The invention provides a cushion airbag for preventing passengers from excessively diving, which comprises a main body assembly, and the main body assembly comprises an airbag main body, a preformed hole, a gas generator and a clamping ring; a reserved hole is formed in one side of the front portion of the upper surface of the air bag body, an air generator is fixedly connected to the inner side wall of the reserved hole, and two clamping rings are fixedly connected to the outer side wall of the air generator. The air bag main body is arranged between the seat pelvis and the seat foam, when an automobile is collided, a collision detection system of the automobile detects a collision signal and triggers the gas generator to work, so that gas enters the inflation cavity of the air bag main body from the deflation hole in the rear part of the gas generator; the air bag main body at the front section of the thigh of a passenger sitting on the seat is expanded and inflated, so that the front section area of the seat cushion is quickly lifted, the risk that the passenger dives is reduced, the collision energy of the upper trunk is relieved, the injury caused by the lumbar vertebra pressure of the passenger is reduced, and the restraint effect of the safety belt on the passenger is improved.

    本发明提供了一种防止乘员过度下潜的坐垫气囊,包括主体组件,所述主体组件包括气袋主体、预留孔、气体发生器和卡环;所述气袋主体的上表面前部一侧开设有预留孔,所述预留孔的内侧壁固定连接有气体发生器,所述气体发生器的外侧壁固定连接有两个卡环。本发明通过将气袋主体设置于座椅骨盆和座椅发泡之间,当汽车发生碰撞时,汽车的碰撞检测系统检测到碰撞信号并触发气体发生器工作,从而气体从气体发生器后部的泄气孔进入气袋主体的充气腔,对乘坐于座椅上的乘客大腿前段的气袋主体膨胀充气,进而快速抬起座椅坐垫前段区域,降低乘员下潜的风险,缓解上躯干的碰撞能量,降低乘员腰椎压力而导致的伤害,提升了安全带对乘员的约束效果。
