As a child passenger safety technician/instructor for the past twenty years, I am always amazed at how quickly technology changes in the field. Both car seat and vehicle manufacturers are constantly testing innovations, making it difficult to know exactly how to properly use a car seat. One innovation that tends to give caregivers problems is the tether. Tethers are now a standard feature on every car seat and they are meant to be used with either the seatbelt or the LATCH (Lower Anchors and Tethers for Children) system. Tether anchors are required in passenger vehicles made after 2001.
For most car seats, tethers are not meant to be used rear-facing. A rear-facing seat is designed to dip and rebound in a frontal crash, cradling and protecting its young passenger. It doesn’t require a tether to do its job correctly. Forward-facing seats are a different story and tethers make them safer by allowing less head movement and stress on the spinal cord during a crash. Especially in a frontal crash, a tether can prevent serious head and neck injury by securing the top of the car seat and preventing several inches of forward head movement.
A tether is a strap of webbing with a hook at the end. Tethers connect the top of the car seat to the vehicle. They should be used for every forward-facing car seat installation, regardless of whether LATCH or a seatbelt is used to secure the seat itself. Most tethers need to be tightened only enough to remove slack. The manual that comes with each car seat offers important information on how to attach and tighten the tether properly.
If you have any questions about car seats, ask a certified child passenger safety technician in your area. You can find one near you at http://cert.safekids.org/
