Definitions
- the present invention concerns a protecting helmet, for example of the type used in the motorcycling field and in particular with vehicles devoid of a passenger compartment, comprising, in addition to a liner intended to accommodate the user's head and at least one inner shell made of a shock-absorbing material, such as expanded polystyrene, at least one rigid outer shell defining a front opening for the user's face, as well as a visor that can be raised and lowered with respect to such front opening, thanks to a respective mechanism.

- a liner intended to accommodate the user's head
- at least one inner shell made of a shock-absorbing material, such as expanded polystyrene
- at least one rigid outer shell defining a front opening for the user's face, as well as a visor that can be raised and lowered with respect to such front opening, thanks to a respective mechanism.
- the present invention concerns a protecting helmet provided with a rigid outer shell, for example made of composite material or polycarbonate or yet of another appropriate thermoplastic material, and at least one protective visor normally made of transparent polycarbonate and constrained to the outer shell by means of a relative raising/lowering mechanism which makes it at least rotatable between a lowered position intercepting, at least partially, the front opening of the helmet and a raised position completely disengaged from the latter, and which allows to reversibly constrain the visor of the helmet.
- a relative raising/lowering mechanism which makes it at least rotatable between a lowered position intercepting, at least partially, the front opening of the helmet and a raised position completely disengaged from the latter, and which allows to reversibly constrain the visor of the helmet.
- the protective visor When the protective visor is completely lowered, it is in proximity of the outer shell and adheres to the gaskets, if present, or anyhow to the sides of the frame delimiting the front opening; when the visor is raised in an intermediate position intercepting, partially, the front opening, the distance between the visor and the gaskets, or between the visor and the sides of the front opening, allows an adequate air flow inside the helmet, whereas when the visor is completely raised, it remains in close proximity of the outer shell and reduces overall dimensions and incidence surface with the air flow that strikes it when the vehicle is in motion.
- a similar raising/lowering mechanism can further allow the visor to be arranged flush with the ends of the outer shell surrounding the aforesaid front opening when it is in its completely lowered position and to simultaneously be easily raised by the user thanks to the translation of the protective visor itself away from the front opening, allowed by such raising/lowering mechanism.
- the protective visor of the helmet is to be understood as being in its completely lowered position when it completely, or almost completely, covers the aforesaid front opening of the helmet and as being in its completely raised position when it does not or almost does not interfere at all with such front opening.
- An object of the present invention is to provide a protecting helmet provided with a raising/lowering mechanism of the protective visor which allows to move the protective visor in an effective and structurally non-complex manner.
- Another object of the present invention is to provide a protecting helmet having a raising/lowering mechanism of the protective visor which allows the user to easily assemble and disassemble the protective visor from the helmet.
- a further object of the present invention is to make a protecting helmet which allows to effectively manage the raising and lowering of the respective protective visor by means of a raising/lowering mechanism that can easily be implemented on the helmet itself.
- a protecting helmet comprises an inner shock-absorbing shell and a rigid outer shell which define a front opening for the user's face, as well as a protective visor at least rotatable between a lowered position intercepting, at least partially, the front opening and a raised position disengaged from the front opening.

- the base member comprises a seat adapted to reversibly accommodate the fastening pin, and the mechanism comprises at least a first and a second magnetic-coupling members.
- the first magnetic-coupling member is constrained to, or made in a single piece with, the fastening pin, whereas the second magnetic-coupling member is constrained to, or made in a single piece with, the base member.
- a so-made raising/lowering mechanism is not complex to make and is thus simple and economic to produce. Moreover, during the assembly step of the visor to the helmet, the two magnetic-coupling members attract each other such as to guide the assembly of the visor on the helmet.
- the user brings the visor closer to the helmet, which is attracted in the operative position by the interaction between the magnetic-coupling members.
- the user thus does not have to carry out complex operations to center the visor on the helmet.
- the present solution thus provides a mechanism that allows a simple reversible coupling of the visor on the helmet.
- both the first and second magnetic-coupling members are magnets.
- the embodiment which provides a magnet and a respective member made of ferromagnetic material, or anyhow of a material adapted to be attracted by a magnet is not to be excluded.
- the base member comprises a body and a lid constrained to the body.
- the base member comprises an unlocking device adapted to release the fastening pin from the seat.
- an unlocking device adapted to release the fastening pin from the seat.
- the unlocking device is translationally movable within the base member.
- the unlocking device comprises a slot interposed between the first and the second magnetic-coupling members.
- the seat of the base member comprises at least one elastic countering member. This allows to carry out a reversible coupling between the helmet and visor in a simple manner.
- the mobile member comprises a toothed portion adapted to cooperate with one or more protuberances of the visor. This allows to define intermediate opening positions of the visor.
- the base member comprises a housing portion made in the outer shell or integrally constrained to the outer shell, wherein the body is constrained, preferably rotatably, to the housing portion. This provides a further degree of freedom to the visor.
- the unlocking device comprises at least one protuberance adapted to move and/or deform the at least one elastic countering member.
- the elastic countering member comprises a body coupled to a spring.
- the elastic countering member comprises a tilted surface adapted to cooperate with the fastening pin, so that a translation of the fastening pin towards the elastic countering member causes a movement and/or deformation of the elastic countering member to allow the fastening pin to be inserted into the seat.
- the elastic countering member has a coupling surface adapted to cooperate with the fastening pin, so that a translation of the fastening pin away from the seat is hampered, and is preferably substantially prevented, by the cooperation between the fastening pin and the coupling surface when the fastening pin is placed within the seat.
- “Substantially prevented” means that the removal of the visor from the helmet is only possible by applying a considerable force to the visor, possibly causing the deformation or breakage of the helmet, i.e. that it is not possible with a normal helmet use.

- the elastic countering members 131 are shaped so that, when they come into contact with the pin 41 , they allow (i.e. do not oppose, or oppose with little resistance) the pin 41 to move towards the shell 2 and the pin 41 entering the seat 130 . Moreover, the elastic countering members 131 are shaped so that to resist a moving away movement between the pin 41 and the shell 2 if the pin is inside the seat 130 .
- the elastic countering members 131 (hereinafter also “countering members”) are flared, or anyhow provided with a tilted surface S 1 (as shown in particular in FIGS. 7 a -7 f ) typically facing the outside of the helmet (i.e. not facing the shell 2 ).
- the contact between the pin 41 and the elastic countering members 131 causes the elastic countering members to move away.
- the pin 41 slides along the surface S 1 of each countering member 131 , causing the separation thereof and countering the action of the spring 131 b.

- a first surface (similar to the tilted surface S 1 ) could be deformed by the movement of the pin 41 towards the seat 130 , favoring the entry thereof.
- a second surface (similar to the coupling surface) could instead be coupled to the pin 41 in a substantially non-deformable manner, when the latter is inside the seat 130 , so that to counter its coming out.
- the base member 12 comprises an unlocking device 16 designed to allow the release of the pin 41 from the seat 130 .
- the unlocking device 16 is movable so that its movement operates onto the seat 130 (and in particular on the elastic countering members 131 ), so that the pin 41 can be released from the seat 130 .
- the unlocking device 16 is preferably at least translatable with respect to the shell 2 .
- the unlocking device 16 comprises a handle 16 b, or similar member, that allows a user to grasp and operate the unlocking device 16 .

- the unlocking device 16 comprises protrusions 16 d adapted to favor the movement of the pin 41 in a direction axial to the pin itself. In particular, after the pin 41 has been released from the countering members 131 , the protrusions 16 d come into contact with the lower part of the flange 41 a that is on the pin 41 .
- the movement of the unlocking device 16 in the direction that allows to release the pin 41 from the seat 130 is hampered by a spring 16 c, or by a similar elastic device.
- the unlocking device 16 is preferably placed between the body 13 and the lid 14 .

- the hooking pin 4 c thus couples with the guide 151 so that a part thereof (typically the short side of the “L”) at least partially enters the groove 151 a, as schematically shown in FIG. 6 b .
- the coupling between the hooking pin 4 c and the groove 151 a of the guide 151 contributes in preventing an accidental detachment between the visor 4 and the shell 2 .

- the groove 151 a can have hollows adapted to define predetermined positions for the hooking pin 4 c (and thus for the visor). Such positions typically have certain stability, such as small forces are not sufficient to move the hooking pin 4 c out of one of the hollows.
- the pin 41 can be integrally constrained to the visor 4 , for example by inserting it into a respective opening 4 a of the visor 4 . Moreover, the pin 41 is configured to cooperate with the seat 130 so that to selectively allow to constrain and release the visor 4 from the shell 2 .

- the pin 41 has a substantially two-dimensional base 41 b from which a hollow cylindrical member 41 c protrudes.
- the flange 41 a is obtained on the outer wall of the cylindrical member 41 c. It should be noted that “flange” means any portion or protrusion protruding sideways from the hollow cylindrical member 41 c.

- the mechanism 10 comprises at least a first and a second magnetic-coupling member 11 a, 11 b.
- at least one of the two magnetic-coupling members 11 a, 11 b is a magnet, whereas the other member can be made of magnetic or ferromagnetic material.
- such members will henceforth also be referred to as “magnetic members,” without excluding that one of such members can actually be made, at least in part, of ferromagnetic material.
- the first magnetic member 11 a is constrained, or made in a single piece, with the fastening pin 41 .
- the first magnetic member 11 a is a magnet inserted inside the cylindrical member 41 c of the pin 41 .
- a portion of the pin 41 could be made of magnetic or ferromagnetic material. Such embodiment falls within the “magnetic member made in a single piece with the pin 41 ” definition.
- a second magnetic member 11 b is constrained to, or made in a single piece with, the base member 12 .
- the second magnetic member 11 b is a magnet constrained to the lid 14 of the base member 12 .
- the magnetic members 11 a, 11 b are arranged so that, when the visor 4 is assembled on the shell 2 , the two magnetic members are sufficiently close to attract each other, so that to counter the removal of the visor 4 from the shell 2 .
- the pin 41 must move and/or deform the countering members 131 in order to be inserted inside the seat 130 .
- the magnetic members are thus preferably shaped and arranged so that, when the pin 41 is arranged in proximity of the seat 130 , the force of attraction between the two magnetic members 11 a, 11 b is greater than the resistance of the countering members 131 .
- the moving of the two magnetic members 11 a, 11 b closer one to the other is sufficient to cause the insertion of the pin 41 into the seat 130 , without requiring further external forces, in particular without requiring the user to push.
- the flange 41 a cooperates with at least one tooth 134 .
- the pin 41 is rotatable with respect to the teeth 134 (or to the single tooth 134 ), so that to define relative positions between the flange 41 a and teeth 134 in which the teeth 134 couple with the flange 41 a and hamper the pin 41 from moving away from the shell 2 , and relative positions in which such movement is not hampered.
- the teeth 134 are integrally constrained to the base member 12 , preferably to the body 13 .
- the flange 41 a has missing portions 41 b, which can be placed at the teeth 134 .
- the teeth 134 are arranged on the base member 12 so that when the pin 41 is moved towards the shell 2 , so that to be inserted into the seat 130 , the teeth 134 are arranged at the missing portions 41 b of the flange 41 a. The movement of the pin 41 is thus not hampered by the presence of the teeth 134 .
- the matching between the teeth 134 and portions 41 b occurs at a position of full opening of the visor 4 .
- the tooth 134 (and in particular the head of the tooth 134 ) is at the flange 41 a.
- the pin 41 is thus hampered from possibly moving away from the seat 2 also by the engagement of the teeth 134 and the flange 41 a of the pin.
- FIGS. 10-12 b Only some members of the helmet 1 are shown in FIGS. 10-12 b . The remaining members are substantially identical to those in the embodiment of FIGS. 1-9 . Minor shape modifications can be made to such members so that to ensure sufficient space to the teeth 134 .
- a visor 4 is initially separated from the shell 2 . Then, the visor is moved towards the shell 2 , so that to bring the pin 41 in the proximity of the respective seat 130 .
- the visor 4 is automatically hooked to the shell 2 .
- the attraction between the two magnetic members in fact allows the pin 41 to enter the seat 130 .
- the attraction between the magnetic members 11 a, 11 b allows the pin 41 to move and/or deform the countering members 131 of the seat 130 .
- FIGS. 7 a -7 c Such situation is shown in FIGS. 7 a -7 c and is further schematized in FIGS. 7 d - 7 f.
- the pin 41 is placed in the proximity of the seat 130 .
- the pin 41 is further moved towards the seat 130 and comes into contact with the countering members 131 so that to move them, separating them.
- the flange 41 a cooperates with the tilted surface 51 of the countering members 131 .
- the pin 41 has definitely entered the seat 130 .
- the flange 41 a has gone beyond the countering members 131 .
- the visor 4 is thus rotatably constrained to the shell 2 .
- the pin 41 can in fact rotate inside the seat 130 . Whenever the visor 4 needs to be released from the shell 2 , the pin 41 must be removed from the seat 130 . Typically, the seat 130 hampers such movement. With reference to the embodiment shown, the pin 41 is in the condition of FIG. 7 c . A possible moving of the visor 4 away from the shell 2 (i.e. a movement towards the right, considering the orientation of FIG. 7 c ), is hampered by the engagement between the flange 41 a and the coupling surface S 2 of the countering members 131 .
- a user thus preferably operates on the unlocking device 16 .
- a user operates on the handle 16 b to push the unlocking device 16 .
- the protuberances 16 a come into contact with the tilted walls 131 c present on the countering members 131 , separating them. Thanks to this, the countering members 131 are sufficiently spaced to allow the removal of the pin 41 from the seat 130 , and thus the separation of the visor 4 from the shell 2 .
- the protrusions 16 d begin to act on the pin 41 , causing the visor 4 to axially move away from the seat 130 , i.e. an ejection thereof from the mechanism 10 .
- the operation on the unlocking device can only be carried out when the visor 4 is in its position of maximum opening.
- the hooking pin 4 c is not restrained by the grooved guide 151 and, consequently, the visor 4 can definitely be moved away from the mechanism 10 of the helmet.

- The present invention concerns a protecting helmet, for example of the type used in the motorcycling field and in particular with vehicles devoid of a passenger compartment, comprising, in addition to a liner intended to accommodate the user's head and at least one inner shell made of a shock-absorbing material, such as expanded polystyrene, at least one rigid outer shell defining a front opening for the user's face, as well as a visor that can be raised and lowered with respect to such front opening, thanks to a respective mechanism.
- More in detail, the present invention concerns a protecting helmet provided with a rigid outer shell, for example made of composite material or polycarbonate or yet of another appropriate thermoplastic material, and at least one protective visor normally made of transparent polycarbonate and constrained to the outer shell by means of a relative raising/lowering mechanism which makes it at least rotatable between a lowered position intercepting, at least partially, the front opening of the helmet and a raised position completely disengaged from the latter, and which allows to reversibly constrain the visor of the helmet.
- In the art, it is known to provide protecting helmets, especially for motorcycling or motor use in general, with a raising/lowering mechanism of the protective visor with respect to the front opening of the helmet which allows the visor to rotate around a given axis. Moreover, such mechanisms can provide intermediate positions for the visor. When the protective visor is completely lowered, it is in proximity of the outer shell and adheres to the gaskets, if present, or anyhow to the sides of the frame delimiting the front opening; when the visor is raised in an intermediate position intercepting, partially, the front opening, the distance between the visor and the gaskets, or between the visor and the sides of the front opening, allows an adequate air flow inside the helmet, whereas when the visor is completely raised, it remains in close proximity of the outer shell and reduces overall dimensions and incidence surface with the air flow that strikes it when the vehicle is in motion.
- Moreover, a similar raising/lowering mechanism can further allow the visor to be arranged flush with the ends of the outer shell surrounding the aforesaid front opening when it is in its completely lowered position and to simultaneously be easily raised by the user thanks to the translation of the protective visor itself away from the front opening, allowed by such raising/lowering mechanism.
- It should be noted that, for simplicity, here and hereinafter, the protective visor of the helmet is to be understood as being in its completely lowered position when it completely, or almost completely, covers the aforesaid front opening of the helmet and as being in its completely raised position when it does not or almost does not interfere at all with such front opening.
- Although effective, the various known structures have a high constructive complexity. As a result, they are difficult and costly to produce.
- Moreover, given the high number of members which must cooperate with each other, it is difficult for the user to assemble and disassemble the visor from the helmet.
- An object of the present invention is to provide a protecting helmet provided with a raising/lowering mechanism of the protective visor which allows to move the protective visor in an effective and structurally non-complex manner.
- Another object of the present invention is to provide a protecting helmet having a raising/lowering mechanism of the protective visor which allows the user to easily assemble and disassemble the protective visor from the helmet.
- A further object of the present invention is to make a protecting helmet which allows to effectively manage the raising and lowering of the respective protective visor by means of a raising/lowering mechanism that can easily be implemented on the helmet itself.
- These and other objects are achieved by the protecting helmet according to embodiments of the present invention, according to one or more of the accompanying claims. In particular, a helmet according to the first independent claim is object of the present invention, whereas preferred aspects are set forth in its successive dependent claims.
- According to an aspect of the present invention, a protecting helmet comprises an inner shock-absorbing shell and a rigid outer shell which define a front opening for the user's face, as well as a protective visor at least rotatable between a lowered position intercepting, at least partially, the front opening and a raised position disengaged from the front opening. The helmet further comprises a raising/lowering mechanism (and of constraint/release) of the protective visor, and the raising/lowering mechanism in turn comprises:
-
- at least one base member, movably or integrally constrained to, or made in a single piece with, the outer shell, arranged in a side position with respect to the front opening;
- at least one fastening pin constrained inside a relative opening of the protective visor.
- The base member comprises a seat adapted to reversibly accommodate the fastening pin, and the mechanism comprises at least a first and a second magnetic-coupling members. The first magnetic-coupling member is constrained to, or made in a single piece with, the fastening pin, whereas the second magnetic-coupling member is constrained to, or made in a single piece with, the base member.
- A so-made raising/lowering mechanism is not complex to make and is thus simple and economic to produce. Moreover, during the assembly step of the visor to the helmet, the two magnetic-coupling members attract each other such as to guide the assembly of the visor on the helmet.
- In particular, during the assembly, the user brings the visor closer to the helmet, which is attracted in the operative position by the interaction between the magnetic-coupling members. The user thus does not have to carry out complex operations to center the visor on the helmet.
- The present solution thus provides a mechanism that allows a simple reversible coupling of the visor on the helmet.
- According to a possible aspect of the invention, both the first and second magnetic-coupling members are magnets. However, the embodiment which provides a magnet and a respective member made of ferromagnetic material, or anyhow of a material adapted to be attracted by a magnet, is not to be excluded.
- According to a possible further aspect of the invention, the base member comprises a body and a lid constrained to the body.
- According to a possible aspect of the invention, the base member comprises an unlocking device adapted to release the fastening pin from the seat. By operating on such device, the user can remove the visor from the helmet in a simple manner.
- According to a possible aspect of the invention, the unlocking device is translationally movable within the base member.
- According to a possible further aspect, the unlocking device comprises a slot interposed between the first and the second magnetic-coupling members.
- Still according to a possible further aspect of the invention, the seat of the base member comprises at least one elastic countering member. This allows to carry out a reversible coupling between the helmet and visor in a simple manner.
- According to a possible further aspect, the mobile member comprises a toothed portion adapted to cooperate with one or more protuberances of the visor. This allows to define intermediate opening positions of the visor.
- According to a possible further aspect, the base member comprises a housing portion made in the outer shell or integrally constrained to the outer shell, wherein the body is constrained, preferably rotatably, to the housing portion. This provides a further degree of freedom to the visor.
- According to a possible aspect, the unlocking device comprises at least one protuberance adapted to move and/or deform the at least one elastic countering member.
- According to a possible aspect, the elastic countering member comprises a body coupled to a spring.
- According to a possible aspect, the elastic countering member comprises a tilted surface adapted to cooperate with the fastening pin, so that a translation of the fastening pin towards the elastic countering member causes a movement and/or deformation of the elastic countering member to allow the fastening pin to be inserted into the seat.
- In other words, when a user couples the visor to the helmet, i.e. brings the fastening pin towards the respective seat, the pin comes into contact with the elastic countering member, which opposes little resistance, thus allowing a user to easily insert the pin in the seat.
- According to a possible aspect, the elastic countering member has a coupling surface adapted to cooperate with the fastening pin, so that a translation of the fastening pin away from the seat is hampered, and is preferably substantially prevented, by the cooperation between the fastening pin and the coupling surface when the fastening pin is placed within the seat.
- “Substantially prevented” means that the removal of the visor from the helmet is only possible by applying a considerable force to the visor, possibly causing the deformation or breakage of the helmet, i.e. that it is not possible with a normal helmet use.

helmet 1 according to the present invention, preferably adapted for use with vehicles devoid of a passenger compartment, such as motorcycles or snowmobiles, according to the known art comprises a rigidouter shell 2, for example made of polycarbonate or ABS (Acrylonitrile Butadiene Styrene), or also of glass fiber, or carbon or aramid fiber (i.e.: Kevlar®), etc. The rigid outer shell 2 (hereinafter also “shell 2”) is typically internally covered by a layer (also denoted by “inner shell,” not shown in the figures) made of a material that is able to absorb any shock, such as expanded polystyrene. A liner, not shown in detail, for example in foam rubber, is typically arranged inside thehelmet 1 to favor the comfort of the user. - At least one
front opening 3 of theprotection helmet 1, which leaves part of the face uncovered, and in particular at least the eyes of the user of thehelmet 1, is defined in theshell 2. Suchfront opening 3 is susceptible to being covered, at least partially, by aprotective visor 4, usually transparent, constrained at least in a rotatable manner to theshell 2 of the helmet itself. - The protective visor 4 (hereinafter also “
visor 4”) is normally made of a polymeric material such as polycarbonate, and is constrained to theouter shell 2 of the protectinghelmet 1 by means of a raising/loweringmechanism 10 of thevisor 4 itself. In particular, the raising/lowering mechanism (for simplicity also named “mechanism 10”) allows theprotective visor 4 to be raised and lowered between a position intercepting, at least partially and preferably completely, thefront opening 3 of thehelmet 1 and a position disengaged, completely or almost completely disengaged, from thisfront opening 3. As is known, the aforesaid intercepting position assumed by theprotective visor 4 coincides with the completely lowered position, whereas the aforesaid disengaged position corresponds to the completely raised position of thevisor 4 itself. - The
mechanism 10 comprises at least onebase member 12, movably or integrally constrained to, or at least partially made in a single piece with, theshell 2. Such mechanism is arranged in a side position with respect to thefront opening 3. - The
base member 12 is typically composed of several components. At least part of such components can be made in a single piece, or anyhow integrally constrained to theshell 2. - In the shown embodiment, the base member comprises a
body 13 constrained to ahousing portion 15 obtained in theshell 2. Thebody 13 is rotatably constrained, with a limited freedom of rotation, with respect to thehousing portion 15. Anelastic return member 132 adjusts the relative rotation between thebody 13 and thehousing portion 15. In a possible embodiment, thebody 13 is rotatably constrained to thehousing portion 15 in a similar manner as the one described in EP 3132702 A1. - A
lid 14 is adapted to cover thebody 13. Thelid 14 is preferably perforated, so that to allow the passage of at least part of a fastening pin 41 (better described below) integrally constrained to thevisor 4. - As mentioned above, the solution shown in the figures is only a possible embodiment of a
helmet 1 according to the present invention. Different variants are possible. By way of example, some possible alternative embodiments are listed hereunder (such list is not to be considered exhaustive). - In a possible variant, the
lid 14 is not present. - In a possible further variant, the
lid 14 is made in a single piece with thebody 13. - In a possible further variant, the
housing portion 15 is a member distinct from theshell 2 and is typically integrally constrained thereto. - In a possible further variant, the
body 13 is integrally constrained to thehousing portion 15. - In a possible further variant, the
body 13 is made in a single piece with theshell 2. - Possible further variants have combinations of the features of the variants described above.
- In general, the
base member 12 is designed to be constrained to theshell 2 and to rotatably and reversibly receive thefastening pin 41. - In order to cooperate with the fastening pin 41 (hereinafter also “pin 41”), better described below, the
base member 12 comprises at least oneseat 130 adapted to reversibly house, or to anyhow be constrained to, thepin 41. In particular, theseat 130 is shaped so that to allow thepin 41 to rotate with respect to the base member, despite being reversibly restrained by it. Typically, such effect is achieved by allowing a sliding between thefastening pin 41 and theseat 130. - Preferably, the
seat 130 has at least one elastic counteringmember 131. In the shown embodiment, there are two elastic counteringmembers 131 arranged facing each other. - “Elastic countering member” is to be understood as a member that is elastically movable and/or elastically deformable (or anyhow elastically yielding).
- In the embodiment shown, the elastic countering
members 131 are spring members. In particular, according to a preferred embodiment, the elastic countering members have abody 131 a constrained to aspring 131 b. Thebody 131 a is thus movable, and its movement is countered by thespring 131 b. Typically, thespring 131 b pushes the elastic countering members to a “closed” position of theseat 130, i.e. a position that does not allow the pin to be inserted into or to come out of theseat 130 without displacing the elastic counteringmembers 131. - Preferably, the elastic countering
members 131 are shaped so that, when they come into contact with thepin 41, they allow (i.e. do not oppose, or oppose with little resistance) thepin 41 to move towards theshell 2 and thepin 41 entering theseat 130. Moreover, the elastic counteringmembers 131 are shaped so that to resist a moving away movement between thepin 41 and theshell 2 if the pin is inside theseat 130. Preferably, for such purpose, the elastic countering members 131 (hereinafter also “countering members”) are flared, or anyhow provided with a tilted surface S1 (as shown in particular inFIGS. 7a-7f ) typically facing the outside of the helmet (i.e. not facing the shell 2). The contact between thepin 41 and the elastic counteringmembers 131, in a direction of thepin 41 moving towards theshell 2, causes the elastic countering members to move away. In particular, in the embodiment shown, thepin 41 slides along the surface S1 of each counteringmember 131, causing the separation thereof and countering the action of thespring 131 b. The surface S1 is typically arranged on thebody 131 a of the elastic counteringmembers 131. - In the shown embodiment, as will be better discussed below, the
pin 41 has aflange 41 a, or anyhow a protrusion or portion adapted to cooperate with the counteringmembers 131. With particular reference toFIGS. 7a-7f , when thepin 41 moves towards the shell, theflange 41 a pushes the tilted surface S1 of the counteringmembers 131 so that to move them away, countering the action of thespring 131 b, to be able to go beyond them. When thepin 41 is inside the seat (as visible inFIG. 7c , and in the schematic view 70, a possible moving away of thepin 41 from the shell 2 (i.e. a movement towards the right, considering the orientation ofFIGS. 7c and 7f ) is hampered by the engagement between the counteringmembers 131 and thepin 41, and in particular between thepin 41 and a coupling surface S2 of the counteringmembers 131. Such coupling surface S2, when coupled to theflange 41 a, is arranged to interfere with theflange 41 a, and is typically arranged substantially parallel to theflange 41 a. - The above description is also applied to elastic countering
members 131 that are elastically deformable, possibly not provided with a spring. In other words, the coupling between thepin 41 and the elastic counteringmember 131 could substantially be a snap-coupling, or anyhow a shape coupling. For example, a first surface (similar to the tilted surface S1) could be deformed by the movement of thepin 41 towards theseat 130, favoring the entry thereof. A second surface (similar to the coupling surface) could instead be coupled to thepin 41 in a substantially non-deformable manner, when the latter is inside theseat 130, so that to counter its coming out. - According to a preferred aspect shown in the figures, the
base member 12 comprises an unlockingdevice 16 designed to allow the release of thepin 41 from theseat 130. - Preferably, the unlocking
device 16 is movable so that its movement operates onto the seat 130 (and in particular on the elastic countering members 131), so that thepin 41 can be released from theseat 130. In particular, the unlockingdevice 16 is preferably at least translatable with respect to theshell 2. - According to a possible aspect, the unlocking
device 16 comprises ahandle 16 b, or similar member, that allows a user to grasp and operate the unlockingdevice 16. - With reference to the embodiment shown in the figures, the unlocking
device 16 preferably comprises at least oneprotuberance 16 a (FIG. 4a ) adapted to cooperate at least with one tilted (or at least partly tilted)surface 131 c (FIG. 5b ) of the counteringmembers 131. Typically, the number ofprotuberances 16 a is equal to the number of counteringmembers 131. In fact, two counteringmembers 131 and twoprotuberances 16 a of the unlockingdevice 16 are shown in the figures. - By moving the unlocking device 16 (downwards with reference to the orientation of the pieces shown in
FIG. 4a ), theprotuberances 16 a couple with tiltedwalls 131 c of the counteringmembers 131, so that to separate them. According to a possible aspect, the unlockingdevice 16 comprisesprotrusions 16 d adapted to favor the movement of thepin 41 in a direction axial to the pin itself. In particular, after thepin 41 has been released from the counteringmembers 131, theprotrusions 16 d come into contact with the lower part of theflange 41 a that is on thepin 41. The obstacle provided by the coupling surfaces S2 of the counteringmembers 131 no longer being present, the coupling between theseprotrusions 16 d and thepin 41 causes an axial translation towards the outside of the visor which is consequently gradually moved away and ejected from theseat 130. - Preferably, the movement of the unlocking
device 16 in the direction that allows to release thepin 41 from theseat 130 is hampered by aspring 16 c, or by a similar elastic device. The unlockingdevice 16 is preferably placed between thebody 13 and thelid 14. This way, when the unlockingmember 16 is not operated, it automatically stays positioned underneath thelid 14 and itsprotrusions 16 d do not obstruct the possible entry of thepin 41 of the visor into theseat 12. - However, there are possible embodiments in which, to release the
pin 41 from theseat 130, it is sufficient to exert a force above a given threshold, so that to move and/or deform the counteringmembers 131. For safety reasons, such force must be sufficiently high, so that to prevent thevisor 4 from being released from theshell 2. In such embodiments, the unlocking device could be absent. - According to a possible embodiment, the
base member 12 comprises atoothed portion 133, adapted to cooperate with one ormore protuberances 4 b of thevisor 4. The coupling between theprotuberances 4 b and thetoothed portion 133 allows to define a stable angular position of thevisor 4 with respect to theshell 2. By operating a force above a given threshold on thevisor 4, it is possible to elastically move and/or deform the toothed portion 133 (by compressing thesprings 133 a for example), so that to allow thevisor 4 to move with respect to the stable position mentioned. - Moreover, preferably, the
base portion 12 is provided with aguide 151 adapted to cooperate with a hookingpin 4 c of thevisor 4. The hookingpin 4 c preferably is, in a side view, substantially “L-shaped,” so that a portion of the hooking pin couples to theguide 151. In particular, theguide 151 has agroove 151 a of variable depth along its length. The hookingpin 4 c can be made in a single piece with the visor, or it can be a member constrained thereto. - The hooking
pin 4 c thus couples with theguide 151 so that a part thereof (typically the short side of the “L”) at least partially enters thegroove 151 a, as schematically shown inFIG. 6b . In such condition, the coupling between the hookingpin 4 c and thegroove 151 a of theguide 151 contributes in preventing an accidental detachment between thevisor 4 and theshell 2. Thegroove 151 a is shaped so that when thevisor 4 is in the position of maximum opening, its height is null, as schematically shown inFIG. 6c . In such condition, the hookingpin 4 c is not restrained by theguide 151. Instead, in other positions of thevisor 4, preferably there is the coupling between the hookingpin 4 c and thegroove 151 a such as to prevent a moving away movement between theshell 2 and thevisor 4. This way, it is only possible to carry out the removal of thevisor 4 from theshell 2 when thevisor 4 is in its position of maximum opening. - According to a possible aspect, the
groove 151 a can have hollows adapted to define predetermined positions for the hookingpin 4 c (and thus for the visor). Such positions typically have certain stability, such as small forces are not sufficient to move the hookingpin 4 c out of one of the hollows. - The
pin 41 can be integrally constrained to thevisor 4, for example by inserting it into arespective opening 4 a of thevisor 4. Moreover, thepin 41 is configured to cooperate with theseat 130 so that to selectively allow to constrain and release thevisor 4 from theshell 2. - As mentioned, in a possible embodiment, the
pin 41 has aflange 41 a adapted for selectively constraining and releasing the pin in a substantially “snap-fit” manner with the counteringmembers 131 of theseat 130. - With reference to the figures, in a possible embodiment, the
pin 41 has a substantially two-dimensional base 41 b from which a hollowcylindrical member 41 c protrudes. Theflange 41 a is obtained on the outer wall of thecylindrical member 41 c. It should be noted that “flange” means any portion or protrusion protruding sideways from the hollowcylindrical member 41 c. - It should be noted that in a possible variant, the
pin 41 could be provided with a groove, inside which a portion of a relevant counteringmember 131 could be coupled, for example by a snap-coupling. - As mentioned, the
mechanism 10 comprises at least a first and a second magnetic-coupling member coupling members - The first
magnetic member 11 a is constrained, or made in a single piece, with thefastening pin 41. In the shown embodiment, the firstmagnetic member 11 a is a magnet inserted inside thecylindrical member 41 c of thepin 41. A portion of thepin 41 could be made of magnetic or ferromagnetic material. Such embodiment falls within the “magnetic member made in a single piece with thepin 41” definition. - A second
magnetic member 11 b is constrained to, or made in a single piece with, thebase member 12. In the shown embodiment, the secondmagnetic member 11 b is a magnet constrained to thelid 14 of thebase member 12. - The
magnetic members visor 4 is assembled on theshell 2, the two magnetic members are sufficiently close to attract each other, so that to counter the removal of thevisor 4 from theshell 2. - In particular, according to a preferred aspect described above, the
pin 41 must move and/or deform the counteringmembers 131 in order to be inserted inside theseat 130. The magnetic members are thus preferably shaped and arranged so that, when thepin 41 is arranged in proximity of theseat 130, the force of attraction between the twomagnetic members members 131. In other words, the moving of the twomagnetic members pin 41 into theseat 130, without requiring further external forces, in particular without requiring the user to push. - In a possible embodiment shown in
FIGS. 10-12 b, theflange 41 a cooperates with at least onetooth 134. Preferably, there are two ormore teeth 134. The following description, for simplicity, discusses the case of twoteeth 134, but it can also be applied to a different number, i.e. greater or lower, ofteeth 134. Thepin 41 is rotatable with respect to the teeth 134 (or to the single tooth 134), so that to define relative positions between theflange 41 a andteeth 134 in which theteeth 134 couple with theflange 41 a and hamper thepin 41 from moving away from theshell 2, and relative positions in which such movement is not hampered. - The
teeth 134 are integrally constrained to thebase member 12, preferably to thebody 13. Theflange 41 a has missingportions 41 b, which can be placed at theteeth 134. In particular, theteeth 134 are arranged on thebase member 12 so that when thepin 41 is moved towards theshell 2, so that to be inserted into theseat 130, theteeth 134 are arranged at the missingportions 41 b of theflange 41 a. The movement of thepin 41 is thus not hampered by the presence of theteeth 134. Typically, the matching between theteeth 134 andportions 41 b occurs at a position of full opening of thevisor 4. Successively, when thepin 41 is inserted into theseat 130 and the visor is at least partially closed, the tooth 134 (and in particular the head of the tooth 134) is at theflange 41 a. Thepin 41 is thus hampered from possibly moving away from theseat 2 also by the engagement of theteeth 134 and theflange 41 a of the pin. - It should be noted that only some members of the
helmet 1 are shown inFIGS. 10-12 b. The remaining members are substantially identical to those in the embodiment ofFIGS. 1-9 . Minor shape modifications can be made to such members so that to ensure sufficient space to theteeth 134. - In use, a
visor 4 is initially separated from theshell 2. Then, the visor is moved towards theshell 2, so that to bring thepin 41 in the proximity of therespective seat 130. - As mentioned above, according to a preferred aspect, thanks to such nearing, the
visor 4 is automatically hooked to theshell 2. The attraction between the two magnetic members in fact allows thepin 41 to enter theseat 130. In particular, with reference to the preferred embodiment described above, the attraction between themagnetic members pin 41 to move and/or deform the counteringmembers 131 of theseat 130. - Such situation is shown in
FIGS. 7a-7c and is further schematized inFIGS. 7d -7 f. InFIGS. 7a and 7d , thepin 41 is placed in the proximity of theseat 130. InFIGS. 7b and 7e , thepin 41 is further moved towards theseat 130 and comes into contact with the counteringmembers 131 so that to move them, separating them. In particular, according to the embodiment shown, theflange 41 a cooperates with the tilted surface 51 of the counteringmembers 131. - In
FIGS. 7c and 7f , thepin 41 has definitely entered theseat 130. In particular, in the embodiment shown, theflange 41 a has gone beyond the counteringmembers 131. Thevisor 4 is thus rotatably constrained to theshell 2. - The
pin 41 can in fact rotate inside theseat 130. Whenever thevisor 4 needs to be released from theshell 2, thepin 41 must be removed from theseat 130. Typically, theseat 130 hampers such movement. With reference to the embodiment shown, thepin 41 is in the condition ofFIG. 7c . A possible moving of thevisor 4 away from the shell 2 (i.e. a movement towards the right, considering the orientation ofFIG. 7c ), is hampered by the engagement between theflange 41 a and the coupling surface S2 of the counteringmembers 131. - It should be noted that the embodiment shown in the figures and herein discussed in detail provides that the countering members are provided with tilted surfaces 51, whereas the side surface of the
pin 41 is substantially parallel to the axis of the pin itself. Alternative and equivalent embodiments provide that also (or only) thepin 41 is equipped with tilted surfaces. It is thus possible to provide alternative and equivalent solutions which implement the kinematic reversals with respect to that which has been shown. - In order to allow the movement of the
pin 41, a user thus preferably operates on the unlockingdevice 16. - In the shown embodiment, a user operates on the
handle 16 b to push the unlockingdevice 16. This way, theprotuberances 16 a come into contact with the tiltedwalls 131 c present on the counteringmembers 131, separating them. Thanks to this, the counteringmembers 131 are sufficiently spaced to allow the removal of thepin 41 from theseat 130, and thus the separation of thevisor 4 from theshell 2. By continuing to exert the thrust on the unlockingdevice 16, theprotrusions 16 d begin to act on thepin 41, causing thevisor 4 to axially move away from theseat 130, i.e. an ejection thereof from themechanism 10. - Moreover, in the shown embodiment, the operation on the unlocking device can only be carried out when the
visor 4 is in its position of maximum opening. In this configuration, the hookingpin 4 c is not restrained by thegrooved guide 151 and, consequently, thevisor 4 can definitely be moved away from themechanism 10 of the helmet. - With reference to the embodiment of
FIGS. 10-12 b, in the closed position, in addition to the members mentioned above, the engagement of theteeth 134 andflange 41 a also hinders the removal of the visor.
