The invention discloses a seat backrest assembly of a vehicle seat, the vehicle seat and a vehicle, the seat backrest assembly of the vehicle seat comprises an upper seat backrest framework and a lower seat backrest framework, the upper end of the lower seat backrest framework is connected and matched with the lower end of the upper seat backrest framework, and the lower end of the lower seat backrest framework is connected and matched with the lower end of the lower seat backrest framework; the upper seat backrest framework is suitable for rotating relative to the lower seat backrest framework; the deformable driving part is used for driving the upper seat backrest framework to rotate relative to the lower seat backrest framework through deformation of the driving part. Therefore, the backrest framework is divided into the upper seat backrest framework and the lower seat backrest framework, the driving piece is made to stretch and deform to drive the upper seat backrest framework to rotate relative to the lower seat backrest framework, and the upper seat backrest framework can be attached to the shoulders of a user after being adjusted to a proper angle relative to the lower seat backrest framework. The shoulders of the user can be effectively supported in the riding process, so that the riding comfort of the vehicle can be improved, and the use experience of the vehicle can be improved.
本发明公开了一种车辆座椅的座椅靠背组件、车辆的座椅以及车辆,车辆座椅的座椅靠背组件包括:上座椅靠背骨架和下座椅靠背骨架,下座椅靠背骨架的上端与上座椅靠背骨架的下端连接配合,上座椅靠背骨架适于相对下座椅靠背骨架转动;可形变的驱动件,通过驱动件形变驱动上座椅靠背骨架相对下座椅靠背骨架转动。由此,通过将靠背骨架分割为上座椅靠背骨架和下座椅靠背骨架,并且使驱动件伸缩变形驱动上座椅靠背骨架相对下座椅靠背骨架转动,上座椅靠背骨架相对下座椅靠背骨架调节至适宜的角度后可以与用户的肩部贴合,与现有技术相比,用户在乘车过程中肩部可以获得有效地支撑,从而可以提高车辆的乘坐舒适性,进而可以提高车辆的使用体验。
