The invention discloses an object-carrying chair back for an automobile seat. The object-carrying chair back comprises a back main body, at least one object carrying plate rotationally connected with the back main body, and an overturning control mechanism; the overturning control mechanism comprises a lifting unit and a swinging connecting piece which is rotationally connected with the lifting unit and is in sliding connection with the loading plate; during use, the lifting unit ascends and descends to enable the swing connecting piece to slide along the back main body, and therefore the object carrying plate is driven to turn over to the back main body. The lifting unit ascends and descends to enable the swing connecting piece to extend towards the outer side of the back main body, so that the object carrying plate is driven to overturn to the back main body, and overturning movement of the object carrying plate is achieved. Compared with the prior art, the control structure is simple and stable, a triangular structure is formed by the connecting position of the object carrying plate and the back main body, the connecting position of the swing connecting piece and the lifting unit and the connecting position of the swing connecting piece and the object carrying plate, and the stability of the structure and control is improved.
本发明所述的用于汽车座椅的可载物椅背,包括背部主体、至少一个与背部主体转动连接的载物板、以及翻转控制机构;所述翻转控制机构包括升降单元、及与升降单元转动连接且与载物板滑动连接的摆动连接件;使用时,升降单元升降使摆动连接件沿背部主体滑动,从而带动载物板翻转于背部主体。本发明通过升降单元升降使摆动连接件向背部主体外侧伸展,从而带动载物板翻转于背部主体的方式,实现载物板的翻转运动。相比于现有技术,本发明中的控制结构简单且稳定,而且,载物板与背部主体、摆动连接件与升降单元、摆动连接件与载物板三个连接处构成三角形结构,增加了结构和控制的稳定性。
