Intended Use and Fitment

The presented Mercedes W176 rear seat belt has been designed to work with factory mounting points on the rear seat, both on the right and left side. The vehicle placement is precisely defined, which facilitates the selection of the part when replacing it after a collision, pretensioner activation, or wear and tear.

The black shade of the belt upholstery helps maintain visual consistency of the interior, without the need to modify other equipment elements. This solution is particularly beneficial for post-accident repairs, where both safety and aesthetics are important.

Construction and Technical Function

The belt is part of the passive safety system, responsible for stably holding the passenger in their seat during sudden braking or impact. The OEM construction is optimized for:

• controlled webbing deflection under load,
• cooperation with pretensioners and force limiters (in accordance with the vehicle's factory configuration),
• proper webbing routing relative to mounting points and the buckle.

Thanks to this, the system maintains predictable operating parameters, which is crucial for the effectiveness of passenger protection on the rear seat.

Condition and Benefits of Choosing a Used Part

The item is offered as a used part, sourced from dismantling. For many users, this is a sensible compromise between repair cost and maintaining the original manufacturer's specifications. In practice, this means:

• retaining the factory mounting geometry and belt length,
• compatibility with the original safety systems in the specific model,
• reducing service costs while maintaining OEM standards.

Before installation, standard verification in a workshop is recommended, including checking the retractor mechanism and proper locking during a sudden pull, to ensure full functionality in everyday use.

Safety, Installation, and Practical Application

Replacing the seat belt is particularly important after SRS system activation or in case of visible webbing damage. Using an original rear belt for the Mercedes W176 allows for:

• restoring the factory level of protection for rear passengers,
• avoiding fitment issues typical of aftermarket parts of uncertain origin,
• maintaining compliance with technical inspection requirements regarding safety systems.

Installation should be performed by a qualified service center, adhering to the manufacturer's torque specifications and procedures, which minimizes the risk of system malfunction in an emergency situation.
