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 car airbag hinge mesh shown in the figure is composed of two mesh structure cloth areas 10, 20 and a hinge mesh cloth storage area 30. The hinge mesh cloth storage area 30 combines the two mesh structure cloth areas 10, 20 and 30. 20 to connect.

[0025] The car airbag hinge mesh is woven with two sets of warp yarns and weft yarns 60. One set of warp yarns in the two sets of warp yarns is high-strength yarn 40, such as: aramid yarn, polyester yarn, carbon fiber yarn, etc. The first choice is aramid yarn , The function of this group of warp yarns woven into cloth is to resist the huge pulling force generated by the opening of the shell when the airbag is exploded.

[0026] Corresponding to the high-strength warp yarns 40, the other group of yarns 50 is made of weaker-strength yarns as the base fabric warp...

Abstract

An automobile airbag hinge mesh cloth disclosed by the invention is composed of two mesh structure cloth areas and a hinge mesh cloth storage area, the hinge mesh cloth storage area connects the two mesh structure cloth areas, and the automobile airbag hinge The mesh is woven with two or more sets of warp yarns and weft yarns. Among the two or more sets of warp yarns, one set of warp yarns is high-strength yarns, and the rest of the warp yarns are weaker-strength yarns. The high-strength yarns are The other warp yarns participate in weaving together in the two mesh structure cloth areas. In the hinge mesh storage area, the remaining warp yarns do not participate in weaving. After the cloth woven with high-strength yarns is stored to a certain length, the remaining warp yarns pass through the machine and the fabric. Tighten the cloth of the corresponding layer in the storage area of ​​the hinged mesh cloth to form folds on the cloth surface. The storage area of ​​the hinge mesh cloth of the present invention is not in an unconstrained single fiber (yarn) state, but is stored in the form of woven cloth, so that its structure is stable, compact and can withstand greater tension.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an automobile airbag hinge mesh used for compounding the upper part of the automobile airbag with an injection molding 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] The car airbag is 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 up at a high speed, and the partially weakened plastic panel area will be opened under the action of a strong impact force. 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 open panel area needs to be controlled to expand to a certain extent and has a buffer. Open to facilitate the smooth pop-up o...
