The invention provides a vehicle seat backrest, a vehicle seat and a vehicle. The vehicle seat backrest comprises a backrest framework and an angle adjuster assembly, the backrest framework comprises a carbon fiber outer layer and a foam inner core, the foam inner core is wrapped by the carbon fiber outer layer to form a core wrapping structure, the backrest framework further comprises a backrest body, a first side wall and a second side wall, and the first side wall and the second side wall are connected to the two sides of the backrest body respectively and are oppositely distributed; at least one of the backrest body, the first side wall and the second side wall is of a core-wrapped structure. The angle adjuster assembly is connected between the first side wall and the second side wall. Thus, the carbon fiber outer layer can effectively increase the rigidity of the backrest framework, the foam inner core can reduce the number of carbon fiber laying layers, the forming efficiency of the carbon fiber outer layer is effectively improved while the weight is reduced, and natural edge transition and continuous carbon fiber lines after the foam inner core is wrapped by the carbon fiber outer layer are facilitated; the carbon fiber outer layers on the inner side and the outer side of the backrest framework can be exposed without cutting hands.
本发明提供一种车辆座椅靠背、车辆座椅和车辆。车辆座椅靠背包括靠背骨架以及调角器组件,靠背骨架包括碳纤维外层和泡沫内芯,碳纤维外层包裹泡沫内芯形成包芯结构,靠背骨架还包括靠背主体、第一侧围以及第二侧围,第一侧围与第二侧围分别连接于靠背主体的两侧且相对分布,靠背主体、第一侧围、第二侧围中的至少一个为包芯结构。调角器组件连接于第一侧围与第二侧围之间。如此,碳纤维外层能够有效地增加靠背骨架的刚度,而泡沫内芯能够减少碳纤维铺层数量,在减重的同时有效地提高碳纤维外层的成型效率,有助于碳纤维外层包裹泡沫内芯后的边缘过渡自然,碳纤维纹路连续,靠背骨架内外侧的碳纤维外层均可裸露而不割手。
