Behind the Scenes | Tether vs. No Tether Video

We're thrilled to have another video to demonstrate the importance of proper car seat usage (watch the video here). So many parents don't realize that taking a few extra minutes to install their child's forward-facing car seat using the top tether, could be the difference between their little one suffering a traumatic brain injury, or walking away from a crash with little to no injury. Here's a behind the scenes look at the testing, with some additional information about the seats, dummies, and testing parameters.

Selecting the dummies and seats:

The Anthropomorphic Test Device (ATD) or "crash test dummy" used in these tests was a 3 year old child dummy, weighing 35.65 pounds, with a standing height of 37.2 inches, and a seated height of 21.5 inches. The same dummy was used for both tests. The seats used for testing can be used forward-facing from 22 to 65 pounds, and 28 to 50 inches. While identical seats were used, a new seat was used for each test.

Installing the seats and securing the dummies:

Two nationally certified Child Passenger Safety Technicians from the Buckle Up With Brutus program were present throughout testing to install the car seats, and ensure that each child dummy was properly secured in their car seat.
For the testing using the top tether, the seat was installed using lower anchors and the tether anchor. As with any proper car seat installation, the seat was installed tight enough that it could not be moved side-to-side or front-to-back more than one inch. The dummy was positioned in the seat with the harness straps at shoulder level - remember, for forward-facing seats the harness should be at or above the shoulders! The harness was tightened until no excess webbing could be pinched.
For the test without the top tether, the seat was installed using only the lower anchors. As with any proper car seat installation, the seat was installed tight enough that it could not be moved side-to-side or front-to-back more than one inch. The dummy was positioned in the seat with the harness straps at shoulder level - remember, for forward-facing seats the harness straps should be at or above the shoulders! The harness was tightened until no excess webbing could be pinched.

Conducting the tests:

The speed of the tests was based on the Federal Motor Vehicle Safety Standard (FMVSS) 213, which specifies the testing condition requirements for child restraint systems used in motor vehicles. As such, a speed of 48 kilometers per hour (approximately 30 miles per hour) was targeted in the tests.

Acknowledgements:

We were fortunate enough to have access to the testing facilities and research engineers at the Transportation Research Center (TRC, Inc.) to conduct the sled testing that was used in the video. Evenflo graciously donated the seats for testing, and also provided input throughout the testing and video editing process.
