Thanks to the use of an original Ford solution, compatibility with the factory seat system is maintained, and predictable component behavior in emergency situations is ensured. The buckle's design is optimized for operation in the limited space between the center tunnel and the seat, minimizing the risk of collision with other interior elements.
