5 Domaine technique de l’invention 5 Technical field of the invention
La présente invention revendique la priorité de la demande française 2103798 déposée le 13.04.2021 dont le contenu (texte, dessins et revendications) est ici incorporé par référence. L’invention concerne les blocs optiques qui équipent certains véhicules terrestres et sur lesquels 0 s’appuient les pare-chocs de tels véhicules. The present invention claims the priority of French application 2103798 filed on 04.13.2021, the content of which (text, drawings and claims) is incorporated herein by reference. The invention relates to the optical units which equip certain land vehicles and on which the bumpers of such vehicles rest.
Etat de la technique State of the art
Certains véhicules terrestres, souvent de type automobile, comprennent, généralement dans une partie avant, un pare-chocs ayant une partie 5 supérieure s’appuyant sur la glace d’au moins un bloc optique (et généralement de deux blocs optiques droit et gauche). Certain land vehicles, often of the automobile type, generally comprise, in a front part, a bumper having an upper part resting on the glass of at least one optical unit (and generally of two right and left optical units) .
A cet effet, la glace du (de chaque) bloc optique comprend une partie principale, par laquelle sortent des photons participant à au moins une fonction photométrique, et comprenant dans une sous-partie inférieure au moins une 0 nervure (ou protubérance) dite « interne » et une nervure (ou protubérance) dite « externe » comportant respectivement des surfaces d’appui sur lesquelles s’appuie la partie supérieure du pare-chocs. To this end, the crystal of (each) optical unit comprises a main part, through which photons participating in at least one photometric function emerge, and comprising in a lower sub-part at least one rib (or protuberance) called " internal" and a so-called "external" rib (or protuberance) respectively comprising bearing surfaces on which the upper part of the bumper rests.
On entend ici par « nervure externe » une nervure qui est située à proximité d’un côté latéral (ou longitudinal) d’un véhicule, et par « nervure interne » une 5 nervure qui est distante de cette nervure externe et située plus près de l’axe médian du véhicule que cette dernière. Here, the term "outer rib" means a rib which is located close to a lateral (or longitudinal) side of a vehicle, and the term "inner rib" means a rib which is distant from this outer rib and located closer to the center line of the vehicle than the latter.
Dans certains blocs optiques, la partie principale de la glace est définie dans un moule par une première injection d’une première matière plastique ayant généralement une couleur dite « cristal », et elle est prolongée latéralement, 0 au moins sur un côté latéral externe, par une partie latérale externe définie dans ce même moule par une seconde injection d’une seconde matière plastique ayant généralement une couleur noire afin de masquer des parties techniques (et donc inesthétiques). La partie latérale externe est donc surmoulée sur un bord d’interface de la partie principale. Un tel surmoulage assure une solidarisation de qualité et une parfaite étanchéité lorsque l’interface (partie principale/partie latérale externe) ne subit pas une contrainte relativement importante, comme lorsque la nervure externe est relativement éloignée de l’interface. Mais, si la nervure externe était définie à proximité immédiate de l’interface, cette interface subirait une contrainte de cisaillement trop importante qui pourrait entraîner sa fissuration et donc pourrait induire une diminution notable de la qualité de la solidarisation et de la qualité de l’étanchéité. Or, cet empêchement peut s’avérer pénalisant dans certaines situations. C’est notamment le cas lorsque l’on veut installer entre les nervures interne et externe un équipement ayant une extension transversale plus importante que l’extension transversale maximale possible entre ces nervures interne et externe du fait de l’empêchement précité. Un tel équipement peut, par exemple, être un autre bloc optique assurant une fonction de feu de jour (ou DRL (« Daytime running Light (ou Lamp) » - signalisation lumineuse allumée automatiquement lorsque le véhicule est mis en fonctionnement pendant le jour)). In certain optical units, the main part of the crystal is defined in a mold by a first injection of a first plastic material generally having a so-called "crystal" color, and it is extended laterally, 0 at least on an external lateral side, by an external lateral part defined in this same mold by a second injection of a second plastic material generally having a black color in order to mask technical (and therefore unsightly) parts. The outer side part is therefore molded over an interface edge of the main part. Such overmolding ensures high-quality fastening and perfect sealing when the interface (main part/external lateral part) is not subjected to a relatively high stress, such as when the external rib is relatively far from the interface. But, if the external rib were defined in the immediate vicinity of the interface, this interface would undergo too great a shearing stress which could lead to its cracking and therefore could induce a notable reduction in the quality of the connection and the quality of the sealing. However, this impediment can prove to be penalizing in certain situations. This is particularly the case when it is desired to install between the internal and external ribs equipment having a greater transverse extension than the maximum possible transverse extension between these internal and external ribs due to the aforementioned impediment. Such equipment may, for example, be another optical unit providing a daytime running light function (or DRL ("Daytime running Light (or Lamp)" - light signaling automatically switched on when the vehicle is put into operation during the day) .
L’invention a donc notamment pour but d’améliorer la situation. Présentation de l’invention The aim of the invention is therefore in particular to improve the situation. Presentation of the invention
Elle propose notamment à cet effet un bloc optique propre à équiper un véhicule terrestre comprenant un pare-chocs, et comprenant une glace ayant une partie principale et une partie latérale externe définies respectivement par des première et seconde injections de première et seconde matières plastiques, cette partie principale comprenant une nervure comportant une surface d’appui sur laquelle est destinée à s’appuyer une partie supérieure du pare-chocs. It proposes in particular for this purpose an optical unit suitable for equipping a land vehicle comprising a bumper, and comprising a glass having a main part and an external lateral part defined respectively by first and second injections of first and second plastic materials, this main part comprising a rib comprising a bearing surface on which an upper part of the bumper is intended to rest.
Ce bloc optique se caractérise par le fait que la nervure est située juste avant une interface avec la partie latérale externe et comprend un logement concave défini lors de la première injection en étant ouvert du côté de cette dernière puis rempli au moins partiellement de la seconde matière plastique lors de la seconde injection. This optical unit is characterized in that the rib is located just before an interface with the external lateral part and comprises a concave housing defined during the first injection by being open on the side of the latter and then filled at least partially with the second material plastic during the second injection.
Ainsi, la nervure externe fait partie intégrante de l’interface entre la partie principale et la partie latérale externe, et donc la partie supérieure du pare- chocs peut s’appuyer très latéralement sur sa surface d’appui sans que cela n’induise de fissuration d’interface. Thus, the outer rib is an integral part of the interface between the part main part and the outer side part, and therefore the upper part of the bumper can rest very laterally on its bearing surface without this causing interface cracking.
Le bloc optique selon l’invention peut comporter d’autres caractéristiques qui peuvent être prises séparément ou en combinaison, et notamment : The optical block according to the invention may comprise other characteristics which may be taken separately or in combination, and in particular:
- la partie principale de sa glace peut comprendre une sous-partie supérieure par laquelle sortent des photons participant à au moins une fonction photométrique, et une sous-partie inférieure prolongeant vers le bas cette sous-partie supérieure, destinée à être masquée par le pare-chocs et dans laquelle est définie la nervure ; - the main part of its crystal may include an upper sub-part through which photons participating in at least one photometric function emerge, and a lower sub-part extending this upper sub-part downwards, intended to be masked by the visor -shocks and in which the rib is defined;
- en présence de la première option, la sous-partie inférieure de la partie principale de la glace peut être définie en retrait d’un bord inférieur de la sous- partie supérieure qui définit une casquette au-dessus de la surface d’appui de la nervure et délimite avec cette surface d’appui un logement destiné à loger une sous-partie du pare-chocs ; - in the presence of the first option, the lower sub-part of the main part of the glass can be set back from a lower edge of the upper sub-part which defines a cap above the bearing surface of the rib and delimits with this bearing surface a housing intended to house a sub-part of the bumper;
- en présence de la dernière sous-option, la casquette peut être creuse et peut comprendre une face interne délimitant un logement interne ouvert vers l’intérieur du bloc optique et comprenant une partie inférieure recouverte de la seconde matière plastique lors de la seconde injection dans une partie au moins d’une zone située au-dessus de la surface d’appui de la nervure ; - in the presence of the last sub-option, the cap can be hollow and can comprise an internal face delimiting an internal housing open towards the interior of the optical unit and comprising a lower part covered with the second plastic material during the second injection into at least part of a zone located above the bearing surface of the rib;
- la nervure peut avoir une forme générale en L inversé ; - The rib may have a general inverted L shape;
- la partie principale de sa glace peut comprendre une autre nervure distante de la nervure (« bicouches ») et comportant une surface d’appui sur laquelle est destinée à s’appuyer la partie supérieure du pare-chocs ; - il peut assurer au moins une fonction photométrique d’éclairage choisie parmi une fonction photométrique de feu de route et une fonction photométrique de feu de croisement. - the main part of its glass may include another rib distant from the rib (“double layers”) and comprising a support surface on which the upper part of the bumper is intended to rest; - it can perform at least one photometric lighting function chosen from among a photometric main beam function and a photometric dipped beam function.
L’invention propose également un véhicule terrestre, éventuellement de type automobile, et comprenant un pare-chocs et au moins un bloc optique du type de celui présenté ci-avant et sur lequel s’appuie le pare-chocs. The invention also proposes a land vehicle, possibly of the automobile type, and comprising a bumper and at least one optical unit of the type of that presented above and on which the bumper rests.
Par exemple, ce véhicule peut comprendre une partie avant comportant le pare-chocs et chaque bloc optique. Brève description des figures For example, this vehicle can comprise a front part comprising the bumper and each optical unit. Brief description of figures

Description détaillée de l’invention Detailed description of the invention
L’invention a notamment pour but de proposer un bloc optique BO destiné à équiper un véhicule terrestre et comprenant une glace GL sur laquelle est destiné à s’appuyer un pare-chocs PC, et permettant par exemple le placement d’un autre équipement BO’ à encombrement transversal important devant elle (GL). The aim of the invention is in particular to propose an optical unit BO intended to equip a land vehicle and comprising a glass GL on which a bumper PC is intended to rest, and allowing for example the placement of another equipment BO 'with significant transverse space in front of it (GL).
Dans ce qui suit, on considère, à titre d’exemple non limitatif, que le véhicule terrestre est un véhicule automobile, comme par exemple une voiture. Mais l’invention n’est pas limitée à ce type de véhicule terrestre. Elle concerne en effet tout véhicule terrestre comprenant un pare-chocs devant s’appuyer sur au moins un bloc optique. In what follows, it is considered, by way of non-limiting example, that the land vehicle is a motor vehicle, such as a car for example. But the invention is not limited to this type of land vehicle. It relates in fact to any land vehicle comprising a bumper that must rest on at least one optical unit.
Par ailleurs, on considère dans ce qui suit, à titre d’exemple non limitatif, que le pare-chocs PC et chaque bloc optique BO sont destinés à faire partie de la partie avant d’un véhicule terrestre. Mais cela n’est pas obligatoire. En effet, ils pourraient être destinés à faire partie de la partie arrière d’un véhicule terrestre. Dans ce qui précède et ce qui suit la notion « d’avant » est définie par rapport à l’extrémité avant du véhicule, et la notion « d’arrière » est définie par rapport à l’extrémité arrière du véhicule (opposée à l’extrémité avant). Par conséquent, la partie (ou face) avant d’un élément est orientée vers l’extrémité avant du véhicule, tandis que la partie (ou face) arrière de cet élément est orientée vers l’extrémité arrière du véhicule. De plus, on considère dans ce qui suit, à titre d’exemple non limitatif, que chaque bloc optique BO est un projecteur (ou phare) assurant au moins une fonction d’éclairage, comme par exemple une fonction de feu de route ou une fonction de feu de croisement. Mais l’invention n’est pas limitée à ce type de bloc optique. Compte tenu de la dernière hypothèse, le pare-chocs PC est ici destiné à s’appuyer sur deux blocs optiques BO droit et gauche installés respectivement à proximité des côtés latéraux (ou longitudinaux) droit et gauche du véhicule qui comportent les portières latérales. Furthermore, it is considered in what follows, by way of non-limiting example, that the bumper PC and each optical unit BO are intended to form part of the front part of a land vehicle. But this is not mandatory. Indeed, they could be intended to form part of the rear part of a land vehicle. In what precedes and what follows, the notion of "front" is defined in relation to the front end of the vehicle, and the notion of "rear" is defined in relation to the rear end of the vehicle (as opposed to the front end). Consequently, the front part (or face) of an element is oriented towards the front end of the vehicle, while the rear part (or face) of this element is oriented towards the rear end of the vehicle. In addition, it is considered in what follows, by way of non-limiting example, that each optical unit BO is a projector (or headlight) ensuring at least one lighting function, such as for example a high beam function or a low beam function. But the invention is not limited to this type of optical block. Given the last hypothesis, the bumper PC is here intended to rest on two right and left optical units BO installed respectively close to the right and left lateral (or longitudinal) sides of the vehicle which comprise the side doors.
Sur les figures 1 à 5, la direction X est la direction longitudinale du véhicule, laquelle est parallèle aux côtés latéraux comportant les portières latérales, la direction Y est la direction transversale du véhicule, laquelle est perpendiculaire aux côtés latéraux et à la direction longitudinale X, et la direction Z est la direction verticale du véhicule, laquelle est perpendiculaire aux directions longitudinale X et transversale Y. On a schématiquement illustré sur la figure 1 un exemple de réalisation d’un bloc optique BO selon l’invention, avant qu’il n’équipe un véhicule (terrestre) (ici sa partie avant) et qu’un pare-chocs PC ne vienne s’appuyer sur lui. Comme illustré partiellement, un bloc optique BO, selon l’invention, comprend une glace GL solidarisée fixement à un boîtier (non représenté). Cette glace GL comprend une partie principale PP et au moins une partie latérale externeIn FIGS. 1 to 5, the direction X is the longitudinal direction of the vehicle, which is parallel to the lateral sides comprising the side doors, the direction Y is the transverse direction of the vehicle, which is perpendicular to the lateral sides and to the longitudinal direction X , and the direction Z is the vertical direction of the vehicle, which is perpendicular to the longitudinal X and transverse Y directions. FIG. 1 schematically illustrates an embodiment of an optical unit BO according to the invention, before it does not equip a (land) vehicle (here its front part) and that a PC bumper comes to lean on it. As partially illustrated, an optical unit BO, according to the invention, comprises a lens GL fixedly secured to a housing (not shown). This GL glass comprises a main part PP and at least one external side part
PLE définies respectivement par des première et seconde injections de première M1 et seconde M2 matières plastiques dans un moule comprenant au moins une partie pouvant être déplacée. La partie principale PP de la glace GL est la partie du bloc optique BO par laquelle sortent des photons qui participent à chaque fonction photométrique assurée par ce dernier (BO). Elle est donc réalisée dans une première matière plastique M1 ayant généralement une couleur dite « cristal ». La partie latérale externe PLE prolonge la partie principale PP sur un côté latéral (ou longitudinal) du véhicule. Elle a donc un bord qui est partiellement surmoulé lors de la seconde injection sur un bord de la partie principale PP, au niveau d’une interface de liaison (ou solidarisation). Etant destinée à masquer des parties techniques (et donc inesthétiques) du bloc optique BO (notamment internes), elle est réalisée dans une seconde matière plastique M2 ayant généralement une couleur noire. PLE defined respectively by first and second injections of first M1 and second M2 plastic materials into a mold comprising at least one part that can be moved. The main part PP of the lens GL is the part of the optical block BO through which photons emerge which participate in each photometric function ensured by the latter (BO). It is therefore made of a first plastic material M1 generally having a so-called “crystal” color. The outer side part PLE extends the main part PP on a lateral (or longitudinal) side of the vehicle. It therefore has an edge which is partially overmoulded during the second injection on an edge of the main part PP, at the level of a connection (or joining) interface. Being intended to mask technical (and therefore unsightly) parts of the optical unit BO (particularly internal ones), it is made of a second plastic material M2 generally having a black color.
On notera que les première M1 et seconde M2 matières plastiques peuvent, par exemple, être du polycarbonate (ou PC) mais ayant des couleurs différentes. La partie principale PP comprend une nervure N1 comportant une surface d’appui SA1 sur laquelle est destinée à s’appuyer une partie supérieure d’un pare-chocs PC, comme illustré très schématiquement sur la figure 4. It will be noted that the first M1 and second M2 plastic materials can, for example, be polycarbonate (or PC) but having different colors. The main part PP comprises a rib N1 comprising a support surface SA1 on which an upper part of a bumper PC is intended to rest, as illustrated very schematically in FIG. 4.
Cette nervure N1 est située juste avant l’interface avec la partie latérale externe PLE, ce qui fait qu’elle est appelée nervure externe ci-après. De plus, cette nervure externe N1 comprend un logement concave LC qui est défini lors de la première injection en étant ouvert du côté de cette dernière (PLE) puis qui est rempli au moins partiellement de la seconde matière plastique M2 lors de la seconde injection. De préférence, le logement concave LC est rempli intégralement de la seconde matière plastique M2. En d’autres termes, la nervure externe N1 comprend une première couche « principale » réalisée dans la première matière plastique M1 , et une seconde couche « complémentaire » surmoulée sur la première couche au moins dans le logement concave LC et réalisée dans la seconde matière plastique M2, comme illustré sur les figures 3 et 4. Le positionnement de la première couche principale de la nervure externe N1 juste avant l’interface permet de lui adjoindre la seconde couche complémentaire par surmoulage et donc qu’elle fasse partie intégrante de l’interface, ce qui permet à la partie supérieure du pare-chocs PC de s’appuyer très latéralement (suivant la direction transversale Y) sur sa surface d’appui SA1 réalisée par la seule première couche principale et non par la seconde couche complémentaire, et par conséquent sans risque de fissuration d’interface. This rib N1 is located just before the interface with the external lateral part PLE, which means that it is called external rib hereafter. In addition, this outer rib N1 comprises a concave housing LC which is defined during the first injection by being open on the side of the latter (PLE) then which is filled at least partially with the second plastic material M2 during the second injection. Preferably, the concave housing LC is completely filled with the second plastic material M2. In other words, the outer rib N1 comprises a first "main" layer made of the first plastic material M1, and a second "complementary" layer overmolded on the first layer at least in the concave housing LC and made of the second material plastic M2, as illustrated in FIGS. 3 and 4. The positioning of the first main layer of the external rib N1 just before the interface makes it possible to add the second additional layer to it by overmolding and therefore to make it an integral part of the interface, which allows the upper part of the PC bumper to lean very laterally (in the transverse direction Y) on its bearing surface SA1 produced by the first main layer alone and not by the second complementary layer, and consequently without risk of interface cracking.
De plus, cet agencement de la nervure externe N1 permet d’augmenter notablement sa rigidité, ce qui permet notamment, en cas de besoin, de réduire son extension suivant la direction transversale Y. Un tel besoin peut notamment survenir lorsque, comme illustré non limitativement sur les figures 1 et 5, la partie principale PP comprend une autre nervure N2, ci-après appelée nervure interne du fait qu’elle est distante de la nervure externe N1 , et comportant une surface d’appui SA2 sur laquelle est aussi destinée à s’appuyer la partie supérieure du pare-chocs PC, et que l’on veut installer entre ces nervures interne N2 et externe N1 un équipement BO’ ayant une extension transversale importante (voir figure 5). On comprendra en effet que l’on peut désormais disposer d’un grand espacement transversal entre les nervures interne N2 et externe N1 , adapté à un large équipement BO’. In addition, this arrangement of the outer rib N1 makes it possible to significantly increase its rigidity, which makes it possible in particular, if necessary, to reduce its extension in the transverse direction Y. Such a need can arise in particular when, as illustrated without limitation in Figures 1 and 5, the main part PP comprises another rib N2, hereinafter called internal rib because it is remote from the external rib N1, and comprising a bearing surface SA2 on which is also intended to lean the upper part of the bumper PC, and that one wants to install between these internal ribs N2 and external N1 equipment BO 'having a large transverse extension (see Figure 5). It will indeed be understood that it is now possible to have a large transverse spacing between the internal N2 and external N1 ribs, suitable for a large equipment BO '.
Dans l’exemple illustré non limitativement sur la figure 5, l’équipement BO’ est un autre bloc optique assurant une fonction de feu de jour (ou DRL (Daytime running Light (ou Lamp)) à trois bandes. Mais d’autres types d’équipement pourraient être installés, qu’il s’agisse ou non d’un bloc optique. On notera que la réalisation « bicouches » de la nervure externe N1 nécessite l’utilisation d’un moule de bi-injection à démoulage latéral permettant la réalisation du logement concave LC orienté vers l’extérieur. En effet, le côté intérieur de la nervure externe N1 (opposé au logement concave LC) démoule naturellement, tandis que le côté extérieur de la nervure externe N1 (logement concave LC), en contre dépouille, est démoulée par un mouvement latéral d’une partie du moule adaptée à cet effet. In the example illustrated without limitation in FIG. 5, the equipment BO′ is another optical unit ensuring a daytime running light (or DRL (Daytime running Light (or Lamp)) function with three bands. But other types equipment could be installed, whether or not it is an optical block. It should be noted that the "two-layer" production of the external rib N1 requires the use of a bi-injection mold with lateral release allowing the realization of the concave housing LC oriented towards the outside. Indeed, the inner side of the external rib N1 (opposite to the concave housing LC) demolds naturally, while the external side of the external rib N1 (concave housing LC), in undercut, is unmolded by a lateral movement of a part of the mold adapted for this purpose.
Par exemple, et comme illustré non limitativement sur les figures 1 et 5, la partie principale PP peut comprendre une sous-partie supérieure SPS et une sous- partie inférieure SPI prolongeant vers le bas cette sous-partie supérieure SPS. C’est par cette sous-partie supérieure SPS que sortent les photons participant à chaque fonction photométrique du bloc optique BO. Elle est donc visible de l’extérieur du véhicule. La nervure externe N1 est définie dans la sous-partie inférieure SPI qui est destinée à être masquée par le pare-chocs PC et partiellement par l’éventuel équipement BO’. For example, and as illustrated without limitation in FIGS. 1 and 5, the main part PP can comprise an upper sub-part SPS and a lower sub-part SPI extending this upper sub-part SPS downwards. It is via this upper sub-part SPS that the photons taking part in each photometric function of the optical block BO emerge. It is therefore visible from outside the vehicle. The external rib N1 is defined in the lower sub-part SPI which is intended to be masked by the bumper PC and partially by any equipment BO'.
On notera, comme illustré non limitativement sur les figures 1 à 5, que la sous- partie inférieure SPI peut être définie en retrait du bord inférieur Bl de la sous- partie supérieure SPS. Ce bord Bl définit alors une casquette au-dessus de la surface d’appui SA1 de la nervure externe N1 et délimite avec cette surface d’appui SA1 un logement LP qui est destiné à loger une sous-partie de la partie supérieure du pare-chocs PC (voir figure 4). Cette casquette permet de garantir la constance de la ligne d’accostage visible et commune entre le pare-chocs PC et la partie visible de la glace GL de chaque bloc optique BO. On notera également, comme illustré non limitativement sur les figures 3 et 4, que la casquette Bl peut être creuse et peut comprendre une face interne Fl qui délimite un logement interne Ll ouvert vers l’intérieur du bloc optique BO. Cette face interne Fl comprend une partie inférieure PIF qui est recouverte de la seconde matière plastique M2 lors de la seconde injection dans une partie au moins d’une zone qui est située au-dessus de la surface d’appui SA1 de la nervure externe N1 . Cela permet de réduire encore plus le risque de fissuration de l’interface puisque la seconde matière plastique M2 surmoulée dans le logement concave LC de la nervure externe N1 se prolonge continûment au- dessus de cette dernière (N1) jusque sur la face interne Fl de la casquette Bl. On notera également, comme illustré non limitativement sur les figures 1 , 2 etIt will be noted, as illustrated without limitation in FIGS. 1 to 5, that the lower sub-part SPI can be set back from the lower edge B1 of the upper sub-part SPS. This edge Bl then defines a cap above the bearing surface SA1 of the external rib N1 and delimits with this bearing surface SA1 a housing LP which is intended to house a sub-part of the upper part of the visor. PC shocks (see Figure 4). This cap makes it possible to guarantee the constancy of the visible and common docking line between the bumper PC and the visible part of the glass GL of each optical unit BO. It will also be noted, as illustrated without limitation in FIGS. 3 and 4, that the cap B1 may be hollow and may comprise an internal face F1 which delimits an internal housing L1 open towards the interior of the optical block BO. This internal face Fl comprises a lower part PIF which is covered with the second plastic material M2 during the second injection in at least part of a zone which is located above the bearing surface SA1 of the external rib N1 . This makes it possible to further reduce the risk of cracking of the interface since the second plastic material M2 molded into the concave housing LC of the external rib N1 extends continuously above the latter (N1) as far as the internal face F1 of the cap Bl. Note also, as illustrated without limitation in Figures 1, 2 and
5, que la nervure externe N1 peut avoir une forme générale en L inversé. Cela permet d’améliorer sa rigidité tout en offrant une surface d’appui SA1 relativement importante. Mais d’autres formes peuvent être envisagées. 5, that the outer rib N1 may have the general shape of an inverted L. This improves its rigidity while providing a relatively large SA1 support surface. But other forms can be considered.
