[0001] The utility model relates to the technical field of automobile parts, in particular to a safety airbag assembly and an automobile. Background Art

[0002] With the continuous improvement of market demand, the interior styling of motor vehicles is also changing with the demand. The instrument panel styling is developing rapidly to adapt to new demands, and the demand for large screens on the co-driver side is increasing. The traditional frontal airbag for the co-driver is arranged inside the instrument panel in front of the co-driver. The instrument panel, the car cross beam (abbreviation: CCB) of the passenger car, the front windshield, etc. have relatively high restrictions on its layout, and it no longer meets the styling requirements.

[0003] In order to balance the instrument panel styling and the safety of occupant protection, as an important auxiliary protection device for the co-driver, the overhead airbag is directly arranged in the front row headliner. Its deployment has a great impact on the front windshield and the front cross beam. The front cross beam is prone to deformation. After the front cross beam is deformed, on the one hand, there may be a situation where the airbag is punctured, and it cannot provide effective protection for the co-driver. On the other hand, it is easy to break the front windshield, posing a safety hazard to the co-driver. Summary of the Utility Model
