Definitions

  • This invention relates to a reinforced visor for full-face helmets used by automobile racers driving cockpit cars without windscreen and more particularly for dragster pilots.
  • visors must be manufactured in accordance with the criteria defined by the American standard SNELL SA2010 (SA for Special Applications). Visors in order to obtain the SNELL marking must in particular resist the two main tests provided for by said standard SNELL SA2010. This entails a test for the resistance to the impact of a lead ball launched at 500 km/h and a test for the resistance to a propane gas fire at 790° C. for 45 seconds with self-extinguishing of 20 seconds.
  • the SNELL SA2010 standard imposes a mechanical locking device of the visor on the helmet and prohibits any friction device.
  • This mechanical locking is conventionally carried out by fixing a pin on the helmet, said pin being able to cooperate with an orifice arranged on the visor in order to maintain said visor in closed position.
  • the unlocking of said visor is carried out by deforming the latter.
  • One of the solutions considered consists in adapting on the existing helmets a visor of which the thickness has been increased by changing, for example, from 3 to 6 millimetres in thickness.
  • this solution is not satisfactory because a visor 6 millimetres thick lacks in flexibility which prohibits it from mechanically locking/unlocking.
  • the multiple deformations of this thicker visor linked to the manufacturing process (in particular thermoforming) and mounting on existing helmets, designed for visors 3 millimetres thick introduce optical deformations which disturb the vision of the pilot.
  • a visor 6 millimetres thick with a radius of curvature that is not constant then acts as a thick lens and the laws of refraction put forth by Snell and Descartes no longer apply as simply as that. Correcting these optical deformations would require designing a specific helmet adapted for visors 6 millimetres thick. However, the investments required would be disproportionate in relation to a commercial market for the least confidential.
  • the purpose of this invention is therefore to overcome the aforementioned disadvantages and to propose an alternative to the already known visors used on full-face competition helmets that can be used for dragster races, said alternative being compliant with the American standard SNELL SA2010 and reinforced in order to guarantee a sufficient level of protection for the pilots of said dragsters.
  • the reinforced visor according to the invention therefore has resistance to fire, impact and dust that is higher than that provided for by said standard SNELL SA2010.
  • the reinforced visor has all of the advantages of a thicker visor without having the disadvantages of it, by being in particular able to be fixed on the existing full-face helmets compliant with the SNELL SA2010 standard.
  • a reinforced visor for full-face helmet intended to be used by dragster pilots is therefore proposed, said reinforced visor being able to be removably attached on a full-face helmet provided with an opening defining the field of vision of the pilot wearing said full-face helmet and being able to be entirely covered by said reinforced visor in order to protect the face of said pilot, said reinforced visor comprising a main visor able to be removably and pivotingly attached on said full-face helmet and a secondary visor fixed on the exterior surface of said main visor.
  • the secondary visor has dimensions that are less than those of the main visor whereon it is fixed, said secondary visor having at least the same dimensions as the opening of the full-face helmet.
  • the main visor comprises at least two first orifices allowing it to be removably attached and rotated in relation to the full-face helmet, two holes allowing its angular displacement to be limited, and at least two second orifices allowing for the mechanical locking of said main visor on said full-face helmet, with the first and second orifices and the two holes being located outside of the zone of the main visor covered by the secondary visor.
  • the main visor is tinted or not and the secondary visor is not tinted.
  • the main and secondary visors are each 3 millimetres thick and are manufactured from polycarbonate.
  • the reinforced visor comprises fastening members, of the mechanical fastening metal member type, in order to fix the secondary visor on the main visor.
  • a seal is arranged between the main and secondary visors.
  • Embodiments of the present invention each have at least one of the above-mentioned aspects, but do not necessarily have all of them.
  • FIG. 1 is a perspective view of a reinforced visor according to the invention
  • FIG. 2 is a detailed perspective view of the reinforced visor of FIG. 1 ;
  • FIG. 3 is a perspective view of a full-face helmet provided with the reinforced visor of FIG. 1 .
  • FIGS. 1 to 3 show a reinforced visor 1 designed to be removably attached on a full-face helmet 2 provided with an opening 3 allowing for the vision of the pilot wearing said full-face helmet 2 and being able to be entirely covered by said reinforced visor 1 in order to protect the face of said pilot, said full-face helmet 2 being similar to already known full-face helmets.
  • the reinforced visor 1 in accordance with the invention comprises a main visor 4 and a secondary visor 5 fixed on the exterior surface of said main visor 4 by fastening members 6 in such a way as to form a double protection shield.
  • exit designates the surface of an element arranged on the exterior side of the full-face helmet 2
  • interior designates the surface of an element arranged on the interior side of said full-face helmet 2 .
  • the main visor 4 is similar to already known visors and is manufactured from polycarbonate 3 millimetres thick in order to be able to adapt to the full-face helmet 2 which is of the type of known full-face helmets compliant with the SNELL SA2010 standard and designed for visors 3 millimetres thick. Furthermore, the main visor 4 is provided with all of the orifices required for mounting in on said full-face helmet 2 . As such, the main visor 4 comprises at least two first orifices 7 allowing it to be removably attached and rotated in relation to the full-face helmet 2 , two holes 8 making it possible to limit its angular displacement, two second orifices 9 allowing for the mechanical locking of said main visor 4 on said full-face helmet 2 .
  • the main visor 4 which has a thickness of 3 millimetres, retains all of its flexibility allowing for easy mechanical locking. Finally, according to the rate of sunshine, the main visor 4 can be more or less tinted. Carried out as such, the main visor 4 makes it possible, on the one hand, to use for its manufacture the same moulds as those used to manufacture known visors compliant with the SNELL SA2010 standard and, on the other hand, to retain the same mechanisms for opening, closing and locking implemented on the known full-face helmets.
  • the secondary visor 5 which, according to one embodiment is also manufactured using polycarbonate 3 millimetres thick, is of dimensions that are less than the main visor 4 whereon it is fixed. Indeed, the secondary visor 5 has at least the same dimensions as the opening 3 of the full-face helmet 2 in order to guarantee the pilot with a maximum field of vision which still guaranteeing the safety of the pilot and minimising the total mass of the reinforced visor 1 according to the invention.
  • the first and second orifices 7 , 9 and the two holes 8 are located outside of the zone of the main visor 4 covered by the secondary visor 5 . This configuration makes it possible to retain for the reinforced visor 1 , once the main 4 and secondary 5 visors are assembled, a flexibility allowing it to be raised and mechanically locked.
  • the secondary visor 5 shall, according to one embodiment, not be tinted in order to not excessively mask the vision of the pilot in the event of sunlight but also in order to have only a single secondary visor 5 model and as such limit the number of commercial references.
  • the tint of the reinforced visor 1 will then be obtained only by the more or less pronounced tint of the main visor 4 .
  • the main 4 and secondary 5 visors which are carried out using polycarbonate 3 millimetres thick, are perfectly adapted without excessive deformation to the full-face helmet 2 designed for a simple visor carried out using this same material.
  • the reinforced visor 1 according to the invention therefore does not generate any optical deformation that can disturb the vision of the pilot.
  • the secondary visor 5 In order to constitute the reinforced visor 1 , the secondary visor 5 must therefore be assembled on the exterior surface of the main visor 4 with fastening members 6 .
  • these fastening members 6 are mechanical fastening metal members such as for example screws embedded in the secondary visor 5 .
  • the reinforced visor 1 makes it possible to easily be adapted at least cost on a full-face helmet 2 of the type of existing helmets without having to modify the mechanisms for opening, closing and locking.
  • this reinforced visor 1 is compliant with the SNELL SA2010 standard because the main visor 4 is similar to existing visors that satisfy said standard, but also that this main visor 4 has, due to the presence of the secondary visor 5 , resistance to fire, impact and fine particles that are much higher than those required by said standard SNELL SA2010.
  • the reinforced visor 1 according to the invention is applied more particularly to the full-face helmets of dragster pilots, but it can also be used for any type of race of cockpit cars without a windscreen.
