The invention provides a vehicle rear collision passenger protection safety air bag. The vehicle rear collision passenger protection safety air bag comprises an air generator, an air bag assembly, a generator support and an air bag fixing piece. The air bag module is fixed to the rear portion of the vehicle body, an air bag assembly in a folded state is contained in the air bag module, an air guide isolation belt structure is arranged in the air bag assembly and limits the flow direction of air entering an air bag, and the air generator is communicated with the air bag of the air bag module. The gas generator is fixed to a vehicle body rear metal plate through the generator support, a gap is formed between the middle of the generator support and the vehicle body rear metal plate, an elastic protruding structure is arranged on the inner side of the middle of the generator support to abut against the vehicle body metal plate, and the gas generator is installed on the outer side of the middle of the generator support. Vibration can be absorbed through deformation of the elastic protrusions in the vehicle running process, noise generated by collision between the generator support and a vehicle body is avoided, after collision occurs, a large amount of gas generated by the gas generator flows into the gas bag, the gas bag blocks the rear portion of the vehicle body after being inflated and expanded, and injuries caused by collision between passengers and the rear portion of the vehicle body are avoided.

    本发明提供一种车辆后碰乘员保护安全气囊,其中包括气体发生器、气袋总成、发生器支架、气囊固定片。气囊模块固定于车体后部,气囊模块内容纳有折叠状态的气袋总成,气袋总成内部设有导气隔离带结构,限定进入气袋的气体流向,气体发生器与气囊模块的气袋相通;气体发生器通过发生器支架固定于车体后部钣金,发生器支架的中部与车体后部钣金之间具有间隙,发生器支架中部内侧设有弹性凸起结构抵接车体钣金,气体发生器安装于发生器支架中部外侧。在车辆行驶过程中可通过弹性凸起变形吸收振动,从而避免发生器支架与车体碰撞产生噪音,且在发生碰撞后,气体发生器产生大量气体流入气袋,气袋充气膨胀后挡在车体后部,避免乘员与车体后部碰撞造成伤害。
