The invention discloses a headrest and chair back coupling mechanism and a child safety seat. The headrest and chair back coupling mechanism comprises a chair body and a headrest, the headrest is located at the inner side of the chair body, a gear slot group and two first guiding grooves are longitudinally distributed in the chair body, a movable gear shaft is arranged on the headrest corresponding to the gear slot group, a second guiding groove is formed in the rear side of the gear shaft of the headrest, the gear shaft corresponds to each gear slots in the gear slot group, a first coupling part fixed to the lower part of the headrest penetrates through the first guiding groove of the chair body and uses a first limiting part for horizontal limiting, a second coupling part fixed to the upper part of the chair back penetrates through the second guiding groove of the headrest and uses a second limiting part for horizontal limiting, thus the stability of the coupling between the headrestand the chair back, and meanwhile the guiding effect of headrest movement is achhieved; and when the headrest moves upward relative to the chair body, the first coupling part moves upwards along thefirst guiding groove, and the second coupling part and the second guiding groove generate relative displacement to achieve the headrest height adjustment.
Description
technical field [0001] The invention relates to a child safety seat, in particular to a headrest and seat back coupling mechanism of the child safety seat. Background technique [0002] Usually, a headrest is provided inside the seat back of the child safety seat, and a height adjustment mechanism is provided between the headrest and the seat back to facilitate the raising or lowering of the headrest height of the child safety seat for vehicles. , the head protection position of the child seat should also be raised accordingly, so that the child's head can be better protected. At present, the headrest adjustment devices of child safety seats on the market are either complicated in structure or very inconvenient to operate. There is also a headrest adjusting device, which needs to be equipped with a relatively complicated mechanism in order to achieve the purpose of easy operation. The above-mentioned headrest height adjustment mechanism requires the coordinated operation o...
