Definitions

  • the present invention relates to helmets for protecting the head of a user for sports practices.
  • the invention relates to helmets for skiing, snowboarding, cycling, skateboarding, rollerblading, kayaking.
  • Such helmets are mandatory in sports practices such as mountain bike, ski racing, speed skating or roller skating called “aggressive”.
  • sports practices such as mountain bike, ski racing, speed skating or roller skating called “aggressive”.
  • the use of such headphones is also highly recommended for recreational cycling and skiing.
  • a first of these techniques is that widely used for the manufacture of moped helmets and motorcycles and for some ski helmets.
  • a rigid shell or cap and relatively thin, is produced by injection (PC, ABS) or by any other suitable means (for example by stratifying different layers of fabric impregnated with resin).
  • This hull is then filled with elements of comfort and / or damping comprising a sub-cap of expanded polystyrene (EPS), foams, fabrics.
  • EPS expanded polystyrene
  • such a helmet can cover the entire skull of the user, but also the ears, or even the jaw of the user.
  • this technique it is easy to achieve mass production and costs reasonable one-piece hulls that have a wrap maximum of the head. Indeed after injection of the hull, even when this one is very enveloping, it keeps a certain deformability allowing the release.
  • the disadvantage of this technique is that the helmets as well realized are rather heavy. But the weight of a helmet is a criterion determining not only for the competition but also for leisure practices where the user will have the impression that his or her helmet is heavy, the less he will want to wear it.
  • in-mold that is to say, "in the mold”.
  • the helmet is made in the same mold.
  • the helmet is equipped a chinstrap, possibly a comfort lining and others accessories.
  • the outer skin of the helmet called “microshell”.
  • This skin may for example be a leaf of polycarbonate.
  • This sheet is thermoformed to take the final form of the outer surface of the helmet.
  • This sheet is thin ( ⁇ 1 mm in general). After deburring and cutting, it is placed in the mold with a material of polystyrene type. The heat and the steam introduced into the mold trigger the expansion of polystyrene until it occupies all the mold volume, and binds to the polycarbonate sheet.
  • helmet At demolding, helmet consists of a thick overmolded expanded polystyrene shell on an outer skin. Such a helmet has no flexibility and it is why, unless you use expensive molds, you do not make that technical than light helmets whose enveloping surface does not does not include the ear coverage area. For example, if we approximates the enveloping surface of a helmet to a sphere, it is said that this technique avoids having an enveloping surface that does not can be contained in a half-sphere. In practice, we use rather this technique for summer helmets whose hull does not include parts protecting the ears.
  • a means used for the decoration of a helmet is to place in the mold several leaves, each of different color. After the passage in the mold and the expansion of the polystyrene, the helmet will present portions of its outer surface of different colors.
  • This technique of decoration also has its limits in terms of the quality of the finish because, given the imprecision of the positioning of the leaves in the mold, it is necessary to provide a large clearance (several millimeters) between the two leaves. On the finished product, expanded polystyrene will remain visible between the two colored leaves and the border between the two leaves will be irregular.
  • the objective of the present invention is to provide a helmet whose manufacturing is devoid of the aforementioned drawbacks.
  • the objective of the invention is also to provide a range of helmets intended for different uses but whose manufacture and development is less expensive.
  • the objective of the invention is also to provide a helmet that can to be used in different sports practices.
  • a helmet that has a rigid shell made of an expanded polystyrene material molded onto a skin outside and comprising a rigid arch which has an arch headband applied to said shell and both ends of which are equipped of ear covering devices.
  • a helmet that comprises a shell and a plurality of additional elements, each provided for the use of the helmet during a sporting practice particular or special atmospheric conditions.
  • the rigid shell is obtained according to the so-called technology "in-mold", which allows the realization of a relatively lighter hull than in the case of a traditional construction of a rigid injected shell.
  • FIG 1 depicts a helmet that includes a shell 2 obtained by the in-mold technology. This one is made of an expanded polystyrene cap overmolded on an outer skin 3.
  • the outer skin 3 also called “microshell”, is pierced with ears 6 placed in correspondence with openings in the polystyrene cap. These ears 6 allow fresh air intake inside the helmet.
  • the hull has a throat 4 which crosses its outer surface from side to side from the temporal area left to the right temporal zone (visible in Figure 1). This throat 4 which constitutes a slight recess of the outer surface of the helmet is provided to receive the bow 7.
  • the helmet is retained on the head of the user, thanks to a chinstrap 5 consisting of a set of straps flexible comprising on each of the sides of the helmet a jugular strap before 8, a rear chinstrap 9 that join together to form the jugular proper.
  • a chinstrap 5 consisting of a set of straps flexible comprising on each of the sides of the helmet a jugular strap before 8, a rear chinstrap 9 that join together to form the jugular proper.
  • the internal cladding of the helmet is not visible in this figure and will be described later.
  • Figure 2 depicts the same helmet as Figure 1, which has been arch 7.
  • the arch 7 is embedded in the groove 4 and is fixed on the shell.
  • At both ends of the arch are fixed two cover devices 10. Only the one on the right is visible in figure 2. They are consisting of foam cushions covered with a fabric.
  • Fixing the hoop to the hull can of course be done by any appropriate means permanent or not.
  • a fastener that can be detached and replaced by the user himself, for example by using screws associated with inserts or snaps to allow the user to wear his headphones with or without ear covering devices.
  • FIG. 3 describes a helmet whose hull is identical to that of the Figure 1.
  • a headband 11 is embedded in the groove 4. This arch is described independently and in perspective in Figure 4. It is consisting of a band 12 which extends at its ends by wings 13.
  • the strip 12 and the wings 13 constitute a single piece made by injection of a plastic material.
  • FIG. 5 shows a sectional view of the helmet shown in Figure 3.
  • the shell 2 consists of a polystyrene cap 15 covered with the 3. It should be noted that for the sake of clarity of the drawing, the thicknesses of the different pieces are not to scale. So the skin outer 3 actually has a thickness generally less than 1 millimeter.
  • the bow-ear 11 belt the hull. His headband 12 is applied against the outer skin 3 and is attached to it by any means appropriate, permanent or not. Beyond the band 12, the arch extends in two wings 13 which are substantially oriented towards the inside of the volume helmet to ensure a more snug wrapping of the head and particular of the region of the ears.
  • the band 12 and the wings 13 are part in one and the same room. On these wings 13 are fixed the devices of ear covering 10. When assembling the hoop 11 on the hull 2, the bow is deformed elastically so as to move the wings 13 towards outside.
  • the helmet is on the other hand provided with an inner lining 14 which is disposed inside the shell 2 so as to be in contact with the head of the carrier.
  • the dressing provides a comfort function and a function of keep the helmet on the head. It is formed of foam elements fabric-wrapped and is disposed fixedly or removably within the shell for example by means of Velcro strips.
  • FIG. 6 describes another helmet whose shell 2 is identical to that helmets previously described so far.
  • This shell 2 is associated with a chinstrap 16 whose band is embedded in the throat 4 arranged on the outer skin 3 of the shell.
  • the chinstring 16 is stuck on the outer skin 3.
  • the chinstrap 16 is described independently and in perspective at Figure 7. It comprises a band 12, two wings 13 and a chin strap 17.
  • the chin guard 17 protects the jaw and face in the practices most risky sports such as mountain biking downhill.
  • wing level 13 are fixed ear covering devices consisting of a foam cushion wrapped with fabric.
  • the cushion has substantially an annular shape so that a cavity giving the ear more ease be created and also not to interfere with the hearing.
  • the wings 13 are, on the other hand on the other hand, pierced with a plurality of holes to facilitate hearing.
  • the hoop-chin guard 16 is a monoblock piece obtained by injection. To be able to be put in place it is necessary to deform it elastically by spreading the wings apart from each other. In case the material chosen to achieve the hoop-chin guard would not be sufficiently elastically deformable, one can imagine a separation in two pieces of the headband 12.
  • the hoop-mentioned 16 is equipped with means of retaining the strap of a vision mask (not shown). These means have the form a hook 22 that prevents the strap of a mask from sliding upwards on the outer surface of the helmet.
  • the purchase of a single helmet shell such as the one of FIG. 1 and a plurality of arches 7, 11, 16 will allow it to multiple uses and multiple practices, provided that the different hoops 7, 11, 16 are releasably secured to the user to exchange them. So for a little dangerous sport practiced by time hot, the helmet is used without hoop, use leisure skiing will be done with the single arch 7 which guarantees the thermal protection of the ears while that the practice of ski racing will be done with the bow-ear 11 or even with the chinstrap 16.
  • FIGs 8, 9 and 10 describe a range of three helmets according to a alternative embodiment of the invention.
  • the hull 2 includes a single block of expanded polystyrene overmolded on two sheets of polycarbonate.
  • the first sheet 18 covers the top of the skull and is C1 color.
  • the second sheet 19 covers the nape and is C2 colored.
  • the simple hoop 7, at both ends of which are fixed cover devices 10 is placed on the shell so as to cover the edge of each two sheets 18 and 19 at the separation between them. So the separation between the different colors is clear and precise in the extent where it is made by the edges of the band 12.
  • Figure 9 shows the helmet equipped with a bow-ear 11
  • This one includes a strip 12 similar to that of the single bow 7 of the helmet described in Figure 8, which extends at both ends by wings 13.
  • the hull 2 has a first color C1 above the strip 12 and a second color C2 below it.
  • Figure 10 shows an integral helmet made on the basis of a hull identical to that of the helmets of Figures 8 and 9.
  • the shell 2 also receives a visor 20.
  • FIGS 11, 12 and 13 show a range of three helmets according to another alternative embodiment of the invention.
  • the helmets include a shell 2 obtained by the "in-mold” technology and a hoop 7, 11, 16 made of a rigid material.
  • the simple hoop 7 comprises a band 12 which right through the back of the helmet, fastening means of 10 ear covering devices and frontal extensions 21 which along the front edge of the hull 2.
  • the ear bow 11 in addition to the strip 12, the front extensions 21 and the 10 ear covering devices, the ear bow 11 includes two wings 13 which are extensions of the band made of the same material as this one.
  • FIG. 13 shows a full face helmet.
  • the chinstrap 16 includes a headband 12 attached to the rear portion of the hull 2. In the extension of the strip 12 are on each side, the wings 13, then the chin rest 17. From each of the wings 13 and along the edges front of the hull 2 are placed the front extensions 21 which are join at the top of the front edges to form the visor 20. Good heard, ear covering devices 10 are placed under the 13.
  • the chinrest 17 is also equipped with a interior comfort pad in the form of foam pads wrapped in tissue. Given the complexity of the chinstrap 16, he will be able to be better to make this one into several parts, which will be assembled separately on the hull 2.
