Abstract

Disclosed herein is a passenger airbag chute that includes a chute frame, a door plate disposed in an opening of the chute frame, a hinge allowing the door plate to be rotatably connected to the chute frame, and a screen including a frame coupling part coupled to the chute frame, a door coupling part coupled to the door plate, and a hinge coupling part formed between the frame coupling part and the door coupling part and coupled to the hinge.

First claim

What is claimed is:

1. A passenger airbag chute comprising:
a chute frame;
a door plate disposed in an opening defined on the chute frame;
a hinge allowing the door plate to be rotatably connected to the chute frame; and
a screen comprising a frame coupling part coupled to the chute frame, a door coupling part coupled to the door plate, and a hinge coupling part formed between the frame coupling part and the door coupling part and coupled to the hinge,
wherein the door plate comprises connectors formed at a position spaced apart from the hinge and connected to the chute frame, the connectors being configured to be broken by deployment pressure of an airbag.

2. The passenger airbag chute according to claim 1 , wherein:
the chute frame comprises a frame fusion rib protruding toward and joined to a crash pad; and
the door plate comprises a door fusion rib protruding toward and connected to the crash pad.

3. The passenger airbag chute according to claim 1 , wherein the hinge has flexibility to be flexibly bent by deployment pressure of an airbag.

4. The passenger airbag chute according to claim 1 , wherein the hinge is formed integrally with the chute frame and the door plate by injection molding, and is thinner than the chute frame and the door plate.

5. The passenger airbag chute according to claim 1 , wherein the screen is made of a fabric material, and is formed integrally with the chute frame, the door plate, and the hinge by insert injection molding.

6. A passenger airbag chute, comprising:
a chute frame;
a door plate disposed in an opening defined on the chute frame;
a hinge allowing the door plate to be rotatably connected to the chute frame; and
a screen comprising a frame coupling part coupled to the chute frame, a door coupling part coupled to the door plate, and a hinge coupling part formed between the frame coupling part and the door coupling part and coupled to the hinge,
wherein the screen is configured such that at least one of the frame coupling part, the door coupling part, and the hinge coupling part is exposed out of the chute frame, the door plate, and the hinge.

7. The passenger airbag chute according to claim 1 , wherein the frame coupling part comprises:
a frame reinforcing portion positioned inside the chute frame; and
a first exposed portion formed continuously with the frame reinforcing portion and exposed out of the chute frame.

8. The passenger airbag chute according to claim 1 , wherein the door coupling part comprises:
a door reinforcing portion positioned inside the door plate; and
a second exposed portion formed continuously with the door reinforcing portion and exposed out of the door plate.

9. The passenger airbag chute according to claim 1 , wherein the hinge coupling part comprises:
one or more composite hinge portions coupled to the hinge to reinforce rigidity of the hinge; and
one or more screen hinge portions formed continuously with the one or more composite hinge portions and disposed in parallel with the hinge to rotatably support the door plate.

10. The passenger airbag chute according to claim 1 , wherein the hinge coupling part comprises:
one or more composite hinge portions coupled to the hinge to reinforce rigidity of the hinge; and
one or more hollow hinge portions formed to be hollow between the frame coupling part and the door coupling part.

11. A passenger airbag chute, comprising:
a chute frame;
a door plate disposed in an opening defined on the chute frame;
a hinge allowing the door plate to be rotatably connected to the chute frame; and
a screen comprising a frame coupling part coupled to the chute frame, a door coupling part coupled to the door plate, and a hinge coupling part formed between the frame coupling part and the door coupling part and coupled to the hinge,
wherein:
one end of the screen is positioned on a bottom of the chute frame;
an intermediate portion of the screen is positioned on an upper surface of the hinge; and
an other end of the screen is positioned on a bottom of the door plate.

12. A passenger airbag chute, comprising:
a chute frame;
a door plate disposed in an opening defined on the chute frame;
a hinge allowing the door plate to be rotatably connected to the chute frame; and
a screen comprising a frame coupling part coupled to the chute frame, a door coupling part coupled to the door plate, and a hinge coupling part formed between the frame coupling part and the door coupling part and coupled to the hinge,
wherein the frame coupling part comprises:
a frame reinforcing portion positioned inside the chute frame; and
a first exposed portion formed continuously with the frame reinforcing portion and exposed out of the chute frame.

13. A passenger airbag chute, comprising:
a chute frame;
a door plate disposed in an opening defined on the chute frame;
a hinge allowing the door plate to be rotatably connected to the chute frame; and
a screen comprising a frame coupling part coupled to the chute frame, a door coupling part coupled to the door plate, and a hinge coupling part formed between the frame coupling part and the door coupling part and coupled to the hinge,
wherein the door coupling part comprises:
a door reinforcing portion positioned inside the door plate; and
a second exposed portion formed continuously with the door reinforcing portion and exposed out of the door plate.

14. A passenger airbag chute, comprising:
a chute frame;
a door plate disposed in an opening defined on the chute frame;
a hinge allowing the door plate to be rotatably connected to the chute frame; and
a screen comprising a frame coupling part coupled to the chute frame, a door coupling part coupled to the door plate, and a hinge coupling part formed between the frame coupling part and the door coupling part and coupled to the hinge,
wherein the hinge coupling part comprises:
one or more composite hinge portions coupled to the hinge to reinforce rigidity of the hinge; and
one or more screen hinge portions formed continuously with the one or more composite hinge portions and disposed in parallel with the hinge to rotatably support the door plate.

15. A passenger airbag chute, comprising:
a chute frame;
a door plate disposed in an opening defined on the chute frame;
a hinge allowing the door plate to be rotatably connected to the chute frame; and
a screen comprising a frame coupling part coupled to the chute frame, a door coupling part coupled to the door plate, and a hinge coupling part formed between the frame coupling part and the door coupling part and coupled to the hinge,
wherein the hinge coupling part comprises:
one or more composite hinge portions coupled to the hinge to reinforce rigidity of the hinge; and
one or more hollow hinge portions formed to be hollow between the frame coupling part and the door coupling part.
