[WapCar] Seat belt airbag is designed to avoid the injury of the seat belt, which can obviously reduce the injury of the seat belt to the torso and neck of the passenagers.
This technology is mainly to protect the torso of the rear passenagers in the event of an impact, because in the car, rear passenagers are not protected by frontal airbag like the front passenagers. In the event of an impact, it is also possible cause the injury due to huge inertial forward thrust, and the inflatable seat belt can better solve this problem.
In the event of an impact, the airbag in the seat belt pops ou to cushion forward torso thrust caused by inertia. At this time, the contact area between seat belt airbag and human body is increased by five times compared with that when the airbag is not deployed, which greatly increases the force area. Then the pressure on the body when the seat belt is restrained by the inertia of the torso is greatly reduce, and the secondary injury caused by the restraint of the seat belt is prevented.
This seat belt also has better protection for the children in the back row, the large inflatable bag in the event of a collision can more effectively reduce the risk of suffocation caused by the seat belt strangling the neck.
