[0001] The present disclosure relates in general to the technical sector of protective helmets.
More particularly, the present disclosure relates to an inner liner, also called conventionally
an "inner", for protective helmets, which is arranged inside an outer cap of a helmet
and is intended to be arranged between the cap and the head of a user.
[0002] In particular, in the context of the present description and in the following claims,
the term "inner liner" of a helmet is understood as meaning an assembly including
a generally soft padding which serves to cover, at least partially, an inner or concave
side, or intrados side, of the cap (wherein the cap includes, usually and conventionally,
a shell and a layer made of polystyrene, or some other foam material having an energy-absorbing
function).
[0003] The padding acts as a soft layer for ensuring the comfort of the user's head. In
fact, the padding is in direct contact with the head and for this purpose should ensure
the best possible comfort. The material from which the padding is made is therefore
chosen so as to be as soft and comfortable as possible. This inner liner may also
include so-called cheek protectors.
[0004] The inner liner is moreover fixed to the intrados side of the cap, for example, by
means of Velcro™, press-studs or similar fixing or joining systems.
US2009/158506 A1 discloses for instance a liner disposed between an outer shell and an energy-absorbing
layer of a helmet.
[0005] The present disclosure is based on the realization by the author that an inner liner
for helmets of the known type has a limited functionality.
[0006] For example, a liner for helmets of the known type does not ensure optimum comfort
in every season.
[0007] In fact, in the summer, the inner liner should be made of a material able to provide
a sufficiently cool sensation, such as a lining made of lycra or polyester, while
in the winter a warmer material, such as a velvet, may be more convenient.
[0008] In an attempt to overcome this drawback it has been proposed providing a plurality
of paddings which are made of different materials and which are suitable for different
seasons. However, this choice results in the need to use at least two paddings and
therefore constitutes an inconvenience for the user who must always have available
two different accessories for the same helmet.
[0009] A technical problem forming the basis of the present disclosure consists in providing
an inner liner for a helmet and a helmet including such an inner liner, which is able
to overcome at least one of the aforementioned drawbacks and/or which provides a number
of advantages.
[0010] This technical problem is solved by an inner liner for helmets as defined in the
independent claim 1 and by a helmet according to claim 12.
[0011] Basically, the present disclosure is based on the idea of separating or making the
elements for fixing the padding structurally independent of the structure of the padding
itself. In this way, once the inner liner has been detached from the respective cap,
the fixing elements may in turn be detached from the padding. The padding may then
be handled separately from the fixing elements and for example turned inside out so
as to change the side of the padding facing the intrados side of the cap.
[0012] Basically these fixing elements are elements which allow, on the one hand, temporary
and removable fixing, and, on the other hand, constitute fixing elements which are
per se removable, namely are elements which are structurally independent and may be
individually handled.
[0013] The cap may be of the conventional type including a polystyrene layer and an outer
cap, or may be cap having layers different from those of the conventional cap. The
cap is to be regarded as an element having mainly a protective function for a user's
head, for example an energy-absorbing function and/or a function of preventing the
penetration of a foreign body.
[0014] The term "padding" is understood in the context of the present disclosure as referring
to a generally soft structure, with a cap-like or concave shape, which can be handled
manually and which may be entirely or partly devoid of fixing elements intended for
temporary or reversible fixing of the padding to the cap. The padding may also be
a structure with cavities or incisions, namely with empty weight-reducing zones or
spaces. Alternatively, it may consists of a solid, soft, cap-shaped structure.
[0015] The padding may be understood as being a layered structure, i.e. including an inner
pad, and one or more layers which externally line the inner pad. The pad may also
be a multilayered structure. Alternatively, the pad may be without a liner and also
made as a single layer or two layers joined together. Preferably, the padding includes
the liner and even more preferably the liner is different for the sides of the padding.
What is important for the present disclosure is that the padding has two sides, i.e.
an intrados side facing the user's head, and an extrados side facing the cap.
[0016] The fixing elements may be associated with the padding so as to have a coupling portion
facing an extrados side, for allowing (removable) fixing with a coupling counter-element
or fixing counter-portion associated with the cap.
[0017] Owing to the fact that the fixing elements are structurally independent and are detachable
with respect to the padding, they may be removed, and the padding may be inverted
or reversed so that the intrados side becomes the extrados side and vice versa. The
fixing elements may then again be associated with the padding, for example so that
the coupling portion faces again the new extrados side, and allow fixing to the cap.
It should be noted that, if they were not removable, the fixing elements would remain
on the intrados side or facing the intrados side of the padding, causing discomfort
for the user.
[0018] An increased functionality of the padding may therefore be obtained.
[0019] For example the padding may be of the reversible type, and therefore be made so as
to have one side made of a material which is cooler and one side made of a material
which is warmer; in general the padding may be made of two different materials, so
that the extrados side is different from the intrados side.
[0020] Alternatively, the padding may be simply reversible, without differentiation of the
material, and may be turned over or inverted so as to change the side in contact with
the head.
[0021] Other advantages of the separate structure of the padding and fixing elements is
that the padding may be washed separately from the fixing elements which may be retained
and thus are subject to less wear due to cleaning.
[0022] The padding may also be replaced separately from the fixing elements. The fixing
elements may therefore be used for different paddings. The padding may also have a
lower cost and the fixing elements may be made with a more solid structure which ensures
a greater resistance and mechanical strength over time.
[0023] In one embodiment of the present disclosure, the fixing elements are configured to
allow a male/female type connection with the cap. Preferably, the fixing elements
have a structure which has a substantially T-shaped or mushroom-like cross-section,
namely they consist of elements which have a hat portion or, head portion, and a stem
or shank portion. The hat portion is a preferably flat or substantially plate-like
portion, suitable for being positioned on an intrados side of the padding and limiting
as far as possible any discomfort for the user. The stem portion is configured at
one end for fastening with a coupling counter-portion associated with the cap.
[0024] The fastening may be a press-stud or Velcro™ fastening or similar reversible fastening
known to the person skilled in the art.
[0025] Preferably, the padding is provided with holes intended to receive at least partially
the fixing element, and preferably the aforementioned stem portion. For example, when
the fixing element is configured with a T-shaped cross-section, the fixing element
is inserted inside the hole so that the hat portion is on the intrados side and comes
into contact with an inner side of the portion of the padding surrounding the hole.
The stem portion has an end facing the extrados side and ready for coupling with the
counter-portion associated with the cap.
[0026] When it is required to reverse the padding, the fixing element is extracted towards
the intrados side and inserted again on the opposite side of the padding.
[0027] In one embodiment of the present disclosure, in order to damage as little as possible
the padding following the continuous insertion and extraction of the stem portion
of the fixing element, or in general repeated removal of the fixing element, the padding
has a more rigid or reinforced zone around the hole, such as that defined above, intended
for example to receive the stem portion. This greater rigidity may be obtained by
means of gluing together of the layers which form the padding around the hole and
preferably thermoforming of the layers with compression and pressing together of the
same.
[0028] Other characteristic features and modes of use of the subject of the present disclosure
will emerge more clearly from the following detailed description of a number of preferred
embodiments thereof, provided by way of a non-limiting example. It is nevertheless
evident how 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.
[0029] It is also understood that the scope of the present disclosure includes all the possible
combinations of the embodiments indicated above and of those described with reference
to the following detailed description.
[0030] Reference will now be made to the figures in the attached drawings in which:
- Figure 1 shows an axonometric view, with parts disassembled, of an inner liner for
a helmet according to an embodiment of the present disclosure;
- Figure 2 shows a view of a partially cross-sectioned detail of the inner liner for
a helmet according to Figure 1;
- Figure 3 shows a cross-sectional view along the line III-III of Figure 2;
- Figure 4 shows a view of a helmet including the inner liner for a helmet according
to Figure 1.
[0031] With reference to the attached figures, the reference number 10 indicates an inner
liner, also called "inner", for a helmet 12 according to the present disclosure. The
helmet 12 includes an outer rigid cap 14 which includes, in turn, for example, a layer
15 made of polystyrene or other foam or non-foam material with an energy-absorbing
function, and a shell 17, for example with a smaller thickness than the polystyrene
layer 15 (Figure 4) and having an anti-penetration function. The cap 14, the polystyrene
layer and the shell 17 are elements known to the person skilled in the art and will
not be further described in the continuation of the present description. The cap 14
may be made using any manufacturing method and is to be regarded as being a device
including at least one layer having an energy-absorbing function and/or one layer
having an anti-penetration function, namely a function ensuring protection against
the penetration of a foreign body. The inner liner for a helmet according to the present
disclosure is designed to be connected and fixed, for example, to the layer having
an energy-absorbing function and/or to the layer with an anti-penetration function.
[0032] The inner liner 10 is able to be arranged between the head of user and the cap 14.
This inner liner 10 includes a padding 13 which is a generally soft structure intended
therefore to br curved in the form of cap so as to adhere to the form of a user's
head.
[0033] More particularly, in the example shown, the padding 13 includes a pad 16 made of
soft and yielding material, for example foam material, even more particularly, for
example, polyurethane (PU) with a density of 21 kilogrammes/m
3.
[0034] The pad 16 is in turn lined with a first layer 18, or outer layer, made of a first
material, and a second layer 19, or inner layer made of a second material.
[0035] The first layer 18 and the second layer 19 define two opposite sides of the padding
13.
[0036] Even more preferably, the pad 16 may include in turn two layers, i.e. a first layer,
for example a sponge combined with the first material, for example a winter material,
such as velvet-like material, and a second layer, for example a second sponge, combined
with a second lining material, such as a cooler fabric. The two lining materials may
then be stitched together to create the padding 13.
[0037] In other words, the first layer 18, the second layer 19 and the inner pad 16 (which
may in turn be formed by several layers) form a multilayer structure which is suitably
stitched and shaped so as to define an intrados side and an extrados side of the padding.
The intrados side is intended to face the inside or the user's head, while the extrados
side is intended to face the cap 14.
[0038] It is to be understood that further layers and/or reinforcing elements or plate-like
elements - not mentioned in the present description and/or not shown in the disclosure
drawings - may be provided and arranged between the first layer 18, the second layer
19 and the inner pad 16.
[0039] Preferably, the padding 13 is reversible, namely it may be turned inside out so that
an intrados side becomes an extrados side of the padding and vice versa and both the
sides or layers of the padding may be attached to an intrados side of the cap 14.
[0040] In order to fix the padding 13 to the cap 14, the inner liner 10 includes one or
more fixing or coupling elements 20 which are structurally independent of the padding
13. In other words, these elements are elements which may be individually handled
separately from the padding 13. The fixing elements 20 include coupling portions 30
which are able to be connected and/or coupled reversibly or removably together with
coupling or fixing counter-portions 32 fixed to the cap 14 (the coupling counter-portions
32 are indicated generally in Figure 4). For example, the fixing elements 20 include
a coupling portion of a press-stud suitable for connection with a connecting counter-portion
of the press-stud. Alternatively, the fixing elements include a connecting portion
of a Velcro™ connection or similar connection of the reversible type.
[0041] Owing to the fact that the fixing elements 20 are elements which are structurally
independent of the padding 13, these fixing elements may be temporarily associated
with the padding 13, for example so that the coupling portion 30 faces the extrados
side of the padding 13 and therefore emerges from the extrados side and a connection
with the coupling portion 32 associated with the cap 14 is possible.
[0042] A portion of the fixing element 20 may remain on an intrados side and preferably
be shaped so as to create minimum inconvenience for a user.
[0043] For example, preferably, each fixing element 20 has a form with a T-shaped cross-section
and includes a first portion 24 able to be associated with an extrados side, and a
second portion 25 able to be associated with an intrados side. An intermediate portion
26 is arranged between the first portion 24 and the second portion 25. The first portion
24 and the intermediate portion 26 form the shank or stem of the "T". Preferably,
the intermediate portion 26 has a diameter or generally a size smaller than that of
the second portion 25 and preferably smaller also than the first portion 24.
[0044] The second portion 25 may have a substantially plate-like or generally flat form
so as to create the minimum volume or projection on the head side. Preferably the
second portion 25 is provided with a comfort fabric or similar layer suitable for
contact with the head. The first portion 24 has at one end the connecting or coupling
portion 30 for allowing connection with the connecting counter-portion 32 associated
with the cap 14.
[0045] The fixing element 20 may be inserted in corresponding holes or recesses 35 formed
in the padding 13. The fixing element 20 is inserted via the side of the first portion
24 so that the second portion 25 is retained on the intrados side (coming into contact
therewith), and the connecting or coupling portion 30 projects from the extrados side
for fixing together with the cap 14. It should be noted that the first portion has
dimensions such as to have a diameter larger than the hole 35 and allow the fixing
element to remain stably engaged with the padding 13.
[0046] The first portion 24 therefore forces slightly the hole 35 at the moment of insertion.
[0047] Preferably, in an embodiment such as that shown in the drawings, in order to reduce
as far as possible the risk of damaging the padding 13, the latter includes a zone
36 around each hole 35 which is more rigid or reinforced with respect to the remaining
part of the padding 10. For example the more rigid zone 36 or localized reinforcement
may be obtained by means of gluing of the layers which form the padding, for example
by means of thermoforming.
[0048] The reinforcement may be obtained by means of other techniques known in the sector,
such as stitching, or using plastic elements which form a collar or annular band around
the hole.
[0049] The advantage of gluing, in particular by means of thermoforming, is that the reinforcement
may be obtained very rapidly and without using additional elements, which may weigh
down the structure.
[0050] It is also pointed out that, when gluing, thermoforming or also stitching of the
layers of the padding 13 is performed compression of the layers which form the padding
13 is also obtained. Such a compression around the hole 35 allows the thickness of
the padding to be reduced and in fact a recess 37 to be created in the padding 13
around the hole 35. This recess allows seating of the second portion 25 of the fixing
element 20, incorporating it substantially within the general volume of the padding
13 and therefore reducing the risk that the second portion 25 of the fixing element
20 may be "sensed" by a user.
[0051] It is also pointed out that the recess 37 is present on both sides of the padding
13, and therefore both on the intrados side and on the extrados side, and its function
may therefore be used in both the configurations of the padding 13.
[0052] Preferably, in order to reinforce further the hole 35 and prevent tearing when the
fixing element 20 is inserted/extracted, the inner liner 10 may include plate-like
elements made of plastic more rigid than the padding 13. The plate-like elements may
be inserted between the two layers which form the pad 16 and stitched to the edge
of the inner liner 10. The plate-like elements may provide the inner liner 10 with
a further reinforcement for any further machining which must be carried out on the
inner liner 10.
[0053] Preferably, in an embodiment such as that shown in the drawings, the first material
of the first layer 18 is preferably different from the second material. The first
material is for example a warmer material, namely a material suitable for providing
the user with a warm sensation around their head. For example, said material may consist
of a velvet-like material. The second material of the second layer 19 may be a material,
so-called cool material, namely able to provide the user with a cool sensation around
their head, such as a nylon, cotton, linen or other fabric lining, i.e. so-called
cool fabrics, or it may be a breathable and/or perforated fabric.
[0054] Thus, since the padding 13 may be freed of the fixing elements 20 and turned inside
out in a reversible manner, the padding may be reversed depending on the season and
sensation which the user wishes to have. Alternatively, it is also possible for the
first layer 18 and the second layer 19 to be made of the same material and for the
padding 13 to be reversed only in order to change the side on which the head makes
contact with the padding 13.
[0055] In order to perform reversal of the helmet inner 10, the following manoeuvres may
be performed:
Initially, the fixing elements 20 are housed inside the holes of the padding 13 and
fixed to the cap so that each second portion 25 faces the intrados side of the helmet
inner.
[0056] Then the fixing elements 20 are detached from the cap 14, by simply releasing the
removable fastening with the cap 14. Then the padding 13 is reversed so that the extrados
side becomes the new intrados side and vice versa, and the fixing elements 20 are
extracted from the associated holes and inserted via the new intrados side until the
second portion 25 comes into abutment against the side of the padding in the more
rigid zone 36.
[0057] The fixing elements 20 are then ready again for being fixed to the cap 14.
[0058] The subject-matter of the present disclosure has been described hitherto with reference
to preferred embodiments thereof. 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.
