Automobile safety air bag hinge net cloth of warp knitting structure

Abstract

The invention discloses automobile safety air bag hinge net cloth of a warp knitting structure. The automobile safety air bag hinge net cloth consists of two net cloth regions and one fiber storage region connected with the two net cloth regions, wherein the fiber storage region is used as a hinging part. The automobile safety air bag hinge net cloth is characterized in that each of the two net cloth regions and the fiber storage region is completed by at least three groups of yarns by using a warp knitting process; the intensity of the first group of yarns is greater than the pulling force when an automobile air bag is opened through blasting; the intensity of the second group of yarns and the third group of yarns is smaller than the pulling force when the automobile safety air bag is opened through blasting; in the two net cloth regions, the second group of yarns, the third group of yarns and the first group of yarns are connected in a winding or hooking winding way at the connectorposition so as to form the required lattice region; in the fiber storage region, the first group of yarns form the storage of the first group of yarns through the continuous transverse movement. The automobile safety air bag hinge net cloth of the warp knitting structure changes the conditions that at the single fiber looped storage region form in the existing hinge net cloth, the fiber material is not limited, and the net cloth structures in other forms are instable.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a warp-knitted automobile airbag hinge mesh. 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] The airbag is generally placed under the plastic panel of the car, and the corresponding car plastic panel and the plastic body of the car will be partially weakened. When the airbag is triggered, it will be inflated rapidly and ejected at a high speed. The bottom breaks, allowing the car's plastic panel to open. In the process of opening the plastic panel of the car, the plastic panel of the car may be broken, and these fragments will bring great harm to the human body. [0004] In order to prevent this from happening, the simultaneously opened automotive plastic panel needs to be expanded to a certain extent in a controlled manner and opened with a buffer to ...

AI Technical Summary

Problems solved by technology

[0008] For the products on the market, the fiber storage area is realized by fiber loops or folds, but the fiber loops or folds are relatively loose in structure, and the shape is unstable during weaving, subsequent processing and installation, and is easy to hook. Hanging, inconvenient to operate (see Figure 5 )
