The specified location on the vehicle as front – left side allows for unambiguous selection of the part for a specific mounting position, which reduces the risk of errors in part selection.

• Compatibility with Vehicle Systems – the belt is designed for the specific structural solutions of the Seat Ateca FR body and interior.
• Predictable Performance – maintaining locking characteristics in line with the manufacturer's specifications.
• Professional Repair Outcome – replacing a damaged part with an original component from the same category allows for the restoration of the original level of passive safety.

Part Condition and Installation Aspects

The seat belt is offered as an original used part, allowing for an economical restoration of the system's functionality while maintaining the factory design. Before installation, a standard verification of the retractor mechanism's correct operation and a check of the vehicle's mounting points are recommended.

Due to its front left-side placement, installation should be performed in accordance with the manufacturer's procedures, particularly regarding the tightening torques of the mounting bolts and the routing of the webbing relative to the seat and pillar.
