FR2717990A1 - Safety helmet adaptable to use for different sports - Google Patents

Abstract

The helmet has a cap (10) and a shell is fixed to its upper part. Tongues on the base of the shell engage in notches (9) in the cap and the base of the shell rests on a projection (7) round the cap. The shell covers holes (6) in the shell and their covers (5) and it has a vent at the back. The shell is fixed to the cap by strips of hooked pile fasteners (3) bonded to them. A screen is held in the opening (8) above the chin strap (11) by an elastic strap which passes round the cap.

Description

-I-

  The present invention relates to a device allowing

  so much to adapt the same cascue to different sports. This adaptation is traditionally obtained by replacing or removing an element fixed on the cap to

  using screws; this requires the use of a screwdriver.

  Only two types of helmet allow these trans-

  training; they are limited to two adaptations.

  - The first is a road helmet, which can be adapted to an all terrain helmet, by replacing the screen with

a visor.

  - The second is a trail helmet, consisting of a screen and a visor: It can be adapted for everything

  ground by removing the screen, while keeping the visor.

  I5 It cannot be adapted in road configuration, the visor

  part of the screen fixing system.

  This type of modular helmet is interesting for the user practicing two disciplines; even if its cost is higher than a traditional helmet, it remains much lower than the purchase of two corresponding helmets

each to a discipline.

  It would be much more interesting for the manufacturer and

  for the user, if it was not limited to two adaptations

  tions. The ventilation of a helmet improves the

  comfort, which reduces fatigue and therefore reduces the risk

  than accident. It also makes it possible to best adapt the helmet to atmospheric conditions, by regulating

the air intake.

  This breakdown is traditionally obtained by

  two holes drilled in the front part of the cap.

  These are generally equipped with a flap coming

  obstruct the air inlet, allowing the ventilation to be regulated

  tion. This flap system does not allow the helmet to be ventilated: open, it ventilates it, closed, it does not allow the air to

  escape and thereby ventilate it.

  Some cascue have a third port

  positioned at the top of the cap.

  -2- The problem with this is that it is horizontal, parallel to the movement of air on the cap. What imposes the use of a scoop forcing

  the air to enter the opening, which must be able to detach

  expensive of the cap, under the effect of a tangential shock. These drawbacks limit the installation of orifices, outside the frontal zone, which does not allow sufficient ventilation, when used in large

  heat; whereas the French standard authorizes the place-

  IO ment of 20 orifices of 20 mm2, for a total of 400 mm2.

  The device according to the invention makes it possible to remedy these drawbacks, or to reduce them. It indeed has according to a characteristic first, a cap

  provided with a projection, the design of which forms notches.

  I5 This projection allows the support of an element which I call a cuckold. It partially covers the cap in its upper part, this yes authorizes the installation of ventilation holes, over the entire covered area. These orifices

  are fitted with a bailer, which can rotate to I80, which

  according to its positioning, ventilate or ventilate the

  helmet; by directing the air intake of the scoop towards the

  Before you ventilate the helmet, directing it towards the rear

we air it.

  The base of the shell is provided with tabs, it takes the exact shape of the projection and its notches, in order to fit perfectly on the cap, so

  that these two parts become one. The lan-

  spouts allow the guidance of the hull during its positioning, but also prevent any rotation,

once it is in place.

  T hull is fi: -: e on the cap by bands "VEL-

  CtiR ", this cooker and remove and reposition it

  fsci ement. This fastening t is made possible by the im-

  bearing contact surface, between 1, shell and cap, this implies the use of "VELCL0 Dû", when one wishes to obtain a strong fixation; but apart from the fixing points, the shell and the cap are not in contact, their design is such that it allows the passage of air between them. A vent is positioned at the rear of the hull, allowing air to flow and form a

  air flow feeding the ventilation holes.

  The use of the shell improves the safety of the user, by the fact that the helmet has in its

  most stressed part, double thickness of protection

  tion, shell plus shell, the space given between these

  two parts reduce the impact of a shock, by offering-

shock absorber.

  It also allows by its replacement by different

  shell annuities, to modify the aesthetics of the helmet and its characteristics, to best adapt it to different

  sports disciplines. The base and the fixing points of all the hulls remain identical.

  A second element, a screen, completes and widens the possibilities of adaptation of the helmet. This screen

  looks like a pair of sports glasses, unlike

  rence close, that it does not rest on the face of the user

  IO0 sator, but on the cap and its chin rest.

  It is positioned on the rod which covers the opening

  eg cap and chin rest. It is provided in its inner part with projections, serving as a guide during

  of its positioning and preventing it from sliding.

  I5 It is held in position by pulling, performed

  by an elastic band, the ends of which are attached to it

  linked on each side. So it's easy to remove and replace it, either with a pair of sports glasses,

  or by one of the different elements constituting the range

me of screens.

  The cuckold and the screen each form a range of different elements; they differ either by

  used materials. their realization, either by trans-

  training modifying their characteristics or their

275 aesthetic.

  According to alternative embodiments illustrated or not, the front part of the shell (I) is extended to form a visor, while that of the shell (I ') is

  convex in shape, like the cap of a road helmet.

  The screen (I2) is translucent, it can be smoked, ventilated,

  or anti-fog. The projections (I3) of the screen (I2) which re-

  take the internal shape of the rod (8), can limit it

  der in part or in whole, depending on whether or not it is desired to obtain a seal, between the rod (8) and the screen

(I2).

  The fact of using elements such as the shell or the screen, would allow the manufacturer to have a full range of helmets, using the same shell mold and interior trim, hence a production cost much lower than the creation of a range, helmet by helmet. He would also have the possibility of retailing the various shells and screens, constituting his range of helmets, which would allow the user to adapt his

  helmet, to the different disciplines he practices.

   20 With reference to these drawings, the device comprises

  two types of elements: A shell (I) and a screen (I2), for-

  each mant a Woman of different elements, adapting

on the same cap (IO).

  The base and the tabs (4) of the shell (I) repo-

  feels on the projection (7) and its notches (9) located on the cap (IO). The shell (I) covers the upper part of the cap (IO) and conceals the orifices (6) and their scoops (5); it is fixed on the cap (IO), using "fLO-0 X" strips (3), so the two narties are glued in screws on each of them. A vent (2) is positioned at the back of the cuckold (i) to allow the air in = offered between it and the cap (10) to evacuate and form ui

  air flow supplying the orifices (6).

  The screen (I2) is positioned on the rod (8) which

  covers the cut of the cap (IO) and its chin-

nier (II).

  -5-- It is provided in its inner part with projections (I3) serving as a guide during its positioning and preventing it from sliding. It is pressed against the rod (8), by traction carried out by an elastic band (I4), the ends of which are connected to it on each side.

  The projection (7) and its notches (9) are positioned

  born on the cap (IO) in the extension of the plane of vision, so that they are hidden by the elastic band (I4) of the screen (I2) or of any pair IO0 of sports glasses, so to make invisible the junction of the shell (I) and the cap (IO), when the

  elastic band (I4) is in place on the helmet.

  The scoops (5) are made of rubber, the

  pless of this material makes it possible to introduce the cylinder of I5 the scoop (5) slightly in force in the orifices (6), this

  which gives it good support in any position

  tion and authorize to rotate it on itself, without having to

remove it from the hole (6).

  The device according to the invention is particularly intended to adapt the same helmet, to different sporting disciplines. -6-
