Abstract

A mounting structure of a curtain airbag in a vehicle is disclosed. The structure is adapted to easily form an inflation passage between a pillar trim and pillar by using a head liner; therefore, the overall portions of the curtain airbag can smoothly expand during the deployment. Such mounting structure may be performed with the head liner, pillar trim, and force transmission means.

Claims

1. A structure for storing a curtain airbag for a vehicle, comprising:

a head liner that forms a space with a roof side rail for storing the curtain airbag;

a pillar trim located adjacent to said head liner and forming a space with a pillar for storing said curtain airbag; and

force transmission means that is in close proximity to said head liner and pillar trim and extends from an interior of said head liner to an interior of said pillar trim for transmitting a force of said head liner, which tends to move down into a passenger compartment when said curtain airbag inflates, to said pillar trim, wherein said force transmission means comprises;

an extension plate that contacts at one end thereof with an inner surface of said head liner while the other end extends to an interior of said pillar trim; and

a fastener that couples said pillar trim to said extension plate; and

a supporter integrally formed with said extension plate for maintaining an end of said fastener at a distance from said pillar and for locating said pillar trim apart from said pillar.

2. The structure as defined in claim 1, wherein said fastener further comprises:

a boss protruding inward at said pillar trim;

a coupling screw penetrating from said boss to said extension plate;

wherein said supporter maintains an end of said coupling screw at a distance from said pillar; and

a cover concealing said boss.
