[0019] In order to enhance the understanding of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0020] like Figure 1-7As shown, the present invention is a flip seat, comprising a fixed frame 1 and several movable frames 2, the fixing members on both sides of the movable frame 2 are fixed to the fixed frame 1 by screws and butterfly serrated washers, a finger-preventing guard plate 3 is arranged on the fixed frame 1 at the rear side of the movable frame 2, the front side surface of the guard plate 3 is an arc surface, a seat bottom box 4 is arranged at the lower end of the movable frame 2, the two sides of the seat bottom box 4 are fixed to the movable frame 2 by screws, a flip seat surface 5 is arranged on the upper surface of the movable frame 2, several cover plate support members 6 are installed on the fixing plate at the upper end of the fixed frame 1, the upper end of the cover plate support member 6 is fixed to the folding plate at the lower end of the inner C-shaped groove at the upper end of the cover plate 7 by screws, an outer C-shaped groove is arranged at the lower end of the cover plate 7, the fixing part of the upper end of the seat back 8 is fixed in the outer C-shaped groove, the seat back 8 is fixed to the fixed frame 1 by screws, and the surfaces of the seat back 8 and the flip seat surface 5 are provided with anti-slip biting protrusions. The thickness of the fixing portion at the upper end of the seat back 8 is thinner than that of the seat back 8, and the lower end of the fixing portion forms an angle with the upper end of the seat back 8. The surface of the fixing portion is curved, which is convenient for being stuck in the outer C-shaped groove at the lower end of the cover plate 7. The seat back 8 is positioned by the cover plate 7, which is convenient for installing the seat back 8. A downward curved portion is provided on the front side of the flip seat surface 5, and a groove is provided on the front side of the downward curved portion, which is not only beautiful, but also convenient for passengers to flip the seat downward.

[0021] The movable frame 2 includes a frame body 21 and fixings 22 arranged on both sides of the frame body 21. The frame body 21 and the fixings 22 are fixed on the same axis. A torsion spring 23 is arranged at both ends of the axis inside the frame body 21. One end of the torsion spring 23 is fixed on the axis, and the other end is fixed to the fixing column on the side of the frame column 21 by bolts. The middle part of the axis is connected to the movable end of the damping cylinder 24 fixed on the frame body 21. The opening and automatic closing of the seat are realized by the cooperation of the torsion spring 23 and the damping cylinder 24. A travel groove 221 with a travel angle of 88° is arranged on one side of the fixed axis of the fixing 22, and a convex column moving in the travel groove 221 is arranged on the frame body 21.
