FIELD OF THE INVENTION
[0001] The present invention relates to a protective helmet, particularly for motorcyclists,
of the type comprising a shell with a chin guard and an opening for a corresponding
visor, one or more shock absorbing layers internally coupled to the shell and to the
corresponding chin guard, and one or more paddings placed within said shock absorbing
layers, as well as at least one support mask for the shock absorbing layer of the
chin guard, wherein said internal support mask comprises holding means for the shock
absorbing layer of the chin guard and mechanical hooking means to said chin guard.
PRIOR KNOWN ART.
[0002] It is known art to constrain the shock absorbing layer of a protective helmet, normally
made of polystyrene foam (EPS), directly to the inner surface of the helmet shell
by forced restraining (shrinking), gluing, or also by mechanical supporting and clamping
means, or also by way of Velcro ® strips.
[0003] In particular, it is frequent, in the prior known art, to make protective helmets
which present within the shell various juxtaposed shock absorbing layers, presenting
in particular a first hemispherical shaped layer suited to protect the user's cranial
zone against impact, two opposite facing layers arranged for lateral impact protection
of the side regions (cheeks) of the user's face, and optionally a shock absorbing
layer for the protection of the user's chin. These different shock absorbing layers
are usually permanently constrained to the outer shell of the helmet by forced restraining
(i.e. by forced geometric fit).
[0004] Within these shock absorbing layers, also to prevent that undue mechanical actions
may damage them, padding is normally placed, for example, covered in fabric, engaging
the user's face, which also ensures needed comfort of use.
[0005] In the case of a shell comprising a portion of the chin protection, commonly referred
to as chin guard, the shock absorbing layer suited to protect the user's chin, not
only is usually separated from one or other shock absorbing layers, but is also without
external padding, which could disturb the user's breathing and hinder the grip and
hand holding of the helmet.
[0006] Regarding the chin guard, it is known art to cover said shock absorbing layer, particularly
its portion facing the user's chin with a surface cover, for example consisting of
synthetic leather (i.e. a fabric layered with polyurethane PU or a polyamide PA) or
consisting of polyurethane (PU) foam, which is able to prevent or reduce the chance
of accidental damage of said shock absorbing layer as well as being a layer pleasant
to the user's touch.
[0007] This surface cover for the shock absorbing layer of the chin guard, in the common
case where the latter is produced in EPS, is usually made by overprinting (e.g. low
pressure injection) of said shock absorbing layer with an appropriate coating material,
such as polyurethane foam, which defines a layer of limited thickness, for example
equal to a minimum of 2mm, defining the final shape of the piece to allow coupling
with the rest of the components of the helmet, also guaranteeing appropriate stylistic
requirements.
[0008] This art has however certain drawbacks.
[0009] As first, the surface cover layer, for both intrinsic technological limits of the
process of overprinting along with the production process of the shock absorbing layer
in EPS of the chin guard, leads to a final unit weight which may be excessive.
[0010] Secondly, the productivity of this technique is rather low, given the long time needed
to perform overprinting and the further processing of burr removal. Finally, the high
costs needed to achieve such a surface cover by way of overprinting material suitable
for absorbing impact, usually consisting of EPS, should also be mentioned.
[0011] To overcome these disadvantages, it is a known art to use, mainly in helmets with
a raising chin guard, a support mask and surface cover of the shock absorbing layer
of the chin guard which, sandwiched between the user's face and said shock absorbing
layer, is mechanically constrained to said chin guard, so that the shock absorbing
layer remains positioned between said support mask and the inner wall of the chin
guard. See for example
GB 2 186 194 A.
[0012] This support mask, which can be opportunely shaped and fitted with ducts allowing
the guided passage of an air flow from the outside to the inside of the helmet, is
usually a plate-like member made out of an injection molded plastic material (such
as polyethylene (PE) or polypropylene (PP), or also thermoplastic polyurethane (TPU)),
including both the hooking means to the chin guard, formed for example by screws,
bolts or elastic-type couplings, and also by holding means of the shock absorbing
layer of the chin guard, made for example by portions and shaped strikers or elastic
tabs or other elements designed to execute mechanical constraining of said shock absorbing
layer.
[0013] The use of this support mask of the shock absorbing layer makes no longer necessary
the overprinting operation of the said absorbing layer, usually in EPS, with a thin
layer of a coating material, such as PU foam.
[0014] However, the encumbrance of a support mask of the kind described above requires careful
designing of internal parts of the helmet shell, which must be shaped and constrained
together in a way allowing installation and correct housing of said support mask.
[0015] Particularly, the layout and the conformation of the fixing means of the padding
to the shock absorbing layer placed near the chin guard, and therefore of said support
mask, must be carefully studied.
[0016] Additionally, it should be mentioned that, in protective helmets of recent production,
the padding that is sandwiched between the head and user's face and the shock absorbing
layer (EPS) is usually constrained to this last layer by temporary coupling means,
to allow the user, whenever necessary, to easily detach and eventually reattach any
padding from the shock absorbing layer, in order to perform cleaning or replacement
of said padding.
[0017] More specifically, these temporary, or reversible, coupling means of the padding
usually comprise fixing plates, glued to the shock absorbing layer, which bear strikers
for complementary buttons or hooks built into the corresponding portions of the padding.
[0018] As will be clear to a person skilled in the art, the use of fixing plates glued to
the shock absorbing layer, usually polystyrene foam, and corresponding snapping buttons
(clips) or other types of couplings attached to the padding, as temporary coupling
means still requires processing, packaging or assembly of various components either
on the shock absorbing layers, or on the comfort padding, that normally prove to be
very expensive, and require a degree of practicable precision to allow simple assembly,
guaranteed over time.
[0019] It is an aim of the present invention to realize a protective helmet of the type
described above which at least partially will solve the problems of the prior art
expressed above.
[0020] It is therefore the aim of the present invention to provide a protective helmet with
a support mask for the shock absorbing layer of the chin guard to allow the temporary
coupling (reversible) of at least part of the inside padding of the helmet, placed
closely to the chin guard, provided in an effective and simple way.
[0021] A further purpose of the present invention is to provide a protective helmet equipped
with a chin guard by way of an economical and quick production process, providing
a wide choice of finishes and shapes within the chin guard, while requiring a smaller
amount of components.
SUMMARY OF THE INVENTION
[0022] These and other aims are achieved by the protective helmet according to the first
independent claim and the additional dependent claims.
[0023] The protective helmet according to the present invention comprises a shell with a
chin guard and an opening for a visor, one or more shock absorbing layers, internally
coupled to said shell and said chin guard, and one or more paddings inside said shock
absorbing layers, as well as and at least an internal support mask for a shock absorbing
layer of the chin guard. This support mask also comprises respective holding means
of the shock absorbing layer of the chin guard, and hooking means to the chin guard.
Advantageously, the support mask also comprises temporary coupling means of at least
one of the aforesaid paddings.
[0024] The integration, in the support mask of the shock absorbing layer of the chin guard,
of temporary coupling means of the padding, especially those set for engaging the
user's cheeks, simplifies the design of the constraints to the helmet of said padding
arranged in proximity of the chin guard, providing temporary coupling means that are
highly effective and stable during use - since it is not required any gluing operation
to the shell to achieve these coupling means - and reduces the number of components
and assembly operations of the product.
[0025] According to a preferred aspect of the present invention, the aforesaid temporary
coupling means of the padding may be of an elastic coupling of complementary parts
type, or of the type comprising a geometric fit coupling between parts belonging to
the aforesaid support mask.
[0026] For example, said temporary coupling means can be constituted of at least one hook
and one relative striker respectively integral to a padding and to said support mask.
[0027] It should be noted that not necessarily said temporary coupling means of at least
one padding to the support mask of the shock absorbing layer of the chin guard achieve
a stable mechanical fixing between these components (i.e., a constraint not easily
releasable by the user), as even the loosely coupled joint (i.e. a constraint easily
releasable by the user) between these latter, even joined by a traditional fixing
(for example by Velcro® strips to the padding and to the corresponding shock absorbing
layer), provides a solution which results in an easier and less expensive assembly
of the padding in question within the shell, and a significant reduction in the number
of components necessary to provide such fixing.
[0028] According to another aspect of the present invention, the support mask may moreover
include ducts for the passage of air flow and/or constraining means for additional
external accessories of the helmet, such as for example a lower windscreen or a diffuser
for an upper airflow.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE PRESENT INVENTION
[0030] With reference at first to Figure 1, the helmet 100 of the present invention comprises,
as known in the art, an outer shell 101, for example, injection molded in a polycarbonate
(PC), shaped so as to define an opening 103 for a visor, and provided with a protection
portion of the chin, commonly called a chin guard, 102, which is located below the
opening 103 and can be obtained as a whole piece, or removable or irremovably fixed
to the remaining part of the shell 101.
[0031] The helmet 100 moreover includes one or more layers 10, 104, 107 of a material suited
to absorb possible impacts (shocks), such as polystyrene foam (EPS), fixed inside
the shell 101, 102, for example through forced restraining (shrinking) between parts
or trough gluing, and one or more paddings 105, 106, also joined inside the shell
101, and arranged to be sandwiched between the user's head and one or more shock absorbing
layers 104, 107. In particular, the helmet 100 provides that, for manufacturing reasons,
there is at least a first homogeneous shock absorbing layer 104, placed below said
portion of the shell 101 destined to protect the user's skull, at least two side layers
107, facing the area of the user's cheeks and at least one additional shock absorbing
layer 10, differing from the first layer 104 and from the two side layers 107, and
placed correspondingly to the portion of the chin guard 102.
[0032] The shock absorbing layer 10 of the chin guard, which can then be glued to the inner
surface of the chin guard 102, is supported within said chin guard 102, according
to the present invention, by a proper support mask 1, shaped so as to retain the shock
absorbing layer 10 and to be easily constrained to the same chin guard 102, or to
the remaining part of the shell 101.
[0033] More in detail, according to a preferred aspect of the present invention, said support
mask 1 of the shock absorbing layer comprises, with particular reference to Figures
2 to 4, a frontal surface 5, shaped so as to provide accommodating and supporting
regions to the relative shock absorbing layer 10, an upper frame 4 and a lower region
3, operating as guides to said layer 10, as well as tabs 2a, 2b, conformed to mechanically
retain said layer 10, by contrasting (overlapping) of parts, following a relative
elastic deformation. The tabs 2a, 2b, the frame 4 and the lower region 3, in addition
to the particular shape of the surface 5, form the appropriate retaining means of
the shock absorbing layer 10 of the chin guard 102.
[0034] Also referring to figure 7, it is noted that the frame 4 of the mask 1 may also have,
obtained as a whole piece, ducts for the passage of a direct air flow from outside
the helmet, through appropriate air inlets, towards the inside of the helmet.
[0035] At the same time, the lower region 3 of the mask 1 can have, obtained as a whole
piece, or defined by the coupling effect with the lower edge 109 of the shell, seats
capable of receiving the hooking of other accessories to be optionally installed in
the lower zone of the helmet such as a wind screen tab, a deflector of aerodynamic
flow, or appendices aimed to reduce the noise generated by vortices which generate
in this area during normal use of the helmet, especially when used with motorcycles
or other locomotive means without full covered chassis. Referring particularly to
Figures 4 and 5, the mask 1 also includes some lateral protuberances 9a, 9b which
constitute hooking, or constraining, means, of the said mask 1 to appropriate complementary
regions 91 a, 91 b, placed within the chin guard 102, formed to hold, by geometric
fit coupling, the aforementioned protuberances 9a, 9b. These hooking means 9a, 9b,
91 a, 91 b of the mask 1 to the inner surface of the chin guard 102 may be alternatively,
according to the known art, of the restraining type, or of the juxtaposition/contrasting
type or of the elastic coupling of complementary parts type, or even of the type with
screwing of screw-threaded parts.
[0036] Note however that, in alternative embodiments not shown here, those hooking means
can also be formed by one or more layers of glue binding the mask 1 to the chin guard
102, or to the remaining part of the shell 101, directly or by the sandwiching of
the shock absorbing layer 10.
[0037] It should also be noticed that, as already mentioned, to the mask 1 further external
accessories may be attached, for example one or more diffusers for airflow directed
within the helmet, held to the mask 1 by appropriate mechanical holding means, similar
to those specified for the hooking means 9a, 9b to the chin guard 102.
[0038] More in detail, as shown in Figure 7, the hollow space between the seal of the lower
edge 109 of the chin guard portion 102 of the shell and the lower edge 3 of the mask
1 may act as a seat in which to insert, for example, a shaped tab to which can conveniently
be fixed an aerodynamic appendage or a wind screen flap or any other accessories that
can be housed in the lower region of the helmet.
[0039] As is particularly visible in figures 4 and 5, 8 and 9, further, the mask 1 comprises,
corresponding to its inner wall 7, i.e. the wall destined to face the user's chin,
means 6a, 8a, 61 a, 6b, 8b, 61 b destined to temporary or reversible fixing of at
least one of the aforesaid paddings 105, 106.
[0040] These means of temporary coupling, in the embodiment shown here, are composed of
a through-slot 61A, 61 b at the center of which is a flange 6a, 6b which protrudes
towards the inside of the helmet, a pin, or a striker, 8a, 8b intended to engage with
a complementary hook, or fork, 108a (see Figures 8 and 9) presented by at least one
corresponding paddings 106.
[0041] As seen in detail in Figures 8 and 9, which respectively show the coupling of a side
padding 106 (cheek pad) with the corresponding end of the support mask 1 and the same
side padding 106, said fork 108a may consist of a plastic tab fixed at the front portion
of the padding 106, which is likely to be inserted within the through-slot 61 a, to
be engaged, achieving a stable mechanical fastening or in a way to achieve a loose
coupling, with the corresponding pin 8a.
[0042] It is in fact seen that the engagement of each fork 108a with its corresponding pin
8a (or 8b) may for example be of an elastic type, so as to directly facilitate the
mechanical fixing between padding 106 and support mask 1, or it can be of a loose
type, such as a hook for example in which the fork 108a is extractable in a given
direction.
[0043] In this latter case, as already mentioned, for obtaining the fixing of the padding
106 to the shell 101 of the helmet, it will be necessary to place traditional fastening
means of the padding 106 to the corresponding shock absorbing layer 107, as clips
or Velcro® strips.
[0044] It should be noted, however, that the coupling between the padding 106 and mask 1,
even if loose, allow an easy assembly of said padding, as well as a significant reduction
in the number of components necessary to secure the padding 106 itself.
[0045] Alternatively, in embodiments of the present invention not shown here, the temporary
or reversible coupling means, for at least one padding 106 may be of the elastic coupling
of complementary parts type, such as snap buttons, clips, etc.., or be of the counterpart
hooking type, such as buttons and buttonholes, or even of the type comprising male
and female Velcro® strips placed respectively on mask 1 and on corresponding portions
of the padding 106.
[0046] Again, these coupling means can consist of guides and engaging slides within said
guides, or other known types of loose coupling, i.e. with at least a certain degree
of freedom, not discussed here.
[0047] According to a particular aspect of the present invention, the helmet 100 shown herein
may include a plurality of paddings 105, 106 flanking each other, in such a way that
at least a padding 106, or a pair of said paddings, is arranged so as to cover at
least part of the sides of the opening 103 for the visor, substantially engaging the
user's cheeks when the helmet 100 is worn, until reaching the chin guard 102, or more
precisely its corresponding support mask 1 for the shock absorbing layer 10.
[0048] In this case, the temporary coupling means 6a, 8a, 61 a, 6b, 8b, 61 b of mask 1 to
support the shock absorbing layer 10 of the chin guard 102 are designed to hold said
side padding 106 suitable to engage the user's cheeks.
[0049] Finally, as already known in the art, the mask 1 may be made of polyethylene (PE)
or polypropylene (PP), or even polyurethane (TPU)) by way of injection molding.
[0050] After inserting the inner shock absorbing layer 104 of the user's cranial area within
the outer shell 101, the assembly of the support mask 1 for a shock absorbing layer
10 of the chin guard 102, according to the particular embodiment of the present invention
shown here, first provides that the shock absorbing layer 10 is supported and held
onto the mask by holding means 3, 4, and in particular thanks to the tabs 2a, 2b intended
to retain by contrasting parts the layer 10, and therefore mask 1, with the layer
10, is hooked to the chin guard 102, by way of the protuberances 9a, 9b coupling with
the aforesaid complementary internal regions 91a, 91 b of said chin guard 102;
[0051] Finally, the assembly of the helmet provides that the shock absorbing layers 107
intended to protect the user's cheeks are inserted between mask 1 and the shock absorbing
layer 104, by way of force fit coupling (forced restraining) achieved between the
rear support surfaces, against the inner shell 101, and frontal surfaces, against
the mask 1, as well as the inner shape of the shell 100, resulting in the final locking
of the shock absorbing layers within the helmet.
[0052] At this point the constraining of the padding 105 of the cranial area of the shell
101 to the corresponding shock absorbing layers 104, 107 can be made, and then successively
the positioning and hooking of the side padding 106 to the same mask 1 can be made,
thanks to the temporary coupling means 6a, 8a, 61 a, 6b, 8b, 61 b, 108a, thus obtaining
the complete assembly of the inner parts of the helmet.
[0053] As previously underlined, in the case of loose temporary coupling means, i.e. not
defining a complete mechanical fastening of the side padding 106 to mask 101, such
a solution facilitates in any case the installation of said padding 106 and reduces
the number of traditional fixing elements, such as elastic clips or Velcro® strips
between the shock absorbing layer 107 and the inner walls of the padding 106.
[0054] However if the hooking of the padding 106 directly to the mask 1 also accomplishes
the mechanical fixing of said padding 106 to the mask 1, i.e. by way of elastic coupling,
this solution eliminates the necessity to create more hooking means for said padding
directly on the inner walls of the shell, making the building of the helmet cheaper,
and simplifying construction and assembly.
