Definitions
- 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.
- EPS polystyrene foam
- 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.
- 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.
- 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.
- synthetic leather i.e. a fabric layered with polyurethane PU or a polyamide PA
- PU polyurethane
- 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.
- an appropriate coating material such as polyurethane foam
- 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.
- 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.
- PE polyethylene
- PP polypropylene
- TPU thermoplastic polyurethane
- 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.
- the padding that is sandwiched between the head and user's face and the shock absorbing layer 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.
- 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.
- 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.
- 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.
- the support mask also comprises temporary coupling means of at least one of the aforesaid paddings.
- 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.
- 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.
- 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.
- 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.
- 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.

Description
- 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.
- 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.
- 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).
- 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.
- 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.
- 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.
- 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.
- This art has however certain drawbacks.
- 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.
- 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.
- 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 - 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- These and other aims are achieved by the protective helmet according to the first independent claim and the additional dependent claims.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Now herein will be described, by way of example only and without limitation, a preferred embodiment of the present invention referring to the attached figures, in which:

Figure 8 is a side view in cross-section of the protective helmet of the previous figures, pointing out the temporary coupling means of a side padding destined to line a user's cheek (cheek pad) to the support mask of a shock absorbing layer of the chin guard, according to a particular aspect of the present invention, in which said side padding is not yet coupled to the relative support mask; and -
Figure 9 is a side view of the padding for the user's cheek infigure 8 , pointing out the temporary coupling means to the aforesaid support mask. - With reference at first to
Figure 1 , thehelmet 100 of the present invention comprises, as known in the art, anouter shell 101, for example, injection molded in a polycarbonate (PC), shaped so as to define anopening 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 theshell 101. - The
helmet 100 moreover includes one ormore layers shell more paddings shell 101, and arranged to be sandwiched between the user's head and one or moreshock absorbing layers helmet 100 provides that, for manufacturing reasons, there is at least a first homogeneousshock absorbing layer 104, placed below said portion of theshell 101 destined to protect the user's skull, at least twoside layers 107, facing the area of the user's cheeks and at least one additionalshock absorbing layer 10, differing from thefirst layer 104 and from the twoside layers 107, and placed correspondingly to the portion of thechin guard 102. - The
shock absorbing layer 10 of the chin guard, which can then be glued to the inner surface of thechin guard 102, is supported within saidchin guard 102, according to the present invention, by aproper support mask 1, shaped so as to retain theshock absorbing layer 10 and to be easily constrained to thesame chin guard 102, or to the remaining part of theshell 101. - 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 toFigures 2 to 4 , afrontal surface 5, shaped so as to provide accommodating and supporting regions to the relativeshock absorbing layer 10, anupper frame 4 and alower region 3, operating as guides to saidlayer 10, as well astabs layer 10, by contrasting (overlapping) of parts, following a relative elastic deformation. Thetabs frame 4 and thelower region 3, in addition to the particular shape of thesurface 5, form the appropriate retaining means of theshock absorbing layer 10 of thechin guard 102. - Also referring to
figure 7 , it is noted that theframe 4 of themask 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. - At the same time, the
lower region 3 of themask 1 can have, obtained as a whole piece, or defined by the coupling effect with thelower 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 toFigures 4 and5 , themask 1 also includes somelateral protuberances mask 1 to appropriatecomplementary regions chin guard 102, formed to hold, by geometric fit coupling, theaforementioned protuberances mask 1 to the inner surface of thechin 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. - 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 thechin guard 102, or to the remaining part of theshell 101, directly or by the sandwiching of theshock absorbing layer 10. - 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 themask 1 by appropriate mechanical holding means, similar to those specified for thehooking means chin guard 102. - More in detail, as shown in
Figure 7 , the hollow space between the seal of thelower edge 109 of thechin guard portion 102 of the shell and thelower edge 3 of themask 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. - As is particularly visible in
figures 4 and5 ,8 and 9 , further, themask 1 comprises, corresponding to itsinner 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 theaforesaid paddings - 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 aflange Figures 8 and9 ) presented by at least onecorresponding paddings 106. - As seen in detail in
Figures 8 and9 , which respectively show the coupling of a side padding 106 (cheek pad) with the corresponding end of thesupport mask 1 and thesame side padding 106, saidfork 108a may consist of a plastic tab fixed at the front portion of thepadding 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 thecorresponding pin 8a. - It is in fact seen that the engagement of each
fork 108a with itscorresponding pin 8a (or 8b) may for example be of an elastic type, so as to directly facilitate the mechanical fixing betweenpadding 106 andsupport mask 1, or it can be of a loose type, such as a hook for example in which thefork 108a is extractable in a given direction. - In this latter case, as already mentioned, for obtaining the fixing of the
padding 106 to theshell 101 of the helmet, it will be necessary to place traditional fastening means of thepadding 106 to the correspondingshock absorbing layer 107, as clips or Velcro® strips. - It should be noted, however, that the coupling between the
padding 106 andmask 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 thepadding 106 itself. - 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 onmask 1 and on corresponding portions of thepadding 106. - 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.
- According to a particular aspect of the present invention, the
helmet 100 shown herein may include a plurality ofpaddings padding 106, or a pair of said paddings, is arranged so as to cover at least part of the sides of theopening 103 for the visor, substantially engaging the user's cheeks when thehelmet 100 is worn, until reaching thechin guard 102, or more precisely itscorresponding support mask 1 for theshock absorbing layer 10. - In this case, the temporary coupling means 6a, 8a, 61 a, 6b, 8b, 61 b of
mask 1 to support theshock absorbing layer 10 of thechin guard 102 are designed to hold saidside padding 106 suitable to engage the user's cheeks. - 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. - After inserting the inner
shock absorbing layer 104 of the user's cranial area within theouter shell 101, the assembly of thesupport mask 1 for ashock absorbing layer 10 of thechin guard 102, according to the particular embodiment of the present invention shown here, first provides that theshock absorbing layer 10 is supported and held onto the mask by holdingmeans tabs layer 10, and thereforemask 1, with thelayer 10, is hooked to thechin guard 102, by way of theprotuberances internal regions chin guard 102; - Finally, the assembly of the helmet provides that the
shock absorbing layers 107 intended to protect the user's cheeks are inserted betweenmask 1 and theshock absorbing layer 104, by way of force fit coupling (forced restraining) achieved between the rear support surfaces, against theinner shell 101, and frontal surfaces, against themask 1, as well as the inner shape of theshell 100, resulting in the final locking of the shock absorbing layers within the helmet. - At this point the constraining of the
padding 105 of the cranial area of theshell 101 to the correspondingshock absorbing layers side padding 106 to thesame 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. - 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 saidpadding 106 and reduces the number of traditional fixing elements, such as elastic clips or Velcro® strips between theshock absorbing layer 107 and the inner walls of thepadding 106. - However if the hooking of the
padding 106 directly to themask 1 also accomplishes the mechanical fixing of saidpadding 106 to themask 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.
