Definitions

  • the present invention relates to an integral or "jet" type of safety helmet for motorcyclists, motorists, sports drivers, including an improved visor.
  • Safety or crash helmets for motorcyclists, motorists, and sports drivers are already known. These prior helmets generally comprise a hollow body, having a substantially cup or cap shape, having a bottom opening for allowing the helmet to be fitted to the user as well as a front vision window.
  • a clear material visor which is pivoted to the cup body of the helmet at two side opposite regions thereof, so that the visor can be lowered or raised depending on the user requirements.
  • the mentioned crash or integral helmets comprise moreover a chin supporting portion arranged at the bottom of the window, whereas in the so-called "jet" helmets, the windows merges with the bottom opening of the cup body of the helmet.
  • the visor of prior helmets is contoured and curved with the same curving raise as the helmet cup body in order to allow the visor to perfectly adhere to the helmet body in the lowered condition of said visor, to prevent air and water from penetrating the helmet.
  • the visor will be flush with the helmet body at the bottom thereof, whereas said visor will not be flush at the top of the helmet since it would not be possible to properly easily open the visor.
  • connection of the visor to the helmet body is conventionally performed by a complex and expensive locking devices projecting from the cup contour and usually comprising pawl elements provided with a snap type of movement.
  • This coupling of the visor to the helmet body causes several drawbacks, such as a not perfect sealing with respect to a possible penetration of air and water, noises due to an aerodynamic turbulence effect, as well as a difficult operation of the visor in its opening and closing movements by the user.
  • prior visors being made of an impact resistant synthetic material are susceptible to be easily scratched thereby reducing the clearness or transparency properties of the visor.
  • prior visors are susceptible to be easily deformed and, accordingly, they must be operated with care by an user during the opening movement which movement, moreover, is frequently difficult to be performed.
  • the aim of the present invention is to overcome the above mentioned drawbacks by providing a safety helmet including a visor which, in the closing condition thereof, is perfectly adhering to the helmet body and which can be operated in a very simple and easy manner by the user.
  • a main object of the present invention is to provide such a helmet-visor assembly which prevents air and water from penetrating the helmet body and which does not generate any aerodynamic noises even at a high driving speed.
  • Another object of the present invention is to provide such a helmet in which the visor does not interfere against the helmet body during the opening and/or closing of said visor, thereby providing an easier movement of the visor as well as a longer duration thereof.
  • Yet another object of the present invention is to provide such a helmet-visor assembly which has very good optical properties and which, in the case of impacts, does not damage the user.
  • the helmet according to the present invention which has been generally indicated by the reference number 1, comprises a hollow cup body 2, which is open at the bottom thereof, and which is provided, on the front thereof, with a window 3.
  • a visor 4 is arranged, said visor being connected, near the top edge portion thereof, to a supporting element 5 extending on the top of the visor 4 at a central region of the front top side of the body 2.
  • the supporting element 5 is articulated to the body 2 at a top region thereof recessed with respect to said visor 4 and being adapted to swing, about a pivot axis thereof, which axis is substantially perpendicular to the symmetry plane of the body 2 in order to allow said visor 4 to be opened or closed with respect to said window 3.
  • the outer surface of the supporting element 5 has preferably the same curved profile as that of the body 2 at the region thereof in which it is arranged and, on the bottom of the supporting element 5, in said body 2, a housing 6 is defined so that, with the visor in its closing condition, the supporting element 5 will not provide any interruptions through the outer profile or contour of the body 2.
  • the edge of the window 3 is advantageously recessed by a recessing amount corresponding to the thickness of the visor 4 so that, with the visor 4 being closed, said visor 4 will perfectly adhere to the edge of the window 3, without providing any interruptions with respect to the profile of the body 2.
  • the supporting element 5 is moreover provided with locking means for locking the visor 4 in its closing position, said locking means comprising a tooth element 7 mounted on the supporting element 5 and engaging with an abutment 8 defined by the front edge of the housing 6.
  • the tooth element 7 is rigid with a slide 9 which is slidably mounted on said supporting element 5 and which projects, by a portion 9a thereof, on the outer side of the latter so that to be easily operated by an user.
  • the slide 9, in particular, is biassed by a spring 10 which resists against the displacement of the slide 9 in the disengagement direction of the tooth element 7 from the abutment 8.
  • Both the tooth element 7 and abutment can be provided with a lead-in beveled portion so as to allow the tooth element 7 to be snap engaged with the abutment 8 by simply pressing the supporting element 5 toward the body 2.
  • the supporting element 5 is articulated, by a middle portion thereof, to an end portion of an arm 11 which is connected, at the other end portion thereof, to the bottom of the housing 6 so as to define or limit the opening angle of the visor 4.
  • the arm 11 is pivoted, with the top end portion thereof, to the supporting element 5 and, with the bottom end portion thereof it is engaged with means for restraining the supporting element 5 and accordingly the visor 4 at middle positions with respect to the positions corresponding to the visor opening and closing position.
  • These restraining means comprise a pair of blocks 12a and 12b which are coupled to the bottom of the housing 6 and each of which defines a path 13a and 13b for a peg 14a, 14b of the bottom end of the arm 11.
  • the path 13a, 13b comprises an engagement portion 15a, l5b which is substantially smooth and therewith the peg 14a, 14b engages as the visor 4 is closed, and a further stepped portion or return portion 16a, 16b provided with steps which define stop regions for the peg 14a, 14b so as to lock the visor 4 at partial-opening positions during the swinging closing movement thereof.
  • a resilient leg 17 extends from the bottom of the housing 6, said leg operating, by an upwardly directed force, on the arm 11 at the end of the visor opening movement in order to cause the pegs 14a and 14b to pass through the return portion 16a and 16b during the subsequent visor closing movement.
  • the visor 4 is connected to the front side of the supporting element 5 at a recessed portion 18 allowing to hold the continuity of the contour of the body also in this region.
  • the visor 4 is provided, at the bottom end portion thereof, with side tooth elements 19 which, as the visor 4 is closed, will be pressure engaged in seats 20 correspondingly provided on the recessed edge of the window 3, thereby stabilizing the visor in this closing position thereof.
  • the visor can be made of a synthetic or resinous material, such as, for example, of polycarbonate, or it can also be made of a safety glass material, of the laminated type, i.e. formed by two or more glass layer having a like shape and pattern, and overlapped onto one another so as to provide a substantially single-piece element which, if broken, would not present damaging problems for the user.

  • a safety glass material of the laminated type, i.e. formed by two or more glass layer having a like shape and pattern, and overlapped onto one another so as to provide a substantially single-piece element which, if broken, would not present damaging problems for the user.
  • the user of the helmet according to the present invention will be self-evident from the above disclosure and, in particular, it should be apparent the operation mode of an user who, by operating by a single hand the slide 9 and the supporting element 5 or the visor 4, will open the visor 4 by causing it to swing about the pivot axis by which the supporting element 5 is pivoted to the body 2.
  • the user can hold the visor 4 in a fully open condition thereof, or in a partially open condition, by causing, during the visor closing movement, the pegs 14a and 14b to engage with the steps of the return portion 16a and 16b as above disclosed.
  • a visor-helmet assembly has been provided, the visor of which can be easily opened by a single hand, without causing any dangers for the user during this operation.
  • the specifically designed visor supporting mechanism will provide an optimum sealing of the visor, while providing a continuous helmet contour, without any noises during the use of the helmet.
