Problems solved by technology

[0003] At present, none of the airbag gas generators has an outer casing. The gas generator generates high-temperature gas above 300°C during operation, which directly burns the fabric and breaks through the airbag. Therefore, it is necessary to sew several layers of silicone-coated cloth on the part where the gas generator is installed. This increases the cost of the airbag and affects its foldability

Embodiment 1

[0029] refer to Figure 1 ~ Figure 4 As shown, an outer shell assembly of an airbag gas generator includes:

[0030] Outer casing body 1, it is hollow tubular and one end is provided with inlet 11, and described safety air bag gas generator is arranged in described outer casing body 1 through described inlet 11; Wrapped up, when the generator is working, the heat generated by the outer shell body 1 will no longer directly contact the airbag itself, thereby protecting the airbag, and simplifying the structure of the airbag, eliminating the need to sew several layers of silicone-coated cloth as a generator. The device installation part, thereby reducing the cost of the airbag and making the airbag easier to fold;

[0031] It is connected to the barrier nozzle 2 at the other end of the casing body 1, and the barrier nozzle 2 is provided with an air injection port 21 connected with the air bag. The barrier nozzle 2 buffers the airflow generated by the generator, preventing the a...

Embodiment 2

[0038] refer to figure 1 and Figure 5 As shown, the difference between this embodiment and the first embodiment is that the connection mode between the barrier nozzle 2 and the casing body 1 is different, and the casing body 1 and the barrier nozzle 2 are integrated.

Abstract

The present invention relates to the field of airbag components, and provides an outer shell assembly of an airbag gas generator, comprising: an outer shell body, which is hollow and tubular and has an inlet at one end, and the airbag gas generator passes through the The insertion port is arranged in the outer shell body; the barrier nozzle connected to the other end of the outer shell body, the barrier nozzle is a hollow cone with a circular arc transition at the top, and the side wall of the hollow cone is set There is an air jet connected to the air bag. An assembly hole for assembling the safety airbag gas generator is arranged on the outer shell body. The invention is used to block the heat generated by the airbag gas generator during operation, so that the gas generator can be directly installed, and it is no longer necessary to sew several layers of coated cloth for the gas generator installation part of the airbag, so that the airbag is easier to fold , Prevent the airbag itself from being burned out by the gas generator, and reduce the cost of the airbag.

Description

technical field [0001] The present invention relates to the field of safety airbag components, more specifically, relates to an outer shell assembly of a safety airbag gas generator. Background technique [0002] Airbags are mainly composed of airbag sensors, anti-collision airbags and electronic control devices. Airbag components are mainly composed of airbags, gas generators and igniters. [0003] At present, none of the airbag gas generators has an outer casing. The gas generator generates high-temperature gas above 300°C during operation, which directly burns the fabric and breaks through the airbag. Therefore, it is necessary to sew several layers of silicone-coated cloth on the part where the gas generator is installed. This increases the cost of the airbag and affects its foldability. Contents of the invention [0004] The invention provides an outer casing assembly of a gas generator for an airbag, which can effectively solve the above problems. [0005] The pre...
