Embodiment Construction

[0018] figure 1 It is a schematic diagram of the airbag on the driver's side. For the passenger's side airbag and other airbags, such as side airbags, the implementation of the present invention is the same. The following is the driver's side airbag and an adaptive row Stomata are described as an example.

[0019] Such as figure 1 As shown, the present invention has a bag body 1 and a gas generator 2 installed in the bag body 1 , and the bag body 1 is provided with an exhaust hole 3 . The air vent 3 is a round hole or other hole shapes of a certain size cut out on the bag body 1, figure 1 Described as a circular vent hole. A reinforced circular cloth piece 4 (or other hole shape consistent with the shape of the vent hole) is sewn at the position corresponding to the vent hole 3 inside the bag body 1, figure 1 Shown by the dotted line in the center, a central hole 401 is provided in the middle of the reinforcing circular cloth sheet 4, and the hole shape of the center hole ...

Abstract

A self-adaptive gas vent structure of an automobile safety airbag comprises a bag body and a gas generator mounted in the bag body, and a gas vent is formed in the gas body. The self-adaptive gas vent structure of the automobile safety airbag is characterized in that a reinforcing circular cloth piece is sewn at the position, corresponding to the gas vent, inside the bag body, a center hole is formed in the middle of the reinforcing circular cloth piece, the hole shape of the center hole and the hole shape of the gas vent are the same, and the gas body is folded along the connecting line of the center of the gas generator and the center of the gas vent in the bag body and then forms two layers of bag bodies which are then sewn together. The defects that the gas vent of a traditional automobile safety airbag is fixed and unchanged, and part of gas is discharged out from a traditional gas vent in the air inflation process are overcome. The gas vent is in the closed state during air inflation, when the bag body of the airbag is fully inflated or the bag body is subjected to pressure, the gas vent can be opened automatically, gas loss is reduced, the gas generated by the generator is fully utilized, the impact kinetic energy of a driver and passengers can be buffered, and therefore the protection performance to the driver and the passengers is improved.

Description

Technical field [0001] The invention relates to an adaptive vent structure for automobile airbags, which can be used on various types of airbags, such as driver airbags, passenger airbags, side airbags, etc. Background technique [0002] At present, generally when a car collides, after the airbag installed on the car is deployed, the gas generator inflates high-pressure gas into the airbag body. At the same time, in order to improve the energy-absorbing and buffering effect of the airbag, the airbag body is designed with a discharge pores. [0003] The vent hole on the known air bag body is fixed. When the generator inflates the bag body, part of the gas is discharged from the vent hole at the same time, which reduces the protective effect of the air bag. Contents of the invention [0004] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art and improve an automobile airbag adaptive vent structure, which can improve the i...
