    [0001] BACKGROUND The present invention relates to a backpack, particularly a backpack for a sporting practice such as hiking or running, especially in the mountains. This backpack is intended especially for sportsmen, such as hikers, runners, mountaineers or fans of orientation races or climbing. Many forms of backpacks have been developed to carry loads on the back of a user. These bags are used for example in walking, traveling, hiking, climbing, mountaineering or cycling. In a conventional manner, a backpack has a main pocket comprising panels of flexible material, contiguous to a back portion of rigid or semi-rigid material or incorporating a reinforcement providing rigidity. This rigidity ensures a good performance of the backpack, especially when it is not worn. The main pocket is designed to receive a load and is held by two carrying straps attached to the back portion. US-A-2010/0237110 discloses a backpack comprising a back panel with shoulder straps. The back panel is provided to support various storage pockets of different volume, these pockets being removable. A frame with two "T" bars provides a continuous connection between the pocket and the back panel, which prevents air circulation between the pocket and the straps, and does not promote the evacuation of perspiration. In addition, the "T" bars are rigid and penalize the comfort of the user.
    [0002] The construction is not intended to allow relative movement between the pocket and the back panel once the backpack is assembled. US-A-2010/0308086 discloses a backpack with a pocket whose back panel, interfacing with the back, is flexible. The straps are directly attached to the back panel of the pocket. The pocket is not movable relative to the back when the backpack is worn.
    [0003] All these bags have a certain rigidity when worn which causes discomfort, on the one hand, to not conform well to the morphology of the back, and on the other hand, during rotations of the bust, bringing a resistance to movement. The invention aims to solve one or more of the above disadvantages. An object of the invention is to provide an improved backpack bringing a comfort of 30 portage. Another aim is notably to improve the freedom of movement of the user wearing such a backpack. Another goal is to improve the interface with the back so that it is the most adapted to the morphology of the back of the user when it moves. Another object is to have a movable pocket whose positioning adjusts when the user is in motion. Another goal is to improve back ventilation. The invention proposes a backpack comprising: - a frame comprising two straps and at least one connecting element connecting transversely the straps at the back, a rear portion of each strap and the connection element forming a back portion of the frame having a flexibility allowing a deformation of the dorsal part in order to adapt to the morphology of the user's back, statically or in movement, - a pocket delimiting a volume for receiving a load, the pocket comprising a back wall having a flexibility allowing the deformation of the dorsal wall to adapt to the morphology of the user's back, statically or in movement, the dorsal wall having an overlap zone with the dorsal portion of the frame, the dorsal wall being connected to the frame by connecting means allowing relative movement between the back wall and the frame, at least vertically and / or horizontally, in the overlap zone, the connecting means being located outside the recovery zone. Thanks to the invention, the pocket is movable relative to the frame, which allows good freedom of movement for the user. In addition, the flexibility of the back of the backpack allows the backpack to follow the movements of the user, which improves comfort. According to advantageous but non-mandatory aspects of the invention, such a backpack can incorporate one or more of the following features, taken in any technically permissible combination: At least one side edge of the back wall is discontinuously connected to the frame and in that at least one free passage between the lateral edge and the frame is not provided with connecting means, the free passage having a height greater than or equal to 15% of the total height of the dorsal wall. - The back wall is connected to the frame only at the edges of the back wall. - The backpack comprises an upper compression system for moving an upper portion of a rear wall of the pocket towards the back wall. the upper compression system comprises, on each side of the backpack, an upper clamping mechanism, each upper clamping mechanism comprising: a link, two anchoring points of the link with the rear wall, the distance between the anchoring points being greater than 10 centimeters, along a lateral edge of the wall, - an upper adjustment means in which at least one strand of the link passes, the upper adjustment means being arranged on a shoulder strap, at the level of the shoulder of the user or on a front portion of the shoulder strap, the upper adjusting means for adjusting at least the length of a strand extending towards the back wall from the upper adjusting means. - The upper clamping mechanism comprises a comfort element, located at the shoulder of the user, between one of the straps and at least one strand of the link, the comfort element comprising a damping plate, positioned at proximity of the ramp, and a distribution plate positioned near each strand of the link, the splitter plate being more rigid than the damping plate and having cutouts so that it can be deformed to fit the morphology and to the movements of the user's shoulder. - The backpack comprises a lower compression system for moving a lower portion of a back wall of the pocket towards the back wall. - The lower compression system comprises, on each side of the bag, a lower clamping mechanism, each lower clamping mechanism comprising: - a link, - two anchor points of the link with the rear wall, the distance between the points d anchoring being greater than 10 centimeters, along a lateral edge of the wall, - a lower adjustment means in which passes at least one strand of the link, the lower adjustment means being disposed on one of the straps, laterally at the level of the flanks of the user, or on a front portion, the lower adjusting means for adjusting at least the length of a strand of the link extending to the back wall from the lower adjusting means. - The lower adjustment means comprises an element whose attachment position to the shoulder strap is adjustable in height. - The pocket is removably mounted on the frame. The invention will be better understood and other advantages thereof will emerge more clearly in the light of the following description of a backpack according to the invention, given solely by way of example and with reference to the accompanying drawings in which: - Figure 1 is a side perspective view of a backpack according to the invention; - Figure 2 is a rear view of the backpack of Figure 1, from the point of view of the user carrying the bag; - Figure 3 is a front view of the backpack of Figure 1, from the point of view of the user carrying the bag; - Figure 4 is a top view of the backpack of Figure 1, partially cutaway; - Figure 5 is a perspective view and on a larger scale, in transparency, the detail V in Figure 1; - Figure 6 is an exploded perspective view of a backpack according to a variant of the invention.
    [0004] Figure 1 shows a backpack 1, for example for running, hiking or other mountain sports. In the following, the notions of "up", "down", "upper", "lower", "left", "right", "horizontal", "vertical", "forward" and "back" are defined from a user who is standing on a level ground and wearing the backpack 1 on his back. We denote X, a "vertical" geometric axis parallel to the Earth's gravity field. In the reference position, the backpack 1 extends along the axis X. Y is a horizontal geometric axis, perpendicular to the X axis, which extends from left to right. The Y axis defines a "lateral" or "transverse" direction.
    [0005] The backpack 1 comprises a storage pocket 2 fixed on a carrying device, called frame 4 in the following description, the latter comprising two straps 41 and 42 located on either side of the X axis. The storage bag 2 is centered along the X axis, in a neutral configuration, and delimits a closed interior volume for receiving a load, for example foodstuffs, a water container, sports equipment and / or or clothes. The pocket 2 extends in height between a lower end 21 and an upper end 22. The pocket may optionally include a plurality of inner compartments, as well as outer pockets. The volume of the bag 2 is delimited by a back wall 23, a rear wall 24, a right side wall 25 and a left side wall 26. The rear wall 24 may be an outer wall, as shown here or an inner wall of the pocket, intermediate wall between the dorsal wall and an outer wall. The back wall or front wall 23 is positioned on the back side of the user, and faces the back wall 24, which is positioned opposite the back of the user with respect to the contents of the pocket. The walls 23 and 24 are connected on either side by the right side walls 25 and left 26, which face each other. Right lateral edges B231 and left B232 of the dorsal wall 23 of the bag 2 materialize the separation between the back wall 23 and the side walls 25 and 26, respectively. An upper edge B233 of the dorsal wall 23 abuts the rear wall 24, on the side of the upper end 21 of the pocket 2. On the side of the lower end 22 of the pocket 2, a lower edge B234 separates the back wall 23 of the rear wall 24. Thus, the periphery of the back wall 23 is delimited by the edges B231 to B234. In this example, the back wall 23 is connected to the frame 4 only at the edges B231 to B234 of the back wall 23. The outer wall 24 has an opening 241 to access the interior volume of the pocket 2. The opening 241 here is rectilinear and extends in length in a vertical direction, parallel to the axis X and the spine of the user. The opening 241 comprises closure means, for example a slide fastener with two sliders 242 and 243, which facilitates access to the various parts of the pocket. One can then, alternatively, access only the lower, central or upper part of the pocket.
    [0006] The opening 241 is substantially horizontal when the backpack 1 is placed on the ground, on a flat horizontal surface. Thus, the side walls prevent the contents of the bag from the pocket. In addition, this construction also has the advantage of having a large access area to the interior volume of the pocket 2. This allows easy access to the objects stored at the bottom of the pocket 2, unlike a backpack of the prior art which is generally provided with a single opening on the top of the pocket. In the example shown in the figures, the walls 23 to 26 are flexible fabric panels manufactured separately and then assembled together, for example, by means of seams and / or by gluing.
    [0007] Alternatively, the walls 23 to 26 may be in one piece, or in two or three pieces. For example, the sidewalls 25 and 26 and the outer wall 24 may be formed by a single piece of tissue. The back wall 23 is made of a material having a flexibility allowing deformation of the back wall 23 to adapt to the morphology of the back of the user 10, statically or in motion. Such a material may deform at least in a direction normal to the wall without exerting a significant effort. A wall made of such a material can thus deform, without effort, so as to marry the shape it covers. This material can be a fabric, a knit, a textile, a membrane, a fabric, a very flexible foam. The wall may also comprise more rigid parts but, in this case, they must be connected by flexible connections to obtain the desired general flexibility. For a foam wall, the thickness of such a wall is preferably less than 1 cm. The foam wall may comprise foam elements of greater thickness, interconnected by very flexible elements which are deformable so as to allow the foam elements to move relative to each other. For example, the back wall 23 is made of polyamide (PA) such as Nylon®. It can be "Ripstop" of 70 deniers minimum. The side walls 25, 26 and rear 24 may be made of the same material. Alternatively, the side walls are made of composite comprising a mixture of polyamide and elastane, in proportions of about 3/4 polyamide and 1/4 elastane. Elastane provides elasticity to improve the plating of the load against the back. Each shoulder strap 41, 42 comprises a front portion 411, 412 configured to cover the front of one shoulder and one side of the chest of the user 10. Each shoulder strap 41, 42 also includes a rear portion 431, 432 configured to extend laterally behind one of the shoulders of the user 10. The straps 41 and 42 are connected transversely to each other by a connecting member 433, at the back. Thus, the rear portions 431, 432 of the shoulder straps and the connecting member 433 form a back portion 43 of the frame 4. This back portion is configured to match the shape of the back of the user. The dorsal portion 43 of the frame is distinct from the back wall 23 of the pocket.
    [0008] In the example shown in the figures, the rear portion of each shoulder strap 41, 42 is formed by a lateral band 431, 432 of the dorsal portion 43. Each front portion 411, 412 is connected to the corresponding rear portion 431, 432 of so as to form a ring configured for the passage of an arm of the user. This ring is closed permanently and not adjustable, as shown in the figures. Alternatively, the rings are open, the straps 41 and 42 being equipped with closure means such as straps, rings, hooks and / or loops, to adjust the length of the straps 41 and 42 to adapt to the user's morphology 10. The front and back portions of the straps can be made of a single material, thus forming a continuous panel. Alternatively, it may be an assembly of different panels, the same material or different material. The side strips 431 and 432 are interconnected by a central portion 433 to form a continuous panel substantially corresponding to the back portion 43 of the frame. The central portion 433 is a connecting member of the rear portions 431 and 432 of the shoulder straps 41 and 42 at the back of the user 10. The connecting member 433 can be fixed or removable. As illustrated, a panel or net can connect the rear portions 431 and 432 of the shoulder straps 41 and 42 together permanently, that is to say without being removable. The chassis then forms a unitary piece consisting of the straps and the connection element. Alternatively, the connection element is removable, that is to say, removable. It may be for example a lacing or a reported panel. The connection element can also be realized by a row of transverse strips. The dorsal portion 43 can be hollowed out locally. The chassis 4 is then in the form of a vest or a sleeveless jacket. It is made of a soft and lightweight material.
    [0009] The dorsal portion 43 is made of a material having a flexibility allowing deformation of the back wall 23 to adapt to the morphology of the back of the user 10, statically or in motion. As we have seen previously, such a material can deform at least in a direction normal to the wall without exerting a significant effort. A wall made of such a material can thus deform, without effort, so as to marry the shape it covers. This material can be a fabric, a knit, a textile, a very flexible foam. The wall may also comprise more rigid parts but, in this case, they must be connected by flexible connections to obtain the desired general flexibility. For example, the back portion 43 is made of polyester (PE) or polyamide (PA) yarn. The wall may advantageously form a net (mesh) to improve the ventilation of the back. To further improve this ventilation, the structure of the knit can be in "3D", that is to say with a thickness of a few millimeters. These knits are categorized as "spacer", often referred to as "3D mesh". It is characterized by a density of the order of 300 to 400 g / m2. The connection element 433 may be a simple net composed of polyamide or polyester yarns having a density around 200 g / m 2. The chassis 4 is equipped with transversal approach means of the front portions 411 and 412 of the shoulder straps 41 and 42, making it possible to adjust and maintain the spacing of the straps 41 and 42. For example, the clamping means comprise a link 441 of adjustable length, which connects the front portions 411 and 412 of the shoulder straps 41 and 42. The adjustment of the length of the link 441 makes it possible to adapt the backpack 1 to the corpulence of the user 10. The position of the link 441 is adjustable in height thanks to the front portions 411 and 412 of the shoulder straps 41 and 42, which are each equipped with a row of loops 442 or 443 left 441 distributed along the front portions 411 and 421. The user can choose 10 which passersby 442 and 443 he attaches the link 441, so as to adapt the backpack 1 to its corpulence. 4A is an upper end of the frame 4, and 4B, its lower end. More specifically, these ends 4A, 4B respectively delimit the upper and lower parts of the dorsal portion 43. The upper end 4A is close to the upper seam between the front portion 411 and 412 and the rear portion 431 and 432 of a strap 41 or 42. The lower end 4B is close to the lower seam between the front portion 411 and 412 and the rear portion 431 and 432 of a shoulder strap 41 or 42. When the frame 4 is placed on a flat surface, the ends 4A and 4B are substantially coplanar with this surface. In this example, the pocket 2 is permanently fixed to the frame 4 by inseparable connecting means, for example links, such as cords or straps sewn to both the frame 4 and the pocket 2. Alternatively , the connecting means are formed by permanent seams directly connecting the frame 4 to the bag 2. In the example of Figures 1 to 5, these connecting means are discontinuous and are localized punctually along the upper edge B233, edge right lateral B231 and the left lateral edge B232 of the dorsal wall 23 of the pocket 2. The connecting means comprise two right upper loops 61 and 62 left, arranged symmetrically with respect to the axis X, substantially at the junction between the neck and the shoulders. Each upper loop 61, 62 is fixed, on the one hand, at the upper edge B233 the pocket 2 and, on the other hand, at the upper end 4A of the frame 4. The loops 61 and 62 are made from straps of strap. The connecting means also comprise two lower right and left 63 loops, arranged symmetrically with respect to the X axis, substantially at the level of the lower lateral part of the back. Each lower loop 63, 64 is fixed, on the one hand, at a lateral edge B231, B232 of the pocket 2 and, on the other hand, at a rear portion 431 35 and 432 of a shoulder strap 41 or 42, or in other words, a lower rear side portion of the frame 4. The loops 63 and 64 are made from webbing sections. The first connection means comprise two right 65 and left 65 intermediate loops, arranged between a lower loop 63, 64 and an upper loop 61, 62. Each intermediate loop 65, 66 is fixed, on the one hand, at a B231, B232 lateral edge, in the middle part of the pocket 2 and, secondly, at a rear portion 431 and 432 of a shoulder strap 41 or 42, or in other words, a median rear lateral portion of the frame 4 The loops 65 and 66 are made from webbing sections. According to one embodiment, a distance D1 measured vertically between the intermediate loop 65, 66 and the upper loop 61, 62 is greater than 10 cm. Alternatively, the distance D1 is greater than 15% of the total height H23 of the dorsal wall 23. Likewise, a distance D2 measured vertically between an intermediate loop 65, 66 and the lower loop 63, 64 is greater than 10 cm. Alternatively, the distance D2 is greater than 15% of the total height H23 of the dorsal wall 23.
    [0010] Alternatively, the backpack may include more intermediate loops. In this case, the distance D measured vertically between two vertically adjacent loops is greater than 10 cm. Alternatively, this distance D is greater than 15% of the total height H23 of the back wall 23. In this example, the height H23 is substantially 40 cm.
    [0011] The hooking of the pocket 2 on the frame 4, at isolated points 61 to 66 on the periphery of the back wall 23 of the bag 2, provides a space between the back portion 43 of the carrying device 4 and the pocket 2, which promotes air circulation and limits moisture due to perspiration. Between two loops or points of attachment 61 to 66, there is no other means of connection.
    [0012] The lack of connection generates openings or passages allowing the air to circulate between the back portion 43 of the frame 4 and the back wall 23 of the pocket 2. This improves the ventilation of the back of the user. In our example, an upper passage P1, between the pocket 2 and the frame 4, is formed between the upper attachment means 61 and 62 and the intermediate attachment means 65 and 66. A lower passage P2 is provided between the means lower grips 63 and 64 and the intermediate attachment means 65 and 66. The passages P1 and P2 are free, they do not have connecting means between the bag 2 and the chassis 4. Between the hook points 61 at 66, due to the absence of other means of connection, the relative movements between the frame 4 and the pocket 2 are preserved, which promotes the freedom of movement of the user. The passages P1 and P2 therefore also have the function of allowing the vertical relative movements M1 and / or lateral M2 between the pocket 2 and the frame 4. In other words, a lateral edge B231, B232 of the back wall 43 is connected in a discontinuous manner. to the frame 4 so as to form at least one lateral zone P1, P2 without connection 35 between the lateral edge and the frame on a minimum free height D. An overlap zone Zr corresponding to a superposition zone between the back wall 23 is defined of the pocket 2 and the back portion 43 of the frame 4. By definition, the connecting means 61 to 66 are located outside the overlap zone Zr. In the example of FIGS. 1 to 5, the overlap zone Zr is delimited by the edges B231, B232, B233, B234 of the dorsal wall 23. The outlines of the overlap zone Zr are slightly set back towards the center of the dorsal wall 23 with respect to the edges B231 to B234, so as not to include the connecting means 61 to 66. This construction therefore allows vertical relative movements M1 and / or horizontal M2 between the pocket 2 and the frame 4, in the overlap zone Zr, in a direction and in the opposite direction, that is to say to the right and to the left for the horizontal movement M2, and upwards and downwards for the vertical movement M1. Preferably, they are possible both horizontally and vertically. These relative movements M1 and / or M2 result from the spacing between the attachment means 61 to 66. Other factors 10 facilitate these relative movements such as the length of the loops 61 to 66, between the seams with the pocket 2 and the chassis 4 or the flexibility of the back wall 23 and the back portion 43 of the frame. The lower and intermediate linkage means 63 to 66 are optional. In a variant of the invention, the pocket 2 is only hooked to the frame 4 by the upper connecting means 61 and 62. Other types of connecting means or hook points 61 to 66 can be envisaged. to be a direct seam between the walls, a simple piece of strap, a cord. In this embodiment, the backpack 1 is equipped with a lower compression system, which allows the plating of the load, contained in the pocket 2, against the back of the user 10. This system comprises two mechanisms lower right 9A clamping and left 9B, including passers right 91 and left 92 secured to the pocket 2. The loops form a passage sheath for a straight link 93 or left 94, for example a cord, a lace or a strap. In the example shown in the figures, the loops 91, 92 are located at the joints between the side walls 25 and 26 and the lower part of the outer wall 24 of the pocket 2. The loops 91, 92 are thus connected at the outer wall 24 of the pocket 2. Here, the loops 91 and 92 are arcuate shaped sleeves, the center of the radius of curvature is at the front of the outer wall 24 and above the lower end 22 of the pocket. The loops 91, 92 have a length L91, L92 greater than 10 cm. Each passer comprises a high end 911, 921 and a low end 912, 922. In a variant, the loops 91, 92 are connected to a rear wall of the bag 2 which is not an external wall, that is, that is to say a wall which is included in the volume of the pocket 2, for example an inner intermediate wall which separates the volume of the pocket 2 into compartments. It can also be a pocket contiguous to the rear wall. This rear wall 35 is situated rearward with respect to the rear wall 23. The links 93, 94 are each hooked on the front part 411, 412 of the corresponding ramp 41, 42, in the lower part, by first lower adjustment means comprising straight hooks 95 and left 96, integral links, cooperating with second lower adjustment means, for example right and left 98 loops, integral with the shoulder strap 41, 42. Preferably, several loops 97, 98 are distributed along the straps 41, 42, under the armpits, at different heights, to allow the user to choose the attachment height of the links 93, 94 on the frame 4. The second lower adjustment means 97, 98 are located laterally at the level of the sidewalls of the user 10, or on the front portion 411, 412 of the shoulder straps 41, 42. Thus, the attachment position of the hooks 95, 96 to the shoulder strap 41, 42 is adjustable in height, for adapt to the It also allows to adapt the tightening according to the load transported. If there is little load, we can go up the first adjustment means 95, 96 so that the load is plated higher. Repositioning the load upward improves the balance of the backpack. The center of gravity is better positioned when the user moves. When there is a heavier load, the hook 95, 96 can be lowered to increase the carry volume. The load will then be supported in an area closer to the lumbar. Each hook 95, 96 is integral with a link 93, 94. This first lower adjustment means then comprises a blocker for receiving two ends of the link 93, 94 corresponding. In this example, the link 93, 94 passes a first time by the blocker 95, 96, then connects the blocker to a lower end 912, 922 of the passer 91, 92 associated, thus forming the lower strand 932, 942, then is threaded in the loop, then connects a high end 911, 921 of the passer associated with the blocker, thus forming the lower strand 931, 941, then passes a second time of the blocker. Thus, the two free ends of the link 93, 94 leave the blocker 95, 96. By pulling on the two free ends of a link 93, 94 strands 931, 932, 941, 942 are stretched which causes the reduction of the length of the strands 931, 932, 941, 942. Consequently, when acting in this way on the two links 93, 94, brings about the bringing together of the lower part of the rear wall 24 on which are fixed the loops 91, 92 to the back portion 43 of the frame 4. In other words, to press the load contained in the pocket 2 against his back, the user hooks the hooks 95 and 96 on loops 97 and 98, then pulls on the free ends of the links 93 and 94 passing through the associated blocker 95, 96. This action has the effect of bringing the ends 911, 912, 921, 922 passers 91 and 92 and the outer wall 24 of the bag 2 to the frame 4, in the manner of hangers that act on the canvas of a paraglider. By stretching the links 93 and 94, the user 10 accentuates the curvature of the loops 91, 92, which allows to bring the load back to the center of the back and here, to raise the load upwards. The higher the load, the easier it is for the user to move because the center of gravity is also raised. This first lower compression system contributes to the stability of the load. Alternatively, the lower compression system is configured so that a single strand 931, 932, 941 or 942 of each link 93, 94 passes into each blocker 95, 96. In this case, a first end of the link 93, 94 is fixed on the front part 411, 412 of the shoulder strap 41, 42, in an area close to the second lower adjustment means, and a second end of the link 93, 94 passes through the blocker 95, 96. By pulling on this second end , a tension is caused on the strands 931, 932, 941 or 942 which produces a clamping of the load similar to that described above. This compression system incorporating loops 91, 92 is advantageous because it allows to distribute the compression force over the entire length of the passer. The load is therefore compressed more uniformly. In addition, the link can slip in the loop, which allows a self-balancing of the tension in the link. The tension may be identical in the upper strand 941 and in the lower strand 942. Alternatively, the lower compression system does not include loops 91, 92. In this case, the ends of each link 93, 94 are directly attached to the edge lateral wall of the rear wall 24, at the junction with a side wall 25, 26. To obtain the desired compression effect, the lower end of the link 93, 94 is fixed on the lower part of the rear wall 24, substantially to a similar level as the low end 912, 922 of the loop 91, 92. Similarly, the upper end of the link 93, 94 is fixed on the upper part of the rear wall 24, substantially at a similar level as the upper end 911, 921 of the loop 91, 92. The distance between the two fasteners of the ends of the link along a lateral edge of the rear wall 24 is greater than 10 cm. This design variant has a somewhat less balanced compression than the compression system described above. However, it allows a variable voltage between the strands of the link, we can then adjust a voltage differential to adapt the clamping of the load. Anchor points can be defined for this lower compression system. Each anchor point corresponds to a connection between a link 93, 94 and an element of the rear wall 24. An anchor point may therefore be an end 911, 921, 912, 922 of a passer 91, 92, as illustrated in the figures. An anchor point may also be a point of attachment of a link on the edge of the rear wall 24, as described in the alternative solution. The distance between two anchor points of the same link, along a lateral edge of the rear wall 24 is greater than 10 cm. This distance corresponds to the linear distance between the two anchoring points when the rear wall 24 is laid flat.
    [0013] The lower compression system is included in a lower zone Zci characterized by a height Hci, extending upwards from the lower end 21 of the pocket 2. Preferably, the height Hci is greater than 10 cm. Advantageously, the height Hci is greater than 15% of the total height H23 of the dorsal wall 23. In this example, the height H23 is substantially 40 cm.
    [0014] The heights Hci and H23 are measured vertically, when the pocket 2 is pressed against a vertical flat surface. The lower loops 91 and 92 extend over a minimum engagement height substantially corresponding to the height Hci of the lower zone Zci. The height Hci is the height of the portion of the loops 91 and 92 which is connected to the rear wall 24. In the example of the figures, the entire height of the loops 91 and 92 is connected to the rear wall 24. Fixing the lower end 21 of the pocket 2 on the frame can be provided only by the lower compression system. In this case, the backpack 1 does not include the lower loops 63 and 64. In this embodiment, this backpack 1 is equipped with a second upper compression system which ensures the plating of the load, contained in the pocket 2, against the back of the user 10. This second optional compression system has a similar construction to the first lower compression system.
    [0015] This second system comprises two upper clamping mechanisms on the right 8A and on the left 8B, including right loops 81 and left 82 secured to the pocket 2. Passers which form a sheath or a passage sheath for a straight 83 or left 84 for example a cord, a lace or a strap. In the example shown in the figures, the loops 81 and 82 are located at the joints between the side walls 25 and 26 and the upper part of the outer wall 24 of the pocket 2. The loops 81 and 82 are thus connected to the outer wall 24 of the pocket 2. Here, the loops 81 and 82 are arcuate sleeves, the center of the radius of curvature is at the front of the outer wall 24 and below the upper end 21 of the pocket. The loops 81, 82 have a length L81, L82 greater than 15 cm. Each loop comprises a high end 811, 821 and a low end 812, 822. In a variant, the loops 81 and 82 are connected to a rear wall of the pocket 2 which is not an outer wall. The links 83 and 84 are each hooked on the front part 411 or 412 of the ramp 41 or 42 corresponding, in the upper part, by first upper adjustment means comprising right 85 and left blockers 86, which cooperate with second means of higher settings, for example loops right 87 and left 88 which retain the blockers 85 and 86. In this example, the loops 87 and 88 form a band stitched transversely on the front portion 411 or 412 straps 41 and 42. The means of 85 and 86 may be blockers, as illustrated in the figures, a push button or other adjustment means for varying the length of the links 83, 84 between the adjusting means and the rear wall 24. The adjustment means upper 85 to 88 are disposed on one of the shoulder straps 41 or 42, at the shoulder of the user 10 or, alternatively, on the front portion 411, 412 of the shoulder strap 41, 42.
    [0016] In this example, the link 83, 84 passes a first time by the blocker 85, 86, then connects the blocker to the lower end of the passer 81, 82 associated, thus forming the lower strand 832, 842, and is then inserted into the passing, then connects the upper end of the passer associated with the blocker, thus forming the upper strand 831, 841, then passes a second time of the blocker. Thus, the two free ends of the link 83, 84 exit the blocker 85, 86. Here, the two free ends are connected by a node. By pulling on the two free ends of a link 83, 84, the blocker 85, 86 is bypassed 81, 82 and strands 831, 832, 841, 842 are simultaneously stretched. then to move the blocker 85, 86 to the passing 81, 82 corresponding. This tension also causes the length of the strands 831, 832, 841, 842 to be reduced. Consequently, when acting in this way on the two links 83, 84, the approximation of the upper part of the rear wall 24 is brought about. on which are fixed the loops 81, 82 to the dorsal portion 43 of the frame 4. In other words, to press the load contained in the pocket 2 against his back, the user pulls on the ends of the links 83, 84 and then raises the blockers 85, 86 to the loops 87, 88. This action has the effect of bringing the ends 811, 812, 821, 822 loops 81, 82 and thus the outer wall 24 of the bag 2 to the frame 4, in the manner of hangers that act on the canvas of a paraglider. By straining the links 83 and 84, the user 10 accentuates the curvature of the loops 81 and 82 which allows to bring the load back to the center of the back. Here, this reduces the upper volume extending upwards. This reduction is important for the balance of the load because it limits the sloshing of the upper part of the pocket, source of imbalance. This second superior compression system also contributes to the stability of the load. Alternatively, the upper compression system is configured so that a single strand 831, 832, 841 or 842 of each link 83, 84 passes into each blocker 85, 86. In this case, a first end of the link 83, 84 is fixed on the front portion 411, 412 of the shoulder strap 41, 42, in an area close to the second upper adjustment means, and a second end of the link 83, 84 passes through the blocker 85, 86. By pulling on this second end and by raising the blocker 85, 86 towards the passage 81, 82, a tension is caused on the strands 831, 832, 841 or 842, which produces a clamping of the load similar to that described previously. This compression system incorporating loops 81, 82 is advantageous because it allows to distribute the compression force over the entire length of the passer. The load is therefore compressed more uniformly. In addition, the link can slip in the loop, which allows a self-balancing of the tension in the link. The voltage may be identical in the upper strand 841 and in the lower strand 842. As for the lower compression system, the upper compression system may have no loops 81, 82 in which case the ends of the links are directly attached to a Lateral edge of the rear wall 24. Anchor points can be defined for this upper compression system. Each anchor point corresponds to a connection between a link 83, 84 and an element of the rear wall 24. An anchor point may therefore be an end 811, 821, 812, 722 of a passer 81, 82, as illustrated in the figures. An anchor point may also be the point of attachment of a link on the edge of the rear wall 24, as described in the alternative solution. The distance between two anchor points of the same link, along a lateral edge of the rear wall 24 is greater than 10 cm. This distance corresponds to the linear distance between the two anchor points when the rear wall 24 is laid flat. The upper compression system is included in an upper zone Zcs characterized by a height Hc, extending downwards to from the upper end 22 of the pocket 2. Preferably, the height Hcs is greater than 10 cm. Advantageously, the height Hcs is greater than 15% of the total height H23 of the back wall 23. In this example, the height H23 is substantially 40 cm. The heights Hcs and H23 are measured vertically, when the pocket 2 is pressed against a vertical flat surface.
    [0017] The upper loops 81 and 82 extend over a minimum engagement height substantially corresponding to the height Hcs of the upper zone Zcs. The height engaged Hcs is the height of the part of the loops 81 and 82 which is connected to the rear wall 24. In the example of the figures, the entire height of the loops 81 and 82 is connected to the rear wall 24.
    [0018] Figures 4 and 5 show 40A and 40B right-hand comfort elements, located at the shoulders of the user 10. Each comfort element 40A, 40B is interposed between one of the shoulder straps 41 and 42 and at least one strand 83a, 83b, 84a, 84b of the link 83 or 84. In the example of the figures, the comfort elements 40A and 40B are each interposed between one of the straps 41 and 42 and the two strands 83a and 83b or 84a and 84b links 83 and 84.
    [0019] Each comfort element 40A and 40B comprises a straight distribution plate 45A or 45B left disposed below the links 83 and 84. This is, for example, a rectangular plate having cutouts 45 oriented along an axis transverse to the shoulder straps 41 and 42, direction substantially parallel to the Y axis, to form a zigzag coil. Thus, the distribution plate 45A, 45A is here made of carbon and has a high flexural flexibility around a direction transverse to the ramp. Other forms of cutouts can be envisaged to provide this flexibility. Each distribution plate 45A and 45B can then deform to adapt to the morphology and the movements of the shoulder of the user 10. This construction of the plate provides flexural rigidity around a longitudinal direction of the ramp. This allows a better distribution of the pressure generated by the tension of the links 83, 84. The user protects against the support and friction of the links 83 and 84 against the shoulder. Moreover, thanks to its cuts, the distribution plate allows a better ventilation at the level of the supports on the shoulders. The distribution plates 45A and 45B are disposed over right damping plates 47A or left 47B, for example foam. The splitter plates 45A and 45B are stiffer than the damping plates 47A and 47B, i.e., their bending strength is greater. In a variant, a distribution plate 45A, 45B and a damping plate 47A, 47B are housed in an envelope attached to the ramp. This envelope is provided with slots to pass the links 83, 84. This envelope allows to create a comfort element 40A, 40B unit, easily interchangeable. It is thus possible to modify the dimension and damping characteristics of the comfort element according to the user. The comfort elements 40A, 408 are not specific to this backpack design and can also be applied to other types of backpacks, more conventional. These elements of comfort thus bring an additional benefit to more traditional backpacks. The plates 45A and 45B are protected and held by a straight yoke 461 and left 462 of fabric, which has openings for the passage of the links 83 and 84. Part of the links 83 and 84 passes between the distribution plate 45A or 45B and the Yoke 461 or 462. The lower and upper compression systems can improve the stability of the backpack 1 and therefore the balance of the user. The user can adjust the position of the load in the pocket 2 to refocus on the portion of the back between the shoulder blades and the top of the lumbar. Thus, it allows to load the load against a portion of the back adapted to support the load. This dorsal part includes the muscle-covered ribs such as part of the trapezius muscle and the dorsal muscle, avoiding pressing on the lumbar region. In traditional high-volume backpacks, greater than 40 liters, lumbar support is preferred. This support is suitable for walking or hiking when you carry heavy loads. The invention is more suitable for backpacks designed to carry lighter loads, less than 35 liters, and more particularly for fast movements such as mountain running, for example. By reducing the plating of the load in the area defined above, the user's freedom of movement and his performance in his movements are improved. The lower compression system has the effect of raising the center of gravity of the backpack 1. The higher compression system has the effect of reducing the volume extending upwards to reduce the unbalance effect. The compression systems act independently of one another. Each compression system helps to improve the stability of the backpack and especially for backpacks of low volume or medium volume, up to 35 liters.
    [0020] The lower and upper compression systems are not specific to this backpack design and may also apply to other types of more conventional backpacks. The lower compression system and / or the superior compression system thus provide an additional benefit to more traditional backpacks. In this example, the backpack 1 is equipped with two lateral compression systems 35 of the pocket 2, each system being disposed on one side of the pocket. Each system comprises a link 51, 55, for example a cord, a string or a strap, which passes through loops 52, 53, 56, 57. First loops 53, 57 are positioned at the junction between a side wall 25, 26 and the rear wall 24. Second loops 52, 56 are positioned at the junction between a side wall 25, 26 and the back wall 27. The first and second loops associated with a side wall are arranged so that the link 51, 55 engaged in these lateral passers-by defines a zigzag trajectory. A first end of a link 51, 55 is attached to the loop closest to the upper end 22 of the pocket. A second end of a link 51, 55 is attached to the loop closest to the lower end 21 of the pocket. In the central part of the side wall 25, 26, the system comprises a link clamping device. In the example illustrated, the clamping device comprises a blocker 54, 58 in which passes a link 51, 55, the blocker being inserted between two first loops. Each link 51, 55 passes twice through the associated blocker 54, 58 so as to form a free loop on one side of the blocker.
    [0021] Thus, when you pull on the free loop and move the blocker to increase the length of the free loop, you generate a voltage in the link 51, 55. The distance between the first and second passers decreases which leads to the compressing the load, thereby reducing the internal volume of the pocket. The clamping device, and in particular the blocker, serves to maintain the link 51 or 55 in tension.
    [0022] The lateral compression system of the bag 2 makes it possible to avoid the movements of the charge inside the bag 2 and does not hinder the opening 241 of the bag 2. In the example of the backpack 1 of the figures 1 to 5, the connecting means 61 to 66 are punctual on an edge of the dorsal wall 23. In a variant, the connecting means connect, continuously, at least a portion of the lateral edges B231 and B232 of the dorsal wall 23 of the pocket 2. However, to allow the relative movements of the bag 2 relative to the frame 4 according to the invention, the connecting means comprises an elastic member ensuring this freedom of movement sought. For example, the connecting means may comprise a zipper and an elastic band disposed between the zipper and the back wall 23 of the pocket 2 or between the zipper and the back portion 43 of the frame 4. Thus, The elastic member may be stretched so as to allow movement of the bag 2 relative to the frame 4. To obtain this property, the elastic member may be made of a material comprising elastane for these elastic properties. According to one variant, the backpack 1 comprises a removable comfort wall 3 intended to be interposed between the pocket 2 and the chassis 4. This comfort wall 3 is optional. The comfort wall 3 comes into contact with the dorsal wall 23 of the bag 2 and with the dorsal portion 43 of the frame 4. For example, the comfort wall 3 is formed by a foam plate provided with ventilation holes 32 to facilitate the ventilation of the back. In this example, the comfort wall is an EVA (ethylene-vinyl acetate) foam. Optionally, the foam plate is enveloped by a fabric cover or mesh. The comfort wall 3 can be fixed on the pocket 2 or on the frame 4, for example by means of hooks, not shown. The comfort wall 3 improves the comfort of the user 10 by providing an additional thickness between the back of the user 10 and the load carried in the backpack 1. The removable wall 3 can also serve as a pillow or carpet.
    [0023] FIG. 6 illustrates a second embodiment, similar to the construction of the first embodiment, with the difference that the pocket 2 is removably mounted on the chassis 4. The pocket 2 and the chassis 4 are thus two separate elements of the backpack 201 The pocket 2 is removably attached to the frame 4, by first connecting means 261 to 266 secured to the pocket 2, which cooperate with second connecting means 271 to 276 integral with the frame 4. Only the connecting means 262 , 264, 266, 272, 274, 276 of the left part are shown. The connecting means 261, 263, 265, 271, 273, 275 of the right part are symmetrically identical and are not shown. The location of the first connecting means 261 to 266 at the dorsal wall 23 of the bag 2 is similar to the location of the connecting means 61 to 66 described with reference to the dorsal wall 23. The first connecting means 261 to 266 can be loops, straps. The second connecting means comprise two right upper hooks 271 and 272 left, fixed at the shoulders of the user in the upper part of the rear portion 431 or 432 of the shoulder straps 41 or 42, respectively. They also include two lower right 273 and 274 left hooks, fixed at the bottom of the rear portion 431 or 432 of the shoulder straps 41 or 42, respectively. They also comprise two right intermediate hooks 275 and 276 left, fixed on either side of the dorsal portion 43 of the carrying device 4, in the middle portion of the rear portion 431 or 432 of the shoulder straps 41 or 42. Alternatively, one may consider adding intermediate hooks, adding also complementary loops on the back wall 23 of the pocket. The vertical distance D1, D2 between two first connecting means or between two second connecting means, vertically adjacent, is greater than 10 cm. This distance D1, D2 is greater than 15% of the total height H23 of the back wall 23. The removable connection means 261 to 266 and 271 to 276 are, in the example of FIG. 6, loops which cooperate with hooks. Alternatively, the removable connection means may include magnets, snaps, zippers or tape hooks.
    [0024] The frame 4 may be equipped with load storage means, for example pockets or elastic straps for storing in particular foodstuffs or receiving a water bag, bottle or flange. Thus, the backpack 1 can be used only with the chassis 4, without the pocket 2, when the user has little material to transport. The frame 4 can also be equipped with loops connected to the lower part of a strap to hang carabiners. When using the backpack 1, the user can set up the pocket 2 on the chassis 4 during an approach march, to transport for example a garment or sports equipment. Then, when the user 10 passes to a more sustained sports practice, for example running or climbing, he separates the pocket 2 of the chassis 4 to keep only the chassis 4 on his back. Thus, it can benefit from a lightweight and flexible backpack for transporting essential loads, for example a water bag or energy bars or gels. In the invention, the elements described as "flexible", in particular the pocket 2, the frame 4 and the wall 3, are designed to be deformable so as to adapt this element to the morphology of the back of the user 10, in static mode. or in motion. Thus, a flexible member bends when the user performs lateral torsion of the trunk to the right or to the left, or when he leans forwards or backwards. The flexible element adapts to the movements and morphology of the back, that is to say, it follows the curvature of the spine and remains substantially pressed against the back of the user 10 during his movements. The relative vertical movement M1 between the pocket 2 and the frame 4 allows bending forward or backward of the bust of the user. The relative horizontal movement M2 allows the torsion of the trunk, that is to say the rotation around the waist. In his sports practice, the user is commonly brought to realize a combination of these two movements. The flexibility of the back wall 23 of the pocket 2 and the back portion 43 of the frame 4 prevents rigidity when carrying the backpack, which penalizes comfort and freedom of movement. Many backpacks of the prior art have a rigid back necessary for the holding of the backpack, to prevent it from sagging. A rigid backpack has the disadvantage of not being able to follow the movements and deformations of the back of the user, and not being able to adapt to its morphology. Comfort and freedom of movement are penalized. The flexibility of the backpack 1 or 201 of the invention does not generate inadvertent movements of the backpack relative to the back of the user 10, thanks to the compression systems, particularly the lower system. This provides good stability only with the lower compression system. The invention makes it possible to obtain a good compromise between the possibility of freedom of movement of the user 10, thanks to the flexibility of the bag, and a good maintenance of the backpack 1 or 201 against the back of the user, thanks compression systems 8A, 8B, 9A and 9B.
    [0025] The invention is not limited to these embodiments. In the context of the invention, the different variants can be combined together, at least partially. The invention also extends to all the embodiments covered by the appended claims.
