Abstract

An assembling apparatus of a curtain airbag in a vehicle includes an inflator and an airbag cushion. The airbag cushion includes a body part configured to be unfolded if necessary to protect a passenger, an inlet configured to transmit air from the inflator into the body part, and a first extending part having a predetermined length and extending from the inlet towards the inflator side of the inlet. Also included are at least one bracket on which the inflator is supported and at least one fixed member configured to fix the inflator, enclosing an outside of the inflator.

Claims

1. An assembling apparatus of a curtain airbag in a vehicle, the apparatus comprising:

an inflator;

an airbag cushion including a body part configured to be unfolded if necessary to protect a passenger, an inlet configured to transmit air from the inflator into the body part, the inlet having a body part side and an opposing inflator side, and a first extending part having a predetermined length extending from the inlet towards the inflator side;

at least one bracket on which the inflator is supported; and

at least one fixed member configured to fix the inflator, enclosing an outside of the inflator,

wherein the at least one bracket includes a first bracket in front of the inflator and a second bracket in back of the inflator, and a first through hole is formed by a gap between the first bracket and the second bracket.

2. The assembling apparatus of claim 1, wherein the first extending part of the airbag cushion penetrates the first through hole.

3. The assembling apparatus of claim 2, wherein the first extending part penetrates the first through hole via a gap between the inflator and the bracket and is bent towards the body part to be fixed to the inflator by the fixed member.

4. The assembling apparatus of claim 2, wherein the first extending part penetrates the first through hole via a gap between the inflator and the bracket, an end of the first extending part is bent by a predetermined length, and the bent portion is sewn to form a thickness increasing part having a predetermined thickness.

5. The assembling apparatus of claim 2, wherein the first extending part extends over the whole outer peripheral surface of the inlet.

6. The assembling apparatus of claim 1, wherein the airbag cushion further includes a second extending part, the first and second extending parts are disposed on opposing sides of the inflator, and the first through hole and a second through hole corresponding to the first and second extending parts are each disposed on opposing sides of the bracket, wherein the first extending part penetrates through the first through hole and is bent towards the body part, the second extending part penetrates through the second through hole and is bent towards the body part, and the first and second extending parts are simultaneously fixed by the fixed member.

7. The assembling apparatus of claim 1, wherein the bracket includes a coupling part coupling the bracket to a body of the vehicle, the first extending part is disposed under the inflator, the first through hole is disposed under the bracket, and the first extending part penetrates the first through hole via a gap between the inflator and the bracket and is fixed by being wound around the coupling part of the bracket.

8. The assembling apparatus of claim 1, wherein the bracket includes a coupling part coupling the bracket to a body of the vehicle, and the first extending part is disposed under the inflator and is fixed by being wound around the coupling part of the bracket.

9. The assembling apparatus of claim 1, wherein the at least one fixed member includes two or more fixed members spaced apart from each other.

10. The assembling apparatus of claim 9, wherein the two or more fixed members are three fixed members.
