Description
[0001] The present invention relates to a helmet, particularly
protective helmet for work or sports.
[0002] The object of the present invention belongs to the field of
helmets, headpieces and/or similar safety protective headgears
which can be used during the performing of dangerous and risky
activities, such as those carried out in construction sites, mines,
oil platforms, by fire-fighters, by first aid providers, by
mountain climbers or those carried out in any field where it is
necessary to protect the head of the users. The object of the
present invention is also suitable to be applied in the field of
sports helmets, such as for example those intended for cycling,
horse riding, skiing and for any other sports activity requiring
the use of helmets.
[0003] As known, protective helmets for work generally comprise a
structure having at least one convex outer surface and at least one
concave inner surface adapted to receive in engagement the head of
a user.
[0004] The inner surface of the helmet structure is usually
equipped with a protective body made of a material suitable for
shock and impacts absorption, such as polystyrene.
[0005] Generally, the protective bodies of the aforementioned
helmets are made by molding in a single polystyrene monobloc which
has a predetermined density on all parts of the protective
body.
[0006] The protective bodies are usually engaged to the helmet
structure by means of special interlocks so as to be removable if
necessary.
[0007] Although the helmets described above provide for the
removable engagement of the respective protective bodies, the
Applicant has found that they are not free from some drawbacks and
can be improved under various respects, mainly in relation to the
practicality and ease of assembly and disassembly of the protective
bodies with respect to the structure of the helmet, as well as the
adjustment of the positions of the protective bodies with respect
to the structure of the helmet.
[0008] The main object of the present invention is to propose a

[0041] According to an advantageous aspect of the present
invention, the helmet 1 comprises at least a coupling mechanism 6
(FIGS. 2 and 3) operatively interposed between the structure 2 and
the protective body 3 to ensure a removable engagement of the
latter to the structure 2.
[0042] The coupling mechanism 6 comprises at least one coupling
seat 7, preferably made on the protective body and at least one
coupling element 8, preferably arranged on the structure 2 of the
helmet 1, even more preferably protruding from the inner surface 2b
of the latter.
[0043] The coupling element 8 is arranged to engage the coupling
seat 7 in such a way that the protective body 3 can be positioned
according to at least two different positions, preferably a
plurality of different positions, with respect to the structure 2
of the helmet 1.
[0044] In detail, the coupling seat 7 and the coupling element 8 of
the coupling mechanism 6 are configured so as to allow adjustment,
in height, of the protective body 3 with respect to the structure 2
of the helmet 1.
[0045] As visible in the enlargement of FIG. 3, the coupling seat 7
of the coupling mechanism 6 comprises at least one cavity 7a made
in the protective body 3 and at least one fixing button 7b which
can be placed inside the cavity 7a of the coupling seat 7,
preferably fixable to the cavity 7a of the coupling seat 7 in such
a way as to remain inside the latter according to a predetermined
position.
[0046] The fixing button 7b has a substantially truncated-cone
shaped frame on which at least one latching slot 7c (FIGS. 3 and 5)
is obtained, preferably at least partly elastically deformable, due
to an engagement, preferably by snap or by interference, of the
coupling element 8 of the coupling mechanism 6.
[0047] Advantageously, the coupling element 8 comprises at least an
engagement pin 8a provided with two or more surface projections
8b.
[0048] Each surface projection 8b of the engagement pin 8a
determines a relative position, preferably, in height, between the
protective body 3 and the helmet 1 structure 2.
[0049] As visible in FIGS. 1, 2, 4 and 5, the cavity 7a of the
coupling seat 7 is realized on the base element 4 of the protective
body 3, preferably on the inner annular portion 4h of the base
element 4.
[0050] The cavity 7a of the coupling seat 7 faces toward the same
side as the housing cavity 4h of the base element 4, i.e. on the
opposite side with respect to the concave surface 4a of the
latter.
[0051] As visible in FIGS. 1, 2, 4 and 5, the coupling mechanism 6
comprises at least two coupling seats 7 aligned along a
longitudinal axis of the protective body 3, disposed respectively
in a front portion and in a rear portion of the latter.
[0052] Each coupling seat 7 of the coupling mechanism 6 is formed
near the housing cavity 4b of the base element 4 of the protective
body 3.
[0053] It should be noted that the coupling mechanism 6 described
above can be applied both to protective bodies 3 provided with two
or more components as shown in FIGS. 1, 2, 4 and 5, or to monobloc
protective bodies.
[0054] The helmet according to the present invention solves the
problems observed in the known technique and achieves important
advantages.
[0055] First of all, through the coupling mechanism the engagement
between the protective body and the helmet structure has excellent
stability.
[0056] It should also be noted that the coupling mechanism allows
the assembly or disassembly of the protective body on the helmet
structure in an easy, simple and rapid way.
[0057] Furthermore, the coupling mechanism between the protective
body and the helmet structure allows for an easy and effortless
adjustment of the height of the protective body, giving the helmet
itself greater adaptability to the size of the user's head.
Depending on the size of the user's head, the height adjustment of
the protective body prevents the structure of the helmet from
reducing the visibility of the user wearing the helmet.
