AI Technical Summary
Traditional flip-up seat cushions require space to be reserved during use and storage, taking up a lot of space and resulting in low space utilization.
The four-bar linkage design restricts the positional relationship of the hinge points (A>B>D), allowing the seat to flip forward and upward or backward and downward during rotation, eliminating the need for the user to leave room for rotation. Combined with torsion springs and limit rods, it ensures smooth operation of the seat during rotation.
It achieves the goal of requiring no space to be reserved during the seat flipping process, with a simple structure and small footprint, thus improving space utilization and user comfort.
