Abstract

An airbag apparatus for a panorama roof includes: an inflator generating gas; a gas guide connected to the inflator so as to receive the gas discharged from the inflator; a tether guide arranged along the longitudinal direction of the panorama roof; an airbag having one side connected to the gas guide so as to receive the gas discharged from the gas guide, arranged at the gas guide in a state where the airbag is folded, and connected to the tether guide so as to shield the panorama roof while being unfolded along the tether guide; a moving member connected to the other side of the airbag, and moved along the tether guide; and a driving unit connected to the moving member, and moving the moving member to fold or unfold the airbag.

Claims

1. An airbag apparatus for a panorama roof, comprising:

an inflator generating gas;

a gas guide connected to the inflator so as to receive the gas discharged from the inflator;

a tether guide arranged along the longitudinal direction of the panorama roof;

an airbag having one side connected to the gas guide so as to receive the gas discharged from the gas guide, arranged at the gas guide in a state where the airbag is folded, and connected to the tether guide so as to shield the panorama roof while being unfolded along the tether guide;

a moving member connected to the other side of the airbag, and moved along the tether guide; and

a driving unit connected to the moving member, and moving the moving member to fold or unfold the airbag.

2. The airbag apparatus of claim 1, wherein the driving unit comprises:

a wire connected to the moving member, and arranged in parallel to the tether guide;

a first winding part connected to one side of the wire, and winding the wire to move the moving member toward the gas guide; and

a second winding part connected to the other side of the wire, and winding the wire to move the moving member toward the opposite side of the gas guide.

3. The airbag apparatus of claim 2, wherein the wire is connected to either side of the moving member, and arranged in parallel to the tether guide.

4. The airbag apparatus of claim 3, wherein the wire is passed through the airbag at either side of the airbag in a state where the airbag is folded in a zigzag shape.

5. The airbag apparatus of claim 3, wherein two first winding parts are connected to the respective wires.

6. The airbag apparatus of claim 5, wherein when the first winding parts move the moving member toward the gas guide, the airbag is folded in a zigzag shape by the moving member.

7. The airbag apparatus of claim 3, wherein two second winding parts are connected to the respective wires.

8. The airbag apparatus of claim 3, wherein the first winding part winds the wire to fold the airbag, and

the second winding part winds the wire to shield the panorama roof as the airbag is unfolded.

9. The airbag apparatus of claim 1, wherein the tether guide is arranged at either side of the panorama roof so as to support either side of the airbag.

10. The airbag apparatus of claim 9, wherein a plurality of guide tabs are connected to either side of the airbag, and

the tether guide is inserted into the plurality of guide tabs.

11. The airbag apparatus of claim 1, wherein the moving member is arranged perpendicular to the tether guide.
