Document Type and Number:
WIPO Patent Application WO/2021/103221
Kind Code:
A1
Abstract:
An opening and closing mechanism for front and rear legs of a frame, comprising a folding control assembly and a front and rear leg rotation assembly. The front and rear leg rotation assembly comprises: a rotation shaft (5) provided on a seat body (1) for use in rotationally connecting a front leg group (2) with the seat body; rear leg group support rods (501) used for connecting a rear leg group (3) with the seat body; and rear leg group rotation support rods (502) provided on the front leg group for use in connecting the rear leg group to the front leg group, so that the rear leg group rotates in reverse when the front leg group rotates about a rotation axis. When the front leg group is rotated and folded by the opening and closing mechanism, the rear leg group is able to be folded in reverse, so that the front leg group and the rear leg group are folded on two sides of the seat body, solving the defect in the prior art in which the seat body and the front and rear legs do not engage stably when the front and rear legs are folded on the same side. Further relating to a child safety seat, which comprises the seat body, the front leg group hinged to the seat body, the rear leg group hinged to the front leg group, and the opening and closing mechanism for front and rear leg groups of the frame.
