摘要： A child safety seat comprising a base and a body rotatably connected to the base for providing a seating space. The base is rotatably connected to the body via a rotating shaft. The child safety seat further comprises an electrical pivoting structure including a base pivoting member for electrically connecting to a base electrical device in the base, and a body pivoting member for electrically connecting to a body electrical device in the body. The base pivoting member is coupled to the base and has a base conductive part. The body pivoting member is coupled to the body and has a body conductive part. The base conductive part and the body conductive part are rotatably and electrically connected in the rotating shaft. The base electrical device and the body electrical device are electrically connected to each other via electrical connection of the base conductive part and the body conductive part.

摘要： A side wing adjustment mechanism and an adjustable sitting device, the side wing adjustment mechanism includes: a pin arranged on the headrest; and a groove arranged on one of the side wings and including an inclined groove portion and a non-inclined groove portion. The pin is slidable along the inclined groove portion to adjust an extension distance of the one of the side wings and slidable along the non-inclined groove portion to adjust the height of the headrest relative to the backrest. The side wing can be folded and opened at will, and the structure of the application is more inclusive. During the opening and folding process, puling of the headrest or pushing of the side wing can be performed more smoothly and labor-savingly, and the phenomenon of deflection and jamming can be avoided, such that the opening and folding process of the side wings is smoother.

摘要： A side wing adjustment mechanism and an adjustable sitting device, the side wing adjustment mechanism includes: a pin arranged on the headrest; and an inclined grooves arranged on the side wing, a distance between a portion of the inclined grooves and the longitudinal center axis gradually decreases in a direction extending from bottom to top toward the headrest along a longitudinal center axis of the backrest, and the pin is slidable along the inclined grooves. According to the application, the side wing can be folded and opened at will, and the structure of the application is more inclusive. During the opening and folding process, puling of the headrest or pushing of the side wing can be performed more smoothly and labor-savingly, and the phenomenon of deflection and jamming can be avoided, such that the opening and folding process of the side wings is smoother.
