The present invention relates to a head lining structure of a vehicle equipped with a curtain air bag, and more particularly, to a head lining structure of a vehicle equipped with a curtain air bag that can prevent the curtain air bag from being abnormally deployed into the center pillar trim when the curtain air bag is operated. It is about.

Recently, vehicles equipped with airbags to protect drivers and passengers in the event of a crash have become commonplace, and curtain airbags in vehicles to protect passengers from accidents that may occur from the side of the vehicle, as well as from collisions that occur in front of the vehicle. This is being applied.

1 is a cross-sectional configuration of a head lining of a vehicle equipped with a conventional curtain airbag.

Conventional curtain airbag device is provided with a curtain airbag 20 inside the head lining 10, the curtain airbag 20, the first bracket 30 for guiding the deployment direction of the curtain airbag 20, and the curtain A second bracket 40 is provided to prevent the airbag from flowing into the loop side when the airbag 20 is deployed.

The third bracket 50 supports the top of the center pillar trim 60 and prevents the curtain airbag 20 from flowing into the trim 30.

Such a conventional head lining structure serves to prevent the curtain airbag 20 from being deployed inside the center pillar trim 60 of the first bracket 30, but it is difficult to maintain the curtain airbag so that the curtain airbag is the center pillar trim ( 60) There is an abnormal development inward.

In order to solve this problem, conventionally, the flange portion 61 is formed on the top of the center pillar trim 60, and the third bracket 50 is provided to contact the flange portion 61 so that the curtain airbag is centered when deployed. Prevents the filler trim 60 from flowing into the inside.

However, such a conventional head lining structure is complex and difficult to assemble because it is composed of a plurality of components. In addition, there is a problem that the head lining is pushed out while deteriorating the appearance beauty.

Specifically, since the curtain airbag should be mounted while pushing up the center pillar trim 60 while the head lining 10 sags downward, the assembly of the center pillar trim is difficult.

In addition, since the bent end 11 of the headlining 10 is assembled against the flange 61 of the center pillar trim, the headlining is deformed by the stress and pushed out, thereby degrading the appearance.

The present invention is to solve the above drawbacks, the vehicle is equipped with a curtain airbag that can reduce the number of components by improving the structure while preventing the curtain airbag unexpanded inside the center pillar trim during operation of the curtain airbag To provide a head lining structure of the.

The headlining structure of the vehicle of the present invention includes a first fixing part fixed to a center pillar inner panel in a headlining structure for fixing a curtain airbag provided along the inside of the headlining of the vehicle interior, and the first fixing part. A second fixing portion which is bent in the upper portion and fixed to the top of the center pillar trim, a bent portion extending from the second fixing portion to bend from the inside of the vehicle body to the outside of the vehicle body; It is achieved by integrally forming the guide bracket curved inward from the side.

2 and 3 is a view showing the head lining structure of the vehicle of the present invention, Figure 2 is a cross-sectional view of the head lining of a vehicle equipped with a curtain airbag according to the present invention, Figure 3 is a vehicle head of the present invention In the lining structure, it is a cross-sectional block diagram showing a state where the curtain airbag is operated.

An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 2, the head lining structure of the vehicle of the present invention includes a center pillar inner panel 101 and a center pillar trim 102 in a head lining structure for fixing a curtain air bag provided along the inside of the head lining of a vehicle interior. The guide bracket 100 is fixed to the top and provided to surround the curtain airbag 103.

The guide bracket 100 has a first fixing part 110 fixed to the center pillar inner panel 101 and a second height fixed by the first fixing part 110 to be bent and extended from the upper end of the center pillar trim 102. And a bent portion 130 extending from the second fixing portion 120 to bend from the inside of the vehicle body to the outside of the vehicle body, and extending from the bent portion 130 to surround the curtain airbag 103. It is curved inward from the outside of the vehicle body so as to be integrally formed.

The first fixing part 110 and the second fixing part 120 are firmly fixed to the center pillar inner panel 101 and the center pillar trim 102 with bolts, respectively.

Preferably, the horizontal distance between the bent portion 130 of the guide bracket 100 and the upper end of the center pillar trim 102 may be minimized so that the air bag may flow into the center pillar trim 102 when the curtain air bag is deployed. Minimize the space.

On the other hand, the end of the headlining 104 is preferably protruded and fixed to the center pillar trim upper end 102a to absorb the assembly tolerance even if the headlining 104 sags downward.

As shown in Figure 3, the headlining structure of the present invention configured as described above, when the curtain airbag 103 is deployed, the headlining 104 is removed from the center pillar trim upper end 102a by the inflating force of the airbag to the inside of the vehicle interior. Deformed to, the curtain airbag 103 is normally deployed along the bent portion 130 of the guide bracket 100 toward the vehicle side.

On the other hand, since the lower end of the guide bracket 100 is firmly fixed to the inner panel 101 and the trim 102 by the first fixing part 110 and the second fixing part 120, respectively, the air bag is deployed. The guide bracket is deformed by the inflating force generated at the front to prevent the air bag from being abnormally deployed into the center pillar trim.

The headlining structure of the vehicle equipped with the curtain airbag of the present invention as described above has one guide bracket that can be rigidly supported to guide the deployment direction of the curtain airbag, so that when the curtain airbag is deployed, the inside of the center pillar trim is released. Abnormal development can be prevented, and the invention is also effective to minimize the number of components to improve the assembly.
