Abstract

A method for decorating and reinforcing a high strength safety helmet comprises the steps of providing a helmet cap by layering in a mold a plurality of high strength braided fiber layers, preferably made of carbon and Kevlar fibers, suitably impregnated by resins, providing a thermoplastic material over-cap element and applying said over-cap element to the fiber cap. <IMAGE>

Description

    BACKGROUND OF THE INVENTION
  • The present invention relates to a method for decorating and reinforcing a safety helmet of high strength. According to a further aspect thereof, the invention also relates to the safety helmet made by the method.
  • As is known, safety or protective helmets of high strength are conventionally made by using a helmet cap which is produced by overlapping or layering onto one another in a mold a plurality of carbon or Kevlar fiber layers, as suitable impregnated by resins.
  • In a case in which the helmet cap is made by combining carbon and Kevlar fibers, the outer surface of said helmet will have a "braided" aspect.
  • Such a braided aspect through the overall outer surface of the protective helmet may be scarcely pleasant from a mere economic standpoint and, accordingly, the fiber helmets are usually painted by a concealing paint for concealing the helmet cap construction.
  • The document US-A-4 472 472 discloses a method for decorating and reinforcing a helmet according to the preamble of claim 1.
    • SUMMARY OF THE INVENTION
  • Accordingly, the aim of the present invention is to provide such a method allowing to make a safety or protective helmet, of high strength, and having very good aesthetic characteristics.
  • Within the scope of the above mentioned aim, a main object of the present invention is to provide such a method which can also be carried out by using already existing systems and materials, as conventionally used for making prior protective or safety helmets.
  • Yet another object of the present invention is to provide such a method allowing to make a protective helmet having all the required safety and functionality properties.
  • Yet another object of the present invention is to provide such a method which is very flexible and allows to make protective helmets having different and differentiated finishing features, according to requirements.
  • According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a method for decorating and reinforcing a high strength protective or safety helmet, according to claim 1.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • Further characteristics and advantages of the present invention will become more apparent hereinafter from the following detailed disclosure of a preferred, though not exclusive, embodiment of the invention, which is illustrated, by way of an indicative, but not limitative, example, in the accompanying drawings, where:
  • Figure 1 is an exploded perspective view of a protective helmet cap and related overcap, as obtained by the method according to the invention;
  • Figure 2 is a front perspective view of the protective or safety helmet made by the method;
    and
  • Figure 3 is a top perspective view of the protective or safety helmet made by the method.
    • DESCRIPTION OF THE PREFERRED EMBODIMENT
  • With reference to the number references of the above mentioned figures, the safety or protective helmet, according to the present invention, which has been generally indicated by the reference number 1, comprises a helmet cap 2, made by layering, or overlapping, in a mold, a plurality of layers of high strength fibers, preferably carbon and Kevlar fibers, as suitably impregnated by resins.
  • In this connection it should be pointed out that the helmet cap 2 can be also made of boron, glass, polypropylene fibers, as suitably layered by resins.
  • According to the invention, to the helmet cap 2 an overcap 3, of a thermoplastic material, such as polycarbonate, or any other suitable thermoplastic materials is applied.
  • Advantageously, the overcap 3 comprises open portions 4, thereby the reinforcement function of the overcap will be provided only at given regions, while leaving other regions of the cap 2 exposed to the view.
  • The colors, patterns and materials of the overcap 3 would be so designed as to fit the aspect and color of the helmet cap 2 of high strength braided fibers.
  • The protective helmet 1 will be finished by including therein the conventional elements constituting the modern safety or protective helmet, such as an inner shell or liner of polystyrene, several inner paddings and coatings, according to the specific requirements.
  • The figures show a so-called "jet" type of protective or safety helmet.
  • It should be apparent that the method according to the invention can be advantageously applied to any desired type of protective helmets, in particular also to the so-called "integral" or crash helmets.
  • It has been found that the invention fully achieves the intended aim and objects.
  • In fact, the invention provides a method for making a high strength protective or safety helmet having very good aesthetic features.
  • Thus, the method according to the invention achieves two important objects: at first, the method allows to further reinforce or stiffen the fiber helmet cap, which already has per se a comparatively high strength and, moreover, it allows to provide very good aesthetic features to the helmet, while leaving the technologically advanced construction of the helmet to be easily seen.
  • A further advantage of the method according to the present invention is that the overcap can be used for applying fittings such as rivets or support elements for visors, and so on, without notching the fiber helmet cap and, accordingly, without reducing the efficient protection provided by this material.
  • In practicing the invention, the used materials, as well as the contingent size and shapes, can be any, depending on requirements and the status of the art.
