Description

Domaine TechniqueTechnical area

La présente invention concerne généralement un harnais d'antichute.The present invention generally relates to a fall arrest harness.

Etat de la techniqueState of the art

Comme on le sait, le harnais est, de manière générale, un Equipement de Protection Individuelle (EPI) destiné à la prévention et à la gestion de la chute des travailleurs en hauteur, alpinistes et autres grimpeurs dans le cadre de leur activité professionnelle ou sportive. Dans le milieu professionnel, on distingue généralement deux types de harnais : le harnais pour travaux en suspension (cuissard) et le harnais d'antichute (dit également harnais complet).As is known, the harness is, in general, a Personal Protective Equipment (PPE) intended for the prevention and management of the fall of workers at height, climbers and other climbers in the context of their professional or sporting activity . In the workplace, there are usually two types of harnesses: the harness for suspension work (shorts) and the fall arrest harness (also called complete harness).

Le harnais cuissard comprend typiquement une ceinture et une paire de sangles de cuisses reliées à la ceinture au niveau du centre de gravité, ces sangles faisant le tour des cuisses. Le point d'encordement est situé au niveau du centre de gravité, à la jonction de la ceinture et des sangles de cuisses. Ce type de harnais est généralement utilisé pour les loisirs (escalade, alpinisme, descente en rappel, canyoning, spéléologie). Avec des bretelles et un point d'ancrage dorsal, il est également utilisé pour les travaux en suspension.The sit harness typically includes a belt and a pair of thigh straps connected to the waist at the center of gravity, these straps running around the thighs. The tie-in point is located at the center of gravity, at the junction of the belt and thigh straps. This type of harness is generally used for recreation (climbing, mountaineering, abseiling, canyoning, caving). With shoulder straps and a dorsal anchor, it is also used for suspension work.

Le harnais complet d'antichute est conçu pour retenir le torse et la région pelvienne des travailleurs et à les supporter pendant et après une chute, conformément aux exigences de la Norme EN 361. Il est largement utilisé dans le milieu professionnel, notamment par les travailleurs spécialisés pour les travaux en hauteur. Le point d'accrochage est situé plus haut que le centre de gravité (torse ou dos), ce qui évite les risques de retournement.The full fall arrest harness is designed to hold the torso and pelvic region of workers and to support them during and after a fall, in accordance with the requirements of EN 361. It is widely used in the workplace, particularly by workers. specialized for work at height. The attachment point is located higher than the center of gravity (torso or back), which avoids the risk of reversal.

Un modèle bien connu de harnais complet est illustré aux Figures 1 et 2. Comme illustré, le harnais 10 a une structure intégrale en forme de huit réalisée à partir d'une bande flexible de haute résistance mécanique. On distingue plusieurs portions de sangles, notamment : en partie supérieure, une paire de bretelles 12 passant sur les épaules et se croisant dans le dos ; et en partie inférieure, une paire de sangle de cuisses 14. Une plaque de positionnement 16 maintient un positionnement relatif entre les bretelles dans le dos de l'utilisateur, à leur point de croisement. En partie inférieure, un sanglon 18 permet de limiter l'écartement entre les sangles de cuisses 14. Un point d'accrochage dorsal en acier (non montré) se trouve au niveau de la plaque 16. A l'avant, l'encordage se fait au niveau d'une paire de points d'ancrage sternaux 20, dans lesquels on passe un mousqueton 22.A well-known full body harness is illustrated in Figures 1 and 2. As illustrated, the harness 10 has an integral eight-shaped structure made from a flexible strip of high strength. There are several portions of straps, in particular: in the upper part, a pair of suspenders 12 passing over shoulders and crossing each other in the back; and in the lower part, a pair of thigh straps 14. A positioning plate 16 maintains a relative positioning between the straps in the user's back, at their point of intersection. In the lower part, a sanglon 18 makes it possible to limit the spacing between the thigh straps 14. A dorsal attachment point made of steel (not shown) is at the level of the plate 16. At the front, the binding is made at a pair of sternal anchor points 20, in which a carabiner 22 is passed.

Ce type de harnais est plus confortable lors de la marche que les harnais cuissards. Néanmoins, en cas de chute, il devient vite désagréable. On a en effet observé que le harnais complet conventionnel illustré aux Figs.1 et 2 exerce de fortes pressions sur les parties latérales antérieures de la cage thoracique et surtout dans la région inguinale, où il comprime fortement les artère fémorales, nécessitant de récupérer la personne en suspension dans un court délai (moins de 15 minutes). Dans la pratique, on observe également que l'utilisateur perd souvent du temps à identifier les différentes parties du harnais avant de l'enfiler, car les sangles ont tendance à s'emmêler.This type of harness is more comfortable when walking than harnesses thighs. However, in case of a fall, it quickly becomes unpleasant. It has indeed been observed that the conventional full-body harness illustrated in FIGS. 1 and 2 exerts strong pressure on the anterior lateral parts of the thoracic cage and especially in the inguinal region, where it strongly compresses the femoral arteries, requiring recovery of the person. Suspended in a short time (less than 15 minutes). In practice, it is also observed that the user often loses time identifying the different parts of the harness before putting on, because the straps tend to get tangled.

Objet de l'inventionObject of the invention

L'objet de la présente invention est de proposer un harnais d'antichute amélioré, qui, en suspension, minimise les efforts de compression au niveau de la région inguinale.The object of the present invention is to provide an improved fall arrest harness, which, in suspension, minimizes compressive forces at the inguinal region.

Conformément à l'invention, cet objectif est atteint par un harnais d'anti-chute selon la revendication 1.According to the invention, this objective is achieved by an anti-fall harness according to claim 1.

Description générale de l'inventionGeneral description of the invention

Selon l'invention, un harnais d'antichute comprend :

  • une partie supérieure comprenant une paire de sangles bretelles passant sur le torse de l'utilisateur et un point d'accrochage ; et
  • une partie inférieure comprenant une paire de sangles inférieures entourant chacune une cuisse respective de l'utilisateur, chacune desdites sangles inférieures étant fixement liée à ladite partie supérieure dans une zone de jonction coïncidant essentiellement avec la région antérieure du flanc proximal de la cuisse entourée.
According to the invention, a fall arrest harness comprises:
  • an upper portion comprising a pair of straps straps passing over the torso of the user and a point of attachment; and
  • a lower part comprising a pair of lower straps surrounding each having a respective thigh of the user, each of said lower straps being fixedly attached to said upper portion in a juncture zone substantially coinciding with the anterior region of the proximal flank of the surrounding thigh.

La présente invention propose donc un harnais d'antichute complet, dont les sangles inférieures de cuisses sont ancrées fixement (par ex. cousues) sur la partie supérieure, dans la région de la partie antérieure latérale du torse de l'utilisateur.The present invention therefore provides a complete fall arrest harness, the lower thigh straps of which are fixedly anchored (eg sewn) on the upper part in the region of the lateral front part of the torso of the user.

Puisque les sangles inférieures sont fermement fixées sur la partie supérieure, elles ne peuvent pas, en cas de chute, se resserrer autour des cuisses et dans les plis de l'aine, comme se serait le cas avec un harnais complet du type de la Fig.1, où il n'y a pas de maintien des sangles de cuisses. De plus, l'ancrage des sangles inférieures dans la zone de jonction sélectionnée provoque, en suspension par un point d'ancrage sternal, une distribution des efforts telle que la majorité des efforts sont repris par les sangles inférieures au niveau des fesses. La poitrine est également moins comprimée. L'utilisateur quant à lui à l'impression d'être plus assis, ce qui accroît encore le sentiment de confort.Since the lower straps are firmly fixed on the upper part, they can not, in the event of a fall, tighten around the thighs and in the folds of the groin, as would be the case with a complete harness of the type of FIG. .1, where there is no maintenance of thigh straps. In addition, the anchoring of the lower straps in the selected junction area causes, suspended by a sternal anchor point, a distribution of forces such that the majority of efforts are taken up by the lower straps at the buttocks. The chest is also less compressed. The user feels more seated, which increases the feeling of comfort.

Les dispositions constructives du harnais selon l'invention entraînent donc une répartition des efforts au niveau de la zone pelvienne telle que les efforts les plus importants sont reportés vers la zone postérieure, au niveau des fesses, alors que la partie antérieure (cuisses et région inguinale) est moins sollicitée. En d'autres termes, les efforts de compression dans la région inguinale, et donc sur les artères fémorales, sont minimisés, ce qui procure un plus grand confort dans le temps.The constructive arrangements of the harness according to the invention therefore lead to a distribution of forces in the pelvic area such that the greatest efforts are transferred to the posterior area, at the buttocks, while the anterior part (thighs and inguinal region ) is less solicited. In other words, the compression efforts in the inguinal region, and thus on the femoral arteries, are minimized, which provides greater comfort over time.

Des variantes préférées du harnais selon l'invention sont décrites dans les revendications dépendantes 2 à 11.Preferred variants of the harness according to the invention are described in dependent claims 2 to 11.

Description détaillée d'un mode de réalisation préféréDetailed description of a preferred embodiment

La Fig.3 illustre un mode de réalisation préféré d'un harnais d'antichute complet 50 selon l'invention. Il est muni, en partie supérieure, d'une paire de sangles bretelles 52. Chaque sangle-bretelle 52 comprend une partie frontale 54 s'étendant sur la poitrine de l'utilisateur et passant sur une épaule; une partie dorsale 56 s'étendant en biais de l'épaule jusqu'au flanc opposé; et une partie terminale 58 entourant le flanc de l'utilisateur pour revenir sur la partie antérieure du torse (voir aussi Fig.4). Chacune des parties frontales 54 des sangles-bretelles 52 est fixement liée, en sa partie inférieure, aux parties terminales 58 de l'autre sangle-bretelle. Par "fixement liée", on entend une liaison non mobile et solide, qui peut être obtenue par exemple par couture.Fig.3 illustrates a preferred embodiment of a full fall arrest harness 50 according to the invention. It is provided, at the top, with a pair of shoulder straps 52. Each strap-strap 52 comprises a front portion 54 extending on the chest of the user and passing on a shoulder; a dorsal portion 56 extending obliquely from the shoulder to the opposite flank; and an end portion 58 surrounding the user's side to return to the anterior portion of the torso (see also Fig.4). Each of the front portions 54 of the straps-braces 52 is fixedly attached, in its lower part, to the end portions 58 of the other strap-strap. By "fixedly bonded" is meant a non-movable and solid connection, which can be obtained for example by sewing.

De préférence, les sangles-bretelles 52 sont réglables en longueur au moyen de boucles de réglage 60 conventionnelles. Dans la présente variante, la partie frontale 54, la partie dorsale 56 et la partie terminale 58 de chaque bretelle 52 sont en fait une même bande textile. Alternativement, il peut s'agir de différentes bandes textiles jointes par couture. Les bandes textiles utilisées pour le harnais sont préférablement en filaments vierges de grande tenacité ou en fibres synthétiques multifilament (par ex. polyamide) adaptées à cette utilisation.Preferably, the shoulder straps 52 are adjustable in length by means of conventional adjustment loops 60. In the present variant, the front portion 54, the dorsal portion 56 and the end portion 58 of each strap 52 are in fact the same textile strip. Alternatively, it may be different textile strips joined by stitching. The textile strips used for the harness are preferably virgin filaments of high tenacity or multifilament synthetic fibers (eg polyamide) adapted to this use.

Comme on peut le voir sur les Figs. 3 et 4, la partie terminale 58 enveloppe le flanc de l'utilisateur et revient sur sa partie antérieure de manière sensiblement horizontale, dans la région sous thoracique (entre le bas des côtes et le bassin). Les extrémités des parties terminales 58 sont pourvues chacune d'un élément d'accrochage sternal, prenant la forme d'une boucle textile 62.As can be seen in Figs. 3 and 4, the end portion 58 envelops the user's side and returns to its front part so as to substantially horizontal, in the thoracic region (between the lower ribs and the pelvis). The ends of the end portions 58 are each provided with a sternal anchoring element, in the form of a textile loop 62.

Un point d'accrochage dorsal, réalisé en tant que boucle textile 66, est situé environ au point de croisement des bretelles 52.A dorsal attachment point, made as a textile loop 66, is located approximately at the point of intersection of the shoulder straps 52.

La partie inférieure du harnais 50 comprend une paire de sangles inférieures 68 entourant chacune une cuisse respective de l'utilisateur. Comme on peut le voir, chaque sangle inférieure 68 est fixement liée à la partie supérieure dans une zone de jonction coïncidant essentiellement avec la région antérieure du flanc (région sous thoracique latérale) proximal de la cuisse entourée. Dans la présente variante, cela est obtenu par la fixation (couture) des sangles inférieures 68 aux parties terminales 58 des bretelles 52 à l'endroit où elles passent sur la partie latérale (latérale antérieure) du flanc de l'utilisateur. Ainsi, chaque sangle inférieure 68 est cousue sur une portion de sangle qui relie le point d'accrochage dorsal 66 aux éléments d'accrochage sternaux 62. Préférablement, les deux extrémités de chaque sangle inférieure 68 sont cousues sensiblement au même endroit sur la partie terminale 58.The lower portion of the harness 50 includes a pair of lower straps 68 each surrounding a respective thigh of the user. As can be seen, each lower strap 68 is fixedly bonded to the upper portion in a juncture zone substantially coinciding with the proximal flank (proximal thoracic region) proximal region of the surrounding thigh. In the present variant, this is achieved by attaching (sewing) the lower straps 68 to the end portions 58 of the straps 52 where they pass over the lateral (forward lateral) portion of the user's side. Thus, each lower strap 68 is sewn onto a portion of strap that connects the dorsal attachment point 66 to the sternal fasteners 62. Preferably, both ends of each lower strap 68 are sewn substantially at the same location on the end portion. 58.

On appréciera que les sangles inférieures 68 sont destinées à supporter, en suspension, les fesses de l'utilisateur. Ainsi, les sangles inférieures 68 passent sur les parties avant et intérieures de la cuisse (ne l'entourant en fait qu'en partie), pour ensuite remonter en passant sur la fesse, de préférence en partie inférieure et/ou médiane. La partie sous fessière 70 de chaque sangle inférieure peut être élargie et rembourrée pour mieux répartir les efforts. Afin de faciliter la mise en place du harnais, les sangles inférieures 68 sont avantageusement équipées de boucles de fermeture automatiques 72. Un sanglon 74 solidarise les deux sangles inférieures 68 afin de limiter leur écartement et donc de les maintenir dans la position souhaitée.It will be appreciated that the lower straps 68 are intended to support, in suspension, the buttocks of the user. Thus, the lower straps 68 pass over the front and inner parts of the thigh (only partially surrounding it), and then go up through the buttock, preferably in the lower and / or median. The gluteal portion 70 of each lower strap can be enlarged and padded to better distribute the efforts. In order to facilitate the installation of the harness, the lower straps 68 are advantageously equipped with automatic closure loops 72. A strap 74 secures the two lower straps 68 in order to limit their spacing and thus to maintain them in the desired position.

De par sa conception, le présent harnais 50 occasionne un minimum d'entrave pour le travailleur/utilisateur dans ses déplacements dans le plan horizontal et vertical; et en cas de chute, il répartit la grande majorité des efforts sur les fesses. Cela est obtenu par la disposition particulière des sangles du présent harnais 50, et notamment par l'ancrage particulier des sangles inférieures 68 à la partie supérieure.By design, the present harness 50 causes a minimum of hindrance for the worker / user in its movements in the horizontal and vertical plane; and in case of a fall, he spreads the vast majority of efforts on the buttocks. This is obtained by the particular arrangement of the straps of the present harness 50, and in particular by the particular anchoring of the lower straps 68 to the upper part.

Comme on le voit sur la Fig.5, lorsque l'utilisateur est en suspension dans le harnais 50, les sangles inférieures 68 passent par le milieu des fesses, qui sont alors sollicitées en compression.As seen in Fig.5, when the user is suspended in the harness 50, the lower straps 68 pass through the middle of the buttocks, which are then urged into compression.

On notera qu'il existe un angle β relativement fermé entre les parties des sangles inférieures qui passent sur l'avant des cuisses (voir Fig.4). De préférence, cet angle β est de l'ordre de 30 à 40°, et est obtenu par couture de chaque sangle inférieure 68 sur la partie terminale respective avec un angle δ de 70 à 75°. En suspension (Fig.5), l'angle β tend à se réduire.Note that there is a relatively closed angle β between the parts of the lower straps that pass on the front of the thighs (see Fig.4). Preferably, this angle β is of the order of 30 to 40 °, and is obtained by sewing each lower strap 68 on the respective end portion with an angle δ of 70 to 75 °. In suspension (Fig.5), the angle β tends to be reduced.

On appréciera que ces dispositions constructives créent une répartition des efforts différente entre la partie postérieure (plus importants) et antérieure de l'utilisateur (plus faibles). Il en résulte une faible sollicitation de l'aine et des artères fémorales, ce qui permet de concentrer l'essentiel des efforts de compression dans les zones sous fessières. Par ailleurs, la répartition plus faible des efforts sur la partie antérieure entraîne une moindre compression de la poitrine de l'utilisateur.It will be appreciated that these constructive arrangements create a different distribution of efforts between the posterior (larger) and anterior (lower) user. This results in a low solicitation of the groin and femoral arteries, which allows to concentrate most of the compression efforts in the gluteal areas. In addition, the lower distribution of forces on the front part results in less compression of the user's chest.

A titre comparatif, dans un harnais complet traditionnel 10 tel qu'illustré aux Figs.1 et 2, il existe un angle α entre les sangles de cuisses 14 de l'ordre de 65°. En suspension, les sangles de cuisses 14 (qui ne sont pas fixes par rapport à la partie haute) tendent à glisser latéralement à cause de cet angle α relativement ouvert et pénètrent dans les plis de l'aine, comprimant fortement les artères fémorales.By way of comparison, in a traditional full-body harness 10 as illustrated in FIGS. 1 and 2, there is an angle α between the thigh straps 14 of the order of 65 °. In suspension, the thigh straps 14 (which are not fixed relative to the upper part) tend to slide laterally because of this relatively open angle α and penetrate the folds of the groin, strongly compressing the femoral arteries.

Sur la Fig.5 on notera encore qu'en suspension, la partie de la sangle inférieure 68 qui remonte vers la poitrine sur la partie extérieure de la fesse est alignée avec la partie terminale 58 à laquelle elle est ancrée.In Fig.5 it will be further noted that in suspension, the portion of the lower strap 68 which rises towards the chest on the outer portion of the buttock is aligned with the end portion 58 to which it is anchored.

Comme illustré sur la Fig.3, un dosseret 74 de forme triangulaire est solidaire des sangles dorsales 56, qui le bordent. Il s'étend donc du point de croisement des sangles dorsales 56 jusqu'au bas des côtes. Le dosseret 74 permet de maintenir la position précise des deux sangles dorsale 56 dans le dos tout en supportant la zone du bas des côtes. Par ailleurs, il maintient le harnais 50 en forme pour faciliter la compréhension de mise en place du harnais par l'utilisateur. Les boucles de réglage 60 permettent d'ajuster la position du dosseret 74 pour que ses sommets inférieurs coïncident avec le bas des côtes.As illustrated in Fig.3, a backrest 74 of triangular shape is integral with the back straps 56, which border. It extends from the point of intersection of the dorsal straps 56 to the bottom of the ribs. The backsplash 74 allows to maintain the precise position of the two dorsal straps 56 in the back while supporting the area of the bottom of the ribs. Moreover, it keeps the harness 50 in shape to facilitate the user's understanding of positioning the harness. The adjustment loops 60 make it possible to adjust the position of the backrest 74 so that its lower vertices coincide with the bottom of the ribs.

Les signes de référence 76 et 78 indiquent respectivement des bandes élastiques d'ajustement du torse et des cuisses. Deux sangles porte-matériel 80 peuvent être prévues sur la partie terminale 58 des bretelles 52, vers la région postérieure du flanc (en arrière des zones de couture des partie frontale et sangles inférieures).The reference signs 76 and 78 respectively indicate elastic bands of adjustment of the torso and the thighs. Two material straps 80 may be provided on the end portion 58 of the straps 52, towards the posterior region of the sidewall (behind the seam areas of the front and lower straps).

Le présent harnais 50 constitue donc un harnais d'antichute complet qui arrête l'utilisateur en cas de chute et le maintient après la chute dans une position qui sollicite moins les artères fémorales que les harnais traditionnels. Dans la pratique, pour un même angle de suspension, l'utilisateur a le sentiment d'être plus assis, tout en minimisant les efforts de compression dans la zone inguinale, ceux-ci étant majoritairement reportés dans la région sous fessière.The present harness 50 is therefore a complete fall arrest harness that stops the user in the event of a fall and maintains it after the fall in a position that requires less femoral arteries than traditional harnesses. In practice, for the same angle of suspension, the user has the feeling of being seated, while minimizing compression efforts in the inguinal area, the latter being mainly reported in the gluteal region.
