The invention discloses a backrest adjusting mechanism and a child safety seat, and relates to the technical field of child cars, the backrest adjusting mechanism comprises a fixed seat fixedly mounted in the middle of the back side of a backrest, and the two opposite sides of the fixed seat are each provided with a sliding rod in a sliding mode; the two sliding rods are each provided with a rotating piece in a rotating mode, and the two rotating pieces are fixedly connected with the two protection wings in a one-to-one correspondence mode. And the adjusting assembly is assembled to be capable of driving the two sliding rods to synchronously slide and fold in the reverse direction and driving the two rotating pieces to synchronously rotate and fold in the reverse direction. According to the backrest adjusting mechanism provided by the invention, the distance between the two protective wings on the backrest is adjustable, and the included angle between the two protective wings up to now is adjustable, so that the backrest adjusting mechanism can adapt to children with different weights, the children are well wrapped, and the protection effect on the children is improved; and the adjusting interval can simultaneously drive the two sliding rods to slide and fold synchronously and reversely and drive the two rotating parts to rotate and fold synchronously and reversely, so that the adjustment is convenient.

    本发明公开了一种靠背调节机构及儿童安全座椅,涉及儿童汽车技术领域,包括固定安装在椅背的背侧中部的固定座,所述固定座的相对两侧各滑动设置有一滑动杆;两所述滑动杆上分别转动设置有一转动件,两所述转动件与两所述护翼一一对应地固定连接;还包括调节组件,调节组件被装配为能够驱动两个滑动杆同步逆向滑动合拢以及两个转动件同步逆向转动合拢。本发明提供的靠背调节机构,椅背上的两护翼的间距可调,两护翼至今的夹角可调,以能够适配不同胖瘦的儿童,对儿童形成很好的包裹性,提高对儿童的保护效果;并且调节区间能够同时驱动两个滑动杆同步逆向滑动合拢以及两个转动件同步逆向转动合拢,调节方便。
