DETAILED DESCRIPTION

(9) With reference to the depicted embodiments of FIGS. 1-8, a backpack comprises a luggage element (1a) that can be placed both on the back and in front of the torso, adjustable to the user by means of two straps that pass through his/her shoulders, each comprising a main strap (2a, 2b) attached to the top of the luggage element (1a), a strap (2c, 2d) attached to the bottom of the luggage element (la), wherein the main strap and the belt are coupled by means of an adjusting element (2e, 2f) which is attached to the main strap and wherein the belt is inserted into the adjustment element to regulate its extension.

(10) In the top of the backpack there is an inflatable element (3a) preferably attached through a flange topped by a thread pattern sewn to the structure of the luggage element (1a). In order to be filled with air, the inflatable element has a nozzle to carry out manual or automatic inflation, that is, through the introduction of air by mechanical means such as manual or electric pumps or human means, among other means unrelated to the structure of the backpack. Said inflatable element (3a) comprises two main uses: it works as a support wherein the user can rest and/or support the head and it also works as a seat for whenever the user decides to mount and seat a person on his/her shoulders, for example, an infant or child.

(11) In order to hold the legs of the person mounted on the shoulders of the user of the backpack, this comprises at least one pair of harnesses (4a, 4b) coupled to the straps (2a, 2b) of the backpack similar to clamps. Each harness closes in a circular manner and adjusts its extension using a lock (5a, 5b) of varying configuration and obvious to any person skilled in the art.

(12) Additionally, the backpack also comprises at least one pair of fasteners (6a, 6b) that are located at the back, between the straps (2a, 2b). Said fasteners each comprise two belts that run in cross-section from one strap to the other horizontally, in such a way that they engage each other by means of a lock (7a, 7b) of varying configuration and obvious to any person skilled in the art. These fasteners (6a, 6b) have the main purpose of providing safety to the child seated on the user's shoulders when the user places the backpack on his/her back, and the child is secured by the harnesses (4a, 4b) attached to the straps (2a, 2b). The fasteners (6a, 6b) limit the mobility of the straps (2a, 2b) so that there are no problems while the child is held on the inflatable element (3a). For example, the straps could move from their position on the user's shoulders and separate from each other, which would cause the child to fall derived from the backpack's bad position; it is in this situation wherein the straps retain the position of the straps on the user's shoulders. Furthermore, the fasteners (6a, 6b) distribute the stress exerted by the weight of the backpack and/or of the child, avoiding excessive load on the user's shoulders.

(13) On the surface of the back of the luggage element (la), usually corresponding to the backrest and distributed evenly, the backpack has a plurality of cushion and/or pad-type elements (8) that serve to provide rest and comfort both on the user's back and torso, depending on how the backpack is placed. The pads (8) have a soft-touch surface and are filled with a padded material, creating cushions distributed over the surface of the back of the backpack.

(14) In order to preserve the shape of the backpack, it also comprises a rigid core (9a) coupled therein, on the internal wall of the backrest. The core in turn comprises a concave structure, essentially rectangular in shape with rounded edges and made from a light material that is sufficiently rigid to keep the backpack upright. In this way, the backpack remains vertical and provides the user with additional support when securing the load in different situations of use, for example and without limitation: in case of carrying a very heavy load inside the luggage element (1a), in case of carrying an infant or child on the shoulders adjusted to the harnesses (4a, 4b) and even when the backpack is used as a resting accessory when the user places it in front of his/her torso and rests his/her head on the inflatable element (3a), wherein said inflatable element passes through a hole or slot (9b) made in the top of the core (9a).

(15) Additionally, a resting structure (10) is provided in the front part of the device to support the arms in a comfortable resting position, comprising a sleeve or bag-type horizontal tubular structure opened at two ends, in which the user can insert his/her arms.

(16) In designing the backpack, as well as the accessories thereof, it is preferable to take into account certain considerations, for example, when securing an infant or child to the backpack.

(17) Some of the considerations that have served to achieve the result proposed by the present disclosure are included, but not limited to, below. It should be clarified that the inclusion of the following information does not limit the modification of characteristics included or not included in the present specification, and that any modification and/or combination of one or more of said characteristics must be considered as an embodiment of this invention. Likewise, the combination of one or more of the following preferred embodiments should be considered within the potential scope of the invention herein disclosed.

(18) In a first preferred embodiment, the object of the backpack is to be able to carry objects and/or elements therein. Therefore, the luggage element (1a) comprises a closing element (1b) that preferably surrounds the structure of the luggage element, starting on one side, passing through the top and ending on the opposite side, wherein the closing element allows to secure content inside of said luggage element (1a). Generally, the backpack is placed on the back supported by the two straps (2a, 2b), which pass over the shoulders.

(19) In another preferred embodiment, the adjusting element (2e, 2f) comprises a buckle in which the belt (2c, 2d) is inserted and tied to the main strap (2a, 2b). The buckle is attached to said main strap preferably by means of a tie finished with a sewn pattern of thread that increases the strength of the tie.

(20) In another preferred embodiment where the user wants to rest, typically the backpack is placed in front of the users torso and has the inflatable element (3a), which serves so that the user can rest his/her head. Said element is inflated through a nozzle located on the surface of the inflatable element (3a) and communicated with the inside, to which valves, pumps or the user's mouth can be coupled in order to inflate it. To use the backpack in this way, the user must place it with the torso in a vertical position, so that, once the Inflatable element (3a) has been inflated, the user reclines his/her head on it. Following this embodiment, the user can also rest his/her arms: once the backpack is placed in front of the torso, the user can place his/her arms inside the resting structure (10) that is located at the front thereof. All this is with the aim that the user can have maximum comfort and can rest safely.

(21) In another preferred embodiment, the resting structure (10) is comprised in the structure of an outer bag (1c) of the luggage element (1a), located in the front of the backpack. The outer bag comprises a hollow structure coupled to the front face of the luggage element and a closing element (1d), for example a zipper, for the protection of small items. In the bottom of the outer bag (1c) is the resting structure (10), that is, the sleeve that comprises it crosses the outer bag from one side to the other, generating a tubular structure where the user can insert his/her arms.

(22) In another preferred embodiment, when the inflatable element (3a) is not being used, it is stored in a pocket with a closing element (3c), for example, a “zipper” type element, to facilitate the deployment and protection of said inflatable element.

(23) In another preferred embodiment where the backpack is used as an infant or child carrier, the backpack works as follows: having the Inflatable element (3a) deployed and inflated, the user places the backpack on his/her back. The inflatable element (3a) works as a seat for the child, wherein the child is seated on said inflatable element, on the shoulders of the backpack user (see FIGS. 1 and 2). The backpack also presents the pair of harnesses (4a, 4b), which are removable from the straps (2a, 2b), which surround and secure the legs and/or ankles of the seated child. In order to allow the coupling and removal of the harnesses (4a, 4b) to the backpack, the straps each comprise a cross section, from side to side across the width of the strap, which generates a pair of grooves (4c, 4d) into which the harnesses (4a, 4b) are inserted and secured. The cross section is made in such a way that when the harnesses are not coupled, the cross section is invisible; and it only becomes visible when both faces of the straps are bent and separated to give rise to the grooves (4c, 4d).

(24) In another preferred embodiment, the locks (5a, 5b, 7a, 7b) are two-part locks or clasps, each part coupled at one end of the harness or fastener to which they are attached. The two-part locks generally comprise a male part that is inserted and secured to its female counterpart, by means of mechanical pressure exerted by the material from which they are made. It will be obvious to a person skilled in the art that the configuration of the locks is variable and does not limit the scope of the present disclosure, wherein the configuration may comprise any of the following options or a different one: fastening elements, velcro elements, zippers, etc.

(25) Although the invention has been described with reference to certain preferred embodiments thereof, this is not limiting for the backpack to be used with other types of articles or devices in order to improve the comfort of the user. Furthermore, it will be apparent that various versions, variations and/or adaptations can be made without departing from the spirit and scope defined in the appended claims.
