Definitions

  • the present disclosure relates in general to a personal protection device for protecting a user, wherein the device is preferably of the type which is wearable and/or can be associated with a wearable article, such as a garment.
  • the protection device includes in particular an inflatable body which in the inflated condition, is designed to protect from impacts and/or falls a motorcycle rider or passenger or similar user, during a sporting and/or working and/or any other activity.
  • the inflatable body is designed to provide protection from the cold.
  • a known protection device is, for example, that described in European Patent EP3291697B1 .
  • Such a device includes an inflatable element designed to assume an active inflated condition and a deflated rest condition.
  • the inflatable element includes a knitted body, namely a body made by means of a knitting process.
  • Said knitted body is a closed or at least tubular structure defining an inner region or area or chamber. This inner chamber is occupied at least partially by a plurality of joining threads which connect together opposite portions of the knitted body.
  • the fact of providing a single knitted body has the advantage of limiting the manufacturing waste and minimizing the production time; in fact, the joining threads and meshes may be processed using a single knitting machine.
  • the joining threads form part of single thread connected to the opposite portions of the knitted body. In particular, the thread passes along alternate sections and continuously between a first portion and a second portion of the knitted body.
  • the inflatable element also includes sealing walls which are arranged externally and allow the inflation fluid to be contained for a predetermined period of time.
  • the walls consist, for example, of a first sheet, or first wall, and of a second sheet, or second wall, which are fixed together along respective perimetral edges.
  • Said first and second sheets made of impermeable material cover and line the knitted body on an outer side or outer surface.
  • Such a wearable protection device is known from EP2373189B1 .
  • Both the wearable devices have the advantage that they have, in the inflated condition, a flat mattress-like form which is particularly suitable and appropriate for insertion in a garment.
  • An inflatable element designed in this manner while being very advantageous from many points of view, nevertheless has the drawback that it covers the body also in the deflated condition and does not always allow suitable breathability in the article of clothing in which it is incorporated or inserted.
  • the inflatable element in the deflated condition may create a kind of bag around the user's body which does not allow a suitable throughflow of ventilation air.
  • a technical problem underlying the present disclosure is that of providing a protection device for protecting a user, which is configured in such a way that the inflatable body is able to maintain in the inflated condition a substantially mattress-like - and therefore substantially flat - form and at the same time is able to overcome the drawbacks of the prior art and which ensures a greater breathability and/or achieves further advantages.
  • the personal protection device includes a mattress body including a plurality of inflatable elements arranged adjacent in sequence, wherein each inflatable element has an elongated envelope - preferably substantially tubular - shape so as to define an internal chamber which is channel-like, namely shaped in the manner of a channel.
  • the mattress body is designed to assume a first rest configuration in which the inflatable elements are in a deflated condition close to or stacked on top of each other.
  • the mattress body is designed to assume also an active configuration in which said inflatable elements are in an inflated condition.
  • the form of the mattress body which, as mentioned, is formed overall by a plurality of tubular elements arranged adjacent in sequence, favours unfolding from the stacked condition into the inflated condition where they are extended and unfolded.
  • Each inflatable element has an elongated, preferably tubular, form and therefore the internal channel-shaped chamber, when the inflatable element is substantially inflated, has a form corresponding to the internal hollow zone of a tubular element.
  • the tubular elements are in fact narrow and long separate bodies which are joined together in sequence side-by-side. More particularly, they consist of elements which are straight in the inflated condition, namely have a straight and/or rectilinear - and not curved - form. In this way, the tubular elements may easily pass from a compact stacked condition into an extended or unfolded condition in which the inflatable elements are fully expanded so as to obtain the flat-shaped mattress body, with an inflated panel-like configuration.
  • each inflatable element has mutual connection zones and separation zones.
  • the mutual connection zones are configured to maintain a mutual connection between the adjacent inflatable elements, while the separation zones are configured to maintain a separation between adjacent inflatable elements.
  • the separation zones defines a plurality of through-channels passing between adjacent inflatable elements.
  • the protection device also includes a covering sleeve or simple cover, which defines an internal zone where the mattress body is housed.
  • the set of inflatable elements is therefore lined with at least one cover, or covering sleeve, configured to provide the airbag with greater dimensional stability and therefore resistance to high pressures.
  • it may provide greater abrasion resistance and therefore, for example, may be made of a material such as a synthetic fabric, for example Cordura, but may also be made of a material with fireproof/flame-proof properties so as to ensure greater fire resistance.
  • it may be formed by a pair of sheets arranged opposite each other and joined together along a respective perimeter or may be a single body.
  • the covering sleeve therefore defines an internal zone or region where the mattress body including the plurality of inflatable elements is arranged.
  • the device furthermore includes one or more tie elements connected to the covering sleeve and each slidably and/or freely inserted inside a respective through-channel.
  • each tie element is not fixed directly to the inflatable elements, but surrounds the outer sleeve so as to help provide the flat form of the mattress body and give the entire device a greater dimensional stability and consequently resistance to high pressures. Owing to the sliding and free insertion inside the respective through-channel, the tie element may adjust the form of the protection device, without however directly acting on the inflatable elements so as to avoid excessive tensioning of the inflatable elements.
  • the mutual connection zones are adherence areas.
  • the inflatable elements therefore have side walls adhering in pairs and two opposite walls which, once the inflatable elements are joined together, form opposite external surfaces of the mattress body, namely a surface or wall exposed to an impact or to the cold and a rear wall facing the user.
  • the two opposite surfaces are substantially flat in the inflated condition.
  • the tie elements protrude from the opposite surfaces and are connected to the cover.
  • the inflatable element may be easily combined with other protection devices or elements, for example rigid plate-type protection bodies, separate from the inflatable element and having a form matching that of the inflatable element in the inflated condition, or inserted inside the pocket of the wearable article.
  • other protection devices or elements for example rigid plate-type protection bodies, separate from the inflatable element and having a form matching that of the inflatable element in the inflated condition, or inserted inside the pocket of the wearable article.
  • a further advantage consists in the fact that the tie elements and the partially adhering walls of the inflatable elements ensure a limited expansion of the inflatable element in an inflated condition so as to obtain a smaller overall size, and in particular a limited thickness, while at the same time ensuring adequate protection for a user.
  • a wearable article such as a garment, a jacket, a suit or other article of clothing.
  • This smaller size moreover ensures, in the event of accidental inflation of the inflatable element, less inconvenience and risk for a user while driving a vehicle. In other words, a limited expansion of the inflatable element does not adversely affect control of a vehicle by the user and therefore does not pose the risk of an accident.
  • Another advantage consists in the fact that, by controlling the form of the inflatable element. it is possible to control (and in particular limit) also the amount of gas needed for inflation of the inflatable element.
  • the inflatable mattress body is therefore a flexible body which, in the inflated condition, maintains this condition at least for a given time period.
  • it consists of a body which is impermeable to an inflation gas.
  • a breather valve is provided for deflation of the mattress body.
  • a body made of a pressure-resistant material which is able to ensure the gas-tightness for at least a certain period of time, may be used as the material for the mattress body.
  • Said material may be, for example, PU (polyurethane), EVA (ethylene vinyl acetate) or TPE (thermoplastic elastomer).
  • PU polyurethane
  • EVA ethylene vinyl acetate
  • TPE thermoplastic elastomer
  • These membranes may also be impregnated with non-extensible fine meshes in order to ensure greater tightness of the inflatable elements (in terms of expansion resistance).
  • a wall of an inflatable element of the plurality of inflatable elements is fixed so as to adhere only locally to a wall of an adjacent inflatable element of the plurality of inflatable elements, so as to define a mutual connection zone between two adjacent inflatable elements.
  • each inflatable element, or part of them includes at least two walls which are joined together along a perimeter so as to define a perimetral joining edge.
  • said adherence zone between two adjacent inflatable elements alternates with a perimetral joining edge of the two inflatable element walls.
  • the inflatable element is in fact a double-leaf body, namely similar to a body with two flat sheets joined together along the perimeter so as form a long and narrow body. It can be understood that the prechosen geometrical form of an inflatable element with a double leaf joined together along the perimetral edge favours the compression of one wall against another one in the deflated condition like a concertina and at the same time the opening into the inflated condition again in the manner of a concertina.
  • the protection device preferably also includes one or more gas sources connected to the inflatable mattress body so as to inflate the mattress body between the deflated condition and the inflated condition.
  • the gas source may be housed inside the internal channel-like chamber of an inflatable element.
  • the gas source may be a pressurised gas generator or a manual inflation device which can be activated by a user, such as an air pump.
  • the inflatable elements may each have independent access to one or more gas sources.
  • the adjacent inflatable elements are in fluid communication with each other for common inflation.
  • the mattress body includes through-holes or fluid communication holes in the adhering walls of two said adjacent inflatable elements so as to provide the fluid communication.
  • an inflation device comprising a fluid generator may be arranged outside the inflatable elements and connected there in fluid communication by means of a suitable connection.
  • the protection device can be housed in a receiving area of the garment or in a garment portion.
  • Said portion is understood as being a garment portion which covers a part of the body, such as the torso (neck region, chest region, shoulder joint region, back and arms).
  • the garment portion includes said layer and is made using a predefined textile technology able to provide the garment with given properties, such as breathability, or with ventilation openings.
  • wearable article is understood as meaning any article or portion thereof which may be worn by a user, such as an article of clothing, a garment or other wearable accessory.
  • the wearable article includes a protection device such as that described above and at least one layer defining a zone for receiving the body of a user, i.e. intended to receive the body of a user for a protective function, whether it be protection from impacts or protection from the cold or the like.
  • the protection device is associated with said layer, on one side, which may be identified as the inner layer of said layer, facing said receiving area.
  • the layer of the wearable article also has a breathability property or has at least one ventilation opening.
  • the receiving area includes a first part and a second part open towards the first part, and the breathability property or ventilation opening is associated at least with said second part of the receiving area so as to allow ventilation at least in said second part.
  • the mattress body performs its protection function in the inflated condition, while ventilation and breathability may be ensured when the mattress body is in the deflated condition.
  • the second part of the receiving area is configured to receive the mattress body in the extended and inflated condition, while it remains free to allow breathability when the mattress body is in the rest configuration.
  • the mattress body occupies both said first part of the receiving area and said second part of the receiving area and preferably the whole of the second part of the receiving area.
  • the mattress body occupies only the first part of the receiving area. Consequently, once housed inside the garment and the mattress body is in the deflated condition, the second part of the receiving area, which is normally devoid of mattress body, is able to allow the breathability and ventilation of the garment.
  • the reference number 100 indicates a wearable article, in the present case a waistcoat, including a personal protection device 10 according to the present disclosure in accordance with a respective embodiment of the present disclosure.
  • a portion of the wearable article 100 for example the chest portion, or back portion, according to the present disclosure includes at least one layer 11 defining an area for receiving the body of a user.
  • the layer is a layer of the waistcoat or a lining of the waistcoat.
  • the layer 11 is to be understood as being a layer of the waistcoat, in general, made of fabric or other material. Preferably, as will be explained more clearly below, at least part of the layer 11 allows breathability and the entry of air inside the wearable article 100.
  • the waistcoat or similar wearable article 100 includes an area - indicated by means of broken lines and the reference number 12 - which is intended to receive the body of a user for a protection function, whether it be protection from impacts, protection from the cold, or any other kind of protection.
  • the receiving area 12 is, in the embodiment shown, an area intended to receive the torso of a user.
  • the layer 11 also has, as mentioned, a breathability property or has at least one ventilation opening 15.
  • the protection device 10 is associated with said layer 11, on an inner side of said layer towards the receiving area, as shown in Figures 7 and 8 .
  • the personal protection device 10 includes a mattress body 16, including a plurality of inflatable elements 18, arranged adjacent in sequence, wherein each inflatable element has the form of a long and narrow envelope, preferably tubular shaped, i.e. in the form of a closed tube, so as to each define an internal chamber 19 shaped like a channel.
  • the inflatable elements 18 and the respective internal chambers 19 are preferably in fluid communication by means of through-holes so as to form a single inflation chamber for said inflatable elements 18.
  • the inflatable elements 18 which form the mattress body 16 are identical to each other in terms of shape and size, namely they all have the same form and the same dimensions.
  • the inflatable elements 19 may have a different shape and/or size, for example at least one of the inflatable elements 18 may have dimensions greater than or smaller than other inflatable elements 18 of the mattress body 16, or may be shaped differently from other inflatable elements 18 of the mattress body 16.
  • the inflatable elements 18 may be organized or grouped together in groups of inflatable elements, wherein each group of inflatable elements may comprise, or group together, inflatable elements 18 with the same shape and/or size.

  • a first group of inflatable elements with a first shape and/or size may be associated with or arranged alongside a second group of inflatable elements, wherein the second group of inflatable elements comprises inflatable elements with a second shape and/or size, wherein preferably the second shape and/or size is different from the first shape and/or size.
  • each inflatable element 18 has at last one mutual connection zone 20 and at least one separation zone 21.
  • the mutual connection zones are configured to maintain a mutual connection, namely one where they are joined together and preferably totally adherent, between the adjacent inflatable elements 18, while the separation zones 21 are configured to maintain a separation between adjacent inflatable elements 18. Consequently, the separation zones 21 define a plurality of through-channels 28 passing between adjacent inflatable elements 18.
  • the adjacent inflatable elements 18 have mutual connection zones 20 where the adjacent inflatable elements 18 are connected for example by means of gluing together, stitching or similar joining systems, and separation zones 21, where the adjacent inflatable elements 18 are kept separate and/or disconnected.

  • the device furthermore includes one or more tie elements 52 connected to the cover 50 or covering sleeve and each slidably and/or freely inserted inside a respective through-channel 28 between the inflatable elements 18.
  • the one or more tie elements 52 surround(s) the cover 50 and is free to slide with respect to the inflatable elements 18 so as to allow form control (since it is fixed to the cover 50) but without creating a tension on the inflatable elements 18.
  • each of the inflatable elements 18 has ta least one side wall 18a, 18b partially adhering to an adjacent side wall 18a, 18b of an adjacent inflatable element and two opposite walls 18c, 18d which, once the sequence of inflatable elements 18 has been defined, form opposite external surfaces, namely a surface or wall exposed to an impact, or to the cold, and a rear wall facing the user.
