1:What are they for?
Knee airbags are deployed during a collision to primarily prevent direct impact between the knees and the interior panels for both drivers and passengers.
2:Did you know?
The distance between the knees and the center console is the shortest, making it a vulnerable area prone to fractures and injuries, which calls for protection. Knee airbags are positioned in front of the seats.
Seat belts and airbags form a complete safety system. Airbags serve as a supplementary feature to seat belts, so wearing seat belts is a prerequisite.
Depending solely on the airbag does not guarantee absolute safety, nor does it provide a comfortable and soft feeling. Injuries can still occur, and they may even be more severe.
Airbags do not always deploy in every collision. If the impact does not reach the airbag's activation point or does not meet the necessary criteria for deployment, the airbag will not inflate.
Airbags may not always be effective. When passengers deviate from their seats or when children are seated, the airbag system may not provide the intended protection and can potentially cause harm to occupants. Additionally, in low-speed collisions, occupants and drivers who are wearing seat belts are adequately protected, and the deployment of airbags is unnecessary and may even exacerbate the injuries caused by the collision.
If the airbag warning light on the instrument panel remains illuminated, it indicates a possible malfunction, and you should have it checked and repaired.
3:Technical Principles
Knee airbags consist of three main components: the airbag, sensors, and inflation system. When the sensors detect a collision, the inflation system rapidly fills the airbag with harmless nitrogen gas or releases compressed nitrogen to inflate the airbag within a fraction of a second. This helps protect occupants from the impact forces generated by the collision. After approximately one second, the airbag begins to deflate through vent holes, allowing occupants to move without obstruction.
