BMW Seat Belt Extender Arm Left - Genuine BMW 72117334637

Product Information

The seat belt is a vital safety restraint system designed to secure occupants in their seats during vehicle operation. It helps minimize injury risk in the event of sudden stops or collisions by keeping the body properly positioned and reducing contact with interior components. Constructed from high-strength webbing, retractor mechanisms, and locking buckles, the seat belt is engineered for durability, reliability, and compliance with safety regulations. Proper function of the seat belt system is essential for occupant protection and overall vehicle safety.

• Fraying, cuts, or visible wear on the webbing – compromises the belt’s strength and effectiveness.
• Retractor malfunction – belt fails to extend, retract, or lock correctly.
• Damaged or faulty buckle – prevents secure latching or causes accidental release.

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
