When a child grows out of his car booster seat, he may still be too short to comfortably wear a seatbelt. Frequently kids weighing between 50 and 100 pounds will pull the shoulder strap off and behind them, a very unsafe practice that defeats the use of a seatbelt. The ChildCare Seatbelt Adjuster slides onto the car’s seat belt and repositions the shoulder harness so that it rides across the shoulder properly, and not along the neck. The ChildCare unique, safe and very strong and it’s not just for kids–short adults may want to try the adjuster as well, especially in older vehicles without adjustable shoulder harness mounts.
