Abstract

Provided are a curtain airbag apparatus and a method of manufacturing the same, which may prevent a head of an occupant from being moved forward after coming into contact with an airbag. To this end, according to the curtain airbag apparatus according to the exemplary embodiment of the present invention, a deployment guide is disposed to penetrate a deployment ring coupled to one surface of the airbag, and tightened by expansive force of the airbag to allow the airbag to be bent in a shape that protrudes toward the other surface.

Claims

1. A curtain airbag apparatus comprising:

an inflatable airbag;

a deployment ring which is coupled to one surface of the airbag; and

a deployment guide which penetrates the deployment ring and is tightened by expansive force of the airbag to allow the airbag to be bent in a shape that protrudes toward the other surface.

2. The curtain airbag apparatus of claim 1, wherein both ends of the deployment guide are coupled to the airbag.

3. The curtain airbag apparatus of claim 1, wherein a through hole which the deployment guide penetrates is formed in the deployment ring.

4. The curtain airbag apparatus of claim 3, wherein the deployment guide is installed to be movable through the through hole.

5. The curtain airbag apparatus of claim 1, wherein when the airbag is deployed, one surface of the airbag is directed toward the outside of the vehicle, and the other surface of the airbag is directed toward the interior of the vehicle.

6. The curtain airbag apparatus of claim 1, wherein an upper end of the deployment guide is coupled to an upper end of the one surface of the airbag, and a lower end of the deployment guide is coupled to a lower end of the one surface of the airbag.

7. The curtain airbag apparatus of claim 6, wherein the deployment ring is coupled to the lower end of the one surface of the airbag above the lower end of the deployment guide.

8. The curtain airbag apparatus of claim 1, wherein a lower end of the deployment guide is disposed to be closer to a front portion or a rear portion of the airbag than an upper end.

9. The curtain airbag apparatus of claim 1, wherein a length of the deployment guide is longer than a length of the airbag in an up and down direction, and at least one end of the deployment guide is disposed to be spaced apart from the deployment ring in a front and rear direction so that the deployment guide is tightened while the airbag is deployed.

10. The curtain airbag apparatus of claim 1, wherein the deployment guide is provided as a plurality, so that includes a first deployment guide and a second deployment guide.

11. The curtain airbag apparatus of claim 10, wherein an upper end of the first deployment guide and an upper end of the second deployment guide are disposed to be spaced apart from each other in a front and rear direction, and a lower end of the first deployment guide and a lower end of the second deployment guide are disposed to be spaced apart from each other in the front and rear direction.

12. The curtain airbag apparatus of claim 10, wherein both ends of the first deployment guide are disposed to be spaced forward apart from the deployment ring, and both ends of the second deployment guide are disposed to be spaced rearward apart from the deployment ring.

13. A method of manufacturing a curtain airbag apparatus, the method comprising:

a first step of spreading raw fabric of a deployment ring out on an airbag, and coupling a central portion of the raw fabric to the airbag;

a second step of coupling both ends of the raw fabric, and completely forming the deployment ring;

a third step of spreading a first deployment guide out on the airbag, and coupling a lower end of the first deployment guide to the airbag;

a fourth step of spreading a second deployment guide out on the airbag, and coupling a lower end of the second deployment guide to the airbag;

a fifth step of allowing an upper end of the first deployment guide to pass through the deployment ring from the lower side to the upper side, and pulling out the upper end of the first deployment guide;

a sixth step of allowing an upper end of the second deployment guide to pass through the deployment ring from the lower side to the upper side, and pulling out the upper end of the second deployment guide;

a seventh step of folding a lower end of the airbag upward so that the deployment ring is disposed between folded portions of the airbag;

an eighth step of coupling the upper end of the first deployment guide to the airbag; and

a ninth step of coupling the upper end of the second deployment guide to the airbag.

14. The method of claim 13, wherein in the seventh step, the airbag is folded upward based on a point one-third of the length of the airbag in an up and down direction from the lower end of the airbag.
