Functions and introduction to the Airbag system The airbag can only be used as the auxiliary pro- tection device of the three-point safety belt, and it can play the auxiliary protection role in the event of an accident and the deceleration value of the vehicle is enough to trigger the airbag. Be- cause the airbag can only be triggered once and only in certain circumstances, and whether the airbag is triggered or not, the seat belt can pro- vide protection for the occupant in any situation. For example, in a pileup, only seat belts can pro- tect the occupants. Please refer to at the start of the chapter on page 37.
Airbags protect occupants in front and side crashes by slowing their movement in the direc- tion of impact. When an accident triggers the airbag, the system inflates the airbag through a gas generator. At this point, the airbag cover cracks and the airbag expands at high speed to cover the entire expan- sion area within milliseconds. Once the passen- ger wearing the seat belt begins to fall into the inflated airbag, the gas in the airbag immediately begins to escape under the pressure of the pas- senger's body and supports the passenger, slow- ing the inertial motion of the passenger and thereby reducing the risk of injury to the passen- ger.
Airbags may protect the occupant, but they can also cause other injuries, such as swelling, bruising and abrasions. The air bag also gener- ates friction heat when triggered. The airbag system is only one part of the passive safety system of the vehicle. Only when the vehi- cle occupants fasten their seat belts and sit cor- rectly can the airbag effectively play a protective role → page 28. The safety system of this vehicle is composed of equipment The safety system of this vehicle consists of the following safety equipment. Depending on the vehicle configuration, the model you purchase may not have certain safety equipment.
The most important factors affecting the trigger- ing of airbag are accident type, collision Angle, speed at the time of collision and the type of col- lision object. Therefore, even if the vehicle is ob- viously damaged, it does not mean that the air- bag should be triggered. – Front seat belt tightener. – Optimized three-point seatbelt for all seats. – Front seat belt tightening force limiter. – Seat belt alarm light . – Front passenger front airbag for seat ride iden- tification. – Front seat front airbag. Whether the airbag activates depends on the de- celeration of the vehicle at the time of impact and the deceleration reference value preset by the electronic control unit.
If the deceleration measured by the control unit during the collision is less than the baseline deceleration value preset by the control unit, the system will not trigger the airbag even if the vehicle is seriously dam- aged due to the collision. Therefore, the degree of damage to the vehicle, the cost of mainte- nance, and even the vehicle damage due to an accident cannot be used as indicators to deter- mine whether the airbag is triggered.
Due to the ever-changing environment of a vehicle when an accident occurs, it is impossible to specify a cer- tain range of vehicle speed and reference value that the airbag should trigger, so it cannot cover all types of collision accidents and the impact Angle that the airbag should trigger. In addition, there are other important factors affecting whether the airbag triggers, such as the charac- teristics of the collider (soft and hard), the Angle of impact, and the speed of the vehicle. – Left and right head airbags. – Front seat side airbag. – Airbag alarm/indicator lamp . – Control unit and sensor. – Optimized for safetyHighly adjustable head re- straints.
– Adjustable steering column. – Fixed point for child seat on the outside rear seat. – The top tether of the child seat retainer. The system will not activate the front, side, and head airbags if: – The collision velocity is below the required ref- erence value in the control unit – The ignition switch was off at the time of colli- sion. 182.5C1.TRO.74 – The vehicle deceleration measured by the con- trol unit is too low in frontal collision.
