Half body type
According to different types of operation and wear, it can be divided into full and half seat belts:
1, Full Body fast Harness, that is, the Harness wrap the whole Body, equipped with the waist, chest, back of a number of suspension points. It can be disassembled into a bust safety belt and a bust safety belt. One of the biggest applications of full seatbelts is the ability for rescuers to operate in a "head down" manner without having to consider the seatbelt slipping off. For example, in deep well rescues, rescuers need to go "head down" to get close to the trapped person.
2, Half Body fast Harness, that is, the Harness only covers the Body (generally the lower Body, but like the chest Harness, used for the upper Body protection). The range of use is narrower than that of full seatbelts and is commonly used for "seat suspension".
The safety belt parameters are working tension (WS) and blasting tension (BS). The above parameters are also different according to different standards and manufacturers.
