Buckle Up in Your Mercedes-Benz — Comfortably
If your Mercedes-Benz's seat belt doesn't reach, you don't need a workaround. You need an extender that clicks into your existing buckle and gives you the extra length to fasten your belt properly.
Our extenders add 3 to 26 inches of reach depending on the style you choose. No tools. No modifications. Click it in, buckle up, drive.
We carry extenders for 40 Mercedes-Benz models. Find your model below, or scroll down to compare styles.
Built for People Who Need More Reach
- Larger drivers and passengers — when the factory belt comes up short, an extender closes the gap so you can buckle in without strain
- Officers and first responders — duty belts, body armor, and equipment make standard seat belts too tight to fasten
- People with limited mobility — arthritis, injuries, or reduced range of motion can make reaching the buckle difficult
- Pregnant women — extra room for comfortable belt positioning as your body changes
- Fleet and NEMT operators — one extender handles a wide range of passengers across shifts
Three Styles for Your Mercedes-Benz
Regular
Flexible woven webbing that matches your factory belt. Adds 7 or 10 inches. The most popular choice for Mercedes-Benz owners. Black or gray.
Rigid
A solid extension that holds its shape upright, making the buckle easier to see and reach. Available in 3, 5, and 7 inches. Helpful when your Mercedes-Benz's buckle sits deep between the seat and console.
Adjustable
Slides from 9 inches to a full 26 inches. Same flexible webbing as the regular, with a built-in adjuster so multiple drivers can set their own length. One extender, any passenger.
Every Mercedes-Benz Extender Is Safety Certified
- E4 and E8 certified — the same international standard your factory seat belt is built to
- DOT-registered facility — manufactured in a US Department of Transportation registered factory
- Manufactured in an ISO-certified facility — quality management standards applied throughout production
- Break-strength tested — exceeds the minimum force requirements for three-point harness restraints
Your Mercedes-Benz's seat belt retractor, pretensioner, and airbag system all work normally with an extender installed. Nothing is modified or disabled.
