Title:
AUTOMATIC FOLDING SEAT
Document Type and Number:
WIPO Patent Application WO/2024/060887
Kind Code:
A1
Abstract:
The present utility model relates to the field of seats, and in particular to an automatic folding seat. The automatic folding seat comprises a seat body, a supporting structure, and elastic devices. First supports are hinged to the left ends of the bottom surfaces of the seat body, and second supports are hinged to the right ends of the bottom surfaces of the seat body. The elastic devices are hinged to the first supports and the second supports, the lower ends of the first supports are bent leftward, the lower ends of the second supports are bent rightwards, and pulleys are arranged at the lower ends of the first supports and the second supports. When the automatic folding seat changes from a folded state to an unfolded state, the first supports rotate leftward under the influence of weight, the second supports rotate rightward under the influence of weight, and the pulleys slide along with the first supports and the second supports until rotation angles of the first supports and the second supports relative to the seat body are maximized. When supporting legs are not completely opened and are in contact with the ground, since the supporting legs can be opened to a specific state due to the weight of a human body, during said period, the pulleys can reduce friction force with the ground, so that the supporting legs are not prone to damage.
