BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a curtain airbag deployment device,

The present invention relates to an apparatus for testing a deployment force of a curtain airbag for a vehicle,

More specifically, at least one load cell is fixedly disposed on an outer side surface of a vehicle using a mount capable of adjusting and fixing the position, and the inflating force of the curtain airbag deployed inside the vehicle due to a vehicle collision is applied And the load is transmitted to the load cell along a connection rod disposed through the vehicle body portion, thereby testing the deployment force of the curtain airbag for a vehicle using the load cell.

BACKGROUND ART [0002] Generally, an air bag applied to a vehicle is a technique applied to secure the driver's safety in the event of a vehicle collision, including a sensor recognizing the collision and an air bag module expanding in the event of a collision. The airbag module is configured such that when a collision is detected by the sensor, the working gas device is exploded and the bag of the airbag module is instantaneously expanded (short time of about 50/1000 seconds) do.

On the other hand, in recent years, in order to further improve the stability of the vehicle, the application range of the airbag is gradually widening. In the past, a curtain airbag applied to the side portion was applied in order to protect the occupant from a side impact, and thus, a wider range of passenger protection was provided.

However, there has been a side effect that the airbag of the vehicle may cause injury to the occupant due to excessive deployment, or depending on the position of the occupant who is the object of protection of the airbag, in the event of rapid deployment.

This side effect is seen in the front airbags, but more particularly in curtain airbags deployed on the side of the occupant. That is, the curtain airbag is disposed closer to the occupant than the front airbag, and the curtain airbag deploying force must be adjusted more precisely to prevent a secondary injury that may be caused thereby.

Further, since the curtain airbag needs to cover the entire side surface of the occupant when a side collision occurs, the curtain airbag should be installed so as to cover a wider area than the front airbag. When the area covered by the airbag is widened, ≪ / RTI > or required).

Therefore, in order to solve the above problems, a precise test process is performed before the airbag is mounted on the vehicle.

As shown, the conventional airbag deployment test tested airbag deployment by testing collisions with dummies caused by deployment of the airbag during deployment of the airbag using a dummy and a high-speed camera. However, as described above, the method of testing the development using the dummy has a disadvantage in that a lot of testing costs are incurred because the dummy that generates a large cost is used and the dummy is maintained at every test.

As another conventional technique for testing the airbag deploying force, a method of testing the deploying force at the deployment of the airbag by virtue of computer simulation has been used, but this method has limitations in considering all factors that can be applied in actual situations And it was not possible to predict an unexpected situation occurring in a real situation, and it was a problem in terms of accuracy.
