Abstract

A roof-side structure includes a roof center rail which is engaged with the bottom surface of a roof panel and one end of which extends to a position of a curtain airbag, a roof rail gusset engaged between a roof side outer reinforcing panel and the one end of the roof center rail, and a side inner panel which is engaged with the roof rail gusset in a state that a curtain airbag is engaged with a front side of the one end of the roof center rail. Accordingly, since the roof rail gusset is arranged inside of the side inner panel so that it does not interfere with the curtain airbag, a layout of the curtain airbag is advantageous. Also, since it is not required to bend the roof rail gusset to connect the roof center rail and the side inner panel, in the event a broadside collision is applied to a vehicle, the roof rail gusset remains unbroken, and thus the rigidity of the roof center rail can be sufficiently reinforced.

Claims

1. A roof-side structure of a vehicle, comprising:

a roof center rail, one end of which extends to a portion of a curtain airbag and the other end of which is engaged with a bottom surface of a roof panel;

a roof rail gusset engaged between a roof side outer reinforcing panel and the one end of the roof center rail; and

a side inner panel, one end of which is coupled to the roof rail gusset, wherein the curtain airbag is coupled to a rear side of the one end of the side inner panel.

2. The roof-side structure as claimed in claim 1, wherein the roof rail gusset, the one end of the roof center rail, the one end of the side inner panel, and the curtain airbag are commonly coupled by a fastening member in series.

3. The roof-side structure as claimed in claim 2, wherein the fastening member is bolt and nut.

4. The roof-side structure as claimed in claim 1, wherein the roof rail gusset comprises:

a gusset body coupled to the one end of the roof center rail; and

first and second flanges bent from both distal ends of the gusset body toward the roof side outer reinforcing panel respectively and engaged with the roof side outer reinforcing panel.

5. The roof-side structure as claimed in claim 4, wherein the gusset body of the roof rail gusset, the one end of the roof center rail, the one end of the side inner panel, and the curtain airbag are commonly coupled by a fastening member in series.

6. The roof-side structure as claimed in claim 5, wherein the fastening member is bolt and nut.

7. The roof-side structure as claimed in claim 4, wherein the first and second flanges are inclined downwards with respect to a horizontal axis with a predetermined angle respectively.

8. The roof-side structure as claimed in claim 4, further comprising a third flange integrally extending from end of the second flange downwards with a predetermined angle therebetween.

9. A passenger vehicle comprising the roof-side structure as claimed in claim 1.
