Definitions

  • the invention relates to a two-part crash helmet and protective helmet, optionally provided with a window that can be closed by a window, which is particularly intended for motorcyclists and completely encloses the head to be protected.
  • the two parts of the helmet are connected to one another in an articulated manner by means of a hinge and can be firmly connected to one another by means of closure elements.
  • a crash and protective helmet that completely encloses the head of the helmet wearer - a so-called full-face helmet - ensures relatively good protection against injuries in the event of a fall or accident of the helmet wearer. It has turned out to be disadvantageous, however, that such helmets can delay first aid measures or first aid after accidents or first aid, such as clearing the airways or artificial respiration, since removing the helmet from the head of the injured person is very careful and with a great deal of effort Care must be taken, otherwise there is a particular risk that cervical spine injuries can be aggravated and paraplegia may also occur. For this reason, lay helpers are advised not to free a motorcyclist who has had an accident from his helmet.
  • Glasses wearers find it disadvantageous that the glasses must be removed before putting on a conventional full-face helmet and only after the helmet has been put on with the visor lens open through the helmet window must be put back on relatively cumbersome. The same applies to removing the helmet.
  • Protective glasses with an elastic strap can only be worn by users of conventional full-face helmets if the visor of the helmet is completely removed and the elastic strap is placed around the outside of the helmet.
  • a helmet is known, the lower helmet opening of which is designed to have a relatively small area and fits snugly against the neck area of the helmet wearer with a cuff made of flexible material.
  • This cuff consists of two parts that can be opened to put on or take off the helmet after unlocking two locking mechanisms on the side.
  • the lower helmet opening is relatively small, which gives the helmet an approximately spherical configuration. As a result, the draft inside the helmet remains low at higher speeds and the head can still be turned even at relatively high speeds.
  • the low air throughput has a disadvantageous effect at a slow driving speed, especially at summer temperatures, since a higher air throughput is desirable under such conditions.
  • Putting on and taking off the helmet is no less complex than with conventional full-face helmets; although it is not necessary to operate a chin strap fastener, since the helmet is not secured by a chin strap, but by connecting the neck parts together.
  • the removal of such a helmet from the head of an accidentally unconscious helmet wearer is more complicated and time-consuming than with conventional helmets (cf. "Motorcycle", issue 8, p. 145, 1982). After all, when you put on and take off this helmet, glasses wearers also have to remove their glasses.
  • a divisible helmet is known, the chin strap can be opened up together with the folding visor after unlocking two closure elements.
  • the face of the wearer to be quickly exposed for first aid measures or first aid, it is considered disadvantageous for the everyday use of such a helmet that it takes a relatively large amount of time to put on or take off, and that it is essential to properly put on the chin strap.
  • the lower helmet opening is just as extensive as with conventional full-face helmets.
  • the invention has for its object to provide an integral helmet that can be put on and taken off by its user, whether wearing glasses or not, quickly and easily with the least possible effort, but above all an accident victim in a simple manner even by inexperienced persons without risk for the cervical spine of the injured person can be removed from his head in order to be able to provide first aid or medical first aid without hindrance and immediately.
  • the invention has for its object to provide an integral helmet that enables its user to provide effective protection against cold and drafts inside the helmet.
  • the dividing line between the two helmet parts in the rear region of the helmet is in a preferably curved plane, which is behind the lower edge of the helmet vertical main plane going through a point between the rear helmet apex and the upper helmet apex.
  • intersection of the curved plane containing the dividing line with the vertical main plane in the longitudinal direction is preferably in the vicinity of the rear helmet apex, but not further away from this than about 1/3 of the distance between the rear helmet apex and the upper helmet apex.
  • the helmet 11 consists of the two helmet parts 12 and 13.
  • the dividing line 14 between these two parts is located in the rear area 15 of the helmet 11 and is preferably in a curved plane XX. It goes from the lower helmet edge 16 on both sides of the helmet 11 in each case behind the vertical main plane in the transverse direction 17 and extends to a point 18 which is located between the region of the rear helmet apex 19 and the upper helmet apex 20.
  • the intersection 18 of the plane X-X, which contains the dividing line 14, with the vertical main plane in the longitudinal direction 21 is in the vicinity of the rear helmet apex 19, but not further away from it than about a third of the distance between the two helmet apices 19 and 20.
  • the two helmet parts 12 and 13 are articulated to one another in the region of the vertical main plane 21 by means of a stable hinge 22.
  • a stable hinge 22 In the area of the lower helmet rim 16 there are quick-release elements arranged on the inside on both sides of the helmet, which snap into themselves when the two helmet parts 12 and 13 are folded together and lock them and which can be unlocked again by means of the push buttons 23.
  • the user grips the front helmet part 12 on the chin guard 24 with his one hand and places it inclined forward and in front of and on his face so that the chin guard 24 rests with his chin pad against the chin.
  • the rear helmet part 13 is held in the folded-down position and then the helmet 11 is tilted backwards and placed on and around the head of the helmet wearer. Finally, the rear and front helmet parts are firmly joined by light pressure on the rear helmet part 13. The helmet is removed in reverse order after unlocking the quick-release elements by pressing the buttons 23.
  • a separate chin strap is not necessary with this helmet; the chin strap only needs to be adjusted once to its appropriate width and remains in a hooked position for normal use.
  • the helmet can easily be removed from the head of an injured or unconscious helmet wearer lying on the floor. After unlocking the quick-release fasteners by depressing the push buttons, the front helmet part 12 can be tilted forward and upward, if necessary after loosening the chin strap, in order to be able to pull the rear helmet part 13 under the head of the helmet wearer effortlessly and safely. An essential movement that can be life-threatening and / or displacement of the head or cervical vertebrae if cervical spine injuries are present The injured person's pillar is not required.
  • a helmet designed according to the invention is not put over the head from above as in conventional helmets, but rather, as described above, is put on or put on from the front, so that there is the option of using a snap fastener or Velcro elements on the lower edge of the chin guard attachable elastic cover to protect the lower chin and neck area of the helmet wearer from drafts and cold. This does not hinder the putting on or taking off of the helmet and can remain attached to the helmet during the entire cold season.
  • the risk of rebreathing of breathing air that has already been used can be avoided, if necessary, by appropriately sized ventilation slots, expediently by those that are open at low speed, but are closed by themselves at high speed by air pressure or the air flow.
  • the edge 25 of the front helmet part 12 can protrude somewhat from the edge 26 of the rear helmet part 13 along the dividing line 14, so as to form a tear-off edge for the air flowing past, which has an advantageous effect on the forces acting on the helmet 11 at high speeds .
