Description

Technical field [0001] The invention belongs to the technical field of automobile safety, and specifically relates to an active safety seat. Background technique [0002] According to statistics, an average of more than 300 people died in car accidents every day in 2016, and the actual number of deaths may be far greater than the statistics. Today's car seats, due to various reasons such as technology or cost, have low safety configurations for low-profile vehicles. Generally, they are only equipped with airbags to increase the safety factor. The active and passive safety factors are often not high. In this case, once a vehicle collision occurs, it will often cause immeasurable consequences. [0003] When a car is hit from the front, the occupant will hit the front trim at the first time due to the impact force. Due to the limited collision space, the occupant will often suffer great damage; when the car is hit by the rear, it will The impact force is the first time that the occ...

AI Technical Summary

Problems solved by technology

During the entire impact process, the occupant's neck bears a huge impact, which in turn causes serious injury

Although the existing safety seats can properly reduce occupant injuries, they are all single protection devices, the protection is not comprehensive enough, the structure is large and complex, and there is still a lot of room for improvement

[0004] In addition, because occupants sometimes lead to irregular and diverse sitting postures in pursuit of a comfortable sitting posture, when a collision occurs, the occupant's body often dives, and it will cause great damage to the occupant's abdomen
