Embodiment Construction

[0022] Such as figure 2 As shown, the airbag double-chamber structure airbag related to the present invention includes an airbag body 1 with a double-chamber structure. The air bag body 1 is composed of an air bag support cavity 101 and an air bag protection cavity 102 .

[0023] Such as image 3 , Figure 7 As shown, the air bag support cavity 101 is stitched from the bag sheet 101a. Firstly, the bag piece 101a is folded in half at the fold line L, and then the periphery of the bag piece 101a is sewn along the sewing line M to form the air bag supporting cavity. The airbag support cavity 101 is provided with two air conduction weakening lines 101b on the bag sheet 101a, forming two air conduction weakening regions 101A. The air bag support cavity 101 is also provided with a generator installation hole 101c on the bag sheet 101a.

[0024] Such as Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the airbag protection cavity 102 is formed by sewing a surroundi...

Abstract

An air bag with double cavity structure for automobile safety airbag, comprising an air bag body with double cavity structure, the air bag body is composed of an air bag support cavity and an air bag protection cavity; the air bag support cavity is connected with the air bag protection cavity Adjacent parts are provided with two air guide weakened areas, and the air bag protection cavity is provided with two air guide holes corresponding to the air guide weakened areas, and the air bag support cavity is connected with the air bag around the two air guide weakened areas. The two air guide holes of the protection chamber are connected around, so that the air bag support chamber and the air bag protection chamber are connected to form a complete air bag; the surface of the air bag support chamber is provided with a gas generator installation hole for installing the gas generator and fixing the air bag; The protective cavity of the air bag is provided with vent holes for controlling the internal pressure of the air bag. The present invention can realize the functional requirements of the sequential deployment of the air bag, thereby realizing the effective protection of the occupant's head, neck and chest; it is beneficial to generate suction to the occupant's head and neck when the air bag protection chamber contacts the occupant's head. It can reduce the occupant's head and neck injury.

Description

technical field [0001] The invention relates to an airbag structure of an automobile safety airbag, in particular to an automobile safety airbag double-cavity structure airbag installed at the front beam of the passenger side of the automobile ceiling. Background technique [0002] With the development of the automobile industry, more and more car front dashboards use larger display screens. In order to meet the protection requirements of front-seat occupants in car frontal collisions, more and more airbags for car frontal collision protection use roof panels. Installation scheme. [0003] At present, the airbags of the car roof airbags include curtain-shaped airbags, L-shaped airbags and chair-shaped airbags. The airbag structures are all single-chamber structures, and the airbags have no support. It cannot be accurately deployed between the occupant and the car dashboard, and the protection is not perfect. During the R&D process of roof airbags, it is necessary to develo...
