[0001] 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.
[0002] In the sector relating to the protection of user it is in fact known to use 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.
[0003] 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. Generally,
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.
[0004] The arrangement of the gas generator on the back is facilitated by the fact that
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.
[0005] Basically, 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. In order to connect the gas generator to
the inflatable element, a portion of the inflatable element connected to the gas generator
is inserted inside the back protector or in the support device.
[0006] It has also been proposed inserting the gas generator in this portion of the inflatable
element and including the combined assembly of the gas generator and the inflatable
element in the back protector.
[0007] It should be pointed out that 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.
[0008] 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.
[0009] In fact, if 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.
[0010] It has therefore been proposed positioning the gas generator outside of the back
protector on an external support which may be positioned on a surface of the back
protector so that the gas generator is easily accessible without disassembly of the
back protector. However, this solution results in an increase in the overall dimensions
of the wearable protection device since a part of the wearable protection device is
located outside the back protector.
[0011] Further solutions involve arranging the gas generator on one side of the back protector
on the outside thereof, but this results in the wearable protection device being generally
less comfortable.
[0012] 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.
[0013] This is obtained by means of a wearable protection device, a method for assembling
an inflation device of the wearable protection device, and a garment according to
the respective independent claims. Secondary characteristic features forming the subject
of the present disclosure are defined in the corresponding dependent claims.
[0014] The wearable protection device, according to the present disclosure, 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.
[0015] The expression "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.
[0016] According to one aspect of the present disclosure, 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.
[0017] Preferably, 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.
[0018] In this condition, the inflatable element may be connected with the gas generator
and allows inflation of the inflatable element.
[0019] This solution offers numerous advantages. 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. In this way,
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.
[0020] Preferably, 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.
[0021] In this condition the secondary portion may be arranged substantially squashed and
flat without substantially additional volume in the deflated condition.
[0022] Preferably, 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.
[0023] Preferably, the wearable protection device has a user-side area, namely an area or
portion intended to face the body of a user. In other words, when the wearable protection
device is worn, it defines an area for receiving the user's body. In this condition,
when the wearable protection device is worn by said user, 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.
[0024] Preferably, said through-opening is arranged on the side of said user-side area and
is therefore preferably hidden from view. In this condition, 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.
In other words, the connection between the inflatable element and the gas generator
may therefore be not only compact in size, but also hidden from view. Preferably,
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.
[0025] Even more preferably, 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.
[0026] Preferably, 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.
[0027] It is to be understood that the support device may be made of a soft material or
a material which is not necessarily rigid.
[0028] Preferably, the bottom or base structure is arranged on the user side and the wearable
protection cover faces the opposite side, namely an outer side. In this way, a user
may access the gas generator from the outside. 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.
[0029] As mentioned above, the wearable protection device may also have a back protector
or generally wearable protection function for the back. More generally, preferably,
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.
[0030] The position of the support device on the back allows or does not hinder flexing
and twisting movements of the user's back.
[0031] Preferably, 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. In these conditions,
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.
[0032] Further advantages, characteristic features and modes of use forming the subject
of the present disclosure will become clear from the following detailed description
of a number of preferred examples of embodiment thereof, provided by way of a nonlimiting
example.
[0033] It is nevertheless evident that 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.
[0034] Reference will be made to the figures of the attached drawings in which:
- Figure 1 shows a view, from the rear, of a wearable protection device according to
an embodiment of the present disclosure;

- With reference to the attached figures, the reference number 10 indicates a wearable
protection device according to the present disclosure.
[0035] "Wearable 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.
[0036] The wearable protection device 10 according to the present disclosure 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).
[0037] 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.
[0038] 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.
[0039] According to one aspect of the present disclosure, 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.
[0040] The secondary portion 24 is provided with, or supports, said coupling counter-element
20.
[0041] 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.
[0042] Furthermore, advantageously, 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. In particular,
in said folding or overturning condition, 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.
[0043] In this condition, the inflatable element 12 may be connected with the gas generator
14 and allows inflation of the inflatable element 12. In other words 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. In fact, 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.
[0044] In this way 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.
[0045] 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.
[0046] Furthermore, preferably, 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. In other words,
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.
[0047] In this condition the secondary portion 24 may be arranged substantially squashed
and flat onto the primary portion 22 without substantially additional volume in the
deflated condition.
[0048] In the embodiment shown, 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.
[0049] The parts 121 122 123, 126 of the inflatable element 12 are pneumatically connected
together to form a single inflatable chamber. Preferably, in the embodiment shown
in the drawings, 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.
[0050] As a result, preferably, as regards the layout of the parts described above, 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.
[0051] Preferably, from a constructional point of view, 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. In other words, when the wearable
protection device 10 is worn, it defines an area for receiving the user's body. In
this condition, 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.
[0052] Preferably, as mentioned, 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.
[0053] Even more preferably, in the embodiment shown, 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.
[0054] It may be stated that, once it faces the end part of the secondary portion 24 inside
the through-slot 40, 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.
[0055] Preferably, 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.
[0056] Preferably, from a constructional point of view, 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.
[0057] It may be pointed out that, owing to the present disclosure, 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.
[0058] With regard to the inflatable element 12, it is pointed out that it 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. This inflatable element 12 has a small thickness also in the inflated condition
and therefore the aforementioned double layer does not occupy extra space even in
the inflated condition.
[0059] The wearable protection device 10 according to the present disclosure may be worn
on its own as a separate garment, optionally lined with a fabric aesthetically pleasing
for the user, or made of a comfortable and practical fabric, or may be incorporated
in suitable pockets inside a garment, such as a motorcyclist's suit or jacket.
[0060] With reference to Figure 6, the present disclosure in fact also relates to a protective
garment 100 comprising a wearable protection device 10 such as that described above
and including an inflatable element 12 and the support device 30. In this embodiment,
the parts which perform the same function have the same reference number.
[0061] In particular, the support device 30 may be arranged on top of an outer layer 101
and the inflatable element 12 may be arranged below the outer layer 101 of the garment,
so that it is hidden from view. The respective secondary portion 24 may be inserted
inside a seat passing through the outer layer 101 and arranged below the support device
30 so as to reach the seat 32.
[0062] It is however possible for the inflatable element 12 to be shaped directly as a garment
and for the inflatable element to be provided with laces, hooks, ribbons or other
means known to the person skilled in the art, in order to ensure suitable wearability.
In other words, it is to be understood that the wearable protection device 10 according
to the present disclosure may be worn on its own as a separate garment, optionally
lined with a fabric aesthetically pleasing for the user, or made of a comfortable
and practical fabric, or may be incorporated in suitable pockets inside a garment,
such as a motorcyclist's suit or jacket.
[0063] Even if the wearable protection device 10 were shaped as a garment, the secondary
portion 24 may have a minimum visual impact for the user from the outside or may be
covered by a cover.
[0064] Alternatively again, owing to the minimum dimensions, the wearable protection device
10 may be included inside a lining of a garment in a removable manner. In particular
a user may fix and connect, as required, an inflatable element 12 to the respective
garment 100 and then wear the garment 100 already equipped with said wearable protection
device 10. As a result, a user may use the same wearable protection device 10 with
different garments 100 and change the wearable protection device 10 depending on the
garment 100 chosen and the activity to be performed.
[0065] With regard to inflation, in order to perform inflation of the inflatable element
12, in the event of a fall and/or sliding and/or sudden impact involving a user or
a vehicle being ridden/driven, the wearable protection device 10 is adapted to cooperate
with special activation means (not shown) which are operationally connected to the
pressurised gas generator 14 and associated with the components 53 indicated above.
Opening of the shut-off valve of the gas generator 14 is preferably controlled by
the control and management unit depending on detection of the user state; for example
said control unit (which forms part of said activation means 53) may implement a system
for predicting the fall which allows early identification of the fall event and a
reliable prediction of this by accelerometer sensor means fixed to the vehicle/ski
(or rider/skier) and a unit for processing the signals produced by the said sensors.
[0066] Alternatively, the device according to the present disclosure may also be applied
using an activation cable connected to a vehicle ridden/driven by a user, which cable
activates inflation of the inflatable element following the movement of the user away
from the vehicle, for example following a fall or a sudden impact.
[0067] In any case the aforementioned activation and inflation means 53 may be integrated
in the wearable protection device according to the present invention or located on
the outside thereof.
[0068] It should also be noted that the activation modes, although being an aspect of particular
importance for effective operation of the device, will not be further described in
greater detail since they are methods which are essentially already known to a person
skilled in the art of protection of a person from sudden impacts. The subject of the
present disclosure has been described hitherto with reference to preferred embodiments.
