History of ABS-avalanche airbag starts curious. Because of my experience with "snow layers" put in the 70 years  some local verderer a patent of avalanche airbag. One times in winter he transported shot animal on  back. On the steep terrain in a strained dives he wals to save power sliding on snow. Several slipped, pulled while smaller avelanche but never was completely filled. Hi faught it was because he added volume of his body in the form of an animal ... After further experiments with balloons and tied big cans the idea avalanche airbag. First I have this question in collaboration with Research Center Alliance and later moved to Franhoferovým institute a system to the patent application. I obtained a patent in 1980. After the experiments based automotive airbag and development of carrier system, I could in 1985, together with Bavarian mountain service, to introduce the first fully functional ABS avalanche airbag. It happened at the winter ISPO in Munich.

ABS airbag is a system that prevents the complete burialing of the avalanche. One pulling the handle on the starters pack in a few seconds, two airbags inflate the volume of 170 liters and the actual volume of the body increasing approximately 1.5 times. The rest is done by a simple physical law - if more particles moving at the same time, the largest float on the surface. The same happens in the fall of avalanches. Added volume of 170 liters of ABS backpack provides the necessary lift for a person to remain in a surface. Backpack must of course be firmly connected with the body skiers, which provide, inter alia, buckles and metal instead of plastic on the straps.
