Abstract

This invention relates to a pillar ramp structure which prevents interfering with the deployment of a curtain airbag. In one embodiment, the present invention includes a pillar ramp housing which is fixed to an inner panel, and a folding bracket in which the first end of the folding bracket is installed to a front surface of the pillar ramp housing and the second end of the folding bracket extends toward a pillar trim.

Claims

1. A pillar ramp structure for preventing interference with deployment of a curtain airbag, comprising:

a pillar ramp housing connected to an inner panel and having a cover which is opened upon activation of the curtain airbag so that the curtain airbag expand therethrough, wherein the curtain airbag is received in the pillar ramp housing; and

a folding bracket in which a first end of the folding bracket is installed to the cover of the pillar ramp housing and a second end of the folding bracket extends toward a pillar trim;

wherein the pillar ramp housing is bent in a plurality of locations to form a perforated rectangular structure.

2. A pillar ramp structure for preventing interference with deployment of a curtain airbag, comprising:

a pillar ramp housing connected to an inner panel and having a cover which is opened upon activation of the curtain airbag so that the curtain airbag expand therethrough, wherein the curtain airbag is received in the pillar ramp housing; and

a folding bracket in which a first end of the folding bracket is installed to the cover of the pillar ramp housing and a second end of the folding bracket extends toward a pillar trim;

wherein the cover is a plate member having a hook member connected to the first end of the folding bracket and wherein the pillar housing includes a connecting member that is provided below the plate member and is formed such that the folding bracket can be installed thereto.

3. The pillar ramp structure of claim 2, wherein a slot groove is formed on an upper surface of the pillar ramp housing such that a fixing member for being coupled to the inner panel can be connected to the slot groove.

4. The pillar ramp structure of claim 3, wherein the pillar ramp housing, the folding bracket, and the fixing member are integrally formed.

5. The pillar ramp structure of claim 4, wherein the folding bracket is made of a hard material.

8. The pillar ramp structure of claim 2, wherein the folding bracket has a rotating axis which is connected to the connecting member of the pillar ramp housing.

6. A pillar ramp structure for preventing interference with deployment of a curtain airbag, comprising:

a pillar ramp housing connected to an inner panel and having a cover which is opened upon activation of the curtain airbag so that the curtain airbag expand therethrough, wherein the curtain airbag is received in the pillar ramp housing; and

a folding bracket in which a first end of the folding bracket is installed to the cover of the pillar ramp housing and a second end of the folding bracket extends toward a pillar trim;

wherein the folding bracket is shaped such that the folding bracket closely adheres to the cover of the pillar ramp housing.

7. A pillar ramp structure for preventing interference with deployment of a curtain airbag, comprising:

a pillar ramp housing connected to an inner panel and having a cover which is opened upon activation of the curtain airbag so that the curtain airbag expand therethrough, wherein the curtain airbag is received in the pillar ramp housing; and

a folding bracket in which a first end of the folding bracket is installed to the cover of the pillar ramp housing and a second end of the folding bracket extends toward a pillar trim;

wherein the folding bracket has a rotating axis which is connected to a connecting member arranged on the pillar ramp housing is connected to a connection member and the connection member is connected to the folding bracket.

9. A pillar ramp structure for preventing interference with deployment of a curtain airbag, comprising:

a pillar ramp housing connected to an inner panel and having a cover which is opened upon activation of the curtain airbag so that the curtain airbag expand therethrough, wherein the curtain airbag is received in the pillar ramp housing; and

a folding bracket in which a first end of the folding bracket is installed to the cover of the pillar ramp housing and a second end of the folding bracket extends toward a pillar trim;

wherein a plurality of projections protrude from both sides of the front surface of the first end of the folding bracket.

10. The pillar ramp structure of claim 9, wherein a plurality of insertion grooves are formed on both sides of the front surface of the second end of the folding bracket at positions corresponding to the positions of the plurality of projections.

11. A pillar ramp structure for preventing interference with deployment of a curtain airbag, comprising:

a pillar ramp housing connected to an inner panel and having a cover which is opened upon activation of the curtain airbag so that the curtain airbag expand therethrough, wherein the curtain airbag is received in the pillar ramp housing; and

a folding bracket in which a first end of the folding bracket is installed to the cover of the pillar ramp housing and a second end of the folding bracket extends toward a pillar trim;

wherein a mounting hole that is coupled with the pillar trim is formed on the first end of the folding bracket.

12. A pillar ramp structure for preventing interference with deployment of a curtain airbag, comprising:

a pillar ramp housing connected to an inner panel and having a cover which is opened upon activation of the curtain airbag so that the curtain airbag expand therethrough; and

a folding bracket in which a first end of the folding bracket is installed to the cover of the pillar ramp housing and a second end of the folding bracket extends toward a pillar trim coupled to a head lining and is coupled thereto, wherein the pillar trim is configured to be disengaged from the head lining upon the activation of the curtain airbag;

wherein the first and second ends of the folding bracket are co-axially pivotal with a rotation axis.

13. The pillar ramp structure of claim 12, wherein the rotation axis of the first and second ends of the folding bracket are disposed on end portion of the cover.
