AI Technical Summary
Technical Problem
Existing airbags offer reduced protection and support during repeated collisions, potentially causing multiple injuries to vehicle occupants.
Method used
An inner bladder is installed inside the airbag, with the inner and outer parts of the inner bladder divided into high-pressure and low-pressure zones. Gas is released from the high-pressure zone to the low-pressure zone through a one-way venting device, increasing the airbag's support and protection time.
Benefits of technology
The design of the inner bladder and one-way ventilation improves the protective effect of the airbag in the event of multiple collisions, and extends the time of support and protection for the human body.

Abstract
The utility model relates to the technical field of safety air bags, in particular to a self-adaptive safety air bag device which comprises an air bag body, an inner bag is installed in the air bag body and divides the interior of the air bag body into a high-pressure area and a low-pressure area, the interior of the inner bag is the high-pressure area, and the exterior of the inner bag is the low-pressure area. A plurality of air holes are formed in the side wall of the inner bag, and sealing structures are mounted in the air holes; the self-adaptive safety air bag device has the advantages that the inner bag is additionally arranged in the air bag, a large amount of gas is added into the inner bag, the pressure intensity of the gas in the inner bag is higher than that of the gas outside the inner bag, the gas in the inner bag can provide multi-layer support and protection for people in a vehicle, and the safety of the vehicle is improved. Meanwhile, the one-way ventilation piece can release internal gas into the air bag body, the gas exhausted from the interior of the air bag body is supplemented, and the time of supporting and protecting the human body by the air bag body is prolonged.
