It is provided to fully inform the person having the scope of the invention, which is defined only by the scope of the claims. Like reference numerals refer to like elements throughout.

Hereinafter, the present invention will be described with reference to the drawings for describing a curtain airbag device according to embodiments of the present invention.

1 is a perspective view of a curtain airbag device according to an embodiment of the present invention, Figure 2 is a cross-sectional view of the curtain airbag device according to an embodiment of the present invention, Figure 3 is a curtain airbag device according to an embodiment of the present invention Is a perspective view of an anti-rotation clip.

1 to 3, a curtain airbag apparatus according to an embodiment of the present invention is disposed on an inner panel of a vehicle and includes an airbag cover 20 accommodating a cushion 21 therein; Anti-rotation including a bent portion 11 supporting the lower side of the airbag cover 20 and guiding the deployment direction of the cushion 21 when the cushion 21 is deployed, and a fastening portion 12 coupled to the inner panel at the upper side thereof. A clip 10; And one end is connected to the cushion 21, the other end includes a cushion mounting tab 30 is connected to the fastening portion 12, the bent portion 11 is formed on the lower side of the anti-rotation clip 10, the cushion It is formed to be bent inside the vehicle to guide the deployment direction of the (21) to the inside of the vehicle.

The airbag cover 20 is disposed on the upper inner panel of the vehicle along the longitudinal direction of the front and rear of the vehicle. In addition, the airbag cover 20 accommodates the curtain airbag cushion 21 therein, and the cushion 21 is inflated to protect the passenger's head when the vehicle crashes.

The airbag cover 20 has a hole through which the cushion mounting tab 30 passes. Therefore, the cushion mounting tab 30 may be connected to the cushion 21 accommodated in the air bag cover 20.

The anti rotation clip 10 is disposed between the airbag cover 20 and the inner panel of the vehicle.

The anti-rotation clip 10 includes a bent portion 11 formed at the lower side and a fastening portion 12 formed at the upper side. In addition, the bent portion 11 and the fastening portion 12 is formed integrally consisting of one panel.

The bent part 11 supports the lower part of the airbag cover 20 and is formed of a material that is elastically deformable to absorb the shock applied to the lower part of the vehicle when the cushion 21 is deployed due to the collision of the vehicle. Therefore, the impact on the filler trim disposed in the downward direction of the airbag cover 20 is reduced to prevent breakage of the filler trim.

The bent portion 11 is formed by convexly bending inward of the vehicle to guide the deployment direction of the cushion 21 toward the inside of the vehicle when the cushion 21 is deployed due to a vehicle collision.

In another embodiment of the present invention, the bent portion 11 may be formed in a "c", "C" shape, etc. in the inward direction of the vehicle.

The fastening part 12 is formed with a fastening hole 15 into which the bolt 40 for coupling the cushion mounting tab 30 and the upper inner panel of the vehicle is inserted.

Therefore, the bolt 40 is inserted through the fastening hole 15, and the bolt 40 is coupled to the nut to be in close contact with the cushion mounting tab 30 and the inner panel.

The fastening part 12 is formed with a protrusion 13 at a portion engaged with the cushion mounting tab 30, and the protrusion 13 is cushioned by the pressure applied to the cushion mounting tab 30 when the cushion 21 is deployed. The mounting tab 30 is not rotated. Therefore, the protrusion 13 is preferably formed in close contact with the cushion mounting tab 30.

2, the other end of the cushion mounting tab 30 connected to the fastening part 12 is disposed between the fastening part 12 and the inner panel of the vehicle, and the protrusion 13 is in the direction of the inner panel of the vehicle. Protrudes. In addition, a hole corresponding to the protrusion 13 is formed in the inner panel of the vehicle, and the protrusion 13 is preferably fitted into the hole of the inner panel.

The anti-rotation clip 10 has a through hole 14 through which the cushion mounting tab 30 passes between the fastening portion 12 and the bent portion 11. The through hole 14 is preferably formed above the airbag cover 20 above the fastening hole 15 rather than above. therefore The cushion mounting tab 30 penetrates through the through hole 14 to prevent the cushion mounting tab 30 from being rotated by the pressure applied to the cushion mounting tab 30 when the cushion 21 is deployed.

One end of the cushion mounting tab 30 is connected to the cushion 21 and the other end of the cushion mounting tab 30 is coupled to the fastening part 12 of the anti-rotation clip 10.

The cushion mounting tab 30 is formed by bending the middle portion, and preferably, one end and the other end connected to the fastening portion 12 and the cushion 21 are formed in a plane parallel to the longitudinal direction, and the middle portion is perpendicular to the longitudinal direction. It is preferably formed in a plane. In addition, a hole into which the bolt 40 is inserted is formed at the other end connected to the fastening part 12.

Referring to the operation of the curtain airbag according to an embodiment of the present invention configured as described above are as follows

First, high-temperature, high-pressure gas is ejected from an inflator (not shown) during a vehicle crash.

The ejected gas flows into the cushion, and the cushion 21 rapidly expands.

When the cushion 21 is inflated, an impact is applied to the bent portion 11 formed below the anti-rotation clip 10 disposed between the vehicle inner panel and the airbag cover 20 that accommodates the cushion 21 therein. The bent portion 11 absorbs the impact to prevent breakage of the filler trim.

In addition, the bent portion 11 is bent convexly to the inside of the vehicle to guide the cushion 21 to be deployed inside the vehicle.

Although the above has been illustrated and described with respect to preferred embodiments of the present invention, the present invention is not limited to the specific embodiments described above, but in the art to which the invention pertains without departing from the spirit of the invention as claimed in the claims.
