Why Can't Manual Seats Move Forward and Backward?

[McJourney]

Manual seats cannot move forward and backward due to: 1. Rust on the manual tracks; 2. Detachment of the manual tracks. The solutions are: 1. Spray rust remover, pull the lever, and move back and forth to check mobility; 2. Reattach the detached tracks with screws. Car seats are seating used when riding in a vehicle, categorized by function into: fixed, removable, and adjustable; and by passenger capacity into: single, double, and multiple. The basic requirements for car seats are: 1. The arrangement of seats within the entire cabin should be reasonable, especially the driver's seat must be in the optimal position; 2. The design of the seat must conform to human physiological functions, striving for aesthetics while ensuring comfort; 3. Seats must be safe and reliable, with sufficient strength, stiffness, and durability, compact in structure and minimizing weight as much as possible; 4. Various adjustment mechanisms provided for the comfort of drivers and passengers must have reliable locking devices to ensure safety.
