• preserving the factory safety level for transported passengers,
• proper interaction with the factory mountings and seat structure in the BMW X5 E70.

• precise fit to the seat structure in the third row of seats,
• compatibility with the original seat belt on the rear left side,
• retention of factory mounting points without the need for modifications or adaptations.

Original manufacturing allows for installation in the location intended by the manufacturer, maintaining the correct belt routing geometry and proper operation of the fastening mechanism.
