deck 121 is located at the same distance, measured along the vertical axis Z, from the lower face 111 of the platform 11.
[74] Afin de permettre la fixation du support de joint de capot 1 sur le support d’aile 4, le support de joint de capot 1 comporte un organe de fixation 16 situé au niveau de la face d’appui 124 de chaque pontée 121. L’organe de fixation 16 s’étend en saillie de la face d’appui 124, relativement à l’axe vertical Z et est destiné à collaborer avec des ouvertures correspondantes ménagées sur le support d’aile 4, afin de permettre une fixation par engagement de formes complémentaires. [74] In order to allow the hood joint support 1 to be fixed on the wing support 4, the hood joint support 1 comprises a fixing member 16 located at the level of the bearing face 124 of each deck 121 The fixing member 16 extends in projection of the support face 124, relative to the vertical axis Z and is intended to collaborate with corresponding openings provided on the wing support 4, in order to allow fixing by engagement of complementary shapes.
[75] Afin de renforcer la tenue et la stabilité du support de joint de capot 1 sur le support d’aile 4 du véhicule automobile 7 avec lequel il est destiné à collaborer, le support de joint de capot 1 comporte en outre au moins un dispositif de stabilisation 13 du support de joint de capot 1 sur le support d’aile 4, chaque dispositif de stabilisation 13 comportant une patte 131 qui s’étend en saillie depuis la plateforme 11 en direction du support d’aile 4, la patte 131 présentant, au niveau d’une extrémité libre distale de la plateforme 11 , une face de contact 134 destinée à être mise en appui du support d’aile 4. [75] In order to reinforce the hold and stability of the hood seal support 1 on the wing support 4 of the motor vehicle 7 with which it is intended to collaborate, the hood seal support 1 further comprises at least one stabilizing device 13 of the hood joint support 1 on the wing support 4, each stabilizing device 13 comprising a tab 131 which extends projecting from the platform 11 towards the wing support 4, the tab 131 presenting, at a free distal end of the platform 11, a contact face 134 intended to be placed in support of the wing support 4.
[76] Chaque dispositif de stabilisation 13 propose ainsi une reprise d’efforts pour le support de joint de capot 1 , permettant d’éviter que ledit support de joint de capot 1 ne bascule ou ne glisse. En particulier, de manière particulièrement avantageuse, chaque au moins un dispositif de stabilisation 13 est configuré pour stabiliser le support de joint de capot 1 par rapport au support d’aile 4, relativement à une translation selon l’axe transversal Y et/ou une rotation du support de joint de capot 1 autour de l’axe longitudinal X. Cette configuration est particulièrement avantageuse car le support de joint de capot 1 conforme au premier aspect de l’invention est destiné à être monté en porte-à-faux sur le support d’aile 4, comme visible sur les FIGURES 3 et 4, une partie du support de joint de capot 1 se trouvant au-dessus d’une dépression 42 du support d’aile 4 et nécessitant une reprise d’effort pour en stabiliser l’appui et éviter un basculement. [76] Each stabilizing device 13 thus offers a recovery of forces for the hood seal support 1, making it possible to prevent said hood seal support 1 from tilting or sliding. In particular, in a particularly advantageous manner, each at least one stabilization device 13 is configured to stabilize the hood joint support 1 relative to the wing support 4, relative to a translation along the transverse axis Y and/or a rotation of the hood seal support 1 around the longitudinal axis wing support 4, as visible in FIGURES 3 and 4, a part of the hood joint support 1 being above a depression 42 of the wing support 4 and requiring a recovery of force to stabilize it support and avoid tipping.
[77] Chaque dispositif de stabilisation 13 est situé au niveau d’un bord périphérique de la plateforme 11. En particulier, chaque au moins un dispositif de stabilisation 13 est situé au niveau du bord périphérique de la plateforme 11 destiné à être situé du côté d’un compartiment moteur lorsque le support de joint de capot 1 est monté sur le véhicule automobile 7. [77] Each stabilization device 13 is located at a peripheral edge of the platform 11. In particular, each at least one stabilization device 13 is located at the peripheral edge of the platform 11 intended to be located on the side of an engine compartment when the hood seal support 1 is mounted on the motor vehicle 7.
[78] Dans l’exemple de réalisation illustré sur les FIGURES 1 et 2, chaque dispositif de stabilisation 13 prend la forme d’un patte 131 qui s’étend en saillie depuis la face inférieure 111 de la plateforme 11 et relativement à l’axe vertical Z. En particulier, chaque patte 131 de fixation s’étend dans le prolongement du bord périphérique de la plateforme 11. D’une manière générale, chaque dispositif de stabilisation 13 est situé latéralement le plus loin possible de l’axe d’alignement L des ouvertures de fixation 14 du support de joint de capot 1 , de sorte à minimiser le risque de basculement et/ou de pivotement du support de joint de capot 1 autour de l’axe longitudinal X. [78] In the exemplary embodiment illustrated in FIGURES 1 and 2, each stabilizing device 13 takes the form of a tab 131 which extends projecting from the lower face 111 of the platform 11 and relative to the vertical axis Z. In particular, each fixing tab 131 extends in the extension of the edge peripheral of the platform 11. Generally speaking, each stabilizing device 13 is located laterally as far as possible from the alignment axis L of the fixing openings 14 of the hood seal support 1, so as to minimize the risk of tilting and/or pivoting of the hood seal support 1 around the longitudinal axis X.
[79] Dans l’exemple de réalisation illustré sur les FIGURES 1 et 2, le support de joint de capot 1 comporte deux dispositifs de stabilisation 13. Relativement à l’axe longitudinal X, les deux dispositifs de stabilisation 13 sont situés dans une position intermédiaire entre les deux dispositifs de fixation 12 du support de joint de capot 1. [79] In the exemplary embodiment illustrated in FIGURES 1 and 2, the hood seal support 1 comprises two stabilizing devices 13. Relative to the longitudinal axis X, the two stabilizing devices 13 are located in a position intermediate between the two fixing devices 12 of the hood seal support 1.
[80] Complémentairement, relativement à l’axe transversal Y, chaque dispositif de fixation 12 est situé d’un premier côté P1 de l’axe d’alignement L des ouvertures de fixation 14 ménagées sur la plateforme 11 , et chaque dispositif de stabilisation 13 est situé d’un deuxième côté P2 desdites ouvertures de fixation 14. [80] Complementarily, relative to the transverse axis Y, each fixing device 12 is located on a first side P1 of the alignment axis L of the fixing openings 14 provided on the platform 11, and each stabilizing device 13 is located on a second side P2 of said fixing openings 14.
[81] Cette configuration avantageuse permet de garantir une bonne stabilité du support de joint de capot 1 lorsque le capot 6 est mis en appui contre le joint de capot 2 solidaire du support de joint de capot 1 conforme au premier aspect de l’invention, dans la mesure où le joint de capot 2 est destiné à s’étendre longitudinalement dans une position intermédiaire entre les dispositifs de fixation 12 et les dispositifs de stabilisation 13 du support de joint de capot 1 , relativement à l’axe transversal Y. [81] This advantageous configuration makes it possible to guarantee good stability of the hood seal support 1 when the hood 6 is placed against the hood seal 2 secured to the hood seal support 1 in accordance with the first aspect of the invention, insofar as the hood seal 2 is intended to extend longitudinally in an intermediate position between the fixing devices 12 and the stabilizing devices 13 of the hood seal support 1, relative to the transverse axis Y.
[82] Afin d’autoriser une rupture programmée de chaque dispositif de fixation 12 et/ou de chaque dispositif de stabilisation 13, le système d’amorce de rupture 15 du support de joint de capot 1 intègre respectivement au(x) dispositif(s) de fixation et/ou au(x) dispositif(s) de stabilisation des dispositions qui permettent de programmer une rupture de ceux-ci lorsqu’une force d’impact orientée selon l’axe vertical Z apparaissant sur la plateforme 11 dépasse l’intensité nominale de rupture. En d’autres termes, le système d’amorce de rupture 15 est programmé pour céder si une force orientée selon l’axe vertical Z et s’appliquant sur la plateforme 11 génère, au niveau de chaque système d’amorce de rupture 15, des contraintes mécaniques dont l’intensité est supérieure à l’intensité nominale de rupture. [83] Dans le contexte de l’invention, l’intensité nominale de rupture est comprise entre 300 N et 600 N. [82] In order to authorize a programmed rupture of each fixing device 12 and/or each stabilizing device 13, the rupture initiation system 15 of the hood seal support 1 integrates respectively into the device(s). ) of fixing and/or to the stabilization device(s) of the provisions which make it possible to program a rupture of these when an impact force oriented along the vertical axis Z appearing on the platform 11 exceeds the rated breaking intensity. In other words, the rupture initiation system 15 is programmed to give way if a force oriented along the vertical axis Z and applying to the platform 11 generates, at the level of each rupture initiation system 15, mechanical stresses whose intensity is greater than the nominal breaking intensity. [83] In the context of the invention, the nominal breaking intensity is between 300 N and 600 N.
[84] Complémentairement ou alternativement, afin d’autoriser une déformation programmée de chaque dispositif de fixation 12 et/ou de chaque dispositif de stabilisation 13, le système d’amorce de rupture 15 du support de joint de capot 1 intègre respectivement au(x) dispositif(s) de fixation et/ou au(x) dispositif(s) de stabilisation des dispositions qui permettent de programmer une rupture de ceux- ci lorsqu’une force d’impact orientée selon l’axe vertical Z apparaissant sur la plateforme 11 dépasse une intensité nominale de déformation. En d’autres termes, le système d’amorce de rupture 15 est programmé pour céder si une force orientée selon l’axe vertical Z et s’appliquant sur la plateforme 11 génère, au niveau de chaque système d’amorce de rupture 15, des contraintes mécaniques dont l’intensité est supérieure à l’intensité nominale de déformation. La déformation du système d’amorce de rupture 15 est du type d’une déformation élastique ou plastique. [84] Complementarily or alternatively, in order to authorize a programmed deformation of each fixing device 12 and/or each stabilizing device 13, the rupture initiation system 15 of the hood seal support 1 integrates respectively with the(x ) fixing device(s) and/or stabilization device(s) of the provisions which make it possible to program a rupture of the latter when an impact force oriented along the vertical axis Z appearing on the platform 11 exceeds a nominal strain intensity. In other words, the rupture initiation system 15 is programmed to give way if a force oriented along the vertical axis Z and applying to the platform 11 generates, at the level of each rupture initiation system 15, mechanical stresses whose intensity is greater than the nominal deformation intensity. The deformation of the rupture initiation system 15 is of the type of elastic or plastic deformation.
[85] Dans le contexte de l’invention, l’intensité nominale de déformation est comprise entre 50 N et 100 N. [85] In the context of the invention, the nominal strain intensity is between 50 N and 100 N.
[86] Dans le contexte de l’invention, le système d’amorce de rupture 15 est configuré pour prédéterminer une zone géographique de rupture du support de joint de capot 1 , et préférentiellement des dispositifs de fixation 12 et/ou des dispositifs de stabilisation 13. [86] In the context of the invention, the rupture initiation system 15 is configured to predetermine a geographical zone of rupture of the hood seal support 1, and preferably of the fixing devices 12 and/or stabilizing devices 13.
[87] A cet effet, chaque portée 120 de la pontée 121 formant le ou les dispositifs de fixation 12 présente un amincissement local de matière 151 formant le système d’amorce de rupture 15. Chaque amincissement local de matière 151 prend la forme d’un col dont un profil est choisi parmi un profil circulaire ou elliptique ou semi-circulaire ou semi-elliptique. Plus particulièrement, chaque amincissement local de matière 151 formant le système d’amorce de rupture 15 présente, au niveau d’une partie de l’au moins une portée 120 de moindre épaisseur, une épaisseur comprise entre 20% et 50% de l’épaisseur de la portée 120. En particulier, l’amincissement local de matière 151 formant le système d’amorce de rupture 15 présente, au niveau de la partie de l’au moins une portée 120 de moindre épaisseur, une épaisseur comprise entre 0,5 mm et 1 mm. L’épaisseur est ici considérée selon la plus petite dimension de la portée 120, prise selon l’axe longitudinal X ou l’axe transversal Y. [87] For this purpose, each span 120 of the deck 121 forming the fixing device(s) 12 has a local thinning of material 151 forming the rupture initiation system 15. Each local thinning of material 151 takes the form of a neck whose profile is chosen from a circular or elliptical or semi-circular or semi-elliptical profile. More particularly, each local thinning of material 151 forming the rupture initiation system 15 has, at a part of the at least one surface 120 of lesser thickness, a thickness of between 20% and 50% of the thickness of the bearing 120. In particular, the local thinning of material 151 forming the rupture initiation system 15 has, at the level of the part of the at least one bearing 120 of lesser thickness, a thickness of between 0, 5mm and 1mm. Thickness is here considered according to the smallest dimension of the span 120, taken along the longitudinal axis X or the transverse axis Y.
[88] Comme visible sur les FIGURES 1 et 2, les amincissements locaux de matière 151 sont formés sur chaque portée 120 au niveau de leur première portion 123, et en particulier au niveau d’une extrémité de ladite première portion 123 distale de la plateforme 11 , à proximité de la deuxième portion 122. [88] As visible in FIGURES 1 and 2, the local thinnings of material 151 are formed on each bearing 120 at the level of their first portion 123, and in particular at the level of one end of said first portion 123 distal to the platform 11, near the second portion 122.
[89] Pour un dispositif de fixation 12 donné, les amincissements locaux de matière 151 sont préférentiellement localisés aux mêmes endroits sur chaque portée 120. En outre, pour un dispositif de fixation 12 donné, les amincissements locaux de matière 151 présentent des dimensions et/ou des formes qui sont préférentiellement identiques. [89] For a given fastening device 12, the local thinnings of material 151 are preferentially located at the same locations on each bearing 120. In addition, for a given fastening device 12, the local thinnings of material 151 have dimensions and/or or shapes which are preferably identical.
[90] Complémentairement ou alternativement, chaque patte 131 formant le ou les dispositifs de stabilisation 13 comporte un premier segment 133 du côté de la plateforme 11 et un deuxième segment 132 situé dans le prolongement du premier segment 133, une épaisseur du deuxième segment 132, mesurée selon un axe transversal Y, étant inférieure à l’épaisseur du premier segment 133, une variation d’épaisseur 152 entre le premier segment 133 et le deuxième segment 132 formant le système d’amorce de rupture 15. [90] Complementarily or alternatively, each tab 131 forming the stabilizing device(s) 13 comprises a first segment 133 on the side of the platform 11 and a second segment 132 located in the extension of the first segment 133, a thickness of the second segment 132, measured along a transverse axis Y, being less than the thickness of the first segment 133, a variation in thickness 152 between the first segment 133 and the second segment 132 forming the rupture initiation system 15.
[91] D’une manière générale, relativement à l’axe vertical Z, une épaisseur de chaque patte 131 est, au niveau d’une extrémité distale de la plateforme 11 , inférieure à une épaisseur de chaque patte 131 prise au niveau d’une partie proximale de ladite plateforme 11 . [91] Generally speaking, relative to the vertical axis Z, a thickness of each tab 131 is, at the level of a distal end of the platform 11, less than a thickness of each tab 131 taken at the level of a proximal part of said platform 11.
[92] La variation d’épaisseur 152 de la patte 131 formant chaque dispositif de stabilisation 13 peut être continue ou, préférentiellement, discontinue. [92] The variation in thickness 152 of the tab 131 forming each stabilizing device 13 can be continuous or, preferably, discontinuous.
[93] Une épaisseur du deuxième segment 132 de la patte 131 formant chaque dispositif de stabilisation 13 est comprise entre 20% et 50% de l’épaisseur du premier segment 133. En particulier, une épaisseur du deuxième segment 132 de la patte 131 formant chaque dispositif de stabilisation 13 est comprise entre 0,5 mm et 1 mm. [93] A thickness of the second segment 132 of the tab 131 forming each stabilizing device 13 is between 20% and 50% of the thickness of the first segment 133. In particular, a thickness of the second segment 132 of the tab 131 forming each stabilizing device 13 is between 0.5 mm and 1 mm.
[94] Bien entendu, le support de joint de capot 1 est particulièrement adapté à une intégration sur un véhicule automobile 7, le support de joint de capot 1 étant destiné à être fixé solidairement à un support d’aile 4 du véhicule automobile 7, à accueillir un joint de capot 2 sur sa plateforme 11 , et à être mis en compression par le capot 6 lorsque celui-ci est fermé et écrase le joint de capot 2 contre ladite plateforme 11. [94] Of course, the hood seal support 1 is particularly suitable for integration on a motor vehicle 7, the hood seal support 1 being intended to be fixed integrally to a wing support 4 of the motor vehicle 7, to welcome a hood seal 2 on its platform 11, and to be put in compression by the hood 6 when the latter is closed and crushes the hood gasket 2 against said platform 11.
[95] En référence aux FIGURES 3 et 4, l’invention concerne aussi un arrangement 5 pour véhicule automobile 7, l’arrangement comportant : [95] With reference to FIGURES 3 and 4, the invention also relates to an arrangement 5 for a motor vehicle 7, the arrangement comprising:
[96] - un support d’aile 4 comportant une zone de fixation 41 d’une aile de carrosserie 3 du véhicule automobile 7 et une dépression 42 destinée à être située du côté d’un compartiment moteur du véhicule automobile 7, [96] - a wing support 4 comprising a fixing zone 41 of a body wing 3 of the motor vehicle 7 and a depression 42 intended to be located on the side of an engine compartment of the motor vehicle 7,
[97] - un support de joint de capot 1 conforme au premier aspect de l’invention et tel que décrit précédemment, le support de joint de capot 1 étant fixé solidairement au support d’aile 4, et [97] - a hood joint support 1 conforming to the first aspect of the invention and as described previously, the hood joint support 1 being fixed integrally to the wing support 4, and
[98] - un joint de capot 2 fixé solidairement au support de joint de capot 1 . [98] - a hood gasket 2 integrally fixed to the hood gasket support 1.
[99] La zone de fixation 41 de l’aile de carrosserie 3 est située latéralement à l’extérieur de la dépression 42 du support d’aile 4, relativement à l’axe transversal Y. En d’autres termes, la dépression 42 est destinée à être située du côté d’un compartiment moteur du véhicule automobile 7. [99] The fixing zone 41 of the body wing 3 is located laterally outside the depression 42 of the wing support 4, relative to the transverse axis Y. In other words, the depression 42 is intended to be located on the side of an engine compartment of the motor vehicle 7.
[100] Chaque au moins un dispositif de fixation 12 est en appui sur la zone de fixation 41 de l’aile de carrosserie 3, et chaque au moins un dispositif de stabilisation 13 est en appui contre la dépression 42. [100] Each at least one fixing device 12 rests on the fixing zone 41 of the body wing 3, and each at least one stabilization device 13 rests against the depression 42.
[101] Enfin, la FIGURE 3 illustre l’intégration d’un tel arrangement 5 sur un véhicule automobile 7, le capot 6 avant du véhicule automobile 7 comprimant le joint de capot 2 contre le support de joint de capot 1 lorsque ledit capot 6 avant est fermé. L’arrangement 5 est situé à proximité d’un passage de roue 31 du véhicule automobile 7. [101] Finally, FIGURE 3 illustrates the integration of such an arrangement 5 on a motor vehicle 7, the front hood 6 of the motor vehicle 7 compressing the hood seal 2 against the hood seal support 1 when said hood 6 front is closed. The arrangement 5 is located near a wheel arch 31 of the motor vehicle 7.
[102] En synthèse, l’invention concerne un support de joint de capot 1 présentant une plateforme 11 de fixation d’un joint de capot 2, le support comportant un dispositif de fixation 12 sur un support d’aile 4 de véhicule automobile 7 permettant de ménager un évidement entre le support d’aile 4 et la plateforme 11 , relativement à un axe vertical Z. Complémentairement, le support de joint de capot 1 comporte un système d’amorce de rupture 15 configuré pour rompre le dispositif de fixation 12 si un effort appliqué sur le support de joint de capot 1 dépasse une intensité nominale de rupture prédéterminée. [102] In summary, the invention relates to a hood seal support 1 having a platform 11 for fixing a hood seal 2, the support comprising a fixing device 12 on a wing support 4 of a motor vehicle 7 making it possible to provide a recess between the wing support 4 and the platform 11, relative to a vertical axis Z. Additionally, the hood joint support 1 comprises a break initiator system 15 configured to break the fixing device 12 if a force applied to the hood seal support 1 exceeds a predetermined nominal breaking intensity.

Notamment, les différentes caractéristiques, formes, variantes et modes de réalisation de l’invention peuvent être associées les unes avec les autres selon diverses combinaisons dans la mesure où elles ne sont pas incompatibles ou exclusives les unes des autres. En particulier toutes les variantes et modes de réalisation décrits précédemment sont combinables entre eux. [103] Of course, the invention is not limited to the examples which have just been described and numerous adjustments can be made to these examples without departing from the scope of the invention. In particular, the different characteristics, shapes, variants and embodiments of the invention can be associated with each other in various combinations to the extent that they are not incompatible or exclusive of each other.
