The invention provides a seat backrest adjusting mechanism and a seat. The seat backrest adjusting mechanism comprises an adjusting part, a locking part and an unlocking part, wherein the adjusting part and the locking part are arranged on a cushion framework, and the unlocking part is arranged between the adjusting part and a backrest framework; the adjusting part is connected with the backrest framework through an angle adjuster, an elastic part is arranged between the adjusting part and the cushion framework, and the elastic part is used for driving the rotated adjusting part to return; the locking part is used for locking the adjusting part and is driven to rotate along with the backrest framework, the unlocking part can pull the locking part to act so as to unlock the adjusting part, and the adjusting part and the backrest framework can synchronously rotate downwards relative to the cushion framework under the driving of the gravity of the seat backrest, so that the elastic part stores energy. According to the seat backrest adjusting mechanism, the angle of the seat backrest can be adjusted, meanwhile, the height difference between the seat backrest and the cushion after the seat backrest is laid flat can be eliminated, and therefore the use comfort of the seat backrest when the seat backrest is laid flat can be improved.

    本发明提供了一种座椅靠背调节机构及座椅,本发明所述的座椅靠背调节机构包括设于坐垫骨架上的调节部与锁止部,以及设于调节部和靠背骨架之间的解锁部;调节部通过调角器与靠背骨架相连,调节部和坐垫骨架之间设有弹性部,弹性部用于驱使转动后的调节部回位;锁止部用于锁止调节部,且随靠背骨架被驱使转动,解锁部能够牵引锁止部动作,而解除对调节部的锁止,并因座椅靠背的重力驱使,调节部与靠背骨架能够相对于坐垫骨架同步向下转动,以使弹性部蓄能。本发明所述的座椅靠背调节机构,在满足座椅靠背角度调节的同时,还利于消除座椅靠背在放平后与坐垫之间的高度差,从而利于提高座椅靠背在放平时的使用舒适性。
