The six-point racing harness is more commonly used in racing cars, which is similar to that of jet fighters. Includes: 2 upper body harnesses at the shoulders, 2 lower body harnesses at the thighs and 2 at the hips. The 6 racing harness converge at the buckle, and 6 crisp "da da" sounds can be clearly heard when the racing harness is fastened.
Although the appearance of the 6-point racing harness is simple, it is the result of years of continuous research, testing and development by relevant personnel following the principle of safety. Before it can be approved as a special safety device for racing cars, it must also pass a series of tests. These tests include the strength of the device, the performance test of the buckle that can be opened quickly (in an emergency, the racing harness driver can open the buckle with one hand), the test of the racing harness and fixing parts, the dynamic test of the first-level crash dummy, etc. Only when all the tests are passed can the racing harness device be officially put into use.
When the racing car collides and decelerates, this kind of racing harness can effectively prevent the human body from being thrown out of the car due to its speed being higher than the speed of the car. At the same time, this kind of racing harness has sufficient pretension. At the moment of a car collision, ensure that the driver still has enough room to move, otherwise the huge pressure on the chest will be fatal.
According to the FIA standard 8853/98, each fixing point of the racing harness must be able to withstand a load of 14.7kN, which is equivalent to a mass of 1470kg. The width of the racing harness must be between 44mm and 76mm (shoulder and leg), and between 50mm and 76mm (waist). The specific width is determined according to the most comfortable position for the driver. Unlike the adjustable roll-type automatic racing harness used in civilian cars, the Racing harness used in racing competitions is tailor-made for each driver. For the driver, the only thing that can be adjusted is the shoulder belt. Pulling the racing harness up is extremely difficult due to the tightness of the racing harness, so the drivers have to use mechanical skills to buckle the racing harness and hold it as firmly as possible.
