Description

The present invention relates to a backpack, including a backpack for a sport such as hiking or running, especially in the mountains. This backpack is intended especially for athletes, such as hikers, runners, mountain climbers or fans of orientation races, climbing or cycling. For the purposes of the invention, a backpack is a carrying article provided with two straps attached to a back panel and one or more pockets, anterior (s) or dorsal (s). The straps may comprise several elements assembled via an adjustment loop or they may constitute a continuous panel with the back panel so as to form a bolero type structure. The invention also relates to purified backpacks, deprived of back pocket.

Most backpacks include a simple chest strap connecting the anterior portion of each strap. Generally, the chest strap comprises a band, often elastic, one end is fixed on a first strap and the other end is fixed on the second strap. The chest strap includes means for changing the length of the band between the two attachment points of the straps. This function is important because it allows transverse positioning of the shoulder straps so greatly improve the wearing comfort of the backpack. The chest strap also includes means for splitting the band in half or detaching one end of the strap from a strap to facilitate placement of the backpack.

In recent years, Salomon © has marketed backpack models comprising two identical independent clamping systems, one at the pectoral level and one between the sternum and the belly. Each clamping system consists of an elastic band, a first attachment element intended to be fixed on a first strap, the first attachment element being integral with the elastic band at its first end, a second hooking element intended to be fixed on a second strap, the second hooking element forming a loop for the elastic band, and a third hooking element intended to be fixed on the first strap, the third gripping element being secured to the elastic band at its second end, the third attachment element comprising an adjustment device for adjusting the position of the connection between the elastic band and the third attachment element. Thus, each elastic band forms an inclined "V" whose tip is located at the second attachment element.

These two clamping systems make it possible to wedge the straps against the body and, as a result, provide excellent support for the backpack against the body when the user moves and more particularly when running. When practicing running, the runner may wish to quickly and easily adjust the positioning of braces against his chest. The double clamping system is not optimum in terms of speed because the user must act on two independent adjustment devices and remote from each other. In addition, these adjustment systems are located in an area close to the field of view of the user which does not make it obvious the grip of a maneuvering member. Thus, in this zone, to search for two actuators and to manipulate them makes the adjustment operation inconvenient.

The object of the invention is to provide an improved adjustment system of the spacing between the front portion of a first shoulder strap of a backpack and the front portion of a second shoulder strap of the rucksack.

One goal is to provide a simple adjustment system and easy to handle.

Another purpose is to allow a quick adjustment of the spacing between the front portion of a first strap of a backpack and the front of a second ramp of the backpack.

The adjustment system is characterized in that the lower link cooperates with a second adjustment device provided on the third attachment element, at the first end of the lower link, the second adjustment device for adjusting the position the connection between the lower link and the third attachment element.

This particular construction makes it possible to group the two adjustment devices at the level of the third attachment element. Thus, because of the proximity of the actuators of the two adjustment devices, it greatly facilitates the gripping thereof. This advantage is even more pronounced when the adjustment devices are located in a difficult area of the field of view. Moreover, this approximation makes it possible to envisage the simultaneous actuation of the adjustment devices by a single simple and intuitive gesture.

In the following, the notions of "up", "down", "upper", "lower", "left", "right", "horizontal", "vertical", "forward", "backward", "prior" , "Posterior" are defined from the point of a user standing on a level ground and carrying the backpack 2 on his or her back.

The invention relates to an adjustment system 1 of a backpack 2. In the sense of the invention, a backpack is a carrying article provided with two straps 21, 22 fixed on a back panel 23, indicated by a dotted line on the figures 2 and 3 , and one or more pockets, anterior (s) or dorsal (s). Thus, a single strap, each strap and / or the back panel can carry one or more pockets. For example, according to one embodiment, the backpack has no back pocket and only includes pockets carried by the straps. Each strap 21, 22 comprises an anterior portion 211, 221 intended to cover an anterior part of the trunk of the user. In the embodiments illustrated in the figures, the straps constitute a continuous panel with the back panel so as to form a bolero-type structure. Alternatively, the straps may comprise several elements assembled via an adjustment loop for adjusting the length of the straps.

Advantageously, each front portion 211, 221 of a strap 21, 22 carries fixing elements 212, 222 for hanging the adjustment system 1. The fastening elements 212, 222 are distributed, vertically, along the strap 21, 22. In these examples, the fastening elements 212, 222 are constituted by a succession of loops made by cords sewn at the medial edge of each strap and regularly distributed over the height of the ramp. Other fasteners may be envisaged such as, for example, flexible vertical bars or perforated vertical strips.

To adjust the spacing between the anterior portion 211 of a first strap 21 and the front portion 221 of a second strap 22, the backpack 2 comprises a control system 1. This adjustment allows a good positioning and plating of the straps against the body of the user and therefore a good maintenance of the backpack, especially when the user runs.

  • un deuxième dispositif de réglage 1322 permettant d'ajuster la position relative de la liaison entre le lien inférieur 102 et le troisième élément d'accroche 13,

The figure 1 illustrates a first embodiment of such a control system 1. It comprises:

• an upper link 101 delimited by a first upper end 1011 and a second lower end 1012,
• a lower link 102 delimited by a first upper end 1021 and a second lower end 1022,
• a first attachment element 11 intended to be fixed on the first shoulder strap 21, the first attachment element 11 being integral with the upper link 101 at its first end 1011,
• a second attachment element 12 intended to be fixed on the first strap 21, the second attachment element 12 being secured to the lower link 102 at its second end 1022.
• a third attachment element 13 intended to be fixed on the first shoulder 21, the third attachment element 13 being integral with the upper link 101, close to its second end 1012, and the lower link 102, close to its first end 1021 the third attachment element comprising:
  • a first adjusting device 1321 for adjusting the relative position of the connection between the upper link 101 and the third attachment element 13, and
  • a second adjustment device 1322 making it possible to adjust the relative position of the connection between the lower link 102 and the third attachment element 13,

• un quatrième élément d'accroche 14 destiné à se fixer sur la deuxième bretelle 22, le quatrième élément d'accroche 14 formant un passant pour le lien supérieur 101,
• un cinquième élément d'accroche 15 destiné à se fixer sur la deuxième bretelle 22, le cinquième élément d'accroche 15 formant un passant pour le lien inférieur 102,

According to this first embodiment, the adjustment system also comprises:

• a fourth hooking element 14 intended to be fixed on the second strap 22, the fourth hooking element 14 forming a loop for the upper link 101,
• a fifth hooking element 15 intended to be fixed on the second strap 22, the fifth hooking element 15 forming a loop for the lower link 102,

The attachment elements 11, 12, 13, 14 and 15 are all intended to be attached to a strap 21, 22 and in particular by cooperating with a fastener 212, 222 of a strap. Within the meaning of the invention, a fastening element 11, 12, 13, 14 and 15 is fixed on a strap when the fastening element is secured in movement with the strap (if one moves the fastener element in at least one direction, it causes the movement of a portion of the strap), at least when the adjustment system is activated, that is, when at least link 101, 102 is energized. This means that the attachment element is not necessarily continuously fast moving with a strap when it is fixed on it. For example, the attachment element may be a blocker integral with a link passing through a loop (corresponding to a fastener). Thus, when pulling on the link, by exerting a tension on the link, the link slides through the loop until the blocker, secured to the link, comes up against the loop. Therefore, the blocker becomes integral with the ramp. It is then fixed on the ramp, within the meaning of the invention. Alternatively, it may be a simple node made with a link. Alternatively, the attachment element can be continuously secured to a strap when it is fixed on it.

Advantageously, as described above, each strap is provided with a plurality of fasteners distributed vertically along the strap which allows the adjustment of the vertical position of each attachment element 11, 12, 13, 14 and 15 on the shoulder straps. Thus, the user can adapt his adjustment system to his morphology and target areas where he wants a maintenance / tightening. Advantageously, the attachment elements 11, 12, 13, 14 and 15 are removably mounted on the fastening elements 212, 222 of the shoulder straps. Again, this allows a customization of the adjustment system according to its needs. This also reverses the configuration of the adjustment system so that it is versatile, suitable for right-handed and left-handed. The assembly of the adjustment system is then reversed. Thus, depending on the desired configuration, each attachment element 11-15 is mounted either on the left ramp or on the right ramp. Accordingly, in the description, the first strap 21 may be indifferently the left ramp or the right ramp. In the figures, arbitrarily, the first strap 21 designates the right ramp.

In a variant, some or all of the attachment elements 11, 12, 13, 14 and 15 are fixed non-releasably on the straps. This avoids losing a hanging element.

In this example, the lower link and / or the upper link are cords. Being in the form of cords, the links have good strength in traction while being light. They are easy to put in place and do not require a particular orientation when connected to an element of the adjustment system.

Alternatively, other types of links can be used. For example, it may be ribbons, straps or laces.

Advantageously, the lower link and / or the upper link are elastic. The elasticity provides a "dynamic" tension at the level of the connection between the straps. This allows good support while providing flexibility to not interfere with breathing. According to a variant, part of the lower link and / or part of the upper link are elastic. In indeed, it is not necessary that all the link be elastic and it may be desirable to have a little rigidity / maintenance locally. Finally, the links may not be elastic.

In the example shown, the upper link 101 and the lower link 102 form a single continuous link 10, the second end 1012 of the upper link 101 constituting the first end 1021 of the lower link 102. The upper link 101 then constitutes the upper part of the continuous link 10 while the lower link 102 constitutes the lower part of the continuous link 10. Due to this construction, the continuous link 10 forms a loop 103, at the level of the third attachment element 13, between the two adjustment devices 1321 , 1322. This loop 103 facilitates the gripping of the link 10 locally to actuate the adjustment devices 1321, 1322. In addition, this allows a simultaneous action on the adjusting devices 1321, 1322.

To improve the ergonomics of actuation, the adjustment system comprises a gripping means 104 integral with the continuous link 10, at a loop 103. The gripping means 104 may be a band folded on itself surrounding the link continuous 10 or a plastic tip surrounding or overmolded around the continuous link 10.

According to one variant, the upper links 101 and lower 102 are distinct and independent. The user can thus easily operate independently the adjustment devices 1321, 1322. Gripping means can be provided at the free ends 1012 and 1021 of the links 101 and 102.

In the following, we consider the tight part of a link 101, 102, the part of the link between the attachment element 11 and the attachment element 13 or the part of the link between the element of 13 and the gripping element 12. Similarly, the actuating part of a link 101, 102 is considered, the part extending beyond the attachment element 13. The actuating part comprises the ends 1012 and 1021 and / or the loop 103.

In this example, there are three types of attachment elements constituting the adjustment system 1. A first type of attachment element 11, 12 allows to connect an end of a link on a ramp. A second type of attachment element 14, 15 guides part of a link. This second type of fastening element comprises link guiding element 142, 152. A third type of fastening element 13 makes it possible to ensure, simultaneously or otherwise, the tension in the two links 101, 102.

The Figures 4 to 6 illustrate a construction used for the hook members 11 and 12. The end 1011; 1022 of a link 101; 102 is directly integral with the body of the attachment element 11; 12. This connection can be obtained by overmolding, bonding, welding or through a node at the end of the link, the link having previously passed through an orifice in the body of the attachment element 11; 12. The attachment element 11; 12 also includes a fastener 111; 121 in the form of hooks defining a passage for receiving a fastener 212 of a strap 21, here, in this case a loop. These hooks 111; 121 are arranged so as to disengage the fastening element of the fastening element of the strap. Other fastening solutions 111 may be envisaged; 121 to removably or non-detachably fasten the fastening element with the fastening element of the strap.

According to one embodiment, the attachment elements 11 and 12 are a particular shaping of an end 1011, 1022 of a link 101, 102. It can be a simple node. For example, the link 101, 102 passes through an eyelet forming a fastener 212, 222 of a strap and a knot is formed at the end of the link to prevent it from disengaging the eyelet. Alternatively, the end of the link can form a loop, with a noose, the strand of the loop passing through the eyelet.

According to another embodiment, the end 1011, 1022 of a link 101, 102 is directly secured to the corresponding strap, for example, by stitching. In this case, the attachment elements 11 and 12 correspond to the connecting element between the link and the shoulder strap, for example, the thread of the seam.

The Figures 7 to 9 illustrate a construction used for the attachment elements 14 and 15. Like the attachment elements 11 and 12, the attachment element 14; Comprises a fastener 141; 151 in the form of hooks defining a passage for receiving a fastening element 222 of a strap 22, here, in this case a loop. These hooks 141; 151 are arranged so as to disengage the fastening element of the fastener of the strap. Other fastening solutions 141 may be envisaged; 151 for detachably or non-detachably fastening the fastening element with the attachment element of the strap. In addition, the attachment element 14; 15 also includes a hook 142; 152 defining a passage, an open sleeve or a split sheath for receiving a portion of the clamping portion of a link 101; 102. Thus, the link 101; 102 can slide through this passage, the attachment element 14; 15 then forms a passer for the corresponding link 101; 102. The passer-by is a kind of guide for the corresponding link. This hook solution 142; 152 makes it easy to disengage the link 101; 102 of the attachment element 14; 15 to remove the connection between the front parts of the straps which facilitates the introduction or removal of the backpack. This construction is simple and light. Hooks 142; 152 remain permanently on the shoulder strap 22. When the link is disengaged from the hooking element, the adjustment system does not include a rigid piece freely flapping and likely to hinder / injure the user or to hang on. Alternatively, other solutions may be envisaged for detachably or non-detachably joining the link 101; 102 with the attachment element 14; 15. For example, it is possible to use a mouthpiece secured to a link 101; 102, intended to be assembled by clipping or magnet with the attachment element 14; 15.

Thus, the fourth attachment member comprises a guide member 142 adapted to removably receive a portion of the upper link and / or that the fifth attachment member comprises a guide member 152 adapted to receive, removably, a portion of the lower link.

The third type of construction concerns the central attachment element 13, the main object of the invention. Like the other attachment elements described above, the hooking element 13 comprises a fastener 131 in the form of hooks defining a passage for receiving a fastener 221 of a strap 21, here, in this case a loop . These hooks 131 are arranged so as to disengage the attachment element of the fastener of the strap. It is possible to envisage other fastener solutions 131 for detachably or non-detachably fastening the fastening element to the fastener element of the strap.

The particularity of this hooking element 13 comes from the fact that it supports a first adjustment device 1321 and a second adjustment device 1322.

The first adjustment device 1321 makes it possible to adjust the relative position of the connection between the upper link 101 and the third attachment element 13. It thus comprises a fixed jaw 1323 integral with the body of the attachment element 13, a movable jaw 1324 relative to the fixed jaw, an actuator 1325 integral with the movable jaw and optionally an elastic means 1326 acting on the movable jaw to move it to the fixed jaw. The first adjustment device 1321 is designed to accommodate a portion of the upper link 101, close to the end 1012, so that this portion is inserted between the fixed jaw 1323 and the movable jaw 1324. Thus, when the movable jaw 1324 is biased to move to the fixed jaw 1323, for example, through the resilient means 1326, this has the effect of jamming the upper link 101 between the jaws. This nip fixes the relative connection of the connection between the upper link 101 and the third attachment element 13. The upper link 101 is secured to the third attachment element 13. The position of the third attachment element 13 on the upper link is fixed and can not be changed without user action. This makes it possible to fix the length of the tight part of the upper link, that is to say, the part of the link between the first attachment element 11 and the third attachment element 13. Conversely, when the user acts on the actuator 1325 so as to cause the separation of the movable jaw relative to the fixed jaw, it releases the upper link which can then freely slide between the jaws. By pulling on the end 1012 of the upper link 101, the user slides the upper link inside the first adjustment device 1321 to obtain the desired length of the tightening part of the upper link, that is to say that is, the part of the link between the first attachment element 11 and the third attachment element 13. Therefore, the user can release the actuator 1325 which has the effect of bringing the jaws together, for example, thanks to by elastic means 1326. The upper link 101 is then secured again with the third attachment element 13. The first adjustment device 1321 thus allows the adjustment of the length of the clamping part of the upper link, that is to say the part of the link between the first attachment element 11 and the third attachment element 13. Consequently, it allows the adjustment of the spacing between the anterior portion 211 of a first strap 21 and the front part 221 of a e second strap 22, at the level of the upper link, when the upper link is in The user can change the tightening / plating of the backpack around his torso as he wishes.

The second adjustment device 1322 makes it possible to adjust the relative position of the connection between the lower link 102 and the third attachment element 13. The construction of this second device 1322 is similar to the first adjustment device 1321. It comprises a jaw fixed 1323 secured to the body of the attachment element 13, a movable jaw 1324 relative to the fixed jaw, an actuator 1325 integral with the movable jaw and, optionally, an elastic means 1326 acting on the movable jaw to move it to the fixed jaw. The second adjustment device 1322 is designed to accommodate a portion of the lower link 102, close to the end 1021, so that this portion is inserted between the fixed jaw 1323 and the movable jaw 1324. Thus, when the movable jaw 1324 is biased to move to the fixed jaw 1323, for example, through the resilient means 1326, this has the effect of jamming the lower link 102 between the jaws. This nip fixes the relative connection of the connection between the lower link 102 and the third attachment element 13. The lower link 102 is thus secured to the third attachment element 13. The position of the third attachment element 13 on the lower link is fixed and can not be changed without user action. This makes it possible to fix the length of the tightening portion of the lower link, that is to say, the portion of the link between the second attachment element 12 and the third attachment element 13. Conversely, when the user acts on the actuator 1325 so as to cause the separation of the movable jaw relative to the fixed jaw, the lower link is released which can then freely slide between the jaws. By pulling on the end 1021 of the lower link 102, the user slides the lower link inside the second adjuster 1322 to obtain the desired length of the clamping part of the lower link, that is, that is, the part of the link between the second gripping member 12 and the third gripping member 13. Therefore, the user can release the actuator 1325 which has the effect of bringing the jaws together, for example, thanks to the elastic means 1326. The lower link 102 is then secured to the third attachment element 13. The second adjustment device 1322 thus allows the adjustment of the length of the tightening part of the lower link, that is to say the part of the link between the second attachment element 12 and the third attachment element 13. Consequently, it allows the adjustment of the distance between the front portion 211 of a first strap 21 and the front portion221 of a second shoulder strap 22, at the lower link, when the lower link is engaged with the fifth attachment element 15. The user can change the tightening / plating of the backpack around the lower region of the trunk as he wishes.

Because the first and second adjustment devices 1321, 1322 are arranged on the third attachment element 13, this makes it possible to position the operating members of the two adjustment devices in a reduced area. The user can easily grab them for manipulation, even when they are in an area of the near field of view. Thanks to this proximity, the grip of these organs of maneuver is more intuitive and can be done to the touch, "to the blind". This advantage is all the more marked when the user wants to act simultaneously on the first and second adjustment devices 1321, 1322.

The first and second adjustment devices 1321, 1322 may be two independent devices operating autonomously. This makes it easy to obtain a differential clamping between the upper link and the lower link.

Advantageously, the first and second adjusting devices 1321, 1322 share parts in common to form a single blocker 132. This construction is more compact, lightweight with a small number of parts. It allows a simultaneous, fast and balanced adjustment of the upper and lower links. With a common actuator, the actuation of the adjustment devices is simple, ergonomic and more intuitive, especially for manipulation to the touch, "blind".

In this case, the first adjusting device and the second adjusting device form a single blocker 132 comprising two jaws 1323, 1324 between which pass the upper link 101 and the lower link 102, the two jaws being movable, one relative to the other, so that when the jaws are close together, the upper link and the lower link are wedged between the two jaws and, when the jaws are distant, the upper link and the lower link are free to slide to the inside the single blocker.

According to one embodiment, the single blocker 132 comprises an elastic means 1325 for bringing the jaws and the jaws are designed so that an action on a link in one direction away from the jaws while an action in the other direction keeps the jaws tight.

There are a multitude of technical solutions to achieve these two adjustment devices. In a non-exhaustive way, the documents US4328605 , WO200912081 or EP1495691 illustrate examples of applicable embodiments.

The figure 10 represents a first embodiment of these two adjustment devices. In this case, the single blocker 132 comprises a housing, a push button, inserted in the housing, and a spring 1326 inserted between the button and the housing. The push button comprises a transverse through hole through which the two links 101, 102 pass. The box also comprises two coaxial through-holes through which the two links 101, 102 also pass. The button and the housing are indexed so that the holes transversal can be coaxial when the button is pressed into the housing. When the button is not requested by the user, the spring pushes the button outside the housing. This movement of the button causes misalignment of the axes of the transverse holes. As a result, the links get stuck at the interface between these transverse holes. The links are solid with the housing. By pressing the button, the transverse holes tend to align which causes the release of links. These can then slide freely in the transverse holes. In this example, the actuator 1325 is made by the push button, the fixed jaw 1323 is formed by an internal edge of the coaxial transverse holes of the housing and the movable jaw 1324 is formed by an outer edge of the transverse hole of the button. The same fixed jaw and the same movable jaw are used to block the upper and lower links. This embodiment is described in the document US4328605 .

According to a first variant, the housing supports a clip in the form of hooks defining a passage for receiving a fastening element of a strap, here, in this case a loop. In a second variant, it is the housing that forms the fastener cooperating with the fastening element of a strap for fixing the attachment element 13 on the corresponding shoulder strap. For example, the housing may be a cylinder dimensioned so that it can pass through a loop / fastener, when the main axis of the loop and the main axis of the cylinder are substantially aligned, and so that it can no longer pass through the loop / fastener, when the main axis of the loop and the main axis of the cylinder are substantially perpendicular. Thus, when pulling on a link, the link is slid through the loop until the single blocker housing 132 abuts against the loop (the housing being oriented so that the main axis of the loop and the main axis of the cylinder are substantially perpendicular), thereby securing the attachment element 13 with the shoulder strap. This second variant is illustrated in figure 19 .

The Figures 11 to 13 represent a second embodiment of these two adjustment devices. The figure 11 represents a hooking element 13 incorporating a single blocker 132. The figure 12 represents a section of the single blocker 132 in a link blocking configuration while the figure 13 represents the same cut of the single blocker 132 but in a link release configuration.

In this example, the single blocker 132 comprises a body in which is formed a housing "V", bordered by two side walls 1323a, 1323b, a disc 1324, inserted into the housing, and a spring 1326, shown schematically on the figure 12 , acting on the disc to push it towards the bottom of the housing. The disk 1324 is extended by an extension 1325 projecting from the housing. The single blocker 132 is designed to accommodate a portion of the upper link 101, near the end 1012, so that this portion is inserted between a first side wall 1323a of the housing and a first edge 1324a of the disc 1324 vis-à-vis -vis the first side wall 1323a and a portion of the lower link 102, near the end 1022, so that this portion is inserted between the second side wall 1323b of the housing and a second edge 1324b of the disc 1324 vis-à-vis with respect to the second side wall 1323b. The links 101, 102 thus pass, on either side of the disc 1324. In the absence of stress on the disc 1324 and its extension 1325, the spring 1326 pushes the disc 1324 to the bottom of the housing. As a result, the links 101, 102 become wedged between the disc 1324 and a side wall 1323a, 1323b of the housing, as seen in FIG. figure 12 . When the user pulls on the extension 1325, it causes the disk 1324 to move relative to the housing so as to move the disk away from the bottom housing. The distance between the side walls 1323a, 1323b and the edges 1324a, 1324b of the disc 1324 increases, thus causing the release of the links 101, 102, as seen in FIG. figure 13 . These can then slide freely in the single blocker. In this example, the actuator 1325 is made by the extension, the fixed jaw 1323 is formed by a side wall 1323a, 1323b of the housing and the movable jaw 1324 is formed by an edge 1324a, 1324b of the disc. Unlike the previous embodiment, the upper link and the lower link are blocked in separate zones. The upper link 101 is interposed between a portion of the first side wall 1323a of the housing and a portion 1324a of the first edge of the disc vis-à-vis the first side wall. The lower link 102 is interposed between a portion of the second side wall 1323b of the housing and a portion 1324b of the second edge of the disc vis-à-vis the second side wall. Separating these two blockages improves the reliability of the single blocker by reducing the risk of entanglement of links between them and the risk of sliding one link along the other. In addition, these dissociated clamps can maintain a tightening even if one of the blockages is lacking. This embodiment is described in the document EP1495691 .

The Figures 14 to 16 represent a third embodiment of these two devices for adjusting the third attachment element 13.

As previously described, the hooking element 13 comprises a hook-shaped fastener 131 defining a passage for receiving a fastener 221 of a strap 21, here, in this case a loop. These hooks 131 are arranged so as to disengage the attachment element of the fastener of the strap. It is possible to envisage other fastener solutions 131 for detachably or non-detachably fastening the fastening element to the fastener element of the strap.

A peculiarity of this blocker is that it does not include elastic means to bring the movable jaw to the fixed jaw. This reduces the number of parts of the blocker. The blocker is robust (less wear) and easy to use.

In this example, the single blocker 132 comprises a body 1325 in which is formed a through opening 1327 delimited by two longitudinal walls 1325u, 1325v and two side walls 1325a, 1325b, and a movable jaw 1324 arranged to partially close the door. 1327. The movable jaw 1324 is adapted to translate longitudinally in the opening 1327, a longitudinal wall 1325u, 1325v to the other 1325v, 1325u. Thus, this construction makes it possible to create a passage 1327u between the movable jaw 1324 and a longitudinal wall 1325u and a passage 1327v between the movable jaw 1324 and a longitudinal wall 1325v. To define the blocker, we consider the parts "high" / "low", "upper" / "lower", with reference to the position of the blocker as represented in FIG. figure 15 . The movable jaw 1324 comprises a central longitudinal rib 1324c extending vertically, upwards, so as to define two housings disposed on either side of the rib 1324c. Each of these housings is delimited by the rib 1324c, an upper face of the jaw 1324 and a side wall 1325a, 1325b of the blocker body 1325. The single blocker 132 is designed to accommodate a portion of the upper link 101, near the end 1012, and a portion of the lower link 102, near the end 1021. For this embodiment, upstream, the upper link 101 passes through the passage 1327v, from bottom to top, then into the housing delimited by the rib 1324c, an upper face of the jaw 1324 and the side wall 1325a of the blocker body 1325 and then passes through the passage 1327u, from above down, to continue, downstream, to its end 1012. This provision is illustrated in figures 15 . Concerning the lower link 102, it passes through the passage 1327v, from bottom to top, then in the housing delimited by the rib 1324c, an upper face of the jaw 1324 and the lateral wall 1325b of the blocker body 1325 and passes then through the passage 1327u, from top to bottom, to continue to its end 1021. This provision is not illustrated but is identical to that shown in figure 15 .

In the case of a continuous link 10, the ends 1012 and 1021 are connected so as to form a loop 103 as previously seen. The loop 103 is thus made at the output of the single blocker 132, after the passage of the links 101, 102 through the passage 1327u.

The blocker blocking configuration is shown in the figure 15 . In this configuration, the body 1325 of the blocker is substantially aligned with the orientation of the links 101, 102 upstream and downstream of the blocker. At the passage 1327u, the links are bent at an angle close to 90 ° against an edge of the longitudinal wall 1325u of the body 1325 of the blocker which serves to slow the movement of the links relative to the body 1325, at this edge . Furthermore, in this connection orientation configuration, in particular upstream, the more a link is energized at its clamping part, the more it will exert a force on the movable jaw 1324 to push it towards the longitudinal wall 1325u of the 1325 body of the blocker, as represented by the arrow F at the figure 15 . This translation of the movable jaw 1324 causes pinching of the links 101, 102 respectively between a portion 1324a, 1324b of the movable jaw 1324 and a portion 1323a, 1323b of the longitudinal wall 1325u of the body 1325 of the blocker. These parts 1323a, 1323b of the longitudinal wall 1325u correspond to the fixed jaw 1323. The links are then locked, secured to the body 1325 of the blocker. The higher the tension of the tightening part of the links, the more the links are sandwiched between the jaws 1323, 1324 of the blocker. To power up the tight part of a link, it is enough to reduce the length of the tight part of the link while the backpack is worn. Therefore, the perimeter of the trunk at this level will exert a force on the tight part of the link, perpendicular to the trunk, and, as the length of the tightening part of the link is fixed, this results in an increase in the tension of the link .

The release configuration of the blocker links is illustrated in the figure 16 . Thus, to release the links, it is sufficient to rotate the body 1325 around the axis of the fastener 131 as represented by the arrow R on the figure 16 . Here, we consider that the 1325 body corresponds to the actuator of the single blocker 132. By thus lifting the actuator 1325, the links 101, 102 are reoriented relative to the blocker 132, upstream and downstream of the blocker. This new link orientation frees links at 1327u. In this configuration, the orientation of the link downstream is substantially aligned with the passage 1327u, the link is no longer retained at this level. It can therefore slide freely through the passage 1327u. Furthermore, the orientation of the link downstream relative to the movable jaw 1324 is such that the link no longer exerts a major force on the movable jaw 1324 to push it towards the longitudinal wall 1325u of the body 1325 of the blocker. There is no more pinch between the jaws 1323, 1324 of the blocker. The links are then released and can slide freely in the passages 1327u, 1327v.

To adjust the tightness of the links against the body of the user, the user switches the blocker into its release configuration, as shown in FIG. figure 16 . In a second step, it pulls on the ends 1012, 1021 of the links 101, 102 or energizes the tightening portion of the links 101, 102, until the desired length of the desired link of the tightening portions of the links is obtained, c that is, the portions of the links between the hook member 13 and the hook member 11 and the length of the desired lower link between the hook member 13 and the hook member 12 Then, it folds the actuator 1325 (movement in the opposite direction of the arrow R shown in FIG. figure 16 ) to toggle the blocker into its blocking configuration as shown in figure 15 .

Advantageously, the central rib 1324c is pierced by a transverse hole 1324d so as to attach a cord, not shown, to the movable jaw. Thus, the user can grasp the cord and pull it in a direction that makes it possible to cause the movable jaw to move away from the fixed jaw, thus freeing the links. This construction facilitates the tilting of the two adjustment devices in a release configuration by a simple gesture.

In the Figures 15 and 16 , the operation of the blocker acting on the upper link 101 is illustrated. This operation is transposed directly to the operation of the blocker acting on the lower link 102.

In this embodiment, the upper link and the lower link are blocked in separate zones. Separating these two blockages improves the reliability of the single blocker by reducing the risk of entanglement of links between them and the risk of sliding one link along the other. In addition, these dissociated clamps can maintain a tightening even if one of the blockages is lacking.

Advantageously, the first and second adjustment devices 1321, 1322 are self-tightening devices in the sense that in the absence of stress on the actuator, if the links upstream are tapped, that is to say if tension is exerted on the tight part of the links, the links between the jaws are further blocked. This secures tightening and adjustment.

According to one embodiment, if one draws on the links downstream, that is to say, at the actuating portion, one can slide the links in the blocker. This facilitates adjustment because the user does not need to act on the actuator.

Advantageously, the first and second adjustment devices 1321, 1322 are self-locking devices in the sense that in the rest position, in the absence of solicitation of the user, they block the links passing through them. This characteristic is obtained thanks to an elastic means 1326 as is the case with the first two embodiments illustrated above. Alternatively, this characteristic can be achieved by a particular construction as is the case with the third embodiment illustrated above. This specificity of the adjustment devices makes the single blocker 132 also self-locking.

The adjustment of the carrying of the backpack will now be explained through the example illustrated in the figures 2 and 3 .

At first, the user installs the adjustment system on the backpack as shown on the figure 2 . This operation consists in connecting the attachment elements 11, 12 and 13 with respectively one of the fastening elements 212 of the first strap 21 and connecting the fastening elements 14 and 15 with respectively one of the fastening elements 222 of the first 22. The connection is made via the fasteners 111, 121, 131, 141, 151 of the attachment elements 11, 12, 13, 14, 15. As previously described, each strap comprises a succession of fastening elements 212, 222 distributed vertically, along each ramp. The user then chooses the fastening elements 212, 222 on which he wants to connect the attachment elements 11, 12, 13, 14 and 15 according to his desire for comfort of porting. It can thus adjust the vertical positions of the attachment points of the adjustment system.

In this configuration, the upper link 101 and the lower link 102 are disconnected from the hook elements 14 and 15. Thus, the user can easily set up his backpack. He is not embarrassed to put on the suspenders.

In a second step, the user connects the upper link 101 with the attachment element 14 and / or the upper link 102 with the attachment element 15, according to his need, as shown in FIG. figure 3 . The connection is made via the hooks 142, 152 of the attachment elements 14, 15.

In a third step, the user grasps the loop 103 or the gripping means 104 and pulls it. Because the attachment element 13 is fixed on the first strap 21, via the fastener connection 131 / fastener 212, this traction on the upper and lower links causes the release of the links in the blocker 132. The user pull until the desired tightening / adjustment is achieved. As soon as he gets the desired setting, he releases the loop. The blocker reacts by blocking the links which makes it possible to freeze the length of the clamping part of the upper link, that is to say, the part of the link between the hooking element 13 and the hooking element 11 and the length of the clamping part of the lower link, i.e., the part of the link between the attachment element 13 and the attachment element 12. This adjustment operation is simple and intuitive. It allows fast, simultaneous, balanced and comfortable tightening. It is always possible for the user to have a dissociated clamping between the upper link and the lower link. For this, it must pull on a single strand 1012, 1021 of the loop 103 and not on the loop.

During this operation, by pulling on the ends of the links 101, 102, the user brings these first portions of the backpack together, then, in a second step, he increases the plating, the tightening of the bag. against the body of the user.

The backpack is then configured for a good wearing comfort.

To modify this holding configuration, the user acts on the actuator 1325 to release the links of the blocker 132. Therefore, it is sufficient to exert a stress on the links to relax them, to increase the length of the tight part of the upper link, that is to say, the part of the upper link between the hooking element 13 and the hooking element 11 and the length of the clamping part of the lower link, that is to say , the part of the lower link between the hooking element 13 and the hooking element 12. This thus makes it possible to adjust the spacing between the front portion 211 of a first strap 21 of the backpack 2 and the part 221 of a second shoulder strap 22 of the backpack.

To remove the backpack, the user disengages the upper link 101 of the attachment element 14 and the upper link 102 of the attachment element 15. It can then easily remove his backpack.

This first embodiment of the adjustment system comprising five attachment elements 11-15 has the advantage of being practical for the introduction and removal of the backpack. Indeed, the use of the fourth 14 and fifth attachment elements 15 fixed on the second strap 22 makes it easy to couple or uncouple the links 101, 102 with the second ramp. With a simple gesture, the user can connect a link 101, 105 with the corresponding hook element 14, 15. In this embodiment, this connection is made by means of simple hooks 141, 151.

The invention is not limited to the use of five attachment elements 11-15.

According to a second embodiment, illustrated at figure 17 , the adjustment system comprises only three attachment elements 11, 12 and 13. In this case, the third attachment element 13 is intended to be fixed on the first shoulder strap 21 while the first 11 and second attachment elements 12 are intended to be fixed on the second strap 22. This construction is simple and requires only two types of attachment elements.

According to a third embodiment, illustrated at figure 18 , the adjustment system comprises only four attachment elements 11, 12, 13 and 14. In this case, the first 11 and third attachment elements 13 are intended to be fixed on the first ramp 21 while the second 12 and fourth attachment elements 14 are intended to be fixed on the second strap 22. In this example, three types of attachment elements are used.

The adjustment system may comprise more than five attachment elements and in particular have more fastening elements similar to the fourth 14 and fifth attachment elements 15. Each link 101, 102 then forms as much zigzag as desired.

Thus, according to some embodiments, the first attachment element 11 and / or the second attachment element 12 can be connected to the second ramp 22 and therefore not necessarily to the same ramp on which the third element is connected. hook 13.

According to a variant, the attachment elements 14; 15 are directly secured to the corresponding strap, for example, by gluing or stitching. In this case, they mainly comprise a hook 142; 152. According to one embodiment, the backpack may comprise a succession of hooks / attachment elements distributed vertically along a ramp, fixed permanently on the ramp. Thus, the user can very quickly choose which of the hook elements he wishes to use in relation to his need.

As mentioned above, the adjustment system advantageously comprises at least one attachment element 14, 15 provided with a guide element 141, 151 designed to removably receive a portion of a link. This feature facilitates the connection and disconnection of a portion of a link with a strap which can facilitate the introduction and removal of the backpack.

The invention is not limited to these embodiments. It is possible to combine these embodiments.

The invention is not limited to the previously described embodiments but extends to all the embodiments covered by the appended claims.
