The invention relates to a backrest quick return mechanism and cushion quick return mechanism based on a zero-gravity seat, which comprises a backrest framework positioned at the back of the seat and a cushion framework positioned at the cushion of the seat, the backrest framework is rotatably connected to the cushion framework through angle adjusters on two sides, and the backrest framework is rotatably connected to the cushion framework through angle adjusters on two sides. A brushless angle adjusting motor used for adjusting the angle of an angle adjuster is installed on the backrest framework, a backrest quick return mechanism is installed between the backrest framework and the angle adjuster, the rear end of the cushion framework is hinged to a bottom seat sliding rail, and the angle of the cushion framework is adjusted at the front end of the cushion framework through a front angle adjusting mechanism. The seat cushion quick return mechanism is mounted on the front angle adjusting mechanism, and the backrest quick return mechanism and the seat cushion quick return mechanism are the same in structure. The seat has the advantages that through the quick return mechanism, when the seat is collided at the zero-gravity posture position, the backrest and the seat cushion can quickly return, so that the restraint protection on passengers is improved, and the injury caused by collision is reduced.
本发明涉及一种基于零重力座椅的靠背快速回位机构、坐垫快速回位机构,包括:位于座椅背部位置的靠背骨架、以及位于座椅坐垫位置的坐垫骨架,靠背骨架通过两侧的调角器转动连接在坐垫骨架上,靠背骨架上安装有用于调节调角器角度的无刷调角电机,靠背骨架与调角器之间安装有靠背快速回位机构,坐垫骨架的后端铰接在底部座椅滑轨上,坐垫骨架的前端通过前部角度调节机构进行坐垫骨架角度调节,前部角度调节机构上安装有坐垫快速回位机构,靠背快速回位机构与坐垫快速回位机构的结构相同。本发明的优点:通过快速回位机构机构,使座椅在零重力姿态位置发生碰撞时,靠背与坐垫能够快速回位,提高对乘员的约束保护,减少碰撞产生的伤害。
