The lower end of the mounting frame is fixed to the rear ends of the two groups of support plates 242. The cushion 244 is fixed to the upper end of the mounting frame 243.

[0032] When the mobility scooter is in use, the mounting frame and the back cushion 244 are arranged vertically, and the boss 2421 contacts the fixed cylinder 221, thereby limiting the back cushion 244 so that the back cushion 244 will not become loose when the user leans back on it. When the seat is folded, the support plate 242 is rotated around the rotating bracket 241 to make the back cushion 244 close to the seat assembly 21, saving storage space.

[0033] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
