Inflatable device for automobile safety air curtain

Abstract

An inflatable device for an automobile safety air curtain, which has an inflatable part axially connected with a gas generating device and an air guide part in gas communication with the inflatable part, the inflatable device is a barrel-shaped body surrounded by a fabric material, the The inflatable part is the radially upper end and axially extending part of the fabric material barrel-shaped body, and the air guide part is the radially lower end and axially extending part of the fabric material barrel-shaped body, located in the inflatable part An air channel is formed between the fabric material barrel-shaped body part and the air guide part to connect the two with gas. The device of the present invention has simple structure and convenient processing. At the same time, the inflatable part and the air-guiding part are smoothly connected through their own structure, avoiding the use of sewing thread to fix the process and the possibility of subsequent potential damage; the air-guiding part is made of flexible fabric It is also convenient to adjust the area of ​​the air outlet, and then adjust the air output to form multi-dimensional regulation of the airbag to meet various inflation requirements.

Description

technical field [0001] The invention relates to an inflatable and air-guiding structure, in particular to an inflatable and air-guiding structure for an inflatable safety air curtain capable of protecting the head of a passenger when a side collision occurs. Background technique [0002] Side air curtains for automobiles provide protection for occupants in the event of a side collision, especially for the protection of the head. The air curtain in the prior art is arranged above the door along the longitudinal direction of the door. At the same time, in order to inflate the soft airbag in time and provide protection for it to expand from top to bottom, the gas generating device for inflating the airbag body needs to be located at a relatively high level. The height of the internal fixed arrangement, such as arranged in the middle or rear of the door. [0003] Since the air curtain has a long longitudinal length, the gas outlet of the gas generating device cannot inflate the...

AI Technical Summary

Problems solved by technology

[0004] However, the structure in the prior art is relatively complicated, requiring more sewing processes, and at the same time, some sewing threads will be subjected to gas impact destructive force because they are in the path of gas release.

In addition, due to the increase of the sewing surface, the gas release will not be smooth enough
