In the early stages of mountaineering, there was no seat belt. The climber tied the rope around his waist and the protector also protected it by increasing friction at the waist. But the flaws of this method are obvious, and the ribs will produce intense pain because of the increased force, and this pain will not end because of the end of the climb, but will continue for some time after the end of the climb. But what's worse is that if you fall during a climb, the consequences are fatal. The impact force reaches 3.7KN. This is only a medium-strength fall, but as long as this kind of crash occurs, the climber will lose consciousness and even die after a few minutes because of the huge pulling force on the waist. So design safety comes with two ultimate goals: to withstand the impact and distraction forces.
Nowadays, climbers will use seat belts to climb. Seat belts have become indispensable for climbing. General safety belts include the following designs: Thickened widening lumbar cushions, leg loops, protective rings, and equipment rings. With these designs, it will be more comfortable and safe whether it is falling, falling, or hanging on the rock wall. Seat belts have also been refined: specifically designed for athletic climbing, big rock climbing, or specialized mountain climbing, but a genuine premium seat belt will cover these needs.
