Curtain airbag device for vehicle

The invention relates to a curtain airbag device for a vehicle. When a curtain airbag (16) inflates and expands, an independent portion (54) inside a slit portion (52) inflates and expands toward a vehicle lower side toward a gap between a seat back (58A) and a center pillar garnish (50). If the independent portion (54) interferes with the seat back (58A), the independent portion (54) inflects inthe vehicle width direction. Meanwhile, regions of the curtain airbag (16) other than the independent portion (54) inflate and expand toward the vehicle lower side without being affected by the position of the independent portion (54). 本发明涉及用于车辆的帘式气囊装置。当帘式气囊(16)膨胀且展开时，狭缝部(52)内侧的独立部(54)朝向座椅靠背(58A)与中柱装饰物(50)之间的间隙向车辆下侧膨胀且展开。如果独立部(54)与座椅靠背(58A)干涉，则独立部(54)在车辆宽度方向上弯曲。同时，帘式气囊(16)的除独立部(54)之外的区域向车辆下侧膨胀且展开，而不受独立部(54)的位置的影响。
