• Factory mounting geometry ensuring correct belt guidance relative to the seat and pillar.
• Locking mechanism that responds to overloads and sudden changes in speed.

Using an original seat belt helps maintain the vehicle's technical integrity and avoids fitting issues that can arise with universal parts or aftermarket replacements of uncertain origin.
