An airbag for automobiles with adjustable inflation strength

Abstract

The invention discloses an inflation intensity adjustable type safety gas bag for an automobile. The inflation intensity adjustable type safety gas bag comprises an automobile steering wheel and an inflating gas generation device shell. A roller electromechanical switch type gravity sensor is arranged on the left side of the inflating gas generation device shell. An ignition control circuit board is arranged on the right side of the roller electromechanical switch type gravity sensor. A coil silicon steel sheet type igniter is arranged in the ignition control circuit board. A gas generation agent is arranged outside a filter. A drying device is arranged above the gas generation agent. By the adoption of the inflation intensity adjustable type safety gas bag for the automobile, a drying effect on the gas generation agent with which the inflating gas generation device shell is filled can be achieved, the problem that the gas generation agent is located in the automobile for a long time and consequently damped and deteriorated is solved, it is guaranteed that the safety gas bag pops up smoothly in an emergency, and use is safe and convenient; and the problem that a user is harmed due to fact that the pressure of the safety gas bag is too large is solved.

Description

technical field [0001] The invention belongs to the technical field of safety airbags, and in particular relates to an automobile safety airbag with adjustable inflation force. Background technique [0002] The airbag is a device that inflates the airbag to protect the occupant before the occupant has a secondary collision during a collision. The airbag is used as a supplementary device to the occupant restraint of the seat belt and is called an airbag system. The airbag system is composed of an integrated airbag module composed of an airbag and an inflating mechanism (gas generator), a collision sensor system that senses a collision and issues a deployment command to the airbag module, and a wiring harness that transmits signals from the sensor. When a car collides, the airbag system is very effective in protecting the safety of the driver and passengers. At present, the airbag system is generally a steering wheel single airbag system or a double airbag system. When a ve...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an airbag for automobiles with adjustable inflating force, so as to solve the problem that the gas generating agent filled in the casing of the inflatable generating device proposed in the above-mentioned background technology is easy to get wet and deteriorate, which affects the smooth ejection of the airbag and the failure of the airbag in an emergency. The inflation strength of the airbag cannot be adjusted according to the deceleration of the car, and the air pressure of the airbag is likely to cause great harm to the user
