AutoBeta(AutoBeta.net)01/09 Report--

Recently, a car owner uploaded a video on a short video platform, saying that according to the Tesla collision test video and other information he obtained, the overseas version of Tesla was equipped with knee airbags. Therefore, I want to confirm whether domestic Tesla is also equipped with knee airbags. According to the car owner, a blogger revealed to car users that Tesla never "tampered" with the security configuration, regardless of the price. However, when the owner opened the bezel under the co-driver and found that there was not a knee airbag, only a plastic cover, the owner had a glimmer of hope to return to the main driver to open the bezel below. In this regard, the car owner joked that "this car may not be made in Shanghai factory, and feel that their knees are so hard that they never use knee airbags."

In order to further confirm, the car owner dialed Tesla 400 customer service number. The other party said: knee airbags do not affect the safety of the whole vehicle, the effect of knee airbags on the safety of the whole vehicle is not high in the event of a car accident, and all domestic Tesla are not equipped with knee airbags.

The knee airbag is deployed from the position under the center console near the knee in order to spread the impact force on the passengers' legs in the event of an accident, thereby reducing leg injury. By controlling the displacement of the legs, these airbags can also reduce the secondary impact on the abdomen and chest. However, according to the IIHS of the United States, through the collision test of knee airbags, the probability of injury with and without knee airbags is 7.4% and 7.9%, and the difference between them is very small. In addition, in a low-speed collision, the knee airbag pops up easily to cause injury to the knee. In other words, the IIHS of the United States believes that the knee airbag does not have much effect on the safety of the whole vehicle, or even does more harm than good.

Is the knee airbag useful or not? The answer must be yes, but the size of the role is subject to the camp. In the inherent impression of consumers, the more the number of airbags, the safer the car occupants, but the location of the airbags is also very important. at present, mainstream automotive products are basically equipped with main / passenger seat airbags, front / rear side airbags, front / rear head air curtains, etc., which can effectively protect the occupants in the car to ensure safety. In contrast, the knee airbag is designed to protect the occupant's knee, but in fact the occupant is closer to the steering wheel, and the knee has more space, and the knee injury is not as serious as expected in the event of an accident.

In fact, in addition to Tesla, such as the BMW 3-Series, Audi A4L, Mercedes-Benz E-Class and other models are not equipped with knee airbags. In fact, for automotive products, active safety configuration and passive safety configuration are very important, and the number of airbags is often matched according to different configurations of different models. However, if only from the situation described by the above owners, since the knee airbag is not very useful, why overseas models are equipped with knee airbag, while domestic models do not, then Tesla can only say that he has more confidence in the safety performance of domestic models. If the knee airbag alone is concerned, do you think the effect of the knee airbag is very small? Welcome to discuss it in the comments section.
