Embodiment Construction

[0014] refer to figure 1 , the automotive airbag of the present invention is mainly composed of a main airbag 1, an auxiliary airbag 2 and a two-stage gas generator 3, and the two-stage gas generator 3 works under the control of an external controller. The two-stage gas generator 3 is composed of two independent integral gas generators connected end to end, which have two gas outlets, and can produce different gas release amounts under the control of the controller. The auxiliary airbag 2 is sewn on the outer surface of the main airbag 1, and the surface of the main airbag 1 corresponding to the auxiliary airbag 2 is provided with an air hole 4, and the airtight air delivery channel 5 is sewn into the air hole. One of the gas outlets of the two-stage gas generator 3 communicates with the main airbag 1 , and the other gas outlet is closely connected to the air delivery channel 5 .

[0015] During general implementation, the volume ratio of the auxiliary airbag 2 and the main a...

Abstract

The invention discloses an airbag for an automobile. The airbag for the automobile comprises a main airbag and a two-stage gas generator arranged in the main airbag. An axillary airbag is sewn on the outer surface of the main airbag, an air hole is formed in the position, corresponding to the axillary airbag, at the surface of the main airbag, the air hole is sewn with an airtight air duct, one air outlet of the two-stage gas generator is communicated with the main airbag, and the other air outlet of the two-stage gas generator is tightly docked with the air duct. The airbag for the automobile is provided with the main airbag and the axillary airbag which can be inflated independently, the axillary airbag is provided with the special air duct and can be quickly inflated, when a relatively severe collision happens, the axillary airbag can be inflated within a short time and immediately fulfills the buffering function, then the main airbag can be expanded, and thus a more all-sided protection effect can be achieved. Therefore the airbag for the automobile can achieve the more all-sided protection effect and can meet security protection requirements under all kinds of circumstances.

Description

technical field [0001] The invention relates to a safety airbag for automobiles. Background technique [0002] The airbag system is a passive safety protection system, which is used in conjunction with seat belts to provide effective anti-collision protection for the occupants. [0003] When a collision accident occurs while the car is running, various sensors respond, and the electronic controller then acts to control the start of the gas generator. After receiving the signal, the gas generator ignites the gas generant to generate a large amount of gas, so that the airbag bag can be deployed rapidly in a very short time, and an elastic air cushion is formed on the front, side or top of the driver or passenger to absorb the impact energy. Thereby effectively protecting the head and chest of the human body from injury or reducing the degree of injury. [0004] In order to achieve a good protective effect, the current airbags are configured with a large capacity, but with th...
