A ski helmet has been patented for rescuing those buried in an avalanche.

It allows you to breathe and gives a signal about the location of the avalanche victim

Inventors from Kazan recently received a patent for a helmet for mountain skiing. It can not only protect a skier’s head in case of a fall, but also help him escape after an avalanche.

Externally, the helmet body looks quite ordinary; what distinguishes it from ordinary helmets is the filling. This is a control unit built into its body, a means of determining where the person buried under the snow is, as well as an air duct that supplies gas to the face area. Included with the helmet is an external air source in the form of a compressor; it is placed in the extreme skier’s backpack. It is connected to the helmet by an air duct adjacent to the back of the device. This placement reduces the risk of the air duct becoming damaged or popping out of the helmet or air delivery device when turning the head.

Through the helmet control unit, someone buried under snow can receive a signal from a means of determining his location and send a signal to an external compressor to supply air. Another important element of the helmet is the power supply. The authors of the invention propose placing it in the upper part of the helmet: the human brain has maximum heat transfer, so the power supply in this area will work longer and more stably.

The principle of operation of the device is quite simple: once under an avalanche, the skier starts the air supply mechanism and a device that signals his location. However, the helmet can do this itself: it is equipped with oxygen and carbon dioxide content sensors in the space under the helmet, and if the gas ratio is unacceptable for breathing, it will start the system without the participation of the skier, who, for example, may lose consciousness.
