The invention discloses an air bag installed in a vehicle door. The air bag mainly comprises a safety air bag controller, a whole vehicle data communication bus, the vehicle door, an air bag assemblyand the like. The safety air bag controller and the air bag assembly are connected with the whole vehicle data communication bus respectively. The air bag assembly is installed in a cavity between a vehicle door inner plate sheet metal part and a vehicle door outer plate sheet metal part. The air bag assembly comprises a collision sensor, a gas generator and an air bag body, the collision sensor is connected with the whole vehicle data communication bus, the gas generator is fixed in a cavity between a vehicle door inner plate and a vehicle door outer plate, and the air bag body is connected with the gas generator through an inflation pipe. The problem that a vehicle door invades inwards due to side collision is fundamentally solved; the air bag is arranged in the gap between the sheet metal parts of the inner and outer plates of the vehicle door, so that a large amount of development tests and cost can be saved, the response speed of the air bag is greatly increased, the side collision passenger protection effect is improved, and maintenance after accidents is facilitated.
本发明公开了一种安装在车门内部的气囊,主要包括安全气囊控制器、整车数据通讯总线、车门、气囊总成等;安全气囊控制器机气囊总成分别与整车数据通讯总线连接,气囊总成安装在车门内板钣金件与车门外板钣金件之间的空腔;气囊总成包括碰撞传感器、气体发生器及气囊袋体,碰撞传感器与整车数据通讯总线连接,气体发生器固定在车门内板与车门外板之间的空腔内,气囊袋体与气体发生器通过充气管连接。本发明从根本上解决侧面碰撞带来的车门向内侵入问题,将气囊装置在车门内外板钣金件的空隙中,因不会与人体发生接触,可以节省大量开发试验与成本,同时气囊响应速度也大幅提升,从而提升侧面碰撞乘员保护效果,也有利于事故后维修。
