Installing a car seat correctly is crucial for your child’s safety. Car seats come equipped with specific parts designed to secure them properly in your vehicle. Two critical components you need to understand are the lower anchor attachments and the tether. These parts work together, or sometimes independently with your vehicle’s seat belt, to create a safe restraint system for your child.
Lower Anchor Attachments: Connecting to Your Vehicle
Lower anchor attachments are a key part of the LATCH (Lower Anchors and Tethers for CHildren) system. These attachments, found on the car seat, are designed to connect to the lower anchors in your vehicle’s seat.

Lower Anchor Function:
These attachments are primarily used for installing the car seat into your vehicle without using the vehicle’s seat belt. They provide a direct and often easier way to achieve a tight and secure installation. It’s important to note that there are weight limits associated with using lower anchors.
Tether: Enhancing Forward-Facing Car Seat Safety
The tether is a strap located on convertible, combination, and all-in-one car seats, specifically designed for forward-facing installations.

Tether Function:
The tether’s primary purpose is to secure a forward-facing car seat and significantly limit forward head movement in the event of a crash. By attaching the tether hook to the tether anchor in your vehicle, you add an extra layer of stability and protection. While most rear-facing car seat installations in the U.S. do not utilize a tether, it is strongly recommended to always use the tether when installing a forward-facing car seat, whether you are using the lower anchors or the vehicle’s seat belt for the main installation. Always consult both your car seat’s instruction manual and your vehicle’s owner’s manual for specific guidance on tether usage.
Lower Anchor Weight Limits: Knowing When to Switch to Seat Belts
It’s vital to be aware of the weight limits associated with lower anchors. Both vehicle and car seat manufacturers set these limits. You can typically find the lower anchor weight limit on a warning label or in the installation diagrams on the side of your car seat. If this information isn’t readily available, you can calculate the maximum child weight for lower anchor use by subtracting the car seat’s weight from 65 pounds. The car seat’s weight is usually found in its instruction manual.
Calculating Lower Anchor Weight Limit:
Lower anchor weight limit = 65 lbs – weight of car seat
Transitioning to Vehicle Seat Belts:
Once your child exceeds the weight limits specified by either the car seat or vehicle manufacturer for lower anchors, it is essential to stop using the lower anchor attachments. At this point, you must reinstall the car seat using the vehicle’s seat belt to ensure continued safety and proper installation.
