Recently, some car owners uploaded videos on a short video platform that said that according to the Tesla crash test videos and other information he obtained, the overseas version of Tesla is equipped with knee airbags, so he wants to confirm whether domestic Teslas are also equipped with knee airbags. According to the owner, a blogger revealed to the riders that Tesla treats the safety equally regardless of the price and never "hands and feet" in the safety configuration. However, when the owner disassembled the baffle under the co-pilot 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 disassemble the baffle below, and the same was the case. In this regard, the owner joked that "this car may not be produced in the Shanghai factory, and I feel that my knees are so hard that I never use knee airbags." ”
To further confirm, the owner dialed the Tesla 400 customer service number. The other party said: Knee airbags do not affect the safety of the whole vehicle, when a car accident occurs, the role of knee airbags on the safety of the whole vehicle is not high, and all domestic Teslas are not equipped with knee airbags.
The knee airbags are deployed near the knee position below the center console to disperse the impact force across the passenger's legs in the event of an accident, thereby reducing leg injuries. By controlling the displacement of the legs, these airbags can also reduce secondary impacts on the abdomen and chest. However, according to the CONCLUSION OF IIHS IN THE UNITED STATES THROUGH CRASH TEST KNEE AIRBAGS, the probability of injury with and without knee balloons is 7.4% and 7.9%, and the difference between the two is very small. In addition, in low-speed collisions, the knee airbag pops out and is likely to cause damage to the knee. In other words, the US IIHS believes that the role of knee airbags on the safety of the whole vehicle is indeed not large, and even the disadvantages outweigh the benefits.
Are knee airbags useful? The answer is certainly yes, but the size of the role is highly influenced by the camp. In the inherent impression of consumers, the number of airbags seems to be more and more safe, when the vehicle has an accident, it can maximize the safety of the occupants in the car, but the position of the airbags is also very important, the current mainstream automotive products are basically equipped with main / passenger seat airbags, front / rear side airbags, front / rear head air curtains, etc., which can already effectively protect the occupants of 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 position, and the knee has more space, and in the event of an accident, the knee injury is not as large as expected.
In fact, in addition to Tesla, some models such as BMW 3 Series, Audi A4L, Mercedes-Benz E-Class and so on 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 models of different configurations. However, if only from the above-mentioned owner of the situation, since the knee airbag effect is not large, why the overseas version of the model is equipped with knee airbags, and the domestic model does not, then it can only be said that Tesla has more confidence in the safety performance of domestic models. If you only talk about knee air bags, do you think the role of knee air bags is really big? Welcome to discuss in the comments section.
