What are the advantages of by point seat belts?

As an important safety device in scenes such as vehicles and industrial equipment, the by point seat belt has become a standard protective component for various types of manned equipment by virtue of its scientific fixing method and flexible wearing design. It not only ensures the safety of personnel but also takes into account the convenience of use. 

Multi-dimensional fixing improves the reliability of restraint

The point-type seat belt forms a three-dimensional restraint system through multi-point fixing, which significantly improves the protective effect in the event of a collision. The common three-point seat belt is connected to the vehicle body through the shoulder and waist points and forms a triangular fixed structure with buckles. In the event of a collision, the impact force can be dispersed to the chest, abdomen and pelvis, reducing the damage caused by single-point force. Data shows that the three-point seat belt can reduce the occupant mortality rate in vehicle accidents by more than 50%, which is much higher than the protective effect of the two-point seat belt.

The five-point seat belt is widely used in scenes such as child safety seats and racing cars. Through the five-point fixing of the shoulders, waist sides and crotch, the body is firmly restrained on the seat. In severe impact or rollover accidents, it can effectively prevent body displacement and avoid secondary collisions. It is especially suitable for children, racing drivers and other groups that require high-intensity protection.

Adapt to multiple scenarios and meet diverse needs

The modular design of the by point safety belt enables it to adapt to different scenarios. In the field of passenger cars, the three-point safety belt with adjustable length can adapt to passengers of different body shapes, and users from 1.5 meters to 1.9 meters in height can find a comfortable wearing position; the two-point safety belt of commercial vehicles simplifies the installation of the middle position in the back row while ensuring basic protection, taking into account passenger capacity and safety.

In the industrial field, the by point safety belt can be used in conjunction with the safety rope and fall arrester for aerial work vehicles and engineering machinery cabs. Through the fixed points of the waist and shoulders, it prevents the operator from accidentally falling, while not affecting the flexibility of upper limb operation. The four-point safety belt in amusement facilities can restrain the body and reduce the sense of restraint in high-speed sports equipment such as roller coasters and bungee jumping machines, balancing safety and experience.

Easy to operate and improve compliance

The quick buckle design of the by point seat belts greatly reduces the difficulty of wearing. You only need to insert the plug into the buckle to fix it. When unlocking, press the release button to quickly detach it. The whole process takes no more than 3 seconds. It is easier to operate than the traditional tethered seat belt, especially suitable for children, the elderly and other groups with weak operating ability.

Some high-end by point seat belts are equipped with early warning devices. When the vehicle accelerates, brakes or tilts suddenly, the seat belt will be automatically tightened to eliminate the slack in advance and fix the occupant firmly in the seat. After the accident, it can be automatically unlocked for escape or rescue. This intelligent design not only improves the active protection but also does not increase the complexity of use.

Strong durability, adaptable to complex environments

The material and structure of the by point seat belts have excellent durability. The webbing is made of high-strength polyester fiber (breaking strength ≥ 20kN), which can still maintain stable performance after more than 5,000 tensile tests; the metal buckle is rust-proofed and has a service life of more than 5 years in a humid and dusty industrial environment.

In extreme temperature environments （-40℃ to 80℃）， the performance of the webbing and buckle of the Andian seat belt is almost unaffected, making it suitable for use in vehicles in cold regions and high-temperature workshop equipment. In addition, the surface of the webbing is mostly anti-fouling treated, and daily stains can be easily wiped off, reducing cleaning and maintenance costs.

With the upgrading of safety standards, by point seat belts are developing in the direction of intelligence and lightweight. For example, smart seat belts with integrated sensors can monitor the wearing status and remind users. The application of lightweight materials reduces weight while ensuring strength, further improving user experience and continuously consolidating its core position in the field of safety protection.
