Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a side safety air curtain device for automobiles, which mainly solves the problem that the traditional side air curtain collision protection area is limited and the structure is unstable. The side safety air curtain device has a simple and stable overall stitching structure, which increases the protection area of ​​the side collision, and no non-inflatable area affects the adjustment of the design protection range, and its stitching method is not affected by the different structural shapes of the vehicle, which improves the structural versatility

Abstract

A lateral safety air curtain device for an automobile and a manufacturing method thereof are disclosed. The lateral safety air curtain device for automobile comprises an air bag body and a connectingcloth sheet, wherein that interior of the air bag body is an inflatable cavity, air holes are arrange on the connecting cloth sheet, and the connecting cloth sheet is sewn together with the air bag body aft the connecting cloth sheet is closed annularly, so that the inflatable cavity forms a child-mother cavity structure which is communicated. The manufacturing method comprises the steps of obtaining a main cloth sheet I, a main cloth sheet II and a connecting cloth sheet by cutting the base cloth, annularly connecting a plurality of connecting cloth sheets and performing sleeving from the inside to the outside, which is sequentially sewn between the main cloth sheet I and the main cloth sheet II, The edge positioning stitching of the main cloth sheet I and the main cloth sheet II has theadvantages of simple and stable overall structure, high production efficiency, low manufacturing cost, enlarged side impact protection area, and the stitching mode is not affected by different vehiclestructural shapes, thereby improving the structural universality.

Description

technical field [0001] The invention relates to the technical field of safety devices for vehicles, in particular to an automobile side safety air curtain device and a manufacturing method thereof. Background technique [0002] Automobile airbags include front airbags and side airbags. The working principle of automobile airbags is that during the driving process of the car, the sensor system continuously sends speed change information to the control device, which is analyzed and judged by the control device. If the measured acceleration , speed change or other indicators exceed the predetermined value and a real collision occurs, the control device sends an ignition command to the gas generator or the sensor directly controls the ignition, and an explosion reaction occurs after ignition to generate gas or release the compressed gas in the gas storage tank Filled with crash air pockets. When the occupant is in contact with the air bag, the collision energy is absorbed throu...
