Abstract
The invention discloses an automobile safety airbag, an automobile safety airbag and a vehicle, which comprise an airbag body, wherein a glue coating layer is additionally arranged between two pieces of woven cloth which are opposite to each other at the part of the airbag body, when the airbag body is inflated, the part of the airbag body which is not provided with the glue coating layer is unfolded, and when the gas pressure in the airbag body reaches the unfolding threshold value of the glue coating layer, the woven cloth and the glue coating layer of the airbag body are separated and responded, so that the airbag body is unfolded at the part arranged on the glue coating layer. The invention can control the sequence of the expansion of each part of the airbag.
Description
Technical Field
The invention belongs to the technical field of automobile safety airbags, and particularly relates to an air bag of an automobile safety airbag, the automobile safety airbag and a vehicle.
Background
The automobile safety air bag mainly comprises a gas generator, a shell, an air bag and the like. When a collision safety accident occurs, the gas generator generates gas to inflate the air bag, and when a certain pressure is reached, the air bag breaks through the shell and is completely unfolded to buffer the impact injury of the collision to drivers and passengers.
However, the conventional airbag is mainly folded and processed at a certain temperature and pressure for a certain time, so that the folded airbag maintains a shape, thereby ensuring that the airbag is completely unfolded. However, this method of folding does not allow for control over the sequence of deployment of the various portions of the airbag, particularly for complex shaped airbags. In addition, the existing methods of folding the airbag do not guarantee complete deployment in the event of a crash.
Therefore, there is a need for developing an automotive airbag bag, an automotive airbag, and a vehicle.
Disclosure of Invention
The invention aims to provide an automobile safety airbag bag, an automobile safety airbag and a vehicle, which can control the sequence of the expansion of each part of the airbag bag.
In a first aspect, the automobile safety airbag comprises an airbag body, wherein a glue coating layer is additionally arranged between two woven fabrics which are opposite to each other at the part of the airbag body, when the airbag body is inflated, the part of the airbag body, which is not provided with the glue coating layer, is unfolded, and when the gas pressure in the airbag body reaches the unfolding threshold value of the glue coating layer, the woven fabrics and the glue coating layer of the airbag body are separated and responded, so that the airbag body is unfolded at the part arranged on the glue coating layer.
Optionally, the airbag body is provided with glue coating layers with different unfolding thresholds according to the unfolding sequence of different parts, and the unfolding threshold of the glue coating layer of the first unfolding part is smaller than that of the glue coating layer of the second unfolding part.
In a second aspect, the invention provides an automobile airbag, which uses the airbag of the automobile airbag.
In a third aspect, a vehicle according to the present invention employs an automotive airbag according to the present invention.
The invention has the following advantages:
(1) the gluing layer is added between two layers of weaving opposite to the part of the airbag of the safety airbag, and when gas generated by the gas generator enters the airbag of the airbag, the part of the airbag, which is not added with the gluing layer, is firstly inflated. When the gas pressure in the airbag reaches the unfolding threshold value of the glue coating layer, the woven fabric and the glue coating layer of the airbag are separated, and the woven fabric and the glue coating part of the airbag are expanded and unfolded, so that the aim of controlling the unfolding sequence of all parts of the airbag is fulfilled, and meanwhile, the airbag can be completely unfolded.
(2) By adding the glue coating layers with different unfolding thresholds at different parts of the air bag, the unfolding motion track of the air bag can be controlled, so that the application of the air bag with the complex shape in the field of automobile collision safety of the air bag of the safety air bag is realized.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1 to 4, in the present embodiment, an airbag for an automotive airbag includes an airbag body, and a glue coating layer 2 is additionally provided between two woven fabrics 1 facing each other at a portion of the airbag body. When the airbag air bag body is inflated through the gas generator 3, the part of the airbag air bag body, which is not provided with the glue coating layer 2, is unfolded, and when the gas pressure in the airbag air bag body reaches the unfolding threshold value of the glue coating layer 2, the woven cloth 1 of the airbag air bag body and the glue coating layer 2 are separated to respond, so that the airbag air bag body is unfolded at the part of the glue coating layer 2. Therefore, the running track of the air bag of the automobile safety air bag is changed, and the air bag of the automobile safety air bag with an irregular geometric shape can be applied.
As shown in fig. 3 and 4, in this embodiment, the order of the portions of the airbag body can be controlled, and particularly, for the airbag body with a complicated shape, the airbag body with a complicated shape can be sufficiently deployed by controlling the order of the portions of the airbag body. The specific mode adopted in the embodiment is as follows: arranging the rubber coating layers 2 with different unfolding thresholds on the airbag body according to the unfolding sequence of different parts, wherein the unfolding threshold of the rubber coating layer 2 of the first unfolding part is smaller than that of the rubber coating layer 2 of the later unfolding part.
In this embodiment, the airbag of the airbag for the vehicle as described in this embodiment is used.
In this embodiment, a vehicle employs the automotive airbag described in this embodiment.
