Abstract

Back pack has shoulder blade pads situated on either side of reinforcing plate central zone. The back pack (1) has shoulder straps (9) and a one-piece shoulder blade support (2) with a reinforcing plate which has a central zone (3) and two lateral zones (4) with shoulder blade pads (8), e.g. foam-filled. The central zone of the support, which measures 4-6 cm wide by 8-12 cm high, is fixed to the supple material of the back (13) of the pack by hook and loop fabric or seams so it can pivot about its fixing zone. It is also slightly curved, so that the padded lateral zones project from the pack when in use.

Description

La présente invention concerne un sac à dos permettant, grâce à la structure particulière de son appui dorsal d'apporter à l'utilisateur un meilleur confort et au sac une meilleure stabilité.The present invention relates to a backpack allowing, thanks to the structure particularity of its back support to provide the user with better comfort and to the bag better stability.

Un sac à dos comporte un sac proprement dit et des moyens de portage parmi lesquels des bretelles ou sangles de suspension ainsi qu'une ceinture. Lorsque le sac est en position d'utilisation, c'est la face postérieure du sac proprement dit, dénommée par la suite dos du sac, qui est en contact avec le dos de l'utilisateur. Les bretelles de portage sont fixées en partie haute du dos du sac soit directement sur le matériau constitutif dudit dos soit éventuellement sur un dispositif central permettant le réglage en hauteur desdites bretelles, comme dans le document FR.2.668.345.A backpack includes a bag itself and means of carrying including suspenders or suspension straps and a belt. When the bag is in the use position, it is the back side of the bag itself, hereinafter called the back of the bag, which is in contact with the user's back. The carrying straps are partially attached high of the back of the bag either directly on the material of which said back is possibly on a central device allowing height adjustment said suspenders, as in document FR.2.668.345.

Le poids du sac est supporté en partie sur la zone d'appui des bretelles au niveau des épaules, quand bien même des moyens particuliers sont mis en oeuvre pour effectuer un report de charge au niveau de la ceinture. Il est certes possible de disposer des éléments de rembourrage entre la sangle formant la bretelle et l'épaule mais cela n'est pas , selon le demandeur, de nature à conférer tout le confort souhaitable à l'utilisateur.The weight of the bag is partially supported on the support area of the shoulder straps, even with special means are implemented to carry out a load transfer at the level of the belt. It is certainly possible to have padding elements between the strap forming the strap and the shoulder but this is not, according to the applicant, such as to confer all the desirable comfort on the user.

Dans le document EP.0.122.764, on a déjà proposé d'améliorer le confort au niveau du dos en équipant le sac d'appuis scapulaires rembourrés, qui sont des manchons longitudinaux garnis de matériau de rembourrage et montés coulissants sur une ou deux tiges verticales qui forment la structure de rigidification du sac. Les bretelles de portage relient les deux appuis scapulaires au sac proprement dit.In document EP.0.122.764, it has already been proposed to improve the comfort at the back by equipping the bag with shoulder supports padded, which are longitudinal sleeves lined with material of padding and sliding mounted on one or two vertical rods which form the stiffening structure of the bag. The carrying straps connect the two shoulder supports on the bag itself.

Certes le confort de l'utilisateur est en partie amélioré par le sac du document EP.0.122.764, mais cela nécessite une structure de rigidification du sac particulière, à une ou deux tiges verticales.Certainly the comfort of the user is partly improved by the bag of the document EP.0.122.764, but this requires a stiffening structure of the particular bag, with one or two vertical rods.

Le but visé par la présente invention est d'avoir un confort encore meilleur, sans l'obligation d'une telle structure de rigidification du sac.The aim of the present invention is to have further comfort better, without the obligation of such a stiffening structure of the bag.

Ce but est parfaitement atteint par le sac à dos de l'invention qui comporte de manière connue par le document EP.0.122.764 un sac proprement dit , deux appuis scapulaires rembourrés et deux bretelles de portage reliant les deux appuis scapulaires au sac proprement dit.This object is perfectly achieved by the backpack of the invention which comprises in a manner known from document EP.0.122.764 a bag proper, two padded shoulder supports and two shoulder straps portage connecting the two scapular supports to the bag itself.

De manière caractéristique, il comporte :

  • a) un élément monobloc d'appui scapulaire comportant une plaque de renforcement ayant une zone centrale et deux zones latérales qui prolongent latéralement la zone centrale de manière symétrique par rapport au plan médian du sac,
  • b) en ce que les appuis scapulaires rembourrés sont disposés dans les deux zones latérales au-dessus de la plaque de renforcement et conformés pour venir en appui sur les omoplates de l'utilisateur,
  • c) et en ce que la plaque de renforcement est fixée directement sur le matériau constituant le dos du sac uniquement par sa zone centrale, en partie haute et médiane de celui-ci.
    • Typically, it includes:
  • a) a one-piece scapular support element comprising a reinforcement plate having a central zone and two lateral zones which extend the central zone laterally symmetrically with respect to the median plane of the bag,
  • b) in that the padded shoulder supports are arranged in the two lateral zones above the reinforcement plate and shaped to come to bear on the shoulder blades of the user,
  • c) and in that the reinforcing plate is fixed directly to the material constituting the back of the bag only by its central zone, in the upper and middle part thereof.

    • Ainsi, grâce à la configuration particulière de l'invention, lorsque le sac est en position d'utilisation, l'appui en partie haute du dos se fait non seulement au niveau des bretelles elles-mêmes mais également des deux appuis rembourrés scapulaires, avec une répartition de la charge qui se fait de manière homogène sur les deux omoplates grâce à la plaque de renforcement, et ce bien que la fixation du sac se fasse uniquement au niveau de la zone centrale.Thus, thanks to the particular configuration of the invention, when the bag is in position for use, support in the upper part of the back is not only at the shoulder straps themselves but also at both padded shoulder supports, with a load distribution that is done homogeneously on both shoulder blades thanks to the plate reinforcement, even though the bag is fixed only at the level of the central area.

    Dans un mode préféré de réalisation, la fixation entre l'élément monobloc d'appui scapulaire et le sac est réalisée avec une certaine capacité de pivotement de l'élément monobloc par rapport au dos du sac, selon un axe perpendiculaire audit dos. Cette capacité de pivotement permet qu'il y ait une certaine indépendance entre les mouvements naturels du corps de l'utilisateur et ceux du sac proprement dit.In a preferred embodiment, the attachment between the element monobloc of scapular support and the bag is made with a certain capacity pivoting of the one-piece element relative to the back of the bag, according to a axis perpendicular to said back. This pivoting capacity allows there to be a certain independence between the natural movements of the body of the user and those of the bag itself.

    Dans une variante de réalisation où le dos du sac est dans une matière souple , la zone centrale de l'élément monobloc d'appui scapulaire - y compris la plaque de renforcement - est toute entière fixée à ladite matière , par exemple par couture, ou grâce à des éléments d'attache mécanique auto-agrippants, du type à crochets et à boucles, la capacité de pivotement étant obtenue grâce à la capacité de déformation de ladite matière autour de la zone de fixation. De préférence dans ce cas le dos du sac comporte au moins un élément de rigidification à faible distance d de la zone de fixation et au-dessus de celle-ci Ainsi, grâce à cet élément de rigidification , qui peut se trouver à une distance d par exemple de l'ordre de 1cm, on limite le débattement angulaire du pivotement. Cet élément de rigidification peut notamment consister dans une sangle cousue transversalement sur le tissu formant le dos du sac, ladite sangle servant de point de fixation dune poignée de préhension du sac.In an alternative embodiment where the back of the bag is made of a flexible material, the central zone of the one-piece scapular support element - including the reinforcing plate - is entirely fixed to said material, for example by sewing, or thanks to self-gripping mechanical fastening elements, of the hook and loop type, the pivoting capacity being obtained thanks to the deformation capacity of said material around the fixing zone. Preferably in this case the back of the bag comprises at least one stiffening element at a short distance d from the fixing zone and above the latter. Thus, thanks to this stiffening element, which can be located at a distance d for example of the order of 1 cm, the angular movement of the pivoting is limited. This stiffening element may in particular consist of a strap sewn transversely on the fabric forming the back of the bag, said strap serving as a point of attachment of a handle for gripping the bag.

    De manière à améliorer encore l'application des deux appuis rembourrés scapulaires sur les omoplates de l'utilisateur , la plaque de renforcement est légèrement incurvée , de sorte que les zones latérales soient légèrement écartées du dos du sac en position d'utilisation, permettant notamment une certaine circulation de l'air. Le sac lorsqu'il est rempli est généralement bombée et présente lui-même une courbure qui est à l'inverse de la courbure naturelle du dos de l'utilisateur. La configuration particulière de l'élément monobloc d'appui scapulaire respecte totalement cette différence de courbure.In order to further improve the application of the two supports padded shoulder pads on the user's shoulder blades, the reinforcement is slightly curved, so that the side areas are slightly apart from the back of the bag in the use position, allowing including some air circulation. The bag when filled is generally curved and has itself a curvature which is the opposite the natural curvature of the user's back. The particular configuration of the one-piece scapular support element fully respects this difference in curvature.

    Dans un exemple de réalisation, la plaque de renforcement est constituée d'un matériau rigide ou semi-rigide, par exemple une mousse de forte densité, qui, au niveau des deux zones latérales, est recouverte par un matériau amortisseur et aéré, constituant le rembourrage des appuis scapulaires, par exemple la superposition d'une mousse de moyenne densité et d'une mousse poreuse permettant la circulation d'air.In an exemplary embodiment, the reinforcing plate is made of a rigid or semi-rigid material, for example a foam high density, which, at the level of the two lateral zones, is covered by a damping and ventilated material, constituting the padding of the supports scapulars, for example the superposition of a medium foam density and a porous foam allowing air circulation.

    La présente invention sera mieux comprise à la lecture de la description qui va être faite de deux exemples de réalisation d'un sac à dos à élément monobloc d'appui scapulaire, illustré par le dessin annexé dans lequel :

    • La figure 1 est une vue arrière en plan du sac du premier exemple,
    • La figure 2 est une vue schématique partielle de dessus du sac du premier exemple, montrant en coupe l'élément monobloc au niveau d'un appui scapulaire , sur le dos de l'utilisateur et
    • La figure 3 est une vue schématique partielle en plan d'un second exemple de sac.
    The present invention will be better understood on reading the description which will be given of two exemplary embodiments of a backpack with a monobloc element of scapular support, illustrated by the appended drawing in which:
    • FIG. 1 is a rear plan view of the bag of the first example,
    • FIG. 2 is a partial schematic view from above of the bag of the first example, showing in section the one-piece element at the level of a shoulder support, on the back of the user and
    • Figure 3 is a partial schematic plan view of a second example bag.

    En référence à la figure 1, le sac à dos 1 de l'invention se caractérise par la présence d'un élément monobloc d'appui scapulaire 2 qui à lui seul réalise l'appui dorsal lors de la portée du sac 1 tout en étant fixé à celui-ci uniquement par une zone centrale.Referring to Figure 1, the backpack 1 of the invention is characterized by the presence of a one-piece scapular support element 2 which alone performs the back support when carrying the bag 1 while being attached to it only through a central area.

    L'élément monobloc 2 comporte trois zones distinctes , à savoir une zone centrale 3 et deux zones latérales 4, qui sont symétriques par rapport au plan passant par l'axe médian DD' de l'élément 2 et également du sac 1.The monobloc element 2 has three distinct zones, namely a central zone 3 and two lateral zones 4, which are symmetrical with respect to to the plane passing through the median axis DD 'of the element 2 and also of the bag 1.

    La zone centrale 3 est par exemple, mais de manière non exclusive, de forme rectangulaire dont les grands côtés se trouvent selon la hauteur du sac, parallèles à l'axe DD', tandis que les petits côtés 6 se trouvent sur la largeur du sac, perpendiculaires à l'axe DD'.The central zone 3 is for example, but not exclusively, rectangular in shape, the long sides of which are according to the height of the bag, parallel to the axis DD ', while the short sides 6 are on the width of the bag, perpendicular to the axis DD '.

    Chaque zone latérale 4 est destinée à venir s'appuyer sur l'omoplate de l'utilisateur lors du porter du sac à dos. Selon le premier exemple illustré à la figure 1, chacune des deux zones latérales 4 a une forme oblongue s'étendant latéralement par rapport à la zone centrale et en oblique vers le bas du sac.Each lateral zone 4 is intended to come to rest on the scapula when wearing the backpack. According to the first example illustrated in Figure 1, each of the two lateral zones 4 has an oblong shape extending laterally from the central area and obliquely towards the bottom of the bag.

    Une plaque de renforcement 7 , visible sur la figure 2, constitue la base de l'élément monobloc 2, cette plaque s'étendant à la fois dans la zone centrale 3 et dans les deux zones latérales 4 et conférant à cet ensemble monobloc 2 la configuration particulière précitée.A reinforcing plate 7, visible in FIG. 2, constitutes the base of the monobloc element 2, this plate extending both in the area central 3 and in the two lateral zones 4 and giving this set monobloc 2 the aforementioned particular configuration.

    Dans chaque zone latérale 4 est disposé un appui rembourré 8 qui vient en surélévation par rapport à la plaque de renforcement 7 ,étant destiné à venir en contact avec le dos de l'utilisateur lors du porter du sac.In each lateral zone 4 is disposed a padded support 8 which comes in elevation relative to the reinforcing plate 7, being intended to come into contact with the user's back when carrying the bag.

    Le sac à dos 1 comporte de manière connue deux bretelles de portage 9 et une ceinture 10. Les bretelles de portage 9 sont fixées non pas au sac 11 proprement dit mais à l'élément monobloc d'appui scapulaire 2 selon les bords supérieurs 12 des zones latérales 4. Dans l'exemple illustré destiné au marché européen, cette fixation est réalisée de la manière la plus éloignée possible de la zone centrale 3. Le positionnement de cette fixation peut varier en fonction de la morphologie moyenne des utilisateurs.The backpack 1 comprises in known manner two shoulder straps carrying 9 and a belt 10. The carrying straps 9 are attached not to the bag 11 proper but to the one-piece scapular support element 2 along the upper edges 12 of the lateral zones 4. In the example illustrated intended for the European market, this fixing is carried out in the most possible away from the central area 3. The positioning of this binding may vary depending on the average morphology of the users.

    Les deux bretelles 9 sont, à leur extrémité opposée fixées en partie basse du sac, à proximité de la ceinture 10.The two straps 9 are, at their opposite end partially fixed bottom of the bag, near the belt 10.

    La solidarisation du sac proprement dit 11 et de l'élément monobloc d'appui scapulaire 2 se fait au niveau de la zone centrale 3 dudit élément 2. De préférence cette fixation est réalisée ave une certaine capacité de pivotement de l'élément 2 par rapport au dos 13 du sac, selon la flèche F.The attachment of the bag itself 11 and of the monobloc element shoulder support 2 is done at the central zone 3 of said element 2. Preferably this fixing is carried out with a certain capacity of pivoting of the element 2 relative to the back 13 of the bag, according to the arrow F.

    Lorsque le dos 13 du sac est dans une matière souple , notamment un tissu, cette capacité de pivotement est obtenue très simplement par couture , ou autre moyen de fixation, de tout ou partie de la zone 3 de l'élément monobloc 2 sur ladite matière constitutive du dos 13. En effet c'est la déformation naturelle de la matière souple qui permet ce pivotement.When the back 13 of the bag is made of a flexible material, in particular a fabric, this pivoting capacity is obtained very simply by sewing, or other means of attachment, of all or part of zone 3 of the one-piece element 2 on said material constituting the back 13. Indeed, it is the natural deformation of the flexible material which allows this pivoting.

    De préférence cependant, et de manière à limiter cette déformation, il est préférable , comme dans l'exemple illustré , de rigidifier la portion du dos 13 qui se trouve à proximité de la zone de fixation . Il peut s'agir par exemple, d'une sangle 14 cousue transversalement en partie haute du dos 13 , à faible distance et parallèlement au petit côté supérieur 6 de la zone centrale 3. Cette sangle peut servir au blocage d'une poignée 15 de préhension du sac 1. La déformation de la matière souple au-dessus de la zone de fixation est donc moins importante que celle qui se trouve en-dessous de la zone de fixation de sorte que l'on obtient un débattement angulaire d'angle réduit préférablement centré sur l'axe DD' au niveau de l'élément de rigidification 14.Preferably however, and in order to limit this deformation, it is preferable, as in the example illustrated, to stiffen the portion of the back 13 which is located near the fixing zone. It can be by example, a strap 14 sewn transversely at the top of the back 13, at a short distance and parallel to the small upper side 6 of the zone central 3. This strap can be used to lock a handle 15 of gripping the bag 1. The deformation of the flexible material above the fixing area is therefore less important than the one below of the fixing area so that we get a clearance angular angle reduced preferably centered on the axis DD 'at the level of the stiffening element 14.

    Comme illustré à la figure 2, la plaque de renforcement 7 est de préférence incurvée, au moins selon les deux zones latérales 4, de manière à ce que l'élément monobloc 2 épouse sensiblement la courbure naturelle du dos et à ce que les appuis scapulaires 8 soient en contact, de manière homogène sur toute leur surface, avec le dos de l'utilisateur au niveau des omoplates.As illustrated in FIG. 2, the reinforcing plate 7 is of preferably curved, at least along the two lateral zones 4, so as to that the one-piece element 2 substantially follows the natural curvature of the back and the shoulder supports 8 are in contact, so homogeneous over their entire surface, with the user's back at the level of shoulder blades.

    Le rembourrage des appuis scapulaires 8 est obtenu grâce à de la mousse venant en élévation par rapport à la plaque de renforcement 7. Il peut s'agir d'une superposition de plusieurs couches de mousse de structure différente, par exemple une première couche 16 de mousse de moyenne densité , en contact avec la plaque de renforcement 7 et une seconde couche 17 d'une mousse de faible densité à pores ouverts.The padding of the scapular supports 8 is obtained thanks to foam coming in elevation relative to the reinforcing plate 7. It can be a superposition of several layers of structural foam different, for example a first layer 16 of medium foam density, in contact with the reinforcement plate 7 and a second layer 17 of low density open pore foam.

    La plaque de renforcement 7 et les couches de mousse 16,17 sont disposées dans une enveloppe 18, l'ensemble constituant l'élément monobloc d'appui scapulaire 2. De préférence cette enveloppe 18 est perforée au niveau de la seconde couche de mousse 17, de manière à permettre le passage de l'air, ce qui crée une certaine ventilation des appuis scapulaires et l'élimination de la sueur qui pourrait être absorbée lors du porter.The reinforcement plate 7 and the layers of foam 16.17 are arranged in an envelope 18, the assembly constituting the element monobloc of scapular support 2. Preferably this envelope 18 is perforated at the second foam layer 17, so that allow the passage of air, which creates a certain ventilation of the supports scapulars and the elimination of sweat that could be absorbed during carry.

    La plaque de renforcement 7 doit être suffisamment rigide d'une part pour réaliser le transfert de charge entre la zone centrale fixée au dos du sac et les bretelles fixées aux zones latérales et d'autre part réaliser un pivotement homogène de l'ensemble monobloc 2 par rapport au sac. Cependant il n'est pas nécessaire qu'elle soit totalement rigide , pouvant fléchir légèrement selon la flèche G.The reinforcing plate 7 must be sufficiently rigid on the one hand to transfer the load between the central area attached to the back of the bag and the straps attached to the side areas and on the other hand realize a homogeneous pivoting of the monobloc assembly 2 with respect to the bag. However, it does not have to be completely rigid, capable of flex slightly according to arrow G.

    Sur la figure 2 on a représenté le positionnement de l'élément monobloc 2 lors du porter du sac 1. L'appui dorsal se fait exclusivement selon les zones latérales 4 de l'élément monobloc 2, la courbure de la plaque de renforcement 7 permettant d'avoir , pour cet appui dorsal, une répartition homogène sur toute cette surface. On peut remarquer que le sac 1, lorsqu'il est rempli, prend une forme bombée qui est à l'inverse de la forme courbe du dos 19 de l'utilisateur, de sorte qu'il y a un espace libre 20 qui se dégage entre le sac et l'élément monobloc 2 de part et d'autre de la zone de fixation 3, apte à permettre la ventilation du dos du porteur par circulation d'air.In Figure 2 there is shown the positioning of the element monobloc 2 when carrying the bag 1. The back support is made exclusively according to the lateral zones 4 of the monobloc element 2, the curvature of the plate reinforcement 7 allowing to have, for this back support, a distribution homogeneous over this entire surface. We can notice that the bag 1, when is filled, takes a domed shape which is the opposite of the curved shape of the back 19 of the user, so that there is a free space 20 which emerges between the bag and the one-piece element 2 on either side of the attachment zone 3, able to allow ventilation of the back of the wearer by air circulation.

    La largeur maximale de l'élément monobloc 2 peut être supérieure à la largeur du dos 13, notamment dans le cas d'un sac de plus petit volume.The maximum width of the monobloc element 2 can be greater than the width of the back 13, in particular in the case of a bag of smaller volume.

    La fixation de la zone centrale 3 sur le dos 13 du sac 1 a été réalisée par couture, selon les quatre côtés 5, 6 de la zone centrale 3 et également selon les deux diagonales du rectangle correspondant. Cette fixation par couture peut être facilement réalisée selon les deux petits côtés 6 au niveau de l'enveloppe 18. Selon les deux grands côtés et selon les diagonales, il est nécessaire également de coudre la plaque de renforcement. Ceci peut être obtenu par l'utilisation d'une plaque en mousse de haute ou moyenne densité, dont la rigidité est cependant suffisante pour obtenir l'effet technique recherché.The central zone 3 was fixed on the back 13 of the bag 1 by sewing, along the four sides 5, 6 of the central zone 3 and also along the two diagonals of the corresponding rectangle. This fixation by sewing can be easily done on two short sides 6 at the level of the envelope 18. According to the two long sides and along the diagonals, it is also necessary to sew the reinforcement plate. This can be obtained by the use of a high or medium foam plate density, the rigidity of which is however sufficient to obtain the technical effect research.

    Le second exemple de réalisation d'un sac 20 conforme à l'invention est illustré partiellement à la figure 3 qui représente essentiellement un élément monobloc d'appui scapulaire 21 ayant une configuration différente de celle du premier exemple. Cet élément monobloc 21 comporte comme précédemment une partie centrale 22, de forme rectangulaire dont les grands côtés 23 sont orientés longitudinalement selon l 'axe médian DD' du sac tandis que les petits côtés 24 sont orientés transversalement au même axe DD'. Dans un mode préféré de réalisation, cette zone centrale 22 par l'intermédiaire de laquelle l'élément monobloc 21 est fixé au dos 25 du sac 20, a des grands côtés 23 faisant de l'ordre de 8 à 12cm et des petits côtés 24 faisant de l'ordre de 4 à 6cm.The second embodiment of a bag 20 according to the invention is partially illustrated in Figure 3 which essentially represents a one-piece shoulder support 21 having a different configuration from that of the first example. This one-piece element 21 has as previously a central part 22, of rectangular shape whose large sides 23 are oriented longitudinally along the median axis DD 'of the bag while the short sides 24 are oriented transversely to the same axis DD '. In a preferred embodiment, this central zone 22 by through which the one-piece element 21 is fixed to the back 25 of the bag 20, has long sides 23 of the order of 8 to 12 cm and short sides 24 making the order of 4 to 6cm.

    Les zones latérales 26 de l'élément monobloc 21 s'étendent latéralement de part et d'autre de la zone centrale 22 avec un prolongement vers le haut du sac, prolongement dont une partie extrême 26a fait office de bretelle de portage.The lateral zones 26 of the monobloc element 21 extend laterally on either side of the central zone 22 with an upward extension of the bag, an extension of which an end portion 26 has served as a carrying strap.

    Dans chaque zone latérale 26, l'appui scapulaire rembourré 27 a une forme oblongue qui s'étend sur la zone latérale 26 , y compris dans le prolongement vers le haut de celle-ci jusqu'à la partie extrême 26a.In each lateral zone 26, the padded shoulder support 27 has an oblong shape which extends over the lateral zone 26, including in the upward extension thereof to the end part 26 a .

    La plaque de renforcement s'étend sur toute la surface de l'élément monobloc 21 y compris dans les parties extrêmes 26a formant bretelles de portage. Vers la pointe 28 de chaque partie extrême 26a est prévue une boucle 29 permettant la fixation d'une sangle apte à relier l'élément monobloc 21 au sac proprement dit, en partie basse de celui-ci. Les parties extrêmes 26a peuvent également comporter un rembourrage.The reinforcing plate extends over the entire surface of the one-piece element 21 including in the end parts 26 a forming carrying straps. Towards the tip 28 of each end portion 26 has a loop 29 is provided for attaching a strap adapted to connect the one-piece element 21 to the bag itself, in the lower part thereof. The end portions 26 a may also include padding.

    La fixation de l'élément monobloc d'appui scapulaire 21 sur le dos 25 du sac 20 est obtenue, dans le mode de réalisation illustré à la figure 3, par des éléments d'attache mécanique du type auto-agrippant, à crochets et à boucles. Plus particulièrement la zone centrale 22 de l'élément monobloc 21 comporte extérieurement des éléments à boucles , notamment par couture sur l'enveloppe extérieure de l'élément monobloc 21 d'une bande textile à boucles 30 à la fois sur la face extérieure et la face intérieure de l'élément monobloc 21 dans la zone centrale 22 de celui-ci.Fixing the one-piece shoulder support element 21 on the back 25 of the bag 20 is obtained, in the embodiment illustrated in FIG. 3, by mechanical fastening elements of the hook-and-loop type, with hooks and loops. More particularly the central zone 22 of the one-piece element 21 has external elements with loops, in particular by sewing on the outer casing of the monobloc element 21 of a textile strip with 30 loops on both the outside and the inside of the element monoblock 21 in the central zone 22 thereof.

    Par ailleurs, dans la partie haute et médiane du dos 25 du sac, correspondant à la zone de fixation entre ledit dos 25 et l'élément monobloc 21, sont prévus des éléments à crochets. Dans l'exemple illustré à la figure 3, il s'agit d'une bande 31 dont la longueur L est sensiblement trois fois plus importante que le grand côté 23 de longueur I1 , de la zone rectangulaire centrale 22. Par contre cette bande 31 a la même largeur I2 que le petit côté 24 de la zone centrale 22. Cette bande 31 qui présente sur sa face extérierue des crochets et sur sa face intérieure des boucles est cousue sur le dos 25 du sac uniquement dans sa partie intermédiaire 31c qui correspond à la surface de la zone centrale 22. Les deux bouts 31a et 31b, non cousus sur le dos 25 du sac, de cette bande 31 sont donc libres.Furthermore, in the upper and middle part of the back 25 of the bag, corresponding to the fixing zone between said back 25 and the one-piece element 21, hook elements are provided. In the example illustrated in FIG. 3, it is a strip 31, the length L of which is substantially three times greater than the long side 23 of length I 1 , of the central rectangular area 22. On the other hand, this strip 31 has the same width I 2 as the short side 24 of the central zone 22. This band 31 which has hooks on its outer face and loops on its inner face is sewn on the back 25 of the bag only in its intermediate part 31 c which corresponds to the surface of the central zone 22. The two ends 31 a and 31 b , not sewn on the back 25 of the bag, of this strip 31 are therefore free.

    La fixation de l'élément monobloc 21 d'appui scapulaire sur le sac est réalisée en appliquant la zone centrale 22 sur la partie cousue intermédiaire 31c de la bande 31 de sorte que les boucles disposées sur la face intérieure de la zone centrale 22 viennent coopérer avec les crochets portés par la partie intermédiaire 31c de la bande 31.Fixing the one-piece member 21 of shoulder support on the bag is carried out by applying the central zone 22 of the stitched intermediate portion 31c of the tape 31 so that the loops disposed on the inner face of the central region 22 come cooperate with the hooks carried by the intermediate part 31c of the band 31.

    Le bout inférieur 31b de la bande 31 est relevé vers la zone centrale 22 en sorte que les crochets portés par ce bout 31b coopèrent avec les boucles extérieures portées par la bande 30 recouvrant la zone centrale 22. Le bout supérieur 31a est ensuite abaissé pour recouvrir à son tour le bout intérieur 31b. La bande 31 étant pourvue de boucles sur sa face intérieure, les crochets portés par le bout supérieur 31a viennent coopérer avec lesdites boucles pour obtenir le blocage en position définitif de la zone centrale 22 de l'élément monobloc d'appui scapulaire 21 sur le dos 25 du sac 20. Le retrait de cet élément se fait en effectuant les opérations strictement en sens inverse.The lower end 31 b of the strip 31 is raised towards the central zone 22 so that the hooks carried by this end 31 b cooperate with the outer loops carried by the strip 30 covering the central zone 22. The upper end 31 a is then lowered in turn to cover the inner end 31 b . The band 31 being provided with loops on its inner face, the hooks carried by the upper end 31 a cooperate with said loops to obtain the locking in the final position of the central zone 22 of the one-piece scapular support element 21 on back 25 of the bag 20. The removal of this element is done by carrying out the operations strictly in reverse.

    Ce mode de fixation permet que ne soit pas solidarisé définitivement l'élément monobloc d'appui scapulaire au sac proprement dit, de sorte qu'il est possible lors de la vente du sac à dos de proposer à l'utilisateur de faire lui-même l'assemblage de son sac en sélectionnant tel type d'élément monobloc d'appui scapulaire qui lui convient plus ou tel type de sac proprement dit.This method of attachment means that it is not permanently attached the one-piece scapular support element to the bag itself, so that it is possible when selling the backpack to offer the user to do himself assembling his bag by selecting such type of element monobloc of scapular support which suits him more or such type of bag well said.

    Il est précisé que le qualificatif « monobloc » signifie simplement que l'élément d'appui scapulaire est d'un seul tenant ; ce terme n'exclut pas que l'élément en question peut être réalisé à partir de plusieurs pièces indépendantes, assemblées entre elles, comme cela ressort de la description ci-dessus.It is specified that the qualifier "monoblock" simply means that the scapular support element is in one piece; this term does not exclude that the element in question can be made from several pieces independent, assembled together, as is apparent from the description above.
