Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] see Figure 1 to Figure 3 , the automobile airbag hinge mesh cloth shown in the figure is made up of two mesh structure cloth areas 10,20 and a hinge mesh cloth storage area 30, and the hinge mesh cloth storage area 30 combines the two mesh structure cloth areas 10, 20 connected.

[0025] Automobile airbag hinge mesh is woven with two sets of warp yarns and weft yarns 60, and one of the two sets of warp yarns is high-strength yarn 40, such as: aramid yarn, polyester yarn, carbon fiber yarn, etc. Aramid yarn is the first choice , the role of this group of warp yarns to make cloth is to resist the huge tension generated by the opening of the shell when the airbag bursts.

[0026] Corresponding to the high-strength warp yarn 40, the material of another group of yarns 50 is a yarn with weaker strength as the base fabric warp yarn. When the...

Abstract

The invention discloses an automobile air bag hinge screen cloth. The screen cloth is composed of two mesh structure cloth regions and one hinge screen cloth storage region. The two mesh structure cloth regions are connected through the hinge screen cloth storage region. The automobile air bag hinge screen cloth is formed by knitting two or more sets of warp and weft. One set of warp in the two ormore sets of warp is high-strength yarn, the other warp is low-strength yarn, the high-strength yarn and the other warp are knitted together within the two mesh structure cloth regions, the other warp in the hinge screen cloth storage region is not knitted, after a cloth knitted by the high-strength yarn is stored for a certain length, the other warp tightens a cloth at the corresponding layer within the hinge screen cloth storage region through the machines and fabric technologies, and cloth covers are folded. The hinge screen cloth storage region is stored in the knitted cloth state insteadof the independent single-fiber (yarn) state, the structure is stable and compact, and larger tension can be borne.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an automobile airbag hinge mesh cloth used for compounding the top of the automobile airbag with an injection molded shell. Background technique [0002] Car airbags are an important component to ensure the safety of vehicle occupants, and can play a protective role when a car collides. [0003] Car airbags are generally placed under the plastic panel of the car, and the corresponding plastic parts will be partially weakened. When the airbag is triggered, it will pop out at high speed, and the partially weakened plastic panel area will open under the action of a strong impact. The plastic panel may be broken during the process. It is obvious that these fragments will bring great harm to the human body. In order to prevent this from happening, the area of ​​the opened panel needs to be expanded to a certain extent in a controlled manner and buffered. Open it to facilitate the smooth eje...
