How to remove the 18 A4L airbags

1. Wear fireproof gloves and protective goggles;

2. Disassemble the covers on both sides of the steering wheel;

3. Unscrew the 4 fixing bolts on both sides;

4 Carefully remove the airbag assembly;

5 Use a small screwdriver to turn the black plastic cleats outward, and carefully rotate the generator counterclockwise until the generator - the sensor seat is aligned with the steering wheel matching slot. Gently remove the generator-sensor from the steering wheel interface.

6. Turn the front wheel to the position in front of you, if you still need to continue to use the steering column and steering wheel, you should mark the relative position of the steering wheel and the steering direction, and then remove the fixing nut of the steering wheel, remove the nut and flat washer, and remove the steering wheel. Before installing the airbag, care should be taken: Wear fireproof gloves and protective goggles.

Car airbags cannot be manually opened in the normal way. And there are safety hazards.

Automotive airbag systems can be divided into 3 components:

gas generators;

control systems; Gasbag.

The inflator is used to produce a sufficient volume of gas at a fast enough rate to feed the air bag. The control system is used to determine the severity of the collision, decide whether the airbag should be opened, and start the inflator when the conditions are met. The airbag is used to accept the gas from the inflator, control the pressure of the gas and the position and shape of the space occupied by the airbag, and accept the collision of the occupants, absorb the kinetic energy of the collision, thereby achieve the purpose of reducing and reducing the occupants.

After a collision, the airbag is triggered by a collision sensor and an airbag control computer.

1. Modern cars usually have three collision sensors, one under the left and right fenders, and the other is called ** collision sensor, which is located on the control computer. Some cars are also equipped with deceleration sensors to monitor the severity of the crash and allow the computer to determine whether the airbag needs to be triggered.

2. In the event of a collision, the direction of the collision must be within 30 degrees of the longitudinal axis of the car, otherwise the front airbag will not be triggered.

3. After the collision, the collision sensor is triggered, and the signal is transmitted to the computer, and the computer determines that the airbag needs to be triggered to protect the safety of the front occupants, so the airbag detonator circuit is turned on, and the detonator is decomposed, and a large amount of nitrogen is rushed into the airbag, so that the airbag is inflated, and the head of the occupant is blocked due to inertia after the collision, so as to protect the occupants from the injury of cervical spine breakage.

The main airbag is in the steering wheel, and the auxiliary airbag is in the center console of the co-pilot, as shown below

Airbag system is a passive safety protection system that works in conjunction with seat belts to provide effective collision protection for occupants. In the event of a car collision, car airbags can reduce the rate of head injuries by 25% and the rate of facial injuries by about 80%.

The airbag was first proposed by Hetrick in August 1953 and obtained the patent of "automobile cushion safety device" in the United States. With the formulation of vehicle safety standards in various countries, the equipment rate of airbags is getting higher and higher. The airbag installation rate in Europe, the United States, Japan and other countries has reached nearly 100%.

The airbags are located in the front (front and passenger seats), side (front and rear seats) and roof. The words Supp Le mentalinflatabler es traintsystem, or SRS for short, are printed on the outside of the container equipped with the airbag system, which literally translates into Chinese and should be "auxiliary inflatable restraint system". It is designed to reduce the degree of injury caused by inertia in the event of a secondary collision with the occupants after a car collision.

An airbag system is called an SRS, and an airbag is just a secondary protection device relative to a seat belt.

The airbag is made of a special fabric nylon with a rubber lining, which is filled with harmless helium when working. This system is activated by a sensor that monitors how small the car's airbag is in a collision. In the early stages of a crash, the airbag begins to inflate, and it takes about a second to inflate safely.

Summary. Hello, dear. We're happy to answer your <>

Dismantle the original car airbag, the original airbag hairspring of the car is compared as follows, the two steering wheels and airbags, the original car is on the left, and the German-made TTRS is on the right. I have to say that the workmanship and materials of the steering wheel of the TTRS are really amazing. Put on a new plate and put it on.

Fortunately, my sports version of the original car is equipped with paddle shifters, which are multi-functional, so the master said that it can be installed in situ without changing needles. Tighten these two screws and you're done. <>

Kiss, Audi A4L car steering wheel grip: If you think of the steering wheel as a clock dial face, the correct gesture is to hold it with your left hand.

Between nine and ten o'clock, the right hand is held.

Between the third and fourth o'clock, in the event of a collision, such a posture is more conducive to supporting the body. If you hold the steering wheel with only four fingers and stick your thumb to the steering wheel, when the wheel hits a stone or a high step, the front wheel will sometimes suddenly turn to one side, causing the steering wheel to rotate quickly, and it is possible to discount your thumb. <>

I mean I want to use the airbag of the original car to install it on the steering wheel of the 2019 model year, the original car is four corners, I see that the base is different, I want to consult, can it be installed? What needs to be changed?

Dear, this can't be installed, and it can't be modified at the moment, sorry

How to replace the seat belt Audi A4L How to replace the seat belt, first remove the induction line of the safety buckle, then remove the airbag, find the place where the seat belt is bolted, remove the seat belt buckle without regret, and then remove the induction key. Install the new buckle to the seat, then to the car seat, install the new retractor, tighten it with a wrench, and finally check that the seat belt is working properly. In the automobile seat belt system, the seat belt is connected to the retractor, and the core component of the retractor is the reel, which is connected to one end of the seat belt.

Inside the retractor, the spring provides a rotational force to the reel, which will rotate the reel to roll up any loose harness. When the harness is pulled out, the reel will rotate counterclockwise and the connected springs will also rotate in the same direction. In this way, the rotating reel reverses the spring.

Replacement of car seat belts:1. The coil inside the seat belt is aging, resulting in the seat belt being too loose or not tightened in time.

If the seat belt is not replaced, in an emergency, if the seat belt is too loose, it can easily cause the passenger to slide out of the seat belt, causing serious injury. 2.Seat belts are subjected to a lot of tensile loads in use.

Even if it is not damaged, it should be replaced and can no longer be used. 3.There was a collision in the car that caused the airbag to deploy** and the seat belt had to be replaced in a timely manner.

Millions of car purchase subsidies.
