The invention relates to a passive safety system based on a zero-gravity seat, the passive safety system comprises a backrest quick return mechanism and a backrest position sensor control assembly which are mounted on a backrest angle adjuster, and the backrest position sensor control assembly comprises a switch pressing sheet fixedly connected to the backrest angle adjuster, a position sensor fixedly connected to a backrest connecting plate, and a control module fixedly connected to the switch pressing sheet. The switch pressing piece synchronously rotates along with the backrest angle adjuster, the position sensor is installed on a movement track line of the switch pressing piece, the position sensor is electrically connected with an exploder of the backrest quick return mechanism, and when the backrest angle adjuster drives the switch pressing piece to make contact with a normally-open contact of the position sensor, the position sensor transmits a communication signal to the exploder. The exploder can explode the backrest quick return mechanism only when receiving a communication signal of the position sensor and a collision signal of the automobile control platform at the same time; the device has the advantages that the position sensor and the backrest and cushion energy absorption unlocking mechanism supplement each other, and constraint protection of the backrest and cushion energy absorption unlocking mechanism is achieved.

    本发明涉及一种基于零重力座椅的被动安全系统,包括:安装在靠背调角器上的靠背快速回位机构和靠背位置传感器控制组件,靠背位置传感器控制组件包括:固连在靠背调角器上的开关压片、固连在靠背连接板上的位置传感器,开关压片随靠背调角器同步转动,位置传感器安装在位于开关压片的运动轨迹线上,位置传感器与靠背快速回位机构的点爆器电连接,当靠背调角器带动开关压片与位置传感器的常开触点接触后,位置传感器将连通信号传递给点爆器,点爆器只有同时接收到位置传感器的连通信号和汽车控制平台的碰撞信号才能点爆靠背快速回位机构;本发明的优点:位置传感器与靠背和坐垫吸能解锁机构相辅相成,实现靠背和坐垫吸能解锁机构的约束保护。
