DETAILED DESCRIPTION OF THE DRAWINGS

[0046] In the figures and in the remainder of the description, the same references represent identical or similar elements. In addition, the various elements are not shown to scale so as to favour the clarity of the figures. Furthermore, the various embodiments and variants are not mutually exclusive and may be combined with one another.

[0047] As illustrated in FIGS. 1 to 4, the disclosure concerns a backpack 1 comprising at least one shoulder strap 3 intended for carrying the backpack 1 by a user.

[0048] FIGS. 1, 3 and 4 illustrate in particular an embodiment in which the backpack 1 comprises two shoulder straps 3.

[0049] According to another variant not represented, the backpack 1 may also include a belt.

[0050] The backpack 1 comprises in particular a main pocket 5, an outer enclosure 11 and a fastening system 9. The shoulder straps 3, and/or the belt may constitute a carrying system secured to the main pocket 5. For example, the carrying system and the main pocket 5 are integrally formed so that the carrying system is inseparable from the main pocket 5.

[0051] The main pocket 5 is formed from a flexible material, is connected to said at least one shoulder strap 3 and comprises a reinforcement 7.

[0052] In general, the reinforcement 7 is disposed at an outer surface of the main pocket 5 intended to face the back of the user. Alternatively, the reinforcement 7 may be disposed at an inner surface of the main pocket 5.

[0053] For example, the reinforcement 7 may be integrated, attached, or secured to the constituent material the main pocket at its outer surface. According to the example represented in FIGS. 1, 3 and 4, the reinforcement 7, the outer surface of the main pocket, and the shoulder straps 3, constitute a carrying system of the backpack 1.

[0054] The reinforcement 7 may in particular be made of at least one metal or an alloy of said at least one metal. Alternatively or jointly, the reinforcement 7 may be made of a plastic material. In this manner, the reinforcement 7 may stiffen the structure of the backpack 1, especially when the backpack 1 contains a heavy load

[0055] The main pocket 5, detailed in FIG. 1, comprises an inner surface internally delimiting a first compartment located on the side opposite said at least one shoulder strap 3 with respect to the reinforcement 7.

[0056] For example, the first compartment may be attached by its outline to the periphery of the reinforcement 7.

[0057] The outer enclosure 11; illustrated in FIG. 2, is formed from a flexible material and constitutes a separate piece of the main pocket 5. The outer enclosure 11 comprises an inner surface.

[0058] Finally, the fastening system 9 is configured so that the backpack 1 may occupy a separation configuration in which the outer enclosure 11 is completely separated from the main pocket 5 and a fastening configuration in which the reinforcement 7 is secured to all or part of an outline of the outer enclosure 11.

[0059] According to one embodiment, the outer enclosure 11 is configured to fold back on itself, in particular in the separation configuration.

[0060] In this manner, it is possible to place the outer enclosure 11 in a compacted configuration, for example to store it.

[0061] It is therefore clearly understood that the main pocket 5 delimits the first compartment so as to constitute the backpack 1, in particular when it occupies the separation configuration. The outer enclosure 11 therefore makes it possible to define a second auxiliary compartment to the backpack 1. The first compartment therefore constitutes an essential compartment of the backpack 1. In other words, it is possible to constitute a backpack 1 with the main pocket 5 when the outer enclosure 11 is detached from the reinforcement 7.

[0062] Alternatively, when the outer enclosure 11 is closed on itself, it may be used as a separate bag by forming a bag on its own. Advantageously, the inner surface of the outer enclosure 11 and the reinforcement 7 may internally delimit therebetween, in the fastening configuration, a total volume in which the first compartment is entirely contained.

[0063] According to a first non-limiting variant, the fastening system 9 comprises a zip closure.

[0064] According to a second non-limiting variant, the fastening system 9 comprises at least one adhesive element with reversible attachment.

[0065] According to a third non-limiting variant, the fastening system 9 comprises at least one dome fastener.

[0066] According to a fourth non-limiting variant, the fastening system 9 comprises buckles or fasteners associated with shoulder straps or strips. The inner surface of the outer enclosure 11 and the outer surface of the main pocket 5 internally delimit therebetween, when the backpack 1 is in the fastening configuration, a second compartment separate from the first compartment, the second compartment being disposed on the side opposite the reinforcement 7 with respect to the first compartment.

[0067] According to one embodiment, the second compartment has a volume substantially greater than or equal to the volume of the first compartment.

[0068] By “substantially equal”, it should be understood that the ratio between the volume of the first compartment and the volume of the second compartment is between 0.5 and 1.

[0069] According to one embodiment, the volume of the first compartment is greater than or equal to 20 litres, and in particular greater than or equal to 25 litres, and more particularly greater than or equal to 50 litres. For example, the volume of the first compartment can be comprised between 25 litres and 50 litres.

[0070] According to a variant illustrated in FIGS. 3 and 4, the outer enclosure 11 comprises an opening system 13 configured to provide reversibly, in the fastening configuration, a passage through the outer enclosure 11 giving access to the second compartment from outside the backpack 1.

[0071] According to one embodiment, the outer enclosure 11 may comprise at least one pocket. Thus, said pockets may constitute additional storage inside the backpack 1 when the outer enclosure 11 is in the fastening configuration.

[0072] The arrangements previously described make it possible, according to the needs of the user, to modulate the capacity of the backpack 1.

[0073] Furthermore, and advantageously, the fastening system 9 may be positioned at the level of the reinforcement 7 of the main pocket 5. Thus, this makes it possible to directly transfer a mass contained in the second compartment to the reinforcement 7, which is supported by at least one shoulder strap 3, which contributes to improving the lateral support of the whole backpack 1, while increasing the volume capacity of the backpack 1.

[0074] In this manner, if a load is comprised in the first compartment and/or in the second compartment, it is distributed over the user of the backpack 1 at the level of the carrying system of the backpack 1, i.e. both at the level of the shoulder straps 3, of the outer surface of the main pocket, and of the reinforcement 7 of the backpack 1, but also at the level of a belt, or a chest strap if the backpack 1 is provided therewith.

[0075] The main pocket 5 and the outer enclosure 11 being made of a flexible material, the ratio between the volume of the first compartment and the volume of the second compartment may vary and in particular be adapted according to the load contained in each compartment. For example, the first compartment may be completely empty and the second compartment completely full. In this manner, the user of the backpack 1 can choose to distribute the load as desired between the first compartment and the second compartment.

[0076] In addition, the arrangements previously described make it possible to obtain two separate and separable, one corresponding to the main pocket 5 and the other corresponding to the outer enclosure 11 folded on itself.

[0077] It is possible to provide that in this configuration of the outer casing 11, the latter delimits an unclosed volume, that is to say open so as to communicate with the outside. Finally, when the outer enclosure 11 comprises an opening system 13, it is possible for the user of the backpack 1 to insert objects into the second compartment, in particular when the outer enclosure 11 is fastened to the reinforcement 7.
