Description

La présente invention concerne un collant, c'est-à-dire un article d'habillement qui recouvre au moins la partie inférieure du corps, depuis la taille jusqu'au deux chevilles et éventuellement partiellement la partie supérieure du corps. Elle concerne plus particulièrement un collant qui comporte des zones localisées à effet de contention et qui est spécialement conçu pour la pratique d'un sport dans lequel les jambes sont animées de mouvements répétitifs, notamment la course à pied ou le vélo.The present invention relates to a tights, that is to say an article of clothing that covers at least the lower part of the body, from the waist to the two ankles and possibly partially the upper body. More particularly, it relates to a pantyhose which has localized zones with a restraining effect and which is specially designed for practicing a sport in which the legs are animated with repetitive movements, especially running or cycling.

La contention est bien connue dans le domaine médical, s'agissant notamment de chaussettes ou de bas de contention. Il s'agit en l'occurrence d'articles textiles réalisés dans un matériau de base élastique, par exemple à partir de fils d'élasthanne, dont le mode de tricotage permet d'exercer un effet de compression différencié selon des zones de recouvrement, s'agissant de la cheville, du mollet voire de la cuisse. Les chaussettes ou bas de contention sont préconisés lorsqu'il s'agit d'améliorer la circulation sanguine.The contention is well known in the medical field, especially with regard to socks or stockings. This is in the case of textile articles made of an elastic base material, for example from spandex yarns, the knitting mode of which makes it possible to exert a differentiated compression effect according to overlapping zones, the ankle, calf or thigh. Socks or compression stockings are recommended when it comes to improving blood circulation.

Dans le domaine sportif, il est connu de mettre en oeuvre un effet compressif dans la technique dite du « strapping », consistant à entourer une articulation d'une bande élastique en vue de la stabiliser. Par extension, cette technique du « strapping » est également appliquée pour le maintien des masses musculaires, par exemple autour de la cuisse.In the sports field, it is known to implement a compressive effect in the so-called "strapping" technique, consisting of surrounding a joint with an elastic band in order to stabilize it. By extension, this technique of "strapping" is also applied for the maintenance of muscle masses, for example around the thigh.

On a déjà proposé toute sorte d'articles d'habillement recouvrant certaines parties du corps, avec un effet de contention localisée, la compression ne s'exerçant que sur certaines zones précises, cette compression étant susceptible de conférer l'un ou l'autre des avantages apportés par la contention à savoir améliorer la circulation sanguine, le drainage lymphatique, la proprioception, maintenir les masses musculaires et/ou stabiliser les articulations.It has already been proposed all kinds of clothing items covering certain parts of the body, with a localized compression effect, compression being exerted only on certain specific areas, this compression being capable of conferring one or the other the benefits of restraint, namely improving blood circulation, lymphatic drainage, proprioception, maintaining muscle mass and / or stabilizing joints.

De manière générale, ces articles sont constitués d'un support de base sur lequel est rapportée au moins localement une bande de contention. Le support de base présente une élasticité normale qui ne procure pas d'effet de contention. La bande dite de contention présente une élasticité plus faible, ce qui, lors du porter de l'article, procure l'effet compressif localisé qui est recherché. Cette bande de contention peut être formée d'une pièce textile réalisée dans un matériau moins élastique que le support de base et rapportée par exemple par collage ou par couture. Il peut également s'agir d'un traitement localisé du support de base avec un agent d'imprégnation modifiant l'élasticité du support de base dans la zone imprégnée.In general, these articles consist of a base support on which is reported at least locally a compression band. The base support has a normal elasticity that does not provide a restraining effect. The contention band has a lower elasticity, which, when wearing the article, provides the localized compressive effect that is sought. This compression band may be formed of a textile piece made of a less elastic material than the base support and reported for example by gluing or sewing. It may also be a localized treatment of the base support with an impregnating agent modifying the elasticity of the base support in the impregnated zone.

De tels articles sont connus notamment par les documents WO-91/01704 et EP-0.519.135 .Such articles are known in particular by the documents WO-91/01704 and EP-0519135 .

La présente invention concerne plus particulièrement un article d'habillement qui consiste en un collant spécialement conçu pour la pratique d'un sport dans lequel les jambes sont animées de mouvements répétitifs, notamment la course à pied ou le vélo et qui présente un effet de contention localisé, principalement en vue du soutien des masses musculaires et du maintien de l'articulation des genoux.The present invention relates more particularly to an article of clothing which consists of a tights specifically designed for the practice of a sport in which the legs are animated repetitive movements, including running or cycling and which has a restraining effect localized, mainly for the support of the muscular masses and the maintenance of the knee joint.

La course à pied, que ce soit la course de longue ou moyenne distances ou la course en montagne, généralement dénommée raid, se traduit par la répétition des mêmes mouvements des membres inférieurs, les muscles et les articulations travaillant de la même manière à chaque foulée. La qualité première d'un vêtement, spécialement étudié pour la course, est de ne pas être une gêne pour le coureur et surtout de ne pas faire naître de contrainte mécanique susceptible d'être une source complémentaire d'effort et de fatigue. Il en est de même pour la pratique du vélo.Running, whether long or medium distance running or mountain running, commonly referred to as a raid, results in repetition of the same movements of the lower limbs, muscles and joints working in the same way with each stride . The first quality of a garment, specially designed for the race, is not to be an inconvenience for the runner and especially not to give rise to mechanical stress may be a complementary source of effort and fatigue. It's the same for cycling.

Selon le demandeur, l'application à un collant pour de tels sports des techniques préconisées dans les documents WO-91/01704 et EP-0.519.135 pour la confection d'articles à contention localisée conduit nécessairement à un collant ne comportant pas cette qualité première, mais au contraire présentant l'inconvénient de créer une contrainte mécanique source de gêne et de fatigue pour le coureur.According to the applicant, the application to a tights for such sports techniques advocated in the documents WO-91/01704 and EP-0519135 for the manufacture of articles containing localized necessarily leads to a tights not having this quality first, but on the contrary having the disadvantage of creating a mechanical stress source of discomfort and fatigue for the runner.

La présente invention s'applique à pallier cet inconvénient en proposant un collant, à effet de contention localisé, constitué de pièces textiles extensibles, assemblées les unes aux autres, à savoir des premières pièces d'élasticité normale, des secondes pièces à effet de contention et éventuellement des troisièmes pièces à élasticité supérieure. De plus, toutes les premières et secondes pièces ont, dans l'assemblage, sensiblement la même élasticité moyenne dans la direction longitudinale du collant et les secondes pièces ont, dans la direction transversale, une élasticité qui est inférieure au moins de moitié à l'élasticité des premières pièces.The present invention is to overcome this disadvantage by proposing a tacky, localized contention effect, consisting of extensible textile parts, assembled to each other, namely first pieces of normal elasticity, second pieces to contention effect and possibly third pieces with higher elasticity. In addition, all the first and second pieces have, in the assembly, substantially the same average elasticity in the direction longitudinally of the panty and the second pieces have, in the transverse direction, an elasticity which is less than half of the elasticity of the first pieces.

Ainsi, selon les dispositions particulières de la présente invention, le collant a sensiblement la même élasticité sur toute sa hauteur, dans le sens longitudinal, c'est-à-dire dans la direction générale des membres inférieurs ; cette élasticité, dite moyenne, est choisie en sorte de ne pas occasionner de gêne ni de contrainte mécanique lors des mouvements répétitifs des membres inférieurs du sportif. De ce fait, la présence des secondes pièces à effet de contention n'altère en rien l'élasticité du collant dans le sens longitudinal, contrairement à ce qui se passe lorsque les zones de contention sont des bandes rapportées ou obtenues par imprégnation d'un agent de traitement modifiant localement l'élasticité du support de base, comme dans les documents précités.Thus, according to the particular provisions of the present invention, the adhesive has substantially the same elasticity over its entire height, in the longitudinal direction, that is to say in the general direction of the lower limbs; this elasticity, called average, is chosen so as not to cause discomfort or mechanical stress during repetitive movements of the athlete's lower limbs. Therefore, the presence of the second compression parts does not alter the elasticity of the adhesive in the longitudinal direction, unlike what happens when the compression zones are strips or obtained by impregnation of a processing agent locally modifying the elasticity of the base support, as in the aforementioned documents.

La notion d'élasticité moyenne prend en compte les variations normales de propriétés mécaniques dans toute fabrication textile, variations découlant des différences dues notamment aux provenances des matières premières, aux conditions de tissage ou tricotage, aux réglages des métiers.The notion of average elasticity takes into account the normal variations of mechanical properties in any textile manufacture, variations resulting from the differences due in particular to the provenances of the raw materials, to the conditions of weaving or knitting, to the adjustments of the trades.

Les variations, en plus et en moins , par rapport à une valeur moyenne peuvent être de l'ordre de 5 à 10 %, voire parfois plus.The variations, plus and minus, with respect to an average value can be of the order of 5 to 10%, sometimes even more.

Selon la présente invention, l'effet de contention est obtenu uniquement par la différence d'élasticité, dans la direction transversale du collant, au niveau des secondes pièces. De préférence, la différence d'élasticité moyenne, dans le sens transversal, entre les premières et secondes pièces à effet de contention est dans un rapport de 2 à 3.According to the present invention, the compression effect is obtained solely by the difference in elasticity, in the transverse direction of the adhesive, at the level of the second pieces. Preferably, the mean transverse elasticity difference between the first and second compression members is in the ratio of 2 to 3.

Par exemple les élasticités moyennes dans les sens longitudinal des premières et des secondes pièces sont respectivement de 100% et 97%, tandis que leurs élasticités moyennes dans le sens transversal sont respectivement de 130 % et 50 %.For example, the average elasticities in the longitudinal directions of the first and second parts are respectively 100% and 97%, while their average elasticities in the transverse direction are respectively 130% and 50%.

Dans une variante de réalisation, les premières et secondes pièces étant du type tissé avec des fils de chaîne et/ou du type tricoté avec des colonnes de maille, les fils de chaîne et/ou les colonnes de maille, ont dans l'assemblage toute la même direction longitudinale. On comprend que le respect de cette disposition nécessite une confection particulièrement précise, mais c'est à ce prix que peuvent être obtenus les effets escomptés pour le collant de la présente invention.In an alternative embodiment, the first and second pieces being of the woven type with warp yarns and / or of the knitted type with mesh columns, the warp yarns and / or the mesh columns, have in the assembly all the same longitudinal direction. We understand that the respect of this provision requires a particularly precise confection, but it is at this price that can be obtained the desired effects for the tights of the present invention.

De préférence, l'assemblage des pièces est réalisé par des coutures de type flatlock ou surjet, avantageusement en mettant en oeuvre des fils de type mousse et avec des tensions de fils de couture qui sont réglées à des valeurs inférieures à celles des coutures conventionnelles en sorte d'éviter que la présence des coutures crée une hétérogénéité dans les élasticités moyennes, notamment dans le sens longitudinal , des pièces assemblées.Preferably, the assembly of the parts is carried out by seams of the flatlock or suture type, advantageously by using foam-type yarns and with sewing thread tensions which are set at values lower than those of the conventional seams. to avoid that the presence of seams creates a heterogeneity in the average elasticities, especially in the longitudinal direction, of the assembled parts.

Dans une variante préférée, l'assemblage des premières et secondes pièces au niveau du genou est réalisé avec une confection cintrée selon un angle de flexion qui correspond à une position intermédiaire prise par le membre inférieur lors de mouvements répétitifs. S'agissant d'un collant pour la course à pied, cet angle est de 20° à 25°, notamment de l'ordre de 20° pour un collant pour la course en montagne. De plus, dans ce cas, le collant comporte une troisième pièce à élasticité supérieure sur l'arrière du genou. Dans le cas d'un collant pour cycliste, l'angle de flexion est de l'ordre de 30°. Le fait que le collant, dès sa confection, adopte cette configuration moyenne permet de limiter les forces mises en oeuvre lors des mouvements de flexion-extension des membres inférieurs, sachant qu'en position debout, à l'arrêt, il existe déjà au niveau du genou un angle de flexion de l'ordre de 10°. Cette disposition particulière d'une part ne gêne pas l'extension de la jambe et d'autre part limite les plis susceptibles de se former sur l'arrière du genou lors de la flexion.In a preferred embodiment, the assembly of the first and second parts at the knee is made with a bent construction at a bending angle corresponding to an intermediate position taken by the lower limb during repetitive movements. Being a tights for running, this angle is 20 ° to 25 °, especially of the order of 20 ° for a tights for running in the mountains. In addition, in this case, the panty has a third piece with superior elasticity on the back of the knee. In the case of a cycling tights, the bending angle is of the order of 30 °. The fact that the pantyhose, as soon as it is made, adopts this average configuration makes it possible to limit the forces used during the flexion-extension movements of the lower limbs, knowing that when standing, when stationary, it already exists at the knee bending angle of the order of 10 °. This particular arrangement on the one hand does not hinder the extension of the leg and on the other hand limits the folds likely to form on the back of the knee during bending.

La pièce à élasticité supérieure, située éventuellement sur l'arrière du genou, permet d'absorber, lors de l'extension du genou, la différence de dimensionnement due à la confection cintrée, sans occasionner la mise en oeuvre de forces d'allongement supplémentaire.The upper elastic part, possibly located on the back of the knee, allows to absorb, during the extension of the knee, the sizing difference due to the curved construction, without causing the implementation of additional stretching forces .

Cette troisième pièce à élasticité supérieure est, par exemple, un filet textile à mailles. Un tel filet présente une grande perméabilité à l'air, ce qui peut procurer un effet d'aération complémentaire.This third piece with higher elasticity is, for example, a textile mesh net. Such a net has a high permeability to air, which can provide a complementary aeration effect.

Dans une variante de réalisation, au moins une première pièce comporte au moins une fausse couture, créant une ligne d'élasticité plus réduite, disposée, entre deux secondes pièces, en oblique par rapport à la direction longitudinale. Cette fausse couture évite l'écartement éventuel des deux secondes pièces, par rapport à leur positionnement normal qui pourrait intervenir du fait du changement de distribution des volumes dans le collant lors du travail des muscles.In an alternative embodiment, at least one first piece comprises at least one false seam, creating a line of reduced elasticity, arranged between two second pieces obliquely to the longitudinal direction. This false seam avoids the possible spacing of the two second pieces, compared to their normal positioning which could intervene because of the change of distribution of the volumes in the sticky during the work of the muscles.

Dans une variante de réalisation, une seconde pièce à effet de contention est disposée dans la partie du collant qui est destinée à recouvrir, au niveau de la jambe, les muscles jumeaux internes et externes et la partie basse médiale du mollet.In an alternative embodiment, a second compression piece is disposed in the portion of the panty which is intended to cover, at the level of the leg, the inner and outer twin muscles and the medial lower part of the calf.

Dans une variante de réalisation, une seconde pièce à effet de contention est disposée dans la partie du collant destinée à recouvrir, au niveau du mollet, le muscle tibialis anterior.In an alternative embodiment, a second piece of contention effect is disposed in the portion of the adhesive intended to cover, at the level of the calf, the anterior tibialis muscle.

Dans une variante de réalisation, une seconde pièce à effet de contention est disposée dans la partie du collant destinée à recouvrir, autour de l'articulation du genou, les ligaments latéraux internes et externes, la tubérosité tibiale antérieure, le ligament rotulien et toute la partie antérieure de l'articulation du genou.In an alternative embodiment, a second compression piece is disposed in the portion of the tights intended to cover, around the knee joint, the internal and external lateral ligaments, the anterior tibial tuberosity, the patellar ligament and the entire anterior part of the knee joint.

La rotule est de préférence recouverte par une première pièce ou éventuellement une troisième pièce, ladite première ou troisième pièce ayant par exemple une configuration sensiblement circulaire, oblongue ou rectangulaire dont les côtés supérieurs et inférieurs sont une courbure convexe.The ball is preferably covered by a first part or possibly a third part, said first or third part having for example a substantially circular, oblong or rectangular configuration whose upper and lower sides are a convex curvature.

Dans une variante de réalisation, une seconde pièce en forme de V est disposée dans la partie du collant destinée à recouvrir, selon les ailes du V, d'une part, la partie antérieure de l'articulation du genou, au niveau de la base du V, et d'autre part, la face antérieure de la cuisse. La première aile du V recouvre le vaste externe (Vastus lateralis) et le tenseur du fascia lata (Tensor fasciae latae) pour se terminer sur l'épine iliaque antéro-supérieure au niveau de la ceinture du collant. La seconde aile du V recouvre le vaste interne (Vastus medialis) et le groupe musculaire des adducteurs.In an alternative embodiment, a second V-shaped part is disposed in the part of the adhesive intended to cover, according to the wings of the V, on the one hand, the anterior part of the knee joint, at the level of the base. V, and on the other hand, the anterior aspect of the thigh. The first wing of the V covers the outer vastus (Vastus lateralis) and the tensor of the fascia lata (Tensor fasciae latae) to terminate on the anterior superior iliac spine at the waistband of the tights. The second wing of the V covers the vastus medialis (Vastus medialis) and the muscular group of adductors.

Dans une variante de réalisation, une seconde pièce à effet de contention est disposée dans la partie du collant destinée à recouvrir, sur la partie arrière, le groupe musculaire des ischios-jambiers de la partie latérale haute à la partie médiale basse.In an alternative embodiment, a second piece of contention effect is disposed in the portion of the tights intended to cover, on the rear part, the muscular group of the ischiostrures of the upper lateral part to the lower medial part.

Dans une variante de réalisation, une seconde pièce à effet de contention est disposée dans la partie avant du collant, destinée à recouvrir l'abdomen, sous la forme d'une bande transversale dont la partie centrale est plus haute que ses deux parties latérales.In an alternative embodiment, a second compression piece is disposed in the front portion of the tights, intended to cover the abdomen, in the form of a transverse band whose central portion is higher than its two side portions.

Dans une variante de réalisation, une seconde pièce à effet de contention est disposée dans la partie arrière du collant destinée à recouvrir le bas du dos, au dessus des muscles grand fessiers sous la forme d'une bande transversale. De préférence, dans ce cas, une troisième pièce formée d'un filet à mailles ouvertes est disposée au dessus de ladite seconde pièce, au niveau de la taille, dans le but d'obtenir une meilleure évacuation de la sueur.In an alternative embodiment, a second piece of contention effect is disposed in the rear portion of the tights intended to cover the lower back, above the gluteus maximus muscles in the form of a transverse band. Preferably, in this case, a third piece formed of an open mesh is disposed above said second piece, at the waist, in order to obtain better evacuation of sweat.

Dans une variante de réalisation, une troisième pièce à élasticité supérieure est disposée dans la partie du collant destinée à recouvrir la zone d'entrejambe, prenant naissance le long du sillon sous-fessier pour rejoindre la tubérosité fémorale interne.In an alternative embodiment, a third piece of higher elasticity is disposed in the portion of the tights intended to cover the crotch zone, originating along the sub-gluteal sulcus to join the internal femoral tuberosity.

La présente invention sera mieux comprise à la lecture de la description qui va être faite de trois exemples préférés de réalisation de collants, le premier spécialement conçu pour la course à pied de longue et moyenne distances, le deuxième pour la course à pied en montagne ou raid et le troisième pour la pratique du vélo présentant des zones localisées à effet de contention, illustré par le dessin annexé dans lequel :

  • les figures 1 à 3 correspondent au premier exemple en vue de face pour la figure 1, en vue arrière pour la figure 2 et en vue de côté pour la figure 3 ;
  • les figures 4 et 5 correspondent au deuxième exemple en vue de face pour la figure 4 et en vue arrière pour la figure 5 et,
  • les figures 6 à 8 correspondent au troisième exemple en vue de face pour la figure 6, en vue arrière pour la figure 7 et une vue de côté pour la figure 8.
The present invention will be better understood on reading the description which will be made of three preferred embodiments of pantyhose, the first specifically designed for running long and medium distances, the second for running in the mountains or raid and the third for cycling with localized contention zones, illustrated by the accompanying drawing in which:
  • the Figures 1 to 3 match the first example in front view for the figure 1 , in rear view for the figure 2 and in side view for the figure 3 ;
  • the Figures 4 and 5 match the second example in front view for the figure 4 and in rear view for the figure 5 and,
  • the Figures 6 to 8 correspond to the third example in front view for the figure 6 , in rear view for the figure 7 and a side view for the figure 8 .

Le collant de la présente invention est principalement destiné aux sportifs pratiquant un sport au cours duquel les jambes sont animées de mouvements répétitifs, notamment la course de moyenne et longue distances, le raid ou le vélo.The pantyhose of the present invention is primarily intended for athletes practicing a sport in which the legs are animated repetitive movements, including the race of medium and long distances, the raid or the bike.

Il est constitué, au moins dans la portion qui est destinée à recouvrir la partie inférieure du corps, depuis la taille jusqu'au deux chevilles, par l'assemblage de trois types de pièces, selon une technique de couture qui limite ou élimine les risques d'hétérogénéité d'élasticité entre les pièces assemblées, comme expliqué ci-après. Les bords des pièces assemblées sont juxtaposés, sans aucune superposition.It is constituted, at least in the portion that is intended to cover the lower part of the body, from the waist to the two pegs, by assembling three types of parts, according to a seam technique that limits or eliminates the risks heterogeneity of elasticity between the assembled parts, as explained below. The edges of the assembled pieces are juxtaposed, without any superposition.

Les pièces dénommées ci-après premières pièces sont coupées dans un matériau textile élastique, d'élasticité normale. Il s'agit par exemple d'un tricot indémaillable à armure dénommé charmeuse, faisant de l'ordre de 170 g/m2, constitué de fils 80/20 polyamide-élasthanne.The parts referred to hereinafter as the first pieces are cut in an elastic textile material of normal elasticity. This is for example a knit-proof knit armor called charmeuse, making the order of 170 g / m 2 , consisting of 80/20 son polyamide-elastane.

Un tel tricot présente une élasticité moyenne dans le sens longitudinal, selon les colonnes de maille, se traduisant par un allongement élastique de 100% et dans le sens transversal par un allongement élastique de 130%.Such a knit has an average elasticity in the longitudinal direction, according to the mesh columns, resulting in an elastic elongation of 100% and in the transverse direction by an elastic elongation of 130%.

Les pièces dénommées ci-après secondes pièces sont découpées dans un matériau textile élastique dont l'élasticité moyenne dans le sens transversal est nettement inférieure à celle des premières pièces dans un rapport d'au moins de 2 et de préférence dans un rapport de 2 à 3. Ce matériau permet une contention supérieure à 7mmHg.The parts referred to hereinafter as second parts are cut from an elastic textile material whose mean elasticity in the transverse direction is significantly lower than that of the first parts in a ratio of at least 2 and preferably in a ratio of 2 to 3. This material allows a contention higher than 7mmHg.

Dans un exemple de réalisation, il s'agit d'un tricot indémaillable à armure charmeuse , mais inversée, faisant de l'ordre de 240 g/m2, constituée de fils 80/20 polyamide microfibres, élasthanne.In an exemplary embodiment, it is a knit-proof knit charmeuse armor, but inverted, making the order of 240 g / m 2 , consisting of son 80/20 microfiber polyamide, elastane.

Pour la mesure de l'élasticité moyenne, les allongements sont calculés sous une force de 15 N. Dans les exemples précités, les élasticités moyennes, dans le sens longitudinal, des premières et secondes pièces du collant sont quasiment identiques, avec un écart inférieur à 5%, tandis que la différence d'élasticité moyenne entre les premières pièces et les secondes pièces , dans le sens transversal, est dans un rapport de 2,5.For the measurement of the average elasticity, the elongations are calculated under a force of 15 N. In the above examples, the mean elasticities, in the longitudinal direction, of the first and second parts of the adhesive are almost identical, with a difference of less than 5%, while the average elasticity difference between the first pieces and the second pieces, in the transverse direction, is in a ratio of 2.5.

Les pièces, dénommées ci-après troisièmes pièces, sont des pièces dont l'élasticité moyenne est supérieure à celle de la première pièce. Il s'agit notamment d'un filet à mailles relativement ouvertes, permettant d'assurer également un effet d'aération dans les zones qu'il recouvre.The parts, hereinafter referred to as third parts, are parts whose average elasticity is greater than that of the first part. It is in particular a mesh net relatively open, also ensuring a ventilation effect in the areas it covers.

Dans le premier exemple qui est illustré aux figures 1 à 3, le collant 1 pour homme est destiné aux coureurs de moyenne et longue distances. Il est formé par l'assemblage de dix-huit panneaux consistant en huit panneaux [C, C', I, J, K, L, N, N'] ayant la structure des premières pièces à élasticité normale, six seconds panneaux [A, A', B, B', F, H] ayant la structure des secondes pièces à effet de contention, ayant une élasticité transversale plus faible que celle des premières pièces et quatre troisièmes panneaux (D, D', E, G,) ayant la structure de troisièmes pièces, formées d'un filet à maille ouverte. Sur les figures , les premiers panneaux sont représentés sans hachure, les seconds panneaux avec des hachures horizontales et les troisièmes panneaux avec des hachures obliques.In the first example which is illustrated in Figures 1 to 3 , the pantyhose 1 for men is intended for runners of medium and long distances. It is formed by the assembly of eighteen panels consisting of eight panels [C, C ', I, J, K, L, N, N'] having the structure of the first parts with normal elasticity, six second panels [A , A ', B, B', F, H] having the structure of the second compression members, having a lower transverse elasticity than that of the first pieces and four third panels (D, D ', E, G,) having the structure of thirds pieces, formed of an open mesh net. In the figures, the first panels are shown without hatching, the second panels with horizontal hatching and the third panels with oblique hatching.

Cet assemblage est réalisé de telle sorte que toutes les colonnes de maille des premières et secondes pièces assemblées présentent la même direction, correspondant à la direction longitudinale du collant, c'est-à-dire à la direction verticale lorsque le collant est porté par un utilisateur se tenant debout.This assembly is made such that all the mesh columns of the first and second assembled parts have the same direction, corresponding to the longitudinal direction of the adhesive, that is to say to the vertical direction when the adhesive is carried by a user standing.

De plus, cet assemblage est réalisé selon une confection cintrée au niveau de l'articulation de chaque genou selon un angle de flexion dudit genou de l'ordre de 20° à 25°.In addition, this assembly is made according to a bent construction at the joint of each knee at a bending angle of the knee of the order of 20 ° to 25 °.

L'assemblage se fait par couture du type flatlock ou surjet, en utilisant des fils mousses , par exemple texturés, au trameur. Il est souhaitable de régler la tension des fils des machines à coudre à une valeur inférieure à celle couramment utilisée afin de limiter l'effet négatif que pourrait présenter la présence des coutures sur l'homogénéité des élasticités moyennes des pièces assemblées, notamment dans le sens longitudinal.The assembly is done by sewing the flatlock type or suture, using foamed son, for example textured, the framer. It is desirable to adjust the tension of the threads of the sewing machines to a value lower than that currently used in order to limit the negative effect that the presence of the seams may have on the uniformity of the average elasticities of the assembled parts, particularly in the direction longitudinal.

La répartition des différents panneaux dans la confection du collant et les zones qu'ils recouvrent sur le corps du coureur vont être décrites ci-après en référence aux figures 1 à 3.The distribution of the various panels in the manufacture of the tights and the areas they cover on the body of the runner will be described below with reference to Figures 1 to 3 .

Il faut bien noter que le nombre de panneaux mis en oeuvre dans la confection peut différer, notamment s'agissant d'un collant pour homme ou pour femme et que ce qui importe ce n'est pas le nombre de panneaux mais bien la répartition des premières, secondes et troisièmes pièces sur les parties du corps concernées du collant. Dans la suite de la description, il sera fait usage du terme panneau dans la description précise du mode de réalisation illustré aux figures et des termes premières, secondes et troisièmes pièces pour ce qui concerne leur disposition localisée sur les zones du corps.It should be noted that the number of panels used in the clothing industry may differ, particularly in the case of a tights for men or women, and that what matters is not the number of panels but the distribution of the panels. first, second and third pieces on the relevant parts of the body of the pantyhose. In the remainder of the description, use will be made of the term panel in the precise description of the embodiment illustrated in the figures and the terms first, second and third parts as regards their location located on the areas of the body.

Au niveau de la partie inférieure de la jambe, correspondant au mollet, une seconde pièce 2 recouvre les muscles jumeaux interne et externe (Gastrocnemius medialis et Gastrocnemius lateralis) ainsi que la partie basse médiale du mollet. Plus précisément, cette seconde pièce 2 recouvre toute la partie interne du mollet commençant le long du bord interne du tibia (Margo medialis), entre la base de la tubérosité tibiale interne (Condylus medialis) et s'arrêtant au-dessus de la malléole interne (Malleolus medialis) en longeant le bord interne du tibia. Cette seconde pièce se prolonge jusqu'au milieu de la face arrière du mollet, dans le prolongement du tendon d' Achille , pour sa partie basse et recouvre le muscle jumeau latéral pour sa partie haute , en suivant le schéma anatomique décrit par le ventre de ce muscle dans sa partie latérale et basse. Cette seconde pièce 2 est donc dissymétrique puisque, partant d'une ligne horizontale traversant les muscles jumeaux à hauteur de la base de la tubérosité tibiale interne , elle se prolonge jusqu'à la base la du collant 1 pour sa partie médiale alors qu'elle s'arrête sous le muscle jumeau interne pour sa partie latérale , suivant la courbure formée par le ventre de ce muscle pour la partie latérale et basse. Cette seconde pièce 2 fait partie des deux panneaux A, A'.At the level of the lower part of the leg, corresponding to the calf, a second piece 2 covers the inner and outer twin muscles (Gastrocnemius medialis and Gastrocnemius lateralis) as well as the medial lower part of the calf. More precisely, this second piece 2 covers the entire inner part of the calf starting along the internal edge of the tibia (Margo medialis), between the base of the internal tibial tuberosity (Condylus medialis) and stopping above the medial malleolus (Malleolus medialis) along the inner edge of the tibia. This second piece extends to the middle of the back of the calf, in the extension of the Achilles tendon, for its lower part and covers the lateral twin muscle for its upper part, following the anatomical pattern described by the belly of this muscle in its lateral and low part. This second piece 2 is therefore asymmetrical because, starting from a horizontal line crossing the twin muscles at the height of the base of the internal tibial tuberosity, it extends to the base of the glue 1 for its medial part while it stops under the internal twin muscle for its lateral part, following the curvature formed by the belly of this muscle for the lateral and low part. This second piece 2 is part of two panels A, A '.

Une autre seconde pièce 3 recouvre le muscle tibialis anterior. Cette seconde pièce 3 est délimitée par la crête du tibia (Margo anterior) et une ligne verticale passant par la malléole externe et la tête du péroné (Fibula). Cette seconde pièce 3 se prolonge vers le genou. Cette seconde pièce 3 correspond aux panneaux B, B' qui se terminent dans leur partie basse à la base la et 1'a du collant 1 et se prolongent dans leur partie haute jusqu'aux panneaux A, A'.Another second piece 3 covers the anterior tibialis muscle. This second piece 3 is delimited by the crest of the tibia (Margo anterior) and a vertical line passing through the medial malleolus and the head of the fibula (Fibula). This second piece 3 extends towards the knee. This second piece 3 corresponds to the panels B, B 'which end in their lower part at the base la and 1'a sticky 1 and extend in their upper part to the panels A, A'.

Au niveau de la partie du corps correspondant au genou, une seconde pièce 4 recouvre les ligaments latéraux internes (Lig. Collaterale tibiale) et externes (Lig. Collaterale fibulare), la tubérosité tibiale antérieure (Tuberositas tibiae), le soutien rotulien (Lig. patellae) et toute la partie antérieure de l'articulation du genou. Dans l'exemple des figures, cette seconde pièce 4 fait partie des panneaux A, A'.At the level of the part of the body corresponding to the knee, a second piece 4 covers the lateral ligaments (Tibial Collateral ligament) and external ligament (Collateral ligament fibulare), the anterior tibial tuberosity (Tuberositas tibiae), the patellar support (Lig. patellae) and the entire anterior part of the knee joint. In the example of the figures, this second piece 4 is part of the panels A, A '.

La rotule (patella) est recouverte soit par une première pièce 5 , comme représentée à la figure 1, soit éventuellement par une troisième pièce , suivant les conditions climatiques dans lesquelles l'usage du collant est envisagé. Cette première pièce constitue les panneaux C et C'. Elle peut avoir une configuration circulaire, ou oblongue ou rectangulaire avec ses deux côtés supérieur et inférieur ayant une courbure convexe.The patella is covered either by a first piece 5, as shown in FIG. figure 1 , or possibly by a third room, depending on the climatic conditions in which the use of the tights is envisaged. This first piece constitutes the panels C and C '. It can have a circular configuration, or oblong or rectangular with its two upper and lower sides having a convex curvature.

Une troisième pièce 6 recouvre , sur l'arrière du genou, toute la zone poplitée (Fossa poplitea) et se termine dans sa partie supérieure par une ligne horizontale se plaçant environ 5 cm au-dessus de la partie supérieure des tubérosités fémorales internes et externes (Epicondylus medialis et Epicondylus lateralis). Cette troisième pièce 6 correspond aux panneaux D et D'.A third piece 6 covers, on the back of the knee, the entire popliteal area (Fossa poplitea) and ends in its upper part by a horizontal line placed about 5 cm above the upper part of the femoral tuberosities internal and external (Epicondylus medialis and Epicondylus lateralis). This third piece 6 corresponds to panels D and D '.

Au niveau de la partie du corps correspondant à la cuisse, une première pièce 7 recouvre la face antérieure du genou et se prolonge au niveau de la cuisse en formant un V sur la face antérieure de celle-ci. La première aile 7a du V recouvre le vaste externe (Vastus lateralis) et le tenseur du fascia lata (Tensor fasciae latae) pour se terminer sur l'épine iliaque antéro-supérieure (Spina iliaca anterior superior) au niveau de la ceinture, correspondant à la partie supérieure 1b du collant 1. Cette aile 7a recouvre la bande de Maissiat (Tractus iliotibialis) et se termine pour sa partie latérale postérieure par une droite prolongeant le ligament latéral externe du genou, passant par le grand trochanter (Trochanter major) et se prolongeant jusqu'à la partie supérieure 1b.At the part of the body corresponding to the thigh, a first piece 7 covers the anterior face of the knee and extends at the thigh forming a V on the anterior face thereof. The first wing 7a of the V covers the outer vastus (Vastus lateralis) and the tensor of the fascia lata (Tensor fasciae latae) and terminates in the anterior superior iliac spina (Spina iliaca anterior superior) at the waist, corresponding to the upper part 1b of the glue 1. This flange 7a covers the iliotibialis band (Tractus iliotibialis) and terminates for its posterior lateral part by a straight line extending the lateral lateral ligament of the knee, passing through the greater trochanter (Trochanter major) and extending to the upper part 1b.

De cette aile 7a part un prolongement 7b sur la partie arrière de la cuisse, croisant le groupe musculaire des ischios-jambiers , de la partie latérale haute à la partie médiale basse. Dans sa partie supérieure , ce prolongement 7b souligne les muscles fessiers le long du sillon sous-fessier. Il descend, en oblique, du tiers supérieur du fémur vers la tubérosité fémorale interne et recouvre, pour sa partie interne , le groupe musculaire des adducteurs.From this wing 7a extends an extension 7b on the back of the thigh, crossing the muscular group of the hamstrings, from the upper lateral part to the lower medial part. In its upper part, this extension 7b emphasizes the gluteal muscles along the sub-gluteal fold. It descends obliquely from the upper third of the femur to the internal femoral tuberosity and covers, for its internal part, the muscular group of the adductors.

La seconde pièce 7 en forme de V comporte une seconde aile 7c , qui recouvre le vaste interne (Vastus medialis) et qui part en arrière pour rejoindre le prolongement 7b de la première aile 7a au niveau des adducteurs. La liaison entre ce prolongement 7b et la seconde aile 7c est réalisée par l'assemblage sur lui-même du panneau correspondant A ou A' par une couture verticale, passant par la tubérosité fémorale interne (Epicondylus medialis). Le prolongement 7b et la seconde aile 7c se terminent , pour leur limite supérieure, à 2 ou 3 centimètres sous le pli de l'entrejambe, au niveau de la symphyse pubienne (Symphysis pubica).The second V-shaped piece 7 comprises a second wing 7c, which covers the vast internal (Vastus medialis) and which goes back to join the extension 7b of the first wing 7a at the adductors. The connection between this extension 7b and the second flange 7c is achieved by the assembly on itself of the corresponding panel A or A 'by a vertical seam, passing through the internal femoral tuberosity (Epicondylus medialis). The extension 7b and the second wing 7c end, for their upper limit, 2 or 3 centimeters below the fold of the crotch, at the symphysis pubis (Symphysis pubica).

La zone de l'entrejambe est recouverte d'une troisième pièce 8 qui correspond au panneau E.The zone of the crotch is covered with a third piece 8 which corresponds to the panel E.

Au niveau de la zone du corps correspondant au ventre , une seconde pièce 9 recouvre transversalement l'abdomen ; son bord inférieur présente une configuration en V de sorte que la hauteur en son centre 9a est supérieure à la hauteur de chacun de ses côtés. Cette seconde pièce 9 correspond au panneau F dont la partie supérieure correspond au bord supérieure 1b du collant 1.At the level of the area of the body corresponding to the belly, a second part 9 covers the abdomen transversely; its lower edge has a V configuration so that the height at its center 9a is greater than the height of each on its sides. This second piece 9 corresponds to the panel F whose upper part corresponds to the upper edge 1b of the glue 1.

Dans la partie du corps correspondant au dos , une troisième pièce 10 forme la ceinture arrière du collant. Elle correspondant au panneau G.In the body portion corresponding to the back, a third piece 10 forms the back waistband of the pantyhose. It corresponds to the panel G.

Sous cette troisième pièce 10 est prévue une seconde pièce 19 qui recouvre transversalement le bas du dos au-dessus des muscles grand fessiers (Gluteus maximus).Under this third piece 10 is provided a second piece 19 which covers transversely the lower back over the gluteus maximus muscles.

Dans toutes les autres zones du corps non recouvertes comme indiqué ci-dessus par des secondes ou troisièmes pièces, le collant est constitué de premières pièces à savoir : deux premières pièce 11, 12 de part et d'autre de la seconde pièce 3, une première pièce 13 selon la face avant des cuisses et remontant vers l'abdomen, une première pièce 14 recouvrant les muscles grand fessiers, une première pièce 22 sur le côté arrière de la cuisse. Ces différentes premières pièces correspondent respectivement aux panneaux I, I', J, J', K , L, N et N'.In all the other areas of the body not covered as indicated above by second or third parts, the pantyhose consists of first pieces namely: first two pieces 11, 12 on either side of the second piece 3, a first piece 13 according to the front of the thighs and back to the abdomen, a first piece 14 covering the gluteus maximus muscles, a first piece 22 on the back side of the thigh. These different first pieces respectively correspond to panels I, I ', J, J', K, L, N and N '.

Comme cela apparaît sur la figure 1, deux fausses coutures 15, 15', croisent la partie antérieure des deux cuisses. Chaque couture 15 relie la couture 16 entre les panneaux A et K , depuis un point supérieur 17 qui est situé à la base du tenseur du fascia lata jusqu'à un point inférieur 18 au niveau du vaste interne. Cette fausse couture 15 a pour effet de créer une ligne d'élasticité plus réduite , entre ces deux points 17, 18 en sorte d'éviter l'écartement éventuel entre les deux ailes en V du panneau A, par rapport à leur position normale , écartement qui pourrait intervenir du fait du changement de distribution des volumes dans le collant 1 lors du travail des muscles.As it appears on the figure 1 two false seams 15, 15 'intersect the anterior part of the two thighs. Each seam 15 connects the seam 16 between the panels A and K, from an upper point 17 which is located at the base of the tensor of the fascia lata to a lower point 18 at the level of the vast internal. This false seam 15 has the effect of creating a reduced line of elasticity, between these two points 17, 18 so as to avoid the possible spacing between the two wings V of the panel A, relative to their normal position, spacing that could occur due to the change in distribution of volumes in the tights 1 during the work of the muscles.

Dans la description des second et troisième exemples ci-après, il ne sera plus fait mention des panneaux proprement dits, qui sont du ressort du montage du collant lors de sa confection, mais uniquement des premières, secondes et troisièmes pièces, caractéristiques de la présente invention.In the description of the second and third examples below, no mention will be made of the actual panels, which are the responsibility of the mounting of the tights during its manufacture, but only the first, second and third parts, characteristics of the present invention.

Dans le second exemple, qui est illustré aux figures 4 et 5, le collant 30 est destiné aux sportifs qui pratiquent le raid, c'est-à-dire la course à pied en montagne. Il s'agit donc également d'un collant pour la course mais qui présentent néanmoins un certain nombre de différences par rapport au collant du premier exemple.In the second example, which is illustrated in Figures 4 and 5 , the tights 30 is intended for athletes who practice the raid, that is to say running in the mountains. It is therefore also a sticky for the race but that nevertheless have a number of differences compared to the sticky of the first example.

La description qui va suivre s'attache à souligner uniquement ces différences.The description that follows focuses on highlighting only these differences.

S'agissant de la partie inférieure de la jambe, depuis la zone du genou jusqu'à la base du collant, seule diffère la suppression de la seconde pièce 3 qui recouvrait, dans le collant 1 du premier exemple, le muscle tibialis antérieur. Cette seconde pièce 3 peut d'ailleurs être aussi supprimée dans le collant 1 pour la course de moyenne ou longue distance.As regards the lower part of the leg, from the knee zone to the base of the tights, only differs the suppression of the second piece 3 which covered, in the tights 1 of the first example, the anterior tibialis muscle. This second piece 3 can also be removed in the pantyhose 1 for the race of medium or long distance.

Au niveau de la partie du corps correspondant à la cuisse, une seconde pièce 31 recouvre la face antérieure du genou et se prolonge sur la face antérieure de la cuisse en recouvrant le vaste externe (Vastus lateralis) et le tenseur du fascia lata (Tensor fasciae latae) pour se terminer sur l'épine iliaque antéro-supérieure (Spina iliaca anterior superior) au niveau de la ceinture correspondant à la partie supérieure 30a du collant.At the level of the part of the body corresponding to the thigh, a second piece 31 covers the anterior surface of the knee and extends on the anterior aspect of the thigh by covering the vastus externa (Vastus lateralis) and the tensor of the fascia lata (Tensor fasciae). latae) to end on the anterior superior iliac spina (Spina iliaca anterior superior) at the waist corresponding to the upper part 30a of the pantyhose.

Cette seconde pièce 31 recouvre la bandelette de Maissiat (Tractus iliotibialis) et se termine pour sa partie latérale postérieure par une droite prolongeant le ligament latéral externe du genou, passant par le grand trochanter (Trochanger major) et se prolongeant jusqu'à la partie supérieure du collant.This second piece 31 covers the iliotibialis band and terminates for its posterior lateral part by a straight line extending the lateral lateral ligament of the knee, passing through the greater trochanter (Trochanger major) and extending to the upper part. sticky.

Une autre seconde pièce 32 constitue un prolongement de la seconde pièce 31 précitée, sur la face postérieure de la cuisse croisant le groupe musculaire des fessiers, et notamment le muscle grand fessier (Gluteus maximus). Cette seconde pièce 32 prend naissance au niveau du tenseur du fascia lata pour se terminer dans la région sacrée et au niveau de la charnière lombo-sacrée.Another second piece 32 constitutes an extension of the second piece 31 above, on the posterior side of the thigh crossing the muscular group of glutes, and in particular the gluteus maximus muscle. This second piece 32 originates at the level of the tensor of the fascia lata and ends in the sacred region and at the level of the lumbosacral hinge.

Des fausses coutures, non représentées sur les figures 4 et 5, peuvent croiser les parties médiales et latérales du genou dans la seconde pièce correspondante, afin de diminuer localement l'extensibilité du matériau et ainsi augmenter la stabilité articulaire.False seams, not shown on the Figures 4 and 5 , can cross the medial and lateral parts of the knee in the corresponding second part, in order to locally reduce the extensibility of the material and thus increase joint stability.

Au niveau de la zone du corps correspondant au ventre, une seconde pièce 33 recouvre transversalement l'abdomen et s'étend entre les secondes pièces 31 des deux jambes qui se prolongent jusqu'au niveau de la ceinture 30a. Cette seconde pièce 33 forme donc également la ceinture dans sa partie supérieure. Elle a par exemple une hauteur d'environ 8 cm sur les côtés et 10 cm en son centre.At the level of the area of the body corresponding to the belly, a second piece 33 covers the abdomen transversely and extends between the second parts 31 of the two legs which extend to the level of the belt 30a. This second piece 33 thus also forms the belt in its upper part. It has for example a height of about 8 cm on the sides and 10 cm in the center.

Dans la partie du corps correspondant au dos, une seconde pièce 34 recouvre transversalement le bas du dos au dessus des muscles grands fessiers (Gluteus maximus). Elle s'étend transversalement entre les deux secondes pièces 31 et forme la ceinture dans sa partie supérieure.In the part of the body corresponding to the back, a second piece 34 covers transversely the lower back above the gluteus maximus muscles (Gluteus maximus). It extends transversely between the two second pieces 31 and forms the belt in its upper part.

L'assemblage des différents panneaux du collant 30 pour la pratique du raid est réalisé selon une confection cintrée au niveau de l'articulation de chaque genou selon un angle de flexion dudit genou de l'ordre de 20°.The assembly of the various panels of the panty 30 for the practice of the raid is made according to a bent construction at the joint of each knee at a bending angle of the knee of the order of 20 °.

Dans le troisième exemple qui est illustré aux figures 6 à 8, le collant 40 est destiné aux cyclistes et comporte une partie supérieure avec bretelles. Comme pour le deuxième exemple, ne seront décrites de manière détaillée que les différences par rapport au collant 1 du premier exemple.In the third example which is illustrated in Figures 6 to 8 , the panty 40 is intended for cyclists and has an upper part with straps. As for the second example, only the differences with respect to the glue 1 of the first example will be described in detail.

Au niveau de la partie inférieure de la jambe, correspondant au mollet, une seconde pièce 41 présente les mêmes caractéristiques que la seconde pièce 2 du collant 1 du premier exemple.At the level of the lower part of the leg, corresponding to the calf, a second piece 41 has the same characteristics as the second piece 2 of the pantyhose 1 of the first example.

Au niveau de la partie du corps correspondant à l'extérieur des cuisses et des fesses, une seconde pièce 42 recouvre le bas du dos en descendant le long des jambes. Elle recouvre les muscles sacro-lombaires (Iliocostialis lumbrum), la face extérieure des muscles fessiers (Gluteus maximus), le grand trochanter (Trochanter major), la bandelette de Maissiat (Tractus iliotibialis) et la partie inférieure du vaste externe (Vastus lateralis). Cette seconde pièce 42 se prolonge vers le bas sur le ligament latéral externe (Lig. collaterale fubulare) et le ligament rotulien (Lig. patellae). Elle rejoint la seconde pièce 41 au niveau du ligament latéral externe (Lig. collatérale fibulare) et au niveau du ligament latéral interne (Lig. collaterale tibiale) et recouvre le ligament latéral interne (Lig. collaterale tibiale) pour rejoindre la seconde pièce 43, décrite ci-après, à la base du vaste interne (Vastus medialis). Cette seconde bande 42 remonte dans sa partie supérieure en un faisceau central dans le dos, le long de la colonne vertébrale et des muscles lombaires pour former la partie médiale 44 des bretelles.At the portion of the body corresponding to the outside of the thighs and buttocks, a second piece 42 covers the lower back down the legs. It covers the sacro-lumbar muscles (Iliocostialis lumbrum), the outer surface of the gluteal muscles (Gluteus maximus), the greater trochanter (Trochanter major), the iliotibialis band (Tractus iliotibialis) and the lower part of the outer vastus (Vastus lateralis). . This second piece 42 extends downwards on the lateral lateral ligament (Lig collaterale fubulare) and the patellar ligament (Lig patellae). It joins the second piece 41 at the level of the external lateral ligament (fibulare collateral ligament) and at the level of the internal lateral ligament (tibial collateral ligament) and covers the internal lateral ligament (tibial collateral ligament) to join the second piece 43, described below, at the base of the vastus internus (Vastus medialis). This second band 42 rises in its upper part in a central bundle in the back, along the spine and lumbar muscles to form the medial portion 44 of the straps.

Au niveau de la partie du corps allant de l'extérieur de l'abdomen à l'intérieur des cuisses, une seconde bande 43 compose, dans sa partie supérieure, la partie avant des bretelles 45, 45'. Elle descend en se prolongeant vers le bas en forme de parenthèse autour de l'abdomen, recouvrant les parties externes des muscles obliques de l'abdomen (Obliquus externus abdominis et Obliquus internus abdominis), l'épine iliaque antéro-supérieure (Spina iliaca anterior superior), le muscle long couturier et le muscle vaste interne (Vastus medialis). Cette seconde pièce 43 se termine entre la tubérosité fémorale interne (Epicondylus medialis) et la base du vaste interne (Vastus medialis) où elle rejoint la seconde pièce 42 décrite ci-dessus.At the part of the body from the outside of the abdomen to the inside of the thighs, a second band 43 composes, in its upper part, the front part of the straps 45, 45 '. It descends, extending in the form of a parenthesis around the abdomen, covering the external parts of the oblique muscles of the abdomen (Obliquus externus abdominis and Obliquus internus abdominis), the anterior superior iliac spine (Spina iliaca anterior superior), the long seamstress muscle and the extensive internal muscle (Vastus medialis). This second piece 43 ends between the internal femoral tuberosity (Epicondylus medialis) and the base of the vastus medialis (Vastus medialis) where it joins the second piece 42 described above.

De fausses coutures 46, 47 croisent la partie antérieure de la cuisse, entre les bords antérieurs des deux secondes pièces 42,43. La première fausse couture 46 part de la seconde pièce 43, une dizaine de centimètres sous la jonction supérieure 48 avec la seconde pièce 42 pour rejoindre cette dernière à mi-cuisse. La seconde fausse couture 47 part de la seconde pièce 43 à mi-cuisse, pour rejoindre la seconde pièce 42 quelques centimètres au dessus de la partie inférieure du muscle vaste interne (Vastus lateralis). Ces fausses coutures 46, 47 évitent l'écartement des deux bords communs desdites secondes pièces 42,43 lors de la flexion du genou.False seams 46, 47 intersect the anterior part of the thigh, between the anterior edges of the two second pieces 42,43. The first seam 46 starts from the second piece 43, about ten centimeters under the upper junction 48 with the second piece 42 to join the latter at mid-thigh. The second false seam 47 starts from the second piece 43 at mid-thigh, to join the second piece 42 a few centimeters above the lower part of the vastus medialis muscle (Vastus lateralis). These false seams 46, 47 avoid spacing the two common edges of said second pieces 42,43 during the flexion of the knee.

Au niveau de la partie du corps correspondant au ventre, une seconde pièce 49 recouvre transversalement le bas de l'abdomen entre les secondes pièces 43 des deux jambes. Cette seconde pièce 49 passe au niveau de l'ombilic dans sa partie supérieure une dizaine de centimètres au dessus de la symphyse pubienne (Symphysis pubica). Cette seconde pièce 49 a une hauteur d'environ 15 cm sur les côtés et 12 cm en son centre.At the level of the body portion corresponding to the belly, a second piece 49 covers the bottom of the abdomen transversely between the second pieces 43 of the two legs. This second piece 49 passes at the level of the umbilicus in its upper part about ten centimeters above the pubic symphysis (Symphysis pubica). This second piece 49 has a height of about 15 cm on the sides and 12 cm at its center.

Dans la partie du corps correspondant à la cage thoracique, une troisième pièce 50 recouvre les côtes, entre les secondes pièces 42 sur l'arrière et 43 sur l'avant. Cette troisième pièce 50 se termine sous les bras dans sa partie supérieure et rejoint la seconde pièce 42 dans sa partie inférieure, quelques centimètres au dessus de la crête iliaque (Crista iliaca).In the body part corresponding to the rib cage, a third piece 50 covers the ribs, between the second pieces 42 on the back and 43 on the front. This third piece 50 ends under the arms in its upper part and joins the second piece 42 in its lower part, a few centimeters above the iliac crest (Crista iliaca).

Comme cela ressort de la description ci-dessus, les bretelles, avec leur partie arrière 44 et leur partie avant 45, sont formées par la jonction des secondes pièces 42 et 43 dans la partie supérieure.As is apparent from the above description, the straps, with their rear portion 44 and their front portion 45, are formed by the junction of the second pieces 42 and 43 in the upper part.

De plus, dans le collant 40 pour cycliste l'assemblage des panneaux est réalisé selon une confection cintrée au niveau de l'articulation de chaque genou selon un angle de flexion du genou de l'ordre de 30°.In addition, in the tights 40 for cyclists the assembly of the panels is made according to a bent construction at the joint of each knee at a bending angle of the knee of the order of 30 °.

La zone d'entrejambe ne comporte pas de troisième pièce à élasticité supérieure, mais comme tout cuissard pour cycliste un matelassage intérieur, par exemple en peau de chamois.The crotch area has no third piece with superior elasticity, but like all cycling shorts an inner padding, for example chamois.
