Description

TECHNICAL FIELD

[0001] The present disclosure relates generally to a protection device for protecting a user. Preferably, the protection device is a wearable protection device. The protection device comprises an inflatable element configured to protect a passenger, a motor vehicle rider or similar user from impacts and / or falls during sports and / or work activities and / or any other activities in the inflated condition. BACKGROUND

[0002] Known protection devices are, for example, described in European patent EP3291697B1. This device comprises an inflatable element adapted to assume a working inflated condition and a resting deflated condition. The inflatable element comprises a body made of a mesh, i.e. by weaving a mesh. The mesh body is a closed structure or at least a tubular structure which defines an internal zone, region or cavity. This internal cavity is at least partially occupied by a plurality of linking threads which connect opposite portions of the mesh body to each other. The advantage of making a single mesh body is to suppress manufacturing waste and to minimize production times; in fact, the linking threads and the mesh can be processed with a single weaving machine. The linking threads are portions of a single thread which connects opposite portions of the mesh body. In particular, the thread passes alternately and continuously between a first portion and a second portion of the mesh body.

[0003] The inflatable element also comprises a waterproof wall arranged externally which allows to suppress the inflation fluid for a certain period of time. The wall is, for example, a first sheet or wall and a second sheet or wall which are fixed to each other along their respective perimeters. The first and second sheets cover and line the mesh body on the outside or outer surface.

[0004] The inflatable element thus made, although advantageous in many respects, has the disadvantage that it does not always allow a sufficient aeration in the clothing in which it is incorporated or inserted. In particular, the inflatable element in the deflated condition can form around the body of the user a kind of bag-like structure which does not allow a sufficient passage of ventilating air. To overcome this problem, it has been proposed to fold the inflatable element in the deflated condition and to expand the inflatable element in the inflated condition and occupy a more extended position so that, when the inflatable element is in the resting and not in use, there is a minimum area with little aeration. Even this solution, although advantageous in many respects, has some drawbacks, since it is not always possible to place the inflatable element in the deflated position and, in any case, it is necessary to control the expansion of the inflatable element when inflated. SUMMARY

[0005] The technical problem underlying the present disclosure is that of providing a protection device for protecting a user and a garment comprising said personal protection device, which is able to overcome the drawbacks of the prior art and allow greater air dispersion and / or achieve further advantages.

[0006] This problem is solved by a protection device for protecting a user, a protective garment or accessory for a garment and a production method for manufacturing a protection device according to the present application.

[0007] The protection device for protecting a user according to the present disclosure comprises a net-like structure comprising a first net-like portion and a second net-like portion, wherein the first net-like portion and the second net-like portion are opposite to each other and are connected to each other by means of a plurality of linking elements so as to define one or more housing portions. Furthermore, the inflatable element comprises at least one inflatable shell body housed in an internal region between the first net-like portion and the second net-like portion, thus housed in said one or more housing portions. The inflatable shell body is preferably a simple, single-layer structure similar to a balloon. More specifically and preferably, the shell body is a flexible, preferably single-layer, extensible body made of an elastic material.

[0008] In the deflated condition, the shell body occupies a space smaller than the available space in the corresponding housing portion, so as to determine an empty region. In this way, the empty region actually defined by the net-like structure allows air dispersion when the protection device is used.

[0009] In other words, the shell body occupies a first region of the housing portion in the deflated condition and a second region of the housing portion in the inflated condition. The first region is adapted to house the inflatable element in the deflated condition, and in the deflated condition the second region is empty or free of the inflatable element. In the inflation step from the deflated condition to the inflated condition, the second region receives the inflatable element in the inflated condition and opens towards the first region to house the shell body. In fact, the shell body inflates in the housing portion as much as possible until it occupies all the available space and until it is blocked by the net-like structure and the linking elements, which substantially constrain the shell body.

[0010] In other words, the above technical problem can be solved by means of a mesh structure which internally houses a shell body which is intended to be inflated, thus inflating the mesh structure and making it an inflatable structure. The mesh structure inhibits the inflation of the shell body. The shell body in the deflated state does not form any additional layer of the protection device in the second region. The second region only houses the shell body in the inflated state and is open towards the first region to receive, for example, the inflatable element in the inflation phase from the deflated state to the inflated state.

[0011] The protection device can thus be housed in a portion of clothing. This portion can be understood as a portion of the body, such as the clothing portion worn by the chest (neck region, chest region, shoulder joint region, back and arms). This portion of clothing is made according to a predetermined textile technology which is adapted to impart certain characteristics to the clothing, such as air dispersion or having ventilation openings. Thus, when the protection device is housed in the clothing, the second region of the protection device allows ensuring the air dispersion and ventilation of the clothing.

[0012] The protection device preferably also comprises a gas source connected to the inflatable shell body for inflating the inflatable shell body between the first deflated state and the second inflated state.

[0013] The inflatable shell body is thus a flexible body which, in the inflated state, remains in this state at least once for a determined period of time. Preferably, the inflatable shell body is a body which is impermeable to the inflation gas. In this case, an exhaust valve is provided to deflate the shell body. Preferably, the shell body is a tubular body or comprises a tubular portion, preferably with high expansion capacity.

[0014] Preferably, the housing is channel-shaped to facilitate the insertion of the shell body.

[0015] As mentioned above, in the deflated state, the shell body can occupy the minimum space between the mesh portions and thus allow maximum ventilation of the garment or clothing item. A body made of a preferably very elastic and expandable material and which can ensure airtightness at least for a certain time can be used as the shell body. For example, the body is a film or membrane of latex, polyurethane, polypropylene, polyester, polyamide. Inflation occurs upon impact or when required.

[0016] When the inflatable shell body is inflated, it will preferably occupy all or almost all of the accommodation in which it is accommodated, until the linking elements are tensioned. The maximum tensioning of the linking elements determines the maximum possible distance between the first and second meshed portions. A protection device is thus obtained, in which the meshed portions and the shell body define an inflatable element, i.e. an element configured to have at least an inflated configuration and a deflated configuration at rest.

[0017] The meshed portions represent the outer side of the inflatable element and the inflatable shell body represents the inner side of the inflatable element. There is thus advantageously no external wall that can make the inflatable part too rigid. There can be a reinforcement layer that can be of minimum size.

[0018] The expression meshed structure, or preferably meshed woven structure or meshed portion, means in a broad sense an actual mesh or even a fabric, even a net structure. Alternatively, the meshed structure can be a so-called woven material or a knitted material (non-woven fabric). What is important is that the meshed structure is a perforated structure or can form a framework or cage that can be tensioned around the shell body and that allows the passage of air or other gas. The meshed structure should thus be considered as a cage structure that limits and blocks or inhibits the expansion of the shell body. Thus, by appropriately shaping the structure or body comprising two meshed portions with linking elements or by providing different lengths of the linking elements depending on their position in the cavity itself, it is possible to determine a priori the shape assumed by the inflatable element in the inflated state, both in terms of distance between the two meshes and in terms of the peripheral shape of the two meshed portions.

[0019] The meshed structure can be a structure that can be more easily customized for the user, with a wide variety of resistance, flexibility, color, type of thread and yarn, etc.

[0020] Furthermore, the term linking element means in a broad sense an element, i.e. an element that is tensioned between the two meshed portions when the inflatable shell body is inflated. The linking element can also be a thread.

[0021] Alternatively, the linking element can be a thread or fabric piece or ribbon, in other words, the linking element can be a partition wall that connects the meshed portions of the meshed structure. Said partition wall can also be tensioned. The linking elements can be arranged so that a first group of linking elements is arranged in a crossed or inclined condition with respect to a second group of linking elements.

[0022] The linking element can also be made as a thread or a basting thread.

[0023] Thus, a mesh portion with a joint structure can be provided, comprising a woven material or a knitted material (non-woven fabric). The first deflated state of the shell body corresponds to the resting deflated state of the inflatable element, and the second inflated state of the shell body corresponds to the working inflated state of the inflatable element. Thus, the first and second mesh portions, together with the linking elements, act as a cage or frame for inhibiting inflation of the inflatable shell body. The shell body in fact covers the mesh fabric structure from the inside when inflated, while the shell body is slack in the deflated state.

[0024] In other words, it should be noted that at least a partially tensioned state of the linking elements corresponds to the working inflated configuration of the inflatable element, and at least a partially relaxed state, and typically a slack state, of the linking elements and mesh structure corresponds to the resting deflated configuration of the inflatable element. Thus, in the deflated state, the shell body or shell bodies are arranged with a gap in the inner region of the mesh structure.

[0025] In this way, preferably, the entire inflatable element is tensioned when the shell body is tensioned. In this way, by appropriately calibrating the shape of the housing, the shape of the shell body, the length of the linking elements, the configuration of the mesh portion, the final shape of the inflatable element can be calculated a priori.

[0026] In the inflated state, the shell body at least partially lines the first and second mesh portions which are in contact.

[0027] The first and second mesh portions, together with the linking elements and the shell body, determine the final shape of the inflatable element. For example, the inflatable element can reach a final shape which is substantially flat and planar.

[0028] In addition, thanks to the shape control, the inflatable element can be easily coupled with other devices or protection elements independent of the inflatable element and having a shape which is conjugate to the shape of the inflatable element in the inflated state.

[0029] A further advantage is that the linking elements ensure a limited expansion of the inflatable element in the inflated state, to obtain a reduced bulk and in particular a limited thickness, and at the same time ensure adequate protection for the user.

[0030] Because the protection device is an inflatable device, this solution is particularly advantageous.

[0031] This reduced size allows the user to have less discomfort and risk in the event of accidental inflation of the inflatable element while driving the vehicle. In other words, the limited expansion of the inflatable element does not affect the control of the vehicle by the user and therefore does not represent a risk of accident.

[0032] Another advantage is that, by controlling the shape of the inflatable element, it is also possible to control (and in particular to inhibit) the amount of gas required to inflate the inflatable element.

[0033] According to a preferred aspect of the present disclosure, in order to have a structure as flat as possible, the housings are placed side by side to each other so that the portions of the shell bodies are side by side to each other in the mesh structure, or the plurality of shell bodies are side by side to each other. In other words, the mesh structure is a single piece structure comprising a plurality of housings placed side by side to each other. In order to obtain these side by side housings, the mesh structure has internal partition walls or membranes which are suitably arranged to form a plurality of housings.

[0034] The internal portions or walls can be parallel to each other to obtain a plurality of housings or channels parallel to each other within the mesh structure.

[0035] Preferably, the mesh structure comprises a plurality of channels side by side and a shell body for each channel. The channel has the function of a housing according to the present disclosure. The shell body preferably has a tubular shape. Thus, when the shell body has been arranged in the respective channel / housing, each channel has a first area occupied by the shell body and a second area which is empty and is intended for housing the shell body in the inflated state. Because the channels are placed side by side to each other, in said inflated state, the respective shell bodies are pressed against each other to form an inflated body pad having an overall flat structure.

[0036] In order to make the channels, for example, joining elements are arranged between said first mesh portion and said second mesh portion aligned in a plurality of rows of joining elements to define a plurality of side by side housings. Preferably, each row of joining elements of said plurality of rows of joining elements comprises a plurality of joining elements. The shell bodies are shaped to be arranged in the respective housings between the rows of joining elements.

[0037] According to a preferred aspect of the present disclosure, in the at least partially tensioned state, the joining elements extend along a development direction substantially perpendicular to the extension direction of the rows of joining elements. According to another preferred aspect of the present disclosure, in the at least partially tensioned state, the joining elements belonging to the same row of joining elements are arranged substantially parallel to each other.

[0038] According to a preferred aspect of the present disclosure, the inflatable shell body is hand-shaped or comb-shaped, so as to have a plurality of portions arranged between the joining elements.

[0039] In operable embodiments, the shell bodies are shaped as tubular bodies or ducts inserted between the joining elements, for example, in a serpentine manner, or are tree-shaped.

[0040] In another embodiment, a plurality of inflatable shell bodies are provided, each disposed between a mesh portion and an opposing mesh portion.

[0041] The first and second mesh portions effectively define a layer of inflatable element within which an inflatable shell body is disposed. In embodiments of this disclosure, the inflatable element includes at least a third mesh portion that overlaps with the first and second mesh portions to define a second layer of the inflatable element. Portions of the shell body can be alternately arranged between the two layers to selectively control the final shape of the inflatable element without occupying too much space between the mesh portions, thereby ensuring ventilation.

[0042] Therefore, it can be seen that the inflatable element according to this disclosure has a high degree of modularity and adaptability to the structural requirements of the protection device. Attached Figure Description

[0056] Reference is made to the accompanying drawings that show, by way of example, specific embodiments thereof. In such drawings: Figure 1 through the drawings, like reference numerals refer to like parts throughout the several views of which: Figure 10 Fig. 1 shows a view of a personal protection device according to an embodiment of the present disclosure;

[0057] The main difference between the embodiments lies in the web-like structure 11, 111 as will be described hereinafter. For identical parts having the same structure, the two protection devices keep the same reference numerals.

[0058] The personal protection device 10, 110 comprises an inflatable element 12, 112 which is capable of substantially assuming a first resting or deflated state and a second working or inflated state. The inflation method will be described in the following description.

[0059] In the embodiments of the present disclosure, the inflatable element 12, 112 can be shaped like a jacket and adapted to surround the upper region or chest of the body of a user. The inflatable element 12 can be made according to any shape.

[0060] The inflatable element 12, 112 comprises a web-like textile structure 11, 111 having a first web-like portion 18, 118 and a second web-like portion 19, 119, wherein the two web-like portions are opposite to each other.

[0061] ​​The net structure 11 can be made according to the technique described in patent application PCT / IB2009 / 055512 and in patent application PCT / IT2009 / 000547, the entire contents of both of which are incorporated herein by reference, or the net structure 111 can be made according to the technique described in patent application WO2016178143A1 or in patent application WO2017163196A1, the entire contents of both of which are incorporated herein by reference. In other words, the net structure 11, 111 is preferably a net structure made with threads and formed by a net and linking elements as described in the patent applications. The most notable difference with the patent applications is that the inflatable element described herein does not have the same outer gas containment wall described in the above patent applications.

[0062] More specifically, for example, according to the technique of patent application PCT / IB2009 / 055512, the net structure 11 comprises a first net portion 18 and a second net portion 19 joined along a circumferential portion. According to the technique of patent application WO2016178143A1, the net structure 111 comprises a first net portion 118 and a second net portion 119 as part of a net shell body made in one piece. In relation to the present patent application, the first net portion 118, 18 and the second net portion 19, 119 are opposite each other and connected to each other by a plurality of linking elements 5.

[0063] Preferably, the linking elements 5 are arranged between the first net portion 18 and the second net portion 19 in alignment in a plurality of rows 24 of linking elements 5. The arrangement in rows 24 allows a better adjustment of the arrangement of the threads and further controls the inflation of the inflatable element and forms a plurality of side-by-side housing portions. Therefore, there are housing portions of channel shape in the net structure 11, 111.

[0064] In order to better control the inflation of the inflatable element in the working condition, when the inflatable element 2 is in the inflated condition, the linking elements 5 are parallel to each other in the respective rows 24 and substantially orthogonal to the direction of the rows. Preferably, the threads are shorter in the edge regions, i.e. the length of the threads decreases as the threads approach the edge.

[0065] According to an aspect of the present disclosure, the inflatable element 12, 112 comprises an inflatable shell body 40, 42, 43 arranged in one or more housing portions between the first net portion 18, 118 and the second net portion 19, 119 and connected to the gas source 15 or inflation source. According to Figure 1In an embodiment of the application, the inflatable shell body 40 has a hand or comb shape and comprises a plurality of portions 40a of the inflatable shell body 40 interposed between the rows of linking elements 5. According to Figure 6 In an embodiment of the application, the inflatable shell body 42 has a tubular shape and is interposed between the linking elements in a serpentine manner. In an embodiment of the application, the shell body has a tree shape, i.e. it has lateral branches and is also interposed between the passages of the net-like structure 11, 111. Figure 10

[0066] The shell bodies 40, 42, 43 are in a deflated state during the rest condition of the inflatable element 2, 102 and occupy as little space as possible, thus allowing the passage of air between the net-like portions 18, 19, 118, 119. Upon inflation, the shell bodies 40, 42, 43 inflate until the linking elements and the net-like portions are tensioned and, therefore, the maximum tension of the inflatable element is obtained. The net-like fabric structure 11, 111 in the inflated state actually acts as a containment cage for the shell bodies 40, 42, 43.

[0067] It should be understood that the shell bodies 40, 42, 43 and the linking elements 5 can be selected and arranged in a suitable manner to allow the insertion of the inflatable shell bodies 40, 42, 43 and to achieve the desired final shape.

[0068] Providing the inflatable shell bodies 40, 42, 43 with a plurality of portions 40a positioned side by side between the rows of linking elements 5 allows to obtain a substantially flat final configuration of the inflatable element, since the individual portions 40a in the inflated state are forced to remain side by side, blocked by the net-like portions 18, 118, 19, 119.

[0069] In alternative embodiments, such as in the embodiment of the application in Figure 8 In an embodiment of the application, a third net-like portion 120 is provided, superimposed to the first net-like portion 118 and to the second net-like portion 119. This third net-like portion 120 allows to make a second layer of the inflatable element and, therefore, to provide the inflatable shell bodies 40, 42, 42 with a plurality of housings, as well as to allow an even greater arrangement variability of the inflatable shell body or of the portions of the inflatable shell body within the net-like fabric structure 11, 111.

[0070] The present disclosure also relates to a protective garment 50 comprising a protective device 10, 110 as defined above. The protective device 10, 110 can be housed in a cavity of the garment.

[0071] ​Therefore, the garment forms a cavity for the cover of the protection device 10, 110. For example, the cavity can be made between the outer cover and the inner layer or lining of the garment. Alternatively, again, the protection device can simply be fixed under the outer cover without a real cavity.

[0072] In use, the cover layer is placed substantially above the personal protection device. The cover layer can also be understood as a multi-layer structure.

[0073] In this case, the garment comprises an outer cover, which can also be a multi-layer structure. The outer layer of the garment can advantageously be made of a breathable material, or comprise holes or ventilation openings. In other words, and in general, the garment can be made of a breathable material and / or a material that allows air to pass through, i.e. that allows ventilation, for example said material is a perforated material or has one or more ventilation openings. In other words, the garment preferably has one or more portions made of a material suitable for allowing air to pass and / or ventilation. The main advantage of the shell body in the deflated condition occupying only a portion of the mesh structure is that the presence of the inflatable element does not affect the air passing and ventilation properties of the garment.

[0074] In this way, when the inflatable element is in the non-working condition and is not actually in use, the shell body forms an additional layer in the garment in a limited manner, only in a limited area of the garment. In the remaining part of the garment (second area of the mesh structure), the shell body does not form an additional layer. Therefore, the garment can maintain its own characteristics and technical properties, which are determined by the combination of layers chosen for making the garment, and as mentioned above, which can be suitable for ventilation or air passing. Such layers include, for example, the lining and the cover surface of the protection device.

[0075] The present disclosure also relates to a method for manufacturing a protection device 10, 110 for protecting a user.

[0076] The method comprises the following steps:

[0077] - providing an inflatable element 12, 112 configured to have an inflated configuration in working condition and a deflated configuration at rest, wherein said inflatable element 12 comprises a first mesh portion 18 and a second mesh portion 19, 119 opposite the first mesh portion 18, 119 to define at least one internal housing;

[0078] - connecting said first mesh portion 18 to the second mesh portion 19 with a plurality of linking elements 5 to define one or more internal housings;

[0079] - arranging the shell bodies 40, 42, 43 in the internal housing and preferably connecting the shell bodies 40, 42, 43 to the gas source to inflate the shell bodies in the inflated condition.

[0080] Preferably, in the deflated condition, the shell bodies 40, 42, 43 occupy a first space or first area, and wherein in said deflated condition, a second area or second space of said at least one housing is free from said shell bodies, and wherein in said inflated condition, the shell bodies expand and occupy the second area or second space.

[0081] Preferably, the step of connecting the first mesh portion 18 to the second mesh portion 19 with a plurality of linking elements 5 is performed by aligning the linking elements 5 in a plurality of rows 24 of linking elements, wherein each row 24 of linking elements 5 comprises a plurality of linking elements 5, and the shell bodies are arranged between the rows 24.

[0082] In fact, the shell bodies internally cover the mesh structure 11, 111 without the need for external waterproof walls.

[0083] With regard to inflation, in order to inflate the shell bodies 40, 42, 43 in the event of a fall and / or a slip and / or an accidental impact of the user or of the vehicle in which he / she is travelling, the protection device 10, 110 is adapted to cooperate with suitable activation means (not shown) operatively connected to, for example, a gas source 15, such as a tank of compressed cold gas, such as, for example, helium. The tank can be provided with a corresponding shut-off valve (not shown).

[0084] Alternatively, the source of inflation fluid can comprise a gas generator of the pyrotechnic or hybrid type or other type known in the prior art.

[0085] Preferably, the opening of the shut-off valve of each inflation tank is controlled by a control unit as a function of the detection of the state of the vehicle / driver system; for example, said control unit can implement a fall prediction system which allows to timely identify a fall event and reliably predict a fall by means of an acceleration sensor associated with the vehicle (or with the driver) and a processing unit which processes the signals generated by the sensor.

[0086] Alternatively, the device according to the present disclosure can also find application with an activation cable connected to the vehicle driven by the user which controls the inflation of the inflatable element upon the user moving away from the vehicle, for example after a fall or accidental impact. The use of a cable is particularly used in the field of horse riding.

[0087] In any case, the above-mentioned activation means and inflation means can be incorporated into or located externally to the protection device according to the present application.

[0088] It should be noted that the activation method, although a particularly important aspect for the effective operation of the device, will not be described further in greater detail, since it is a method substantially already known to the person skilled in the art in the field of protection from accidental impacts.

[0089] So far, the object of the present disclosure has been described with reference to the embodiments of the present disclosure. It should be understood that there can be other embodiments related to the same inventive core, all of which fall within the scope of protection of the claims provided below.
