The invention discloses a leg support and cushion linkage adjusting mechanism which comprises an upper seat frame, a seat frame base, a front connecting rod, a rear connecting rod, a driving motor and a leg support lifting assembly, the front connecting rod, the upper seat frame, the rear connecting rod and the seat frame base are sequentially connected to form a first four-connecting-rod mechanism, and the leg support lifting assembly comprises a first leg support rod, a second leg support rod and a leg support panel. The leg supporting panel is fixedly installed in front of the first leg supporting rod, and the first leg supporting rod, the second leg supporting rod, the front connecting rod and the seat frame base are sequentially connected to form a second four-connecting-rod mechanism. When the cushion is adjusted backwards, the leg support is opened, and when the cushion is adjusted forwards, the leg support can also be retracted to the initial position; a set of four-connecting-rod mechanism is used in the leg support structure, the driving rod mechanism is fixedly connected with a front connecting rod of the cushion height adjusting mechanism, and the leg support is opened and closed through linkage with the cushion height adjusting mechanism, so that the leg support structure is simplified, and the space arrangement is simple; the leg support adjusting mechanism and the cushion height adjusting mechanism share one driving motor, so that the cost is reduced.

    本发明公开了一种腿托与坐垫联动调节机构,包括上座框、座框底座、前连杆、后连杆、驱动电机以及腿托抬升总成,前连杆、上座框、后连杆以及座框底座依次相连构成第一四连杆机构,腿托抬升总成包括第一腿托杆、第二腿托杆以及腿托面板,腿托面板固定安装在第一腿托杆前方,第一腿托杆、第二腿托杆、前连杆以及座框底座依次相连构成第二四连杆机构。实现坐垫向后调节时腿托打开,并且当坐垫向前调节时,同样能收回至初始位置;此腿托结构中使用了一套四连杆机构,驱动杆机构与坐垫调高机构前连杆固连,通过与坐垫调高机构联动,实现腿托打开与闭合,简化腿托结构,空间布置简单;腿托调节和坐垫调高机构共用一个驱动电机,降低成本。
