According to the technical scheme, a connecting piece connected to an adjusting belt is arranged at the end of the adjusting belt, the connecting piece is arranged on a guiding piece in a sliding mode, when a frame needs to be folded, a cloth cover on a backrest can pull the adjusting belt, so that the connecting piece is driven to slide upwards along the guiding piece, and the backrest can be folded. Meanwhile, when the inclination angle of the backrest needs to be adjusted, the locking length of the adjusting belt is shortened through the adjusting part until the inclination angle is adjusted to the shortest fixed length, and at the moment, the end of the adjusting belt can drive the connecting piece to slide downwards along the guiding piece, so that the backrest is further inclined upwards; according to the invention, the backrest can not be restrained by the adjusting belt in the folding process, so that the folding process is not influenced; in the process of adjusting the inclination angle of the backrest, the inclination angle of the backrest cannot be restrained by the adjusting belt, and adjustment of the inclination angle of the backrest is not affected.
本发明公开了一种童车的靠背调节机构及具有其的童车,本发明技术方案在调整带的端部设有连接于其的连接件,连接件可滑动地设于引导件上,在需要收合车架时,靠背上的布套会拉动调整带,从而带动连接件沿引导件向上滑动,调整带不会产生约束,从而不影响车架的收合,同时,在需要调节靠背的倾角时,调整带通过调整部件缩短锁定长度,直至调整至最短定长度,此时调整带的端部会带动连接件沿引导件向下滑动,使靠背进一步向上倾斜,使靠背实现较为直立的角度调整,本发明在收车过程中不会被调整带约束,不影响收车;在调节靠背的倾角过程中不会被调整带约束,不影响调节靠背的倾角,具有有益的技术效果。
