Introduction To Three-point Seat Belts

With the birth of automobiles, car seat belts have also appeared,- - three-point seat belts have been the most widely used and far-reaching safety innovation technology for more than a hundred years. A three-point harness has three attachment points that can be fastened to both the shoulders and the waist. This seat belt is characterized by the moment of a collision in the car, when the occupant has not yet moved forward
The webbing will first be tightened, and the occupant will be immediately tied tightly to the seat, and then the webbing will be locked to prevent the occupant from leaning forward, effectively protecting the safety of the occupant. The invention is said to save a life every six minutes worldwide. It is considered one of the most important security innovations of all time.
1. Brief introduction to the content
Despite the challenges in meeting comfort requirements, seat belts have come a long way in many other areas. In the 60s, we ushered in the inertial reel type automatic seat belt system. As long as your body pushes forward, this system locks the seat belt. In the 70s, a system reminding people to wear seat belts surfaced. If you don't accept the reminder, the system will beep annoyingly. Today, cars equipped with seatbelt warning devices are nothing new. Cars with this device can anticipate an impending accident and tighten their seat belts before crashing. In 1981, Mercedes-Benz S series limousines were the first to be equipped with seat belt pretensioners, and today, this device has been popularized in many ordinary cars.
2. Development
Today, we may see four-and-a-five or even six-point seat belts, which are often used in special occasions such as racing cars and child seats. Seat belts are moving towards smarter initiatives such as more electronically controlled and even inflatable seat belts. That said, seat belts still play an important role in the automotive industry. As a Volvo executive said a few years ago, every car bears the Nilsboling imprint.
