The LATCH system is designed to help secure attachments for child restraints. While you can use a vehicle's safety belts to secure your child seats to your vehicle, the LATCH system is designed to make the process easier. Not only that, the Insurance Institute of Highway Safety (IIHS) has concluded that child safety systems are more likely to be securely attached with the LATCH system is used.
Each vehicle's LATCH systems are rated by the IIHS according to 3 criteria. First, the accessibility of the lower anchors is evaluated. Next, the force needed to attach the lower anchors is examined. Finally, the clearance angle is measured. By examining these three criteria, the IIHS ensures that a LATCH system is easy to apply by just about any adult.
