Definitions

  • the invention relates to a helmet.
  • Helmets are known to protect the human head and are therefore tied to the ergonomic dimensions of the same.
  • the outer shape of the helmet is an aesthetically pleasing configuration which meets functional requirements.
  • a helmet primarily protects those zones of the head which are in need of protection.
  • the dimensions of the helmet define how it fits on the human head.
  • a lockable neck strap defines the protective position of the helmet on the head.
  • the object of the present invention is to provide a ski and/or snowboard helmet which is intended for use in alpine locations and at which the application area has been extended.
  • helmets may differ in respect of dimensions and aesthetic designs, the respectively current, valid DIN standard defining the dimension-specific limits for safeguarding the anatomically defined protection zones. There are therefore a number of different models rather than just one archetype.
  • a helmet with additional functions.
  • One such additional function is the separation of the locations where the user inhales oxygen (O 2 ) and exhales carbon dioxide (CO 2 ) while wearing the helmet.
  • This additional function makes it possible for the respective user, in this case an avalanche victim to survive longer under an avalanche of snow.
  • any density of snow is permeable enough to allow an avalanche victim to be supplied with sufficient O 2 , the most frequent cause of death for avalanche victims up until now has been suffocation. This is due to the fact that the victim, rather than dying from a lack of O 2 , repeatedly inhales the CO 2 -containing air which he has exhaled.
  • the invention is distinguished in that it is possible according to the invention, via a mouthpiece which is connected to the helmet and, in the event of an avalanche, is located in the victim's mouth, to inhale the O 2 -containing air from the snow and, in addition, to expel the CO 2 -containing exhaled air such that it is not inhaled again and, as a result, represents a potential cause of death.
  • FIGS. 1 and 2 show a helmet according to the invention, although the user is not included in the illustration of the FIGS. 1 and 2 .
  • the helmet wearer can if required, that is to say if he is endangered by an avalanche, actuate a triggering button 8 using pressure.
  • This unfolds a folded-up, rubbery hose 6 which is located directly in front of the user's mouth, such that the respective user can reach this hose, in its unfolded state, simply by opening his mouth. If the individual is completely buried by the avalanche, that is to say if even his head is buried, he then keeps the hose-like part 6 in his mouth, additionally held by the jaw muscle (mouthpiece similar to a snorkel).
  • the helmet has, as oxygen-intake region, openings 1 which are distributed over the entire helmet and, in order to prevent blockage by snow, are provided with a kind of permeable lattice structure.
  • the cavity 2 which forms between the outer shell 4 and inner shell 3 a serves here as a kind of artificial air space.
  • This air space is very advantageous as an intermediate zone in order to reduce the mechanical resistance during the intake of O 2 -containing air to the extent where the victim does not become exhausted within minutes as a result of trying to overcome excessive resistance caused by snow clogging up his airways, and consequently physically no longer capable of taking in the oxygen available.
  • a frequent cause of death for avalanche victims is therefore suffocation, brought about by a lack of oxygen and repeated inhalation of their own CO 2 -containing exhaled air. If the victim, then, sucks on the hose 6 , the cavity 2 means that he filters, for the most part in a resistance-free manner, the O 2 -containing air from the avalanche snow in his immediate surroundings. If the victim then breaths from beneath the avalanche, the channels of air are directed via two control valves 5 a and 5 b.
  • the control valve 5 a which is air-permeable on one side, ensures inhalation of the O 2 -containing air via the mouth hose 6 and, at the same time, prevents the CO 2 -containing exhaled air from flowing back in this direction.
  • the control valve 5 b which is likewise directed to one side, ensures that the CO 2 -containing exhaled air passes through only the valve 5 b, and likewise cannot flow back, and therefore leaves the helmet in the desired direction through the cavity 7 . In the central neck region, the CO 2 -containing exhaled air is expelled to the surrounding snow via the outlet opening 9 .
  • a hose-like extension which increases the distance between the respiratory-air intake region and the respiratory-gas outlet region, in order to minimize the probability of the CO 2 -containing exhaled air being inhaled again.
  • This extension may be located above and beneath the ski clothing and likewise has, at its end, an opening from which the CO 2 -containing exhaled air passes out.
  • FIG. 1 shows the perspective view of a helmet according to the invention which has its shell structure partially opened up to reveal the functioning of the helmet via the layered construction and all the other elements.
  • FIG. 2 shows the rear view of a helmet according to the invention to which the hose-like extension 9 has been connected.
