Abstract
Description
Dans le domaine des travailleurs en hauteur, des harnais de sécurité sont utilisés afin de retenir l'utilisateur en cas de chute. Ces harnais sont reliés à une structure par un élément de liaison. Les harnais utilisés aujourd'hui sont principalement constitués de sangles rigides. In the field of workers at height, safety harnesses are used to restrain the user in the event of a fall. These harnesses are connected to a structure by a connecting element. The harnesses used today are mainly made of rigid straps.
La personne ayant chuté se retrouve suspendue dans son harnais. Son corps pèse de tout son poids sur les sangles passant entre ses cuisses et les sangles rigides, malgré leur relative largeur (40 mm min selon la norme qui régit leur conception), forment des points de compression. Les points les plus critiques se situent à l'aine et pressent l'artère fémorale. Le coeur continue d'envoyer du sang à travers tout le corps. Le sang qui arrive aux extrémités des membres inférieurs doit revenir vers le coeur contre l'action de la gravité. Chez le sujet normal, c'est la contraction des muscles de la jambe et surtout du mollet qui remplit ce travail de pompe. Chez le sujet en inertie ce retour veineux est perturbé. Ce phénomène est d'autant plus gêné par le harnais, auquel s'ajoute l'épuisement, l'hypothermie, etc... The fallen person is suspended in his harness. His body weighs all his weight on the straps passing between his thighs and the rigid straps, despite their relative width (40 mm min according to the standard that governs their design), form points of compression. The most critical points are in the groin and press the femoral artery. The heart continues to send blood throughout the body. The blood that reaches the extremities of the lower limbs must return to the heart against the action of gravity. In the normal subject, it is the contraction of the muscles of the leg and especially of the calf which fills this work of pump. In the subject inertia this venous return is disturbed. This phenomenon is all the more hampered by the harness, to which is added exhaustion, hypothermia, etc ...
Le système veineux des jambes peut contenir une grande quantité de sang qui ne participera donc plus à la circulation artérielle. Cela réalise une perte de sang efficace comme dans une hémorragie. Dans des conditions de fatigue normale, avec un environnement tempéré, le temps d'attente moyen est d'environ 30 minutes. Une solution connue à ce jour est le transfert du poids de la personne sur ses pieds, par l'attachement de pédales directement à son point d'ancrage. The venous system of the legs may contain a large amount of blood that will no longer participate in the arterial circulation. This achieves an effective blood loss as in a hemorrhage. Under normal fatigue conditions, with a temperate environment, the average waiting time is approximately 30 minutes. A known solution to date is the transfer of the weight of the person on his feet, by the attachment of pedals directly to his anchor.
Le dispositif se fixe sur le harnais, prêt à l'emploi. C'est une solution qui présente le risque d'être arrachée, de gêner l'utilisateur dans ses déplacements et travaux normaux. Elle nécessite de plus 5 un niveau de formation et de conscience élevés. The device is fixed on the harness, ready to use. It is a solution that presents the risk of being torn off, to hinder the user in his travels and normal work. It also requires a high level of training and awareness.
L'invention pallie ces inconvénients. The invention overcomes these disadvantages.
Elle a pour objet un harnais d'antichute 10 contenant une sangle de retenue d'une personne porteuse du harnais. Un coussin gonflable est disposé de manière à être interposé entre la personne et la sangle et il est prévu un dispositif de gonflage du coussin. It relates to a fall arrest harness 10 containing a retaining strap of a person wearing a harness. An airbag is arranged to be interposed between the person and the strap and there is provided a device for inflating the cushion.
15 Lorsque la personne a chuté et attend du secours, elle peut actionner le dispositif de gonflage, par exemple au moyen d'une poignée à tirer ou d'un bouton coup de poing ou de tout autre mécanisme de déclenchement manuel de sécurité. Le retour veineux est 20 ainsi rendu impossible. When the person has fallen and is waiting for help, he can operate the inflation device, for example by means of a pull handle or a punch button or any other manual safety release mechanism. Venous return is thus rendered impossible.
Le coussin est fixé au reste du harnais, de préférence aux sangles du harnais destinées à supporter ou retenir la personne par les cuisses, le coussin étant 25 à l'intérieur du harnais, c'est à dire du côté de la sangle tournée vers la cuisse de la personne. The cushion is attached to the rest of the harness, preferably to the harness straps for supporting or holding the person by the thighs, the cushion being inside the harness, ie on the side of the strap facing the body. thigh of the person.
Suivant une autre caractéristique, le dispositif de gonflage du coussin d'air peut être 30 actionné par un mécanisme de détection de chute ou par un mécanisme de détection d'impact. La circulation veineuse est ainsi rétablie même si la personne qui a chuté est inconsciente. According to another feature, the airbag inflator may be actuated by a fall detection mechanism or by an impact sensing mechanism. The venous circulation is thus restored even if the person who has fallen is unconscious.
De préférence, le coussin d'air gonflable a la forme d'une culotte destinée à être portée par la personne ou d'un pantalon en sorte que les pressions induites par le harnais sont redistribuées sur une 5 surface plus large, notamment autour de l'aine. Preferably, the inflatable airbag is in the form of pants to be worn by the person or pants so that the pressures induced by the harness are redistributed over a wider area, particularly around the body. 'groin.
Suivant un mode de réalisation particulièrement utile, la partie du coussin d'air destinée à venir en regard des parties génitales n'est pas gonflable. On 10 empêche ainsi qu'il ne s'applique sous l'effet du coussin des forces trop grandes de pression à ces parties qui pourraient les blesser. Le coussin d'air peut alors être constitué de pièces différentes jointes entre elles, celles en regard des parties génitales étant par rapport 15 aux autres et le dispositif de gonflage ne s'appliquant qu'aux autres parties du coussin d'air. Le coussin peut aussi ne pas avoir de partie en regard des parties génitales. According to a particularly useful embodiment, the portion of the air cushion intended to come into contact with the genitals is not inflatable. It is thus prevented from being applied under the effect of the cushion of excessive forces of pressure to these parts which could injure them. The air cushion can then consist of different parts joined together, those facing the genital parts being relative to each other and the inflation device applying to other parts of the air cushion. The cushion may also have no part opposite the genitals.
20 Le coussin peut être en une matière textile, telle que polyamide, polyester, fibres aramide ou méta-aramides revêtues, polypropylène ou polyéthylène revêtu. Les couches supérieures pourront être constituées de matériau anti feu tel que le Nomex. Il peut être 25 constitué de différentes couches de matériaux répondants aux fonctions successives d'étanchéité, de résistance à l'abrasion et au percement, de répartition des efforts. The cushion may be of a textile material, such as polyamide, polyester, aramid fibers or coated meta-aramids, polypropylene or coated polyethylene. The upper layers may consist of fireproof material such as Nomex. It may consist of different layers of materials responding to successive functions of sealing, resistance to abrasion and piercing, distribution of forces.
Suivant un mode de réalisation, le coussin 30 comporte un indicateur d'utilisation. L'utilisateur, avant d'enfiler son équipement avant une journée de travail, voit d'un coup d'œil si le système a été percuté, au moyen d'un déploiement de drapeau ou d'une partie de textile de couleur différente de l'extérieur du système rendue visible lors du gonflage. According to one embodiment, the cushion 30 includes an indicator of use. The user, before putting on his equipment before a working day, sees at a glance whether the system has been hit, by means of a flag deployment or a part of a textile of a color different from the outside of the system made visible during inflation.
Il est enfin prévu de préférence une soupape de dégonflage du coussin pouvant être actionnée par la personne, qui peut ainsi dégonfler le coussin s'il la serre trop. Finally, it is preferably provided a deflation valve of the cushion can be actuated by the person, who can deflate the cushion if it squeezes too much.
L'invention vise enfin un coussin d'air gonflable en forme d'une culotte et notamment constitué de pièces jointes différentes dont l'une d'entre elles, étanche par rapport aux autres, est destinée à se retrouver en regard des parties génitales de celui qui porte le culotte et n'est pas gonflable. The invention finally relates to an inflatable air cushion in the form of a panty and in particular consisting of different attachments, one of which, sealed with respect to the others, is intended to end up facing the genitals of the one who wears the pants and is not inflatable.
Au dessin annexé, donné uniquement à titre d'exemple : les Figures 1 et 2 représentent un harnais d'antichute suivant l'invention, le coussin étant gonflé à la Figure 2 alors qu'il ne l'est pas à la Figure 1 et la Figure 3 représente une variante d'un harnais suivant l'invention. In the accompanying drawing, given solely by way of example: FIGS. 1 and 2 show a fall arrest harness according to the invention, the cushion being inflated in FIG. 2 whereas it is not inflated in FIG. Figure 3 shows a variant of a harness according to the invention.
Le harnais d'antichute représenté aux Figures 1 et 2 comprend des sangles 1 de retenue d'une personne. Certaines de ces sangles s'appliquent indirectement sur les cuisses de la personne, tandis que d'autres sangles supérieures s'appliquent directement sur le corps de la personne. Les sangles supérieures sont reliées par un élément de liaison, non représenté, à une structure fixe. The fall arrest harness shown in Figures 1 and 2 includes straps 1 for retaining a person. Some of these straps apply indirectly to the person's thighs, while other top straps apply directly to the person's body. The upper straps are connected by a connecting element, not shown, to a fixed structure.
Entre les sangles 1, s'appliquant aux cuisses, et les cuisses de la personne portant le harnais, est interposé un coussin d'air 2 gonflable par un dispositif 3 de gonflage et pouvant être dégonflé par une soupape 4 de dégonflage. Le coussin d'air a la forme d'une culotte. Lorsque le coussin d'air est gonflé, comme représenté à la Figure 2, un drapeau 5 apparaît latéralement et indique que le coussin d'air est gonflé. Between the straps 1, applying to the thighs, and the thighs of the person wearing the harness, is interposed an inflatable air cushion 2 by an inflation device 3 and can be deflated by a deflation valve 4. The air cushion is shaped like a pant. When the air bag is inflated, as shown in Figure 2, a flag 5 appears laterally and indicates that the air bag is inflated.
Le dispositif de gonflage 3 peut être actionné par la personne ou peut être actionné automatiquement par un mécanisme de détection de chute ou par un mécanisme de détection d'impact qui ne sont pas représentés. The inflation device 3 may be actuated by the person or may be operated automatically by a fall detection mechanism or by an impact detection mechanism which is not shown.
A la Figure 3, le coussin d'air a la forme d'un pantalon 6 qui, en regard des parties génitales de la personne qui le porte, a une partie 7 étanche vis à vis du reste du coussin d'air 6 et ne se gonflant pas. In Figure 3, the air cushion is in the form of trousers 6 which, facing the genitals of the person wearing it, has a part 7 sealed with respect to the rest of the air cushion 6 and not swelling.
