The zero-gravity seat framework comprises the backrest, a cushion, a front connecting rod, a front fixing support and a rear fixing support, the front end of the cushion is hinged to the upper end of the front connecting rod, the zero-gravity seat framework further comprises a zero-gravity connecting rod, the front end of the zero-gravity connecting rod is hinged to the lower end of the front connecting rod, and the rear end of the zero-gravity connecting rod is hinged to the rear fixing support. The rear end of the zero-gravity connecting rod is hinged to the front end of the zero-gravity lead screw motor, and the middle of the zero-gravity connecting rod is hinged to the front fixing support. The lower end of the backrest is hinged to the rear fixing support, the rear end of the cushion is hinged to the lower portion of the backrest, and the hinge point is located above the fixed hinge point of the backrest. The seat cushion and the backrest are hinged, share one set of connecting rod mechanism and are provided with respective driving assemblies, so that the two functions of zero gravity and linkage of backrest turnover and seat cushion diving exist in one set of connecting rod structure at the same time, the occupied space of structural arrangement is small, the comfort requirement of people in the zero-gravity state is met, and the comfort of the people in the zero-gravity state is improved. And the large space requirement of placing the luggage case under the state that the backrest is turned flat is also met.

    本发明公开了一种靠背可向前翻平的零重力座椅骨架,包括靠背、坐垫、前连杆、前固定支架以及后固定支架,坐垫的前端与前连杆的上端铰接,还包括零重力连杆,零重力连杆的前端与前连杆的下端铰接,零重力连杆的后端与零重力丝杆电机的前端铰接,且零重力连杆的中部铰接于前固定支架上;靠背下端铰接于后固定支架上,且坐垫的后端铰接于靠背下部,其铰接点位于靠背的固定铰接点上方。通过将坐垫与靠背铰接,共同使用一套连杆机构并配备有各自的驱动组件,实现零重力和靠背翻平联动坐垫下潜这两种功能同时存在于一套连杆结构中,结构布置占用空间小,既满足了人们零重力状态下的舒适性要求,也满足了靠背翻平状态下行李箱放置的大空间需求。
