Detailed Description

The technical solution of the present invention is further explained with reference to the drawings and the specific embodiments.

In the following, the terms of orientation such as "up", "down", "left", "right", "front", "rear", etc. are defined with reference to the user's face oriented in the "front" direction when the user sits on the folding seat.

Referring to the drawings, a folding seat is shown, which has an unfolded state and a folded state, and comprises a seat plate 1 extending along the front-back direction, two sets of side plates 2 respectively arranged at the left and the right sides of the seat plate 1, a back plate 3 positioned at the back of the seat plate 1, and a connecting frame 4 arranged between the front parts of the two sets of side plates 2, wherein the seat plate 1, the side plates 2 and the back plate 3 enclose a space for a user to sit on, each set of side plates 2 comprises an upper side plate 21 and a lower side plate 22 sequentially arranged along the up-down direction, the lower part of the upper side plate 21 is rotatably connected with the upper part of the lower side plate 22 around a first axis a extending along the front-back direction, the lower part of the lower side plate 22 is rotatably connected with the seat plate 1 around a second axis b extending along the front-back direction, the lower part of the back plate 3 is rotatably connected with the rear part of the seat plate 1 around a third axis c extending along the left-right direction, the connecting frame 4 is rotatably connected between the front parts of the two sets of the upper side plates 21, referring to fig. 10 to 15, when the folding seat is in the folded state, the back plate 3 is folded over the seat plate 1, and the upper side plate 21 and the lower side plate 22 are rotated about the first axis a and stacked over the back plate 3. In this embodiment, the folding seat is a child booster seat.

Specifically, referring to fig. 10 to 12, when the folding seat is in the folding state, the two sets of side plates 2 are folded and folded side by side in the left-right direction above the back plate 3, and when the folding seat is converted from the unfolding state to the folding state, the two sets of lower side plates 22 are rotated in opposite directions and folded on the back plate 3, and the two sets of upper side plates 21 are correspondingly stacked and folded above the lower side plates 22 on the corresponding sides. In the present embodiment, referring to fig. 13 to 15, when the folding seat is in the folded state, the two sets of side plates 2 are arranged at a distance in the left-right direction, and the upper side plate 21, the lower side plate 22, the back plate 3, and the seat plate 1 are parallel to each other.
