  • 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 protecting helmet for example of the type used in the motorcycling field and in particular with vehicles devoid of a passenger compartment
  • 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.
  • EP 3 132 702 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.
  • 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 elastic countering members have a body 131a constrained to a spring 131b.
  • the body 131a is thus movable, and its movement is countered by the spring 131b.
  • the spring 131b pushes the elastic countering members to a "closed" position of the seat 130, i.e. a position that does not allow the pin to be inserted into or to come out of the seat 130 without displacing the elastic countering members 131.
  • 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 S1 (as shown in particular in figures 7a - 7f ) typically facing the outside of the helmet (i.e. not facing the shell 2).
  • the pin 41 slides along the surface S1 of each countering member 131, causing the separation thereof and countering the action of the spring 131b.
  • the surface S1 is typically arranged on the body 131a of the elastic countering members 131.
  • the pin 41 has a flange 41a, or anyhow a protrusion or portion adapted to cooperate with the countering members 131.

  • 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 comprises protrusions 16d 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 16d come into contact with the lower part of the flange 41a 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 16c, or by a similar elastic device.
  • the unlocking device 16 is preferably placed between the body 13 and the lid 14. This way, when the unlocking member 16 is not operated, it automatically stays positioned underneath the lid 14 and its protrusions 16d do not obstruct the possible entry of the pin 41 of the visor into the seat 12.
