What is CINCH

CINCH is a small device that keeps your seat belt at the appropriate tension while driving. As you drive your seat belt can become slack and improperly positioned, reducing effectiveness and encouraging poor posture. CINCH is an innovative and simple solution for getting optimal performance from your seat belt. It just slides over the belt buckle to install.

Does CINCH fit my car?

CINCH was designed to fit most belt buckles installed in today's vehicles. If your buckle is especially chunky, you might have troubles installing the CINCH device. Fortunately, our generous return policy makes it incredibly simple to return items for a 100% refund. Installation of CINCH is dead simple. Just slide the CINCH over your buckle, buckle up, and give the belt a tug to tighten the lap section.

CINCH on the Tack

As a sports car enthusiast, CINCH is a great bang for your buck upgrade you can make to your car. Anyone with any race experience will tell you that stock seat belts are inadequate at keeping your body secure in the seat during performance driving. Wrestling with your car while your body jostles back and fourth leads to lower lap times and an overall less enjoyable experience. By keeping more tension on the lower portion of the seat belt, it can do a significantly better job of keeping your body secured in the seat. This allows you to focus more on driving, and increases your ability to provide smooth and precise inputs. While a 4-point harness and racing seat do provide the ultimate solution to these problems, they both come with massive financial and practicality barriers. CINCH is simply the easy solution for the everyday sporty driver.

CINCH Off-Road

Whether is overland, rock crawling, or just out getting muddy nothing throws you around your seat like some off-roading. CINCH can keep the tension on your lap to keep you down in your seat with your feet to the pedals and hands on the wheel. Increased control is going to improve your dives off the beaten path.

CINCH for Back Pain

CINCH eliminates seat belt slack to align your spine against your seat’s lumbar support. This helps prevent slouching to improve posture and comfort.

SEAT BELT SLACK = BACK STRAIN

Lumber support reduces back strain, but only if your seat belt is worn snug across the hips and pelvis. However as you drive, your seat belt becomes slack, reducing back support and increasing back strain by 75%.*

CINCH Keeps KIDS safe, secure & snug!

CINCH’s snug fit prevents the tendency of your child’s lap belt to loosen up during your car trip, even after it was properly secured at the start of the journey.

CINCH for Pregnancy

CINCH’s snug fit prevents the tendency of the lap belt to ride up onto the abdomen during your car trip, even after it was placed safely across the hips and pelvis at the start of the journey.

CINCH is designed to keep the lap belt comfortably below the bump (abdomen) and safely across the hips and pelvis during pregnancy, as strongly recommended by the American College of Obstetricians & Gynecologists.
