[0030] The utility model will be further described in specific embodiments in combination with the drawings, referring to Figure 1 — Figure 3 :

[0031] A double-person hanging foldable seat, comprising two groups of mounting supports 1 fixed to the side wall of a vehicle body, the top of each of the two mounting supports 1 is hinged with a reinforcing link 2, the front side of each of the two reinforcing links 2 is hinged with a seat base 3, and a reset torsion spring 20 is arranged in the hinged end, the seat base 3 comprises a crossbar 30, the front side of the crossbar 30 is fixed with an arc-shaped bar 31, the arc-shaped bar 31 and the crossbar 30 form the shape of a double-person seat, the rear side of the crossbar 30 is fixed with a hinged seat 32 hinged with the front side of the reinforcing link 2, a seat cushion 4 is sleeved on the seat base 3, the crossbar 30 is provided with a back canvas 5, the top of the back canvas 5 is provided with a hook 7 hung on the side wall of the vehicle body, the two ends of the arc-shaped bar 31 are provided with triangular canvases 6, one side of each of the triangular canvases 6 is fixedly connected with the back canvas 5, and the top of each of the triangular canvases 6 is fixedly connected with the hook 7.

[0032] Generally, in the state of non-use, the seat base is reset by the reset torsion spring 20 through the hinged seat 32, so that the seat base rotates and lifts along the hinged seat 32, thereby saving the space in the vehicle.

[0033] In the state of use, the user overcomes the reset torsion spring 20 and presses the seat base 3 downward, so as to realize the riding, and the tight support of the back canvas and the triangular canvas ensures that the user will not fall off when riding.

[0034] The supporting parts of the seat are located at the mounting supports and the hooks, both of which are located on the side wall, and the hook 7 can be quickly disassembled, so that the overall structure is simple and convenient to fix.

[0035] In the above structure, the triangular canvas is a right-angled triangle, and the right-angled side is sewn with the front side of the backrest canvas 5, thereby playing a fixed role; the bottom of the triangular canvas and the backrest canvas is fixed on the side of the seat base frame by bolts.

[0036] In addition, the bolts or fixing members on the side wall of the seat base frame are in the form of integral molding or bolt tapping installation, and the edge of the canvas is provided with a certain installation hole, thereby facilitating installation and fixation.

[0037] Preferably, the middle part of the arc-shaped rod 31 and the middle part of the cross rod 30 are provided with a reinforcing rod 33, and the reinforcing rod 33 is fixedly connected with the triangular canvas 6. Since double-occupancy is adopted, the reinforcing rod 33 can provide stronger support for the overall seat base frame, and the reinforcing rod is in the form of integral welding and is also connected with the triangular canvas, thereby supporting the middle part of the seat.

[0038] The number of the triangular canvases is three, and they are respectively located at left, middle and right positions, thereby supporting and balancing the three positions, and hooks 7 are arranged at the top of the three positions, so that the top of the three triangular canvases can also be quickly disassembled and hung.

[0039] Preferably, safety belts 60 are arranged between the bottoms of the two adjacent triangular canvases 6, thereby ensuring safety during occupancy.

[0040] Preferably, a backrest cushion 50 is fixed to the rear side of the backrest canvas 5, thereby providing comfort for the back during occupancy.

[0041] Preferably, the cross rod 30, the arc-shaped rod 31, the reinforcing rod 33 and the hinged seat 32 are fixed by welding, thereby ensuring the overall strength and providing convenience for production and manufacturing.

[0042] Preferably, the hinged seat 32 comprises two parallel hinged plates 320, and a hinge column 321 is arranged between the two hinged plates 320, the hinge column 321 is sleeved with the reset torsion spring 20, and a limiting gap 322 is formed below the hinged plate 320, and the two ends of the reset torsion spring 20 are embedded in the limiting gap 322 of the two hinged plates 320.

[0043] The above structure enables the hinged plate to be locked by the limiting gap 322 when the hinged plate and the reinforcing connecting rod are at 180 degrees, thereby preventing the seat base frame from being excessively bent downward, ensuring normal occupancy, and relieving the pressure of the hook 7.

[0044] Preferably, the hinge column 321 comprises a column body, and a limiting end face 323 is arranged on one side of the column body.

[0045] In the above structure, the hinge column 321 arranged between the two hinge plates 320 cannot rotate, so that the reset torsion spring 20 can only rotate for resetting and cannot rotate with the hinge column 321.

[0046] The above embodiments are only preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
