Embodiment Construction

[0016] Below in conjunction with the accompanying drawings, the airbag door for covering the passenger side seamless airbag of the present invention is described in detail, so that the functions and characteristics of the present invention can be better understood.

[0017] Such as figure 1 and figure 2 As shown, the airbag door 1 of the present invention is installed on the skeleton 2 of the airbag deployment opening part on the instrument panel 6, and the airbag module (not shown) is arranged behind the deployment opening 11 of the instrument panel skeleton and is used on the edge of the deployment opening 11. Bolts (not shown) are fixed on the frame 2. The airbag door 1 includes a soft skin layer 3 , a foamed middle layer 4 and a soft material layer 5 as a reinforcing layer. In this embodiment, the soft material layer is nylon cloth. The nylon cloth is a high-density nylon cloth with a mesh structure of a certain thickness to ensure that the nylon cloth has sufficient st...

Abstract

The invention relates to an airbag door which covers a seamless type passenger-side airbag of an instrument board of an automobile. The airbag door is arranged at a spreading port of an airbag module of an instrument board framework, and comprises a surface layer, a middle foaming layer and a reinforcing layer from outside to inside in sequence; the reinforcing layer is soft material layers laminated together; the soft material layers are made of high-density nylon; and the airbag door is provided with a Y-type weakening line. When the airbag explodes, the airbag door is opened from the middle part along the weakening line; the surface of the instrument board is torn; the middle foaming layer is also torn; but a part of the nylon fabric layer connected with the instrument board framework is not turned over. As the nylon fabric layer replaces a traditional rigid reinforcing piece, the weight of the airbag door is greatly reduced; and the surface quality is high so as to reduce the opening force of the airbag door and not to damage windshield glass.

Description

technical field [0001] The present invention relates to an airbag door, in particular to a novel airbag door for covering a seamless passenger side airbag on an automobile instrument panel. Background technique [0002] At present, airbags are usually equipped on the occupant side of the dashboard, and more and more models are equipped with seamless airbags. Generally, the airbag cover is integrated with the dashboard, and there will be pre-installed airbags on the skin of the dashboard. The easily torn nick formed by weakening, when the airbag bursts, the pressure of the airbag bag body expands to tear the nick on the instrument panel, and the airbag cover opens. [0003] The commonly used seamless airbag doors are roughly divided into plastic airbag doors and metal airbag doors. The plastic airbag door is generally an H-shaped airbag door system in which a separate part of TPO material is welded to the frame of the instrument panel. Its advantage is that the technology i...
