Products knowledge

The clock spring is used to connect the main airbag (the one on the steering wheel) and the airbag wiring harness, which is actually a wiring harness. Because the main airbag has to rotate with the steering wheel, (it can be imagined as a wire harness with a certain length, wrapped around the steering shaft of the steering wheel, and can be loosened or tightened in a timely manner when the steering wheel is rotated, but it also has a limit , to ensure that the wire harness cannot be pulled off when the steering wheel is turned left or right to death) so the connecting wire harness must be left with a margin, and the steering wheel must be turned to the limit position to one side without being pulled off. This point needs special attention when installing, try to keep it in the middle position

Function In the event of a car collision, the airbag system is very effective in protecting the safety of drivers and passengers.

At present, the airbag system is generally a steering wheel single airbag system, or a dual airbag system. When a vehicle with dual airbags and seatbelt pretensioner systems is in a collision, regardless of the speed, the airbags and seatbelt pretensioners act at the same time, resulting in waste of airbags during low-speed collisions and a lot of increase in maintenance costs.

The double-action dual airbag system can automatically choose to use only the seat belt pretensioner, or the seat belt pretensioner and dual airbags to work at the same time according to the speed and acceleration of the car when the car collides. In this way, in the event of a low-speed collision, the system can sufficiently protect the occupants by using only seat belts, without wasting airbags. If a collision occurs at a speed greater than 30km/h, the seat belts and airbags act at the same time to protect the safety of drivers and passengers.

The safety of the car is divided into active safety and passive safety. Active safety refers to the ability of the car to prevent accidents, and passive safety refers to the ability of the car to protect the occupants in the event of an accident. When an automobile is involved in an accident, the injury to the occupants occurs in an instant. For example, in a head-on crash at 50 km/h, it takes only about a tenth of a second. In order to prevent injury to occupants in such a short period of time, safety equipment must be provided. At present, there are mainly seat belts, anti-collision body and airbag protection system (Supplemental Inflatable Restraint System, referred to as SRS) and so on.

Since many accidents are unavoidable, passive safety is also very important. As a research result of passive safety, airbags have been rapidly developed and popularized due to their convenient use, remarkable effects and low cost.

practice

Experiments and practice have proved that after the car is equipped with an airbag system, the degree of injury to the driver and occupants in a frontal collision accident of the car is greatly reduced. Some cars are not only equipped with front airbags, but also side airbags, which can also inflate the side airbags in the event of a side collision of the car, so as to reduce the injury in a side collision. The steering wheel of a car with an airbag device is usually no different from an ordinary steering wheel, but once a strong collision occurs at the front end of the car, the airbag will “pop” out of the steering wheel in an instant and cushion it between the steering wheel and the driver. Preventing the driver’s head and chest from hitting hard objects such as the steering wheel or dashboard, this wonderful device has saved many lives since its introduction. A research institute in the United States analyzed more than 7,000 car traffic accidents in the United States from 1985 to 1993 and found that the fatality rate of a car with an airbag device was reduced by 30% in the front of the car, and the death rate of the driver was reduced by 30%. Sedans are down 14 percent.
