Rock climbing harnesses provide a comfortable and safe fixed device for climbers and belayers, which can disperse the impact of falling to the waist and legs, avoiding the concentrated force on the waist and causing injuries. Safety belts usually include waist belts, leg loops and an additional connection system at the front, with the waist belt being the main force-bearing part. Safety belts can usually be divided into sitting safety belts, chest safety belts and full body safety belts.
