The invention relates to a zero-gravity seat crumple mechanism based on passenger protection and a control method of the zero-gravity seat crumple mechanism. Comprising a seat basin framework, a seat cushion framework with one end hinged to the seat basin framework, a connecting rod seat cushion angle adjusting mechanism installed between the seat basin framework and the seat cushion framework and used for adjusting the angle of the seat cushion framework, and a seat cushion crumple mechanism installed on the connecting rod seat cushion angle adjusting mechanism and used for enabling the seat cushion framework to rapidly return to the initial position after automobile collision. The cushion airbag protection device is popped up to support and protect legs of a passenger after the automobile is collided; the seat has the advantages that the seat cushion crumple mechanism and the seat cushion air bag protection device which have a synergistic effect are additionally arranged, so that after the seat in a zero-gravity posture is collided, the lower end of the seat cushion crumple and absorbs energy through the seat cushion crumple mechanism, and the seat cushion framework quickly returns to the initial position; the upper end of the cushion is subjected to air bag explosion, after the air bag is inflated, sufficient support is provided for the thighs of the passenger, and the sitting posture is optimized to improve restraint protection for the passenger.
本发明涉及一种基于乘员防护的零重力座椅溃缩机构及其控制方法,包括:坐盆骨架、一端铰接在坐盆骨架上的坐垫骨架、安装在坐盆骨架与坐垫骨架之间用于坐垫骨架角度调节的连杆坐垫角度调节机构、安装在连杆坐垫角度调节机构上用于汽车碰撞后使坐垫骨架快速回位至初始位置的坐垫溃缩机构、以及用于汽车碰撞后弹出对乘员腿部进行支持保护的坐垫气囊保护装置;本发明的优点是:增加协同作用的坐垫溃缩机构和坐垫气囊保护装置,使零重力姿态的座椅在发生碰撞后,坐垫下端通过坐垫溃缩机构进行溃缩吸能,使坐垫骨架快速回位至初始位置;并且坐垫上端进行气囊点爆,气囊充气后,对乘员大腿提供足够支撑,实现优化坐姿来提高对乘员的约束保护。
