Problems solved by technology

However, since the reinforcement layers have roughly the same shape, it is difficult to identify which side of the reinforcement layer has a thermal barrier coating and which side does not have a thermal barrier coating when laying
Once the identification is wrong, the reinforcement layer will probably not be able to achieve the heat insulation protection effect of the identification
This requires careful manual identification by laying personnel, which undoubtedly increases the labor intensity of assembly and greatly reduces assembly efficiency

Embodiment Construction

[0020] In the following, the same reference numerals refer to the same elements.

[0021] As mentioned in "Background Technology", an automobile airbag generally includes an airbag, a gas generator, a support ring and a housing for accommodating the aforementioned components. The air bag and the gas generator are fixed on the bottom wall of the housing through the support ring. figure 1 A structural schematic diagram of an automobile airbag specially used for the driver's seat is shown.

[0022] Such as figure 1 As shown, the airbag M is installed on the hub B in the center of the steering wheel W. The airbag M includes a case 4, an air bag 11 folded and housed in the case 4, a gas generator 7 that supplies inflation gas to the air bag 11 and is also housed in the case 4, and covers and installs the air bag 11. The airbag cover 6 on the casing 4 and the support ring 8 for fixing the end of the airbag 11 are provided.

[0023] The gas generator 7 is fixed on the bottom wall...

Abstract

The invention provides an automotive safety airbag comprising multiple reinforcing layers. The reinforcing layers are all formed by one piece of cloth. The invention further provides a production method for the reinforcing layers. Through tailoring, overturning and bending of each section of the cloth, all coatings in the reinforcing layers are ensured to face the same side, and two adjacent reinforcing layers are connected through a section of connecting portion, so that the reinforcing layers are prevented from shedding; through corresponding arrangement on the cloth, any number of the reinforcing layers can be conveniently selected, so that mounting of the reinforcing layers is realized conveniently.

Description

technical field [0001] The invention relates to an automobile safety airbag, more specifically, to an automobile safety airbag with a reinforcement layer, and in addition, the invention also relates to a method for manufacturing the reinforcement layer of the automobile safety airbag. Background technique [0002] Existing automotive airbags generally include an airbag, a gas generator, a support ring and a housing for accommodating the aforementioned components. The air bag and the gas generator are fixed on the bottom wall of the housing through the support ring. When the vehicle has an emergency collision, the collision sensor activates the gas generator to generate inflation gas to inflate the airbag, thereby deploying the airbag to protect the vehicle occupants (such as the driver and / or passengers). [0003] The expansion gas produced by the gas generator often has high temperature and high pressure. When the inflation gas blows to a specific part of the airbag perip...
