“It is important to choose a car. The first start of the car is the beginning of the companion.”
There are more and more private cars, but more than 80%of the owners who go to maintenance, beauty, maintenance, and accessories are novice drivers who do not understand the market.
Until the three -point horizontal V -type seat belt invented by Nils Bohlin (1920-2002) appeared, the seat belt was not valued. At first, Polin was an engineer in the Swedish aviation industry. He was responsible for designing the pilot’s seats, which enabled the pilot to escape the cockpit as much as possible under the emergency. Later, Polin turned to study how to fix the body safely in the same place under extreme dangerous conditions. In 1958, Polin applied to Volvo Motor Corporation, and soon invented a three -point seat belt.
Polin’s three -point seat belt can across the abdomen at the same time and spans the shoulders, and coordinate the coordination through the low -level fixed point on the side of the seat. Keep its position unchanged under the effect. Using a three -point seat belt, when the vehicle occurs, it can not only save life, but also greatly reduce the probability of injury. Polin applied for a patent of a three -point V -type seat belt in 1958 (July 10, 1962, obtained the US No. 3043625 patent).
On August 13, 1959, the PV544 produced by Volvo Motors was the first car installed with a three -point V -type seat belt. By 1963, all Volvo cars from Sweden were equipped with three -point seat belts in the front seat, and used this as a standard configuration. Polin’s simple and secure design model has basically been used to this day. The American Land in the automotive industry is the place where the seat belt is the most looking down on the seat belt. In 1948, Ford Ford officially developed a seat belt. In 1949, some models of Nash cars appeared to choose a seat belt that could be installed. The survey of the year showed that some owners claimed that they had damaged the seat belt or cut off the seat belt with a blade. 48,000 Nash cars equipped with a seat belt were used, and only 1,000 vehicles used seat belts when driving. In 1955, a Ford car with a passenger seat belt was sold according to the user’s requirements. Unfortunately, there were few people who asked about it; the old things were repeated a few years later, and the results were still the same. Public opinion at that time criticized the safety belt to hinder the feet, making passengers feel uncomfortable and uncomfortable.
Despite March 31, 1955, Glenn W. Shern (1899-1984) in Michigan, Michigan, submitted a seat belt patent application, but she only obtained the US 2855215 patent until October 7, 1958. Compared with other patents, the invention is suitable for installation on all types of cars; installation is simple; the seat belt end connector is less damaged to the belt; its connector can be free to tease and prevent the seat belt from twisting or twists; fixed to fixed to The novel structural components in the car can evenly and safely disperse the impact to protect the safety of passengers and drivers. The initial reform of the three -point seat belt appeared in 1968. At that time, a small device named a fixed rotor was applied to the front seat belt, and the back seat was also adopted after 3 years. It was not until January 1, 1968 that the United States stipulated that all seats in front of the car had seat belts, and the car seat belt was commonly used since then. By 1975, most developed countries demanded that all cars must use seat belts. In November 1992, the Ministry of Public Security of China issued the “Notice on Driving and Small Bus Must use a seat belt”, which officially took effect on July 1, 1993. The notice stipulates that drivers and front row passengers on the road must use seat belts.
The contribution of the seat belt to the automotive industry is self -evident. It can be eliminated instantly in a simple way, so that the driver can enjoy driving pleasure. Because of the seat belt, the negative impact of the car has greatly reduced, and the engineers can rest assured to create a more motivated and faster car. The concept of the development and application of safety devices can be widely accepted as today as today.
“The car is really attractive. It not only directly improves people’s quality of life, but also has a great impact on the entire world.”
