Definitions

  • the present invention relates to a reinforced visor for full face helmet used by motor racers driving cockpit cars without windshield and more particularly for the dragster drivers.
  • the visors must be manufactured in accordance with the criteria defined by the American standard SNELL SA2010 (SA for Special Applications).
  • SA American standard SNELL SA2010
  • the visors to be able to obtain the SNELL marking must in particular withstand the two main tests provided by said SNELL SA2010 standard. It is an impact resistance test of a lead ball launched at 500 km / h and a propane gas fire test at 790 ° C for 45 seconds with a self-extinguishing time 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 performed by fixing a pin on the helmet, said pin being adapted to cooperate with an orifice arranged on the visor to maintain said visor in the closed position. Unlocking said visor is effected by deformation of the latter.
  • One of the solutions envisaged is to adapt on the existing helmets a visor whose thickness has been increased by passing, for example, from 3 to 6 millimeters in thickness.
  • this solution is not satisfactory because a visor 6 millimeters thick lacks flexibility prohibiting its mechanical locking / unlocking.
  • multiple deformations of this thicker visor related to the manufacturing process (including thermoforming) and mounting on existing helmets, designed for visors 3 millimeters thick introduce optical deformations that disturb the pilot's vision .
  • a visor 6 millimeters thick with a non-constant radius of curvature then behaves like a thick lens and the laws of refraction stated by Snell and Descartes no longer apply as simply.
  • the correction of these optical deformations would require to design a specific helmet adapted to visors 6 millimeters thick.
  • the investments to be implemented would be disproportionate compared to a commercial market for the least confidential.
  • the object of the present invention is therefore to overcome the aforementioned drawbacks and to propose an alternative to the already known visors used on full competition helmets that can be used for drag racing, said alternative being in accordance with the American standard SNELL SA2010 and reinforced to guarantee a sufficient level of protection for the pilots of said draggers. .
  • the reinforced visor according to the invention therefore has fire, impact and dust resistance higher than those provided by said SNELL SA2010 standard.
  • the reinforced visor has all the advantages of a thicker visor without having the disadvantages thereof, in particular being able to be fixed on the existing full-face helmets complying with the SNELL SA2010 standard.
  • a visor reinforced with an integral helmet of drag racing pilots said reinforced visor being adapted to be detachably secured to said integral helmet provided with an opening defining the pilot's field of vision.
  • the secondary visor is of smaller dimensions than those of the main visor on which it is fixed, said secondary visor having at least the same dimensions as the opening of the integral helmet.
  • the main visor comprises at least two first orifices allowing its detachable attachment and rotation relative to the integral helmet, two lights for limiting its angular deflection, and at least two second holes for the mechanical locking of said main visor on said integral helmet, the first and second ports and the two lights being located outside the area of the main visor covered by the secondary visor.
  • the main visor is preferably tinted or not and the secondary visor is untinted.
  • the main and secondary visors are each 3 millimeters thick and are made of polycarbonate.
  • the reinforced visor comprises fixing members, such as metal mechanical fasteners, for fixing the secondary visor on the main visor.
  • the reinforced visor advantageously comprises a seal disposed between the main and secondary visors.
  • the Figures 1 to 3 represent a reinforced visor 1 designed to be secured in a detachable manner on an integral helmet 2 provided with an opening 3 allowing the vision of the pilot wearing said integral helmet 2 and being able to be completely covered by said reinforced visor 1 in order to protect the face of said driver, said integral helmet 2 being similar to full-face helmets already known.
  • the reinforced visor 1 according to the invention comprises a main visor 4 and a secondary visor 5 fixed on the outer face of said main visor 4 by fasteners 6 so as to form a double shielding screen.
  • outer refers to the face of an element disposed on the outer side of the integral helmet 2 and “inside” the face of an element disposed on the inner side of said integral helmet 2.
  • the main visor 4 is similar to visors already known and is advantageously manufactured from polycarbonate 3 millimeters thick to be able to adapt to the integral helmet 2 which is of the type of full-face helmets conforming to the SNELL SA2010 standard and designed to visors 3 millimeters thick.
  • the main visor 4 is provided with all the orifices necessary for its mounting on said integral helmet 2.
  • the main visor 4 comprises at least two first orifices 7 for detachably securing and rotating relative to the integral helmet.
  • two lights 8 allowing the limitation of its angular deflection
  • two second orifices 9 allowing the mechanical locking of said main visor 4 on said integral helmet 2, said second orifices 9 being able to cooperate with fastening elements (not shown) attached to all full-face helmets existing.
  • the main visor 4 which advantageously has a thickness of 3 millimeters, retains all its flexibility allowing easy mechanical locking.
  • the main visor 4 may be more or less tinted.
  • the main visor 4 allows, on the one hand, to use for its manufacture the same molds as those used to make the known visors in accordance with the SNELL SA2010 standard and, on the other hand, to maintain the same mechanisms of opening, closing and locking put in place on the known integral helmets.
  • the secondary visor 5 which is also preferably made from polycarbonate 3 millimeters thick, is smaller than the main visor 4 to which it is attached. Indeed, the secondary visor 5 has at least the same dimensions as the opening 3 of the full face helmet 2 to ensure the driver a maximum field of vision while ensuring the safety of the driver and minimizing the total mass of the reinforced visor 1 according to the invention.
  • the first and second orifices 7, 9 and the two lights 8 are located outside the area of the main visor 4 covered by the secondary visor 5. This configuration makes it possible to keep the reinforced visor 1, once the visors main 4 and secondary 5 assemblies, flexibility for its recovery and mechanical locking.
  • the secondary visor 5 will preferably be untinted so as not to overshadow the vision of the driver in case of sunshine but also to have only one model of secondary visor 5 and thus limit the number of references commercial.
  • the shade of the reinforced visor 1 will then be obtained only by the hue more or less pronounced of the main visor 4.
  • the reinforced visor 1 according to the invention therefore generates no optical deformation that can disturb the pilot's vision.
  • these fasteners 6 are advantageously metal mechanical fasteners such as for example screws preferably embedded in the secondary visor 5.
  • the reinforced visor 1 makes it easy to adapt at a lower cost to an integral helmet 2 of the type of existing helmets without having to modify the mechanisms of opening, closing and locking. Furthermore, it is understood that this reinforced visor 1 is in accordance with the SNELL SA2010 standard because the main visor 4 is similar to the existing visors complying with said standard, but also that this main visor 4 has, because of the presence of the secondary visor 5, fire resistance, impact and fine particles well above those required by said standard SNELL SA2010 .
  • the reinforced visor 1 according to the invention applies more particularly to full-face helmets for drag pilots, but it can also be used for any type of racing of cockpit cars without windshield.
