The provision of the first tether 25 ensures that the airbag 24 is inverted "C" shaped in the inflated state, preventing the other end portion of the airbag 24 from tilting upward after inflation.
One end of the second tie 26 is fixedly connected to the middle of the airbag 24, and the other end of the second tie 26 is fixedly connected to the high-pressure gas cylinder accommodating body 22, in this embodiment: one end of the second tie 26 is fixedly connected to the airbag 24 on the outer wall of the air flow passage 2403, and a connection point of the other end of the second tie 26 with the high-pressure gas cylinder accommodating body 22 is located on the inner wall of the high-pressure gas cylinder accommodating body 22. The second lace 26 is provided with at least one, in this embodiment: as shown in fig. 4, two second tethers 26 are provided, one end portions of the two second tethers 26 are fixedly connected to the middle portion of the airbag 24, the other end portions of the two second tethers are fixedly connected to the high-pressure gas cylinder accommodating body 22, and the two second tethers 26 are in a cross shape, so that the airbag 24 is more uniformly stressed in an inflated state, and the left-right shaking amount in a collision is reduced. When the airbag 24 is in the folded condition, the second tether 26 is positioned within the airbag housing 21 and the second tether 26 is in the relaxed condition; when the airbag 24 is in the inflated condition, the second tether 26 is in tension and the upper portion of the second tether 24 is located outside the airbag housing 21. By providing the second tether 26, the airbag 24 as a whole can be ensured to have good tension support when the airbag 24 is in an inflated state, and safety is improved.
The following describes the operation of the airbag package 2 of the present embodiment in detail:
as shown in fig. 6, when the vehicle is running normally, the child sits on the seat body 1, and the air outlet 230 of the high-pressure air cylinder 23 is in a closed state, the air bag 24 is in a folded state and is folded and accommodated in the air bag cover 21, so that the overall volume is small, and the normal use of the safety belt assembly 10 is not affected;
As shown in fig. 7, when the automobile collides, the air outlet 230 of the high-pressure air bottle 23 is opened, and the high-pressure air stored in the high-pressure air bottle 23 enters the bag cavity 240 from the air outlet 230 of the high-pressure air bottle 23, so that the air bag 24 begins to expand and burst the top of the air bag wrapper 21, and forms a reverse C shape under the combined action of the first lacing 25 and the second lacing 26, as shown in fig. 8, if the head of the child leans forward, the head of the child touches the surface of the air bag 24, thereby playing a buffering role, avoiding or relieving the damage to the head of the child, and further improving the safety.
The above embodiments are provided to illustrate the technical concept and features of the present invention and are intended to enable those skilled in the art to understand the content of the present invention and implement the same, and are not intended to limit the scope of the present invention. All equivalent changes or modifications made in accordance with the spirit of the present invention should be construed to be included in the scope of the present invention.
