Description

Technical Field

[0001] This utility model belongs to the field of cover structure, specifically relating to an airbag cover. Background Technology

[0002] The existing airbag cover is fastened to the top of the steering wheel assembly. The back of the airbag cover has a welding area with multiple welded components extending downwards from the back. Due to the height difference between the welded components and the back of the airbag cover, during deployment, the airbag enters this area with the thickness difference, increasing the contact area and friction. This causes the airbag to scrape against the welded area, ultimately resulting in defects such as excessive tearing or breakage of the cover. Summary of the Invention
