When the airbag 24 is in the folded state, the second tether 26 is located within the airbag sheath 21, and the second tether 26 is in a relaxed state; when the airbag 24 is in an inflated condition, the second tether 26 is in tension and the upper portion of the second tether 24 is located outside the airbag sheath 21. The second lacing 26 can ensure that the whole airbag 24 has good tension support when the airbag 24 is in an inflated state, and the safety is improved.
The operation of the airbag package 2 of the present embodiment is specifically described below:
as shown in fig. 6, when the automobile is in normal driving, a child sits on the seat body 1, the air outlet 230 of the high-pressure air bottle 23 is in a closed state, the airbag 24 is in a folded state and is folded and contained in the airbag sheath 21, the whole volume is small, and the normal use of the safety belt assembly 10 is not affected;
as shown in fig. 7, when the vehicle collides, the air outlet 230 of the high-pressure air cylinder 23 is opened, and the high-pressure gas stored in the high-pressure air cylinder 23 enters the bag cavity 240 from the air outlet 230 of the high-pressure air cylinder 23, so that the airbag 24 starts to expand and burst through the top of the airbag cover 21, and forms an inverse "C" shape under the combined action of the first and second fastening belts 25 and 26, as shown in fig. 8, when the head of the child leans forward, the child touches the surface of the airbag 24, thereby playing a role of buffering, avoiding or reducing the injury to the head of the child, and further improving the safety.
The above embodiments are only for illustrating the technical idea and features of the present invention, and the purpose of the present invention is to enable those skilled in the art to understand the content of the present invention and implement the present invention, and not to limit the protection scope of the present invention by this means. All equivalent changes and modifications made according to the spirit of the present invention should be covered in the protection scope of the present invention.
