The invention provides a pneumatic bag body and an automobile seat. The pneumatic bag body comprises at least three sub air bag bodies which are arranged in a stacked mode in the first direction. At least one air port for exchanging with external air is formed in one sub air bag body positioned at the end part; a gas channel is communicated between every two adjacent sub gas bag bodies; the sub air bag body is provided with a first side and a second side which are distributed along the first direction; the gas channel communicated with the first side of the same sub gas bag body forms a first orthographic projection on the standard plane, and the gas channel communicated with the second side forms a second orthographic projection on the standard plane; the overlapping area of the first orthographic projection and the second orthographic projection is larger than zero and smaller than the area of the first orthographic projection and/or the area of the second orthographic projection; the first direction is perpendicular to the standard plane. A discontinuous through air path structure is adopted, the instant air explosion phenomenon of the middle air bag is avoided, and the problem that transient abnormal sound is generated in the air inflation process of the pneumatic bag body is solved.

    本申请提供一种气动囊体及汽车座椅,所述气动囊体包括至少三个沿第一方向层叠布置的子气袋体;位于端部的其中一个子气袋体上设置有至少一个用于与外部气体交换的气口;相邻的两个子气袋体之间连通有气体通道;子气袋体具有沿所述第一方向分布的第一侧和第二侧;与同一子气袋体的第一侧连通的气体通道在标准面上形成第一正投影,与第二侧连通的气体通道在标准面上形成第二正投影;第一正投影和第二正投影的重叠面积大于零,且小于第一正投影的面积和/或第二正投影的面积;第一方向垂直于标准面。本申请采用了不连续贯通的气路结构,避免了中间气袋的瞬间气爆现象的产生,解决了气动囊体充气过程中产生短暂异音的问题。
