Abstract

A curtain airbag module may include an inflator provided above an upper end portion of a B-pillar, a mounting bracket for mounting the inflator, an airbag disposed along a roof side rail under the inflator and connected at a central portion thereof to the inflator, a guide ramp disposed around an upper end portion of a B-pillar trim and holding the airbag therein, thus allowing the airbag to be deployed without being interfered with by the B-pillar trim, and a mounting flap connecting the mounting bracket and the guide ramp.

Claims
