Problems solved by technology

However, it uses thinning elements spaced at intervals in the foam layer to control the breakage of the foam, which is complex to manufacture and requires additional material, which is costly
In addition, this airbag mask can only roughly control the breaking position of the foam layer, but cannot accurately control the first breaking point of the foam, so its control effect is still not optimal.

Abstract

An airbag covering comprises a side wall (2) defining an airbag firing channel, an airbag flap (3) covering the airbag firing channel, a foam layer (4) covered onto the outer side of the airbag flap (3), a skin layer (5) covered onto the foam layer (4), and a support (6) supporting the foam layer (4). A weakening structure is formed in the intersection of the airbag flap (3) and the side wall (2) and the support (6). Said airbag flap (3) further comprises an additional weakening structure abutting against said weakening structure, so that when the airbag is to deploy, the additional weakening structure of the airbag flap (3) is broken firstly to release the airbag. The airbag covering has the advantages of ease of manufacture, being able to control the first breaking point of the foam layer (4), decreasing the foaming splash area and splash risk.

Description

technical field [0001] The present invention relates to an airbag cover, and more particularly, to an airbag cover mounted on a dashboard or a steering wheel of a vehicle. Background technique [0002] The airbag is usually installed in the instrument panel or steering wheel of the vehicle, and is deployed when the vehicle is impacted to protect the safety of passengers. When the airbag is not deployed, it is covered by the airbag cover in the airbag detonation channel of the instrument panel or the steering wheel of the vehicle. [0003] The airbag cover includes an airbag flap, the airbag flap is covered with a foam layer made of foam, used to cover the airbag detonation channel containing the airbag, when the airbag is deployed, the airbag flap and the foam layer are broken together, so that the airbag can be deployed quickly to the outside of the vehicle's dashboard or steering wheel, thereby protecting the occupant's body and head in the event of a vehicle impact.
