The invention relates to a multifunctional seat backrest. A backrest side plate and a seat cushion are pivotally connected around A sitting and leaning rotating shaft, A backrest motor and A connecting rod mechanism are respectively arranged on the backrest side plate, the connecting rod mechanism comprises a first connecting rod and a second connecting rod which are pivotally connected, the firstconnecting rod is linked with the backrest motor, the second connecting rod is pivotally connected with the fixed bracket around a fixed rotating shaft, and the fixed bracket is fixed on a vehicle body; and when the position of the sitting and leaning rotating shaft is kept unchanged due to the fact that the seat cushion is static, the angle between the first connecting rod and the second connecting rod is changed through driving of the backrest motor so as to achieve the backrest adjusting function. When the position of the first connecting rod is kept unchanged due to the fact that the backrest motor is static, the angle between the first connecting rod and the second connecting rod is changed through movement of the sitting and leaning rotating shaft so as to achieve the sitting and leaning linkage function.
