Problems solved by technology

Therefore, in the above-mentioned prior art, when the human body collides with the airbag, the gas will gather from the center to the periphery with the sewing thread and form a relatively large local gas pressure, which may cause the sewing thread to rupture.

Embodiment Construction

[0013] see figure 1 The schematic diagram of the three-dimensional mechanism of the airbag shown in the present invention provides a kind of automobile airbag, which is made of a single piece of fabric material 1, and the two ends of the fabric material 1 are relatively centered around, and the Both ends are sewn together to form a barrel-shaped body, the surrounding barrel wall of the barrel-shaped body is the side wall of the airbag, the first end surface 11 of the barrel-shaped body becomes the front of the airbag after being closed, the The second end face 12 of the barrel-shaped body is connected to a gas generator (not shown) for inflating the airbag.

[0014] The automobile safety airbag adopting the above-mentioned structure, because it is made of a single piece of fabric material, has the advantages of simple structure and easy control and guarantee of process quality compared with the existing double-piece stitched structure. At the same time, it has overlapping sid...

Abstract

The invention relates to an automobile safe air bag. The automobile safe air bag is made of single piece of fabric material; the two end parts of the fabric material surround relative to the center; the two end parts are sewed along the axial direction to form a barrel-shaped body; the surrounding barrel wall of the barrel-shaped body is the side wall of the air bag; the first tail end face of the barrel-shaped body is closed to form the front side of the air bag; and the second tail end face of the barrel-shaped body is connected with a gas generator for inflating the air bag. The automobile safe air bag can bear the collision impact from a passenger and maintain integrity and particularly avoids breakage at the periphery of the air bag. The novel air bag structure can be made of a light textile material so as to reduce weight and cost. The automobile safe air bag has the characteristics of simple structure and convenience for manufacture and assembly, so that the automobile safe air bag can be utilized in a large range.

Description

technical field [0001] The present invention relates to automotive airbags, and more particularly to airbag structures that provide frontal protection for occupants. Background technique [0002] Car airbags are widely used in modern cars to provide personal protection. Its working process is: when the car is in a collision or similar danger, the sensor on the body senses the motion change information and sends the excitation information to the connected gas generating device, which inflates the airbag to provide soft protection for the occupants. Generally, airbags can be divided into frontal airbags and side airbags according to the directions in which the airbags are constrained and protected, such as frontal airbags installed in the steering wheel and in the dashboard of a car to provide frontal restraint protection for the face and chest, and installed in Side airbags on the seats or doors to provide chest, hip and head side restraint protection. [0003] Determined b...
