Description

DISPOSITIF DE SIEGE A DOSSIER SECTIONNEL POUR HABITACLE DE  SECTIONAL FOLDING SEAT DEVICE FOR COCKPIT
VEHICULE  VEHICLE
[0001] La présente invention revendique la priorité de la demande française 1 158035 déposée le 9 septembre 201 1 dont le contenu (texte, dessins et revendications) est ici incorporé par référence. The present invention claims the priority of the French application 1 158035 filed September 9, 201 1 whose content (text, drawings and claims) is here incorporated by reference.
[ooo2] L'invention concerne des dispositifs pour habitacle de véhicules, notamment automobiles utilitaires et, en particulier, des dispositifs comportant au moins un siège escamotable. [Ooo2] The invention relates to devices for the passenger compartment of vehicles, especially commercial automobiles and, in particular, devices comprising at least one retractable seat.
[ooo3] Aujourd'hui, les usages d'un véhicule utilitaire doivent permettre la souplesse de plus en plus grande en vue d'utiliser, par exemple, tout ou partie du volume du ou des sièges passagers, qu'ils soient latéraux ou centraux, afin de pouvoir transporter des charges de grande longueur. [Ooo3] Today, the uses of a commercial vehicle must allow greater flexibility to use, for example, all or part of the volume of the passenger seat (s), whether lateral or central , in order to be able to transport loads of great length.
[ooo4] A cette fin, il existe actuellement des dispositifs pour habitacle de véhicules qui rendent possible un dégagement d'un volume en partie inférieure au niveau d'un siège passager. De tels dispositifs sont, par exemple, décrits dans le document FR 2 949 721 . [Ooo4] For this purpose, there are currently vehicle interior devices that make it possible to release a volume at the bottom of a passenger seat. Such devices are, for example, described in the document FR 2 949 721.
[ooo5] Dans le dispositif décrit dans ce document, un siège passager comporte des béquilles de liaison de l'assise à un soubassement du véhicule se repliant contre une face inférieure de ladite assise. Une fois les béquilles repliées, l'assise est basculée contre le dossier. Puis, le siège est déplacé à coulissement vers le haut le long d'une paroi de séparation entre l'habitacle et le compartiment de chargement, dégageant ainsi une ouverture basse dans la paroi de séparation et un volume sous le siège ainsi relevé afin de recevoir des charges de grande longueur positionnées à cheval entre le compartiment de chargement et l'habitacle. [Ooo5] In the device described in this document, a passenger seat comprises support legs of the seat to a base of the vehicle folding against a lower face of said seat. Once the crutches folded, the seat is tilted against the backrest. Then, the seat is slid upwardly along a partition wall between the passenger compartment and the loading compartment, thus releasing a low opening in the partition wall and a volume under the seat thus raised to receive long loads positioned between the loading compartment and the passenger compartment.
[ooo6] Toutefois, un tel agencement ne donne pas entièrement satisfaction, car, en position haute, le siège gêne, d'une part, la visibilité latérale du conducteur et, d'autre part, le passager éventuellement installé sur l'autre siège passager. [0007] Un but de l'invention est de fournir un dispositif pour habitacle de véhicule comportant au moins un siège escamotable réduisant la gêne du conducteur et/ou du passager de l'autre siège. [Ooo6] However, such an arrangement is not entirely satisfactory because, in the high position, the seat hinders, on the one hand, the lateral visibility of the driver and, on the other hand, the passenger possibly installed on the other seat passenger. An object of the invention is to provide a vehicle interior device comprising at least one retractable seat reducing the discomfort of the driver and / or the passenger of the other seat.
[ooo8] A cette fin, il est prévu, selon l'invention, un dispositif pour habitacle de véhicule comprenant au moins un siège comportant une assise accouplée à un dossier, le siège étant apte à être déplacé entre une position basse d'occupation par un passager et une position haute de dégagement à l'intérieur de l'habitacle de véhicule, caractérisé en ce que le dossier comporte une série de sections formant une chaîne, articulées les unes par rapport aux autres deux à deux, chacune des sections étant montée mobile à coulissement à des moyens de déplacement à coulissement solidaires du véhicule. [Ooo8] For this purpose, it is provided, according to the invention, a vehicle interior device comprising at least one seat having a seat coupled to a backrest, the seat being able to be moved between a low position of occupation by a passenger and a high clearance position inside the vehicle cabin, characterized in that the backrest comprises a series of sections forming a chain, articulated relative to each other two by two, each of the sections being mounted slidably movable to sliding displacement means integral with the vehicle.
[ooo9] Ainsi, le dossier formé d'une chaîne d'éléments suit un chemin défini par les moyens de déplacement à coulissement solidaires du véhicule, ce qui permet de positionner un siège du dispositif ainsi conformé contre les parois de l'habitacle tout en réduisant la gêne du conducteur (visibilité latérale) et/ou du passager éventuel de l'autre siège passager. [0oo9] Thus, the file formed of a chain of elements follows a path defined by the sliding means of solidarity of the vehicle, which allows to position a seat of the device and shaped against the walls of the passenger compartment while reducing driver discomfort (sideways visibility) and / or the potential passenger from the other passenger seat.
[ooi o] Avantageusement, mais facultativement, le dispositif comporte au moins l'une des caractéristiques suivantes : l'assise est accouplée au dossier de manière articulée par rapport à une section d'extrémité de la chaîne ; deux sections adjacentes sont articulées l'une par rapport à l'autre au moyen d'au moins une bielle ; deux sections adjacentes sont articulées l'une par rapport à l'autre au moyen d'au moins une charnière ; les moyens de déplacement à coulissement comportent une butée basse permettant de retenir la série de sections quand le siège est dans la position basse d'occupation ; les moyens de déplacement à coulissement comportent au moins un rail ou une glissière ; le rail ou la glissière est rectiligne et s'étend de bas en haut le long d'une paroi de l'habitacle ; · le rail ou la glissière comporte une partie courbe de sorte à s'étendre de bas en haut le long de d'une paroi de l'habitacle puis le long d'un pavillon de l'habitacle ; le dispositif comporte des moyens de verrouillage du siège en position haute de dégagement ; « le siège comprend des éléments de fixation de l'assise avec un soubassement de l'habitacle ; les éléments de fixation sont des bielles ou des vérins ; le dispositif comporte en outre des moyens d'assistance agencés de sorte à faciliter le déplacement des sections ; et, · les moyens d'assistance comportent un élément choisi dans un groupe comportant au moins un vérin, un mécanisme à contrepoids, un ressort de rappel et un moteur électrique. [Ooi o] Advantageously, but optionally, the device comprises at least one of the following features: the seat is coupled to the backrest in an articulated manner relative to an end section of the chain; two adjacent sections are hinged relative to each other by means of at least one connecting rod; two adjacent sections are hinged relative to each other by means of at least one hinge; the sliding displacement means comprise a bottom stop for retaining the series of sections when the seat is in the low occupancy position; the sliding displacement means comprise at least one rail or a slide; the rail or slide is rectilinear and extends upwardly along a wall of the passenger compartment; The rail or slide has a curved portion so as to extend upwardly along a wall of the passenger compartment and then along a roof of the passenger compartment; the device comprises means for locking the seat in the upper position of disengagement; "The seat comprises elements for fixing the seat with a base of the passenger compartment; the fastening elements are connecting rods or jacks; the device further comprises assistance means arranged to facilitate the movement of the sections; and · the assistance means comprise an element selected from a group comprising at least one jack, a counterweight mechanism, a return spring and an electric motor.
[ooi i] Il est aussi prévu, selon l'invention, un véhicule comportant au moins un dispositif présentant au moins l'une des caractéristiques précédentes de sorte à pouvoir transporter des charges de grande longueur. [Ooi i] It is also provided, according to the invention, a vehicle comprising at least one device having at least one of the above characteristics so as to be able to transport loads of great length.

Figure 4 is a schematic view illustrating a first embodiment of a connection between two sections of the embodiment of the invention of Figure 1; and FIG. 5 is a schematic view of an alternative embodiment of the connection between two sections of FIG. 4.
[0013] En référence aux figures 1 à 3, un véhicule 1 , ici un véhicule automobile utilitaire, comporte un compartiment de chargement 2 présentant un plancher 3. Le compartiment de chargement 2 est situé dans une partie arrière du véhicule 1 . En outre, le véhicule 1 comporte un habitacle 5 en partie avant, adjacent au compartiment de chargement 2 et séparé de celui-ci par une paroi de séparation 4. Dans l'habitacle de véhicule 5, est installé un dispositif 10 selon l'invention. Le dispositif 10 comporte un siège comportant lui-même une assise 12 et un dossier 1 1 , l'assise 12 étant accouplée au dossier 1 1 . D'autre part, l'habitacle de véhicule 5 comporte un soubassement 6 ainsi qu'un pavillon 7. Referring to Figures 1 to 3, a vehicle 1, here a utility vehicle, has a load compartment 2 having a floor 3. The load compartment 2 is located in a rear portion of the vehicle 1. In addition, the vehicle 1 comprises a passenger compartment 5 in the front part, adjacent to the load compartment 2 and separated therefrom by a partition wall 4. In the passenger compartment 5, is installed a device 10 according to the invention . The device 10 comprises a seat which itself comprises a seat 12 and a backrest 11, the seat 12 being coupled to the backrest 11. On the other hand, the passenger compartment 5 comprises a base 6 and a roof 7.
[0014] En référence à la figure 1 , le dispositif 10 selon l'invention est une position basse d'occupation, position dans laquelle le siège du dispositif peut être occupé par un passager du véhicule. Le dossier 1 1 du siège comporte une série de sections 1 1 1 agencées de sorte à former une chaîne. Deux sections adjacentes 1 1 1 de la chaîne sont articulées l'une par rapport à l'autre par des moyens d'articulation 1 12. Ici, à titre illustratif, les sections 1 1 1 sont au nombre de quatre. Chacune des sections 1 1 1 est montée mobile à coulissement à des moyens de déplacement à coulissement 41 , 1 10 solidaires du véhicule. Les moyens de déplacement à coulissement comportent des moyens formant rail 41 qui sont fixés sur la paroi de séparation 4, en s'étendant le long de celle-ci dans une direction allant de bas en haut. Dans leur partie supérieure, les moyens formant rail 41 , présentent une partie courbe afin qu'une extrémité des moyens formant rail 41 vienne s'étendre en regard du pavillon 7 de l'habitacle 5 du véhicule. Chacune des sections 1 1 1 est montée mobile à coulissement dans les moyens formant rail 41 à l'aide de moyens formant ergot 1 10 qui vont coopérer avec les moyens formant rail 41 afin de permettre un déplacement à coulissement le long des moyens formant rail 41 de chacune des sections 1 1 1 formant le dossier 1 1 du dispositif 10 selon l'invention. Des moyens formant butée sont aménagés à chacune des extrémités des moyens formant rail 41 , les moyens formant butée situés à une extrémité inférieure des moyens formant rail 41 permettent de retenir, vers le bas, une section 1 1 1 du dossier 1 1 , située à une extrémité basse du dossier 1 1 , lorsque le dispositif 10 selon l'invention est dans la position basse d'occupation. [0015] En référence aux figures 4 et 5, les moyens d'articulation 1 12 sont constitués d'une bielle 1 12 dont chacune des extrémités est articulée au niveau de sa liaison avec chacune des sections 1 1 1 adjacentes. Dans une variante de réalisation, les moyens d'articulation forment une charnière 1 13 reliant deux sections 1 1 1 adjacentes du dossier 1 1 du dispositif 10 selon l'invention. [0016] De nouveau en référence à la figure 1 , l'assise 12 du siège du dispositif 10 selon l'invention, lorsque ce dernier est dans la position basse d'occupation, est orientée sensiblement horizontalement. Au niveau d'une extrémité arrière de l'assise 12, l'assise 12 est accouplée au dossier 1 1 , en particulier à la section 1 1 1 située à l'extrémité basse du dossier 1 1 . Cet accouplement est réalisé par des moyens d'articulation 1 12 similaires à ceux liant deux sections adjacentesReferring to Figure 1, the device 10 according to the invention is a low occupancy position, position in which the seat of the device can be occupied by a passenger of the vehicle. The seat back 1 1 comprises a series of sections 1 1 1 arranged so as to form a chain. Two adjacent sections 1 1 1 of the chain are hinged relative to each other by hinge means 1 12. Here, for illustrative purposes, the sections 1 1 1 are four in number. Each of the sections 1 1 1 is slidably mounted to sliding displacement means 41, 1 10 integral with the vehicle. The sliding displacement means comprise means forming a rail 41 which are attached to the partition wall 4, extending along it in a direction from bottom to top. In their upper part, the rail means 41 have a curved portion so that one end of the rail means 41 comes to extend facing the horn 7 of the passenger compartment 5 of the vehicle. Each of the sections 1 1 1 is slidably mounted in the rail means 41 by means of pin means 10 which will cooperate with the rail means 41 to allow sliding movement along the rail means 41. of each of the sections 1 1 1 forming the folder 1 1 of the device 10 according to the invention. Stopper means are provided at each of the ends of the rail means 41, the stop means at a lower end of the rail means 41 for holding, at the bottom, a section 1 1 1 of the backrest 1 1, located at a low end of the back 1 1, when the device 10 according to the invention is in the low occupancy position. Referring to Figures 4 and 5, the hinge means 1 12 are constituted by a connecting rod 1 12, each of the ends is articulated at its connection with each of the adjacent sections 1 1 1. In an alternative embodiment, the hinge means form a hinge January 13 connecting two sections 1 1 1 adjacent file 1 1 1 of the device 10 according to the invention. Again with reference to Figure 1, the seat 12 of the seat of the device 10 according to the invention, when the latter is in the low position of occupation, is oriented substantially horizontally. At a rear end of the seat 12, the seat 12 is coupled to the back 1 1, in particular to section 1 1 1 located at the bottom end of the back 1 1. This coupling is achieved by hinge means 1 12 similar to those linking two adjacent sections
1 1 1 du dossier 1 1 . D'autre part, au niveau d'une extrémité avant, l'assise 12 est liée par une liaison pivot à des éléments de fixation 13 qui permettent de fixer l'assise 12 au soubassement 6 de l'habitacle 5 de véhicule. Ces éléments de fixation peuvent être des bielles ou des vérins dont une extrémité supérieure est liée à l'extrémité avant de l'assise 12 du siège du dispositif 10 selon l'invention et l'autre extrémité inférieure est liée par une liaison pivot au soubassement 6 de l'habitacle 5 de véhicule. La liaison pivot entre les éléments de fixation et le soubassement 6 est située au niveau d'une verticale sous les moyens formant rail 41 , en arrière du siège du dispositif 10 selon l'invention. Les éléments de fixation 13 peuvent faire varier une longueur entre leurs deux extrémités lors du passage du siège du dispositif 10 selon l'invention de la position basse d'occupation à la position haute de dégagement. De ce fait, les éléments de fixation 13 présentent alors des moyens de verrouillage de cette longueur afin de maintenir l'assise, d'une part, en position horizontale lorsque le siège du dispositif 10 selon l'invention est dans la position basse d'occupation du siège par un passager et, d'autre en position relevée lorsque le siège du dispositif 10 selon l'invention est dans la position haute de dégagement. 1 1 1 of the file 1 1. On the other hand, at a front end, the seat 12 is connected by a pivot connection to the fastening elements 13 which allow to fix the seat 12 to the base 6 of the passenger compartment 5 of the vehicle. These fixing elements may be rods or jacks whose one upper end is connected to the front end of the seat 12 of the seat of the device 10 according to the invention and the other lower end is connected by a pivot connection to the underbody. 6 of the vehicle cockpit 5. The pivot connection between the fasteners and the Underbody 6 is situated at a vertical level under the rail means 41, behind the seat of the device 10 according to the invention. The fastening elements 13 may vary a length between their two ends during the passage of the seat of the device 10 according to the invention from the low occupancy position to the high position of disengagement. As a result, the fastening elements 13 then have locking means of this length in order to maintain the seat, on the one hand, in a horizontal position when the seat of the device 10 according to the invention is in the low position of seat occupancy by a passenger and, in other position in raised position when the seat of the device 10 according to the invention is in the high position of release.
[0017] En référence maintenant à la figure 2, le dispositif 10 selon l'invention se trouve dans une position intermédiaire entre la position basse d'occupation du siège décrite précédemment en référence à la figure 1 et la position haute de dégagement que nous décrirons ultérieurement en référence à la figure 3. Un mouvement de déplacement F le long des moyens formant rail 41 peut être appliqué au siège afin de faire coulisser les différentes sections 1 1 1 du dossierReferring now to Figure 2, the device 10 according to the invention is in an intermediate position between the low position occupancy of the seat described above with reference to Figure 1 and the high position of clearance that we describe Fig. 3. A movement of movement F along the rail means 41 may be applied to the seat to slide the various sections 1 1 1 of the backrest.
1 1 le long des moyens formant rail 41 . Les moyens d'articulation 1 12 entre deux sections adjacentes 1 1 1 du dossier 1 1 permettent à ce dernier, lors du coulissement le long des moyens formant rail 41 , de suivre la partie courbe desdits moyens formant rail 41 . La dernière section 1 1 1 formant l'extrémité basse du dossier entraîne dans son mouvement l'extrémité arrière de l'assise1 1 along the rail means 41. The hinge means 1 12 between two adjacent sections 1 1 1 of the backrest 1 1 allow the latter, during sliding along the rail means 41, to follow the curved portion of said rail means 41. The last section 1 1 1 forming the low end of the back causes in its movement the rear end of the seat
12 à laquelle elle est liée par des moyens d'articulation 1 12. Alors que l'extrémité avant de l'assise 12 est guidée, lors de ce déplacement, par les éléments de fixation 13, l'assise 12 bascule vers la paroi de séparation 4 de sorte qu'une face inférieure de l'assise 12 vienne en regard de la paroi 4 de séparation. 12 to which it is connected by hinge means 1 12. While the front end of the seat 12 is guided, during this movement, by the fastening elements 13, the seat 12 tilts towards the wall of separation 4 so that a lower face of the seat 12 comes opposite the partition wall 4.
[0018] En référence à la figure 3, le mouvement de coulissement s'est prolongé jusqu'à ce que les moyens formant ergot 1 12 de la section 1 1 1 d'extrémité haute du dossier 1 1 viennent en butée avec les moyens formant butée situés à l'extrémité supérieure des moyens formant rail 41 . Dans cette position haute de dégagement, l'assise 12 est dans l'alignement avec la section 1 1 1 formant l'extrémité inférieure du dossier 1 1 . L'assise 12 occupe alors en partie la place occupée par le dossier 1 1 lorsque le siège du dispositif 10 selon l'invention est dans la position basse d'occupation. D'autre part, une partie des sections 1 1 1 formant le dossier 1 1 sont positionnées le long du pavillon 7 de l'habitacle 5 de véhicule, en regard de celui-ci. Un système de verrouillage assure le maintien du dossier et de l'assise dans cette position haute de dégagement du dispositif 10 selon l'invention. L'espace inférieur de l'habitacle 5 du véhicule est alors dégagé, permettant d'introduire et de transporter des charges 8 de très grande longueur qui se retrouvent alors à cheval entre le compartiment de chargement 2 et l'habitacle 5 de véhicule. [0019] En variante de réalisation, les moyens formant rail 41 ne présentent pas de partie courbe et sont rectilignes en s'étendant de manière sensiblement verticalement le long de la paroi 4 de séparation. Dans ce cas, afin d'augmenter la hauteur disponible pour des charges de grande longueur, il est possible de diminuer une longueur "dépliée" du siège du dispositif 10 selon l'invention en retirant un appui-tête du dossier 1 1 , l'appui-tête formant la section 1 1 1 située à l'extrémité haute du dossier 1 1 . De nouveau, un système de verrouillage est prévu afin d'assurer le maintien du siège lorsque le dispositif 10 selon l'invention est en position haute de dégagement. Un tel système peut être, par exemple, un dispositif de réglage de l'appui-tête prévu dans le haut du dossier 1 1 venant s'arrimer à une broche descendant du pavillon 7 de l'habitacle 5 de véhicule. D'autre part, dans ce cas d'un rail rectiligne, le nombre de sections 1 1 1 et de moyens d'articulation 1 12 peut être diminué. Referring to Figure 3, the sliding movement has continued until the means forming pin 1 12 of the section 1 1 1 high end of the backrest 1 1 abut with the means forming stop located at the upper end of the rail means 41. In this high position of clearance, the seat 12 is in alignment with the section 1 1 1 forming the lower end of the back 1 1. The seat 12 then occupies part of the space occupied by the backrest 1 1 when the seat of the device 10 according to the invention is in the low occupancy position. On the other hand, a portion of the sections 1 1 1 forming the backrest 1 1 are positioned along the roof 7 of the passenger compartment 5 of vehicle, facing it. A locking system maintains the backrest and the seat in this high position of release of the device 10 according to the invention. The lower space of the passenger compartment 5 of the vehicle is then released, to introduce and transport loads 8 of great length which are then straddling between the load compartment 2 and the passenger compartment 5 of the vehicle. In an alternative embodiment, the rail means 41 do not have a curved portion and are straight extending substantially vertically along the partition wall 4. In this case, in order to increase the height available for loads of great length, it is possible to reduce an "unfolded" length of the seat of the device 10 according to the invention by removing a headrest from the backrest 1 1, the Headrest forming section 1 1 1 located at the high end of the backrest 1 1. Again, a locking system is provided to maintain the seat when the device 10 according to the invention is in the upper position of release. Such a system may be, for example, a device for adjusting the headrest provided in the top of the backrest 1 1 which is docked to a pin down from the roof 7 of the passenger compartment 5 of the vehicle. On the other hand, in this case of a rectilinear rail, the number of sections 1 1 1 and articulation means 1 12 can be decreased.
[0020] En alternative, le dispositif 10 selon l'invention comporte des moyens d'assistance agencés de sorte à faciliter le déplacement des sections lors d'un coulissement le long des moyens de déplacement à coulissement. Ces moyens d'assistance peuvent être des vérins, ou un mécanisme à contrepoids, ou des ressorts de rappel ou encore des moteurs électriques. Ainsi, les moyens d'assistance permettent, lorsque le dispositif 10 selon l'invention passe de la position basse d'occupation à la position haute de dégagement, de compenser tout ou partie du poids du dossier et de l'assise formant le siège. Dans le sens inverse, l'action des moyens d'assistance permet de contrer la gravité et de ralentir la descente du dispositif 10 selon l'invention, augmentant par ailleurs la sécurité pour l'utilisateur. Alternatively, the device 10 according to the invention comprises assistance means arranged to facilitate the displacement of the sections during sliding along the sliding displacement means. These assistance means may be cylinders, or a counterweight mechanism, or return springs or electric motors. Thus, the assistance means allow, when the device 10 according to the invention passes from the low occupancy position to the high position of clearance, to offset all or part of the weight of the backrest and the seat forming seat. In the opposite direction, the action of the assistance means makes it possible to counter gravity and to slowing the descent of the device 10 according to the invention, further increasing the security for the user.
[0021 ] Nous allons maintenant décrire brièvement une utilisation du dispositif 10 selon l'invention. Dans un premier temps, l'utilisateur déverrouille le dispositif 10 selon l'invention et imprime aux sections 1 1 1 du dossier 1 1 un mouvement de coulissement F. Par coopération des moyens formant ergot 1 10 des différentes sections 1 1 1 du dossier 1 1 et des moyens formant rail 41 , l'ensemble des sections 1 1 1 coulisse le long des moyens formant rail 41 entraînant dans leur mouvement l'extrémité arrière de l'assise 12 du siège du dispositif 10 selon l'invention. L'extrémité avant de l'assise 12 est alors guidée par les éléments de fixation 13 afin de basculer puis venir plaquer l'assise 12 en regard de la paroi de séparation 4. Leur mouvement prend fin lorsque la section 1 1 1 d'extrémité haute du dossier 1 1 vient en butée contre les moyens formant butée situés à l'extrémité supérieure des moyens formant rail 41 . L'utilisateur verrouille alors le dispositif 10 selon l'invention dans cette position haute de dégagement. We will now briefly describe a use of the device 10 according to the invention. In a first step, the user unlocks the device 10 according to the invention and prints to the sections 1 1 1 of the folder 1 1 a sliding movement F. By cooperation of the lug forming means 1 10 of the various sections 1 1 1 of the folder 1 1 and rail means 41, the set of sections 11 1 slides along the rail means 41 causing in their movement the rear end of the seat 12 of the seat of the device 10 according to the invention. The front end of the seat 12 is then guided by the fastening elements 13 to tilt and then come to press the seat 12 opposite the partition wall 4. Their movement ends when the end section 1 1 1 upper back 1 1 abuts against the stop means located at the upper end of the rail means 41. The user then locks the device 10 according to the invention in this high release position.
[0022] Bien entendu, il est possible d'apporter à l'invention de nombreuses modifications sans sortir pour autant du cadre de celle-ci. Of course, it is possible to bring to the invention many changes without departing from the scope thereof.
