L'invention peut notamment s'appliquer à un hayon de véhicule.The invention may especially apply to a vehicle tailgate.
Lorsqu'un hayon de véhicule dépourvu de moyens déformables reçoit un choc arrière, même à vitesse réduite, il est souvent nécessaire de le remplacer dans sa totalité. De plus, le reste de la structure est généralement lui aussi touché ainsi que les charnières servant à fixer le hayon sur la caisse. Ainsi les réparations sont très coûteuses.When a vehicle tailgate devoid of deformable means receives a rear impact, even at reduced speed, it is often necessary to replace it in its entirety. In addition, the rest of the structure is usually also affected and the hinges used to fix the tailgate on the body. So repairs are very expensive.
On connaît déjà dans l'état de la technique des hayons possédant des moyens déformables, par exemple des boucliers arrière. La demande de brevet FR2750365 décrit un hayon de véhicule équipé d'un bouclier de pare-chocs, ce dernier étant destiné à protéger la carrosserie du véhicule lors d'un choc et à dissiper l'énergie de ce choc.Already known in the state of the art hayons having deformable means, for example rear shields. The patent application FR2750365 describes a vehicle tailgate equipped with a bumper shield, the latter being intended to protect the body of the vehicle during an impact and to dissipate the energy of the shock.
Toutefois ce type d'agencement n'est pas suffisant ; en cas de chocs, les dégâts constatés sur le véhicule restent lourds et leur réparation coûteuse.However this type of arrangement is not enough; in case of shocks, the damage observed on the vehicle remains heavy and their repair costly.
Un but de la présente invention est de pallier tout ou partie des inconvénients de l'art antérieur relevés ci-dessus.

Sur ces figures, des références identiques désignent des organes ou ensembles d'organes identiques ou analogues.In these figures, identical references denote identical or similar organs or sets of members.
Sur la figure 1 est représenté la partie arrière d'un véhicule automobile équipé d'un hayon.In Figure 1 is shown the rear portion of a motor vehicle equipped with a tailgate.
L'ouvrant arrière comprend de façon classique :The rear opening conventionally comprises:
- une lunette ou vitre arrière 7, montée dans une ouverture située dans la partie supérieure de l'ouvrant, - une partie inférieure opaque 8 permettant de fermer un coffre arrière 9 en se rabattant sur un bouclier arrière 10.- A rear window or window 7, mounted in an opening in the upper part of the opening, an opaque lower part 8 making it possible to close a rear trunk 9 by folding on a rear bumper 10.
De façon connue, la partie inférieure 8 du hayon est constituée par un panneau intérieur 1 porteur, placé côté intérieur du véhicule, et par un panneau d'habillage extérieur 2 qui est une peau extérieure de carrosserie fixée sur le panneau porteur 1 . Les deux panneaux 1 , 2 sont en matériau métallique.In known manner, the lower part 8 of the tailgate is constituted by a carrier inner panel 1, placed on the inside of the vehicle, and by an outer cladding panel 2 which is an outer body skin fixed on the carrier panel 1. The two panels 1, 2 are made of metallic material.
Le hayon du véhicule, tel que le montre la figure 1 , est sensiblement aligné avec le bouclier arrière 10 du véhicule.The tailgate of the vehicle, as shown in Figure 1, is substantially aligned with the rear bumper 10 of the vehicle.
Sur la figure 1 , deux parties A, B du hayon sont mises en évidence, chacune correspondant à un mode de réalisation de l'invention.In Figure 1, two parts A, B of the tailgate are highlighted, each corresponding to an embodiment of the invention.
A partir de ce point chacun des modes de réalisation va être décrit séparément.From this point each of the embodiments will be described separately.
En ce qui concerne le premier mode de réalisation (partie A), la figure 2 met en évidence un panneau intérieur 1 et un panneau extérieur 2 réalisés en tôle emboutie, plies et soudés à l'un sur l'autre de façon traditionnelle.With regard to the first embodiment (part A), Figure 2 shows an inner panel 1 and an outer panel 2 made of stamped sheet metal, folded and welded to one another in the traditional manner.
Le hayon porte sensiblement au niveau de son bord transversal inférieur, un enjoliveur plastique 6 fixé sur le panneau extérieur 2 du hayon.The tailgate substantially at its lower transverse edge, a plastic trim 6 attached to the outer panel 2 of the tailgate.
Cet enjoliveur 6 recouvre partiellement le panneau extérieur 2 dans sa partie basse. Il peut notamment jouer un rôle esthétique car il est presque affleurant avec le bouclier 10 et garanti ainsi une continuité de surface entre le bouclier 10 et le hayon. Selon l'invention, l'enjoliveur 6 est fixé avec le panneau extérieur 2 par tout moyen approprié tel que des vis de façon à définir un volume creux 11 . L'enjoliveur 6 réalisé en une seule pièce comprend une paroi avant 12, bordée successivement dans sa partie inférieure et dans sa partie supérieure par deux parois 14, 13 par lesquelles l'enjoliveur 6 est fixé au panneau extérieur 2.This hubcap 6 partially covers the outer panel 2 in its lower part. It can notably play an aesthetic role because it is almost flush with the shield 10 and thus guarantees a surface continuity between the shield 10 and the tailgate. According to the invention, the hubcap 6 is fixed with the outer panel 2 by any appropriate means such as screws so as to define a hollow volume 11. The hubcap 6 made in one piece comprises a front wall 12, successively lined in its lower part and in its upper part by two walls 14, 13 by which the hubcap 6 is fixed to the outer panel 2.
Plus précisément, la paroi 14 située inférieurement présente, à l'opposé de la paroi avant 12, un bord arrière fixé au panneau extérieur 2. Cette paroi 14 est voisine du bouclier 10.More specifically, the wall 14 located below has, opposite the front wall 12, a rear edge fixed to the outer panel 2. This wall 14 is close to the shield 10.
La paroi 13 située supérieurement permet de fermer le volume creux 11 présent entre le panneau extérieur 2 et l'enjoliveur 6 et d'assurer l'unité esthétique du hayon arrière.The wall 13 located above allows to close the hollow volume 11 present between the outer panel 2 and the hubcap 6 and to ensure the aesthetic unity of the tailgate.
Selon l'invention, la paroi 14 comprend des moyens frangibles 3 aptes à absorber, lors de leur rupture, au moins une partie de l'énergie d'un choc subi par le hayon.According to the invention, the wall 14 comprises frangible means 3 capable of absorbing, upon their rupture, at least a portion of the energy of an impact sustained by the tailgate.
Ainsi, la paroi 14 est déformable : elle comporte en effet au moins une zone de rupture 4 prédéterminée formant les moyens frangibles précités.Thus, the wall 14 is deformable: it comprises in fact at least one predetermined breaking zone 4 forming the frangible means mentioned above.
En pratique, la paroi 14 de l'enjoliveur 6 comporte au moins deux parties gigognes 5A, 5B, raccordées par une ligne de moindre épaisseur 4. Selon le mode de réalisation représenté sur la figure 2, quatre parties gigognes successives 5A, 5B, 5C, 5D sont prévues, reliées deux à deux par une ligne de moindre épaisseur 4.In practice, the wall 14 of the trim 6 comprises at least two nesting portions 5A, 5B, connected by a line of smaller thickness 4. According to the embodiment shown in Figure 2, four successive nesting portions 5A, 5B, 5C , 5D are provided, connected in pairs by a line of lesser thickness 4.
Ainsi, un choc arrière subi par le hayon provoque le recul de la paroi avant 12, entraînant la rupture successive des lignes de moindre épaisseur 4, et l'empilement des parties gigognes 5A, 5B, 5C, 5D, comme le montre la figure 3. Ainsi pour un choc à basse vitesse (maximum 10 km/h), le hayon est guidé dans son recul et se déforme de manière prédéterminée. Ainsi seul l'enjoliveur 6 plastique doit être changé, le reste du hayon restant intact. L'intérêt de l'invention est clairement mis en évidence, les coûts de réparation sont nettement réduits par rapport à ceux supportés par un véhicule non équipé du hayon de l'invention.Thus, a rear impact sustained by the tailgate causes the recoil of the front wall 12, resulting in the successive breaking of the lines of smaller thickness 4, and the stacking of the nesting portions 5A, 5B, 5C, 5D, as shown in FIG. . Thus for a shock at low speed (maximum 10 km / h), the tailgate is guided in its recoil and is deformed in a predetermined manner. Thus only the plastic hubcap 6 must be changed, the rest of the tailgate remaining intact. The advantage of the invention is clearly demonstrated, the repair costs are significantly reduced compared to those supported by a vehicle not equipped with the tailgate of the invention.
De plus, le véhicule équipé de l'ouvrant de l'invention sera classé comme « peu coûteux » à réparer ce qui permettra au conducteur d'obtenir un rabais de sa police d'assurance.In addition, the vehicle equipped with the opening of the invention will be classified as "inexpensive" to repair which will allow the driver to obtain a discount of his insurance policy.
Bien sûr, les moyens frangibles peuvent être composés d'une seule zone de rupture 4 ; dans ce cas, lors d'un choc, la ligne de moindre épaisseur 4 se rompt et entraîne l'affaissement des zones situées de part et d'autre de cette ligne 4.Of course, the frangible means may be composed of a single rupture zone 4; in this case, during an impact, the line of smaller thickness 4 breaks and causes the collapse of the zones located on either side of this line 4.
Voyons maintenant le second mode de réalisation de cette invention tel que présenté à la figure 4.Let us now see the second embodiment of this invention as shown in Figure 4.
Selon ce mode de réalisation, la panneau intérieur 1 et le panneau extérieur 2 sont en matériau composite. Ils sont assemblés par des moyens appropriés. Le panneau intérieur 1 réalisé en une seule pièce possède une forme de « L » :According to this embodiment, the inner panel 1 and the outer panel 2 are made of composite material. They are assembled by appropriate means. The inner panel 1 made in one piece has an "L" shape:
- une première partie 15 est sensiblement parallèle au panneau extérieur 2,a first part 15 is substantially parallel to the outer panel 2,
- une seconde partie 16 est sensiblement perpendiculaire à la première partie 15 mentionnée ci-dessus et donc au panneau extérieur 2.a second part 16 is substantially perpendicular to the first part 15 mentioned above and therefore to the outer panel 2.
La seconde partie 16 du panneau intérieur 1 comprend les moyens frangibles 3 identiques à ceux décrit précédemment. Plus particulièrement les moyens frangibles 3 sont adjacents au panneau extérieur 2. En cas de choc arrière, les moyens frangibles 3 réagissent comme ceux décrits précédemment. Alors lors d'un choc, le hayon, conforme à ce mode de réalisation, doit être intégralement changé mais le reste de la structure n'est pas impacté par le choc.The second portion 16 of the inner panel 1 comprises the frangible means 3 identical to those described above. More particularly, the frangible means 3 are adjacent to the outer panel 2. In case of rear impact, the frangible means 3 react as those described above. So during a shock, the tailgate, according to this embodiment, must be completely changed but the rest of the structure is not impacted by the shock.
Un troisième mode de réalisation, non représenté, peut être envisagé. Selon ce mode de réalisation, le panneau intérieur 1 et le panneau extérieur 2 sont sensiblement de forme plane et sont sensiblement placés de façon parallèle. Un panneau complémentaire situé inférieurement permet de relier le panneau intérieur 1 au panneau extérieur 2, ce panneau est voisin du bouclier 10. Selon ce mode, les moyens frangibles 3 appartiennent au panneau complémentaire.A third embodiment, not shown, can be envisaged. According to this embodiment, the inner panel 1 and the outer panel 2 are substantially planar in shape and are substantially placed in parallel fashion. A lower complementary panel allows to connect the inner panel 1 to the outer panel 2, this panel is close to the shield 10. In this mode, the frangible means 3 belong to the complementary panel.
Bien sûr, des variantes des hayons réalisés selon le second et le troisième mode de réalisation peuvent être envisagés. Dans ces cas :Of course, variants of tailgates made according to the second and the third embodiment can be envisaged. In such cases :
- les moyens frangibles 3 peuvent appartenir au panneau extérieur 1 et/ou,the frangible means 3 can belong to the outer panel 1 and / or,
- le panneau extérieur 2 peut être en tôle tandis que le panneau intérieur 1 est en composite, les deux panneaux étant reliés par des moyens appropriés.- The outer panel 2 may be sheet metal while the inner panel 1 is composite, the two panels being connected by appropriate means.
Les hayons réalisés selon ces différents modes de réalisation présentent un intérêt particulier pour les silhouettes de véhicule dont le hayon est aligné avec le bouclier 10.The hatches made according to these different embodiments are of particular interest for vehicle silhouettes whose tailgate is aligned with the shield 10.
L'invention peut s'appliquer aux hayons arrière réalisés en deux parties ; plus particulièrement, l'invention peut s'appliquer à la partie formant l'abattant.The invention can be applied to tailgates made in two parts; more particularly, the invention can be applied to the portion forming the flap.
Bien sûr, l'invention peut également s'appliquer aux autres ouvrants du véhicule, par exemple aux portes latérales battantes ou coulissantes. Of course, the invention can also be applied to other openings of the vehicle, for example to swinging or sliding side doors.
