Purpose and function in the vehicle

The presented seat belt has been designed for the rear part of the body, with the possibility of installation on both the left and right sides. Thanks to this, it can serve as a replacement element in case of wear, damage, or activation of the locking mechanism after a collision. The design, consistent with the solutions used by Mercedes, allows for the preservation of factory mounting points and the correct routing of the webbing relative to the seat and the body.

Construction and performance parameters

The seat belt belongs to the Seat belts and parts category, which means it is an element responsible for keeping the passenger in the seat during sudden braking or impact. The black webbing is color-matched to typical interior configurations of W177 models, and the materials used are resistant to stretching and abrasion under typical operating conditions.

The retractor mechanism has been constructed to ensure smooth extension and retraction of the webbing during daily use, while simultaneously locking quickly in the event of a sudden overload. This solution supports the operation of the vehicle’s passive safety systems, working in conjunction with the seat and body structure.

Benefits of using an original seat belt

Using an original seat belt in the W177 model allows for maintaining compliance with the vehicle’s factory design assumptions. Key advantages include:

• secure fit to the mounting points in the rear part of the body,
• maintenance of the correct geometry of the webbing routing relative to the seat and the body,
• visual consistency with the interior thanks to the black finish,
• predictable operation of the locking mechanism in emergency situations.

Thanks to this, replacing a damaged element with an original counterpart allows for restoring the level of protection for rear seat passengers designed by the manufacturer without the need for vehicle structure modifications.

Use of a used part in the safety system

The element comes from the used parts segment, which enables an economical repair of the safety zone while maintaining the manufacturer’s original specification. In practice, this means the possibility of restoring the functionality of the factory seat belt system without the need to resort to replacements with unverified parameters.
