Problems solved by technology

[0003] Although the equipment of airbags has indeed reduced the number of deaths in collision accidents, it is not completely safe. The more common injuries caused by airbags are due to the fact that the airbags are inflated at a high speed, so they have not yet completed their "explosion". During the process, if the human body is hit by the airbag, it will cause various injuries of varying degrees of severity

Embodiment Construction

[0014] As shown in Figure 1, the automobile airbag inflator provided by the present invention comprises a shell-like casing 10, a gas generating device 2 assembled inside the casing 10, an airbag bag seat 40 located on one side of the casing 10, It further includes an elastic valve 50 disposed on the other side of the housing 10 relative to the airbag seat 30 . Wherein, the casing 10 is a hollow body, wherein two opposite sides are set as through-shaped, and are respectively defined as the suction end 101 and the gas outlet end 102. The two opposite sides are provided with fixed seat plates 11 extending outward, and the other two opposite sides are respectively provided with perforations 12 for the gas generating device 2 to penetrate and assemble.

[0015] Please also if figure 2 As shown, the gas generating device 2 includes an extension tube 20 assembled between two perforations 12, a gas generator 30 assembled at one end of the extension tube 20, and a gas generator 30 lo...

Abstract

The inflator for safety air bag in car includes one thin casing, one gas generator inside the casing, one air bag set on one side of the casing, and one elastic plate valve in the other side of the casing. The gas generator includes one extending pipe inside the casing, one baffle between the extending pipe and the elastic plate valve and one gas generating unit to one end of the extending pipe, and has one gas flow passage between the baffle and the extending pipe. In case of collision accident of automobile, the chemical substances inside the gas generating unit produce chemical reaction to release great amount of nitrogen and the nitrogen flows to the outlet while sucking air from outside so as to inflate the safety air bag with the mixed gas.

Description

technical field [0001] The invention relates to a vehicle accessory, in particular to an automobile safety air bag. Background technique [0002] When the car is running at high speed, when the car body is hit, the driver and passengers in the front seat will rush forward due to inertia and hit the car body (including the steering wheel, instrument panel, etc.) In addition to seat belts, more and more cars include airbags as basic equipment. The airbags are installed on the steering wheel and the instrument in front of the passengers, so that when the car body is hit, the airbag can be inflated to reduce the impact of the human body on the car body Opportunity. The current airbag inflation method is to fill the airbag with chemical substances. When the car is moving, the electronic sensor receives information such as changes in vehicle speed, vehicle vibration status, and braking mode at any time. , Immediately generate a current pulse, ignite the chemical substances in th...
