- the present invention relates to the field of security devices, in particular the production of burglar-resistant containers of the box or chamber type, and relates to a composite armored wall.
- document DE-A-3 808 417 describes a composite armored wall comprising in particular an outer plate having a high resistance to the conventional oxyacetylene torch and also a high resistance to cutting and drilling tools.
- These known armored walls are generally made entirely by molding, the inserts being coated in the mass of metal, generally steel, refractory or not, constituting the basic component of said wall.
- the present invention aims to overcome all the aforementioned drawbacks.
- a composite armored wall possibly provided with one or more through orifices and mainly constituted, on the one hand, by an external plate having a high resistance to the conventional oxyacetylene torch and also a high resistance to cutting and drilling tools, wall characterized in that it is constituted, on the other hand, by a combustible intermediate plate, with smoke generation and generation of large flames, or resistant to the blowtorch with filler powder and, finally, by an inner plate made of an easily machinable material having a high resistance to the conventional blowtorch and comprising inserts having a high resistance to tools cutting and drilling, said plates being assembled together by means of connecting elements arranged, if necessary, at their lateral edges.
- the wall 1 is mainly constituted, on the one hand, by an outer plate 2 having a high resistance to the conventional oxyacetylene torch and also a high resistance to cutting and drilling tools, on the other hand, by a combustible intermediate plate 3, with smoke generation and generation of large flames, or resistant to the powder powder torch and, finally, by an inner plate 4 made of a material easily machinable having a high resistance to the conventional torch and comprising inserts 5 having a high resistance to cutting and drilling tools, said plates 2, 3 and 4 being assembled together by means of connecting elements 6 arranged, where appropriate if necessary, at their lateral edges.
- the resulting wall 1 cannot be pierced by means of a single type of cutting or perforating tools and therefore strongly thwarts any attempt at drilling.
- the outer plate 2 is made of weldable refractory steel, having a very high point resistance to the action of a conventional torch.
- the outer plate 2 is composed of a core 7, coming from molding, consisting of corundum or zircon grains integrated into a mass of copper and comprising, on the one hand, on its outer face, a layer of overmolded copper 8 and, on the other hand, on its inner face, a recess for the housing of the intermediate plate 3.
- the copper layer 8 is advantageously overmolded on the core 7 before the latter cools.
- the outer plate 1 thus obtained simultaneously exhibits very good resistance to a conventional torch attack due to the excellent thermal conductivity of the copper, which causes rapid and constant diffusion of the heat applied to the entire plate 1, and very good resistance to mechanical attack due to the nature of the material constituting the core 7.
- the intermediate plate 3 is advantageously made of graphite. This material counteracts the action of the intake powder torch by the retention of the previously molten metal forming a screen and by the initiation, under the effect of heat, of a slow combustion consuming significant quantities of oxygen, made of a sublimation of said graphite.
- the intermediate plate 3 can consist of a bituminous product, the combustion of which, on attack with a torch with filler powder, gives off, on the one hand, significant heat, annoying for the user of said torch and generates, on the other hand, open flames and opaque and irritating smoke.
- the inner plate 4 is advantageously a copper plate, constituting a final effective barrier against break-in, in particular break-in by means of a torch.
- the provision of at least one plate of easily machinable material, on at least one of the two lateral faces of the wall 1, makes it possible to rectify the latter with a view to adjusting its thickness or the parallelism of its two side faces, without the need for installation or special tools.

- the arrangement of the inserts 5, as described above, makes it possible to reinforce, in an effective and localized manner, the wall portions 1 constituting the privileged points of attack in the event of an attempted break-in, the positioning of said inserts 5 can be performed just before assembly of the different plates 2, 3 and 4, depending on the particular conditions of implementation of the wall 1 concerned or the required security requirements.
- the connecting elements 6 may be in the form of U-shaped staples, including an arm 12, extended by a corresponding core 13 , is secured to the outer plate 2 during the manufacture of the latter or during the assembly of the shielded wall 1, and the other arm 14 of which is attached to the free end of the core 13 after installation the intermediate plate 3 and the inner plate 4.
- the arms 12 of the staples 6 can either be welded to the outer plate 2, simultaneously with spacers 15 so as to form recesses for housing the intermediate plates 3, or be integrated into the mass of the outer plate 2 during the molding of the latter.
- the outer plate 2 is provided with a plurality of studs 16 at its internal face, passing through the intermediate plate 3 and the inner plate 4 and bearing on the rear face 17 of said inner plate 4.

- Said studs 16 can bear on the rear face 17 of the inner plate 4 by any appropriate means (washer, recess, threaded ends provided with clamping screen, etc.), however, according to a preferred embodiment, the free ends of the studs 16 are secured to an anchor plate 18 by welding at suitable orifices 19, said anchor plate 18 being applied against the rear face 17 of said inner plate 4 (FIG. 4).
- This arrangement makes it possible to prevent, during an attempt to pierce the wall 1, the successive removal of parts, or even of the whole, of the plates 2, 3 or 4 by separation from the remaining plates, whatever the location of the attack.
- the wall 1 can advantageously include an additional wall 20, made of a conducting material heat well and applied to the anchor plate 18, comprising a plurality of inserts 21, good thermal conductors, which can in particular be screwed and extending, through the anchor plate 18, into the mass of the plate interior 4.
- the privileged thermal bridges constituted by the inserts 21 make it possible to evacuate the calories, brought during a torch attack, from the place of attack at the level of the internal plate 4 towards the additional plate 20, where the heat can be distributed over the entire surface and be dissipated there.
- the outer plate 2, the studs 16 and the anchor plate 18 are made of weldable refractory steel
- the intermediate plate 3 consists of graphite and the inner plate 4
- the additional plate 20 and the inserts 21 are made in copper.
- the thicknesses of the various plates 2, 3 and 4 can be established as follows: a layer of copper 8 overmolded by approximately 10 mm, a core 7 made of corundum grains coated with copper of approximately 14 mm, an intermediate plate 3 of graphite of approximately 8 mm and, finally, an inner plate 4 of copper of approximately 8 mm.

Description
La présente invention concerne le domaine des dispositifs de sécurité, notamment la réalisation des conteneurs anti-effraction du type caisson ou chambre, et a pour objet une paroi blindée composite.The present invention relates to the field of security devices, in particular the production of burglar-resistant containers of the box or chamber type, and relates to a composite armored wall.
On connaît déjà différents types de parois blindées destinées à des coffres-forts ou des chambres fortes, comportant des inserts ou des couches de différentes natures en vue d'améliorer les caractéristiques de résistance desdites parois à l'effraction par des outils de coupe et/ou de perforation à action thermique ou mécanique.There are already known different types of armored walls intended for safes or vaults, comprising inserts or layers of different natures in order to improve the resistance characteristics of said walls against break-in by cutting tools and / or perforation with thermal or mechanical action.
Ainsi, le document DE-A-3 808 417 décrit une paroi blindée composite comprenant notamment une plaque extérieure présentant une résistance élevée au chalumeau oxyacétylénique classique et également une résistance élevée aux outils de coupe et de perçage.Thus, document DE-A-3 808 417 describes a composite armored wall comprising in particular an outer plate having a high resistance to the conventional oxyacetylene torch and also a high resistance to cutting and drilling tools.
Ces parois blindées connues sont généralement réalisées entièrement par moulage, les inserts étant enrobés dans la masse du métal, généralement de l'acier, réfractaire ou non, constituant le composant de base de ladite paroi.These known armored walls are generally made entirely by molding, the inserts being coated in the mass of metal, generally steel, refractory or not, constituting the basic component of said wall.
Néanmoins, la réalisation de telles parois entraîne des moulages complexes de très grandes dimensions ne pouvant être effectués que par des fondeurs spécialisés disposant des installations adaptées.Nevertheless, the production of such walls involves complex moldings of very large dimensions which can only be carried out by specialized founders with suitable installations.
En outre, il n'est pas possible de modifier la structure de la paroi après moulage en vue de l'adapter éventuellement à des conditions de mise en oeuvre spécifiques, différentes de celles prévues initialement lors de sa conception.In addition, it is not possible to modify the structure of the wall after molding in order to possibly adapt it to specific conditions of implementation, different from those initially planned during its design.
De plus, la mise en place des inserts dans le moule avant le coulage du métal de base et leur enrobage par le métal lors de la coulée génère des tensions internes dans la paroi résultant en des fissurations et des zones de fragilisation de ladite paroi, d'où résulte notamment une quantité importante de rebuts à la fabrication.In addition, the placement of the inserts in the mold before the base metal is poured and their coating with the metal during the casting generates internal tensions in the wall resulting in cracks and weakening zones of said wall, d 'which results in particular a significant amount of manufacturing scrap.
Par ailleurs, les parois de ce type réalisées en acier réfractaire, en tant que principal constituant, sont difficiles à usiner après leur moulage et ne peuvent être rectifiées, en vue de l'ajustement de leur dimension ou du parallélisme des faces internes et externes, qu'avec des machines et des outils spéciaux, très onéreux. De même, dans le cas d'applications particulières, nécessitant des épaisseurs de paroi variables, il faut obligatoirement procéder à des modifications et des changements importants au niveau de l'outil de production.Furthermore, the walls of this type made of refractory steel, as the main constituent, are difficult to machine after their molding and cannot be rectified, in order to adjust their size. or the parallelism of the internal and external faces, only with special machines and tools, very expensive. Likewise, in the case of particular applications, requiring variable wall thicknesses, it is essential to make major modifications and changes in the production tool.
Il est également connu d'appliquer des couches de matériaux présentant des propriétés de résitance spécifiques sur les faces opposées de deux plaques métalliques, puis d'assembler lesdites plaques sous des pressions et des températures très élevées. Ainsi, la réalisation de telles parois nécessite également la mise en oeuvre d'installations spéciales, très onéreuses, et la répartition uniforme du matériau aux propriétés de résistance spécifiques ne permet pas de protéger de manière renforcée les zones d'une telle paroi plus particulièrement exposées aux tentatives d'effraction, telles que par exemple les zones proximales d'orifices traversants.It is also known to apply layers of materials having specific resistance properties on the opposite faces of two metal plates, then to assemble said plates under very high pressures and temperatures. Thus, the production of such walls also requires the use of special, very expensive installations, and the uniform distribution of the material with specific resistance properties does not make it possible to protect in a reinforced manner the areas of such a wall which are more particularly exposed. burglary attempts, such as for example the proximal zones of through orifices.
Par ailleurs, les parois des types mentionnés ci-dessus ne répondent plus aux spécifications d'homologation actuellement en vigueur, à moins d'augmenter de manière considérable leur épaisseur, ce en raison du perfectionnement et de l'amélioration constante des performances des techniques et des procédés d'effraction. Enfin, aucune des parois connues des types précités ne propose de protection spécifique au niveau des ouvertures pouvant exister éventuellement dans lesdites parois.Furthermore, the walls of the types mentioned above no longer meet the approval specifications currently in force, unless their thickness is considerably increased, due to the improvement and constant improvement in the performance of the techniques and break-in procedures. Finally, none of the known walls of the aforementioned types offers specific protection at the level of the openings which may possibly exist in said walls.
La présente invention a pour but de pallier tous les inconvénients précités.The present invention aims to overcome all the aforementioned drawbacks.
A cet effet, elle a pour objet une paroi blindée composite, éventuellement pourvue d'un ou de plusieurs orifices traversants et principalement constituée, d'une part, par une plaque extérieure présentant une résistance élevée au chalumeau oxyacétylénique classique et également une résistance élevée aux outils de coupe et de perçage, paroi caractérisée en ce qu'elle est constituée, d'autre part, par une plaque intermédiaire combustible, avec dégagement de fumée et génération de flammes importants, ou résistant au chalumeau à poudre d'apport et, enfin, par une plaque intérieure en un matériau aisément usinable présentant une résistance élevée au chalumeau classique et comportant des inserts rapportés présentant une résistance élevée aux outils de coupe et de perçage, lesdites plaques étant assemblées entre elles au moyen d'éléments de liaison disposés, le cas échéant, au niveau de leurs bords latéraux.To this end, it relates to a composite armored wall, possibly provided with one or more through orifices and mainly constituted, on the one hand, by an external plate having a high resistance to the conventional oxyacetylene torch and also a high resistance to cutting and drilling tools, wall characterized in that it is constituted, on the other hand, by a combustible intermediate plate, with smoke generation and generation of large flames, or resistant to the blowtorch with filler powder and, finally, by an inner plate made of an easily machinable material having a high resistance to the conventional blowtorch and comprising inserts having a high resistance to tools cutting and drilling, said plates being assembled together by means of connecting elements arranged, if necessary, at their lateral edges.
L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à des modes de réalisation préférés, donnés à titre d'exemples non limitatifs et expliqués avec référence aux dessins schématiques annexés, dans lesquels :
- la figure 1 est une vue en élévation frontale de la paroi conforme à l'invention ;
- la figure 2 est une vue partielle en coupe à une échelle différente de la paroi représentée à la figure 1, selon un premier mode de réalisation de l'invention ;
- la figure 3 est une vue partielle en coupe à une échelle différente de la paroi représentée à la figure 1, selon un second mode de réalisation de l'invention, et,
- la figure 4 est une vue partielle en coupe d'une paroi selon une autre variante de réalisation de l'invention.

- FIG. 3 is a partial sectional view on a different scale of the wall shown in FIG. 1, according to a second embodiment of the invention, and,
- Figure 4 is a partial sectional view of a wall according to another alternative embodiment of the invention.
Conformément à l'invention, et comme le montrent les figures 1 à 3 des dessins annexés, la paroi 1 est principalement constituée, d'une part, par une plaque extérieure 2 présentant une résistance élevée au chalumeau oxyacétylénique classique et également une résistance élevée aux outils de coupe et de perçage, d'autre part, par une plaque intermédiaire 3 combustible, avec dégagement de fumée et génération de flammes importants, ou résistant au chalumeau à poudre d'apport et, enfin, par une plaque intérieure 4 en un matériau aisément usinable présentant une résistance élevée au chalumeau classique et comportant des inserts 5 rapportés présentant une résistance élevée aux outils de coupe et de perçage, lesdites plaques 2, 3 et 4 étant assemblées entre elles au moyen d'éléments de liaison 6 disposés, le cas échéant, au niveau de leurs bords latéraux.According to the invention, and as shown in Figures 1 to 3 of the accompanying drawings, the
Du fait des différentes natures des matériaux constitutifs des plaques 2, 3 et 4, de leurs propriétés de résistance spécifiques aux outils de coupe et de perçage thermiques ou mécaniques et de la combinaison ordonnée particulière desdites plaques 2, 3 et 4 entre elles en une structure laminée composite, la paroi 1 résultante ne peut être percée au moyen d'un unique type d'outils de coupe ou de perforation et contrarie, par conséquent, fortement toute tentative de perçage.Due to the different natures of the constituent materials of
En outre, l'assemblage des plaques 2, 3 et 4 au moyen d'éléments de liaison 6 permet de réaliser aisément des parois 1 d'épaisseurs et de constitutions variées, répondant à des propriétés particulières recherchées ou destinées à des applications données, sans nécessiter d'installation spécialisée et sans entraîner de modifications importantes au niveau de l'outil de production.In addition, the assembly of
Selon un premier mode de réalisation de l'invention, représenté à la figure 2 des dessins annexés, la plaque extérieure 2 est réalisée en acier réfractaire soudable, présentant une très grande résistance ponctuelle à l'action d'un chalumeau classique.According to a first embodiment of the invention, shown in Figure 2 of the accompanying drawings, the
Conformément à un second mode de réalisation de l'invention, représenté à la figure 3 des dessins annexés, la plaque extérieure 2 est composée d'une âme 7, venue de moulage, consistant en des grains de corindon ou de zircon intégrés dans une masse de cuivre et comportant, d'une part, sur sa face externe, une couche de cuivre 8 surmoulée et, d'autre part, sur sa face interne, un renfoncement pour le logement de la plaque intermédiaire 3.According to a second embodiment of the invention, shown in Figure 3 of the accompanying drawings, the
La couche de cuivre 8 est avantageusement surmoulée sur l'âme 7 avant le refroidissement de cette dernière.The
La plaque extérieure 1 ainsi obtenue présente simultanément une très bonne résistance à une attaque au chalumeau classique du fait de l'excellente conductibilité thermique du cuivre, qui entraîne une diffusion rapide et constante de la chaleur appliquée sur toute la plaque 1, et une très bonne résistance à une attaque mécanique dûe à la nature du matériau constituant l'âme 7.The
Selon une caractéristique de l'invention, et en vue d'interdire une effraction au moyen d'un chalumeau à poudre d'apport, la plaque intermédiaire 3 est avantageusement réalisée en graphite. Ce matériau contrarie l'action du chalumeau à poudre d'apport par la rétention du métal précédemment fondu formant écran et par l'amorce, sous l'effet de la chaleur, d'une combustion lente consommant des quantités d'oxygène importantes, du fait d'une sublimation dudit graphite.According to a characteristic of the invention, and in order to prohibit a break-in by means of a torch with filler powder, the
Conformément à une variante de réalisation de l'invention, la plaque intermédiaire 3 peut consister en un produit bitumeux, dont la combustion, lors d'une attaque au chalumeau à poudre d'apport, dégage, d'une part, une chaleur importante, gênante pour l'utilisateur dudit chalumeau et génère, d'autre part, des flammes vives et une fumée opaque et irritante.In accordance with an alternative embodiment of the invention, the
La plaque intérieure 4 est avantageusement une plaque en cuivre, constituant une ultime barrière efficace contre l'effraction, notamment l'effraction au moyen d'un chalumeau. En outre, la prévision d'au moins une plaque de matériau aisément usinable, sur l'une au moins des deux faces latérales de la paroi 1, permet de rectifier cette dernière en vue de l'ajustement de son épaisseur ou du parallélisme de ses deux faces latérales, sans nécessiter d'installation ou d'outils spéciaux.The
Selon une autre caractéristique de l'invention, les inserts 5 se présentent préférentiellement sous la forme de plaquettes métalliques recouvertes de poudre de diamant ou de plaquettes de zircon et sont enchâssés dans des rainures 9, ménagées dans la plaque intérieure 4, sur sa face tournée vers l'extérieur.According to another characteristic of the invention, the
Comme le montre la figure 1 des dessins annexés, représentant plus particulièrement une paroi 1 pouvant être utilisée en tant que paroi frontale d'un guichet automatique de banque, les inserts 5 sont essentiellement disposés au niveau des portions de paroi 1 reliant au moins deux orifices traversants 10 entre eux, au niveau des portions de paroi 1 attenantes aux orifices traversants 10, notamment au niveau des zones adjacentes aux angles desdits orifices traversants 10 de section parallélépipédique ou encore au niveau des portions de paroi 1 pouvant constituer, après découpage, en association avec un ou plusieurs orifices traversants des ouvertures de forme parallélépipédique de plus grandes dimensions 11 (en traits interrompus mixtes).As shown in Figure 1 of the accompanying drawings, more particularly showing a
La disposition des inserts 5, telle que décrite ci-dessus, permet de renforcer, de manière efficace et localisée, les portions de paroi 1 constituant les points d'attaque privilégiés en cas de tentative d'effraction, la mise en place desdits inserts 5 pouvant être effectuée juste avant assemblage des différentes plaques 2, 3 et 4, en fonction des conditions particulières de mise en oeuvre de la paroi 1 concernée ou des exigences de sécurité requises.The arrangement of the
Conformément à une caractéristique supplémentaire de l'invention, représentée aux figures 2 et 3 des dessins annexés, les éléments de liaison 6 peuvent se présenter sous la forme d'agrafes en forme de U, dont un bras 12, prolongé par une âme 13 correspondante, est solidarisé avec la plaque extérieure 2 lors de la fabrication de cette dernière ou lors de l'assemblage de la paroi 1 blindée, et dont l'autre bras 14 est rapporté sur l'extrémité libre de l'âme 13 après mise en place de la plaque intermédiaire 3 et de la plaque intérieure 4.In accordance with an additional characteristic of the invention, shown in Figures 2 and 3 of the accompanying drawings, the
Les bras 12 des agrafes 6 peuvent soit être soudés sur la plaque extérieure 2, simultanément avec des pièces d'écartement 15 de manière à constituer des renfoncements pour le logement des plaques intermédiaires 3, soit être intégrés dans la masse de la plaque extérieure 2 lors du moulage de cette dernière.The
Selon une autre variante de réalisation représentée à la figure 4 des dessins annexés, la plaque extérieure 2 est munie d'une pluralité de plots 16 au niveau de sa face interne, traversant la plaque intermédiaire 3 et la plaque intérieure 4 et prenant appui sur la face arrière 17 de ladite plaque intérieure 4.According to another alternative embodiment shown in Figure 4 of the accompanying drawings, the
Les plots 16 sont avantageusement formés d'un seul tenant avec la plaque extérieure 2 et répartis uniformément sur la face interne de cette dernière.The
Lesdits plots 16 peuvent prendre appui sur la face arrière 17 de la plaque intérieure 4 par tout moyen approprié (rondelle, décrochement, extrémités filetées pourvues d'écran de serrage, etc), néanmoins, selon un mode de réalisation préférentiel, les extrémités libres des plots 16 sont solidarisées avec une plaque d'ancrage 18 par soudage au niveau d'orifices 19 adaptés, ladite plaque d'ancrage 18 étant appliquée contre la face arrière 17 de ladite plaque intérieure 4 (figure 4).Said
La mise en oeuvre des plots 16, faisant office d'éléments de liaison 6, permet ainsi d'obtenir une structure plus unitaire de la paroi 1, les plaques intermédiaire 3 et intérieure 4 étant prises en sandwich et assemblées par serrage entre les deux parois 2 et 18, ces dernières présentant notamment une résistance mécanique et une dureté élevées.The implementation of the
Cette disposition permet d'empêcher, lors d'une tentative de perçage de la paroi 1, l'enlèvement successif de parties, voire de la totalité, des plaques 2, 3 ou 4 par désolidarisation avec les plaques restantes, ce quel que soit l'endroit de l'attaque.This arrangement makes it possible to prevent, during an attempt to pierce the
Selon une caractéristiques supplémentaire de l'invention, la paroi 1 peut comporter avantageusement une paroi supplémentaire 20, réalisée en un matériau conduisant bien la chaleur et appliquée sur la plaque d'ancrage 18, comportant une pluralité d'inserts 21, bons conducteurs thermiques, pouvant notamment être vissés et s'étendant, à travers la plaque d'ancrage 18, jusque dans la masse de la plaque intérieure 4.According to an additional characteristic of the invention, the
Les ponts thermiques privilégiés constitués par les inserts 21 permettent d'évacuer les calories, apportées lors d'une attaque au chalumeau, du lieu d'attaque au niveau de la plaque intérieure 4 vers la plaque supplémentaire 20, où la chaleur pourra être répartie sur l'ensemble de la surface et y être dissipée.The privileged thermal bridges constituted by the
De manière préférentielle, la plaque extérieure 2, les plots 16 et la plaque d'ancrage 18 sont réalisés en acier réfractaire soudable, la plaque intermédiaire 3 consiste en du graphite et la plaque intérieure 4, la plaque supplémentaire 20 et les inserts 21 sont réalisés en cuivre.Preferably, the
Grâce à l'invention, il est donc possible de réaliser une paroi 1 blindée composite, dont la fabrication ne nécessite aucune installation spéciale et dont la constitution peut être adaptée, avec une très grande souplesse, aux conditions de mise en oeuvre spécifiques de ladite paroi par simple variation des dimensions de ses plaques constitutives 2, 3 et 4 ou du nombre ou de la répartition de ses inserts 5.Thanks to the invention, it is therefore possible to produce a composite
Conformément à un mode de réalisation préféré de l'invention, les épaisseurs des différentes plaques 2, 3 et 4 peuvent s'établir comme suit : une couche de cuivre 8 surmoulée d'environ 10 mm, une âme 7 en grains de corindon enrobés de cuivre d'environ 14 mm, une plaque intermédiaire 3 en graphite d'environ 8 mm et, enfin, une plaque intérieure 4 en cuivre d'environ 8 mm.In accordance with a preferred embodiment of the invention, the thicknesses of the
Ainsi l'invention permet de réaliser des parois blindées relativement minces, éventuellement munies d'ouvertures, dont la résistance à l'effraction est nettement supérieure à celle des parois connues de l'art antérieur, notamment
les parois monolithiques, constituées par un matériau de base coulé.Thus the invention makes it possible to produce relatively thin armored walls, possibly provided with openings, the resistance to burglary of which is clearly greater than that of the walls known from the prior art, in particular
the monolithic walls, made of a material of cast base.
En conséquence, les parois conformes à l'invention satisfont aux exigences des normes de sécurité françaises et étrangères les plus contraignantes, du fait notamment de leurs différents matériaux constitutifs et de leur structure particulière.Consequently, the walls in accordance with the invention meet the requirements of the most restrictive French and foreign safety standards, in particular because of their different constituent materials and their particular structure.
