Problems solved by technology

[0007] However, there is a problem that when the airbag cover is torn and opened, debris and the like are scattered from the portion of the airbag cover adjacent to the cut line and may cause injury to the user
[0013] However, in the construction of the fabric sheet introduced in U.S. Patent No. 8,348,303, the stop warp yarns used to support the load can be pulled apart by the explosion pressure of the airbag
If the stop warp threads are pulled, they cannot be used as a hinge for the airbag cover, whereby the airbag cover may separate from its original position and unravel outwards

Abstract

The present invention provides a hinge device for an airbag cover of a vehicle. In a specific embodiment, the fabric sheet is formed by weaving warp and weft yarns in a plurality of grid spaces, and the fabric sheet is integrally formed on the inner surface of the airbag cover. The grid spaces formed in the opposite ends of the fabric sheet that rotate when the airbag cover is opened by deployment of the airbag are arranged in a compressed state so as to be expandable.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority from Korean Patent Application No. 10-2016-0128792 filed on October 6, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to a hinge device for an airbag door of a vehicle. Background technique [0004] Generally, an airbag module for a vehicle includes an airbag module for a driver's seat installed in a steering wheel and an airbag module for a passenger seat installed in an instrument panel in front of a passenger seat. [0005] Generally, an airbag module is installed to be covered with an airbag cover in consideration of appearance. Cutting lines such as wire grooves are formed in the inner surface or the outer surface of such an airbag cover. [0006] Therefore, when the airbag of the airbag module is deployed, the airbag cover is torn along the cut line and opened in two directions. [...
