Abstract

The invention discloses a tearing line structure of a safety air bag decoration cover. The tearing line structure comprises a face-shaped cover plate and a bending ring surrounding the side wall of the cover plate. A tearing line is arranged on a transition connecting part of the cover plate and the bending ring. A first strengthening block is arranged on the inner wall of the cover plate and provided with a first connecting hole. A second strengthening block is arranged on the inner wall of the bending ring and provided with a second connecting hole. A flyout preventing steel chain is connected between the first connecting hole and the second connecting hole. The tearing line structure has the beneficial effects that the tearing line of the air bag decoration cover avoids the middle portion of the cover plate, so that the situation that a sink mark is formed at the middle portion of the cover plate, and attractiveness is affected is avoided; and a safety air bag can be effectively popped up, and the cover plate can be prevented from causing hurt to people.

Description

Technical field [0001] The invention relates to the technical field of automobiles, in particular to a tear line structure of an airbag trim cover. Background technique [0002] The tear line of the car airbag trim cover is a commonly used structure in various airbag trim covers. The tear line is the thinnest structural line. The function is to tear along the tear line when the airbag is detonated, and the airbag pops up to protect the occupants. [0003] In the market, the current tear line structure is arranged in the middle of the cover. Such a structure is prone to sink marks during injection molding, and sink marks are formed in the middle of the cover, which easily affects the aesthetics of the decorative cover. In use, the sink marks will gradually deepen over time and affect the appearance. Summary of the invention [0004] The purpose of the present invention is to provide a tear line structure for an airbag trim cover, the tear line of the airbag trim cover avoids the mid...
