Is disposed inside the airbag cushion, comprising a tether portion for separating the airbag cushion into the upper and lower, the tether portion is coupled to the left and right sides of the airbag cushion, spaced apart from the front surface of the airbag cushion to form a nozzle portion The present invention relates to a vehicle airbag apparatus having improved airbag cushion deployment.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle airbag apparatus, and more particularly, to a vehicle airbag apparatus having improved deployability of an airbag cushion.
In general, an airbag device of a vehicle is installed in front of a driver's seat or front passenger's seat and is installed for the purpose of protecting the life and the body of a driver and a passenger while the airbag cushion is momentarily inflated during a collision of the vehicle.
Vehicle airbags are divided into driver airbags mounted on the steering wheel to protect the driver of the driver's seat and passenger airbags mounted on the instrument panel in the front of the passenger's seat to protect passengers of the passenger seat. The driver's airbag is a mandatory feature and the passenger seat airbag is an option. However, in order to protect passengers, vehicles that use a passenger seat airbag as an essential specification are increasing.
The deployment structure of the passenger seat airbag device is a structure in which the airbag cushion is in full bloom and the passenger's head, neck and chest are sequentially contacted before the passenger's head and chest contact each other. In addition, the passenger seat airbag device is generally a structure of one chamber to adjust the internal pressure through the vent hole of the airbag cushion when the passenger contacts. In addition, in order to secure the stability of the shape of the deployment, the upper and lower tethers are placed in front of the restraint distance to the passengers. In other words, the tether is an auxiliary means for maintaining the shape of the airbag cushion in full bloom.
This passenger airbag device is the most important deployment stability and pressure control. Therefore, there must be a structure for fixing the top and bottom and left and right, otherwise the up and down and left and right flow occurs before the airbag cushion is in full bloom. Therefore, it was difficult to control the pressure regulation, there was a big problem of risk of head and neck injury.
The problem to be solved by the present invention is to provide a vehicle airbag device for protecting the passenger by improving the deployability of the airbag cushion.
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, an airbag device for a vehicle according to an embodiment of the present invention, the airbag cushion which is deployed forward toward the passenger when the gas is introduced; Is disposed inside the airbag cushion, comprising a tether portion for separating the airbag cushion into the upper and lower, the tether portion is coupled to the left and right sides of the airbag cushion, spaced apart from the front surface of the airbag cushion to form a nozzle portion do.
The details of other embodiments are included in the detailed description and drawings.
According to the vehicular airbag apparatus of the present invention, there are one or more of the following effects.
First, there is an advantage to improve the deployment of the airbag cushion.
Second, there is an advantage of simplifying the assembly by simplifying the work process.
Third, there is an advantage in that the weight and cost are reduced due to the removal of spare parts.
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.
