Automotive safety airbag assembly

Abstract

The invention discloses an automotive safety airbag assembly. The automotive safety airbag assembly comprises a shell, a gas generator is arranged at the bottom end of the interior of the shell, a lower airbag body is arranged on the outer side of the top end of the gas generator, an upper airbag body is sewn on the top end of the lower airbag body, a pressing plate is arranged at the joint between the lower airbag body and the gas generator, and the top end, the left side and the right side of a gas dividing cover are provided with a top exhaust hole, a left exhaust hole and a right exhaust hole correspondingly. According to the automotive safety airbag assembly, the gas dividing cover, the pressing plate and a corrugated pressing plate cooperate, the upper airbag body and the lower airbag body are combined to form a whole airbag, and thus the sealing performance is strengthened while the fixing effect is improved; after entering the airbag, gas is exhausted through the top exhaust hole, the left exhaust hole and the right exhaust hole, so that the gas is uniformly ejected out in the left, upper and right directions; and accordingly, the sewing position between the upper airbag body and the lower airbag body can be effectively prevented from being torn, the protective effect of the airbag is improved, inflating is uniform, and the airbag can be completely inflated and expanded quickly and evenly.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile safety airbag assembly. Background technique [0002] During a frontal collision of a car, the driver's airbag can well protect the driver's head, neck and chest, and effectively reduce the driver's injury in the accident. Usually, the diameter of the airbag and the size of the vent hole , the length of the drawstring and other factors have a very important impact on the performance of the airbag, and also directly affect the protection effect of the airbag on the occupant. The airflow guide cover is arranged in the airbag bag, the airflow guide cover is a U-shaped flexible fabric, the airflow guide cover is distributed with the air outlet connected with the airbag bag, and the gas generator is arranged in the U-shaped cavity of the airflow guide cover In the middle of the airbag, the edge of the airflow guide cover is sewn with the inner wall of the airbag bag...

Problems solved by technology

[0002] During a frontal collision of a car, the driver's airbag can well protect the driver's head, neck and chest, and effectively reduce the driver's injuries in the accident. Usually, the diameter of the airbag and the size of the vent hole , the length of the drawstring and other factors have a very important impact on the performance of the airbag, and also directly affect the protection effect of the airbag on the occupant. The airflow guide cover is arranged in the airbag bag, the airflow guide cover is a U-shaped flexible fabric, the airflow guide cover is distributed with an air outlet connected with the airbag bag, and the gas generator is arranged in the U-shaped cavity of the airflow guide cover In the middle of the airbag, the edge of the airflow guide cover is sewn with the inner wall of the airbag bag, and the area where the airbag bag is connected to the two ends of the airflow guide cover is provided with a linear exhaust port. Although this patent can ensure that the pressure inside the airbag bag will not be too high and cause harm to the human body. Secondary damage, but when the airbag pops up, the upper part of the airbag will be overwhelmed by the instantaneous impact force of the gas, which will cause the upper part of the airbag to tear at the sewing thread, and the bottom will run out of air due to poor sealing, resulting in incomplete inflation of the airbag without rapid expansion
