Definitions

  • This invention relates to a protective recreational helmets according to the prior art portion of Claim 1, e.g. devices used to diminish the acceleration caused by recreational accidents that otherwise would lead to head injuries, and include a hard outer shell, an impact-absorbing liner and a retention system.
  • Protective recreational helmets used today are formed to be used in a special type of recreational activity. In some extent helmets formed for one special recreational activity can also be used in other activities and give some protection. The best protection, however, is given by a helmet formed just for the special activity. Children who often take part in a great number of different activities would thus, for the best protection, need varied types of helmets for the various recreational activities. As children also grow they will need new sizes regularly. This leads to that parents often would have to buy several helmets each year.
  • US-A 3 568 210 discloses protective headgear helmet according to the prior art portion of Claim 1, wherein a single standardized shell is provided and wherein several liners are available which liners have different thicknesses and thus different inner sizes to fit different wearers. After selecting a liner of correct size, the liner is attached to the shell, eventually by means of a layer of adhesive. By this protective headgear a dealer, or similar, might reduce the number of helmet shells in stock.
  • the major object of the present invention is to create a helmet system that can be used for several different recreational activities. Another object is to extend the life of the helmet, or at least of some parts of the helmet.
  • This invention stands in the same relationship to conventional helmets as an adjustable wrench to a fixed wrench.
  • the fixed wrench is a superior tool in the correct context, but in a differing context it cannot be used at all.
  • the helmet system according to the invention is thus a flexible helmet which can be user adapted to any number of applications by means of user selected variation of the helmet subsystems.
  • the helmet subsystems which together provide a finished application are the following:
  • fig. 1 a-1 show side elevations of helmets according to the invention intended for different recreational activities
  • fig. 2a-2b show side elevations of two different liners for use in the helmet according to the invention
  • fig. 3a-3c show schematical side elevations of a helmet according to the invention provided with different retention webbings
  • fig. 4a-4b show a retention webbing for use as a chin-strap and how this chin-strap is mounted in the helmet
  • fig. 5a-5b show a retention webbing for use in a three-point retention system and how this is mounted at the rear of the helmet
  • fig. 6 show for two different helmet shells how the different shells include identically formed parts
  • fig. 7 show in a perspective view how the shell and the liner are joined by means of the retention webbing.
  • the shell 1 is the historically recognized antecedent to modern helmets.
  • the ancient helmet was merely a hard casque of leather, which would protect the bearer from blows.
  • the shell 1, seen in fig. 1a-1f is defined as a hard outer covering, preferably of a plastic material, the purpose of which and therefore the form of which can vary from application to application.
  • the shell shown in fig. 1a
  • the shell In ice-hockey the shell (shown in fig. 1a) must be stiff, to resist the point loading from an impacting puck, and relatively closed, because of that the recreational environment is cold and chilly.
  • the shell shown in fig. 1b
  • the shell is similar to the ice-hockey shell, with the added need to provide additional thermal protection.
  • This skiing shell (1b) is fully closed, but can be thin, as stiffness is not a central demand.
  • bicycle touring shown in fig. 1c
  • the stress is on ventilation, but also on avoiding penetration by blunt objects, such as curbs and automobile door handles.
  • a specially formed shell for baseball players is shown in fig. 1 d.
  • An almost fully closed shell for moped drivers is shown in fig. 1e.
  • a similar shell can be used for hang gliding (shown in fig. 1f), but this shell is provided with through-cuts at the location of the users ears, as the user must have unimpaired hearing.
  • the liner 2 is, according to this invention, a component which can be varied according to the needs of the user.
  • the liner shown in fig. 2a can for example be used for bike riders together with the shell shown in fig. 1 c, but this liner can also be used for baseball players together with the shell shown in fig. 1d.
  • a different liner, which also provides ear protection, is shown in fig. 2b. This liner can be used by moped drivers in the shell shown in fig. 1e, and for hang gliding together with the shell shown in fig. 1f.
  • the liners 2 would, in most cases, be fabricated from impact-absorbing, expanded cellular materials, such as expanded polystyrene. However, the design of each liner 2 requires that it fit the several outer shells 1 to which it is intended to be paired. Thus all liners 2 have essentially the same top outside shape, as can be seen from the top shape of the two liners shown in figs. 2a and 2b.
  • the retention system 3 is a component which can be varied in accordance with the different needs in different applications.
  • a two-point system is shown in fig. 3a and can be used in those recreational contexts where helmets traditionally feature such retention systems, e.g. in ice-hockey.
  • an elastic no-buckle retention system as shown in fig. 3b, an be substituted.
  • a three-point retention system as shown in fig. 3c, can be used.
  • the shell 1 in contrast to conventional helmets, the shell 1 is not permanently affixed to the liner 2 or to the retention system 3. Instead the shell 1 is affixed to the liner 2 and/or the retention system 3, for example by use of Velcro® type fasteners or by the loop-through principle for the retention webbings as described below.
  • the inner shape of all the shells and the outer shape of all the liners have to be essentially the same.
  • a number of fixed parts 6, 7 of the shells 1 and of the liners 2 have been given almost identical form (cf. fig. 6) to make it possible to combine them in the various fashions and to affix them to each other by means of the retention webbings 3.
  • the shells 1 and the liners 2 have also at the same locations been provided with slots 8 through which the retention webbings 3 can be pulled through.
  • conventional helmets have rivets of steel or plastic which hold the webbing in place during use, the webbings according to this invention are held in place with a snare loop as shown in figs. 4b and 5b, which allows the webbing loading to be dispersed into the liner material, which is typically non-ductile and therefore brittle.
  • the retention system according to the invention will typically use a woven webbing.
  • the webbing shown in fig. 4a is intended to be used as a chin-strap 4, and can be looped through the shell 1 and liner 2 as is shown in fig. 4b.
  • the webbing shown in fig. 5a intended for the rear position of of a three-point system, and includes a branched snare loop 5, which allows the left and right rear webbing to be jointly fastened to the liner and the shell as shown in fig. 5b.
  • the ends of the left and right rear webbings can by means of a buckle 9 be attached to the chin- straps 4 as indicated in fig. 1c.
  • the shell, the liner and the retention system can be given other shapes than those shown in the drawings and described above for use in other activities.
