The invention relates to a far-end air bag device which comprises an air bag, the air bag is provided with a first cavity, a second cavity and an air bag communicating part arranged between the first cavity and the second cavity, and the air bag communicating part can enable the first cavity and the second cavity to be in fluid communication. And the air bag conduction part is configured to generate a bent air passage when the air bag is inflated and unfolded, so that the second cavity is at least partially overlapped with the first cavity in the projection along the transverse direction of the air bag when the air bag is inflated and unfolded. Therefore, through the bent air passage formed by the air bag conduction part, the function of a double-cavity structure can be realized, and a thicker inflatable air bag can be realized in the overlapped area of the first cavity and the second cavity, so that more air bag protection can be provided for the head of a driver and passengers, and meanwhile, the smoothness of air flow from the first cavity to the second cavity is ensured.

    本公开涉及一种远端气囊装置,所述远端气囊装置包括气袋,所述气袋具有:第一腔体、第二腔体和设置在第一腔体和第二腔体之间的气袋导通部,所述气袋导通部能够将第一腔体和第二腔体流体连通,其特征在于,所述气袋导通部构造成在气袋充气展开时产生折弯气道,从而在气袋充气展开时第二腔体在沿气袋横向方向的投影中与第一腔体至少部分重叠。在此,通过由气袋导通部形成的折弯气道,可实现双腔结构功能并且在第一腔体和第二腔体的重叠区域内可实现更厚的充气气袋厚度,以便为驾乘人员头部提供更多的气囊保护,同时保证从第一腔体至第二腔体的气流通畅。
