Definitions

  • the present disclosure relates generally to the sector of providing protection by means of an airbag, so as to protect a user from impacts due to falling or sliding, when travelling on a means of transport, such as a vehicle, preferably a two-wheeled vehicle, or any other means of transport, such as a horse or other animal, sports equipment, such as a pair of skis or a bobsleigh, or similar means of transport. More particularly, the present disclosure relates to a wearable protection device including at least one inflatable element for protecting a user in the event of falls and/or impacts of various types.
  • a wearable protection device including an inflatable element which has a form such as to cover the torso of a user, both in a chest zone and in a back zone.
  • the inflatable element is inflated in the event of an impact by an inflation device which is placed in fluid communication with the said inflatable element.
  • said inflation device includes a fluid source, such as a compressed gas cylinder, which is generally referred to as a gas generator.
  • the gas generator is generally associated with a back portion of the wearable protection device or of a garment which incorporates said wearable protection device.
  • the back may be provided with a back protector which may support the gas generator.
  • a plate-shaped support body which, when placed on the back, does not hinder the movements of the user may also be used instead of the back protector.
  • the wearable protection device includes a rigid protector or other support device for the back, which, in addition to the wearable protection function, performs a support function for the gas generator.
  • a portion of the inflatable element connected to the gas generator is inserted inside the back protector or in the support device.
  • the position of the gas generator in the back area of a user makes the wearable protection device safer, preventing the gas generator from being able to interfere with the vital organs situated in the front part of the user, in the event of a fall.
  • the present disclosure is based on the recognition by the inventor of the present disclosure that a wearable protection device such as that made available hitherto by the prior art, while being advantageous from many points of view, has the drawback that it cannot be easily adapted in the case where the gas generator must be replaced after a first inflation of the inflatable element.
  • the gas generator is located inside the back protector, the latter must be disassembled in order to allow access to the gas generator. Disassembly for access to the gas generator may result in the risk of displacing also the inflatable element from its seat or, in any case, may require expert action on the wearable garment in order to change the gas generator and reassemble the entire safety protection device.
  • the starting point of the present disclosure is the technical problem of providing a wearable protection device which is able to satisfy the aforementioned need with reference to the prior art for easy access to the gas generator, while maintaining compact dimensions of the entire wearable protection device and/or achieving further advantages and characteristic features.
  • the wearable protection device comprises at least one inflatable element, a gas generator and a coupling device for coupling the gas generator to the inflatable element, the coupling device including a coupling element associated with the gas generator and a coupling counter-element associated with the inflatable element.
  • support device is generally understood as meaning a body or assembly, which may be plate-shaped and/or closed in the manner of a box/casing able to support the components of the device and in particular the gas generator.
  • the support device may be particularly suitable for arrangement on the back of a user and/or also have the configuration of a back protector.
  • the inflatable element includes a primary portion of the inflatable element and a secondary portion of the inflatable element.
  • the secondary portion of the inflatable element is connected as one piece with the primary portion and is provided with said coupling counter-element, wherein the support device is at least partially superimposed on the primary portion of the inflatable element so as to form a multilayer structure therewith, and said secondary portion protrudes with respect to said support device and is in the folded or overturned condition, or a folding or overturning condition, said folding or overturning condition corresponding to a housing condition of said coupling counter-element in said receiving seat of the support device.
  • the folded or overturned condition is understood as being a condition in which the secondary portion is folded or overturned onto itself, namely protrudes from the primary portion and is folded back from the primary portion.
  • the inflatable element may be connected with the gas generator and allows inflation of the inflatable element.
  • the first advantage consists in the fact that a primary portion consisting of the inflatable element with a protective function may be placed underneath the wearable protection device, on the user side, and is configured so that the coupling counter-element protrudes with respect to the support device, by means of the secondary portion.
  • the secondary portion being in the folded or overturned condition, may allow the coupling counter-element to be inserted inside the receiving seat with significant control of the overall dimensions.
  • the support device may be superimposed on the inflatable element and allow the wearable protection device to offer double protection both on the side of the support device and on the side of the inflatable element and at the same time provide a minimal small-size connection between the gas generator and the inflatable element.
  • the overturning or folding condition is a condition in which the secondary portion is folded 180° about itself and/or with respect to the primary portion, namely it consists of a full fold which results in an overlapping arrangement of two secondary portion parts and/or at least one part of the secondary portion with respect to the primary portion.
  • the secondary portion may be arranged substantially squashed and flat without substantially additional volume in the deflated condition.
  • the support device has a through-opening configured to allow access to said receiving seat and is designed to receive a secondary portion part of the inflatable element which carries the coupling counter-element or also only the coupling counter-element so as to allow stable coupling between the inflatable element and the gas generator arranged inside the receiving seat.
  • the wearable protection device has a user-side area, namely an area or portion intended to face the body of a user.
  • a user-side area namely an area or portion intended to face the body of a user.
  • the wearable protection device when the wearable protection device is worn, it defines an area for receiving the user's body.
  • the primary portion of the inflatable element is arranged underneath the support device, namely on the side of said user-side area with respect to the support device. Consequently, as a result of the aforementioned layout of the aforementioned parts, the secondary portion protrudes from the support device and is folded outwards, preferably through 180°, towards the support device so as to reach the receiving seat.
  • said through-opening is arranged on the side of said user-side area and is therefore preferably hidden from view.
  • the secondary portion of the inflatable element is folded so as to be arranged between the support device and the primary portion of the support element and is therefore only marginally visible.
  • the connection between the inflatable element and the gas generator may therefore be not only compact in size, but also hidden from view.
  • the secondary portion of the inflatable element is a peripheral appendage which does not have a wearable protection function but only serves to provide the connection between the primary portion and the gas generator receiving seat.
  • the wearable protection device is configured and organized so that the coupling counter-element is permanently received inside the receiving seat and the gas generator is connected if necessary by means of the respective coupling element to the coupling counter-element.
  • the connection may be of the removable type, so that, once inflation of the inflatable element is performed, it is necessary merely to remove and replace the gas generator.
  • the receiving seat may be configured to include elastic coupling elements, for example of the clip type, so as to allow a stable form-fit and at the same time rapid removal of the gas generator in/from the coupling seat.
  • the support device comprises a bottom or base structure which includes said seat for receiving the gas generator, and a wearable protective cover for the gas generator, said wearable protective cover being removable from said bottom or base structure.
  • the support device may be made of a soft material or a material which is not necessarily rigid.
  • the bottom or base structure is arranged on the user side and the wearable protection cover faces the opposite side, namely an outer side.
  • the support device is configured to support also further functional elements for the wearable protection device, such as a control unit and sensors for detecting a danger situation.
  • the wearable protection device may also have a back protector or generally wearable protection function for the back.
  • the primary portion of the inflatable element is a portion providing wearable protection for the back of a user, and the support device is superimposed on said primary portion on the back so as to have minimum dimensions and a minimum impact for a user.
  • the inflatable element therefore extends over the back as far as a neck zone.
  • the secondary portion is a peripheral portion with respect to the primary portion and preferably is a portion which projects in the manner of an appendage or an extension extending in a neck zone of the inflatable element, and is in a condition folded or bent back towards the back.
  • the position of the support device on the back allows or does not hinder flexing and twisting movements of the user's back.
  • the inflatable element overall is a structure which protects the main portions of a user's torso and comprises inflatable element portions on the back and chest, leaving free a central cavity where the user's head is inserted.
  • the inflatable element is cut to size to define said cavity and therefore there are normally inflatable element waste portions which are not used.
  • the secondary portion is formed preferably precisely in said regions which would be waste regions, safeguarding therefore inflatable element portions which otherwise would be eliminated and without therefore using additional portions of the inflatable element.
  • each embodiment may have one or more of the advantages listed above; in any case it is nevertheless not necessary that each embodiment should have simultaneously all the advantages listed.
  • Weightable protection device is understood as meaning a device which may be worn, namely placed on a user's body with a protective function, or which can be associated with or is designed to be associated with a garment or an undergarment, such as a motorcycling suit, a jacket, a vest or a pair of trousers. Since it is a device which can be preferably worn, in the context of the present disclosure reference will be made for greater clarity to parts of the body which said wearable protection device is intended to protect, and in general to spatial references such as above, below, inner and outer and similar references which are to be understood in a nonlimiting manner as though the device were being worn.
  • the wearable protection device 10 comprises at least one inflatable element 12, a gas generator 14 and a coupling device 16 for coupling the gas generator 14 to the inflatable element 12 ( Figure 5 ).
  • the coupling device 16 includes a coupling element 18 associated with the gas generator 14 and a coupling counter-element 20 associated with the inflatable element 12. It should be noted that in Figure 4 the coupling counter-element 20 is detached from the inflatable element since it consist of an assembly stage. However, once the entire wearable protection device 10 is assembled, the coupling counter-element 20 is associated preferably permanently with the inflatable element 12. The coupling counter-element 20 may be preferably a bush-like body associated with the inflatable element 12.
  • the gas generator 14 may be a structure which is for example canister-shaped, namely has a substantially cylindrical structure.
  • the gas generator 14 is to be understood as being a source of inflation fluid and may be a gas generator of the pyrotechnic or hybrid type or other types known according to the state of the art.
  • the wearable protection device 10 further comprises a support device 30 defining a receiving seat 32 for receiving the gas generator 14 and the coupling device 16 and allowing coupling together of the inflatable element 12 and the gas generator 14 inside said receiving seat 32.
  • the inflatable element 12 includes a primary portion 22 of the inflatable element 12 and a secondary portion 24 of the inflatable element 12 connected as one piece with the primary portion 22.
  • the secondary portion 24 is provided with, or supports, said coupling counter-element 20.
  • the support device 30 is at least partially superimposed on the primary portion 22 of the inflatable element 12 so as to form a multilayer structure.
  • the secondary portion 24 protrudes with respect to said support portion 30.
  • the secondary portion 24 of the inflatable element 12 is in the folded or overturned condition, or folding or overturning condition, towards the support device 30.
  • the folding or overturning condition corresponds to a housing condition of the coupling counter-element 20 in said receiving seat 32.
  • the coupling counter-element 20 is in said receiving seat 32 of the support device 30 and already connected to the secondary portion 24 of the inflatable element 12.
  • the inflatable element 12 may be connected with the gas generator 14 and allows inflation of the inflatable element 12.
  • the secondary portion 24 supports the coupling counter-element 20 and may be folded towards the support device 30 to allow housing of the coupling counter-element 20 inside the receiving seat 32 with consequent significant control of the overall dimensions.
  • the secondary portion 24 may also be partly housed inside the receiving seat 32 or may be arranged outside such that the only the coupling counter-element 20 is inside the receiving seat 32.
  • said part of the secondary portion is arranged so as to project or only face into the receiving seat 32 so that the coupling counter-element 20 may be then fixed inside the receiving seat 32.
  • the support device 30 may be superimposed on the primary portion 22 of the inflatable element 12 and double protection provided both by the support device and by the inflatable element 12 while ensuring a minimum small-size connection with the inflatable element 12.
  • the secondary portion 24 of the inflatable element may not have any protective function and act only as a connecting element between the primary portion and the gas generator 14. It is pointed out that the inflatable element 12 may be cut to size so that the secondary portion 24 may be, or correspond to, a cut-out or waste portion of the inflatable element 12, for example, as explained below, in the neck region.
  • the overturning or folding condition is a condition in which the secondary portion 24 is folded 180° about itself and/or with respect to the primary portion, namely it consists of a full fold which results in the overlapping arrangement of a secondary portion 24 with respect to the primary portion 22.
  • the secondary portion 24 is a portion without a protective function which acts only as a connection and may be obtained from a perimetral zone of the inflatable element (which otherwise would be cut off) and folded backwards 180° preferably above, or below, the primary portion, so as to reach the receiving seat.
  • the secondary portion 24 may be arranged substantially squashed and flat onto the primary portion 22 without substantially additional volume in the deflated condition.
  • the inflatable element 12 is intended to protect at least partially a torso area of the user. More precisely, in the embodiment shown, the inflatable element 12 includes a first part 121 intended to be placed in the neck region, chest parts 122, 123 each intended to be placed along a right-hand and a left-hand region of the chest, respectively, and a spinal or back portion 126 intended to be placed along a back region which is centred on the backbone of the user.
  • the aforementioned primary portion 22 of the inflatable element 12 may be understood as being part of the spinal portion 126 of the embodiment shown, underlying the support device 30.
  • the parts 121 122 123, 126 of the inflatable element 12 are pneumatically connected together to form a single inflatable chamber.
  • the support device covers an outer side, namely a side opposite to the user, part of the spinal portion 126 and, together with the spinal portion 126 of the inflatable element 12, is intended to protect the backbone of the user. It may be understood how the support device 30 may also have other forms, and the form shown is not to be regarded as limiting for the purposes of the present disclosure.
  • the wearable protection device 10 has a user-side area 38, namely an area or portion intended to face the user's body when the wearable protection device 10 is worn by said user, and the inflatable element portion is arranged on said user-side area 38 with respect to the support device 30.
  • the secondary portion 24 protrudes from the support device 30 and is in a condition folded backwards or on the outside, preferably through 180°, towards the support device 30 so as to create said connection with the receiving seat 32.
  • the support device has a through-opening 40, which is preferably arranged in said user-side area 38, and wherein said through-opening 40 is an opening configured to allow access to said receiving seat 32 and is designed to receive the coupling counter-element 20 associated with the inflatable element 12 so as to ensure a stable connection between the inflatable element 12 and the gas generator 14 arranged in said receiving seat 32.
  • the wearable protection device 10 when worn, it defines an area for receiving the user's body.
  • the support device 30 has a side 38 facing the user's body, and this through-opening 40 is arranged on this side 38 facing the user's body so that the secondary portion 24 of the inflatable element 12 may be inserted between the support device 30 and the primary portion 12 on side which is hidden from view.
  • the secondary portion 24 of the inflatable element is a peripheral appendage which does not have a protective function but only serves to provide the connection between the primary portion 22 and the receiving seat 32 for housing the gas generator 24.
  • the secondary portion 24 is an appendage which extends into the cavity which is intended to receive the user's neck and is in a condition folded backwards, namely outwards, so as to be inserted underneath the support device 30 and reach the through-slot 40.
  • This zone is usually a waste zone and therefore the appendage is a part of the inflatable element which does not require additional production costs, since it merely involves a cut with a different design.
  • the coupling counter-element 20 may be permanently fixed to the end of the secondary portion 24 and therefore the coupling counter-element 20 may remain permanently seated inside the receiving seat 12, and the gas generator 14 connected by means of the respective coupling element 18 to the coupling counter-element 20.
  • the connection may be of a mechanical connection of the removable type, so that, once inflation of the inflatable element 12 is performed, it is required to remove and replace only the gas generator 14.
  • the receiving seat 32 preferably includes elastic coupling elements, for example of the clip type, so as to allow a stable form-fit and also rapid removal of the gas generator 14 in/from the coupling seat 32.
  • the coupling device 16 may be of any type according to the prior art.
  • the support device 30 comprises a bottom or base structure 50 which includes said receiving seat 32 for the gas generator 14, and a protective cover 52 for protecting the gas generator 14.
  • the protective cover 52 is removably associated with said bottom or base structure by means of a mechanical connection of the known type.
  • the bottom or base structure 50 is arranged on the user side 38 and the protective cover 52 faces the opposite side, namely an outer side.
  • the support device 30 is configured to support also further functional elements for the wearable protection device, such as a control unit and sensors for detecting a danger situation. These further elements are generally indicated by the reference number 53 in the figures.
  • the primary portion of the inflatable element may perform its function and be connected to the gas generator while occupying a minimum volume, owing to the secondary portion which protrudes from the volume of the support device and which, once folded back towards the support device 30, defines a kind of double layer because of the fold.
  • This double layer of the secondary portion advantageously and preferably has an overall thickness which is much less than the thickness of the support device 30.
  • the inflatable element 12 may be a single bag and made using the technology described in the patent application PCT/IB2009/055512 and in the patent application PCT/IT2009/000547 .
