Definitions

  • the present invention relates to a protective helmet with a honeycomb structure, in particular for users of two-wheeled vehicles.
  • Helmets of this type generally consist of an outer shell, an internal shock absorbing device, a comfort material allowing the helmet to be adapted to different head sizes and a retention device ensuring the helmet held on the head. It is understood that the assembly constitutes a relatively complex product and, depending on the sophistication of its components, expensive. In this case, the role of the cap is limited to avoid the penetration of blunt obstacles and to allow a distribution of impact forces. The shock absorption itself is provided by the internal device and the cap participates only a little.
  • the present invention relates to a protective helmet provided with a cap playing a damping role, which makes it possible to simplify its structure, compared to that of its previous counterparts, and considerably improve user safety compared to helmets of the type "banana”.
  • the protective helmet according to the present invention essentially consists of a thermoformed cap, held in place by any usual conventional means, such as for example a chinstrap system not shown for the convenience of the drawing.
  • the surface of the cap 1 is shaped so as to constitute a large number of cells 2, the ends of which alone can be in contact with the skull of the user. Between these contact zones of limited total area, air can circulate continuously, allowing the cooling of the head. This effect can be further increased by arranging holes in different places of the cap 1, in particular on the surface of the cells 2.
  • the latter constitute energy absorbers, because they are deformable by buckling under the action of an impact.
  • the shock-absorbing cap according to the invention can take a large number of forms, depending on the parameter considered.
  • the cells are replaced by ribs 60, having the same function.
  • the circulation of air in the ribs 60 is particularly favored, which allows good cooling and constant ventilation of the head, and thus contributes to the comfort of a cyclist providing significant effort and continued.
  • the shape of the cell 70 is specially studied in its aerodynamic aspect, so as to minimize its appearance as an air trap, by consequently promoting the good flow of the air streams 71.
  • the caps 1 can be produced in various ways, either by injection molding or by thermoforming from thermoplastic materials such as polyolefins (high and low density polyethylene, polypropylene and copolymers), acrylonitrile - butadiene - styrene copolymers, polyamides , polycarbonates, polyurethane, ethylene - vinyl acetate copolymers. P.V.C. etc., or produced by vulcanization of compression or transfer molded elastomers or by crosslinking of cast products such as polyurethanes, etc.
  • the stamps forming cells can also be produced by extrusion blow molding, rotational molding or gelation, for example of low density polyethylene.
  • the honeycomb ribbed cap in one operation, but it can also be envisaged for reasons of simplicity of embodiment to form the stampings and then bring them back to the cap by welding, gluing, stapling, etc.
  • the alveolate cap can be made of several elements then assembled.
  • the small thickness of the cap and its flexibility allow the helmet to be adjusted to the size of the cyclist's head by simple adjustment of the chin strap by having a limited number of helmet sizes.
  • This adaptation system can be of the foam "head circumference” type, adjustable and fixed to the helmet by bonding or stapling welding, or even “floating cap", consisting of a head circumference and helmet adaptation straps on the head.
