Abstract
Description
The present invention relates to an airbag apparatus, and more particularly to an airbag apparatus capable of adjusting the deployment pressure of the airbag cushion.
In general, the airbag device is a device that protects the passengers by the gas generated from the inflator flows into the airbag cushion in the event of an automobile accident, the airbag cushion is expanded and expanded by the gas.
Recently, after the passenger is loaded on the airbag cushion, the head and neck portions of the passenger are injured by excessive deployment pressure of the airbag cushion. In particular, in North America, laws on the merchandise of such airbag devices have been established and strictly evaluated whether the head and neck of the passenger are injured by the pressure of the airbag cushion.
Therefore, in the early stage of deployment of the airbag cushion, it prevents excessive discharge of gas to maintain the deployment pressure and promotes early deployment, and additionally discharges the gas at an appropriate time before and after the passenger is loaded onto the airbag cushion to injure the chest and chest of the passenger. There is a need for an airbag apparatus that can reduce injuries.
The problem to be solved by the present invention is to provide an airbag apparatus in which the opening size of the vent hole is gradually adjusted according to the expansion size of the airbag cushion so that the gas is gradually discharged through the vent hole without being discharged at once.
The problems of the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.
In order to achieve the above object, the airbag device according to an embodiment of the present invention, the airbag cushion is formed when the gas is inflated and the vented gas is discharged, the shielding the vent hole, once It is disposed along the circumference of the vent hole is coupled to the airbag cushion, the other end is a shielding member disposed in the center of the vent hole, and the shielding member to the other end of the shielding member to gradually open the vent hole One end is coupled to include a tether for pulling the other end of the shielding member.
The details of other embodiments are included in the detailed description and drawings.
In the airbag apparatus according to the present invention, since the size of the shielding member opening the vent hole is gradually adjusted according to the expansion size of the airbag cushion, the gas is gradually discharged through the vent hole without being discharged at once.
The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.
