1：What is it?
General airbag deflation technology involves the placement of additional variable exhaust ports on the backside of the airbag, controlled by a restraint system composed of flexible covers and soft tether connections. When a passenger exerts pressure on the airbag, the variable exhaust ports are opened, allowing for rapid deflation of the airbag. This reduces the risk of injury to passengers caused by the inflation of the safety airbag.
2：Did you know?
This technology can be applied to single-stage airbags.
Compared to dual-stage airbags, it offers smaller size, simpler structure, and lower cost.
3：Principle:
Additional variable exhaust ports are placed on the backside of the airbag, covered by flexible covers. The flexible covers are connected to an internal restraint system through soft tether connections for control. During the inflation phase, the internal restraint system keeps the flexible covers tightly sealed over the variable exhaust ports, preventing premature deflation of the airbag. When a passenger exerts pressure on the safety airbag due to inertia, the traditional airbag deflation system is activated. Simultaneously, the internal restraint system is relaxed, opening the flexible exhaust port cover and allowing for rapid deflation of the airbag. This reduces the risk of injury to passengers caused by the inflation of the safety airbag.

Dual-Stage Airbags:
In the event of a collision, if the occupants have a small body size or are positioned closer to the steering wheel, the system triggers only the first-stage igniter, resulting in partial inflation of the airbag. This reduces the likelihood of injury for smaller-sized occupants. If the occupant's body size and seating position require maximum protection, the system triggers the second-stage igniter for full inflation of the airbag.
