vehicle airbag

Abstract

The invention discloses a vehicle airbag, which is characterized in that it comprises: an airbag cushion, which is formed with an exhaust hole for discharging inflowing gas to the outside; an exhaust guide member, which is arranged inside the airbag cushion, and is formed in a The exhaust hole guides the gas that has flowed into the interior of the airbag cushion; and an exhaust cover provided between the exhaust guide member and the airbag cushion at the initial stage of deployment of the airbag cushion The guide hole and the vent hole are opened at the end of deployment, and at least one of the guide hole and the vent hole is closed at the middle stage of deployment of the airbag cushion. According to the present invention, even if children aged 3 to 6 or elderly and infirm passengers are seated, it is possible to reduce the neck and / or head injuries of passengers in this out-of-position (Out Of Position) state. , can reduce the weight of components, reduce the weight of the airbag, and save costs.

Description

technical field [0001] The invention relates to a vehicle airbag, in particular to a vehicle airbag capable of synthesizing and realizing multiple exhaust functions. Background technique [0002] Now, most vehicles generally have a driver's seat airbag, a passenger's seat airbag, etc., which are deployed toward the passenger when a vehicle collision occurs, reducing the damage to the upper body and face of the driver and passengers. [0003] In order to reduce the damage to the neck and / or head of passengers, even for children aged 3 to 6 or elderly and infirm passengers, the airbag for the passenger seat is in this out-of-position (OutOfPosition: OOP) The state must also be expanded. [0004] In such a case, when the airbag cushion is deployed, the high-pressure gas expands the airbag cushion momentarily, so the airbag cushion inflates, and when the occupant's head contacts the inflated airbag cushion, the injury from the airbag cushion puts the occupant in more dangerous...

AI Technical Summary

Problems solved by technology

[0007] However, the above-mentioned airbag cushion needs to have the active venting part and the low-risk venting part, so the airbag cushion has a complex structure, a large number of parts, is difficult to manufacture, and increases the manufacturing cost.

[0008] In addition, it is necessary to add components for opening and closing the active exhaust part to the TRU, so the cost increases.
