Alpine A290 Seat Belt Extender | Certified Safety & Perfect Fit
Alpine A110 Seat Belt Extender | Certified Safety & Perfect Fit
A Seat Belt That Finally Fits Your Alpine
The A110, A290 and A390 are built light, low and focused on the drive, not on a buckle that digs in or a belt that barely reaches. Our Alpine seat belt extenders add the exact length you need, click straight into your factory buckle, and keep every safety standard intact.
The Problem
A tight cabin, a deeply bolstered bucket seat, or a little extra around the middle can turn buckling up into a daily struggle. When the belt will not reach or the buckle sits down out of sight, the temptation is to skip it altogether. That is the one thing you should never do in an Alpine.
The Fix
A rigid, ECE R16 certified extender that locks into your existing buckle and gives you the reach you need. No tools, no modification, no compromise on safety. Just click, buckle, and drive.
Built Around One Idea: Safety First, Comfort Always
ECE R16 Certified
Manufactured to the internationally recognised E4 or E8 safety specifications for 3-point seat belts, so the protection you rely on stays intact.
OEM-Quality Fit
Precision-matched to your Alpine's factory buckle, so it clicks in firmly and releases cleanly, every single time.
Click-and-Go
No tools, no trouble. The extender clicks into your existing seat belt in seconds and is ready to use immediately.
