Problems solved by technology

However, this side air curtain device has only one air chamber and the corresponding inflation port, so the inflation speed is relatively slow, which reduces the deployment speed of the side air curtain, which easily hinders the normal deployment of the side air curtain when the car's side wall trim is seriously deformed. The safety of car drivers cannot be effectively guaranteed

Embodiment Construction

[0026] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0027] Such as figure 1 As shown, the air curtain 1 on this side comprises an air bag body formed by sewing the edges of two pieces of air bag cloth up and down. Connected gas inlet 7.

[0028] Adjacent air chambers 2 are separated by sewing the middle of the upper and lower two airbag cloths with sewing thread 5, and the entire airbag cloth is divided into a plurality of air chambers 2, and the dividing lines formed by sewing thread 5 are straight lines and parallel to each other, so that After the air chamber 2 is inflated, the entire side air curtain 1 is deployed in the same direction.

[0029] Such as figure 2 , image 3 As shown, it is a car safety device with a side air curtain 1, including a gas generator 3, a...

Abstract

The invention provides a side gas curtain and an automobile safety device comprising the side gas curtain and belongs to the technical field of automobile safety. The side gas curtain solves the problem that the spreading speed of gas bags of an existing automobile side gas curtain is low. The automobile safety device comprising the side gas curtain comprises gas generators, an interior ceiling trim and the side gas curtain arranged in the interior ceiling trim. The interior ceiling trim is provided with a weakening line structure facilitating burst of the side gas curtain. The side gas curtain is provided with multiple independent gas chambers. Each gas chamber is provided with an inflation port communicated with the corresponding gas generator. The gas chambers are arranged in a line, and the inflation direction of the gas chambers is perpendicular to the arrangement direction of the gas chambers. Since the side gas curtain is provided with the multiple gas chambers, and each gas chamber is provided with one independent gas generator, the side gas curtain can be inflated simultaneously, and the spreading speed of the side gas curtain is substantially increased; meanwhile, the problem that the side gas curtain is prevented from spreading normally due to serious deformation of the side-body interior trim is avoided, and the effect that the side gas curtain protects the security of an automobile driver is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of automobile safety, and relates to a side air curtain and an automobile safety device with the side air curtain. Background technique [0002] In the process of a side collision of a car, the door, body side wall and sill structure are needed to absorb and transmit the side impact energy. At the same time, side airbags are also needed to assist in protecting the driver's life and reducing the damage. [0003] But at present, because the living space of the side occupants of a single-person car is very narrow, and the side wall of the vehicle body is also easy to deform when a side collision occurs, it is impossible to protect the occupants according to the traditional arrangement and inflation deployment of side airbags and side air curtains. [0004] For example, the utility model published by the Chinese Patent Application No. 201220535344.9 discloses a side air curtain air bag, which includes an air bag...
