Description

La présente invention concerne un dispositif de réglage de l'inclinaison de l'assise d'un siège par rapport à un support de ladite assise surmontant le pied du siège. Un tel dispositif permet à l'utilisateur d'obtenir une pente variable de l'assise en déplaçant la partie arrière de celle-ci, c'est-à-dire la portion qui est située au voisinage du dossier du siège, par basculement par rapport à la partie avant.The present invention relates to a device for adjusting the inclination of the base of a seat relative to a support of said seat surmounting the foot of the seat. Such a device allows the user to obtain a variable slope of the seat by moving the rear part thereof, that is to say the portion which is located in the vicinity of the seat back, by tilting by compared to the front part.

Le système de l'invention ne permet pas un réglage continu de la pente, mais un fonctionnement discret avec deux valeurs, c'est-à-dire qu'il comporte en réalité deux positions stables : d'une part une position initiale dans laquelle l'assise possède une orientation inclinée vers l'arrière d'environ -2° par rapport à l'horizontale et d'autre part, après un basculement vers l'avant de l'ordre de +5°, une position finale qui s'écarte de l'horizontale, dans le sens horaire, d'environ 3°.The system of the invention does not allow continuous adjustment of the slope, but discrete operation with two values, that is to say that it actually comprises two stable positions: on the one hand an initial position in which the seat has an orientation inclined towards the rear of approximately -2° compared to the horizontal and on the other hand, after a forward tilt of around +5°, a final position which 'deviates from the horizontal, clockwise, by approximately 3°.

La plupart des sièges, notamment de bureau, comportent la possibilité d'un tel réglage angulaire de l'assise, réalisé au moyen de systèmes mécaniques de pivotement très variables. Dans la pratique, les parties matelassées au contact desquelles l'utilisateur repose, formant l'assise proprement dite, sont séparées du piètement ou pied du siège par une platine mécanique plus ou moins complexe, intégrant le cas échéant plusieurs possibilités de réglage du dossier et de l'assise.Most chairs, particularly office seats, include the possibility of such angular adjustment of the seat, carried out by means of highly variable mechanical pivoting systems. In practice, the padded parts in contact with which the user rests, forming the seat itself, are separated from the base or foot of the seat by a more or less complex mechanical plate, integrating where necessary several possibilities for adjusting the backrest and of the seat.

Très schématiquement, les pieds de sièges par exemple de bureau sont souvent reliés en partie basse d'un support rigide intégrant lesdits moyens de réglage mécaniques du siège, support en partie haute duquel est placée une plate-forme revêtue de la garniture matelassée propre à l'assise. Lorsqu'ils sont prévus, les mécanismes de réglage de l'inclinaison de l'assise présentent des solutions techniques très diverses, qui dépendent des configurations des supports, des différents types de réglages éventuellement prévus, des matériaux choisis pour leur mise en œuvre, etc.Very schematically, the legs of seats, for example office seats, are often connected in the lower part of a rigid support integrating said mechanical adjustment means of the seat, support in the upper part of which is placed a platform covered with the quilted padding specific to the seat. When they are provided, the mechanisms for adjusting the inclination of the seat present very diverse technical solutions, which depend on the configurations of the supports, the different types of adjustments possibly provided, the materials chosen for their implementation, etc. .

Ainsi, dans un document DE 10 2009 051 119 , le support de siège relié au piètement présente un dispositif de réglage de l'inclinaison de l'assise du siège basé sur un excentrique relié à l'assise via un système de transmission et supporté de manière pivotante sur le support de siège. Une commande rotative est reliée à l'excentrique et le système de transmission est articulé sur l'assise, l'excentrique et le système de transmission pouvant pivoter l'un par rapport à l'autre.So, in a document DE 10 2009 051 119 , the seat support connected to the base has a device for adjusting the inclination of the seat base based on an eccentric connected to the seat via a transmission system and pivotally supported on the seat support. A rotary control is connected to the eccentric and the transmission system is articulated on the seat, the eccentric and the transmission system being able to pivot relative to each other.

Dans un document EP 1 992 254 , un dispositif permettant de modifier la position angulaire d'une assise par rapport à un support fixe de siège comprend des moyens à came sous forme d'un secteur angulaire doté d'une fenêtre curviligne, lesdits moyens pouvant être commandés en rotation par un utilisateur pour agir sur un ergot de l'assise.In a document EP 1 992 254 , a device making it possible to modify the angular position of a seat relative to a fixed seat support comprises cam means in the form of an angular sector provided with a curvilinear window, said means being able to be controlled in rotation by a user to act on a lug on the seat.

Le présent déposant a également déjà développé une solution, objet du document WO2008/155470 , portant sur un système mécanique de réglage de l'inclinaison de l'assise d'un siège par rapport à un support de ladite assise. En substance, une coque supportant la partie rembourrée de l'assise peut être commandée en rotation par rapport au support selon un axe transversal situé vers l'avant de la coque. Ce système comprend deux pièces actionnées via un arbre prismatique, pièces dans lesquelles un évidemment coopérant avec un ergot permet de déplacer la coque d'assise par rapport au support.The present applicant has also already developed a solution, subject of the document WO2008/155470 , relating to a mechanical system for adjusting the inclination of the seat base relative to a support of said seat. In essence, a shell supporting the padded part of the seat can be controlled to rotate relative to the support along a transverse axis located towards the front of the shell. This system includes two parts operated via a prismatic shaft, parts in which a recess cooperating with a lug allows the seat shell to be moved relative to the support.

L'invention objet de cette demande a trait à une autre configuration encore de dispositif de modification de l'inclinaison de l'assise, dont la conception est d'une part très simple, facilitant le montage du siège, et est d'autre part conçue pour que la stabilité positionnelle des deux positions d'inclinaison possibles soit renforcée par le poids de l'utilisateur du siège.The invention which is the subject of this application relates to yet another configuration of a device for modifying the inclination of the seat, the design of which is on the one hand very simple, facilitating the assembly of the seat, and is on the other hand designed so that the positional stability of the two possible reclining positions is reinforced by the weight of the seat user.

Le dispositif de l'invention comporte classiquement :

  • un cadre socle de l'assise matelassée, comportant deux cornières longitudinales et deux arbres transversaux reliant les cornières et situés au voisinage de leurs extrémités, ledit cadre étant mobile en rotation par rapport au support au moyen d'un desdits arbres transversaux monté libre en rotation sur le support ;
  • au moins deux cames solidarisées à un arbre rotatif commandé par des moyens de commande manuels et apte à déplacer angulairement le cadre de l'assise entre une première et une seconde positions angulaires stables par rapport au support.
The device of the invention conventionally comprises:
  • a base frame of the padded seat, comprising two longitudinal angles and two transverse shafts connecting the angles and located near their ends, said frame being movable in rotation relative to the support by means of one of said transverse shafts mounted free to rotate on the support;
  • at least two cams secured to a rotating shaft controlled by manual control means and capable of angularly moving the seat frame between a first and a second stable angular positions relative to the support.

Selon l'invention, le dispositif de réglage de l'inclinaison est tel qu'il comporte des cames disques à excentrique coopérant chacune avec au moins deux ergots suiveurs dépassant des cornières et comportant au moins un profil extérieur et au moins un profil intérieur de guidage des ergots entre des butées agencées dans lesdits profils pour stabiliser le cadre en les deux positions angulaires stables, chaque profil d'une came coopérant avec un unique ergot.According to the invention, the inclination adjustment device is such that it comprises eccentric disk cams each cooperating with at least two follower lugs projecting from the angles and comprising at least one exterior profile and at least one interior guide profile lugs between stops arranged in said profiles to stabilize the frame in the two angular positions stable, each profile of a cam cooperating with a single lug.

En fait, le positionnement des ergots suiveurs sur le cadre, l'orientation des cames excentriques lorsqu'elles sont fixées à l'arbre rotatif et la conception des profils sont prévus de telle sorte que lesdits ergots puissent être guidés entre les deux positions angulaires voulues pour l'assise. Les profils sont ensuite tracés de manière à ce que le poids de l'utilisateur assis sur le siège exerce une action renforçant l'appui ergot/butée dans le ou les profil(s) qui détermine (nt), dans la position atteinte, l'inclinaison de l'assise.In fact, the positioning of the follower lugs on the frame, the orientation of the eccentric cams when they are fixed to the rotating shaft and the design of the profiles are provided in such a way that said lugs can be guided between the two desired angular positions for the seat. The profiles are then traced in such a way that the weight of the user seated on the seat exerts an action reinforcing the lug/stop support in the profile(s) which determines, in the position reached, the inclination of the seat.

En pratique, selon l'invention, au moins un premier profil de chaque came comporte au moins une butée de maintien en la première position angulaire et au moins un second profil comporte au moins une butée de maintien dans la seconde position angulaire. Dans l'hypothèse où il n'y a que deux ergots et que deux profils en périphérie de la came disque, un des profils comporte au moins une butée correspondant à l'une des orientations inclinées, l'autre profil comportant au moins une butée d'arrêt en l'autre orientation inclinée de l'assise, chacun des profils pouvant le cas échéant comporter un moyen de maintien en l'autre position inclinée.In practice, according to the invention, at least one first profile of each cam comprises at least one stop for maintaining the first angular position and at least one second profile comprises at least one stop for maintaining in the second angular position. In the hypothesis where there are only two lugs and only two profiles at the periphery of the disk cam, one of the profiles comprises at least one stop corresponding to one of the inclined orientations, the other profile comprising at least one stop stopping in the other inclined orientation of the seat, each of the profiles possibly including a means of maintaining the other inclined position.

Ainsi, selon une possibilité propre à l'invention, au moins un profil de chaque came peut être muni d'une seconde butée en l'autre des positions stables. Plus précisément, dans une configuration où la came disque comporte deux profils, le profil extérieur peut comporter à une première extrémité une butée présentant une surface d'appui exerçant sur un ergot une action d'allure principalement tangentielle et à une seconde extrémité une butée comportant une surface d'appui exerçant sur ledit ergot une action d'allure principalement radiale. Dans ce cas, dans une des positions stables de l'assise, il y a une double action simultanée sur les deux ergots dans les deux profils extérieur et intérieur, qui renforce le maintien en position inclinée stable dans une des deux positions d'inclinaison possibles.Thus, according to a possibility specific to the invention, at least one profile of each cam can be provided with a second stop in the other stable positions. More precisely, in a configuration where the disk cam has two profiles, the external profile can comprise at a first end a stop having a bearing surface exerting on a lug an action of mainly tangential and at a second end a stop comprising a bearing surface exerting on said lug a mainly radial action. In this case, in one of the stable positions of the seat, there is a double simultaneous action on the two lugs in the two exterior and interior profiles, which reinforces the maintenance in a stable inclined position in one of the two possible inclination positions .

Par ailleurs, selon une configuration possible de l'invention, les moyens de commande manuels consistent en une manette fixée à l'une des extrémités d'un arbre rotatif à section polygonale équipé des cames disques à excentrique. Le positionnement des cames sur l'arbre rotatif à section polygonal se trouve en l'occurrence facilité par les repères que constituent les faces du cylindre à section polygonale, qui peut tourner librement dans le cadre servant de socle à l'assise matelassée.Furthermore, according to a possible configuration of the invention, the manual control means consist of a lever fixed to one of the ends of a rotating shaft with a polygonal section equipped with eccentric disc cams. The positioning of the cams on the rotating shaft with a polygonal section is facilitated in this case by the marks which constitute the faces of the cylinder with a polygonal section, which can rotate freely in the frame serving as a base for the padded seat.

L'invention concerne également un siège muni d'un système de réglage de l'inclinaison de l'assise présentant les caractéristiques ci-dessus.The invention also relates to a seat provided with a seat inclination adjustment system having the above characteristics.

En pratique, lorsque les cames sont actionnées en rotation, elles font monter/descendre la barre transversale du cadre socle de l'assise disposée la plus à l'arrière, c'est-à-dire la plus proche du dossier du siège, par rapport à la barre avant, qui sert d'axe de rotation du cadre.In practice, when the cams are rotated, they raise/lower the crossbar of the base frame of the seat located furthest to the rear, that is to say closest to the seat back, by in relation to the front bar, which serves as the axis of rotation of the frame.

La présente invention va maintenant être décrite en détail, en référence aux figures annexées, pour lesquelles :

  • la figure 1 est une vue de gauche du cadre de l'assise sur son support, en position initiale légèrement inclinée vers l'arrière par rapport à l'horizontale ;
  • la figure 2 représente une vue de gauche similaire, mais en position finale basculée vers l'avant de l'ordre de trois degrés ;
  • la figure 3 est une vue en perspective de droite de la position selon la figure 1, vue dans laquelle la came disque utilisée dans le dispositif de l'invention est particulièrement visible ;
  • la figure 4 montre en vue perspective le cadre sur lequel est fixée l'assise matelassée ;
  • la figure 5 illustre son articulation sur le support auquel est solidarisé le piètement du siège (non représenté) ; et
  • les figures 6 et 7 représentent une vue en élévation d'une came dans ses deux positionnements par rapport aux ergots suiveurs dépassant du cadre supportant l'assise.
The present invention will now be described in detail, with reference to the appended figures, for which:
  • there figure 1 is a left view of the seat frame on its support, in the initial position slightly inclined backwards relative to the horizontal;
  • there figure 2 represents a similar left view, but in the final position tilted forward by around three degrees;
  • there Figure 3 is a right perspective view of the position according to the figure 1 , view in which the disk cam used in the device of the invention is particularly visible;
  • there Figure 4 shows in perspective view the frame on which the padded seat is fixed;
  • there figure 5 illustrates its articulation on the support to which the base of the seat is secured (not shown); And
  • THE figures 6 and 7 represent an elevation view of a cam in its two positions relative to the follower lugs protruding from the frame supporting the seat.

En référence aux différentes figures, le support (1), qui est relié en sa partie inférieure au pied du siège (non représenté), est articulé en sa partie supérieure à un cadre (20) (voir en particulier en figure 4) comportant principalement deux cornières (2, 2') prévues pour être fixées à l'assise (non représentée) et deux arbres transversaux (3, 3') dont l'un (3) constitue de fait l'axe de rotation du cadre (20) par rapport au support (1). Deux cames (4, 4') disques à excentrique sont par ailleurs solidarisées à un arbre (5) à section polygonale disposé au voisinage de la barre (3'). Ces cames (4, 4'), comme cela apparaît plus particulièrement en les figures 6 et 7, comportent deux profils respectivement extérieur (6) et intérieur (7) qui seront décrits plus en détail dans la suite et interagissent avec des ergots suiveurs (10, 11) dépassant des ailes verticales des cornières (2, 2') auxquelles ils sont fixés.With reference to the different figures, the support (1), which is connected in its lower part to the foot of the seat (not shown), is articulated in its upper part to a frame (20) (see in particular in Figure 4 ) mainly comprising two angles (2, 2') intended to be fixed to the seat (not shown) and two transverse shafts (3, 3') one of which (3) actually constitutes the axis of rotation of the frame (20) relative to the support (1). Two eccentric disc cams (4, 4') are also secured to a shaft (5) with a polygonal section arranged in the vicinity of the bar (3'). These cams (4, 4'), as appears more particularly in them figures 6 and 7 , have two profiles respectively exterior (6) and interior (7) which will be described in more detail below and interact with follower lugs (10, 11) protruding from the vertical wings of the angles (2, 2') to which they are fixed.

Il est à noter que les divers composants du mécanisme de siège apparaissant sur ces figures qui ne sont pas liés à l'invention ne sont pas décrits dans ce qui suit, dès lors qu'ils n'ont pas d'incidence sur le fonctionnement du dispositif de réglage de l'inclinaison de l'assise dudit siège.It should be noted that the various components of the seat mechanism appearing in these figures which are not linked to the invention are not described in the following, since they have no impact on the operation of the device for adjusting the inclination of the seat of said seat.

Une manette (9) de commande des déplacements des cames (4, 4') est solidarisée à l'arbre (5), lequel est libre en rotation par rapport aux cornières (2, 2') du cadre (20) et par conséquent apte à entraîner en rotation les deux cames disques (4, 4'). Chaque came (4, 4') est en pratique un excentrique fixé à l'arbre (5) via un orifice (40) décentré présentant une section polygonale correspondant à la section de l'arbre (5) organisant un blocage en rotation de l'un par rapport à l'autre. Les ergots (10, 11) dépassent latéralement des cornières, au voisinage de l'arbre transversal (3') et font donc office de suiveurs guidés dans les profils (6, 7) précités. La manette de commande (9) permet à l'utilisateur d'imprimer manuellement une rotation dans un sens ou dans l'autre à l'arbre (5), mouvement qui se répercute aux cames (4, 4').A lever (9) for controlling the movements of the cams (4, 4') is secured to the shaft (5), which is free to rotate relative to the angles (2, 2') of the frame (20) and therefore capable of rotating the two disk cams (4, 4'). Each cam (4, 4') is in practice an eccentric fixed to the shaft (5) via an off-center orifice (40) having a polygonal section corresponding to the section of the shaft (5) organizing a rotational lock of the 'one in relation to the other. The lugs (10, 11) protrude laterally from the angles, in the vicinity of the transverse shaft (3') and therefore act as guided followers in the aforementioned profiles (6, 7). The control lever (9) allows the user to manually rotate the shaft (5) in one direction or the other, a movement which is reflected in the cams (4, 4').

Dans la position dite initiale du cadre (20), telle qu'elle apparaît notamment en figure 1, et qui correspond à la configuration de la came et des ergots (10, 11) de la figure 6, lesdits ergots (10 et 11) sont disposés de telle sorte qu'un seul des ergots (10) est en appui dans une butée d'extrémité (61) du profil extérieur (6), dont la forme épouse celle de l'ergot (10). L'action est exercée dans une direction tangentielle. Il est à noter que l'ergot (11), qui se déplace et est guidé dans l'autre profil de la came (4, 4'), le profil intérieur (7), n'est pas en butée contre l'extrémité (72) dudit profil intérieur (7).In the so-called initial position of the frame (20), as it appears in particular in figure 1 , and which corresponds to the configuration of the cam and the lugs (10, 11) of the Figure 6 , said lugs (10 and 11) are arranged in such a way that only one of the lugs (10) rests in an end stop (61) of the external profile (6), the shape matches that of the lug (10). The action is exerted in a tangential direction. It should be noted that the lug (11), which moves and is guided in the other profile of the cam (4, 4'), the interior profile (7), does not abut against the end (72) of said interior profile (7).

Dans la position surélevée du cadre (20) apparaissant en figure 2, qui correspond au positionnement relatif ergots (10, 11) / came (4) de la figure 7, l'ergot (11) est disposé en appui contre une butée d'extrémité (71) du profil intérieur (7), pratiquement à l'opposé de son emplacement relativement au dit profil (7) dans la configuration de la figure 1. L'appui est également exercé dans une direction tangentielle. Dans le profil extérieur (6), l'ergot (10) est alors placé dans une autre forme de butée (62), qui exerce une action de type radiale contrairement aux butées (61, 71) décrites jusqu'ici. Le fond de cette butée (62), qui est située au voisinage de l'autre extrémité du profil (6), présente une forme qui épouse l'ergot (10) mais qui s'ouvre dans une direction radiale, alors que les butées précédentes (61, 71), qui exercent une action dont on a vu qu'elle est plutôt tangentielle relativement au mouvement de rotation de ces cames (4, 4'), sont alors tracées selon une orientation d'allure normale à la tangente.In the raised position of the frame (20) appearing in figure 2 , which corresponds to the relative positioning of lugs (10, 11) / cam (4) of the Figure 7 , the lug (11) is arranged to rest against an end stop (71) of the interior profile (7), practically opposite its location relative to said profile (7) in the configuration of the figure 1 . The support is also exerted in a tangential direction. In the external profile (6), the lug (10) is then placed in another form of stop (62), which exerts a radial type action unlike the stops (61, 71) described so far. The bottom of this stop (62), which is located in the vicinity of the other end of the profile (6), has a shape which matches the lug (10) but which opens in a radial direction, while the stops previous ones (61, 71), which exert an action which we have seen is rather tangential relative to the rotational movement of these cams (4, 4'), are then traced in an orientation normal to the tangent.

Le passage de la position de l'assise du siège représentée en figure 1 à la position qui est illustrée en figure 2 implique le déplacement relatif ergots (10, 11) / cames (4, 4') de la configuration montrée en figure 6 à celle de la figure 7. La position de l'axe de rotation de l'arbre d'entraînement (5) par rapport au corps des cames (4, 4'), matérialisée par l'orifice (40), valide bien un fonctionnement de la came (4) en excentrique. Les profils (6) et (7) sont situés et dessinés de telle sorte que la partie du cadre (20) située à l'opposé de l'arbre de pivotement (3) remonte lorsqu'on passe de la configuration de la figure 1 / figure 6 à celle de la figure 2 / figure 7, c'est-à-dire lorsque l'utilisateur du siège déplace la manette de commande (9) visible aux figures 1 et 2 de la position montrée en figure 1 à celle de la figure 2.The change from the position of the seat cushion shown in figure 1 at the position which is illustrated in figure 2 involves the relative movement of lugs (10, 11) / cams (4, 4') of the configuration shown in Figure 6 to that of the Figure 7 . The position of the axis of rotation of the drive shaft (5) relative to the body of the cams (4, 4'), materialized by the orifice (40), validates operation of the cam (4) eccentric. THE profiles (6) and (7) are located and designed in such a way that the part of the frame (20) located opposite the pivot shaft (3) rises when changing from the configuration of the figure 1 / Figure 6 to that of the figure 2 / Figure 7 , that is to say when the user of the seat moves the control lever (9) visible on the figures 1 and 2 from the position shown in figure 1 to that of the figure 2 .

L'arrière du cadre (2) de l'assise, relié à la barre (3'), monte ou descend par conséquent selon le sens de la rotation imprimée à la manette (9), aboutissant respectivement à une position de l'assise légèrement inclinée vers l'avant ou légèrement inclinée vers l'arrière. Les profils (6, 7) sont par ailleurs tracés de telle sorte qu'en butée, dans les deux positions stables de l'assise, le poids de l'utilisateur sur ladite assise conforte l'appui en butée, ce qui renforce la stabilité de l'assise dans ses deux positions de repos. Ainsi, dans la position initiale des figures 1 et 6, l'ergot (10) en appui contre la butée (61) est légèrement redescendu par rapport au maximum supérieur de la courbe du profil (6), et les incidences pondérales sur le système de l'utilisateur assis ont pour conséquence que ledit ergot (10) exerce une action de direction verticale et vers le bas, et ne peut donc pas revenir en arrière sur le trajet du profil (6).The rear of the frame (2) of the seat, connected to the bar (3'), therefore rises or falls according to the direction of rotation imparted to the lever (9), resulting respectively in a position of the seat slightly tilted forward or slightly tilted back. The profiles (6, 7) are also designed in such a way that at abutment, in the two stable positions of the seat, the weight of the user on said seat reinforces the support at abutment, which reinforces stability. of the seat in its two resting positions. Thus, in the initial position of the figures 1 And 6 , the lug (10) resting against the stop (61) has slightly descended relative to the upper maximum of the curve of the profile (6), and the weight impacts on the system of the seated user have the consequence that said lug (10) exerts a vertical and downward direction action, and therefore cannot go back along the path of the profile (6).

De même, dans la position basculée vers l'avant des figures 2 et 7, l'ergot (11) en appui contre la butée (71), est situé à un emplacement qui se trouve au-delà d'un maximum de la courbe du profil intérieur (7) et ne peut donc pas revenir en arrière, sachant que là encore, le poids de l'utilisateur se traduit par l'exercice, par l'ergot (11), d'une force de direction horizontale vers le bas sur la butée (71). En même temps, l'ergot (10) est en appui au fond de la butée (62) « radiale », sur lequel il exerce une force de même nature. Il en résulte que les deux positions possibles de l'assise sont particulièrement stables.Likewise, in the tilted forward position of the figures 2 And 7 , the lug (11) resting against the stop (71), is located at a location which is beyond a maximum of the curve of the interior profile (7) and therefore cannot go back, knowing that here again, the weight of the user results in the exercise, by the lug (11), of a horizontal direction force towards the down on the stop (71). At the same time, the lug (10) rests against the bottom of the “radial” stop (62), on which it exerts a force of the same nature. As a result, the two possible seat positions are particularly stable.

Les exemples ci-dessus ne peuvent pas être considérés comme exhaustifs de l'invention, qui englobe au contraire des modifications de forme, notamment au niveau des profils (6, 7) de la came (4) ou de l'arbre d'entraînement (7) à section polygonale, qui sont strictement équivalentes du point de vue fonctionnel, notamment si les butées des profils (6, 7), qui peuvent elles-mêmes présenter des formes différentes, présentent les caractéristiques techniques soulignées auparavant.The above examples cannot be considered exhaustive of the invention, which on the contrary includes modifications of shape, in particular at the level of the profiles (6, 7) of the cam (4) or of the drive shaft (7) with a polygonal section, which are strictly equivalent from the functional point of view, in particular if the stops of the profiles (6, 7), which can themselves have different shapes, have the technical characteristics highlighted above.
