Description

SAC A DOS A SUSPENSION SUSPENSION BACKPACK
La présente invention est relative à un sac à dos, notamment conçu pour les activités sportives telles que la randonnée pédestre, le sac permettant le stockage d'articles tels que des vêtements, ou encore tout type d'articles relatifs à la pratique de la randonnée.The present invention relates to a backpack, particularly designed for sports activities such as hiking, the bag for storing items such as clothing, or any type of articles relating to the practice of hiking .
L'invention sera notamment mise en œuvre par les fabricants d'articles textiles relatifs à la pratique d'activités sportives, notamment les fabricants de sacs. II est connu diverses conceptions de sacs qui comprennent communément une enveloppe pour la contenance des articles, et une paire de bretelles agencée dans le dos du sac pour permettre le support de l'enveloppe. Certaines de ces conceptions, parmi les plus élaborées, sont décrites au travers des documents WO 2004/082426, WO 2004/082427, US 2006/0151559, US 6.619.523, EP 1.618.813 et EP 1.602.299.The invention will be implemented in particular by manufacturers of textile articles relating to the practice of sports activities, in particular bag manufacturers. Various bag designs are known that commonly include an envelope for the capacity of the articles, and a pair of shoulder straps arranged in the back of the bag to support the envelope. Some of these designs, among the most elaborate, are described in the documents WO 2004/082426, WO 2004/082427, US 2006/0151559, US 6,619,523, EP 1,618,813 and EP 1.602.299.
Les documents WO 2004/082426 et US 6.619.523 divulguent notamment un sac à dos comprenant une structure solidaire d'une paire de bretelles et d'une ceinture de taille. L'enveloppe de sac proprement dit est montée coulissante et en suspension par rapport à cette structure. Cette conception permet en particulier d'amortir les chocs durant les déplacement de l'utilisateur portant le sac à dos chargé d'articles. Les moyens de suspension peuvent être disposés en partie inférieure de la structure pour déporter la charge vers la ceinture de taille. De tels sacs présentent pour inconvénient de déporter la charge dans le dos de l'utilisateur qui doit compenser ledit déport, par exemple en se courbant sensiblement vers l'avant pour rétablir une position convenable du centre de gravité durant la marche.WO 2004/082426 and US 6,619,523 disclose in particular a backpack comprising a structure integral with a pair of straps and a waist belt. The actual bag envelope is slidably mounted and suspended relative to this structure. This design allows in particular to cushion shocks during the movement of the user carrying the backpack loaded articles. The suspension means can be arranged in the lower part of the structure to move the load to the waist belt. Such bags have the disadvantage of deporting the load in the back of the user who must compensate said offset, for example by bending substantially forward to restore a suitable position of the center of gravity during walking.
Les documents WO 2004/082427, US 2006/0151559, EP 1.618.813 et EP 1.602.299 divulguent notamment un sac à dos comprenant des moyens de support flexibles, ou résilients, agencés entre le dos de l'enveloppe de sac proprement dit et la ceinture de taille, ces moyens permettant de déporter la charge du sac sur la ceinture et d'amortir les chocs durant les déplacements de l'utilisateur. Selon ces différentes conceptions, la ceinture de taille supporte l'enveloppe de sac, notamment au moyen de bras de support flexibles, ou résilients, agencés entre la ceinture et le dos de l'enveloppe ou une structure rapportée sur le dos de ladite enveloppe. Ces moyens permettent également de monter pivotante ou articulée, l'enveloppe de sac par rapport à la ceinture.The documents WO 2004/082427, US 2006/0151559, EP 1.618.813 and EP 1.602.299 disclose in particular a backpack comprising flexible or resilient support means arranged between the back of the actual bag envelope and the waist belt, these means for deporting the load of the bag on the belt and to dampen shocks during the movements of the user. According to these different designs, the waist belt supports the bag envelope, in particular by means of flexible support arms, or resilient, arranged between the belt and the back of the envelope or a structure attached to the back of said envelope. These means also allow to mount pivoting or articulated, the bag envelope relative to the belt.
Les sacs décrits dans les documents WO 2004/082427 et EP 1.618.813 comprennent des moyens de réglage de la position des bretelles par rapport au dos de l'enveloppe de sac, afin d'ajuster la position entre la paire de bretelles et la ceinture de taille. Des moyens de réglage sont également mis en œuvre dans le document US 2006/0151559, entre la ceinture de taille et le dos de l'enveloppe de sac, pour ajuster l'écartement entre la paire de bretelle et ladite ceinture. Selon ces trois documents, lorsque l'écartement entre la paire de bretelles et la ceinture est ajusté, ladite paire de bretelles est alors solidaire par rapport au dos de l'enveloppe du sac ; en cas d'un mauvais réglage, notamment lorsque l'écartement est trop faible, la paire de bretelles tend à supporter la charge qui est alors déportée en partie supérieure du sac sur les épaules de l'utilisateur, et non sur la ceinture de taille.The bags described in the documents WO 2004/082427 and EP 1.618.813 comprise means for adjusting the position of the straps relative to the back of the bag cover, in order to adjust the position between the pair of straps and the belt. of size. Adjustment means are also implemented in the document US 2006/0151559, between the waist belt and the back of the bag cover, to adjust the spacing between the pair of strap and said belt. According to these three documents, when the spacing between the pair of straps and the belt is adjusted, said pair of straps is then integral with the back of the bag envelope; in case of a bad adjustment, especially when the spacing is too small, the pair of shoulder straps tends to support the load which is then offset in the upper part of the bag on the shoulders of the user, and not on the waist belt .
Dans le document EP 1.602.299, la paire de bretelles est montée coulissante par rapport à une structure solidaire du dos du sac, ladite structure recevant lesdits moyens de support décrits ci-dessus et reliés à la ceinture de taille. Cette conception permet d'ajuster correctement la position de la paire de bretelles par rapport à la ceinture et d'assurer le déport de la charge sur la taille de l'utilisateur.In EP 1.602.299, the pair of straps is slidably mounted relative to a solidary structure of the back of the bag, said structure receiving said support means described above and connected to the waist belt. This design makes it possible to correctly adjust the position of the pair of shoulder straps relative to the belt and to ensure that the load is offset to the size of the user.
Par ailleurs, les conceptions de sac à dos selon les documents WO 2004/082427, US 2006/0151559, EP 1.618.813 et EP 1.602.299 présentent pour inconvénient de déporter la charge dans le dos de l'utilisateur. En effet, selon ces différentes conceptions de sacs, les bras de support sont flexibles, ou résilients, pour permettre un amortissement de la charge contenue dans l'enveloppe. Cela a pour inconvénient de déformer et courber lesdits bras de support de l'enveloppe, ce qui tend à déporter la charge vers l'extérieur, dans le dos de l'utilisateur. La charge pivote ou bascule alors vers l'arrière par rapport à la ceinture et tire sur la paire de bretelles, exerçant alors une pression sur les épaules de l'utilisateur qui est susceptible de ressentir une gêne au cours de ses déplacements. Inversement, une utilisation de bras de support trop rigide à pour inconvénient de réduire l'amortissement de l'enveloppe et donc d'augmenter les chocs.Furthermore, backpack designs according to WO 2004/082427, US 2006/0151559, EP 1.618.813 and EP 1.602.299 have the disadvantage of deporting the load in the back of the user. Indeed, according to these different designs of bags, the support arms are flexible, or resilient, to allow damping of the load contained in the envelope. This has the disadvantage of deforming and bending said support arm of the envelope, which tends to deport the load outwards, in the back of the user. The load then pivots or tilts backwards relative to the belt and pulls on the pair of straps, then exerting pressure on the shoulders of the user who is likely to feel discomfort during his movements. Conversely, a use of support arm too rigid to disadvantage of reducing the damping of the envelope and thus increase shocks.
En outre, selon ces différentes conceptions, les moyens de support flexibles présentent un encombrement important, notamment la section des bras support qui doivent disposer d'une résistance suffisante pour supporter la charge tout en limitant leur déformation. Cet encombrement présente pour inconvénient de décaler vers l'arrière la charge dans le dos de l'utilisateur qui doit alors s'incliner vers l'avant pour compenser ladite charge.In addition, according to these different designs, the flexible support means have a large size, including the section of the support arms which must have sufficient strength to support the load while limiting their deformation. This size has the disadvantage of shifting back the load in the back of the user who must then bow forward to compensate said load.
La présente invention a pour objet de pallier les inconvénients des sacs à dos existants, notamment décrits dans les documents antérieurs ci-dessus, en mettant en œuvre une nouvelle conception de sac à dos permettant de déporter la charge de l'enveloppe de sac au niveau de la ceinture de taille. Le sac selon l'invention présente pour avantage d'atténuer le déport la charge dans le dos de l'utilisateur, et de supprimer le pivotement de ladite charge au niveau de la ceinture de taille, ce qui permet d'atténuer la traction vers l'arrière exercée sur les bretelles, et donc réduit la pression sur les épaules. Cette conception a également pour avantage d'améliorer l'amortissement de la charge au niveau de la ceinture de taille, par rapport aux sacs à dos décrits dans les documents WO 2004/082427, US 2006/0151559, EP 1.618.813 et EP 1.602.299, en utilisant des moyens d'amortissant présentant de meilleures propriétés élastiques, tout en conservant convenablement plaquée la charge de l'enveloppe sur le dos de l'utilisateur.The present invention aims to overcome the disadvantages of existing backpacks, in particular described in the above documents, by implementing a new backpack design to deport the load of the bag envelope at the level of waist belt. The bag according to the invention has the advantage of attenuating the load offset in the back of the user, and to eliminate the pivoting of said load at the level of the waist belt, which helps to reduce the pull towards the waist. rear exerted on the shoulder straps, and therefore reduces the pressure on the shoulders. This design also has the advantage of improving the damping of the load at waist level, compared to backpacks described in WO 2004/082427, US 2006/0151559, EP 1.618.813 and EP 1.602 .299, by using damping means having better elastic properties, while appropriately keeping the load of the envelope on the back of the user.
Un autre objet de la présente invention est de concevoir un sac à dos qui présente des moyens de support d'épaisseur réduite afin de limiter l'espacement entre le dos de l'utilisateur et le dos du sac, ce qui atténue le décalage de la charge dans le dos de l'utilisateur.

L'armature du sac à dos comprend deux lames rigides latérales. Ces lames rigides sont agencées verticalement au moins en partie supérieure de la face arrière de l'enveloppe. Les deux bretelles sont montées coulissant sur ces deux lames. Par ailleurs, l'armature comprend également une lame rigide agencée horizontalement en partie inférieure de la face arrière de l'enveloppe de sac. De manière préférentielle, les deux lames rigides verticales et la lame rigide horizontale sont intégrées à la face arrière de l'enveloppe, ce qui présente pour avantage d'améliorer le placage de l'enveloppe sur le dos de l'utilisateur.The backpack comprises connecting means arranged between the belt assembly and the pair of shoulder straps, all constituting a set forming a holding member arranged to allow the vertically sliding assembly of the belt assembly relative to said back plane. . In addition, support means or suspension supports are arranged at least between the lower part of the belt assembly and the lower part of the dorsal plane to retain the load of the envelope under the belt, while maintaining the back plane on the back and damping the relative movements of the envelope relative to the back support member. The frame of the backpack includes two rigid side blades. These rigid blades are arranged vertically at least in the upper part of the rear face of the envelope. The two straps are slidably mounted on these two blades. Furthermore, the frame also comprises a rigid blade arranged horizontally in the lower part of the rear face of the bag envelope. Preferably, the two vertical rigid blades and the horizontal rigid blade are integrated into the rear face of the envelope, which has the advantage of improving the plating of the envelope on the back of the user.
De manière préférentielle, l'armature comprend également une structure en croix agencée pour exercer une pression sur la face arrière de l'enveloppe et maintenir ladite face arrière légèrement espacée du dos de l'utilisateur. Selon un mode de réalisation, cette structure en croix peut être disposée du côté externe de l'enveloppe, sur la face arrière de celle-ci, et solidaire des deux lames rigides verticales voire également de la lame rigide horizontale. Selon une variante de conception, cette structure en croix est indépendante des lames rigides verticales et/ou horizontales, et elle est solidarisée sur la face arrière de l'enveloppe, du côté interne de celle-ci. L'ensemble de ceinture comprend une ceinture de taille proprement dite constituant la partie inférieure. Cet ensemble de ceinture comprend éventuellement une pièce complémentaire rigide assujettie à ladite ceinture de taille, de préférence au moyen d'un montage à pivotement.

Les moyens de support à suspension comprennent des moyens élastiques, constitués notamment par au moins une bande élastique ou un ressort, ces moyens élastiques étant répartis uniformément par rapport à l'ensemble de ceinture, par exemple la ceinture. Selon un mode de réalisation de ces moyens de support à suspension, l'extrémité supérieure de la bande élastique ou du ressort est fixée à la ceinture, notamment au niveau de sa face interne. L'extrémité inférieure de la bande élastique ou du ressort est fixée au plan dorsal. En outre, l'extrémité inférieure de la bande élastique ou du ressort est fixée à la lame rigide horizontale. Selon une variante de réalisation de ces moyens de support à suspension, ceux-ci comprennent des moyens élastiques constitués notamment d'au moins une bande élastique, répartie uniformément par rapport à l'ensemble de ceinture. L'une des extrémités de ces moyens élastiques est fixée à l'élément de maintien dorsal, notamment à mi-hauteur de celui-ci, par exemple sur la partie supérieure de l'ensemble de ceinture, sur la partie inférieure de la paire de bretelles voire sur les moyens de liaison entre ledit ensemble de ceinture et ladite paire de bretelles. L'autre extrémité desdits moyens élastiques, notamment l'extrémité inférieure de la bande élastique, est fixée au plan dorsal, de préférence en partie haute de celui-ci. En outre, ces moyens élastiques, et notamment la bande élastique, s'étendent vers le bas et passent autour d'un élément de renvoi situé dans la partie inférieure dudit plan dorsal de manière à retenir la charge de l'enveloppe en-dessous de la ceinture et à favoriser le placage du plan dorsal sur l'élément de maintien dorsal. Les moyens de liaison agencés entre l'ensemble de ceinture et la paire de bretelles peuvent être conçus de différentes manières. Selon un mode de réalisation, ces moyens de liaison sont constitués d'une bande rigide ou une sangle souple dont l'extrémité supérieure est reliée à la paire de bretelles et l'extrémité inférieure est reliée à la ceinture. Selon une variante de conception, ces moyens de liaison comprennent des moyens d'ajustement agencés pour régler la longueur séparant l'ensemble de ceinture et la paire de bretelles. De manière préférentielle, ces moyens de liaison sont constitués d'une sangle souple reliée d'un côté à la paire de bretelles et de l'autre côté à l'ensemble de ceinture. De préférence, l'extrémité inférieure de cette sangle souple est fixée à l'ensemble ceinture et son extrémité supérieure est fixée au plan dorsal, la paire de bretelles comprenant en outre des moyens d'assemblage avec ladite sangle souple, ces moyens d'assemblage étant agencés pour verrouiller en position la paire de bretelles en tous points de ladite sangle souple. Ces moyens d'assemblage seront notamment constitués par une boucle de réglage du type boucle à came, au travers de laquelle passe la sangle souple. La description ci-après décrit différents modes de réalisation préférentiels du sac à dos selon l'invention. Cette description s'appuie sur des figures, parmi lesquelles :The suspension support means comprise elastic means, constituted in particular by at least one elastic band or a spring, these resilient means being uniformly distributed with respect to the belt assembly, for example the belt. According to one embodiment of these suspension support means, the upper end of the elastic band or the spring is attached to the belt, in particular at its inner face. The lower end of the elastic band or the spring is attached to the back plane. In addition, the lower end of the elastic band or the spring is attached to the horizontal rigid blade. According to an alternative embodiment of these suspension support means, these comprise elastic means consisting in particular of at least one elastic band, distributed uniformly with respect to the belt assembly. One of the ends of these elastic means is fixed to the back support element, in particular at mid-height thereof, for example on the upper part of the belt assembly, on the lower part of the pair of straps or on the connecting means between said belt assembly and said pair of straps. The other end of said elastic means, in particular the lower end of the elastic band, is fixed to the dorsal plane, preferably in the upper part thereof. In addition, these elastic means, and in particular the elastic band, extend downwards and pass around a deflection element located in the lower part of said dorsal plane so as to retain the load of the envelope below. belt and promote the plating of the back plane on the back support element. The connecting means arranged between the belt assembly and the pair of shoulder straps can be designed in different ways. According to a mode of realization, these connecting means are constituted by a rigid band or a flexible strap whose upper end is connected to the pair of straps and the lower end is connected to the belt. According to a variant of design, these connecting means comprise adjustment means arranged to adjust the length separating the belt assembly and the pair of straps.

These assembly means will be constituted in particular by a loop-type adjustment loop, through which the flexible strap passes. The following description describes various preferred embodiments of the backpack according to the invention. This description is based on figures, among which:
- la figure 1 représente un sac selon l'invention en vue de côté,FIG. 1 represents a bag according to the invention in side view,
- la figure 2 met en évidence un premier mode de réalisation du sac selon l'invention en vue de derrière,FIG. 2 shows a first embodiment of the bag according to the invention in view from behind,
- la figure 3 met en évidence un second mode de réalisation du sac selon l'invention en vue de derrière,FIG. 3 shows a second embodiment of the bag according to the invention in view from behind,
- la figure 4 met en évidence un troisième mode de réalisation du sac de l'invention, en vue de côté. Tel qu'illustré sur la figure 1, le sac à dos 1 selon l'invention comporte une enveloppe 2 de sac proprement dit. La face arrière 7 de l'enveloppe est équipée d'une armature, l'ensemble constitué par la face arrière et l'armature forme un plan dorsal 9. Ce plan dorsal est adjacent au dos de l'utilisateur lorsque ce dernier porte le sac. De manière préférentielle et non limitative, tel qu'illustré sur les figures 1 à 3, l'armature comprend deux lames rigides latérales 3a, 3b. Ces lames 3a, 3b sont agencées verticalement au moins en partie supérieure de la face arrière 7 de l'enveloppe 2, et de préférence sur toute sa hauteur. Ces lames verticales 3a, 3b reçoivent une paire de bretelles lia, llb, le montage entre lesdits éléments étant réalisé coulissant ou en glissière. Par ailleurs, l'armature comprend également une lame rigide 5 agencée horizontalement en partie inférieure de la face arrière 7 de l'enveloppe 2.- Figure 4 highlights a third embodiment of the bag of the invention, in side view. As illustrated in Figure 1, the backpack 1 according to the invention comprises a shell 2 of the bag itself. The rear face 7 of the envelope is equipped with an armature, the assembly formed by the rear face and the armature forms a dorsal plane 9. This back plane is adjacent to the back of the user when the latter carries the bag . In a preferential and nonlimiting manner, as illustrated in FIGS. 1 to 3, the armature comprises two lateral rigid blades 3a, 3b. These blades 3a, 3b are arranged vertically at least in the upper part of the rear face 7 of the casing 2, and preferably over its entire height. These vertical blades 3a, 3b receive a pair of straps 11a, 11b, the assembly between said elements being made slidably or slidably. Furthermore, the armature also comprises a rigid blade 5 arranged horizontally in the lower part of the rear face 7 of the casing 2.
De manière préférentielle, ces lames rigides verticales 3a, 3b et la lame rigide horizontale 5 sont constituées par une seule et même structure rigide en forme de U, telle qu'illustrée sur les figures 2 et 3, cette structure en U étant de préférence intégrée à la face arrière 7 de l'enveloppe 2.Preferably, these rigid vertical blades 3a, 3b and the horizontal rigid blade 5 are constituted by a single and U-shaped rigid structure, as illustrated in Figures 2 and 3, this U-shaped structure being preferably integrated at the rear face 7 of the envelope 2.
Selon une variante de réalisation, l'armature comprend une structure en croix agencée pour apporter de la rigidité au plan dorsal 9. Cette structure en croix est de préférence solidaire des extrémités supérieures et inférieures des armatures verticales. D'autres modes de mise en œuvre sont toutefois envisageables, comme par exemple l'agencement de cette structure en croix à l'intérieur de l'enveloppe 2, sur la face arrière 7 de celle-ci. Dans ce cas, la structure en croix est indépendante des armatures verticales. Cette structure en croix a pour fonction d'une part, d'exercer une pression sur la face arrière 7 de l'enveloppe 2 et ainsi d'empêcher que la charge contenue dans l'enveloppe 2 ne déforme la face arrière 7 et ne vienne au contact avec le dos de l'utilisateur et, d'autre part, de maintenir un léger espacement entre le dos de l'utilisateur et la face arrière 7 de l'enveloppe de sac pour assurer une ventilation.According to an alternative embodiment, the frame comprises a cross structure arranged to provide rigidity to the dorsal plane 9. This cross structure is preferably secured to the upper and lower ends of the vertical frames. Other embodiments are possible, however, such as the arrangement of this cross structure inside the casing 2, on the rear face 7 thereof. In this case, the cross structure is independent of the vertical frames. This cross structure has the function on the one hand, to exert pressure on the rear face 7 of the casing 2 and thus to prevent the load contained in the casing 2 deforms the rear face 7 and does not come in contact with the back of the user and, secondly, to maintain a slight spacing between the back of the user and the rear face 7 of the bag envelope to provide ventilation.
Selon une conception préférentielle, les lames rigides verticales 3a, 3b et la lame rigide horizontale 5 sont encastrées dans la face arrière 7 de l'enveloppe 2.According to a preferred design, the vertical rigid blades 3a, 3b and the horizontal rigid blade 5 are embedded in the rear face 7 of the casing 2.
Le sac 1 comprend un ensemble de ceinture de taille 13. Cet ensemble de ceinture de taille présente au moins une partie inférieure 15 qui est maintenue fermement autour de la taille d'un utilisateur, par exemple au moyen d'une boucle de ceinture ou d'un système de fermeture mâle et femelle, à endiquetage.The bag 1 comprises a size waistband assembly 13. This waistband assembly has at least one lower portion 15 which is held firmly around the waist of a wearer, for example by means of a belt buckle or waistband. 'a male and female closure system, with a bite.
Le sac comprend des moyens de liaison 17, 19. Ces moyens sont agencés entre l'ensemble de ceinture 13 et la paire de bretelles lia, 11b. L'ensemble est solidaire et constitue un élément de maintien dorsal 21 durant son utilisation. Cet assemblage permet le montage coulissant de l'ensemble de ceinture 13 par rapport aux lames verticales 3a, 3b, et donc par rapport au plan dorsal 9.The bag comprises connecting means 17, 19. These means are arranged between the belt assembly 13 and the pair of shoulder straps 11a, 11b. The assembly is integral and constitutes a back support element 21 during use. This assembly allows the sliding assembly of the belt assembly 13 with respect to the vertical blades 3a, 3b, and thus with respect to the dorsal plane 9.
Tel qu'illustré sur les figures 1 à 4, des moyens de support à suspension sont agencés au moins entre la partie inférieure 15 de l'ensemble de ceinture 13 et la partie inférieure 25 du plan dorsal 9. Ces moyens ont pour fonction de retenir la charge de l'enveloppe 2 en maintenant plaqué le plan dorsal 9 sur le dos et en amortissant les mouvements relatifs de l'enveloppe 2 par rapport à l'élément de maintien dorsal 21.As shown in FIGS. 1 to 4, suspension support means are arranged at least between the lower portion 15 of the belt assembly 13 and the lower portion 25 of the dorsal plane 9. These means serve to retain the load of the casing 2 while keeping the back plane 9 pressed against the back and damping the relative movements of the casing 2 with respect to the backing element 21.
Tel qu'illustré sur les figures 2 et 3, la partie inférieure de l'ensemble de ceinture 13 comprend une ceinture de taille 15 proprement dite. Les moyens de support à suspension comprennent des moyens élastiques qui s'étendent en dessous de la ceinture 15. De manière préférentielle et non limitative, ces moyens élastiques sont constitués par au moins une bande élastique 23. On peut toutefois envisager l'utilisation de tout autres moyens élastiques, comme par exemple des ressorts. Ces moyens élastiques sont répartis uniformément par rapport à la ceinture 15, et seront par exemple fixés au niveau de la face interne 27 de ladite ceinture 15.As illustrated in Figures 2 and 3, the lower portion of the waistband assembly 13 includes a waistband 15 itself. The suspension support means comprise resilient means which extend below the belt 15. Preferably, and not limited to, these elastic means consist of at least one elastic band 23. However, it is possible to envisage the use of any other elastic means, such as springs. These elastic means are distributed uniformly with respect to the belt 15, and will for example be fixed at the inner face 27 of said belt 15.
Selon ces deux modes de réalisation représentés aux figures 2 et 3, l'extrémité supérieure 29 de la bande élastique 23 est fixée à la face interne 27 de la ceinture 15, tandis que son extrémité inférieure 31 est fixée au plan dorsal 9, notamment à sa partie inférieure constituée par la lame rigide horizontale 5.According to these two embodiments shown in Figures 2 and 3, the upper end 29 of the elastic band 23 is fixed to the inner face 27 of the belt 15, while its lower end 31 is fixed to the dorsal plane 9, particularly to its lower part constituted by the horizontal rigid blade 5.
La position de la bande élastique 23 sous la ceinture de taille 15 permet donc de retenir l'enveloppe de sac, en évitant que celle-ci ne pivote vers l'arrière par rapport à l'ensemble de ceinture 13 et la paire de bretelles lia, 11b constituant en partie l'élément de maintien dorsal 21, quel que soit le module d'élasticité choisi pour ladite bande élastique. De plus, le montage en liaison glissière dudit élément de maintien dorsal 21 par rapport au plan dorsal 9, notamment au niveau des bretelles lia, 11b, et éventuellement au niveau de l'élément de ceinture 13 permet de maintenir plaqués convenablement les deux éléments 9, 21.The position of the elastic band 23 under the waist belt 15 thus allows the bag cover to be retained, preventing it from pivoting backwards relative to the belt assembly 13 and the pair of shoulder straps 11a. 11b partially constituting the backing element 21, regardless of the modulus of elasticity chosen for said elastic band. In addition, the slide connection assembly of said back support member 21 with respect to the back plane 9, in particular at the shoulder straps 11a, 11b, and possibly at the level of the belt element 13 makes it possible to keep the two elements 9, 21 properly fastened.
Selon le premier mode de réalisation illustré en figure 2, l'ensemble de ceinture 13 est constitué uniquement par la ceinture de taille 15 telle que décrite ci-dessus. Les moyens de liaison, agencés entre la ceinture de taille 15 et la paire de bretelles lia, 11b, sont constitués d'une bande rigide 17. L'extrémité supérieure 33 de la bande rigide 17 est reliée à la partie centrale de la paire de bretelles lia, llb. Par ailleurs, l'extrémité inférieure 35 de la bande rigide 17 est reliée à la partie supérieure de la ceinture 15. Le tout forme un ensemble monobloc. Cette bande rigide peut toutefois être remplacée par une sangle souple.According to the first embodiment illustrated in FIG. 2, the belt assembly 13 consists solely of the waist belt 15 as described above. The connecting means, arranged between the waist belt 15 and the pair of straps 11a, 11b, consist of a rigid band 17. The upper end 33 of the rigid strip 17 is connected to the central portion of the pair of straps. braces lia, llb. Moreover, the lower end 35 of the rigid band 17 is connected to the upper part of the belt 15. The whole forms a one-piece assembly. This rigid band can however be replaced by a flexible strap.
Selon ce premier mode de conception illustré en figure 2, les moyens de support à suspension du sac 1 comprennent deux bandes élastiques 37a, 37b supplémentaires réparties de chaque côté de la bande rigide 17. L'extrémité supérieure 39a, 39b des deux bandes élastiques 37a, 37b est reliée à la paire de bretelles lia, llb, notamment au niveau de sa partie centrale. Leur extrémité inférieure 41a, 41b est quant à elle reliée au plan dorsal 9, notamment au niveau des lames rigides verticales 3a, 3b, tel qu'illustré sur la figure 2.According to this first embodiment illustrated in FIG. 2, the suspension support means of the bag 1 comprise two additional elastic strips 37a, 37b distributed on each side of the rigid strip 17. The upper end 39a, 39b of the two elastic bands 37a 37b is connected to the pair of straps 11a, 11b, in particular at its central portion. Their lower end 41a, 41b is connected to the dorsal plane 9, in particular at the vertical rigid blades 3a, 3b, as shown in FIG. 2.
Selon le second mode de conception illustré en figue 3, l'ensemble de ceinture 13 du sac 1 est constitué par la ceinture de taille 15 et par une pièce rigide 43. Cette pièce 43 comprend une extrémité inférieure 45 et deux extrémités latérales 47a, 47b. L'extrémité inférieure 45 est montée à pivotement par rapport à la ceinture 15 et les extrémités latérales supérieures 47a, 47b sont montées en liaison glissière par rapport aux lames rigides verticales 3a, 3b.According to the second embodiment illustrated in FIG. 3, the belt assembly 13 of the bag 1 is constituted by the waist belt 15 and by a rigid piece 43. This piece 43 comprises a lower end 45 and two lateral ends 47a, 47b . The lower end 45 is pivotally mounted relative to the belt 15 and the upper lateral ends 47a, 47b are mounted in sliding connection relative to the vertical rigid blades 3a, 3b.
Selon ce second mode, les moyens de liaison sont constitués par des moyens d'ajustement 19 agencés entre la pièce rigide 43 et la paire de bretelles lia, llb. Ces moyens d'ajustement 19 permettent le réglage de la longueur séparant la pièce rigide 43 et la paire de bretelles lia, llb, pour ajuster au mieux la position des bretelles par rapport à la ceinture de taille 15.According to this second embodiment, the connecting means are constituted by adjustment means 19 arranged between the rigid piece 43 and the pair of straps 11a, 11b. These adjustment means 19 allow the adjustment of the length separating the rigid piece 43 and the pair of straps 11a, 11b, to adjust to the better the position of the straps relative to the waist belt 15.
De manière préférentielle et non limitative, les moyens d'ajustement sont constitués d'une sangle 19 munie de moyens de réglage en longueur.Preferably and without limitation, the adjustment means consist of a strap 19 provided with length adjustment means.
L'extrémité supérieure 49 de la sangle 19 est reliée à la partie centrale de la paire de bretelles lia, llb. Son extrémité inférieure 51 est reliée à la partie centrale supérieure de la pièce rigide 43.The upper end 49 of the strap 19 is connected to the central portion of the pair of shoulder straps 11a, 11b. Its lower end 51 is connected to the upper central part of the rigid part 43.
De tels moyens d'ajustement peuvent également être mis en œuvre sur le premier mode de conception illustré en figure 2 lorsque les moyens de liaison sont constitués d'une sangle en remplacement de la bande rigide 17. Dans ce cas, et selon un mode préférentiel de conception, la sangle est fixée à son extrémité inférieure à la ceinture de taille 15, tandis que son extrémité supérieure est fixée au plan dorsal 9. En outre, la paire de bretelles lia, llb comprend dans sa partie centrale des moyens d'assemblage du type boucle de réglage à came dans laquelle passe la sangle reliée à ces extrémités inférieure et supérieure respectivement à la ceinture 15 et au plan dorsal. Ainsi, la boucle de réglage permet de verrouiller la paire de bretelles lia, llb en tous points sur la sangle, entre ces deux extrémités. De tels moyens de réglage peuvent également être prévus sur le second mode de conception illustré en figure 3 voire sur tout autre mode de conception du sac selon l'invention. Selon le mode de conception de la figure 3, la pièce rigide 43 est notamment de forme triangulaire. La base 53 du triangle est disposée en partie supérieure sur laquelle est fixée la sangle de réglage 19. Les deux extrémités latérales supérieures 47a, 47b sont constituées par les deux extrémités de la base. Le sommet 55 du triangle est disposé en partie inférieure et constitue ladite extrémité inférieure 45.Such adjustment means can also be implemented on the first design mode illustrated in FIG. 2 when the connecting means consist of a strap replacing the rigid band 17. In this case, and according to a preferential mode of design, the strap is attached at its lower end to the waist belt 15, while its upper end is fixed to the dorsal plane 9. In addition, the pair of shoulder straps 11a, 11b comprises in its central part assembly means the type of cam adjustment loop in which the strap connected to these lower and upper ends respectively to the belt 15 and to the dorsal plane. Thus, the adjustment loop makes it possible to lock the pair of straps 11a, 11b at all points on the strap, between these two ends. Such adjustment means may also be provided on the second design mode illustrated in Figure 3 or on any other design mode of the bag according to the invention. According to the embodiment of FIG. 3, the rigid piece 43 is in particular of triangular shape. The base 53 of the triangle is arranged in the upper part on which is fixed the adjustment strap 19. The two upper lateral ends 47a, 47b are constituted by the two ends of the base. The top 55 of the triangle is arranged in the lower part and constitutes said lower end 45.
