Description

La présente invention se rapporte à un ski muni d'un dispositif d'amortissement, tel qu'un ski alpin, un ski de fond, un monoski ou un surf pour neige. Elle est relative plus particulièrement à un perfectionnement de ce type de dispositif.The present invention relates to a ski provided with a damping device, such as an alpine ski, a cross-country ski, a monoski or a snowboard. It relates more particularly to an improvement of this type of device.

Il est connu de réaliser le corps du ski grâce à une structure plus ou moins souple.It is known to make the ski body thanks to a more or less flexible structure.

On connaît déjà différents types de ski et il en existe de très nombreuses variantes. Ceux-ci sont constitués par une poutre de forme allongée dont l'extrémité avant est courbée vers le haut pour constituer une spatule, l'extrémité arrière l'étant aussi plus légèrement pour constituer le talon.We already know different types of ski and there are many variations. These consist of an elongated beam whose front end is curved upwards to form a spatula, the rear end also being more slightly to form the heel.

Les skis actuels ont généralement une structure composite dans laquelle sont combinés différents matériaux de manière que chacun d'eux intervienne de façon optimale, compte-tenu de la distribution des contraintes mécaniques lors de l'utilisation du ski. Ainsi, la structure comprend généralement des éléments de protection périphériques, des éléments internes de résistance pour résister aux contraintes de flexion et de torsion, et un noyau. Ces éléments sont assemblés par collage ou par injection, l'assemblage s'effectuant généralement à chaud dans un moule présentant la forme définitive du ski, avec une partie avant fortement relevée en spatule, une partie arrière légèrement relevée en talon, une partie centrale cambrée.Current skis generally have a composite structure in which different materials are combined so that each of them intervenes optimally, taking into account the distribution of mechanical stresses when using the ski. Thus, the structure generally comprises peripheral protection elements, internal resistance elements to resist the flexural and torsional stresses, and a core. These elements are assembled by gluing or by injection, the assembly generally being carried out hot in a mold having the final shape of the ski, with a front part strongly raised in a tip, a rear part slightly raised in the heel, a central arched part. .

Malgré le souci des constructeurs de fabriquer des skis de bonne qualité, ceux-ci n'ont pas, à ce jour trouvé un ski de haute performance satisfaisant dans toutes les conditions d'utilisation.Despite the manufacturers' concern to manufacture good quality skis, they have not, to date found a high performance ski satisfactory in all conditions of use.

Les skis actuels présentent un certain nombre d'inconvénients et en particulier, celui du mauvais comportement lors des oscillations dues aux vibrations ou aux flexions du ski. En effet, les vibrations persistantes provoquent une perte d'adhérence et donc, une mauvaise conduite du ski. Il est donc très important d'amortir les vibrations, ainsi il a déjà été proposé des solutions. Notons par exemple les solutions proposées dans les demandes de brevet français 2 503 569 et 2 575 393. Mais ces dispositifs d'amortissement n'ont en fait que des effets tout à fait mineurs et imperceptibles pour le skieur.Current skis have a certain number of drawbacks and in particular that of poor behavior during oscillations due to vibrations or flexing of the ski. Indeed, the persistent vibrations cause a loss of grip and therefore, poor skiing. It is therefore very important to dampen vibrations, so solutions have already been proposed. Let us note for example the solutions proposed in the French patent applications 2 503 569 and 2 575 393. But these damping devices have in fact only completely minor and imperceptible effects for the skier.

Le brevet français FR 1 115 843 concerne un ski muni d'un dispositif destiné à réduire les déformations en torsion et en flexion de la spatule et qui comprend une barre longitudinale de torsion dont l'extrémité du côté spatule est coudée et qui est fixée rigidement au ski à son extrémité arrière à proximité de la mâchoire. Cette barre travaille à la fois à la torsion en neutralisant la tendance au fléchissement torsionnel de la spatule, et en flexion pendant les vibrations de la spatule par effet de frottement qui s'oppose au déplacement glissant de la barre dans un ancrage avant. Cependant, le frottement s'exerce sur une simple ligne génératrice formée par le contact de deux cylindres sans interposition d'une couche en matériau de frottement spécifique.French patent FR 1,115,843 relates to a ski provided with a device intended to reduce torsional and bending deformations of the spatula and which comprises a longitudinal torsion bar whose end of the spatula side is bent and which is rigidly fixed ski at its rear end near the jaw. This bar works at the same time in torsion by neutralizing the tendency to torsional bending of the spatula, and in bending during the vibrations of the spatula by friction effect which opposes the sliding movement of the bar in an anchorage before. However, friction is exerted on a simple generating line formed by the contact of two cylinders without the interposition of a layer of specific friction material.

La présente invention veut remédier aux différents inconvénients évoqués précédemment et propose une solution particulièrement simple, efficace et fiable aux problèmes d'amortissement des vibrations.The present invention seeks to remedy the various drawbacks mentioned above and proposes a particularly simple, effective and reliable solution to the problems of damping vibrations.

A cet effet, le ski muni d'un dispositif d'amortissement destiné à amortir les vibrations comprend au moins un élément allongé de flexion muni d'une première partie reliée fixement au ski, et d'une deuxième partie espacée longitudinalement de la première partie, et reliée au ski de façon mobile longitudinalement, caractérisé en ce qu'il comprend au moins une couche de frottement présentant une surface de frottement en matériau à coefficient de frottement sec élevé qui exerce un freinage des déplacements longitudinaux relatifs de ladite deuxième partie par rapport au ski, ladite deuxième partie étant située à l'une au moins des extrémités de l'élément allongé et en ce que le dispositif comprend aussi un organe d'appui qui exerce un pincement de ladite couche de frottement avec ladite deuxième partie pour assurer ledit freinage.To this end, the ski provided with a damping device intended to damp the vibrations comprises at least one elongated bending element provided with a first part fixedly connected to the ski, and with a second part spaced longitudinally from the first part. , and connected to the ski movably longitudinally, characterized in that it comprises at least one friction layer having a friction surface made of a material with a high dry friction coefficient which exerts a braking on the relative longitudinal displacements of said second part relative to in skiing, said second part being located at at least one of the ends of the elongated element and in that the device also comprises a support member which exerts a pinching of said friction layer with said second part to ensure said braking.

La couche de frottement peut être soit collée sur le ski, ou encore collée sur l'organe d'appui.The friction layer can either be bonded to the ski, or bonded to the support member.

Selon un mode de réalisation, l'organe d'appui est une pièce fixe fixée au ski.According to one embodiment, the support member is a fixed part fixed to the ski.

Selon d'autres modes de réalisation, l'organe d'appui est constitué par la plaque de base de la fixation destinée à retenir la chaussure de ski, ou une pièce mobile sur laquelle s'appuie la chaussure de ski.According to other embodiments, the support member is constituted by the base plate of the binding intended to retain the ski boot, or a movable part on which the ski boot rests.

L'élément allongé de flexion est une lame métallique, en aluminium ou en acier, ou en matériau composite. Elle est de section transversale rectangulaire mais peut aussi être constituée par une tige de section circulaire.The elongated bending element is a metal blade, made of aluminum or steel, or a composite material. It is of rectangular cross section but can also be constituted by a rod of circular section.

Le dispositif d'amortissement peut être soit en dehors de la structure, soit dans la structure du ski.The damping device can be either outside the structure or in the structure of the ski.

D'autres caractéristiques et avantages de l'invention se dégageront de la description qui va suivre en regard des dessins annexés qui ne sont donnés qu'à titre d'exemples non limitatifs.Other characteristics and advantages of the invention will emerge from the description which follows with reference to the appended drawings which are given only by way of nonlimiting examples.

Le ski (1) comprenant le dispositif est constitué par une poutre allongée (100) ayant se propre distribution d'épaisseur, de largeur et donc sa propre raideur. Il comprend une partie centrale (2) appelée aussi zone de montage des fixations (3, 4) destinées à retenir la chaussure sur le ski, la fixation avant (3) étant communément appelée butée, tandis que la fixation arrière (4) est appelée généralement talonnière. L'extrémité avant (5) du ski (1) est relevée pour former la spatule (6), tandis que l'extrémité arrière (7) l'est aussi pour former le talon (8) du ski. La poutre comprend par ailleurs une surface inférieure de glissement (9) et une surtace supérieure (10). Notons que le contact de la surface inférieure (9) avec la neige se fait entre le point de contact avant (11) et le point de contact arrière (12) correspondant aux endroits où ladite surface inférieure commence à se relever.The ski (1) comprising the device consists of an elongated beam (100) having its own distribution of thickness, of width and therefore its own stiffness. It comprises a central part (2) also called a mounting area for the bindings (3, 4) intended to retain the boot on the ski, the front binding (3) being commonly called a stop, while the rear binding (4) is called usually heel. The front end (5) of the ski (1) is raised to form the tip (6), while the rear end (7) is also raised to form the heel (8) of the ski. The beam further comprises a lower sliding surface (9) and an upper surface (10). Note that the contact of the lower surface (9) with the snow takes place between the front contact point (11) and the rear contact point (12) corresponding to the places where said lower surface begins to rise.

Les figures 1 à 6 représentent un premier mode de réalisation selon lequel le dispositif d'amortissement selon l'invention est constitué par une lame de flexion (13) disposée à l'avant sur la surface supérieure (10) du ski (1). Selon l'invention, ladite lame de flexion est fixée au ski par une première partie constituée par l'extrémité arrière (131) de la lame, tandis qu'elle lui est reliée par une deuxième partie, par des moyens de frottement (14). La fixation de la première partie (131) de la lame sur le ski est une liaison fixe, rigide, réalisée par exemple par des vis, par collage ou par soudage. Selon ce mode de réalisation, la deuxième partie est constituée par l'extrémité avant (130) de la lame de flexion (13) qui est mobile longitudinalement par rapport au ski, et lui est relié par des moyens de frottement (14), qui sont constitués par deux couches (140, 141) de matériau à coefficient de frottement sec, élevé et un étrier de retenue et d'appui (142). Le matériau de frottement sec, élevé peut être constitué par exemple par une couche de caoutchouc thermoplastique ou du matériau viscoélastique. Ainsi, une première couche (140) de caoutchouc est collée sur la surface supérieure (10) du ski, tandis qu'une deuxième couche (141) est collée sous la paroi centrale (143) de l'étrier de retenue qui a la forme d'un Ω (oméga) et qui est fixé au ski par des vis (15). L'extrémité avant (130) de la lame de flexion peut ainsi se déplacer selon F1 et F2 entre la première couche et la deuxième couche de caoutchouc. Pour qu'il y ait dissipation de l'énergie des mouvements longitudinaux selon F1 et F2 de l'extrémité (130) de la lame, l'étrier maintient une pression et pince la lame entre les deux couches. A cet effet, la hauteur (h) du logement inférieur (144) de l'étrier est légèrement inférieure à la somme des épaisseurs de la lame et des deux couches quand celles-ci sont au repos, non pincées par l'étrier.Figures 1 to 6 show a first embodiment according to which the damping device according to the invention consists of a bending blade (13) disposed at the front on the upper surface (10) of the ski (1). According to the invention, said flexion blade is fixed to the ski by a first part constituted by the rear end (131) of the blade, while it is connected to it by a second part, by friction means (14) . The fixing of the first part (131) of the blade on the ski is a fixed, rigid connection, produced for example by screws, by gluing or by welding. According to this embodiment, the second part is constituted by the front end (130) of the flexion blade (13) which is movable longitudinally relative to the ski, and is connected to it by friction means (14), which consist of two layers (140, 141) of material with a high, dry coefficient of friction and a retaining and supporting stirrup (142). The dry, high friction material may consist, for example, of a layer of thermoplastic rubber or of viscoelastic material. So, a first layer (140) of rubber is bonded to the upper surface (10) of the ski, while a second layer (141) is bonded under the central wall (143) of the retaining clip which has the shape of an Ω (omega) and which is fixed to the ski by screws (15). The front end (130) of the bending blade can thus move along F1 and F2 between the first layer and the second layer of rubber. So that there is dissipation of the energy of the longitudinal movements along F1 and F2 of the end (130) of the blade, the stirrup maintains a pressure and clamps the blade between the two layers. For this purpose, the height (h) of the lower housing (144) of the stirrup is slightly less than the sum of the thicknesses of the blade and of the two layers when these are at rest, not pinched by the stirrup.

Bien entendu, l'intensité ou la force de serrage de la lame de flexion entre les deux couches de frottement peut être réglable en fonction de l'amortissement que l'on veut obtenir.Of course, the intensity or the clamping force of the bending blade between the two friction layers can be adjustable as a function of the damping which it is desired to obtain.

La figure 7 est une vue similaire à la figure 3, représentant un mode de réalisation des moyens de réglage de la force de serrage, et donc de l'intensité du frottement. Selon cette variante, l'étrier (142) n'est pas en appui sur la surface supérieure (10) du ski (100), mais en appui sur une couche intermédiaire (140i) élastique. Ainsi, la valeur du serrage des vis (14) définit la force du serrage de la lame (13) entre les deux couches (140, 141) par variation de l'épaisseur (e4).Figure 7 is a view similar to Figure 3, showing an embodiment of the means for adjusting the clamping force, and therefore the intensity of friction. According to this variant, the stirrup (142) is not supported on the upper surface (10) of the ski (100), but supported on an elastic intermediate layer (140i). Thus, the value of the tightening of the screws (14) defines the force of the tightening of the blade (13) between the two layers (140, 141) by variation of the thickness (e4).

Les figures 5, 5a, 6 et 6a représentent schématiquement le fonctionnement de l'amortissement. La figure 5 montre le ski à l'état de repos, et la figure 6, en cours de flexion. Au cours de la flexion, on constate qu'il y a déplacement relatif vers l'avant de l'extrémité avant (130) de la lame par rapport aux moyens de frottement (14). Selon la représentation schématique, l'extrémité avant s'est déplacée vers l'avant selon F1 sur une distance (d) et ce déplacement a été freiné par les couches de frottement (140, 141).Figures 5, 5a, 6 and 6a schematically show the operation of depreciation. Figure 5 shows the ski in the rest state, and Figure 6, during bending. During bending, it is found that there is relative movement towards the front of the front end (130) of the blade relative to the friction means (14). According to the schematic representation, the front end has moved forward along F1 over a distance (d) and this movement has been slowed down by the friction layers (140, 141).

Il va de soi que la lame de flexion peut être plus ou moins longue et par exemple être comme représentée à la figure 8. Selon cette variante, la lame (13) passe librement sous la plaque de base (17) de la butée (3) qui comprend un logement inférieur (18) dont les dimensions sont supérieures aux dimensions de la lame pour en permettre le passage et le libre mouvement. La lame étant alors fixée par son extrémité arrière (131) dans la zone centrale (2) comprise entre la fixation avant (3) et la fixation arrière (4).It goes without saying that the bending blade may be longer or shorter and for example be as shown in FIG. 8. According to this variant, the blade (13) passes freely under the base plate (17) of the stop (3 ) which comprises a lower housing (18) whose dimensions are greater than the dimensions of the blade to allow passage and free movement. The blade then being fixed by its rear end (131) in the central zone (2) between the front fixing (3) and the rear fixing (4).

La figure 9 représente un autre mode d'exécution selon lequel l'extrémité avant (130) de la lame est fixée de façon rigide sur le ski, alors que l'extrémité arrière (131) est montée coulissante dans les moyens de frottement (14).FIG. 9 represents another embodiment according to which the front end (130) of the blade is rigidly fixed on the ski, while the rear end (131) is slidably mounted in the friction means (14 ).

Bien entendu, le dispositif d'amortissement selon l'invention tel que celui décrit précédemment, peut être disposé à l'arrière du ski comme cela apparaît aux figures 10 et 11. Ainsi l'extrémité avant (130) de la lame (13) est fixée au ski et s'étend vers l'arrière de telle sorte que son extrémité arrière (131) soit liée au ski de façon mobile longitudinalement par les moyens de frottement (14).Of course, the damping device according to the invention such as that described above, can be arranged at the rear of the ski as it appears in Figures 10 and 11. Thus the front end (130) of the blade (13) is attached to the ski and extends to the rear so that its rear end (131) is connected to the ski movably longitudinally by the friction means (14).

Les moyens de frottement comprennent des moyens de mise en pression nécessaire au frottement. Ces moyens peuvent être constitués par un organe de pression tel que l'étrier décrit précédemment et représenté aux figures 1 à 11, mais aussi par tout autre dispositif ou organe. Ainsi, les moyens de frottement peuvent être disposés sous l'une des fixations, le montage de celles-ci sur le ski assurant la mise en pression nécessaire et constituant ainsi les organes de pression. Les figures 12 et 13 représentent une telle disposition.The friction means comprise means for pressurizing necessary for friction. These means can be constituted by a pressure member such as the caliper described above and shown in Figures 1 to 11, but also by any other device or member. Thus, the friction means can be arranged under one of the bindings, the mounting of these on the ski ensuring the necessary pressurization and thus constituting the pressure members. Figures 12 and 13 show such an arrangement.

Selon cette variante, la lame de flexion est fixée au ski par son extrémité avant (130), tandis que son extrémité arrière (131) est retenue par les moyens de frottement disposés sous la fixation avant (3) par un montage que l'on voit plus précisément à la figure 13. Comme dans les réalisations précédentes, la lame de flexion (13) est pincée entre deux couches de matériau de frottement (140, 141). Ainsi, la couche inférieure (140) collée sur le ski est formée par une pièce ayant un profil en U, tandis que la couche supérieure (141) est collée sous la plaque de base (17) de la butée (3). C'est le serrage plus ou moins important des vis (170) qui assurera un frottement plus ou moins important.According to this variant, the flexion blade is fixed to the ski by its front end (130), while its rear end (131) is retained by the friction means arranged under the front fixing (3) by a mounting which is see more specifically in Figure 13. As in the previous embodiments, the bending blade (13) is clamped between two layers of friction material (140, 141). Thus, the lower layer (140) bonded to the ski is formed by a part having a U-shaped profile, while the upper layer (141) is bonded under the base plate (17) of the stop (3). It is the more or less important tightening of the screws (170) which will ensure a more or less significant friction.

La figure 14 est une vue similaire à la figure 13 montrant une variante selon laquelle le serrage n'est plus fonction de l'intensité de vissage des vis (170), mais seulement des dimensions en épaisseur des différents éléments. Aussi, on a prévu des entretoises latérales (154) en matériau rigide assurant un appui rigide de la plaque de base et une épaisseur définie (E).Figure 14 is a view similar to Figure 13 showing a variant in which the tightening is no longer a function of the intensity of screwing of the screws (170), but only the thickness dimensions of the different elements. Also, lateral spacers (154) are provided in rigid material ensuring rigid support of the base plate and a defined thickness (E).

Notons que la pression de frottement peut être variable et par exemple fonction de la force d'appui de la chaussure de ski (20). Selon ce nouveau mode de réalisation représenté aux figures 15 et 16, la butée (3) comprend une pièce d'appui (21) pour la chaussure qui est montée mobile autour d'un axe transversal (22), sous laquelle est collée l'une des couches de frottement (141), tandis que l'autre couche (140) est collée sur la surface supérieure (10) du ski. L'extrémité arrière (131) de la lame (13) peut ainsi se déplacer longitudinalement entre les deux couches de frottement (140, 141). Ce déplacement étant plus ou moins freiné en fonction de la valeur de l'effort (F) appliqué par la chaussure sur la plaque d'appui (21). Notons que la fixation (3) avec sa plaque d'appui mobile (21) a fait l'objet d'une demande de brevet français n° 82.20852 déposée par la demanderesse.Note that the friction pressure can be variable and for example a function of the bearing force of the ski boot (20). According to this new embodiment shown in Figures 15 and 16, the stop (3) comprises a support piece (21) for the shoe which is movably mounted around a transverse axis (22), under which the one of the friction layers (141), while the other layer (140) is bonded to the upper surface (10) of the ski. The rear end (131) of the blade (13) can thus move longitudinally between the two friction layers (140, 141). This movement being more or less braked depending on the value of the force (F) applied by the shoe on the support plate (21). Note that the fixing (3) with its movable support plate (21) was the subject of a French patent application No. 82.20852 filed by the applicant.

Dans les différentes réalisations proposées aux figures 1 à 16, le dispositif d'amortissement est disposé en-dehors de la structure proprement dite du ski. Mais on ne sortirait bien entendu pas du cadre de l'invention si celui-ci était disposé dans la structure même du ski, tel que cela est représenté de façon schématique à la figure 17.In the various embodiments proposed in FIGS. 1 to 16, the damping device is arranged outside the structure proper of the ski. But of course we would not go outside the scope of the invention if it were arranged in the very structure of the ski, as shown schematically in FIG. 17.

Les skis sont le plus souvent constitués d'un noyau (101) recouvert par une ou plusieurs couches de renfort supérieur (102), voire même inférieur (103). Le dessus du ski étant recouvert généralement par une couche de décors (104), tandis que le dessous comprend une couche de glissement en polyéthylène (105). Ainsi dans la réalisation de la figure 17, le dispositif d'amortissement est encastré dans le ski et une plaque supérieure (106) assure à la fois la pression nécessaire au frottement, et à la fois l'étanchéité dudit dispositif en l'isolant totalement de l'extérieur.The skis most often consist of a core (101) covered by one or more layers of upper reinforcement (102), or even lower (103). The top of the ski is generally covered by a layer of decorations (104), while the bottom comprises a sliding layer of polyethylene (105). Thus in the embodiment of FIG. 17, the damping device is embedded in the ski and an upper plate (106) ensures both the pressure necessary for friction, and both the tightness of said device by completely isolating it from the outside.

Dans la solution proposée précédemment, les couches de frottement sont collées sur le ski et sur la pièce de frottement. Toutefois, il pourrait en être tout autrement, et les interfaces de frottement (140, 141) pourraient être liés à la lame pour frotter sur le ski et/ou sur la pièce de pression (142, 17, 21). De plus, les couches de frottement (140, 141) qui ne s'étendent que sur l'extrémité de la lame, dans les modes de réalisation représentés, pourraient tout aussi bien s'étendre sur une plus grande longueur, voire même sur toute la longueur de ladite lame.In the solution proposed above, the friction layers are bonded to the ski and to the friction part. However, it could be quite different, and the friction interfaces (140, 141) could be linked to the blade for rubbing on the ski and / or on the pressure piece (142, 17, 21). In addition, the friction layers (140, 141) which extend only over the end of the blade, in the embodiments shown, could just as well extend over a greater length, or even over any the length of said blade.

La figure 18 représente une autre variante en vue latérale selon laquelle le dispositif d'amortissement est constitué par une lame (13c) fixée dans sa partie centrale (132) et dont les extrémités avant (131) et arrière (130) sont liées au ski (1) par des moyens de frottement (14).FIG. 18 represents another variant in side view according to which the damping device is constituted by a blade (13c) fixed in its central part (132) and whose front (131) and rear (130) ends are linked to the ski (1) by friction means (14).

La lame de flexion (13, 13a, 13b, 13c) est une lame en acier, en aluminium ou en matériau composite dont la largeur (l1) est comprise entre 10 et 60 millimètres, son épaisseur (e1) comprise entre 1 et 5 millimètres, et sa longueur (L1), comprise entre 200 et 1200 millimètres.The bending blade (13, 13a, 13b, 13c) is a steel, aluminum or composite material blade whose width (l1) is between 10 and 60 millimeters, its thickness (e1) is between 1 and 5 millimeters , and its length (L1), between 200 and 1200 millimeters.

Pour éviter tout déplacement longitudinal des couches de frottement (140, 141), celles-ci peuvent être encastrées au moins partiellement dans leur pièce de support respective, comme cela est représenté à la figure 19 qui est une vue similaire à la figure 4.To avoid any longitudinal displacement of the friction layers (140, 141), these can be embedded at least partially in their respective support piece, as shown in FIG. 19 which is a view similar to FIG. 4.

La figure 20 est une autre vue similaire à la figure 4 montrant un autre mode de réalisation selon lequel la couche de frottement inférieur (140) est collée sur le ski, tandis que la couche supérieure (141) est collée sous la lame pour être en appui sur ladite couche de frottement inférieure.Figure 20 is another view similar to Figure 4 showing another embodiment in which the lower friction layer (140) is glued to the ski, while the upper layer (141) is glued under the blade to be in pressing on said lower friction layer.

Il va de soi que la lame de flexion qui, dans les réalisations proposées, a une section rectangulaire, peut prendre tout type de forme. Elle peut par exemple être constituée par une tige cylindrique.It goes without saying that the bending blade which, in the proposed embodiments, has a rectangular section, can take any type of shape. It can for example be constituted by a cylindrical rod.

Par ailleurs, notons que le matériau constituant les couches de frottement est choisi en fonction des performances d'amortissement à obtenir, et par exemple en fonction du type de ski, ou type d'utilisation.Furthermore, it should be noted that the material constituting the friction layers is chosen as a function of the damping performance to be obtained, and for example as a function of the type of ski, or type of use.

Notons que le dispositif d'amortissement pourrait être recouvert d'une enveloppe extérieure servant à la fois de pièce d'étanchéité et de pièce de décoration. Cette enveloppe extérieure pourrait d'ailleurs servir d'étrier (142) ou de pièce de retenue empêchant le flambage de la lame.It should be noted that the damping device could be covered with an external envelope serving both as a sealing part and as a decoration part. This outer envelope could moreover serve as a stirrup (142) or as a retaining piece preventing the blade from buckling.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés à titre d'exemples, mais elle comprend aussi tous les équivalents techniques ainsi que leurs combinaisons dans le cadre des revendications.Of course, the invention is not limited to the embodiments described and shown by way of examples, but it also includes all the technical equivalents and their combinations within the scope of the claims.
