Technical Field

The invention relates to an airbag with a variable ejection volume.

Background

When collision occurs, the vehicle controller ACU judges the collision degree through the sensor and the microprocessor and transmits a signal to the ACU controller, and the ACU controller gives a generator through the collision degree signal and forms a soft air cushion through inflation to play a role in buffering and absorbing energy so as to reduce the injury degree of passengers. Since the vehicle is not completely frontal collided when the vehicle is collided, there is an offset collision, and when the vehicle is collided with offset, the airbag modules (DAB, PAB) and the side curtain modules (CAB) on the vehicle are unfolded, but the upper body of the human body can generate lateral deviation under the action of collision lateral force, and the head of the human body can not be completely protected after the normal air bag module and the side air curtain are unfolded, the reason for this is that typical airbag modules and side curtain deployments do not completely fill the entire head contact area, a certain gap exists between the air bag module and the side air curtain, and the head of a human body possibly passes through the gap to be hit on the door panel or the A column during offset collision, the safety airbag module can fully protect passengers on the vehicle by filling a gap between the safety airbag module and the passenger in time, reduce the damage of the passengers during offset collision, and further reduce the damage degree of the passengers on the vehicle.
