Intended Use and Fitment for BMW E83 X3

The presented seat belt has been designed specifically for the BMW E83 X3 model, intended for installation on the rear seat on the right or left side. Thanks to the factory geometry of the retractor, mountings, and buckle, the component works with the original anchor points in the body, which facilitates installation and maintains compliance with the factory safety system configuration.

The black color of the webbing and covers ensures the belt harmoniously blends with most standard interior configurations of the BMW X3 E83, without requiring modifications to the upholstery or trim plastics.

Construction and Technical Specifications

The seat belt belongs to the Seat Belts and Parts category, meaning it is an active passenger protection system component. The construction includes a retractor with a locking mechanism, a webbing of appropriate strength, and a length adjustment mechanism tailored to the geometry of the rear seat in the BMW X3 E83.

• Vehicle Placement: Rear, right or left side – a single unit can be used on the appropriate side as intended.
• Black Color: Neutral, universal finish, matching factory BMW interiors.
• Original BMW Brand: Maintains factory manufacturing standards and body compatibility.

By using an original BMW solution, the belt integrates with the vehicle's standard mounting points and safety system, contributing to predictable vehicle behavior during sudden braking or collisions.

Condition, Origin, and Benefits of Choosing a Used OEM Part

The offered seat belt is a used component, sourced from dismantling. For many BMW owners, choosing an original, used component is a sensible alternative to aftermarket parts because:

• it maintains the factory build quality characteristic of BMW,
• it ensures a proper fit to the body structure and upholstery,
• it allows for cost reduction in repairs or interior restoration compared to new OEM parts.

Practical Application and Installation

The seat belt is installed in the rear of the vehicle, on the right or left side, at the factory mounting points of the BMW X3 E83. Thanks to the OEM construction, the replacement process is predictable for workshops specializing in the BMW brand – it does not require body modifications or adaptation of mountings, provided the vehicle has not been previously modified.

In practice, belt replacement is recommended, among other things, after a collision, if the retractor lock has engaged, if there are visible damages to the webbing, or during a comprehensive interior renovation. Using an original part helps maintain visual and functional consistency with the other belts in the vehicle.
