Description
BACKGROUND OF THE
2. Description of the Related Art Generally, an airbag module mounted on a vehicle protects an occupant while the airbag tube is deployed toward a room when a large impact force such as a collision and a collision shock is generated, Side airbag module, and curtain airbag module.
This airbag is subjected to several crash tests to determine whether it is operating normally in the event of a collision, including the SmallOverlap crash test, which performs an operator safety test of an accident that occurs during a 25% .
Here, as the behavior of the dummy in the event of a small overlap collision of the vehicle progresses in the oblique direction to the left rather than the front, the head portion of the dummy collides with the edge of the cushion and the head of the dummy slides on the cushion, There is a problem that an injury due to a secondary impact such as a collision occurs.
A problem to be solved by the present invention is to provide an airbag for preventing a head of a driver from moving outside the edge of a cushion or a cushion protecting area in a small overlap frontal collision, thereby improving secondary collision.
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 according to an embodiment of the present invention includes a steering wheel provided on a vehicle and a cushion provided inside the steering wheel, wherein both sides of the cushion are arranged in the centrifugal direction of the cushion And a rear panel disposed between the front panel and the steering wheel to be coupled to the front panel.
The front panel may further include a tether having one end connected to the inside of the front panel and another end connected to the inside of the rear panel to constrain the front panel when the cushion is deployed.
Further, the folding portion may be sewn by being welded and torn when the cushion is deployed.
Also, the front panel may be circularly sewn with a tether.
Further, a vent hole may be formed in the rear panel to discharge gas when the cushion is deployed.
The tether may be formed with one end connected to the rear panel and the other end connected to the center of the front panel.
The details of other embodiments are included in the detailed description and drawings.
According to the airbag of the present invention, there is one or more of the following effects.
The head of the driver is seated in the airbag protection area in the event of a collision, thereby preventing injuries caused by the second collision.
It also has the effect of meeting the small overlap rule without increasing the volume of the additional device and curtain airbag.
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.
