Purpose and vehicle placement

The presented seat belt is designed for installation in the front part of the cabin, on the left side. It is responsible for stably holding the driver in the seat during driving and in emergency situations, working in conjunction with the factory mounting points in the vehicle body.

Thanks to a design consistent with the solutions used by the vehicle manufacturer, the belt maintains the correct webbing routing geometry, which reduces the risk of incorrect positioning on the user's chest and hips.

Technical and functional characteristics

As an element from the Seat belts and parts category, the product includes a complete seat belt mechanism designed to work within the factory safety system. The applied design enables:

• proper retraction and extension of the webbing under typical driving conditions,
• locking of the webbing movement during sudden braking or changes in speed,
• compatibility with original mounting points in the body and seat.

This solution allows for maintaining consistency with other elements of the passive safety system, which is important both from the point of view of user protection and compliance with the vehicle's design assumptions.

Benefits of using an original seat belt

Using an original seat belt in a Mercedes W207 Coupe provides a number of practical benefits:

• Factory fit – compatibility with the seat, pillar, and mounting structure, with no modifications required.
• Consistency with the safety system – predictable operation in combination with other system components.
• Stable webbing routing – reduction of the risk of twisting and improper positioning while driving.

A used OEM component is a solution that allows for maintaining an appropriate level of safety while reducing repair costs compared to new parts.
