It is understood that elements and characteristics of one embodiment can conveniently be combined or incorporated into other embodiments without further clarifications.

DETAILED DESCRIPTION OF SOME EMBODIMENTS

[0037] We will now refer in detail to the possible embodiments of the invention, of which one or more examples are shown in the attached drawings, by way of a non-limiting illustration. The phraseology and terminology used here is also for the purposes of providing non-limiting examples.

[0038] Referring to FIGS. 1-4, the number 10 indicates a helmet 10 provided with a half chin bar 14, hereafter helmet 10, which satisfies the purposes described above.

[0039] The helmet 10 described here can be used preferably in the field of motor racing, but also in other fields, such as for example motorcycling or the practice of winter sports, such as skiing or snowboarding, or even the practice of paragliding or other sports activities, either civilian or professional, which require the use of protective helmets of the type in question.

[0040] The helmet 10 of the present invention comprises a shell 11 suitable to wrap at least a portion of a user's skull and a padding 12 provided inside the shell 11. During use, a portion of the user's skull is inside the shell 11 and adheres to the padding 12.

[0041] The shell 11 can be provided with a pair of lateral extensions 13a, 13b which at least partly wrap the lateral parts of the user's skull, and which laterally delimit a front aperture of the helmet 10. The shell 11 and the lateral extensions 13a, 13b can be made in a single body and with materials suitable to provie protection to the user in the event of an accident, for example polymer materials, resins, composite materials, carbon fiber, or combinations thereof.

[0042] On the other hand, the padding 12 can be made of materials suitable to improve comfort for the user and to partly absorb shocks and impacts associated with possible accidents.

[0043] The helmet 10 also comprises a half chin bar 14 associated with the shell 11, in particular with one of the lateral extensions 13a, 13b. It is clear that a half chin bar 14 can be mounted indifferently on one or on the other of the lateral extensions 13a, 13b.

[0044] The half chin bar 14 can comprise a covering layer, for example made of polymer material, composite material or carbon fiber, and one or more plastic bodies, which can be conformed to give the half chin bar 14 suitable shapes and sizes. Furthermore, the half chin bar 14 can comprise a microphone and/or bodies or assemblies configured to house and/or serve the microphone, such as for example a filter to reduce background noise during transmission, devices for improving the quality of the audio signal, electric power cables, digital processing devices and more.

[0045] According to some embodiments, the half chin bar 14 is mounted in a cantilevered releasable way and protruding with respect to the shell 11, and extends from a free end 14a positioned, during use, in correspondence with the user's mouth to an attachment end 14b associated with the shell 11.

[0046] According to one aspect of the invention, the half chin bar 14 is connectable/disconnectable to/from the shell 11 by means of an attachment device 16 comprising a coupling portion 20 and a manual drive portion 17. In particular, the manual drive portion 17 is suitable for the complete release of the coupling portion 20 and is accessible from the outside of the shell 11 and/or of the half chin bar 14.

[0047] By virtue of this, it is possible to define an attached configuration of the helmet 10 in which the half chin bar 14 is connected to the shell 11, and a detached configuration of the helmet 10 in which the half chin bar 14 is disconnected from the shell 11. In particular, in the attached configuration the manual drive portion 17 of the attachment device 16 is outside the shell 11.

[0048] By way of a non-limiting example, FIG. 1 shows the helmet 10 in the attached configuration, while FIG. 4 shows the helmet 10 in the detached configuration.

[0049] In some embodiments, the attachment device 16 can comprise a first attachment element 18 suitable to couple to a second attachment element 19 integrated in the shell 11.

[0050] In this specific case, with reference to FIGS. 5-6, the first attachment element 18 and the second attachment element 19 respectively comprise a threaded shank and a threaded hole 20b, which constitute the coupling portion 20.

[0051] Purely by way of example, the second attachment element 19 can be directly laminated into the shell 11 during the manufacturing thereof or, alternatively, inserted therein through deformation.

[0052] Furthermore, the half chin bar 14 can also comprise a passage hole 22 for the first attachment element 18. In particular, in the attached configuration of the helmet 10, the passage hole 22 can be substantially overlapping with the second attachment element 19 and is passed through by the first attachment element 18 which, with the threaded shank 20a, engages the threaded hole 20b of the second attachment element 19.

[0053] According to some embodiments, the first attachment element 18 can comprise a flange 21 disposed substantially opposite to the threaded shank 20a. The flange 21 acts on the half chin bar 14 by pressing it from the outside toward the shell 11 (FIG. 5), stabilizing its connection. In other words, in the attached configuration, the half chin bar 14 is interposed between the flange 21 and the shell 11.

[0054] In accordance with preferred embodiments, the manual drive portion 17 of the attachment device 16 is integral with the first attachment element 18 and is disposed substantially in correspondence with the flange 21.

[0055] This conformation is advantageous since, in the attached configuration of the helmet 10, the manual drive portion 17 is outside the shell 11, making the attachment device 16 immediately accessible. This allows rescuers to remove the half chin bar 14 safely, easily and quickly in the event of an accident, without requiring the helmet 10, and therefore the user's head, to be subjected to significant exertions that could compromise the health of the user.

[0056] In this specific case, the manual drive portion 17 can comprise a gripping flap 23 manually mobile from a passive position to a drive position. In the passive position, the gripping flap 23 is substantially parallel to the flange 21 (FIG. 5), while during use it is substantially perpendicular to the flange 21 (FIG. 6). When the gripping flap 23 is in use, that is, in the drive position, the manual drive portion 17, and therefore the first attachment element 18, can be maneuvered manually without requiring the use of screwdrivers or special tools. This further speeds up any rescue interventions, allowing, for example, to reduce the time required to clear the respiratory tract of the user of the helmet 10.

[0057] In some embodiments, at least one of the lateral extensions 13a, 13b of the shell 11 can comprise an attachment seating 15 suitable to accommodate the attachment end 14b of the half chin bar 14. The attachment seating 15 can be of a shape at least partly mating with that of the attachment end 14b of the half chin bar 14. In particular, the attachment seating 15 can be configured as a hollow made in the shell 11, the perimeter P of which at least partly follows that of the attachment end 14b.

[0058] This conformation is advantageous since it allows to facilitate the centering of the passage hole 22 with the second attachment element 19 during the connection of the half chin bar 14 to the shell 11.

[0059] In other embodiments, the attachment seating 15 can comprise interlocking means 24 suitable to define a same-shape coupling with the attachment end 14b of the half chin bar 14. In fact, the attachment end 14b can comprise one or more protruding parts 25 with a shape mating with the interlocking means 24. In particular, with reference to FIGS. 5-6, the protruding part 25 can be inserted in a suitable hollow 26 comprised in the interlocking means 24.

[0060] This conformation allows to define a preliminary alignment coupling between the half chin bar 14 and the shell 11, facilitating the subsequent insertion of the first attachment element 18 in the passage hole 22 and in the second attachment element 19.

[0061] Once inserted, the first attachment element 18 can be manually maneuvered by means of the manual drive portion 17 and in particular the gripping flap 23, in order to engage the threaded hole 20b of the second attachment element 19 with the threaded shank 20a.

[0062] For example, the first attachment element 18 can be screwed manually by acting through the gripping flap 23. Once the coupling between the first attachment element 18 and the second attachment element 19 has been defined, the gripping flap 23 can be taken from the drive position to the passive position.

[0063] On the other hand, in order to disconnect the half chin bar 14, a user can manually take the gripping flap 23 from the passive position to the drive position, and by means of the same gripping flap 23 manually maneuver the first attachment element 18 in order to disengage it from the second attachment element 19.

[0064] For example, the first attachment element 18 can be manually unscrewed by acting through the gripping flap 23. Once disengaged from the second attachment element 19, the first attachment element 18 can be extracted from the passage hole 22 and the half chin bar 14 can be disconnected from the shell 11.

[0065] The person of skill in the art will easily understand that the half chin bar 14 can be connected/disconnected several times from the shell 11 without compromising the solidity and resistance characteristics of the helmet 10. This allows to replace the half chin bar 14 whenever necessary, for example if slightly damaged or, on each occasion, depending on the use of the helmet 10.

[0066] It is clear that modifications and/or additions of parts may be made to the helmet 10 as described heretofore, without departing from the field and scope of the present invention as defined by the claims.

[0067] In the following claims, the sole purpose of the references in brackets is to facilitate reading: they must not be considered as restrictive factors with regard to the field of protection claimed in the specific claims.
