The invention discloses an auxiliary restraint system of a zero-gravity seat, which comprises the zero-gravity seat and a restraint device, the zero-gravity seat comprises a seat body with a backrest, a seat cushion and armrests, a backrest gunpowder explosion device is mounted in the backrest, and a seat cushion gunpowder explosion device is mounted in the seat cushion; the restraining device comprises a sensor unit, an information processing unit and a decision-making unit. The sensor unit monitors automobile surrounding state information in real time and sends the information to the information processing unit. The information processing unit calculates a TTC numerical value according to the automobile surrounding state information sent by the sensor unit and sends the TTC numerical value to the decision-making unit; and the decision-making unit is used for judging whether collision is about to occur or not according to the TTC numerical value, so that the system enters an activated state, and the backrest gunpowder explosion device or the cushion gunpowder explosion device is detonated according to the collision type. The system can respond to collision in an extremely short time, and provides more comprehensive protection for passengers by intelligently adjusting the posture of the seat and combining with an existing safety belt restraint system.
本发明公开一种零重力座椅的辅助约束系统,其包括零重力座椅和约束装置,零重力座椅包括具有靠背、坐垫和扶手的座椅本体,靠背内部安装有靠背火药爆炸装置,坐垫内部安装有坐垫火药爆炸装置;约束装置包括传感器单元、信息处理单元和决策单元,传感器单元实时监测汽车周围状态信息并发送至信息处理单元;信息处理单元根据传感器单元发送的汽车周围状态信息来计算TTC数值,并发送至决策单元;决策单元用于根据TTC数值判断是否有碰撞即将发生,使系统进入激活状态,并根据碰撞类型来引爆靠背火药爆炸装置或者坐垫火药爆炸装置。该系统能够在极短的时间内响应碰撞,通过智能调整座椅姿态,与现有的安全带约束系统相结合,为乘员提供更全面的保护。
