A kind of automobile side airbag air bag and its folding method

Abstract

The invention discloses an air pocket of an automobile side airbag. The edges of an upper air pocket cloth and a lower air pocket cloth of the air pocket are sewn by sewing threads, an air inlet is arranged at one end of each air pocket cloth, a spacing air cloth pocket for dividing each air pocket cloth into two inflatable areas is arranged in the middle of each of the upper air pocket cloth and the lower air pocket cloth, and a vent hole is arranged on each spacing air cloth pocket. Airflow blown into each air pocket cloth from the corresponding air inlet is blown into one inflatable area and then blown into the other inflatable area through the vent hole, and the air pocket is folded in a certain mode and can be effectively and evenly unfolded when being inflated, so that safety of shoulders and heads of drivers and passengers is ensured. Besides, the unfolding effect of the air pocket is more effectively ensured by the folding mode of the air pocket, and the protection performance of the safety airbag is improved.

Description

technical field [0001] The invention relates to an automobile safety air bag, in particular to an air bag structure in a side air bag and a folding method for the air bag. Background technique [0002] Automobile airbags are important safety components in automobiles to protect the driving safety of drivers and passengers. When an accident occurs in a vehicle, it is extremely important that the airbags can be inflated and deployed in time and smoothly. There is an air bag in the side air bag of the car. The air bag is a fabric with a certain strength that is cut into a specific shape and sewn into a designed shape with tools. Under certain conditions, it can be inflated and deployed to protect the occupants and reduce injuries. Working principle: When the side airbag device works, the airbag sewn into a specific shape is inflated by the high-pressure gas generated by the gas generator, and unfolded into a certain shape to protect the occupants. [0003] The shape and struct...

Problems solved by technology

[0003] The shape and structure of the air bag has an important influence on the protection effect of the deployment. At present, the air bag structure generally adopts a bag-like structure formed by simply sewing together along the fabric cutting edge. The effect is not ideal, and the effective protection area on the side is difficult to meet the design requirements, thus affecting the effective protection of the occupants
