The band connects ends of the support to form a closed ring around the thigh.

Description

La présente invention concerne un harnais de sécurité utilisé par les alpinistes, grimpeurs où tout autre personne effectuant des activités en tension ou en suspension sur une corde et pouvant s'adapter rapidement sur des utilisateurs de taille différente qui comprend essentiellement des pièces de portance du corps en cas de chute, constituées d'une ceinture, de deux sangles de cuisses fermées ou tour de cuisses reliées à la ceinture sur la face centrale de l'utilisateur par des sangles. On définit le diamètre ou le périmètre de la cuisse de l'utilisateur par le diamètre ou périmètre extérieur de la cuisse qui peut varier selon la présence ou non de vêtement et selon leur épaisseur.The present invention relates to a safety harness used by mountaineers, climbers where any other person performing activities in tension or suspension on a rope and can adapt quickly to users of different size that includes essentially body lift parts in the event of a fall, consisting of a belt, two thigh straps closed or thighs connected to the belt on the center face of the user by straps. We define the diameter or the perimeter of the thigh of the user by the diameter or outer perimeter of the thigh which may vary depending on the presence or absence of clothing and according to their thickness.

Pour être efficace, le harnais doit être en permanence en bonne place sur le corps de l'utilisateur, c'est-à-dire très près du corps pour éviter tout déplacement non souhaité des sangles par rapport au corps en cas de chute.To be effective, the harness must be permanently on the body of the user, that is to say very close to the body to avoid any unwanted movement of straps in relation to the body in case of fall.

La plupart des harnais sont réglables pour des tailles et des morphologies d'utilisateurs différentes, dans les écoles d'escalade par exemple, et mais aussi pour un même utilisateur selon l'épaisseur des vêtements portés, d'où le grand intérêt d'adapter rapidement, facilement et de façon continuelle le harnais, surtout le tour de cuisse du harnais au diamètre de la cuisse en raison du rôle essentiel de portance de cet élément en cas de chute où l'utilisateur est pendu par l'intermédiaire du harnais.Most harnesses are adjustable for sizes and shapes of different users, in climbing schools for example, but also for the same user according to the thickness of the clothes worn, hence the great interest to adapt quickly, easily and continuously the harness, especially the thigh of the harness diameter of the thigh because of the essential role of lift of this element in case of fall where the user is hanged through the harness.

Il est connu du brevet DE2933771 un harnais de sécurité constitué d'une ceinture, d'un tour de cuisse de dimension fixe pour chaque jambe et fixé à la ceinture par des sangles.Patent DE2933771 discloses a safety harness consisting of a belt, a leg circumference of fixed size for each leg and attached to the belt by straps.

Dans le brevet EP819018, les deux extrémités de chaque tour de cuisse comportent une boucle dans laquelle coulisse une sangle de soutien reliée à la ceinture. Ainsi chaque tour de cuisse reste ouvert et se resserre pour s'adapter à la taille de la cuisse du porteur quand la sangle de portance est tirée. Mais pour donner en permanence une position correcte du tour de cuisse par rapport à la cuisse, la sangle doit être ajustée précisément en longueur par des moyens de réglage fixé sur les moyens de portance du harnais. Ces moyens de réglage ne peuvent être satisfaisants puisque l'état de serrage autour de la cuisse dépend de la distance de la ceinture à la cuisse et que cette distance varie lorsque la jambe est pliée par rapport au corps.In patent EP819018, the two ends of each leg turn comprise a loop in which slides a support strap connected to the belt. So every turn thigh stays open and tightens to fit the size of the wearer's thigh when the lift strap is pulled. But to permanently give a correct position of the turn of thigh in relation to the thigh, the strap must be precisely adjusting means fixed on the lift means of the harness. These adjustment means may be satisfactory since the tightening condition around the thigh depends on the distance of thigh belt and that distance varies when the leg is bent in relation to the body.

De façon connue également, le réglage du tour de cuisse se fait grâce à une boucle métallique de réglage qui coulisse sur des sangles entourant la cuisse et en resserre ou en agrandit la longueur de portance pour l'adapter au diamètre de la cuisse du porteur. Comme les éléments de réglage sont des éléments de portance qui doivent pouvoir supporter plus de 1500 kilos, la boucle doit être très résistante et de sécurité contre tout relâchement en cas de chute. Une telle boucle est en métal, donc lourde et nuit à la légèreté de l'ensemble de l'équipement, elle est onéreuse, et exige un raccordement compliqué du bout de sangle apportant des étapes supplémentaires de couture au cours de la fabrication du harnais.In a known manner also, the adjustment of the leg circumference is done through a loop adjustment device that slides on straps around the thigh and tightens or enlarges the length of lift to adapt to the diameter of the thigh of the wearer. As the adjustment elements are lift elements that must be able to support more than 1500 kilos, the buckle must be very resistant and safety against any looseness in case of fall. Such a loop is metal, so heavy and harms the lightness of the whole the equipment, it is expensive, and requires a complicated connection of the end of the strap providing additional sewing steps during the manufacturing of the harness.

En cours d'utilisation, le réglage est peu aisé et peu rapide, puisque les deux mains sont nécessaires pour régler des sangles de portance résistantes qui ont tendance à durcir avec le temps. De plus, la force à exercer sur la boucle pour faire coulisser la sangle doit être importante.In use, the setting is not easy and not fast, since both hands are needed to adjust heavy duty lift straps that tend to harden with the weather. In addition, the force to be exerted on the buckle to slide the strap must be important.

L'invention vise à résoudre ces inconvénients en proposant de nouveaux moyens d'ajustage et de maintien qui d'une façon surprenante n'ont pas à assurer la portance du corps de l'utilisateur en cas de chute et qui permettent de maintenir le support de cuisse en bonne position sans pratiquer, comme dans l'art antérieur, le serrage d'une boucle faisant partie des éléments de portance. De plus, le dispositif selon l'invention permet de couvrir plusieurs tailles. Ainsi, avec seulement deux types de harnais, couvrant chacun les trois tailles des harnais traditionnels, on peut équiper l'ensemble des morphologies des personnes, de l'enfant à l'adulte, aptes à faire de l'escalade. Par exemple le premier type convient pour des périmètres de cuisse allant de 40 à 60 cm et le second type de 50 à 70 cm.The invention aims to solve these disadvantages by proposing new means of adjustment and maintenance which in a surprising way do not have to ensure the lift of the body of the user in case of a fall and which make it possible to maintain the thigh support in good position without practicing, as in the prior art, the tightening of a loop forming part of lift elements. In addition, the device according to the invention makes it possible to cover several sizes. Thus, with only two types of harness, each covering the three sizes of traditional harnesses, we can equip all the morphologies of people, the child to adults, suitable for climbing. For example, the first type is suitable for thigh perimeters ranging from 40 to 60 cm and the second type from 50 to 70 cm.

Le tour de cuisse selon l'invention comporte un dispositif permettant de l'adapter et de le maintenir rapidement à la cuisse de l'utilisateur sans modifier la longueur de l'élément de portance en charge en cas de chute, soit en plaçant, sur le devant de la cuisse, des moyens de maintien formant un anneau avec le support de cuisse, pour maintenir celui-ci autour de la cuisse de façon optimale, soit par des épaisseurs s'intercalant entre le tour de cuisse et la cuisse de l'utilisateur, soit en modifiant temporairement la longueur du tour de cuisse en contact serrée avec la cuisse de l'utilisateur et en lui permettant de revenir à sa longueur de portance en cas de chute.The thigh circumference according to the invention comprises a device enabling it to be adapted and quickly hold it to the thigh of the user without changing the length of the element of load in the event of a fall, or by placing on the front of the thigh maintaining a ring with the thigh support, to maintain it around the thigh in an optimal way, either by thicknesses between the thigh circumference and the the thigh of the user, either temporarily changing the length of the leg circumference tight contact with the user's thigh and allowing him to return to his length of lift in case of fall.

Chaque tour de cuisse est donc équipé de son moyen de maintien autonome qui n'interagit avec aucun autre élément du harnais.Each leg circumference is therefore equipped with its independent means of support which does not interact with any other element of the harness.

Comme ces moyens n'interviennent pas directement sur la portance du tour de cuisse, ils n'ont pas besoin d'assurer la sécurité de portance et d'être aussi conséquents, rigides et solides. En cas de chute, ces moyens de maintien selon l'invention se distendent ou se compriment et la cuisse repose sur le support de cuisse en toute sécurité comme de façon connue. En effet le fait que la totalité de la longueur de portance du tour de cuisse ne soit pas en permanence en contact avec la cuisse principalement sur sa partie avant n'empêche pas une bonne rétention du corps sur le support de cuisse en cas de chute et apporte même un certain confort en position suspendue de l'utilisateur. As these means do not intervene directly on the lift of the thigh circumference, they do not need to provide lift safety and be as consistent, rigid and solid. In the event of a fall, these holding means according to the invention are distended or compress and the thigh rests on the thigh support safely as well as known. Indeed, the fact that the entire lift length of the thigh circumference is not permanently in contact with the thigh mainly on its front part does not prevent a good retention of the body on the thigh support in case of fall and even brings some comfort in the suspended position of the user.

L'invention concerne donc un harnais de sécurité comportant des pièces de portance du corps de l'utilisateur en cas de chute constituées d'une ceinture, de deux tours de cuisse fermés reliés à la ceinture par des sangles de portance, caractérisé en ce qu'il comprend des moyens de maintien ajustant et maintenant chaque tour de cuisse contre la cuisse de l'utilisateur mais n'assurant pas la portance en cas de chute.The invention therefore relates to a safety harness comprising lift pieces of the body of the user in case of fall consisting of a belt, two thighs closed connected to the belt by lift straps, characterized in that it comprises means keeping fit and keeping each leg loop against the user's thigh but not providing lift in the event of a fall.

Selon un premier mode de réalisation, les moyens de maintien comportent un bandeau d'ajustage et de maintien qui est fixé à un support de cuisse constitué par la partie du tour de cuisse destinée à venir en contact avec la partie arrière et les parties latérales de la cuisse, et qui rapproche les extrémités du support de cuisse pour le faire coller cuisse au moins contre la partie arrière et les parties latérales de la cuisse et former tout autour de la cuisse un anneau fermé constitué par le support de cuisse sur la partie arrière et les parties latérales de la cuisse et par le bandeau de maintien sur la partie avant de la cuisse, sans modifier la longueur de portance du tour de cuisse en cas de chute. Le bandeau de maintien est fixé coulissant dans le support de cuisse en l'un au moins de deux points limites situés là où le support de cuisse quitte le contact avec la cuisse. Les moyens de maintien comportent aussi un moyen pour faire varier la longueur utile au-dessus de la partie avant de la cuisse du bandeau de maintien, ledit moyen étant constitué d'un bloqueur automatique du bandeau de maintien au voisinage d'au moins l'un desdits points limites. En variante, le bandeau de maintien est formé de deux demi-bandes dont une extrémité est fixée au support de cuisse et dont l'autre extrémité est libre, l'extrémité libre d'une demi-bande coopérant avec l'extrémité libre de l'autre demi-bande pour faire varier la longueur du bandeau de maintien.According to a first embodiment, the holding means comprise a headband adjusting and holding which is attached to a thigh support constituted by the part of the turn of thigh intended to come into contact with the rear part and the lateral parts of the thigh, and which brings the ends of the thigh support together to make it stick to the thigh at least against the back and the sides of the thigh and form around the thigh a ring closed constituted by the support of thigh on the back part and the lateral parts of the thigh and by the headband on the front part of the thigh, without changing the length of lift of the thigh in the event of a fall. The headband is slidably attached in the thigh support in at least one of two endpoints located where the thigh support leaves the contact with the thigh. The holding means also comprise means for vary the useful length above the front part of the thigh of the support band, said means being constituted by an automatic blocking of the holding strip in the vicinity at least one of said limit points. Alternatively, the retaining strip is formed of two half strips, one end of which is attached to the thigh support and the other end of which is free, the free end of a half-band cooperating with the free end of the other half-band to vary the length of the holding strip.

Selon une autre variante, le bandeau de maintien est constitué d'au moins une bande élastique de maintien suffisamment longue pour fonctionner dans son domaine d'élasticité avec les différents périmètres de cuisses.According to another variant, the holding strip consists of at least one strip holding elastic long enough to operate in its elastic range with the different perimeters of thighs.

Le bandeau de maintien est un anneau fermé qui fait tout le tour de la cuisse et qui peut librement coulisser dans un fourreau du support de cuisse ou est un anneau ouvert qui est logé dans un fourreau du support de cuisse, qui entoure partiellement la cuisse et dont les deux extrémités sont fixées sur le support de cuisse.The headband is a closed ring around the thigh and can slide freely in a sheath of the thigh support or is an open ring that is housed in a sheath of the thigh support, which partially surrounds the thigh and whose two ends are attached to the thigh support.

Le fourreau est continu ou discontinu formé des passants.The sheath is continuous or discontinuous formed passers.

D'une autre façon, les passants sont montés fixes sur une extrémité et montés démontables sur l'autre extrémité afin de pouvoir s'ouvrir pour changer le bandeau de maintien, avantageusement surtout quand le bandeau se présente sous forme d'eanneau déjà fermé. In another way, bystanders are mounted fixed on one end and mounted removable on the other end so you can open to change the banner of maintenance, advantageously especially when the headband is in the form of an eanneau already closed.

Le support de cuisse est constitué d'une bande de contact faite d'un complexe matelassé venant en contact avec la cuisse d'une part et d'une bande de finition vers l'extérieur d'autre part, les deux bandes étant réunies en bordure sur chacune de leurs deux tranches par une demi-sangle de portance et formant entre elles un fourreau destiné à recevoir le bandeau de maintien.The thigh support consists of a contact strip made of a complex quilted material coming into contact with the thigh on the one hand and a finishing band towards the outside on the other hand, the two bands being joined at the edge on each of their two sliced by a half-strap of lift and forming between them a sleeve intended to receive the headband.

D'une autre façon, le support de cuisse est constitué d'une bande de contact faite d'un complexe matelassé venant en contact avec la cuisse, d'une bande de séparation et d'une bande de finition, les bords de chaque constituant du support de cuisse étant solidarisés par un biais de finition, l'espace compris entre la bande de contact et la bande de séparation formant un premier fourreau destiné à recevoir le bandeau de maintien, et l'espace compris entre la bande de séparation et la bande de finition formant un second fourreau destiné à recevoir la sangle de liaisonIn another way, the thigh support consists of a contact strip made of a quilted complex coming into contact with the thigh, a separation band and a finishing strip, the edges of each component of the thigh support being secured by a finishing angle, the space between the contact strip and the separation strip forming a first sheath for receiving the holding strip, and the space between the separation strip and the finishing strip forming a second sleeve intended to receive the binding strap

Selon un deuxième mode de réalisation, les moyens de maintien sont constitués d'un corps faisant épaisseur et intercalé entre le support de cuisse et la cuisse de l'utilisateur, sans modifier la longueur de l'élément de portance en charge en cas de chute.According to a second embodiment, the holding means consist of a body being thick and interposed between the thigh support and the thigh of the user, without change the length of the load bearing element in the event of a fall.

Selon un troisième mode de réalisation, les moyens de maintien sont constitués d'une partie d'une sangle de liaison reliant le support de cuisse à la sangle de portance du support de cuisse comportant une partie de longueur variable se repliant en accordéon grâce à une partie élastique de tension accrochée en parallèle avec ladite partie de longueur variable sans que soit modifiée la longueur de l'élément de portance en charge en cas de chute.According to a third embodiment, the holding means consist of a part of a connecting strap connecting the thigh support to the lift strap of the support of leg having a portion of variable length folding accordion with a part voltage elastic hooked in parallel with said variable length portion without the length of the load bearing element in the event of a fall is changed.

    • Un harnais de sécurité (fig 1) comprend essentiellement des pièces de portance du corps en cas de chute constituées d'une ceinture (1), de deux tours de cuisse (2) reliés à la ceinture (1) par des sangles de portance (6). Ces pièces de portance sont de sécurité et doivent être très solides et capables de supporter une charge de plus de 1500 kilos.A safety harness (FIG. 1) essentially comprises lift pieces of the body in the event of a fall consisting of a belt (1), two leg loops (2) connected to the belt (1) by lifting straps (6). These lift pieces are safety and must be very strong and able to support a load of over 1500 kilos.

    Les tours de cuisse de l'art antérieur entourent, en cours d'utilisation, totalement la cuisse en contact serré et correctement maintenu en place sur celle-ci par les pièces de portance elles-même, soit que le tour de cuisse corresponde exactement au périmètre de la cuisse, soit qu'il comporte un moyen de réglage de la longueur pour l'adapter exactement au périmètre de la cuisse. Ce moyen de réglage doit être très solide, car il assure aussi la portance.The leg loops of the prior art surround, in use, totally the thigh in close contact and properly held in place on it by the pieces of lift itself, ie that the thigh circumference corresponds exactly to the perimeter of the thigh, or that it comprises a means of adjusting the length to adapt it exactly to the perimeter of the thigh. This means of adjustment must be very solid, because it also ensures the lift.

    Chaque tour de cuisse (2) selon l'invention (fig. 1b) comporte un périmètre interne beaucoup plus grand que celui de la cuisse (5) et est constitué d'une partie large ou support de cuisse (3), de deux sangles de liaison (4) prolongeant le support de cuisse (3) et se réunissant pour former en remontant vers la ceinture (1), la sangle de portance (6) fixée à la ceinture (1). Ces pièces assurent la portance et sont très solides. Aussi simplement constitué, le tour de cuisse (2) pourrait se déplacer sur la cuisse (5) car il ne la serre pas. En particulier, en cas de chute, le tour de cuisse (2) pourrait descendre le long de la cuisse (5) et se trouver en mauvaise position pour supporter le corps du porteur en cas de chute.Each thigh loop (2) according to the invention (FIG 1b) has an internal perimeter much larger than that of the thigh (5) and consists of a wide part or support of thigh (3), two connecting straps (4) extending the thigh support (3) and meeting to form upwardly to the belt (1), the lift strap (6) attached to the belt (1). These parts provide lift and are very strong. Also simply constituted, the turn of leg (2) could move on the thigh (5) because it does not tighten. In particular, in case of fall, the thigh loop (2) could descend along the thigh (5) and be in poor position to support the wearer's body in case of a fall.

    Pour résoudre ce problème, le tour de cuisse (2) selon l'invention comporte en plus, des moyens d'ajustage et de maintien du support de cuisse (3) en position sur la cuisse (5) en permanence au cours de son utilisation. Ainsi, le tour de cuisse (2) peut s'adapter rapidement à des périmètres de cuisses différents sans modifier la longueur du tour de cuisse de portance (2) en charge en cas de chute.To solve this problem, the thigh loop (2) according to the invention also comprises means for adjusting and maintaining the thigh support (3) in position on the thigh (5) in permanence during its use. Thus, the thigh loop (2) can adapt quickly to different thigh perimeters without changing the length of the thigh lift (2) load in case of fall.

    Selon un premier mode de réalisation de l'invention (figures 1 à 14), le support de cuisse (3) est maintenu en permanence au cours de son utilisation, en contact étroit avec la partie arrière (8) et les deux parties latérales (9) de la cuisse (5).According to a first embodiment of the invention (FIGS. 1 to 14), the support of thigh (3) is permanently maintained during its use, in close contact with the rear part (8) and the two lateral parts (9) of the thigh (5).

    Les moyens d'ajustage et de maintien du tour de cuisse (2) en position sur la cuisse (5) en permanence au cours de son utilisation se compose d'un bandeau de maintien (7) allongé qui relie le support de cuisse (3) en deux points limites de contact (11, 12) du support de cuisse (3) avec la cuisse (5). Ces points limites de contact (11, 12) sont situés à proximité des extrémités du support de cuisse (3), là où le support de cuisse (3) se sépare de la cuisse (5).Means for adjusting and maintaining the thigh circumference (2) in position on the thigh (5) permanently during its use consists of an elongated holding strip (7) which connects the thigh support (3) to two contact points (11, 12) of the support of thigh (3) with the thigh (5). These contact endpoints (11, 12) are located near the ends of the thigh support (3), where the thigh support (3) separates from the thigh (5).

    Le bandeau de maintien (7) s'appuie sur la partie supérieure avant (10) de la cuisse et maintient plaqué contre la partie arrière (8) et les parties latérales (9) de la cuisse, le support de cuisse (3) jusqu'au niveau des deux points limites (11,12). Puisqu'il n'a pas de rôle de portance, le bandeau de maintien (7) est beaucoup plus petit que les éléments assurant la portance et est constitué d'une bande ou cordon, de préférence en tissé élastique sur toute sa longueur ou faite de partie tissée élastique et de partie non élastique. Sa résistance limite à la traction de l'ordre de la dizaine de kilos est bien suffisant. La cuisse (5) se trouve alors totalement entourée de façon serrée par le support de cuisse (3) sur ses parties arrière (8) et latérales (9) et par le bandeau de maintien (7) au moins sur sa partie supérieure avant (10) restante.The holding strip (7) bears on the upper front part (10) of the thigh and keeps pressed against the rear part (8) and the lateral parts (9) of the thigh, the support thigh (3) to the level of the two endpoints (11,12). Since he does not have a role of the support strip (7) is much smaller than the elements providing the lift and is made of a band or cord, preferably elastic woven all over its length or made of elastic woven part and non-elastic part. Its resistance limits to traction of the order of ten kilos is good enough. The thigh (5) is then totally enclosed by the thigh support (3) on its rear parts (8) and (9) and by the holding strip (7) at least on its upper front part (10) remaining.

    Selon une première variante(figures 2a, 2b, 2c et 3), le bandeau de maintien (7) en forme d'un cordon relie les deux points limites (11, 12) du support de cuisse (3). L'une des extrémités du cordon est fixée à l'intérieur d'un côté du support de cuisse (3) en un premier point d'ancrage (16), par couture par exemple, tandis que l'autre extrémité traverse de l'intérieur vers l'extérieur l'autre côté du support de cuisse (3) à travers un passage (18) en un second point d'ancrage (17) suivi d'un serre-cordon du type de ceux commercialisés sous la marque déposée « TANKA » ®.According to a first variant (FIGS. 2a, 2b, 2c and 3), the holding strip (7) in form of a cord connects the two end points (11, 12) of the thigh support (3). One of ends of the cord is fixed inside one side of the thigh support (3) in a first anchoring point (16), for example by sewing, while the other end passes through inside out the other side of the thigh support (3) through a passage (18) in one second anchor point (17) followed by a cord clamp of the type of those marketed under the registered trademark "TANKA" ®.

    Avantageusement, (figures 2a, 2b, 2c), le serre cordon est enfermé dans une capsule semi-rigide (19), elle-même solidaire sur le tour de cuisse. Ainsi pour positionner le support de cuisse (3), on tire sur le cordon ; le serre-cordon vient se bloquer contre un bord de la capsule (19) et libère suffisamment le passage dans le serre-cordon pour que le cordon glisse. Quand on arrête de tirer, le serre-cordon revient à sa position initiale et bloque le cordon à la dimension voulue. Pour ajuster le tour de cuisse (2) à une taille de cuisse (5) plus grande, une simple pression sur la capsule (19) appuie sur le support du serre-cordon qui ainsi libère l'extrémité libre du cordon et agrandit ainsi l'anneau formé autour de la cuisse (5) par le support de cuisse (3) et le bandeau de maintien (7) jusqu'à la dimension requise. Ce serre-cordon a de préférences la forme d'un bouton poussoir (20) accessible par le dessus.Advantageously, (FIGS. 2a, 2b, 2c), the cord greenhouse is enclosed in a capsule semi-rigid (19), itself secured to the thigh. So to position the support thigh (3), pull on the cord; the cord clamp comes to hang against an edge of the capsule (19) and sufficiently releases the passage in the cord holder for the cord to slide. When you stop pulling, the cord clamp returns to its original position and locks the cord to the desired dimension. To adjust the thigh circumference (2) to a larger thigh size (5), a a simple pressure on the capsule (19) presses on the support of the cord-holder which thus releases the free end of the cord and thus enlarges the ring formed around the thigh (5) by the thigh support (3) and the retaining band (7) to the required size. This cord clamp preferably has the form of a push button (20) accessible from above.

    D'une autre façon, (fig 3), un moyen de blocage (21), par pincement et frottement par exemple, de l'extrémité libre du cordon permet de reprendre ou de libérer une longueur de cordon et ainsi d'éloigner ou de rapprocher l'un de l'autre les deux points limites (11, 12) selon que l'on veut ajuster ou libérer le tour de cuisse (2). Avantageusement, le serre-cordon se serre et se desserre par une manipulation d'une seule main.In another way, (FIG. 3), a locking means (21), by pinching and rubbing by example, the free end of the cord allows to resume or release a length of cord and thus to move the two limit points away from or towards each other (11, 12) depending on whether you want to adjust or release the leg circumference (2). Advantageously, the cord clamp squeezes and loosens by one-handed manipulation.

    Selon une deuxième variante (fig 4a, 4b), le bandeau de maintien (7) est constitué de deux demi-bandes (22, 23) qui chacune est fixée à l'une de leurs deux extrémités en l'un (16) des points d'ancrage sur le support de cuisse (3) et dont les deux autres extrémités comportent un moyen de réglage et de blocage de la longueur du bandeau de maintien (7), tel qu'un système à boucle (25) coopérant avec une demi-bande à trous ou à pincement ou une bande auto-agrippante (26) à crochets et boucles du même type que celle commercialisée sous la marque déposée « VELCRO »® (fig. 5)According to a second variant (FIG. 4a, 4b), the holding strip (7) consists of two half-strips (22, 23) each of which is fixed at one of their two ends in one (16) anchoring points on the thigh support (3) and whose other two ends comprise means for adjusting and blocking the length of the holding strip (7), such as that a loop system (25) cooperating with a half-band with holes or pinching or a Velcro strap (26) with hooks and loops of the same type as that marketed under the trademark "VELCRO" ® (Fig. 5)

    Selon une première façon (figure 4 a), les points d'ancrage (16, 17) des extrémités des demi-bandes (22, 23) sont positionnés tous les deux à l'intérieur du support de cuisse (3) ; les points d'ancrage (16, 17) sont alors voisins des points limites (11, 12). Le moyen de réglage et de blocage de la longueur du bandeau de maintien (7) est alors en dessous d'une sangle de liaison (4).In a first way (FIG. 4 a), the anchoring points (16, 17) of the ends of the half strips (22, 23) are positioned both inside the thigh support (3); the anchoring points (16, 17) are then close to the end points (11, 12). The adjustment means and locking the length of the holding strip (7) is then below a strap of link (4).

    Selon une deuxième façon (figure 4 b, 5), un point d'ancrage (16) de l'extrémité d'une demi-bande (22) est au voisinage d'un point limite (11) et est fixé à l'intérieur du support de cuisse (3), et son autre extrémité traverse l'autre côté du support de cuisse (3) de l'intérieur vers l'extérieur au deuxième point limite (12) et son extrémité coopère avec le moyen de réglage de l'autre demi bande. (fig 4b, 5). Le moyen de réglage et de blocage de la longueur du bandeau de maintien (7) est alors à l'extérieur du support de cuisse (3).In a second way (FIG. 4b, 5), an anchor point (16) of the end of a half-band (22) is in the vicinity of a limit point (11) and is fixed inside the support of thigh (3), and its other end passes through the other side of the thigh support (3) from the inside outward to the second limit point (12) and its end cooperates with the means of adjusting the other half band. (Fig 4b, 5). The means for adjusting and locking the length the holding strip (7) is then outside the thigh support (3).

    Selon une troisième variante non évidente et fonctionnant en donnant de bons résultats de façon tout à fait surprenante pour un dispositif aussi simple et aussi efficace, (fig 6, 7, 8, 9, 10, 11, 12, 13 et 14), le bandeau de maintien (7) est simplifié à l'extrême, sans ajout de moyen de réglage supplémentaire qui compliquent toujours la fabrication, augmentent leurs coûts, alourdissent le harnais et rendent son usage moins aisé. Ledit bandeau de maintien (7) est constitué une bande élastique dont les propriétés physiques sont telles qu'elle est capable à la fois de serrer et positionner le tour de cuisse (2) sur des cuisses de petite taille et se distendre suffisamment pour être encore confortable pour les cuisses de grande taille. Il est dit automatique puisqu'il n'utilise comme moyen d'ajustage que la capacité d'extension élastique de la bande.According to a third variant that is not obvious and works with good results quite surprisingly for such a simple and efficient device (fig 6, 7, 8, 9, 10, 11, 12, 13 and 14), the holding strip (7) is simplified to the extreme, without adding means of additional adjustment which always complicate the manufacture, increase their costs, weigh down the harness and make it less easy to use. Said holding strip (7) consists of an elastic band whose physical properties are such that it is capable of both to tighten and position the thigh (2) on thighs of small size and distend sufficiently to be comfortable for large thighs. It is said automatic since it only uses as a means of adjustment the elastic extension capacity Of the band.

    On parvient à y remédier en proposant une bande élastique qui fonctionne dans son domaine d'élasticité pour toutes les tailles de cuisse (5), grâce à des paramètres physiques choisis tels que sa longueur et son élasticité linéaire.We manage to remedy this by proposing an elastic band that works in its elasticity range for all thigh sizes (5), thanks to physical parameters chosen such as its length and its linear elasticity.

    La fonction du bandeau de maintien (7) élastique est de rapprocher le support de cuisse (3) contre la cuisse (5) au plus près, sans faire de plis sur le support de cuisse (3) de façon que le support de cuisse (3) soit au contact au plus serrée sur les parties arrière (8) et latérales de la cuisse (9). Ainsi, en cas de chute, la sangle est immédiatement en contact avec la cuisse (5) en bonne position de soutien, sans flottement.The function of the elastic holding strip (7) is to bring the support of thigh (3) against the thigh (5) as close as possible, without making any creases on the thigh support (3) of the thigh support (3) is in close contact with the rear parts (8) and lateral of the thigh (9). Thus, in the event of a fall, the strap is immediately in contact with the thigh (5) in a good supporting position, without fluttering.

    La table suivante donne les élongations du bandeau de maintien (7) lorsqu'une extrémité de celui-ci est attachée en un point fixe et que différents poids sont suspendus à son autre extrémité. Harnais 1 pour les périmètres de cuisse de 40 à 60 cm: longueur du bandeau de maintien au repos, sans tension 38 cm longueur du bandeau de maintien chargé de 50 g 40 cm longueur du bandeau de maintien chargé de 600 g 50 cm longueur du bandeau de maintien chargé de 1300 g 60 cm Harnais 2 pour les périmètres de cuisse de 50 à 70 cm: longueur du bandeau de maintien au repos, sans tension 46 cm Longueur du bandeau de maintien chargé de 50 g 50 cm longueur du bandeau de maintien chargé de 1350 g 60 cm longueur du bandeau de maintien chargé de 1550 g 70 cm The following table gives the elongations of the holding strip (7) when one end thereof is attached at a fixed point and different weights are suspended at its other end. Harness 1 for thigh perimeters of 40 to 60 cm: length of the support strip at rest, without tension 38 cm length of the holding strip loaded with 50 g 40 cm length of the holding strip loaded with 600 g 50 cm length of the holding strip loaded with 1300 g 60 cm Harness 2 for thigh perimeters of 50 to 70 cm: length of the support strip at rest, without tension 46 cm Length of the 50 g 50 cm length of the holding strip loaded with 1350 g 60 cm length of the holding strip loaded with 1550 g 70 cm

    Selon une première façon, le bandeau de maintien (7) élastique forme un anneau fermé qui coulisse librement dans le support de cuisse (3), soit en étant totalement enfermé dans un fourreau (30, 35) du support de cuisse (3) (fig 6, 7), soit en y étant maintenu grâce à des passants (32), comme une ceinture autour de la taille d'un pantalon (fig 8, 9, 10, 11, 12). In a first way, the elastic holding strip (7) forms a closed ring which slides freely in the thigh support (3), either while being totally enclosed in a sleeve (30, 35) of the thigh support (3) (FIG. 6, 7), or by being held there by means of passers (32), such as a belt around the waist of a pair of trousers (Figs. 8, 9, 10, 11, 12).

    Le support de cuisse (3) est constitué d'une bande de contact (27) faite d'un complexe matelassé composé de couches de mousse et de tissu venant en contact avec la cuisse (5) d'une part et d'une bande de finition (28) vers l'extérieur d'autre part. La bande de contact (27) et la bande de finition (28) sont réunis en bordure, par couture par exemple, sur chacune de leurs deux tranches par une demi-sangle de portance (29) qui ont chacune une résistance à la traction supérieure à 900 kilos. L'espace vide, constitué entre la bande de contact (27) et la bande de finition (28) constitue un fourreau (30) ouvert aux extrémités du support de cuisse (3) à proximité des points limites (11, 12).The thigh support (3) consists of a contact strip (27) made of a complex quilted consisting of layers of foam and fabric coming into contact with the thigh (5) on the one hand and a finishing band (28) on the other hand. The contact band (27) and the finishing band (28) are joined at the edge, by sewing, for example, on each of their two slices by a half-lift strap (29) which each have a resistance to the traction superior to 900 kilos. The empty space formed between the contact strip (27) and the finishing strip (28) constitutes a sheath (30) open at the ends of the thigh support (3) near the endpoints (11, 12).

    Selon les figures 8 et 9, la bande de finition (28) est discontinue et forme ainsi des espaces libres laissant entrevoir le bandeau de maintien (7) et des morceaux de bande de finition (28) constituant des passants (32) maintenant le bandeau de maintien (7). Si le bandeau de maintien (7) est usé ou détérioré, il est possible de le changer. Il suffit de le glisser ouvert dans le fourreau (30) puis de raccorder les deux extrémités pour former un anneau fermé par aboutement des extrémités. En variante, pour changer facilement le bandeau de maintien (7) qui se présente sous la forme d'un anneau déjà fermé, les passants (32) sont montés fixes d'un côté et s'ouvrent de l'autre côté soit qu'ils soient montés détachables par bouton pression, liaison boucle et crochets « VELCRO »®, ou analogue, soit qu'ils soient constitués d'un crochet fermé en matière rigide pouvant s'ouvrir par déformation élastique.According to FIGS. 8 and 9, the finishing strip (28) is discontinuous and thus forms free spaces showing the holding strip (7) and pieces of tape finish (28) constituting loops (32) holding the holding strip (7). If the holding strip (7) is worn or deteriorated, it is possible to change it. Just drag it open in the sleeve (30) and then connect the two ends to form a ring closed by butting ends. Alternatively, to easily change the banner of holding (7) which is in the form of an already closed ring, the loops (32) are fixed on one side and open on the other side, whether they are detachably mounted "VELCRO" ® hook-and-loop, hook and loop fasteners, or the like, whether consisting of a closed hook made of rigid material that can be opened by elastic deformation.

    En variante des modèles de tours de cuisse (2) des figures 6, 7, 8 et 9, le support de cuisse (3) est constitué de la bande de contact (27) faite du complexe matelassé destiné à entrer en contact avec la cuisse (5), d'une bande de séparation (33) et d'une bande de finition (28) continue ou discontinue formant des passants (32) comme décrits ci dessus. Les deux bords de chaque constituants du support de cuisse (3) sont solidarisés par un biais de finition (34). L'espace libre entre le complexe matelassé et la bande de séparation (33) forme un premier fourreau (35) destiné à recevoir le bandeau de maintien (7), et l'espace libre entre la bande de séparation (33) et la bande de finition (28) forme un second fourreau (36) destiné à recevoir la sangle de liaison (4).As a variant of the thigh turn models (2) of FIGS. 6, 7, 8 and 9, the support of thigh (3) consists of the contact strip (27) made of the quilted complex for contact the thigh (5), a separating band (33) and a finishing band (28) continuous or discontinuous forming passers (32) as described above. Both edges of each component of the thigh support (3) are secured by a finishing bias (34). The free space between the quilted complex and the separation strip (33) forms a first sleeve (35) for receiving the holding strip (7), and the free space between the strip (33) and the finishing strip (28) forms a second sleeve (36) for receive the connecting strap (4).

    Selon une seconde façon (schéma fig 14), le bandeau de maintien (7) élastique ne forme pas un anneau fermé mais constitue une partie d'anneau dont les deux extrémités sont maintenues fixes, en des points d'ancrage (16, 17) positionnés sur le support de cuisse (3) au-delà des points limites (11, 12). La longueur du bandeau de maintien (7) doit être suffisante pour s'adapter à tous les périmètres de cuisse dans le domaine d'extension élastique du matériau du bandeau de maintien (7). Par exemple, le harnais 1 adaptable aux périmètres de cuisse allant de 40 à 60 cm ,possède un tour de cuisse d'environ 38 cm, un support de cuisse de 36 cm de longueur pour une largeur de 6 cm. Le bandeau a une longueur de 34 cm. Le harnais 2 adaptable aux périmètres de cuisse allant de 50 à 70 cm, possède un tour de cuisse d'environ 46 cm, un support de cuisse de 42 cm de longueur pour une largeur de 6 cm. Le bandeau a une longueur de 38 cmIn a second way (FIG. 14), the elastic holding strip (7) shape not a closed ring but constitutes a ring part whose two ends are held fixed at anchor points (16, 17) positioned on the thigh support (3) beyond limit points (11, 12). The length of the holding strip (7) must be sufficient to fit all thigh perimeters in the area of elastic extension of the material of the holding strip (7). For example, the harness 1 adaptable to the perimeters of leg from 40 to 60 cm, has a leg circumference of about 38 cm, a thigh support 36 cm long and 6 cm wide. The headband has a length of 34 cm. The harness 2 adaptable to the perimeter of the thighs from 50 to 70 cm, has a turn of thigh about 46 cm, a leg support 42 cm long for a width of 6 cm. The headband has a length of 38 cm

    Selon un second mode de réalisation, le tour de cuisse (2) de portance est bien supérieur au périmètre de la cuisse (5) et comporte à l'intérieur vers la cuisse (5) un élément d'épaisseur (37) venant en contact élastique serré avec la cuisse (5) assurant ainsi un bon maintien du support de cuisse (3), sans modifier la longueur de l'élément de portance. L'élément d'épaisseur (37) se fixe sur la partie intérieure du tour de cuisse (2) et est constitué d'une enveloppe remplie d'air (38) à pression réglable à l'aide d'une pompe intégrée (39) (fig 15) et/ou d'une bande de mousse (40) (fig 16) Cette enveloppe d'air (38) et/ou cette bande de mousse (40) de par leur qualité élastique de rémanence s'adaptent à la morphologie de l'utilisateur, et maintiennent automatiquement le support de cuisse (3) de portance en bonne place sur la cuisse (5) du porteur.According to a second embodiment, the thigh circumference (2) of lift is well greater than the perimeter of the thigh (5) and has on the inside towards the thigh (5) an element of thickness (37) coming into tight elastic contact with the thigh (5) thus ensuring a good maintaining the thigh support (3) without changing the length of the lift element. The thickness element (37) is fixed on the inner part of the leg circumference (2) and consists of an air-filled envelope (38) with adjustable pressure using an integrated pump (39) (fig. 15) and / or a foam strip (40) (FIG. 16). This air envelope (38) and / or this strip of foam (40) by their elastic quality of remanence adapt to the morphology of the user, and automatically maintain the thigh support (3) in good place on the thigh (5) of the wearer.

    Selon un troisième mode de réalisation (fig 17), le tour de cuisse (2) comporte une partie de longueur variable (41)grâce à une partie élastique en parallèle à l'élément de portance qui réduit la longueur de la sangle de liaison (4) reliant le support de cuisse (3) à la ceinture (1).According to a third embodiment (FIG. 17), the thigh loop (2) comprises a part of variable length (41) thanks to an elastic part parallel to the element of lift which reduces the length of the connecting strap (4) connecting the thigh support (3) to the belt (1).

    Au moins une sangle de liaison (4) du tour de cuisse (2) comporte une partie de longueur variable (41) se repliant en accordéon grâce à une partie élastique de tension accrochée en parallèle avec ladite partie de longueur variable situé au-delà du point limite (12). Cet élément élastique rétrécit la longueur de la sangle de liaison (4) qui alors se plisse si la taille de la cuisse est petite, mais garde une réserve et peut s'allonger pour les cuisses de taille importante. Il est fixé à l'extérieur de la sangle ou intégré dans la fibre de la sangle ou la sangle comporte un élément de portance fait d'une matière creuse (sangle tubulaire par exemple) dans laquelle est placée au préalable une bande élastique, qui par sa réserve élastique ajuste et positionne automatiquement les éléments de portance aux cuisses de l'utilisateur en faisant des bourrelets et des ondulations dans la sangle. En cas de chute du porteur du harnais, le support de cuisse (3) qui au repos était maintenu en bonne position grâce à la partie de la sangle ondulée par l'élastique se tend et résiste, sans modifier la longueur de l'élément de portance en charge.At least one connecting strap (4) of the thigh circumference (2) comprises a portion of variable length (41) folding accordion thanks to an elastic tension part hung in parallel with said variable length portion beyond the limit point (12). This elastic element narrows the length of the connecting strap (4) which then folds if the size of the thigh is small, but keeps a reserve and can lie down for the thighs of large size. It is attached to the outside of the strap or integrated into the fiber of the strap or the strap has a lift element made of a hollow material (tubular strap by example) in which is placed beforehand an elastic band, which by its reserve elastic adjusts and automatically positions the lift elements at the thighs of the user by making beads and corrugations in the strap. In the event of a fall wearer of the harness, the thigh support (3) which at rest was kept in a good position thanks to the part of the strap waved by the elastic stretches and resists, without modifying the length of the lift element under load.
