Abstract
Description
L'invention a essentiellement pour objet un ensemble formant combinaison de sécurité pour les sports de la neige prévu notamment pour assurer une protection contre les avalanches. The subject of the invention is essentially an assembly forming a safety suit for snow sports intended in particular to provide protection against avalanches.
L'ensemble proposé par l'invention vise en particulier à assurer la sécurité des utilisateurs adeptes du ski hors piste ou en danger sur piste. The assembly proposed by the invention aims in particular to ensure the safety of users of off-piste skiing or in danger on the piste.
Selon l'invention, l'ensemble proposé comporte un certain nombre de poches gonflées au moyen d'un gaz qui sont solidaires de la poitrine, du dos de l'utilisateur, d'un capuchon recouvrant sa tête et de fourreaux entourant ses membres supérieurs et inférieurs, des moyens étant prévus pour gonfler lesdites poches lesquels sont associés à une commande manuelle. According to the invention, the proposed assembly includes a number of pockets inflated by means of a gas which are integral with the chest, the back of the user, a cap covering his head and sheaths surrounding his upper limbs and lower, means being provided for inflating said pockets which are associated with manual control.
Avec un tel équipement, étant donné que l'utilisateur dispose pour réagir de quelques secondes après le déclenchement d'une avalanche avant d'être atteint par celle-ci, il a la possibilité d'actionner la commande manuelle et de gonfler sa combinaison. With such equipment, since the user has a few seconds to react after the triggering of an avalanche before being reached by it, he has the possibility of activating the manual control and inflating his suit.
Le phénomène de ségrégation est bien connu dans le domaine de la technique selon lequel des corps de densité plus élevée disposés dans un milieu fluide composé de corps de densité moindre se présentant sous la forme de particules, ont tendance à s'enfoncer dans ce milieu par gravité alors que des corps de densité moindre ont tendance à surnager. The phenomenon of segregation is well known in the field of the technique according to which bodies of higher density disposed in a fluid medium composed of bodies of lower density in the form of particles, tend to sink into this medium by gravity while bodies of lower density tend to float.
Des expériences ont été faites dans des avalanches avec un ballon de football, un ballon d'une soixantaine de centimètres de diamètre et un cascadeur muni d'une combinaison selon l'invention et il s'est avéré que les ballons comme le cascadeur avaient tendance à rester en surface dans la neige de l'avalanche au lieu d'y être ensevelis. Experiments have been made in avalanches with a soccer ball, a ball about sixty centimeters in diameter and a stuntman provided with a suit according to the invention and it has been found that balloons like stuntman tend to remain on the surface in the snow of the avalanche instead of being buried there.
Compte tenu de ce qui précède, le problème posé pour protéger un skieur contre les avalanches consiste à lui donner une "flottabilité" la plus grande possible par rapport à la densité de la neige de l'avalanche. Ce problème est résolu en réduisant sa "densité" par augmentation de son "volume extérieur" comme suggéré plus haut. On notera que tout se produit de façon dynamique. In view of the above, the problem posed to protect a skier against avalanches consists in giving him the greatest possible "buoyancy" in relation to the density of the avalanche snow. This problem is solved by reducing its "density" by increasing its "external volume" as suggested above. Note that everything happens dynamically.
Selon une autre caractéristique de l'invention, le corps de l'utilisateur est revêtu d'un survêtement en matière étanche aux gaz et les poches sont formées sur ledit survêtement sous la forme de parois extérieures étanches dilatables. According to another characteristic of the invention, the user's body is coated with a tracksuit made of gas-tight material and the pockets are formed on said tracksuit in the form of watertight expandable external walls.
Egalement selon l'invention, les parois extérieures sont réalisées, de préférence, en un tissu étanche élastique, plissé ou plié tel que du nylon imprégné de néoprène et les coutures définissant les poches sont rendues étanches au moyen de silicones. Also according to the invention, the outer walls are preferably made of an elastic waterproof fabric, pleated or folded such as nylon impregnated with neoprene and the seams defining the pockets are made waterproof by means of silicones.
I1 a été proposé des combinaisons de sécurité pour motocyclistes (voir notamment FR-A- 2 256 729 et 2 272 615). Ces combinaisons comportent un casque rigide, des bourrelets longitudinaux et des plaques rigides protégeant les coudes et les genoux de l'utilisateur contre des chutes avec glissade sur le sol. Elles ne permettent pas de résoudre le problème posé. Safety suits for motorcyclists have been proposed (see in particular FR-A-2 256 729 and 2 272 615). These combinations include a rigid helmet, longitudinal beads and rigid plates protecting the elbows and knees of the user against falls with slipping on the ground. They do not solve the problem posed.
Dans le domaine de l'automobile, il a été proposé des sacs de protection gonflés comme décrit par exemple dans EP A-61 828 qui décrit un sac protégeant les genoux et le thorax du conducteur après gonflage à une faible pression en 35 à 40 millisecondes. L'application au domaine de la neige n'est aucunement suggérée. In the automotive field, inflated protective bags have been proposed as described, for example, in EP A-61 828 which describes a bag protecting the driver's knees and chest after inflation at low pressure in 35 to 40 milliseconds . Application to the snow domain is in no way suggested.
Ces dispositifs de l'art antérieur sont difficilement transposables dans le domaine intéressant l'invention, à savoir la protection contre les avalanches. These devices of the prior art are difficult to transpose into the field of interest of the invention, namely protection against avalanches.
D'autres caractéristiques et avantages de l'invention apparaîtront dans la description qui va suivre et se réfère aux dessins annexés dans lesquels
- la figure 1 montre schématiquement de face, un ensemble formant combinaison de sécurité pour les sports de la neige selon l'invention ;
- la figure 2 est une vue schématique en coupe partielle de l'ensemble de la figure 1 prise selon la ligne 2-2 montrant la silhouette hachurée de l'utilisateur
- les figures 3 et 4 sont des vues en coupe respectivement selon les lignes 3-3 et 4-4 de la figure 1
- les figures 5 et 6 montrent schématiquement en perspective des plis avantageusement utilisés pour réaliser les parois extérieures de la combinaison représentée aux figures 1 et 2.Other characteristics and advantages of the invention will appear in the description which follows and refers to the appended drawings in which
- Figure 1 shows schematically from the front, an assembly forming a safety suit for snow sports according to the invention;
- Figure 2 is a schematic view in partial section of the assembly of Figure 1 taken along line 2-2 showing the hatched silhouette of the user
- Figures 3 and 4 are sectional views respectively along lines 3-3 and 4-4 of Figure 1
FIGS. 5 and 6 schematically show in perspective folds advantageously used to produce the outer walls of the combination shown in FIGS. 1 and 2.
On a montré à la figure 1 un ensemble formant combinaison de sécurité pour les sports de la neige selon l'invention, désigné par la référence générale 10 comportant un survêtement interne 12, représenté en trait plein, dont une partie 16 recouvre le thorax de l'utilisateur montré en coupe en 14 à la figure 2. A la partie interne recouvrant la poitrine est associée une fermeture à glissière 18. On a montré en 20 une partie recouvrant le dos. La tête représentée schématiquement en 22 est recouverte d'un capuchon dont la paroi interne a été désignée par la référence 24. Des fourreaux 26 recouvrent les membres supérieurs alors que d'autres fourreaux 28 entourent les membres inférieurs comme montré à la figure 1.L'ensemble de la combinaison plaqué contre le corps et formant paroi interne est recouvert, au moins partiellement, par une doublure extérieure reliée à des moyens de gonflage non représentés commandés par une tirette ou moyen d'actionnement analogue (non représenté) disposée dans une poche 30 plaquée sur la paroi externe de la combinaison au niveau du thorax. Le moyen de déclenchement prévu dans la pochette 30 commande un générateur de gaz pour l'ensemble de la combinaison ou des générateurs de gaz synchronisés destinés à gonfler les diverses parties formant poches de celle-ci. FIG. 1 shows an assembly forming a safety suit for snow sports according to the invention, designated by the general reference 10 comprising an internal tracksuit 12, shown in solid lines, a part 16 of which covers the thorax of the the user shown in section at 14 in FIG. 2. The internal part covering the chest is associated with a zipper 18. A part covering the back has been shown at 20. The head shown diagrammatically at 22 is covered with a cap, the internal wall of which has been designated by the reference 24. Sheaths 26 cover the upper limbs while other sheaths 28 surround the lower limbs as shown in FIG. 1.L the whole of the suit pressed against the body and forming an internal wall is covered, at least partially, by an external lining connected to inflation means not shown, controlled by a zipper or similar actuation means (not shown) arranged in a pocket 30 pressed against the external wall of the suit at the level of the thorax. The trigger means provided in the pocket 30 controls a gas generator for the whole of the combination or synchronized gas generators intended to inflate the various parts forming pockets of the latter.
On a montré en trait mixte sur les figures 1 à 4 les parois extérieures de la combinaison après gonflage. The outer walls of the suit after inflation have been shown in phantom in FIGS. 1 to 4.
Comme le montre le dessin, les parties gonflées protègent notamment la tête 22 et le thorax 14, de même que les membres supérieurs et les membres inférieurs qui se trouvent respectivement dans les fourreaux 26 et 28. As the drawing shows, the swollen parts protect in particular the head 22 and the thorax 14, as well as the upper limbs and the lower limbs which are located respectively in the sheaths 26 and 28.
On notera en considérant les figures 3 et 4 que les fourreaux 26 des membres supérieurs se dilatent seulement vers l'extérieur du corps comme montré en 32 sur la figure 3 de façon à permettre aux bras de rester contre la paroi du corps alors que les fourreaux associés aux membres inférieurs 28 se dilatent sous la forme d'un cylindre de section sensiblement circulaire 34. It will be noted by considering Figures 3 and 4 that the sheaths 26 of the upper limbs only expand towards the outside of the body as shown at 32 in Figure 3 so as to allow the arms to remain against the wall of the body while the sheaths associated with the lower limbs 28 expand in the form of a cylinder of substantially circular section 34.
Sur la figure 1, on a montré au moyen de tirets des plis ou fronces qui sont prévus sur la paroi extérieure de la combinaison. Des exemples de plis qu'il est possible d'utiliser sont montrés aux figures 5 et 6. La figure 5 montre des plis plats obtenus par pliage et repassage et la figure 6 montre des plis ronds qui, s'ils sont adjacents, permettent de tripler la zone de surface extérieure qu'ils intéressent. In Figure 1, there are shown by dashes folds or gathers which are provided on the outer wall of the suit. Examples of folds that can be used are shown in Figures 5 and 6. Figure 5 shows flat folds obtained by folding and ironing and Figure 6 shows round folds which, if they are adjacent, allow triple the outside surface area they are interested in.
Le volume des poches gonflées a avantageusement une valeur qui est au moins égale à celle du corps de l'utilisateur et la pression dans les poches est de l'ordre d'au moins 100 à 200 g/cm2. The volume of the inflated bags advantageously has a value which is at least equal to that of the body of the user and the pressure in the bags is of the order of at least 100 to 200 g / cm 2.
Bien entendu, l'invention qui vise essentiellement de protéger l'utilisateur contre les avalanches, peut présenter également des avantages en ce qui concerne sa sécurité dans d'autres domaines des sports de la neige, notamment au tremplin en cas de perte de skis ou en cas de détresse (chute avec fracture ou risque potentiel) dans une région boisée. Dans ces cas, l'utilisateur déclenche le gonflage de sa combinaison dès qu'il a conscience de l'apparition d'un danger. Of course, the invention which essentially aims to protect the user against avalanches, can also have advantages as regards his safety in other fields of snow sports, in particular on the springboard in the event of loss of skis or in the event of distress (fall with fracture or potential risk) in a wooded area. In these cases, the user triggers the inflation of his suit as soon as he is aware of the appearance of a danger.
