[0001] The present disclosure relates in general to a personal protection device for protection
of a user, wherein the device is preferably of the wearable type and/or type which
can be associated with a wearable article, such as a garment.
[0002] In detail, the present disclosure relates to a protection device which may be a so-called
"stand-alone" device or part of a wearable article, such as a garment or other article
of clothing. The protection device includes in particular an inflatable body which,
in the inflated condition, is configured to protect from impacts and/or falls a motorcycle
rider or passenger or similar user, during a sporting activity and/or working activity
and/or any other activity.
[0003] Traditionally, a known protection device includes an inflatable element designed
to assume a deflated rest condition and an inflated active condition. Generally, the
inflatable element includes a knitted body, namely a body made by means of knitting
process. Said knitted body is a closed structure defining an inner region or area
or chamber. The inflatable element also includes sealing walls which 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 a second sheet, or second wall, which are fixed
together along respective perimetral edges. Said first and second sheets made of fluid-tight
material cover and line the knitted body on an outer side or outer surface.
[0004] These known devices, while being advantageous from many points of view, are characterized
by the main disadvantage that they do not allow efficient ventilation, when they are
arranged on a wearable article, such as a jacket or suit, between an outer surface
of the wearable article, or garment, and an inner surface thereof, directed, during
use, towards the body of a user. In particular, in these known devices, the inflatable
element, being at least partly made of fluid-tight material, and arranged so as to
occupy entirely a given pocket, or region, of the wearable article, prevents the exchange
of air between the aforementioned inner and outer surfaces of the wearable article.
[0005] In order to solve this problem, wearable protection devices which comprise an inflatable
body which, in an inactive condition, or deflated condition, is folded onto itself,
occupying therefore a limited portion of a pocket, or region, of a garment, have been
developed. In this way, when the inflatable body is in the inactive condition, the
exchange of air between the outer surface and the inner surface of the wearable article
comprising the protection device is allowed, at least in a portion thereof which is
not occupied by the inflatable body. In these devices, the inflatable body is configured
to expand, for example along an expansion or inflation direction, when it is activated,
or inflated, thus occupying a space, or region, greater than that in the inflated
condition. In other words, the transition from the inactive condition to the active
condition corresponds to unrolling or unfolding of the inflatable body which, in the
active condition, is configured to occupy a region, or space, which previously was
not occupied in the inactive condition or deflated condition.
[0006] The present disclosure is based on the recognition of the fact that the unrolling
or unfolding of the inflatable body is, however, particularly critical in the known
devices.
[0007] In particular, the pocket, or insert, of the wearable article in which the inflatable
body is inserted makes unfolding of the latter difficult and risks compromising effective
protection for a user.
[0008] The risk when using the known protection devices in which the inflatable element
is configured to extend, or expand, is that said extension is not performed properly,
namely that the inflatable body extends or unfolds only partly, or in a non-uniform
manner, leaving unprotected zones of a user's body which the inflatable body is supposed
to be configured to protect, thus negatively affecting the general effectiveness of
the protection device. In other words the expansion may occur in an incorrect manner.
[0009] The present disclosure proposes providing a personal protection device which is able
to overcome the drawbacks mentioned above with reference to the prior art and/or achieve
further advantages.
[0010] This is obtained by means of a personal protection device, a wearable article comprising
such a personal protection device, and a method for protection of a user by means
of a personal protection device as defined in the respective independent claims. Secondary
characteristics and particular embodiments of the subject of the present invention
are defined in the corresponding dependent claims.
[0011] In particular, the personal protection device according to the present disclosure
comprises at least one inflatable element configured to assume a first rest configuration,
or deflated configuration, and a second active configuration, or inflated configuration.
During the transition from the first rest configuration, or deflated configuration,
to the second active configuration, or inflated configuration, the inflatable element
increases the useful space for protection. Advantageously, therefore, in the rest
configuration, the inflatable element may occupy in the rest condition, or deflated
condition, a limited portion of a wearable article, allowing therefore effective ventilation
and at the same time ensuring useful protection in the event of danger, being able
to expand, or stretch, so as to protect an area of a user's body which is broader
or greater than the area occupied in the rest condition.
[0012] Preferably, in the first configuration, the inflatable element is in a folded or
packed configuration, or is folded onto itself, or in general occupies a first space,
and in the second configuration the inflatable element is preferably in an extended
condition, or occupies a second space greater than the first space.
[0013] The inflatable element is configured to extend along a distension direction at the
moment of inflation. In other words, the inflatable element is preferably configured
to stretch out, or unfold, or spread out or expand, along said distension direction,
passing from a folded or packed configuration, or configuration where it is folded
onto itself, into an extended or unfolded configuration so as to protect a user, for
example in the event of a fall or imminent impact.
[0014] The personal protection device according to the present disclosure furthermore comprises
a support structure associated with said inflatable element (10) and configured to
support the at least one inflatable element. Said support structure comprises at least
one guide element which is connected to the at least one inflatable element so as
to guide the latter, from the first rest configuration, or deflated configuration,
into the second active configuration, or inflated configuration, along the distension
direction. In other words, the support structure and in particular the guide element
of the latter is configured to ensure guiding during inflation and effective positioning,
for example preferably unfolding, of the inflatable element at the moment of inflation.
The inflatable element is configured to slide along, or is slidably associated with,
said guide element, and said guide element is an elongated element having a development
direction which defines a direction of sliding or distension of the inflatable element.
The guide element is configured to control distension of the inflatable element along
said development direction. In other words, the guide element has a respective development
direction (which is a longitudinal direction) defining said distension direction of
the inflatable element and controlling the direction of extension of the inflatable
element. In yet other words, the support structure and in particular the guide element
of the latter has an intrinsic rigidity and a structure which is independent of the
inflatable element, and therefore of the respective inflated and/or deflated configuration
of the inflatable element, as a result of which the guide element is configured to
control and ensure guiding during inflation and effective positioning, for example
preferably unfolding, of the inflatable element at the moment of inflation.
[0015] In other words, owing to the geometrical arrangement of the parts as defined above,
the "slidable" connection ensures that the inflatable element may be guided by the
guide element.
[0016] In detail, the guide element is configured to favour the transition of the inflatable
element from the rest condition, or deflated condition, to the active condition, or
inflated condition, preferably ensuring effective and uniform unfolding and distension
thereof, guiding it so as to extend along the distension direction and therefore favouring
easy transition of the latter from a folded or packed configuration, or configuration
where it is folded onto itself, to an extended configuration. In this way, advantageously,
the inflatable element may ensure effective protection of a body zone of a user. In
other words, the guide element is an element which allows the distension, or lateral
expansion, of the inflatable element to be controlled.
[0017] In yet other words, according to the present disclosure, the guide element is an
elongated element and the inflatable element is configured to slide along, or is slidingly
associated with, said guide element. In other words, the guide element has a main
development direction which defines a direction of sliding of the inflatable element.
Consequently, advantageously, the guide element defines a direction of sliding of
the inflatable element, wherein the latter may extend, or unfold or unroll from the
deflated or folded-up or packed configuration into the extended configuration.
[0018] It should be noted that preferably the inflatable element is partly attached to,
or stably associated with, a portion of the support structure and partly slidingly
associated with the guide element, and the distension from the rest condition into
the active condition is controlled by the guide element. In other words, preferably
said support structure is attached, in a first region, to said inflatable element
and connected slidingly in a second region by means of the guide element to the inflatable
element. Again preferably, the guide element maintains preferably constantly a same
extended condition along said development direction, or longitudinal direction, or
sliding direction which does not change depending on the inflated or deflated condition
of the inflatable element; on the contrary it is the guide element which conditions,
or controls, the direction of distension of the inflatable element from the deflated
condition, or first rest configuration, into the inflated condition, or second active
configuration.
[0019] According to a preferred aspect of the present disclosure, the guide element is a
band or narrow strip and the inflatable element is configured to define an eyelet
component, or annular component, in which the guide element is slidably inserted.
Expressed differently, the inflatable element is configured to slide, through the
eyelet component, or annular component, on the guide element. Advantageously, the
eyelet component, or annular component, is configured to slidably constrain the inflatable
element, or at least a portion thereof, to the guide element, so that the former may
effectively slide on the latter.
[0020] According to a preferred aspect, the personal protection device according to the
present disclosure comprises an additional layer attached to a surface of the inflatable
element. According to this aspect, said additional layer defines the eyelet component,
or annular component, together with the surface of the inflatable element. In other
words, according to this aspect, the annular component is an element associated with
the inflatable element.
[0021] In accordance with a further aspect of the present disclosure, the inflatable element
comprises a first end portion attached to the support structure, and a second end
portion, opposite to the first end portion. In the rest configuration, or deflated
configuration, the second end portion is at least partially superimposed, or substantially
superimposed, on the first end portion. Said second end portion is configured to cooperate
with the guide element. In particular, the second end portion of the inflatable element
is slidingly associated with the guide element, for example by means of the eyelet
component, or annular component, with which the said second end portion may be provided.
In other words, according to this aspect, the first end portion is associated with
and constrained to the support structure, while the second end portion is slidingly
associated with the guide element so as to be able to slide thereon and pass from
a configuration in which it is superimposed, partially superimposed, or in any case
arranged close to the first end portion, into a configuration in which it is spaced
from, or distant from, or extended, in particular along the distension direction,
from the first end portion of the inflatable element.
[0022] In greater detail, according to a preferred aspect of the present disclosure, the
second end portion of the inflatable element is configured to slide along the guide
element away from the first end portion, along the distension direction. Said movement
corresponds to the transition of the inflatable element form the rest configuration,
or deflated configuration, to the active configuration, or inflated configuration.
In other words, the movement of the second end portion of the inflatable element away
from the first end portion defines a distension, or lateral expansion, along the distension
direction, of the said inflatable element, which passes from a configuration where
it occupies less space, for example being folded up, packed or folded onto itself,
to a condition where it occupies more space, for example being stretched or extended,
in particular laterally extended, along the distension direction.
[0023] According to a preferred aspect of the present disclosure, the support structure
comprises a constraining portion configured to connect the first end portion of the
inflatable element to the support structure. Said constraining portion extends in
a direction transverse to the distension direction. In other words, according to this
aspect, the first end portion is constrained to the support structure along a direction
orthogonal to the distension direction of the inflatable element. In this way, the
second end portion of the latter may be configured so as to unfold, or stretch, away
from the end portion along the distension direction.
[0024] Preferably, according to one aspect of the present disclosure, the support structure
comprises an abutting element configured to act as an end stop for the second end
portion of the at least one inflatable element. According to this aspect, the abutting
element is fixed to an end section of the guide element and has a main development
direction substantially transverse to the distension direction. Advantageously, therefore,
the support structure comprises an abutting element which is configured to limit sliding
along the guide element of the second end portion of the inflatable element.
[0025] According to a further preferred aspect of the present disclosure, the protection
device comprises at least two guide elements, arranged parallel to each other and
each cooperating with a zone of the inflatable element. According to this preferred
aspect, moreover, the second end portion of the inflatable element comprises two eyelet
components, or annular components, each configured to accommodate a corresponding
guide element of the two guide elements. In this way, the distension, or unfolding,
or unrolling of the inflatable element, in particular of its second end portion with
respect to its first end portion, is further favoured and facilitated. The zone of
the inflatable element may be a chest zone. Therefore one guide element may be provided
for a right-hand zone of the chest and one guide element may be provided for a left-hand
zone of the chest.
[0026] Preferably, the personal protection device is an impact protection device and comprises
a pressurized gas source configured to introduce a gas into the at least one inflatable
element for transition of said at least one inflatable element from the rest configuration,
or deflated configuration, to the second active configuration, or inflated configuration.
[0027] The present disclosure also relates to a wearable article which includes a personal
protection device. According to this aspect, the wearable article comprises an exposed
outer surface and an inner surface, opposite to the outer surface, wherein the support
structure is associated, in a fixed or removable manner, with this inner surface.
Advantageously, the support structure may be for example arranged on a zone of the
wearable article designed to cover a back zone of a user, and the guide element may
extend towards a chest zone of the said wearable article, while the abutting element
may be arranged in a zone configured to cover a sternum zone of the user. The wearable
article may also comprise a plurality of inflatable elements, for example two inflatable
elements, for example configured to protect, respectively, a right-hand zone of the
chest and a left-hand zone of the chest of a user. In this sense at least one abutting
element may be placed on a side zone of the chest of the wearable article.
[0028] The present disclosure also relates to a method for protection of a user by means
of a personal protection device. Said method comprises a step of providing at least
one inflatable element configured to assume at least a first rest configuration, or
deflated configuration, and a second active configuration, or inflated configuration.
During the transition from the first configuration to the second configuration, the
inflatable element is guided by means of a guide element, which is an elongated element
having a development direction. The guiding action occurs by causing said at least
one portion of the inflatable element to slide along the development direction of
the guide element and controlling distension of the inflatable element along said
development direction.
[0029] In other words, the guide element has a (predefined) longitudinal extension and a
predefined development direction independent of the deflated configuration and the
inflated configuration of the inflatable element, and the development direction defines,
namely conditions, the distension direction of the inflatable element from the deflated
configuration into the inflated configuration.
[0030] Further advantages, characteristic features and modes of use forming the subject
of the present disclosure will become clear from the following detailed description
of embodiments thereof, provided by way of a non-limiting example.
[0031] It is in any case clear that each embodiment forming the subject of the present disclosure

that each embodiment should have simultaneously all the advantages listed.

[0033] With reference to the accompanying drawings, an embodiment of a personal protection
device for providing personal protection for a user is indicated by the reference
number 100.
[0034] With particular reference to Figures 1, 2, 3, 4, and 5, the protection device 100
according to the present disclosure comprises at least one inflatable element 10.
Said at least one inflatable element 10 is able to assume at least a first rest configuration,
or deflated configuration, and at least a second active configuration, or inflated
configuration.
[0035] The inflatable element 10 comprises a first end portion 11 and a second end portion
12, opposite to the first end portion 11.
[0036] In greater detail, with reference to Figures 1 and 4, in the first rest configuration,
or deflated configuration, the at least one inflatable element 10 is in a configuration
where it occupies a smaller space, for example being folded up, or packed, or folded
onto itself. In detail, in this configuration, or folded configuration, the second
end portion 12 is at least partially superimposed, or substantially superimposed,
on the first end portion 11. In other words, in this deflated condition, the second
end portion 12 is arranged close to the first end portion 11.
[0037] With reference instead to Figures 2, 3 and 5, in the second active configuration,
or inflated configuration, it is in a condition where it occupies more space, for
example an extended or unfolded configuration. In this inflated configuration the
second end portion 12 is located spaced from the first end portion 11 of the inflatable
element 10.
[0038] In particular, according to the present invention, the at least one inflatable element
10 is configured to extend along a distension direction A from the folded, or rest,
or deflated configuration, into the extended, or active or inflated configuration.
In other words, the at least one inflatable element 10 is configured to unfold, or
extend, passing from the folded or packed configuration of Figure 1, in which a second
end portion thereof 12 is superimposed or substantially superimposed on a first end
portion thereof 11, into the expanded configuration in Figure 2, in which said second
end portion 12 is extended, or unfolded, or spaced, from said first end portion 11
along the distension direction A.
[0039] The personal protection device 100 according to the present disclosure furthermore
comprises a support structure 20 configured to support the at least one inflatable
element 10. Basically, the support structure 20 is a structure at least partially
associated with the at least one inflatable element 10, and preferably attached thereto.
For example, the support structure 20 is a kind of frame and may be configured to
associate the at least one inflatable element 10 with a wearable article. In this
sense, the support structure 20 may be associated with said wearable article and configured
to support at least one inflatable element 10.
[0040] In other configurations, the support structure 20 may be fixed to a garment or part
thereof, for example fixed in a pocket of the garment.
[0041] According to the present disclosure, the support structure 20 comprises at least
one guide element 21. Said at least one guide element 21 is connected to the at least
one inflatable element 10 and is configured to guide said inflatable element along
the distension direction A, from the first rest configuration, or deflated configuration,
into the second active configuration, or inflated configuration.
[0042] The at least one guide element 21 is an elongated element of the support structure
20 so as to be able to guide the at least one inflatable element along the distension
direction A. Said at least one guide element 21 therefore has its own development
direction and is independent of the first rest configuration, or deflated configuration,
and of the second active configuration, or inflated configuration of the inflatable
element 10. Said at least one inflatable element 21 is able to condition the distension
of the inflatable element from the rest configuration, or deflated configuration,
into the second active configuration, or inflated configuration.
[0043] Preferably the support structure 20 is attached, in a first region, to said inflatable
element 10 and connected slidably in a second region by means of the guide element
21 to the inflatable element 10.
[0044] For example, the guide element 21 is a band or a narrow strip, for example made of
fabric. Furthermore, according to this aspect, the at least one inflatable element
10 is configured to slide along said elongated element. A sliding direction which
coincides with a distension direction, and which coincides with or is parallel to
the development direction of the guide element 21, is therefore defined.
[0045] Preferably, the at least one inflatable element 10, for this purpose, is configured
to define an eyelet component 23 or annular component. In other words, the inflatable
element 10 is configured to slide along the guide element 21, preferably in the distension
direction, through the annular component, inside which the guide element 21 is inserted.
[0046] In order to be able to extend along the distension direction, expanding or stretching
out from the first configuration to the second configuration, the inflatable element
10 comprises a first end portion 11 attached to the support structure 20, and a second
end portion 12, opposite to the first end portion 11, which is instead configured
to cooperate, for example by means of sliding, with the guide element 21.
[0047] In particular, according to a preferred aspect of the present disclosure, the second
end portion 12 is slidingly associated with the guide element 21.
[0048] Even more preferably, according to an aspect of the present disclosure, the second
end portion 12 of the inflatable element 12, in order to slide along the guide element
21, is provided with the eyelet component 23 or annular component.
[0049] In other words, the first end portion 11 is configured to be associated with the
support structure 20, preferably in such a way that, during the transition from the
first configuration to the second configuration, a relative position thereof with
respect to the said support structure 20 does not change. Expressed in yet other words,
the first end portion 11 is fixed, or constrained, to the support structure 20, for
example by means of a constraining portion 22 of the latter, wherein said constraining
portion 22 extends in a direction which is transverse, or substantially transverse,
to the distension direction A.
[0050] In order to extend along the distension direction A, the second end portion 12 is
configured to slide away from the first end portion 11 along the distension direction
A, in particular along the guide element 21. This movement of the second end portion
12 away from the first end portion 11 of the inflatable element 10 corresponds to
the transition of the latter from the first rest configuration, or deflated configuration,
to the second active configuration, or inflated configuration.
[0051] The distension of the second end portion 12 of the inflatable element 10 with respect
to the first end portion 11 thereof is possible, on the one hand, because the second
end portion 12 is configured to cooperate, preferably by means of sliding, with the
guide element 21 (which, as mentioned, has its own structure and own respective rigidity)
and, on the other hand, because the first end portion 11 is constrained, in a direction
orthogonal to the distension direction A, to the support structure 20, in particular
to the constraining portion 22 thereof. In other words, the distension, or unfolding,
of the inflatable element 10, according to the present disclosure, is allowed by a
movement of the second end portion 12 with respect to the first end portion 11, which
is instead attached to the support structure 20.
[0052] Advantageously, the guide element 21 and the fact that the second end portion 22
is slidable thereon allows the unfolding, or unrolling, of the inflatable element
10 along the distension direction A, in particular in the case where the inflatable
element is arranged in a pocket, or insert of a wearable article, facilitating the
distension or unfolding thereof and therefore improving the protection for a user.
According to a further preferred aspect of the present disclosure, the support structure
20 comprises an abutting element 24. Said abutting element 24 is configured to act
as end stop for the second end portion 12 of the at least one inflatable element 10.
In other words, the abutting element 24 is configured to limit sliding of the second
end portion 12 of the inflatable element 10 on the guide element 21.
[0053] According to this aspect, the abutting element 24 is fixed to an end section of the
guide element 21 so as to limit therefore the sliding of the second end portion 12
on the latter. Preferably, moreover, the abutting element 24 has a main development
direction B which is transverse, or substantially transverse, to the distension direction
A.
[0054] In order to favour further the distension, or unfolding, of the at least one inflatable
element 10 along the distension direction A, the support structure 20 may comprise
two guide elements 21, arranged preferably parallel to each other and each cooperating
with a zone of the at least one inflatable element 10, in particular, with a zone
of the second end portion 12 of the inflatable element 10. In this way, unfolding
of the inflatable element 10 is favoured along its entire dimension orthogonal to
the distension direction A. In other words, according to this preferred aspect, the
at least one inflatable element is arranged, in an unfolding direction A, between
the two guide elements 21. These two guide elements 21, together with the abutting
element 24, define advantageously a confined space for distension or inflation of
the at least one inflatable element 10. Advantageously, moreover, in this configuration,
the abutting element 24 allows the two guide elements 21 of the at least one inflatable
element 10 to be kept spaced, preferably parallel with respect to each other.
[0055] For this purpose, the second end portion 12 comprises two eyelet components, or annular
components, each configured to accommodate a corresponding guide element 21 of the
two guide elements 21.
[0056] According to a further preferred aspect of the present disclosure, the protection
device 100 may comprise two inflatable elements 10, 10', for example configured to
protect a body zone of a user, for example a chest zone. According to this aspect,
each inflatable element 10, 10' of the two inflatable elements may comprise at least
one guide element 21, on which the inflatable element 10 itself is slidable by means
of at least one eyelet element 23 or annular element. In this configuration, preferably
the inflatable elements 10 are configured to extend along a distension direction A
opposite to each other, from the rest configuration, or deflated configuration, into
the second active or inflated configuration. In other words, a first inflatable element
10 is configured to extend along this direction A, towards the second inflatable element
10, while the latter is configured to extend along a direction A', wherein said direction
A' is opposite to the distension direction A of the first inflatable element 10, as
indicated in Figure 3. The distension of each inflatable element 10, 10' is limited
by an abutting element 24 arranged between the two inflatable elements 10, 10'. In
other words, according to this aspect, the abutting element 24 is an end portion of
the at least one guide element 21 of each inflatable element 10, 10'.
[0057] Advantageously, according to this aspect, the abutting element 24 allows distension
of each inflatable element 10, 10' along a respective distension direction A, A' to
be limited. Furthermore, in this configuration, the abutting element 24 prevents the
two inflatable elements 10, 10; from being superimposed, or arranged on top of each
other, for example during inflation of the two inflatable elements 10, 10', therefore
creating a planar protection surface which does have points where an object may penetrate
the body of a user.
[0058] According to a preferred aspect of the present disclosure, the protection device
100 is an impact protection device and more preferably a so-called "stand-alone" device
for protection of a user, namely a device which is provided with all the components
necessary for inflation thereof. An example of such a device 100 which includes all
the aforementioned characteristics is shown in Figures 8 and 9. For this purpose,
said personal protection device 100 comprises a pressurized gas source (not shown
in the drawings) configured to introduce a gas into the at least one inflatable element
10 for transition thereof from the rest configured, or deflated configuration, to
the second active configuration, or inflated configuration. In other words, the pressurized
gas source is configured to inflate the at least one inflatable element 10, wherein
said inflation involves the transition, from the configuration where said the inflatable
element is packed, or folded onto itself, into the unfolded or stretched configuration.
[0059] With particular reference to Figures 6 and 7, the present disclosure relates to a
wearable article 1000 comprising a personal protection device 100 as described above.
Said wearable article may be a protective garment for a user, for example a jacket,
or a suit, for example for motorcycling or skiing, or a protective waistcoat or a
pair of trousers.
[0060] Preferably, said wearable article 100 comprises an exposed outer surface and an inner
surface, opposite to the outer surface and configured, during use, to be directed
towards a user's body. According to this aspect, the support structure 20 is associated
with, for example attached to, the inner surface of the wearable article 1000, or,
as mentioned, a pocket. A pocket is indicated by means of a broken line in Figures
6 and 7, or in Figures 4 and 5.
[0061] The support structure 20 may be part of the garment or the inner surface thereof.
[0062] For example, the support structure 20, in the case where the wearable article 1000
is a waistcoat or a jacket, may be arranged on a back zone of the wearable article
100. According to this aspect, the at least one guide element 21 may extend from this
back zone as far as a chest zone of the said wearable article 1000, where the abutting
element 24 may also be arranged.
[0063] The wearable article 1000 may comprise a personal protection device 100 with two
inflatable elements 10, for example a first inflatable element configured to protect,
during use, a right-hand zone of the chest of a user and a second inflatable element
configured to protect, during use, a left-hand zone of the chest of a user.
[0064] Finally the present disclosure relates to a method for protection of a user by means
of a personal protection device 100.
[0065] During the description of said method, the personal protection device 100 and its
elements will not be further described in detail, and maintain the same reference
numbers indicated above.
[0066] In particular, the method comprises a step of providing at least one inflatable element
10 configured to assume at least a first rest configuration, or deflated configuration,
which occupies less space, and a second active configuration, or inflated configuration,
which occupies more space.
[0067] The method involves the step of mounting said inflatable element 10 on a support
structure 20 which comprises at least one guide element 21.
[0068] Furthermore, the method involves a step of inflating the at least one inflatable
element 10 from the first rest configuration into the second active configuration.
This step preferably causes distension of the at least one inflatable element 10 from
a condition, in which at least one portion thereof is folded onto a further portion
of the inflatable element 10, into a configuration where this portion is extended
with respect to the further inflatable portion 10.
[0069] The method furthermore involves guiding, by means of the guide element 21 of the
support structure 20, the distension of this portion of the inflatable element 10
with respect to the further portion thereof. Essentially, the guide element 21 is
an element configured to control, or guide, distension of a portion of the inflatable
element 10 with respect to a further portion thereof.
[0070] According to a preferred aspect, the inflatable element portion configured to undergo
distension is a second end portion 12 of the inflatable element 10, while the other
portion is a first end portion 11 of the said inflatable element 10. According to
this aspect, the step of inflating the inflatable element 10 involves constraining
the first end portion 11 of the inflatable element to a constraining portion of the
support structure. Preferably, this constraining action is performed a direction transverse
to the distension direction A.
[0071] Furthermore, according to this aspect, the inflation step involves sliding the second
end portion 12 along the guide element 21, in the distension direction A, away from
the first end portion 11.
[0072] In order to perform inflation of the inflatable element 10, the protection device
according to the present invention is able to cooperate with special activation and
inflation means (not shown).
[0073] Alternatively, these means may comprise gas generators of the pyrotechnical or hybrid
type or of other types known in the state of the art,
Operation of said inflation means is controlled by a control unit depending on the
detection of the user's condition; for example, said control unit may implement an
impact prediction algorithm which allows early identification of the event and a reliable
prediction thereof by means of sensors and a unit for processing the signals produced
by the said sensors.
[0074] The aforementioned detection and activation means may also be incorporated in the
protection device according to the present invention or located on the outside thereof.
[0075] Basically, it is to be understood that the impact detection and activation means
of the inflatable element 10 may be either means associated with the user on the outside
of the personal protection device or means incorporated in the latter.
[0076] It should also be noted that the activation methods, while being an aspect of particular
importance for effective operation of the device, will not be described in further
detail since they are methods which are essentially already known to the person skilled
in the art.
[0077] The protection device may also comprise a deflation valve communicating on one side
with the internal chamber of the inflatable element and on the other side with the
external environment, in order to allow the deflation of the inflatable element 10
following activation and when a protective action is no longer required. Activation
of the deflation valve may be controlled by an electronic control unit, which opens
the deflation valve once a predefined time interval from activation of the inflation
means has lapsed. Alternatively, the deflation valve may be manually operated.
[0078] The subject-matter of the present disclosure has been described hitherto with reference
to its embodiments. It is to be understood that other embodiments relating to the
same inventive idea may exist, all of these falling within the scope of protection
of the claims which are provided below.
