[0002] Seat slides are devices used in car seats that allow the seat to slide forward and backward while remaining locked, to accommodate the needs of different passengers and ensure safety during driving. This type of slide is usually installed between the car seat and the base, and the seat can be moved forward and backward through an unlocking mechanism while maintaining the stability of the seat.

[0003] However, in the existing technology, some seat rails have problems such as insufficient structural strength and poor operational flexibility, which affect the user experience and safety of the seat. To solve these problems, researchers have developed new technologies, such as a reversible rail with a double locking mechanism, which can improve the stability of the rail and the operational flexibility, thereby improving the overall performance of the seat.
