The backrest limiting assembly comprises two side protection frames located on the left side and the right side, a top protection frame located on the upper side and a backrest frame located on the rear side, the top protection frame can be connected between the side protection frames and the backrest frame in a pivoted mode, and in addition, the top protection frame can be connected between the side protection frames and the backrest frame in a pivoted mode. The side protection frames and the backrest frame are pivoted to the frame through an upper pivot and a lower pivot respectively, so that the side protection frames, the top protection frame, the backrest frame and the frame form a four-rod mechanism, the backrest frame is provided with two side parts located on the left side and the right side, and at least one side part coincides with the side protection frame on the corresponding side in the vertical direction; therefore, the side part of the backrest frame can be blocked by the part, pivoted with the frame, of the side protection frame when the side part of the backrest frame forwards pivots around the lower pivot to a preset position. According to the backrest limiting assembly of the buggy disclosed by the invention, the backrest of the seat can be limited, the backrest is prevented from exceeding the frame main body during forward inclination adjustment, and the safety coefficient of the buggy is higher.

    本公开提供了一种儿童车的背靠限位组件和儿童车,背靠限位组件包括位于左右两侧的两个侧护架、位于上侧的顶护架和位于后侧的背靠架,其中,顶护架能够枢转地连接于侧护架与背靠架之间,而且,侧护架和背靠架分别经由上枢轴和下枢轴枢接于车架,使得侧护架、顶护架、背靠架和车架构成一个四杆机构,其中,背靠架具有位于左右两侧的两个侧部,至少一个侧部和对应一侧的侧护架沿竖向重合,从而使得背靠架的该侧部在围绕下枢轴向前枢转到预设位置时会被侧护架的与车架枢接的部位阻挡。根据本公开的儿童车的背靠限位组件可以对座椅的背靠进行限位,避免背靠前倾调节时超出车架主体,使得儿童车的安全系数更高。
