This drawing shows the basic mechanism of the foldable passenger seat design. The passenger seat is divided into two main components: the backrest and the seat. The backrest can be folded down to create additional storage space when the seat is not in use. When a second passenger is needed, the backrest can be lifted up and secured in place using latches or a locking mechanism. The partition separates the passenger seat from the driver's seat, providing privacy and safety for both occupants.
