Abstract

The present invention relates to an A-pillar mounting structure of a curtain airbag. In particular, an A-pillar mounting structure in which an upper mounting member of a boss of an A-pillar trim is separated from the during deployment of an airbag and the trim separated from the A-pillar is prevented from going far away by a cap that is prevented from being scattered by a cap scattering preventing means connected to a mounting member or a trim connecting means. The present invention relates to an A-pillar mounting structure in which a curtain airbag is installed and to which an A-pillar trim is coupled. The A-pillar trim includes an A-pillar trim boss for connecting the A-pillar trim to an A-pillar, and an upper mounting member provided to an upper end of the A-pillar trim boss and formed to be separable from the A-pillar trim boss during deployment of the curtain airbag.

Claims

1. An A-pillar mounting structure in which a curtain airbag is installed and to which an A-pillar trim is coupled, wherein the A-pillar mounting structure comprises:

an A-pillar trim boss for connecting the A-pillar trim to an A-pillar;

an upper mounting member provided to an upper end of the A-pillar trim boss and formed to be separable from the A-pillar trim boss during deployment of the curtain airbag; and

a cap,

wherein a coupling means is fixed to the A-pillar through the upper mounting member so that the A-pillar trim is detachably coupled to the A-pillar,

wherein the upper mounting member is integrally formed with the A-pillar trim boss which is thinner than the A-pillar trim boss, and the upper mounting member comprises a plurality of slots which are radially formed from a coupling hole formed at a center of the upper mounting member, and

wherein the cap has a receiving portion that is formed at a lower end of the A-pillar trim boss of the A-pillar trim, and the cap is connected to the A-pillar mounting structure through a cap scattering preventing means.

2. The A-pillar mounting structure of claim 1, wherein the upper mounting member is integrally formed with the A-pillar trim boss by a plurality of supporting ribs.

3. The A-pillar mounting structure of claim 1, wherein the upper mounting member has an overlapping member and is inserted into an upper end of the A-pillar trim boss from an inner side thereof.
