Description

SAC A DOS  BACKPACK
[ooi] L'invention concerne un sac à dos. [Ooi] The invention relates to a backpack.
[002] Le déposant connaît des sacs à dos comportant : [002] The applicant knows backpacks comprising:
- compartiment présentant une ouverture, - compartment having an opening,
- un rabat déplaçable entre une position fermée dans laquelle il fait office de chapeau de protection de l'ouverture aux intempéries et une position ouverte dans laquelle il libère l'ouverture,  a flap that can be displaced between a closed position in which it acts as a protective cap of the opening to the weather and an open position in which it releases the opening,
- une charge déplaçable, en passant à travers l'ouverture du compartiment puis par- dessus de la tête d'un porteur du sac à dos :  a movable load, passing through the opening of the compartment and then over the head of a wearer of the backpack:
• d'une position rangée dans laquelle la charge se situe à l'intérieur du compartiment et le rabat est en position fermée, vers  • a stowed position in which the load is inside the compartment and the flap is in the closed position, towards
• une position déployée dans laquelle la charge se situe sur le torse du porteur du sac à dos,  • an extended position in which the load is on the torso of the rucksack carrier,
- des sangles reliant la charge au compartiment et aptes à retenir la charge sur le torse du porteur en position déployée. - Straps connecting the load to the compartment and able to hold the load on the torso of the wearer in the deployed position.
[003] Par exemple, un tel sac à dos est décrit dans la demande de brevet US 2009 014 490 dans le cas particulier où la charge est un tablier pare-balles également connu sous le terme de « tablier de protection balistique ».  [003] For example, such a backpack is described in US patent application 2009 014 490 in the particular case where the load is a bulletproof apron also known as the "ballistic protection apron".
[004] Ici, par tablier pare-balles, on désigne une paroi destinée à protéger la personne qui le porte contre des tires de balles ou autres munitions. Typiquement, ce tablier est l'une des faces d'un gilet pare-balles. [004] Here, by bulletproof apron, there is a wall intended to protect the person who wears it against bullets or other ammunition. Typically, this apron is one of the faces of a bulletproof vest.
[005] Ces tabliers sont généralement conformes à l'un des standards tels que ceux décrits dans la demande US 2009 014 490 à partir du paragraphe [0042].  [005] These aprons generally conform to one of the standards such as those described in application US 2009 014 490 from paragraph [0042].
[006] Dans les sacs à dos connus, pour pouvoir déplacer la charge de sa position rangée vers sa position déployée, il faut d'abord déplacer le rabat de sa position fermée vers sa position ouverte pour libérer l'ouverture. Ensuite, et seulement ensuite, la charge peut être déplacée de sa position rangée vers sa position déployée. Ainsi, lorsque la charge est enfermée à l'intérieur d'un compartiment refermé par le rabat, il faut au moins deux opérations distinctes (ouverture du rabat puis déplacement de la charge vers l'extérieur) avant de placer la charge dans sa position déployée. De plus, l'ouverture du rabat peut nécessiter la mise à terre du sac à dos. De ce fait, le temps de déplacement de la charge de sa position rangée à sa position déployée est long. In known knapsacks, to be able to move the load from its stowed position to its deployed position, it is first necessary to move the flap from its closed position to its open position to release the opening. Then, and only then, the load can be moved from its stowed position to its deployed position. Thus, when the load is enclosed inside a compartment closed by the flap, it takes at least two distinct operations (opening the flap and then moving the load outwards) before placing the load in its deployed position . In addition, opening the flap may require the grounding of the backpack. As a result, the travel time of the load from its stored position to its deployed position is long.
[007] Pour remédier à cet inconvénient, il a déjà été proposé de placer la charge dans un compartiment dépourvu de rabat. Par exemple, une telle solution est divulguée dans la demande de brevet US 6 419 132. Le déplacement de la charge vers sa position déployée est alors beaucoup plus rapide. Toutefois, l'absence de rabat pose différents problèmes. Par exemple, la pluie ou d'autres objets peuvent tomber dans ce compartiment puisque son ouverture n'est pas protégée par le rabat. De plus, l'absence de rabat rend le camouflage de la charge plus difficile. Ce dernier point est particulièrement important lorsque le sac à dos est utilisé pour des applications militaires. En effet, dans ce cas, la charge peut être un tablier pare-balles sur lequel sont fixées des armes ou des munitions. [007] To overcome this drawback, it has already been proposed to place the load in a compartment without a flap. For example, such a solution is disclosed in US patent application 6,419,132. Moving the load to its deployed position is then much faster. However, the absence of flap poses different problems. For example, rain or other objects can fall into this compartment because its opening is not protected by the flap. In addition, the absence of flap makes the camouflage of the load more difficult. This last point is particularly important when the backpack is used for military applications. Indeed, in this case, the load can be a bulletproof apron on which are fixed weapons or ammunition.
[008] L'invention vise à remédier à au moins l'un de ces inconvénients. Elle a donc pour objet un sac à dos dans lequel le sac à dos comprend aussi :  [008] The invention aims to remedy at least one of these disadvantages. It therefore relates to a backpack in which the backpack also includes:
- un passage entre le bord de l'ouverture du compartiment et le rabat en position fermée, et a passage between the edge of the opening of the compartment and the flap in the closed position, and
- au moins une poignée reliée à la charge, cette poignée faisant saillie à l'extérieur du sac à dos par l'intermédiaire de ce passage. at least one handle connected to the load, this handle protruding outside the backpack via this passage.
[009] Dans le sac à dos ci-dessus, la poignée permet dans un même mouvement d'ouvrir le rabat et d'extraire la charge du compartiment. Cela permet donc de passer très rapidement de la position rangée à la position déployée. En effet, la poignée est accessible depuis l'extérieur du sac. Il n'est donc pas nécessaire d'ouvrir le rabat avant de pouvoir tirer la charge. De plus, le déplacement de la charge sous l'effet de la traction appliquée sur la poignée permet d'ouvrir le rabat en même temps.  [009] In the backpack above, the handle allows in the same movement to open the flap and extract the load compartment. This allows to move very quickly from the stowed position to the deployed position. Indeed, the handle is accessible from the outside of the bag. It is therefore not necessary to open the flap before being able to pull the load. In addition, the displacement of the load under the effect of traction applied to the handle opens the flap at the same time.

[0014] Dans la suite de cette description, les caractéristiques et fonctions bien connues de l'homme du métier ne sont pas décrites en détail. De plus, dans cette description, les termes « haut » / « bas » / « supérieur » / « inférieur » sont définis par rapport à une direction Y d'un repère orthogonal XYZ. La direction Y est la direction verticale. Les directions X et Z sont des directions horizontales. L'avant et l'arrière sont définis par rapport à la direction Z.  In the following description, the features and functions well known to those skilled in the art are not described in detail. In addition, in this description, the terms "high" / "low" / "higher" / "lower" are defined with respect to a Y direction of an orthogonal XYZ coordinate system. The Y direction is the vertical direction. The X and Z directions are horizontal directions. The front and the back are defined with respect to the direction Z.
[0015] Les figures 1 et 2 représentent un sac à dos 2. Ce sac à dos 2 a une apparence extérieure similaire à celle de sacs à dos ordinaires telles qu'un sac à dos de randonneurs.  Figures 1 and 2 show a backpack 2. This backpack 2 has an external appearance similar to that of ordinary backpacks such as a backpack of hikers.
[0016] Le sac à dos 2 comporte un compartiment principal 4 fermé par un rabat 6. [0017] Le compartiment 4 est destiné à recevoir des charges. Il définit à cet effet un espace creux 8 suffisamment grand pour recevoir les charges en question. Par exemple, le volume du creux 8 est de préférence supérieur à 10, 20 ou 30 litres.  The backpack 2 has a main compartment 4 closed by a flap 6. The compartment 4 is intended to receive loads. It defines for this purpose a hollow space 8 large enough to receive the charges in question. For example, the volume of the hollow 8 is preferably greater than 10, 20 or 30 liters.
[0018] Ici, ce creux 8 a une forme sensiblement parallélépipédique. Pour cela, le compartiment 4 présente un fond horizontal 10, une face avant 12, une face arrière verticale 14 et deux faces latérales verticales 16. Sur la figure 2, seule une de ces faces latérales 16 est visible. Here, this hollow 8 has a substantially parallelepiped shape. For this, the compartment 4 has a horizontal bottom 10, a front face 12, a vertical rear face 14 and two vertical side faces 16. In Figure 2, only one of these side faces 16 is visible.
[0019] Par exemple, le compartiment 4 est réalisé en tissu.  For example, the compartment 4 is made of fabric.
[0020] Ce compartiment 4 comporte dans sa partie supérieure une ouverture 20 suffisamment grande pour introduire et retirer les charges de l'intérieur du compartiment 4. Ici, cette ouverture 20 est sensiblement rectangulaire. Par exemple, la largeur et la profondeur de cette ouverture 20 sont, de préférence, supérieures, respectivement, à 20 centimètres et 15 centimètres. [0021] La face avant 12 comporte une inscription 22 (seulement visible sur la figure 8) dans sa partie supérieure. La hauteur de cette inscription est typiquement supérieure à 3 cm et de préférence supérieure à 5 cm et sa largeur, dans une direction horizontale, est typiquement supérieure à 10 cm. This compartment 4 has in its upper part an opening 20 large enough to introduce and remove the charges from the inside of the compartment 4. Here, this opening 20 is substantially rectangular. For example, the width and depth of this opening 20 are preferably greater, respectively, to 20 centimeters and 15 centimeters. The front face 12 has an inscription 22 (only visible in Figure 8) in its upper part. The height of this inscription is typically greater than 3 cm and preferably greater than 5 cm and its width, in a horizontal direction, is typically greater than 10 cm.
[0022] Le rabat 6 est déplaçable entre une position fermée (représentée sur la figure 1 ) et une première position ouverte (représentée sur la figure 2). The flap 6 is movable between a closed position (shown in Figure 1) and a first open position (shown in Figure 2).
[0023] Dans sa position fermée, le rabat obstrue complètement l'ouverture 20 pour protéger le creux 8 des intempéries. Dans sa position ouverte, au contraire, le rabat 6 libère l'ouverture 20 ce qui permet l'introduction de charge à l'intérieur du compartiment 4. In its closed position, the flap completely obstructs the opening 20 to protect the hollow 8 from the weather. In its open position, on the contrary, the flap 6 releases the opening 20 which allows the introduction of charge inside the compartment 4.
[0024] Ici, le rabat 6 présente une face supérieure 30 sensiblement rectangulaire qui s'étend un peu au-delà du bord de l'ouverture 20.  Here, the flap 6 has a substantially rectangular upper face 30 which extends a little beyond the edge of the opening 20.
[0025] De plus, la face 30 est entourée sur sa périphérie par un rebord avant 32, un rebord arrière 34 et des rebords latéraux 36.  In addition, the face 30 is surrounded on its periphery by a front flange 32, a rear flange 34 and lateral flanges 36.
[0026] Le rebord avant 32 et les rebords latéraux 36 descendent le long, respectivement, de la face avant 12 et des faces latérales 16 dans la position fermée du rabat 6. Ce chevauchement des rebords 32 et 36 avec les faces 12 et 16 permet d'assurer une meilleure étanchéité dans la position fermée. The front flange 32 and the lateral flanges 36 descend along, respectively, the front face 12 and the side faces 16 in the closed position of the flap 6. This overlap of the flanges 32 and 36 with the faces 12 and 16 allows to ensure a better seal in the closed position.
[0027] De plus, ici, le rebord 32 est suffisamment long pour recouvrir la totalité de l'inscription 22 en position fermée. Par exemple, le rebord 32 fait plus de 20 cm de large sur plus de 10 cm de haut.  In addition, here, the rim 32 is long enough to cover the entire registration 22 in the closed position. For example, the rim 32 is more than 20 cm wide by more than 10 cm high.
[0028] Des fermetures 40, 41 sont prévues sur la face avant 12 pour verrouiller le rabat 6 dans sa position fermée. Dans leurs positions verrouillées, chacune de ces fermetures 40, 41 relie mécaniquement l'extrémité inférieure du rebord 32 à la face avant 12. Ces fermetures sont déplaçables d'une position verrouillée, représentée sur la figure 1 , vers une position déverrouillée, représentée sur la figure 2.  Closures 40, 41 are provided on the front face 12 to lock the flap 6 in its closed position. In their locked positions, each of these closures 40, 41 mechanically connects the lower end of the flange 32 to the front face 12. These closures are movable from a locked position, shown in Figure 1, to an unlocked position, shown in FIG. Figure 2.
[0029] Dans la position verrouillée, les fermetures 40 et 41 tendent le rebord 32 pour recouvrir l'inscription 22. In the locked position, the closures 40 and 41 tend the flange 32 to cover the inscription 22.
[0030] Dans la position déverrouillée, le rabat 6 peut basculer de sa position fermée vers une première position ouverte représentée sur la figure 2. Dans la position déverrouillée, chaque fermeture 40, 41 se dissocie en deux parties dont l'une reste solidaire de la face avant 12 et l'autre reste solidaire du rabat 6.  In the unlocked position, the flap 6 can swing from its closed position to a first open position shown in Figure 2. In the unlocked position, each closure 40, 41 dissociates into two parts, one of which remains attached to the front face 12 and the other remains secured to the flap 6.
[0031] Les fermetures 40, 41 sont déplaçables entre leurs positions verrouillées et déverrouillées de façon réversible.  The closures 40, 41 are movable between their locked positions and unlocked reversibly.
[0032] Deux bretelles 44, 45 sont fixées sur la face arrière 14 entre un point d'attache haut et un point d'attache bas. Ces bretelles 44, 45 permettent de transporter le sac à dos 2 sur le dos d'un être humain, appelé par la suite « porteur ».Two straps 44, 45 are fixed on the rear face 14 between a high attachment point and a low attachment point. These straps 44, 45 can carry the backpack 2 on the back of a human being, called "carrier".
Ces bretelles sont conçues pour qu'une partie du poids du sac à dos 2 repose sur les épaules du porteur. [0033] De plus, le sac à dos 2 comprend une ceinture en deux morceaux 48A et 48B destinés à se rejoindre pour ceinturer le torse du porteur. Cette ceinture permet de transférer l'autre partie du poids du sac à dos 2 vers le porteur. Chaque morceau 48A, 48B a une extrémité directement fixée dans la partie inférieure de la face arrière et une autre extrémité libre pourvue d'une partie mâle ou femelle d'une attache agrafable et, en alternance, dégrafable. These straps are designed so that a portion of the weight of the backpack 2 rests on the shoulders of the wearer. In addition, the backpack 2 comprises a belt in two pieces 48A and 48B intended to meet to surround the torso of the wearer. This belt transfers the other part of the weight of the backpack 2 to the wearer. Each piece 48A, 48B has one end directly fixed in the lower part of the rear face and another free end provided with a male or female part of a staple fastener and, alternatively, removable.
[0034] Le sac à dos 2 comprend une charge 50 déplaçable entre une position rangée représentée sur la figure 1 et une position déployée représentée sur la figure 6. La suite de cette description est faite dans le cas particulier où la charge 50 est un tablier pare-balles.  The backpack 2 comprises a load 50 movable between a stowed position shown in Figure 1 and an extended position shown in Figure 6. The following description is made in the particular case where the load 50 is an apron bulletproof.
[0035] Dans la position rangée, le tablier 50 est reçu à l'intérieur du compartiment 4 et le rabat 6 est dans sa position fermée. Dans sa position déployée, le tablier 50 recouvre la majorité du torse du porteur.  In the stowed position, the apron 50 is received inside the compartment 4 and the flap 6 is in its closed position. In its deployed position, the apron 50 covers the majority of the torso of the wearer.
[0036] Par exemple, ce tablier 50 est conforme à l'une des normes citées dans la demande de brevet US 2009 014 490.  For example, this apron 50 conforms to one of the standards cited in US patent application 2009 014 490.
[0037] Dans ce cas particulier, le tablier 50 s'étend essentiellement dans un plan vertical dans sa position rangée. Dans cette position, le tablier présente un bord supérieur 52 sensiblement horizontal et un bord inférieur 54 sensiblement horizontal. [0038] Le bord 54 comprend une encoche 56 pour le passage de la tête du porteur. [0039] Le bord 52 est mécaniquement relié à une poignée 58 qui fait saillie à l'extérieur du sac 2 lorsque le tablier 50 est dans sa position rangée.  In this particular case, the apron 50 extends essentially in a vertical plane in its stowed position. In this position, the apron has a substantially horizontal upper edge 52 and a substantially horizontal lower edge 54. The edge 54 comprises a notch 56 for the passage of the head of the wearer. The edge 52 is mechanically connected to a handle 58 which protrudes outside the bag 2 when the apron 50 is in its stowed position.
[0040] Des attaches 60, 62 sont prévues sur la face arrière 14 pour retenir le rabat 6 solidaire du compartiment 4 lorsque celui-ci se déplace de sa position rangée vers sa première position ouverte. Ces attaches 60, 62 remplissent la fonction de charnières lors de ce déplacement. Ces attaches 60, 62 remplissent d'autres fonctions et seront décrites plus loin. Fasteners 60, 62 are provided on the rear face 14 to retain the flap 6 secured to the compartment 4 when it moves from its stowed position to its first open position. These fasteners 60, 62 fulfill the function of hinges during this movement. These fasteners 60, 62 fulfill other functions and will be described later.
[0041] La figure 3 représente plus en détail la partie supérieure du tablier 50.  Figure 3 shows in more detail the upper part of the apron 50.
[0042] La poignée 58 est ici une anse dont chaque extrémité et fixée en un point d'attache respectif au bord 52.  The handle 58 is here a handle whose each end and fixed at a respective point of attachment to the edge 52.
[0043] Dans ce mode de réalisation, la poignée 58 comprend également une lanière transversale 64 disposée à mi-chemin entre le bord 52 et l'extrémité supérieure de la poignée 58. Cette lanière 64 permet de rigidifier la poignée 58. In this embodiment, the handle 58 also comprises a transverse strap 64 disposed midway between the edge 52 and the upper end of the handle 58. This strap 64 serves to stiffen the handle 58.
[0044] De part et d'autre de cette lanière 64 s'étendent deux cordons 66, 68. Une extrémité de chacun de ces cordons 66, 68 est reliée à la lanière 64.  On both sides of this strap 64 extend two cords 66, 68. One end of each of these cords 66, 68 is connected to the strap 64.
[0045] L'extrémité libre de ces cordons 66, 68 est destinée à être fixée respectivement, aux attaches 60, 62. A cet effet, ici, l'extrémité de chacun de ces cordons 66, 68 comporte une perle 69 enfilée sur le cordon et retenue à l'extrémité de ce cordon par un nœud 70. [0046] De préférence, les cordons 66 et 68 sont réalisés dans un matériau élastique dont le module de Young est inférieur à 5000 MPa et, de préférence, inférieure à 2000 MPa. The free end of these cords 66, 68 is intended to be fixed respectively to the fasteners 60, 62. For this purpose, here, the end of each of these cords 66, 68 comprises a bead 69 threaded on the cord and retained at the end of this cord by a knot 70. Preferably, the beads 66 and 68 are made of an elastic material whose Young's modulus is less than 5000 MPa and, preferably, less than 2000 MPa.
[0047] La fonction des cordons 66, 68 est décrite plus loin.  The function of the cords 66, 68 is described below.
[0048] La figure 4 montre, par transparence, la position du tablier 50 à l'intérieur du sac à dos 2 lorsque celui-ci est dans sa position rangée. A l'inverse, la figure 5 illustre, par transparence, l'intérieur du sac 2 lorsque le tablier 50 est dans sa position déployée. Figure 4 shows, by transparency, the position of the apron 50 inside the backpack 2 when it is in its stowed position. Conversely, Figure 5 illustrates, by transparency, the inside of the bag 2 when the apron 50 is in its deployed position.
[0049] Le bord 54 du tablier 50 est relié à la face arrière du compartiment 4 par l'intermédiaire de deux sangles 74, 76. Chacune de ces sangles 74, 76 est destinée à passer sur une épaule respective du porteur pour retenir, en position déployée, le tablier sur le torse du porteur. Une extrémité de chacune de ces sangles est donc fixée au tablier 50 tandis que l'autre extrémité est fixée à l'intérieur du compartiment 4 sur la face arrière 14.  The edge 54 of the apron 50 is connected to the rear face of the compartment 4 by means of two straps 74, 76. Each of these straps 74, 76 is intended to pass over a respective shoulder of the wearer to retain, in deployed position, the apron on the torso of the wearer. One end of each of these straps is thus fixed to the apron 50 while the other end is fixed inside the compartment 4 on the rear face 14.
[0050] De plus, ici, ces sangles 74, 76 comporte chacune au moins une boucle 78, 80 de réglage de la longueur de la sangle. Ces boucles 78, 80 permettent d'ajuster la position du tablier 50 lorsque celui-ci est en position déployée. In addition, here, these straps 74, 76 each comprises at least one loop 78, 80 for adjusting the length of the strap. These loops 78, 80 make it possible to adjust the position of the apron 50 when the latter is in the deployed position.
[0051] La figure 6 représente le tablier 50 dans sa position déployée sur un porteur 82. FIG. 6 shows the deck 50 in its deployed position on a carrier 82.
[0052] Comme illustré sur cette figure, le tablier 50 comporte de préférence plusieurs bandes 84 de fixation d'ustensiles. Seuls trois ustensiles 86 à 88 sont représentés sur la figure 6. Par exemple, l'ustensile 86 contient des munitions, l'ustensile 87 est une arme à feu et l'ustensile 88 est une poche porte-munition. As shown in this figure, the apron 50 preferably comprises several strips 84 for fixing utensils. Only three utensils 86 to 88 are shown in FIG. 6. For example, utensil 86 contains ammunition, utensil 87 is a firearm, and utensil 88 is a ammunition pouch.
[0053] Ces ustensiles sont fixés aux bandes 84 par l'intermédiaire de fixations amovibles conventionnelles.  These utensils are attached to the bands 84 via conventional removable fasteners.
[0054] La figure 7 représente plus en détail la partie supérieure de la face arrière 14 lorsque le tablier est dans sa position rangée. Dans cette position, la poignée 58 fait saillie à l'extérieur du sac par l'intermédiaire d'un passage. Ce passage est ici une fente ménagée entre le rebord arrière 34 du rabat 6 et le bord de l'ouverture 20. Cette fente 90 s'étend entre les deux attaches 60, 62.  Figure 7 shows in more detail the upper part of the rear face 14 when the deck is in its stowed position. In this position, the handle 58 protrudes outside the bag through a passage. This passage is here a slot formed between the rear edge 34 of the flap 6 and the edge of the opening 20. This slot 90 extends between the two fasteners 60, 62.
[0055] Grâce à cette fente 90, le porteur peut tirer sur le tablier 50 sans avoir à ouvrir au préalable le rabat 6. De plus, lorsque le porteur tire sur la poignée 50 pour extraire le tablier 50 du compartiment 4, une partie de cette force de traction est transmise aux attaches 60, 62 par l'intermédiaire des cordons 66 et 68 de manière à déplacer ces attaches de leurs positions agrafées (représentées sur la figure 7) vers une position dégrafée (représentée sur la figure 9).  With this slot 90, the wearer can pull the apron 50 without having to open before the flap 6. In addition, when the wearer pulls on the handle 50 to extract the apron 50 of the compartment 4, part of this pulling force is transmitted to the fasteners 60, 62 through the cords 66 and 68 so as to move these fasteners from their stapled positions (shown in Figure 7) to a degraded position (shown in Figure 9).
[0056] Dans la position dégrafée, les attaches 60, 62 ne relient plus mécaniquement le rebord arrière 34 à la face arrière 14 du compartiment 4. Ainsi, sous l'effet de la force de traction exercée sur la poignée 58, le tablier 50 pousse le rabat 6 qui pivote alors de sa position fermée vers une seconde position ouverte représentée sur la figure 8. Dans la seconde position ouverte, le rabat 6 se trouver sur l'avant du sac à dos. Pour pivoter de la position fermée à la seconde position ouverte, les fermetures 40 et 42 sont utilisées comme des charnières. Ces fermetures 40 et 42 permettent donc également de retenir le rabat 6 solidaire du compartiment 4 dans la seconde position ouverte. In the unclamped position, the fasteners 60, 62 no longer mechanically connect the rear flange 34 to the rear face 14 of the compartment 4. Thus, under the effect of the traction force exerted on the handle 58, the apron 50 push the flap 6 which then pivots from its closed position to a second open position shown on the figure 8. In the second open position, the flap 6 is on the front of the backpack. To pivot from the closed position to the second open position, the closures 40 and 42 are used as hinges. These closures 40 and 42 thus also allow to retain the flap 6 secured to the compartment 4 in the second open position.
[0057] Dans la position agrafée, ces attaches 60 et 62 retiennent le rabat 6 solidaire du compartiment 4 et remplissent également la fonction de charnières lorsque les fermetures 40 et 41 sont déverrouillées.  In the stapled position, these fasteners 60 and 62 retain the flap 6 secured to the compartment 4 and also perform the function of hinges when the closures 40 and 41 are unlocked.
[0058] Un mode particulier de réalisation de ces attaches 60 et 62 va maintenant être décrit en regard des figures 9 et 10.  A particular embodiment of these fasteners 60 and 62 will now be described with reference to Figures 9 and 10.
[0059] Chaque attache comprend une bande 100, par exemple réalisée en tissu, dont une extrémité est fixée au rebord arrière 34 du rabat 6. Par exemple, cette extrémité est cousue au rebord arrière 34. L'autre extrémité de la bande 100 est pourvue d'une boucle 102. Cette boucle 102 est réalisée à l'aide d'un cordon souple. De préférence, cette boucle 102 est réalisée dans un matériau élastique dont le module de Young est inférieur à 5000 MPa et, de préférence inférieur, à 2000 MPa. [0060] Chaque attache comprend également un bouton pression dont l'un de la partie maie et de la partie femelle est solidaire de la bande 100 et l'autre est solidaire de la face arrière 14 du sac à dos. Par exemple, sur les figures 9 et 10, la partie mâle 104 est solidaire de la face arrière 14 et la partie femelle 106 est solidaire de la bande 100.  Each fastener comprises a strip 100, for example made of fabric, one end of which is fixed to the rear flange 34 of the flap 6. For example, this end is sewn to the rear flange 34. The other end of the strip 100 is provided with a loop 102. This loop 102 is made using a flexible cord. Preferably, this loop 102 is made of an elastic material whose Young's modulus is less than 5000 MPa and, preferably less than 2000 MPa. Each fastener also comprises a snap button, one of the maie part and the female part is integral with the band 100 and the other is secured to the rear face 14 of the backpack. For example, in Figures 9 and 10, the male portion 104 is secured to the rear face 14 and the female portion 106 is secured to the band 100.
[0061] La boucle 102 est destinée à coopérer avec l'extrémité du cordon 66 ou 68 pour dégrafer le bouton pression en réponse à une traction sur la poignée 58.  The loop 102 is intended to cooperate with the end of the cord 66 or 68 to unclip the pressure button in response to traction on the handle 58.
[0062] La figure représente l'extrémité du cordon 66 mécaniquement raccordée à l'attache 60. A cet effet, la boucle 102 est enroulée autour du cordon 66. De plus, la boucle 102 est repliée de manière à ce qu'elle passe entre le bord arrière 34 du rabat 6 et le bouton pression. The figure shows the end of the cord 66 mechanically connected to the fastener 60. For this purpose, the loop 102 is wrapped around the cord 66. In addition, the loop 102 is folded so that it passes between the rear edge 34 of the flap 6 and the snap.
[0063] Dans ces conditions, tant que la traction exercée sur la poignée 58 est insuffisante pour dégrafer le bouton pression 104, 106, l'extrémité du cordon 66 reste solidaire de la bande 100. Quand au contraire, la force de traction exercée sur la poignée 58 est suffisamment forte, le bouton pression se désagrafe ce qui libère le rabat 6. De plus, lorsque le bouton pression est désagrafé, cela libère également l'extrémité de la boucle 102 qui se désenroule alors du cordon 66 et libère ainsi ce cordon. Ainsi, lorsque l'attache 60 est dans sa position désagrafée, le tablier 50 n'est plus reliée mécaniquement directement à cette attache. Il peut donc être librement tiré par-dessus la tête du porteur.  Under these conditions, as the traction exerted on the handle 58 is insufficient to unclip the pressure button 104, 106, the end of the cord 66 remains integral with the band 100. When on the contrary, the tensile force exerted on the handle 58 is strong enough, the pressure button is disengaged which releases the flap 6. Moreover, when the pressure button is unstaightened, it also frees the end of the loop 102 which then disengages from the cord 66 and thus releases cord. Thus, when the fastener 60 is in its unstaightened position, the apron 50 is no longer mechanically connected directly to this fastener. It can therefore be freely pulled over the wearer's head.
[0064] Les figures 12 à 14 illustrent l'utilisation du sac à dos 2.  Figures 12 to 14 illustrate the use of the backpack 2.
[0065] Initialement, le sac à dos 2 est porté par le porteur 82 à l'aide des sangles 44, Initially, the backpack 2 is carried by the carrier 82 with the aid of the straps 44,
45 et de la ceinture 48A, 48B. [0066] Egalement dans l'état initial, le tablier 50 est dans sa position rangée. Ainsi, seule la poignée 58 fait saillie à l'extérieur du sac à dos 2. Cette poignée 58 est alors située derrière la nuque du porteur 82. 45 and belt 48A, 48B. Also in the initial state, the apron 50 is in its stowed position. Thus, only the handle 58 protrudes outside the backpack 2. This handle 58 is then located behind the nape of the wearer 82.
[0067] Dans cet état, le sac à dos 2 présente l'apparence d'un sac à dos ordinaire. [0068] Lorsque le porteur 82 décide de se protéger, il attrape avec ses deux mains la poignée 58 et tire en direction de l'avant comme représenté par la flèche 1 10 sur la figure 13. En réponse à cette traction sur la poignée 58, les attaches 60, 62 basculent de leurs positions agrafées vers leurs positions dégrafées. Le rabat 6 est alors poussé par le tablier 50 de sa position fermée vers sa seconde position ouverte comme illustré sur la figure 13.  In this state, the backpack 2 has the appearance of a regular backpack. When the wearer 82 decides to protect himself, he catches with his two hands the handle 58 and pulls towards the front as shown by the arrow 1 10 in Figure 13. In response to this traction on the handle 58 , the fasteners 60, 62 swing from their stapled positions to their ungraded positions. The flap 6 is then pushed by the apron 50 from its closed position to its second open position as illustrated in FIG. 13.
[0069] Ensuite, le porteur 82 rabat le tablier 50 sur son torse comme indiqué par la flèche 1 12 de la figure 14. Le tablier 50 atteint alors sa position déployée. Dans cette position, il protège le porteur 82 contre des impacts de balle.  Then, the carrier 82 folds the apron 50 on his torso as indicated by the arrow 1 12 of Figure 14. The apron 50 then reaches its deployed position. In this position, it protects the wearer 82 against bullet impacts.
[0070] De plus, l'inscription 22 est dès lors visible. In addition, the inscription 22 is now visible.
[0071] De nombreux autres modes de réalisation sont possibles. Par exemple, la poignée peut prendre de nombreuses autres formes différentes. Ainsi, dans un mode de réalisation particulier, la poignée est formée d'une corde dont une extrémité est directement attachée au tablier 50 et dont l'autre extrémité est reliée à une prise rigide ayant sensiblement la forme d'un cylindre allongé. Many other embodiments are possible. For example, the handle can take many other different forms. Thus, in a particular embodiment, the handle is formed of a rope whose one end is directly attached to the deck 50 and whose other end is connected to a rigid plug having substantially the shape of an elongate cylinder.
[0072] Les cordons 66, 68 ne sont pas nécessairement directement raccordés à la poignée 58. Par exemple, ils peuvent aussi être raccordés au tablier 50. Ces cordons peuvent prendre différentes formes comme celles de rubans. The cords 66, 68 are not necessarily directly connected to the handle 58. For example, they can also be connected to the apron 50. These cords can take different forms such as ribbons.
[0073] Les bretelles 44, 45 et la ceinture peuvent être remplacées par tout autre dispositif remplissant les mêmes fonctions. Par exemple, ces bretelles et cette ceinture peuvent être remplacées par une veste dans le dos de laquelle est cousue le compartiment 4. Les bretelles 74, 76 peuvent également être remplacées par des arceaux rigides.  The straps 44, 45 and the belt can be replaced by any other device performing the same functions. For example, these straps and this belt can be replaced by a jacket in the back of which is sewn the compartment 4. The straps 74, 76 can also be replaced by rigid arches.
[0074] En variante, le sac à dos comporte une seule attache ou plus de deux attaches. Dans une autre variante, les attaches 60, 62 sont omises. Dans ce cas là, le rabat 6 est maintenu dans sa position fermée uniquement sous l'effet de son propre poids.  Alternatively, the backpack has a single fastener or more than two fasteners. In another variant, the fasteners 60, 62 are omitted. In this case, the flap 6 is held in its closed position only under the effect of its own weight.
[0075] De nombreux autres modes de réalisation des attaches 60 et 62 sont possibles. Par exemple, ces attaches peuvent aussi être réalisées à l'aide de bandes velcro® auto agrippantes plutôt que de boutons pressions.  Many other embodiments of the fasteners 60 and 62 are possible. For example, these fasteners can also be made using velcro® self-gripping strips rather than snaps.
[0076] Si nécessaire, une des deux fermetures 40, 41 est omise. Dans un autre mode de réalisation, ces deux ouvertures 40 et 41 sont omises. Dans ce cas, le rebord avant 32 du rabat 6 reste maintenu sur la face avant 12 essentiellement sous l'effet du poids du rabat. Il est également possible d'installer plus de deux fermetures entre le rabat 6 et le compartiment 4. [0077] En variante, les fermetures 41 et 42 sont remplacées par de simples lanières cousues d'un côté au rabat et de l'autre côté à la face avant 12. Dans ce mode de réalisation, ces fermetures ne sont pas déplaçables entre des positions verrouillée et déverrouillée. If necessary, one of the two closures 40, 41 is omitted. In another embodiment, these two openings 40 and 41 are omitted. In this case, the front edge 32 of the flap 6 remains maintained on the front face 12 essentially under the effect of the weight of the flap. It is also possible to install more than two closures between the flap 6 and the compartment 4. Alternatively, the closures 41 and 42 are replaced by simple strips sewn on one side to the flap and on the other side to the front face 12. In this embodiment, these closures are not movable between locked and unlocked positions.
[0078] Le sac à dos 2 peut contenir plusieurs compartiments. En particulier, le compartiment 4 peut contenir plusieurs poches secondaires situées à l'intérieur de ce compartiment principale. Dans ce cas, le tablier peut être contenu dans l'une de ces poches secondaires. The backpack 2 can contain several compartments. In particular, the compartment 4 may contain several secondary pockets located inside this main compartment. In this case, the apron can be contained in one of these secondary pockets.
[0079] De préférence, un autre tablier pare-balles est fixé sans aucun degré de liberté à la face arrière du sac à dos. Cet autre tablier permet donc de protéger le dos du porteur contre les impacts de balles.  Preferably, another bulletproof apron is attached without any degree of freedom to the rear face of the backpack. This other apron thus protects the back of the wearer against the impact of bullets.
[0080] Le sac à dos a été décrit ici dans le cas particulier où celui-ci est essentiellement réalisé en matériau souple tel que des tissus. Toutefois, en variante, il peut être réalisé dans d'autres matériaux tels que du cuir ou des polymères. Ces matériaux peuvent être rigides ou souples.  The backpack has been described here in the particular case where it is essentially made of flexible material such as fabrics. However, alternatively, it may be made of other materials such as leather or polymers. These materials can be rigid or flexible.
