Airbag spring - Connects the main airbag to the airbag harness
The clock spring is used to connect the main airbag (the one on the steering wheel) to the airbag harness, which is basically a piece of wire harness. Because the main air bag should rotate with the steering wheel, (it can be imagined as a wire harness with a certain length, wrapped around the steering wheel steering shaft, when rotating with the steering wheel, it can be reversed or wound more tightly, but it also has a limit, to ensure that the steering wheel to the left or right, the wire harness can not be pulled off), so the connecting wire harness should leave a margin. Make sure the steering wheel turns to the side to the limit position without being pulled off. This point in the installation is special attention, as far as possible to ensure that it is in the middle position.
Product introduction
In the event of a car crash, the airbag system is very effective in keeping the driver and passenger safe.
At present, the airbag system is generally a single airbag system of the steering wheel, or a double airbag system. When a vehicle equipped with dual airbags and seat belt pretensioner system crashes, regardless of the speed, the airbags and seat belt pretensioner operate at the same time, resulting in the waste of airbags during low-speed crashes, which increases the maintenance cost a lot.
The two-action dual airbag system, in the event of a crash, can automatically choose to use only the seat belt pretensioner or the seat belt pretensioner and the dual airbag at the same time according to the speed and acceleration of the car. In this way, in the event of a crash at low speed, the system can only use seat belts to protect the driver and passenger safety, without wasting air bags. If the speed is greater than 30km/h in the crash, the seat belt and air bag action at the same time, in order to protect the safety of the driver and passenger.
Instructions for use
The airbag system can increase the safety protection of the passengers in the car, but the premise is that the airbag system must be correctly understood and used.
Must be used with a seat belt
If a seat belt is not fastened, even with air bags, it can cause serious injury or even death in a crash. In the event of a crash, the seat belt reduces the risk of you hitting objects in the car or being thrown out of the vehicle. Air bags are designed to work in conjunction with the seat belt, not to replace it. Only in a moderate to severe frontal collision can the air bag inflate. It does not bulge during rollover and rear end collisions, or in low speed frontal collisions, or in most side collisions. All passengers in a car should wear a seat belt, regardless of whether their seat has an airbag or not.
Keep a good distance from the airbag
When the air bag expands, it explodes with great force and in less than the blink of an eye. If you get too close to the air bag, such as leaning forward, you can get serious injury. A seat belt can hold you in place before and during a crash. Therefore, even if there is an airbag, always wear a seat belt. And the driver should sit as far back as possible under the premise of ensuring that he can control the vehicle.
Air bags are not designed for children
Air bags and three-point seat belts provide optimal protection for adults, but they do not protect children and infants. Car seat belts and air bag systems are not designed for children and infants, who need to be protected with child seats.
Airbag indicator light
There is an airbag-shaped "airbag ready light" on the dashboard. This indicator indicates whether the electrical system of the airbag is faulty. When starting the engine, it will light up briefly, but it should be extinguished quickly. If the light is always on or blinking during driving, it means that the airbag system is faulty and should be repaired to the maintenance station as soon as possible.
Where are the airbags
The air bag in the driver's seat is in the center of the steering wheel.
The passenger airbag is in the right dashboard.
Note: If there is an object between the occupant and the airbag, the airbag may not expand properly, or it may strike the occupant, resulting in serious injury or death. Therefore, there must be nothing in the space where the airbag is inflated, and never place anything on the steering wheel or near the airbag cover.
When should the airbag inflate
The front airbags of the driver and co-pilot inflate during a moderate to severe frontal collision or near frontal collision, but, by design, the airbags can only inflate when the impact force exceeds a pre-set limit. This limit describes the severity of a crash when the airbag expands and is set taking into account a number of scenarios. Whether the airbag expands does not depend on the speed of the vehicle, but mainly depends on the collision object, the direction of the collision and the deceleration of the car.
If your car hits a stationary, hard wall head-on, the limit is about 14 to 27km/h (different vehicle limits may vary slightly).
The airbag may expand at different collision speeds due to the following factors:
Whether the colliding object is stationary or moving. Whether the colliding object is prone to deformation. How wide (such as a wall) or narrow (such as a pillar) the collision object is. The Angle of the collision.
The front airbag does not inflate when the vehicle rolls over, in a rear collision, or in most side collisions, because in these cases the front airbag does not inflate to protect the passenger.
In any crash, it is not only based on the degree of damage to the vehicle or the cost of maintenance to determine whether the air bag should be deployed. For a frontal or near-frontal crash, the inflating of the airbag depends on the Angle of impact and the deceleration of the car.
The airbag system works well in most driving conditions, including off-road driving. However, be sure to maintain a safe speed at all times, especially on uneven roads. Also, be sure to wear your seat belt.
The airbag should be used in conjunction with the seat belt
Since the airbag works through an explosion, and the designer is often looking for the best solution from the majority of normal crash simulation tests, but in life, every driver has his own driving habits, which causes people and the airbag will have a different position relationship, which determines the instability of the airbag work. Therefore, to ensure that the airbag really plays a safe role, the driver and passenger must develop good driving habits to ensure that the chest and the steering wheel maintain a certain distance. The most effective measure is to fasten the seat belt, and the airbag is only an auxiliary safety system, which needs to be used with the seat belt to maximize the safety protection effect.
