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. According to the multifunctional seat backrest, the functions of slouch and independent backrest adjustment can be achieved at the same time through the connecting rod mechanism, and diversified requirements of customers are met.
本发明涉及一种多功能座椅靠背,靠背侧板与座椅坐垫围绕着坐靠旋转轴枢转连接,靠背电机和连杆机构分别被安装在靠背侧板上,连杆机构包括枢转连接的第一和第二连杆,第一连杆与靠背电机联动,第二连杆与固定支架围绕着固定旋转轴枢转连接,固定支架被固定在车身上;当坐靠旋转轴由于座椅坐垫静止而保持位置不变时,第一连杆和第二连杆之间的角度通过靠背电机的驱动而发生变化以实现靠背调节功能;在第一连杆由于靠背电机的静止保持位置不变时,第一连杆和第二连杆之间的角度通过坐靠旋转轴的移动而发生变化以实现坐靠联动功能。根据本发明的多功能座椅靠背,通过连杆机构能够同时实现slouch和单独靠背调节功能,满足客户的多样化需求。
